Nershimski. ?] I'm 62 years old. 123 00:05:53,020 --> 00:05:57,180 I've been disabled since I was 24. 124 00:05:57,180 --> 00:06:01,520 -Paul uses forearm crutches because his imputation 125 00:06:01,520 --> 00:06:05,000 doesn't allow for a prosthetic. 126 00:06:05,000 --> 00:06:08,180 Despite the fact that his forearm crutches don't really 127 00:06:08,180 --> 00:06:11,540 let him carry things while he's walking, for Paul, 128 00:06:11,540 --> 00:06:13,240 the most important thing is to be 129 00:06:13,240 --> 00:06:16,975 able to move around and go places. 130 00:06:16,975 --> 00:06:19,720 -And one the big dreams of my life 131 00:06:19,720 --> 00:06:21,936 has been to be able to carry around a coffee 132 00:06:21,936 --> 00:06:25,335 cup around the house like a normal human 133 00:06:25,335 --> 00:06:28,430 being with burning my fingers and ruining the rug. 134 00:06:28,430 --> 00:06:31,900 -What really drew me to Paul was just the very simple nature 135 00:06:31,900 --> 00:06:34,910 of what he wanted, something that you and I take 136 00:06:34,910 --> 00:06:40,070 for granted, just the ability to transport food and even just 137 00:06:40,070 --> 00:06:42,735 a cup of coffee from his crutches to his living room 138 00:06:42,735 --> 00:06:46,150 without spilling it all over his floor. 139 00:06:46,150 --> 00:06:49,446 -Cup full of water, not far from the brim, 140 00:06:49,446 --> 00:06:52,220 I would have to carry it like that, with my hand wrapped 141 00:06:52,220 --> 00:06:53,400 around the crutch handle. 142 00:06:53,400 --> 00:06:57,240 And maybe you can realized that would be a horror show. 143 00:06:57,240 --> 00:06:59,140 -He wants to carry a cup of coffee 144 00:06:59,140 --> 00:07:03,380 around without burning himself, and that's very, very different 145 00:07:03,380 --> 00:07:06,167 from other people, other clients, had in mind. 146 00:07:06,167 --> 00:07:07,625 But this project's very mechanical. 147 00:07:07,625 --> 00:07:10,476 It' very simple, yet a really challenging problem. 148 00:07:10,476 --> 00:07:12,690 -That may seem like not much to most people, 149 00:07:12,690 --> 00:07:13,620 but it's huge to me. 150 00:07:17,958 --> 00:07:20,010 -There are many, many ideas floating around, 151 00:07:20,010 --> 00:07:23,150 but one of them is a gyroscope, something 152 00:07:23,150 --> 00:07:24,780 that would with the gyroscopic motion 153 00:07:24,780 --> 00:07:29,234 that can keep the coffee level while he's with his crutches. 154 00:07:29,234 --> 00:07:32,010 And this is one of the designs that we 155 00:07:32,010 --> 00:07:38,460 saw online that kind of resembles what we want to have. 156 00:07:38,460 --> 00:07:40,174 It's basically a cup holder that allows 157 00:07:40,174 --> 00:07:42,590 motion, that allows it to stay level when there is motion. 158 00:07:46,900 --> 00:07:52,345 -There's a kind of silicon cover that goes over the coffee mug, 159 00:07:52,345 --> 00:07:55,305 and if it gets a good seal, then it works really, really well. 160 00:07:57,530 --> 00:08:03,060 -Silicone cover does wonders-- nothing. 161 00:08:03,060 --> 00:08:04,469 [LAUGHTER] 162 00:08:04,469 --> 00:08:05,635 -So you have water in there? 163 00:08:05,635 --> 00:08:09,030 -Yeah, it's pretty full. 164 00:08:09,030 --> 00:08:10,485 -Wow, that's great. 165 00:08:10,485 --> 00:08:11,455 -That really works. 166 00:08:11,455 --> 00:08:13,360 I mean, that's full. 167 00:08:13,360 --> 00:08:16,465 I try no to over think things, get like a real simple thing 168 00:08:16,465 --> 00:08:18,910 that I couldn't do. 169 00:08:18,910 --> 00:08:21,160 And you're making it so I'm going to be able to do it. 170 00:08:26,374 --> 00:08:29,220 [END PLAYBACK] 171 00:08:29,220 --> 00:08:30,960 LEXI DIEN: So, as you saw in the video, 172 00:08:30,960 --> 00:08:33,165 we've been trying out a lot of different prototypes 173 00:08:33,165 --> 00:08:38,390 with Paul, mainly things that we found online, 174 00:08:38,390 --> 00:08:43,630 some things like this on-stage cup holder, which is basically 175 00:08:43,630 --> 00:08:46,850 a cup holder that can statically be just clicked 176 00:08:46,850 --> 00:08:53,770 on to his crutch, and it doesn't help tipping at all, 177 00:08:53,770 --> 00:08:58,890 so if it was an open cup, it would just pour out. 178 00:08:58,890 --> 00:09:02,690 But it's something that helps the hands-free aspect. 179 00:09:02,690 --> 00:09:06,020 And something like the water bottle holder 180 00:09:06,020 --> 00:09:08,740 would also do this maybe, except for it might not 181 00:09:08,740 --> 00:09:10,800 fit a mug very well. 182 00:09:10,800 --> 00:09:16,700 So right now we're looking into some snap-on clamps, 183 00:09:16,700 --> 00:09:19,250 like this one. 184 00:09:19,250 --> 00:09:23,330 It would just be easy to snap on and off of his crutch 185 00:09:23,330 --> 00:09:29,040 so that he could take it off and on the crutch 186 00:09:29,040 --> 00:09:31,160 very easily and very quickly. 187 00:09:31,160 --> 00:09:32,535 So I'm going to pass these around 188 00:09:32,535 --> 00:09:35,910 for people to look at it. 189 00:09:35,910 --> 00:09:39,830 Some ideas for the no-spill solution-- as you 190 00:09:39,830 --> 00:09:42,370 saw, we were thinking gyroscope maybe. 191 00:09:42,370 --> 00:09:44,950 It turns out that that's a little bit more complicated 192 00:09:44,950 --> 00:09:47,300 than we thought it would be. 193 00:09:47,300 --> 00:09:49,200 It's a little touchy. 194 00:09:49,200 --> 00:09:52,250 So we're trying to look a little bit in a different way. 195 00:09:52,250 --> 00:09:55,860 The second thing we did was the CoverFlex, 196 00:09:55,860 --> 00:09:57,209 which we showed in the video. 197 00:09:57,209 --> 00:09:59,500 It takes a little bit of time to put on and off though, 198 00:09:59,500 --> 00:10:03,370 so we were looking into some other ways, which one of them 199 00:10:03,370 --> 00:10:04,730 is this suction cover. 200 00:10:07,310 --> 00:10:10,950 So this is a mug, very easy. 201 00:10:10,950 --> 00:10:12,843 I'm going to pour some water into it 202 00:10:12,843 --> 00:10:20,340 and then put one of these section covers on top of it, 203 00:10:20,340 --> 00:10:23,200 and no water will spill out. 204 00:10:23,200 --> 00:10:26,060 So we're hoping that this will be able to work for his mugs 205 00:10:26,060 --> 00:10:29,180 as well, and work on that a little bit. 206 00:10:29,180 --> 00:10:33,100 Another thing that we're looking into, which is coming in today, 207 00:10:33,100 --> 00:10:37,190 is this Spill-Not, which is a device that's specifically 208 00:10:37,190 --> 00:10:40,290 made to counteract movement. 209 00:10:40,290 --> 00:10:42,370 When you place a mug on it, basically, that 210 00:10:42,370 --> 00:10:47,070 would make it so that it wouldn't spill hopefully. 211 00:10:47,070 --> 00:10:49,000 So we're looking into that a little bit more. 212 00:10:56,817 --> 00:10:58,400 BRADY ENSTAD: So at our client meaning 213 00:10:58,400 --> 00:10:59,941 for the first prototype, like I said, 214 00:10:59,941 --> 00:11:04,320 we showed Paul the on-stage microphone clip, 215 00:11:04,320 --> 00:11:08,500 and we showed him the CoverFlex silicon cover, 216 00:11:08,500 --> 00:11:10,450 and we left those with him this past week, 217 00:11:10,450 --> 00:11:14,600 and we're going to go back on Wednesday after class 218 00:11:14,600 --> 00:11:16,970 and get is feedback on those. 219 00:11:16,970 --> 00:11:19,210 He was actually more excited because we told him 220 00:11:19,210 --> 00:11:20,770 that the Spill-Not was coming. 221 00:11:20,770 --> 00:11:23,649 He was more excited about that than anything else. 222 00:11:23,649 --> 00:11:25,440 But the CoverFlex, as you saw in the video, 223 00:11:25,440 --> 00:11:28,300 actually worked really, really well. 224 00:11:28,300 --> 00:11:32,190 The only difficulty with it is that once you have it 225 00:11:32,190 --> 00:11:34,209 on and take it off, like if there's 226 00:11:34,209 --> 00:11:36,250 been any spillage at all, it's a little difficult 227 00:11:36,250 --> 00:11:38,930 to get it back on again, which is why we decided to go 228 00:11:38,930 --> 00:11:41,240 with these suction covers. 229 00:11:41,240 --> 00:11:43,932 The only problem with those is they might not fit his mugs. 230 00:11:43,932 --> 00:11:45,390 So there's a possibility that we'll 231 00:11:45,390 --> 00:11:49,120 have to do a little bit more shopping around 232 00:11:49,120 --> 00:11:52,880 to find larger covers that will probably fit his mugs. 233 00:11:52,880 --> 00:11:57,920 That's honestly the biggest problem is his mugs are huge. 234 00:11:57,920 --> 00:12:01,880 So coffee addict, or something, but yeah, 235 00:12:01,880 --> 00:12:05,390 like I said he's super, duper excited about the Spill-Not. 236 00:12:05,390 --> 00:12:08,540 And honestly one of our biggest visions 237 00:12:08,540 --> 00:12:10,942 for what will end up happening is 238 00:12:10,942 --> 00:12:12,900 that we'll be able to incorporate the Spill-Not 239 00:12:12,900 --> 00:12:15,220 with a quick on-and-off clamp, like the one that's 240 00:12:15,220 --> 00:12:15,970 going around. 241 00:12:18,750 --> 00:12:22,535 Like I said, the clamp, it works really well on-stage, 242 00:12:22,535 --> 00:12:24,160 but it doesn't really prevent spilling, 243 00:12:24,160 --> 00:12:27,780 and it's pretty slow because it's a screw-on/screw-off type 244 00:12:27,780 --> 00:12:31,750 mechanism, as opposed to just a quick clamp. 245 00:12:31,750 --> 00:12:33,770 He liked the CoverFlex, but if there's 246 00:12:33,770 --> 00:12:36,480 something that's easier, like those suction covers, 247 00:12:36,480 --> 00:12:38,140 then he would prefer that. 248 00:12:38,140 --> 00:12:41,570 So for future work, as I said, we're 249 00:12:41,570 --> 00:12:45,440 going to be testing more off-the-shell prototypes, 250 00:12:45,440 --> 00:12:48,010 different suction mug covers maybe. 251 00:12:48,010 --> 00:12:50,160 The bike cup holder, we haven't entirely 252 00:12:50,160 --> 00:12:52,326 abandoned that idea yet either. 253 00:12:52,326 --> 00:12:53,700 And then obviously, the Spill-Not 254 00:12:53,700 --> 00:12:55,075 is what we're most excited about. 255 00:12:56,752 --> 00:12:58,460 We're going to go get feedback from Paul. 256 00:12:58,460 --> 00:13:01,602 And if he has some feedback for us 257 00:13:01,602 --> 00:13:03,810 that we can't meet with any off-the-shelf prototypes, 258 00:13:03,810 --> 00:13:05,920 then we're just going to do some customization 259 00:13:05,920 --> 00:13:08,350 for his final prototype. 260 00:13:08,350 --> 00:13:09,850 PROFESSOR: So first of all, you guys 261 00:13:09,850 --> 00:13:13,440 have scoped this really well, in the sense that this is a really 262 00:13:13,440 --> 00:13:18,410 well-defined problem that you've worked out with Paul. 263 00:13:18,410 --> 00:13:22,960 And it seems like you're finding a lot of pieces 264 00:13:22,960 --> 00:13:25,940 to the solution that are already out there, that maybe you 265 00:13:25,940 --> 00:13:30,080 can combine to make something that's really good for him. 266 00:13:30,080 --> 00:13:33,555 So I would encourage you, or have you thought about-- let 267 00:13:33,555 --> 00:13:35,610 me phrase this as a question. 268 00:13:35,610 --> 00:13:38,170 Have you thought about the sustainability 269 00:13:38,170 --> 00:13:39,180 of your solution? 270 00:13:39,180 --> 00:13:44,170 So these cover flex things, for example, how do they fail? 271 00:13:44,170 --> 00:13:47,210 And how will things break? 272 00:13:47,210 --> 00:13:49,450 And what is going to have to replace? 273 00:13:49,450 --> 00:13:51,360 And sort of what is the lifetime of what 274 00:13:51,360 --> 00:13:52,984 you're building for him? 275 00:13:52,984 --> 00:13:55,150 BRADY ENSTAD: So the great thing about the CoverFlex 276 00:13:55,150 --> 00:13:58,730 is that it's actually oven and dishwasher safe. 277 00:13:58,730 --> 00:14:03,100 So presumably, it's got a relatively long life cycle, 278 00:14:03,100 --> 00:14:07,250 and we're thinking, honestly, on the order of, hopefully, 279 00:14:07,250 --> 00:14:12,400 years because it is oven and dishwasher safe, 280 00:14:12,400 --> 00:14:15,030 unless he somehow super-duper heats it beyond what it's rated 281 00:14:15,030 --> 00:14:16,696 for, which I don't really know how you'd 282 00:14:16,696 --> 00:14:20,230 do that because it's oven safe. 283 00:14:20,230 --> 00:14:26,387 And as far as the clamp, the hands-free solution goes, 284 00:14:26,387 --> 00:14:28,095 frankly it's a purely mechanical systems. 285 00:14:28,095 --> 00:14:31,340 So unless he finds some way to snap off 286 00:14:31,340 --> 00:14:35,100 the clamp, which it could happen, don't get me wrong, 287 00:14:35,100 --> 00:14:37,900 but the great thing about these components that we found 288 00:14:37,900 --> 00:14:39,900 is that they're actually relatively inexpensive. 289 00:14:39,900 --> 00:14:44,120 And so the idea we have is that after the class 290 00:14:44,120 --> 00:14:46,880 is over we would leave him with these part numbers. 291 00:14:46,880 --> 00:14:49,210 Because he has a computer at home-- he's tech savvy. 292 00:14:49,210 --> 00:14:53,400 He used to work in IT-- so if something were to break, 293 00:14:53,400 --> 00:14:55,990 he could just purchased himself another one, 294 00:14:55,990 --> 00:14:59,990 assuming that there's not a great deal of customization 295 00:14:59,990 --> 00:15:01,080 that goes into it. 296 00:15:01,080 --> 00:15:04,620 And we don't actually know the scope of customization that's 297 00:15:04,620 --> 00:15:07,622 going to have to go into it just yet because, as I said, 298 00:15:07,622 --> 00:15:09,580 what we're most excited about is the Spill-Not, 299 00:15:09,580 --> 00:15:11,080 and we're not really sure how that's 300 00:15:11,080 --> 00:15:15,029 going to be incorporated with the clamp just yet. 301 00:15:15,029 --> 00:15:16,945 PROFESSOR 2: So I would just kind of encourage 302 00:15:16,945 --> 00:15:19,111 as you're thinking about the failure modes, not just 303 00:15:19,111 --> 00:15:20,980 the individual failure modes, but kind 304 00:15:20,980 --> 00:15:23,130 of the cross-coupled failure modes-- 305 00:15:23,130 --> 00:15:26,110 as I was looking at the seal, one of the ways 306 00:15:26,110 --> 00:15:29,550 that you release the seal is by kind of flipping that edge, 307 00:15:29,550 --> 00:15:32,230 so you want to be careful that that edge isn't actually 308 00:15:32,230 --> 00:15:34,660 going to be affected by whatever your mechanism is 309 00:15:34,660 --> 00:15:35,636 for holding it. 310 00:15:35,636 --> 00:15:37,260 So think about the kind of the coupling 311 00:15:37,260 --> 00:15:39,115 that you get between your solutions, 312 00:15:39,115 --> 00:15:42,780 and not just the independent issues that you have with them. 313 00:15:42,780 --> 00:15:45,530 One of the questions that I had for you was regarding 314 00:15:45,530 --> 00:15:48,610 your performance metrics, how you selected those on/off 315 00:15:48,610 --> 00:15:51,280 times, and how that related to his function 316 00:15:51,280 --> 00:15:54,920 versus the mechanical structure itself? 317 00:15:54,920 --> 00:15:57,670 And kind of from looking at some of your video, 318 00:15:57,670 --> 00:15:59,960 I'm wondering-- I couldn't really 319 00:15:59,960 --> 00:16:04,090 tell if he had any additional tremors or other issues 320 00:16:04,090 --> 00:16:06,000 as well that might affect his function that 321 00:16:06,000 --> 00:16:07,160 might affect that timing. 322 00:16:07,160 --> 00:16:09,950 So if you could just talk on that generation of timing? 323 00:16:09,950 --> 00:16:13,890 BRADY ENSTAD: Yeah, sure, so honestly, we just asked Paul. 324 00:16:13,890 --> 00:16:17,480 We said, Paul, how quickly do you want this thing be put on 325 00:16:17,480 --> 00:16:19,090 and be taken off? 326 00:16:19,090 --> 00:16:21,720 And he said, well, relatively quickly, 327 00:16:21,720 --> 00:16:23,710 and he wouldn't give us a solid number. 328 00:16:23,710 --> 00:16:26,260 So we were just like, OK, you know, 329 00:16:26,260 --> 00:16:29,030 20 seconds is a little long. 330 00:16:29,030 --> 00:16:31,470 10 seconds seems like a reasonable time. 331 00:16:31,470 --> 00:16:34,770 The great thing about Paul is the only disability 332 00:16:34,770 --> 00:16:37,470 that he has is the fact that his leg is amputated. 333 00:16:37,470 --> 00:16:40,980 So doesn't have any tremors or anything 334 00:16:40,980 --> 00:16:43,320 else, any other sort of disability. 335 00:16:43,320 --> 00:16:47,930 So I mean, as we talked about actually in lecture 336 00:16:47,930 --> 00:16:49,890 earlier today, it's possible as he gets older, 337 00:16:49,890 --> 00:16:52,672 those hands might start shaking and that sort of thing. 338 00:16:52,672 --> 00:16:54,880 But that's actually why we're excited about the clamp 339 00:16:54,880 --> 00:16:56,840 is because there's less precision involved. 340 00:16:56,840 --> 00:16:59,446 It's just a pretty simple snapping motion. 341 00:17:02,410 --> 00:17:04,260 So as far as like generating those numbers, 342 00:17:04,260 --> 00:17:07,030 it was just basically a kind of a general feeling 343 00:17:07,030 --> 00:17:10,730 we got from Paul, and we went with, well, 344 00:17:10,730 --> 00:17:12,670 what do you think about these numbers? 345 00:17:12,670 --> 00:17:14,800 And the great thing about Paul is also 346 00:17:14,800 --> 00:17:18,160 one of the worst things he's incredibly laid back, 347 00:17:18,160 --> 00:17:21,890 so he wasn't particularly zealous about giving 348 00:17:21,890 --> 00:17:23,170 us had numbers. 349 00:17:23,170 --> 00:17:24,760 So he was pretty willing to along 350 00:17:24,760 --> 00:17:25,710 with anything that we suggested. 351 00:17:25,710 --> 00:17:28,251 PROFESSOR 2: What are ways that you think that you guys might 352 00:17:28,251 --> 00:17:30,730 be able to validate those numbers a little bit more 353 00:17:30,730 --> 00:17:32,480 as you keep going and looking at some 354 00:17:32,480 --> 00:17:34,340 of these different designs? 355 00:17:34,340 --> 00:17:38,880 BRADY ENSTAD: Sure, so if you take a look at the clamp, 356 00:17:38,880 --> 00:17:40,880 between positioning it and snapping it, 357 00:17:40,880 --> 00:17:43,820 I think you're probably looking at realistically probably 358 00:17:43,820 --> 00:17:45,090 less than five seconds. 359 00:17:45,090 --> 00:17:50,570 It's not real picky about where you put it on the crutch. 360 00:17:50,570 --> 00:17:52,940 So obviously, we're just going to keep 361 00:17:52,940 --> 00:17:56,450 adjusting those numbers as what's 362 00:17:56,450 --> 00:17:59,937 realistic becomes more apparent. 363 00:17:59,937 --> 00:18:01,770 Like I said, we don't really know the degree 364 00:18:01,770 --> 00:18:04,480 of customization we're going to have to go to yet, especially 365 00:18:04,480 --> 00:18:08,120 if we're going to incorporate the Spill-Not. 366 00:18:08,120 --> 00:18:11,265 So once we get that and we do a little bit more prototyping, 367 00:18:11,265 --> 00:18:13,820 I'd be able to give you more solid answer for that. 368 00:18:13,820 --> 00:18:17,800 But as of right now, we don't really know. 369 00:18:17,800 --> 00:18:20,050 PROFESSOR 3: I am a coffee aficionado, 370 00:18:20,050 --> 00:18:24,097 and I just am OCD about the cup that I have. 371 00:18:24,097 --> 00:18:27,610 I have two or three mugs that I just love. 372 00:18:27,610 --> 00:18:31,090 I can press the Keurig twice, and it fills it up just right. 373 00:18:31,090 --> 00:18:32,080 So I get that. 374 00:18:32,080 --> 00:18:34,320 But I'm wondering, have you talked 375 00:18:34,320 --> 00:18:37,830 with this gentleman about his ability or willingness 376 00:18:37,830 --> 00:18:39,240 to negotiate? 377 00:18:39,240 --> 00:18:43,330 To me, one of the obvious solutions 378 00:18:43,330 --> 00:18:47,060 would be to have-- because he has good hand function, 379 00:18:47,060 --> 00:18:51,300 presumably-- is to fill up a thermos mug 380 00:18:51,300 --> 00:18:55,050 and have a simple clip that you can put on his foreleg 381 00:18:55,050 --> 00:18:58,320 crutches, walk to a table, and pour the coffee 382 00:18:58,320 --> 00:19:01,805 into his delightful cup. 383 00:19:01,805 --> 00:19:04,430 BRADY ENSTAD: So that's actually one of the very first thoughts 384 00:19:04,430 --> 00:19:06,780 that we had, and we asked Paul about that. 385 00:19:06,780 --> 00:19:10,100 And his reply honestly surprised us a little bit. 386 00:19:10,100 --> 00:19:12,990 He's not honestly concerned about carrying 387 00:19:12,990 --> 00:19:15,340 the cup of coffee so much for himself, 388 00:19:15,340 --> 00:19:17,830 as it is that he wants to help his wife out. 389 00:19:17,830 --> 00:19:21,590 Because while he was stuck in the wheelchair, he was really, 390 00:19:21,590 --> 00:19:23,500 really reliant on her, and so he wants 391 00:19:23,500 --> 00:19:26,536 to be able to carry a cup of coffee for his wife. 392 00:19:26,536 --> 00:19:27,910 And his whole thing about that is 393 00:19:27,910 --> 00:19:29,840 that I want to be able to carry it in the mug 394 00:19:29,840 --> 00:19:32,320 and just give it to her, and I don't 395 00:19:32,320 --> 00:19:36,182 want have to pour it out at the table or anything like that. 396 00:19:36,182 --> 00:19:38,598 PROFESSOR 4: One or two quick questions from the audience. 397 00:19:41,311 --> 00:19:43,977 AUDIENCE: So his Paul willing to have something on his crutches, 398 00:19:43,977 --> 00:19:48,097 or is that [INAUDIBLE], like the [INAUDIBLE]? 399 00:19:48,097 --> 00:19:50,680 BRADY ENSTAD: So that's why we were talking about quick on/off 400 00:19:50,680 --> 00:19:53,800 times, and the answer to that is, no, not really. 401 00:19:53,800 --> 00:19:56,860 He's OK with using it for the short period of time 402 00:19:56,860 --> 00:19:59,260 that it takes to transport the cup of coffee. 403 00:19:59,260 --> 00:20:00,760 But once he gets to the couch, he 404 00:20:00,760 --> 00:20:03,515 wants to be able to take it off because the way 405 00:20:03,515 --> 00:20:05,640 that he stores his crutches when he's sitting down, 406 00:20:05,640 --> 00:20:08,270 is he puts them on the floor. 407 00:20:08,270 --> 00:20:10,930 And so if there's anything attached to them 408 00:20:10,930 --> 00:20:13,880 that might possibly get in the way was his concerned. 409 00:20:13,880 --> 00:20:15,980 So the quicker on/off time, the better. 410 00:20:17,507 --> 00:20:19,132 PROFESSOR 4: [INAUDIBLE] last question, 411 00:20:19,132 --> 00:20:21,800 then we can have Team Margaret also begin to set up as well. 412 00:20:21,800 --> 00:20:23,883 PROFESSOR 3: The other quick thing I wanted to ask 413 00:20:23,883 --> 00:20:26,480 is, have you consulted an occupational therapist 414 00:20:26,480 --> 00:20:30,930 at all, someone who deals with these kinds of approaches 415 00:20:30,930 --> 00:20:32,890 on a daily basis? 416 00:20:32,890 --> 00:20:38,220 There might be some other simple solution that-- or maybe not so 417 00:20:38,220 --> 00:20:40,280 simple solution, but an established 418 00:20:40,280 --> 00:20:43,890 solution that someone has already dealt with. 419 00:20:43,890 --> 00:20:47,420 Because obviously, amputation and this kind of injury 420 00:20:47,420 --> 00:20:50,000 is fairly common and ubiquitous. 421 00:20:50,000 --> 00:20:52,340 BRADY ENSTAD: And the answer to that is, no, we haven't. 422 00:20:52,340 --> 00:20:53,930 But that sounds like a really great idea, 423 00:20:53,930 --> 00:20:54,950 so we'll look into that. 424 00:21:00,384 --> 00:21:01,372 PROFESSOR 4: Thank you. 425 00:21:01,372 --> 00:21:02,247 BRADY ENSTAD: Thanks. 426 00:21:08,439 --> 00:21:09,730 TANYA TALKAR: So, hi, everyone. 427 00:21:09,730 --> 00:21:11,080 We're Team Margaret. 428 00:21:11,080 --> 00:21:11,825 I'm Tanya. 429 00:21:11,825 --> 00:21:13,254 LAURA D'AQUILA: I'm Laura. 430 00:21:13,254 --> 00:21:14,920 TANYA TALKAR: And Beth his third member, 431 00:21:14,920 --> 00:21:18,980 but she's unable to get make it to the presentation today. 432 00:21:18,980 --> 00:21:20,039 So this is the team. 433 00:21:20,039 --> 00:21:22,330 I think we might have shown you this picture last week, 434 00:21:22,330 --> 00:21:24,927 but this is Margaret, our client. 435 00:21:24,927 --> 00:21:26,510 Interesting story about this picture-- 436 00:21:26,510 --> 00:21:28,093 she was actually the one who suggested 437 00:21:28,093 --> 00:21:30,370 that we take a selfie. 438 00:21:30,370 --> 00:21:32,510 So she's a great person. 439 00:21:32,510 --> 00:21:34,562 So a little bit about her as a person. 440 00:21:34,562 --> 00:21:37,020 She is an artist, so she loves to paint, loves to make arts 441 00:21:37,020 --> 00:21:37,519 and crafts. 442 00:21:37,519 --> 00:21:40,100 Her room is filled with a bunch of crafts. 443 00:21:40,100 --> 00:21:42,350 She's also an advocate, so she's on the Safety Council 444 00:21:42,350 --> 00:21:44,141 for The Boston Home, which means that she's 445 00:21:44,141 --> 00:21:46,450 talking a lot with residents to make sure that they are 446 00:21:46,450 --> 00:21:50,080 comfortable with their position at The Boston Home 447 00:21:50,080 --> 00:21:51,390 and everything that's going on. 448 00:21:51,390 --> 00:21:54,017 And Laura will talk a little bit about The Boston Home. 449 00:21:54,017 --> 00:21:54,850 She's also a friend. 450 00:21:54,850 --> 00:21:58,060 She FaceTimes a lot on her iPad with friends and family, 451 00:21:58,060 --> 00:22:00,310 And she's an immensely helpful mentor, 452 00:22:00,310 --> 00:22:02,445 not only to us, but also all of the other residents 453 00:22:02,445 --> 00:22:04,800 of the Boston Home. 454 00:22:04,800 --> 00:22:06,740 So about her disability-- she was 455 00:22:06,740 --> 00:22:08,660 diagnosed with multiple sclerosis, 456 00:22:08,660 --> 00:22:11,590 and she decided on her own to live at The Boston Home. 457 00:22:11,590 --> 00:22:13,220 So she has been at The Boston Home 458 00:22:13,220 --> 00:22:17,321 for about eight years, gotten during admission process. 459 00:22:17,321 --> 00:22:19,070 She gets around on a motorized wheelchair. 460 00:22:19,070 --> 00:22:20,970 All of the resonance have wheelchairs, 461 00:22:20,970 --> 00:22:22,410 and she's relatively independent. 462 00:22:22,410 --> 00:22:26,560 She has some fatigue in terms of trying to sign documents, 463 00:22:26,560 --> 00:22:29,255 or after using her iPad for a while, she will get fatigued, 464 00:22:29,255 --> 00:22:31,110 and her fingers will drag. 465 00:22:31,110 --> 00:22:33,050 But she is still relatively independent. 466 00:22:33,050 --> 00:22:35,950 And she was a social worker before she 467 00:22:35,950 --> 00:22:37,910 came to The Boston Home, which means 468 00:22:37,910 --> 00:22:40,752 that all of her thoughts and actions are really altruistic. 469 00:22:40,752 --> 00:22:42,460 She's always thinking about other people. 470 00:22:45,175 --> 00:22:46,550 LAURA D'AQUILA: So this over here 471 00:22:46,550 --> 00:22:48,050 is a picture of The Boston Home. 472 00:22:48,050 --> 00:22:50,180 It's located in Dorchester, Massachusetts. 473 00:22:50,180 --> 00:22:53,300 And Beth, Tanya, and I go visit it every Friday 474 00:22:53,300 --> 00:22:55,940 to meet with Margaret, other residents, and staff 475 00:22:55,940 --> 00:22:57,460 members of the home. 476 00:22:57,460 --> 00:22:59,390 To tell you a little bit more about the home, 477 00:22:59,390 --> 00:23:02,570 it was founded in 1881 as a long-term care 478 00:23:02,570 --> 00:23:05,330 center for adults with multiple sclerosis 479 00:23:05,330 --> 00:23:11,070 and other progressive neurodegenerative diseases. 480 00:23:11,070 --> 00:23:14,510 The average resident in The Boston Home is 58 years old, 481 00:23:14,510 --> 00:23:16,950 and The Boston Home places great emphasis 482 00:23:16,950 --> 00:23:18,844 on independence of residents. 483 00:23:18,844 --> 00:23:20,260 So we'll see later on that there's 484 00:23:20,260 --> 00:23:22,650 a lot of assistive technology that does 485 00:23:22,650 --> 00:23:24,180 exist within The Boston Home. 486 00:23:24,180 --> 00:23:29,420 There's 96 residents in the home and approximately 200 staff 487 00:23:29,420 --> 00:23:30,260 members. 488 00:23:30,260 --> 00:23:32,750 And it's a really nice place to live. 489 00:23:32,750 --> 00:23:36,990 They have activities, meetings, other social events, 490 00:23:36,990 --> 00:23:41,140 and it's known nationally for providing exceptional care 491 00:23:41,140 --> 00:23:42,035 to residents. 492 00:23:44,740 --> 00:23:48,020 And this over here is a picture of Don, one of our panelists. 493 00:23:48,020 --> 00:23:50,320 He's done a lot of great work in the home 494 00:23:50,320 --> 00:23:53,040 for making sure that residents do have access 495 00:23:53,040 --> 00:23:54,780 to assistive technology. 496 00:23:54,780 --> 00:23:58,530 For example, he mounts iPads on the motorized wheelchairs 497 00:23:58,530 --> 00:23:59,700 of residents. 498 00:23:59,700 --> 00:24:01,940 He also has a 3D printer that he's 499 00:24:01,940 --> 00:24:04,690 used to design pieces of assistive technology. 500 00:24:08,575 --> 00:24:10,366 TANYA TALKAR: So specifically, the activity 501 00:24:10,366 --> 00:24:13,630 that we've been working with for the past month has 502 00:24:13,630 --> 00:24:16,470 been the nurse call system or the call light system. 503 00:24:16,470 --> 00:24:18,890 And so what this is, is that residents, 504 00:24:18,890 --> 00:24:21,530 if they're in their room, can press a button-- we'll show it 505 00:24:21,530 --> 00:24:24,370 in a bit-- to call a nurse and call and aide 506 00:24:24,370 --> 00:24:26,120 to come and help them in their room. 507 00:24:26,120 --> 00:24:27,860 So there's a wired-in call light system. 508 00:24:27,860 --> 00:24:30,520 It's a button that it has been wired to the wall, 509 00:24:30,520 --> 00:24:33,290 and nurses are currently trained to place this button 510 00:24:33,290 --> 00:24:34,800 in the middle of bed. 511 00:24:34,800 --> 00:24:36,500 Many times though, it's forgotten about. 512 00:24:36,500 --> 00:24:38,320 So it's either not placed in the middle of the better, 513 00:24:38,320 --> 00:24:40,030 or it's placed in an unreachable spot. 514 00:24:40,030 --> 00:24:42,520 So Margaret sometimes has to come up to a table 515 00:24:42,520 --> 00:24:44,300 and has to either pull on the wire 516 00:24:44,300 --> 00:24:47,500 or pull on sheets to try and get the button. 517 00:24:47,500 --> 00:24:49,610 And there's also just no way of using the system 518 00:24:49,610 --> 00:24:51,370 if the resident is outside the home. 519 00:24:51,370 --> 00:24:51,870 So. 520 00:24:51,870 --> 00:24:54,960 For example, there was a resident who had gone outside, 521 00:24:54,960 --> 00:24:57,220 got stuck in a ditch, and his wheelchair tipped over, 522 00:24:57,220 --> 00:25:00,260 and he was unable to call The Boston Home to let them 523 00:25:00,260 --> 00:25:01,570 know that this has happened. 524 00:25:01,570 --> 00:25:04,640 So they had to have someone who was passing by tell them 525 00:25:04,640 --> 00:25:06,830 that that happened. 526 00:25:06,830 --> 00:25:08,640 So this is the call light system. 527 00:25:08,640 --> 00:25:10,160 The button is pretty easy to press. 528 00:25:10,160 --> 00:25:12,400 It's just like a simple press. 529 00:25:12,400 --> 00:25:15,210 But, again, it's placed in this kind of inconvenient spot, 530 00:25:15,210 --> 00:25:16,346 where Margaret can't reach. 531 00:25:16,346 --> 00:25:17,720 She doesn't have much of a reach, 532 00:25:17,720 --> 00:25:22,410 so she can't reach up to press the button if need be. 533 00:25:22,410 --> 00:25:24,710 And so in addition to that, there's some other issues. 534 00:25:24,710 --> 00:25:28,170 Only one nurse is allowed to answer the calls at any time. 535 00:25:28,170 --> 00:25:28,920 Her name's Angela. 536 00:25:28,920 --> 00:25:30,230 And so she sit at the front desk, 537 00:25:30,230 --> 00:25:31,490 and this takes a long time if there 538 00:25:31,490 --> 00:25:33,060 are multiple residents calling in 539 00:25:33,060 --> 00:25:35,270 or if she has gone from the desk and has to address 540 00:25:35,270 --> 00:25:37,660 another resident's issues. 541 00:25:37,660 --> 00:25:41,660 So an aide also has to come in to turn off the call system, 542 00:25:41,660 --> 00:25:43,750 otherwise it keeps on beeping, and that 543 00:25:43,750 --> 00:25:46,617 is quite annoying for both the resident and the nurse. 544 00:25:46,617 --> 00:25:48,700 Many times, if there are two rooms within a suite, 545 00:25:48,700 --> 00:25:50,950 as it is with Margaret, so enter a door 546 00:25:50,950 --> 00:25:53,520 and there are two rooms there, sometimes the wrong room 547 00:25:53,520 --> 00:25:57,390 is answered, so you'll have the nurse call into the other room. 548 00:25:57,390 --> 00:25:59,850 And since this is a speaker system, 549 00:25:59,850 --> 00:26:02,600 if the resident is unable to speak really loudly, 550 00:26:02,600 --> 00:26:06,640 or, in Margaret's case, she once pulling out a chest of drawers 551 00:26:06,640 --> 00:26:07,830 and it fell on her. 552 00:26:07,830 --> 00:26:10,620 So she was unable to both reach the call light system. 553 00:26:10,620 --> 00:26:12,590 And if she had, she wouldn't have 554 00:26:12,590 --> 00:26:17,026 been able to speak loud enough for the nurse to hear her. 555 00:26:17,026 --> 00:26:18,650 And actually, to add to that, so that's 556 00:26:18,650 --> 00:26:20,233 the reason why we're planning on using 557 00:26:20,233 --> 00:26:21,790 an iPad for this solution. 558 00:26:21,790 --> 00:26:23,640 So we're planning on creating application, 559 00:26:23,640 --> 00:26:25,970 because Margaret always has her iPod with her, 560 00:26:25,970 --> 00:26:28,020 such that she can just press a couple of buttons 561 00:26:28,020 --> 00:26:29,895 and be able to talk with the nurses directly. 562 00:26:32,012 --> 00:26:34,470 LAURA D'AQUILA: So to talk more about assistive technology, 563 00:26:34,470 --> 00:26:36,810 both what Margaret herself uses and what 564 00:26:36,810 --> 00:26:39,171 other residents at The Boston Home use, 565 00:26:39,171 --> 00:26:40,920 Margaret, along with many other residents, 566 00:26:40,920 --> 00:26:43,860 uses a motorized wheelchair to get around. 567 00:26:43,860 --> 00:26:45,610 And Margaret is very tech savvy. 568 00:26:45,610 --> 00:26:48,130 She owns both an iPad and an iPhone, 569 00:26:48,130 --> 00:26:49,650 which she always has with her. 570 00:26:49,650 --> 00:26:52,520 And she owns a special stylus so that she's actually 571 00:26:52,520 --> 00:26:57,710 able to use her iPad and reach all ends of the screen. 572 00:26:57,710 --> 00:27:00,530 And they've come in handy in emergency situations. 573 00:27:00,530 --> 00:27:03,710 Tanya mentioned the time when the drawer fell on Margaret 574 00:27:03,710 --> 00:27:07,300 and she was unable to reach the existing call light system 575 00:27:07,300 --> 00:27:07,830 button. 576 00:27:07,830 --> 00:27:09,890 But fortunately, because she had her iPhone, 577 00:27:09,890 --> 00:27:13,060 she was able to call for help that way. 578 00:27:13,060 --> 00:27:16,040 And the Tanya had mentioned that Margaret is an artist, 579 00:27:16,040 --> 00:27:18,630 and she's able to use a mouthpiece 580 00:27:18,630 --> 00:27:21,540 to hold her paintbrush, and that's something 581 00:27:21,540 --> 00:27:23,520 that Don had designed for her. 582 00:27:23,520 --> 00:27:25,700 And along with other residents in the home, 583 00:27:25,700 --> 00:27:29,070 Margaret has the call light system button in her bedroom 584 00:27:29,070 --> 00:27:31,740 and also in the bathroom. 585 00:27:31,740 --> 00:27:36,020 So thanks to much of Don's work, The Boston Home is very open 586 00:27:36,020 --> 00:27:37,660 to assistive technology, and it's 587 00:27:37,660 --> 00:27:40,190 very prevalent within the home now. 588 00:27:40,190 --> 00:27:43,740 For example, there exists a cyber cafe, where resonance 589 00:27:43,740 --> 00:27:47,710 are able to use computers, and both the keyboards and mice 590 00:27:47,710 --> 00:27:51,000 within the cyber cafe are accessible to the needs 591 00:27:51,000 --> 00:27:56,000 of the residents with their limited arm mobility. 592 00:27:56,000 --> 00:27:59,150 And there are also speech therapists and occupational 593 00:27:59,150 --> 00:28:03,690 therapists on site, and these individuals use technology, 594 00:28:03,690 --> 00:28:06,560 such as iPads, in order to assess 595 00:28:06,560 --> 00:28:09,510 the progress of the residents. 596 00:28:09,510 --> 00:28:12,597 And Don has added many features to wheelchairs 597 00:28:12,597 --> 00:28:14,430 throughout his time their too, accommodating 598 00:28:14,430 --> 00:28:15,971 the different needs of the residents. 599 00:28:19,370 --> 00:28:22,460 TANYA TALKAR: So to assess how this application is going 600 00:28:22,460 --> 00:28:25,086 to work for Margaret and for the residents, because her vision 601 00:28:25,086 --> 00:28:26,460 is that at the end of this, we'll 602 00:28:26,460 --> 00:28:29,670 be able to have all 35 residents who are using iPads 603 00:28:29,670 --> 00:28:31,390 also use the system. 604 00:28:31,390 --> 00:28:32,990 We have a couple of success metrics. 605 00:28:32,990 --> 00:28:35,150 They're mostly qualitative. 606 00:28:35,150 --> 00:28:36,620 So, one, we just want to make sure 607 00:28:36,620 --> 00:28:38,703 that the correct iPad is being called and answered 608 00:28:38,703 --> 00:28:41,940 and that the correct resident is getting aid. 609 00:28:41,940 --> 00:28:44,490 We will also want to time the amount of time 610 00:28:44,490 --> 00:28:46,390 that it takes for a task to be completed. 611 00:28:46,390 --> 00:28:49,660 So suppose Margaret needs a refill of water, 612 00:28:49,660 --> 00:28:52,030 so the nurse will come in with the call light system, 613 00:28:52,030 --> 00:28:55,160 get the request, and then go back to get the water. 614 00:28:55,160 --> 00:28:59,430 versus if we have this on the iPad application, how much time 615 00:28:59,430 --> 00:29:00,320 that'll take. 616 00:29:00,320 --> 00:29:04,370 And then just success overall-- does this application actually 617 00:29:04,370 --> 00:29:06,670 integrate into the current system with the nurses? 618 00:29:06,670 --> 00:29:08,800 Will the nurses actually end up using the system? 619 00:29:08,800 --> 00:29:11,310 Will the residents actually end up using the system as well? 620 00:29:15,409 --> 00:29:16,950 LAURA D'AQUILA: So a few weeks ago we 621 00:29:16,950 --> 00:29:20,434 started discussing with Margaret potential solutions 622 00:29:20,434 --> 00:29:21,100 to this problem. 623 00:29:21,100 --> 00:29:23,660 Tanya had mentioned that we're going to be using an iPad. 624 00:29:23,660 --> 00:29:26,770 We work with Margaret to get her input and her feedback 625 00:29:26,770 --> 00:29:29,440 to actually develop some early sketches of what 626 00:29:29,440 --> 00:29:31,270 her end of this app looked like. 627 00:29:31,270 --> 00:29:33,390 And then within the next week, we 628 00:29:33,390 --> 00:29:36,320 developed this into a low fidelity iOS app, 629 00:29:36,320 --> 00:29:38,250 which I'll walk through now. 630 00:29:38,250 --> 00:29:40,630 So this is the home screen of the app 631 00:29:40,630 --> 00:29:42,970 that Margaret is going to have access to. 632 00:29:42,970 --> 00:29:45,060 It has two large by things that are 633 00:29:45,060 --> 00:29:48,930 color-coded red and black, for urgent and non-urgent requests. 634 00:29:48,930 --> 00:29:51,400 And should Margaret press Non-Urgent Request, 635 00:29:51,400 --> 00:29:56,040 she's taken to the next screen, which 636 00:29:56,040 --> 00:30:01,930 has six potentially customizable buttons for a common requests 637 00:30:01,930 --> 00:30:04,760 that Margaret may have for the nurse. 638 00:30:04,760 --> 00:30:06,960 For example, if she needs a cup of water 639 00:30:06,960 --> 00:30:09,330 or if she wants a nurse to come to a room, 640 00:30:09,330 --> 00:30:12,980 if she wants to be able to video conference with a nurse, 641 00:30:12,980 --> 00:30:14,700 these are all buttons that are easily 642 00:30:14,700 --> 00:30:16,550 accessible for her to press. 643 00:30:16,550 --> 00:30:20,580 And similarly, if Margaret presses the Urgent button, 644 00:30:20,580 --> 00:30:24,330 she's taken directly into a video call with a nurse. 645 00:30:24,330 --> 00:30:26,990 And at the bottom, there is a Cancel Call button for her 646 00:30:26,990 --> 00:30:30,279 to cancel in the event that she inadvertently 647 00:30:30,279 --> 00:30:31,070 pressed the button. 648 00:30:33,820 --> 00:30:36,130 TANYA TALKAR: So amazingly enough, 649 00:30:36,130 --> 00:30:39,090 right after we transferred this application to her iPad, 650 00:30:39,090 --> 00:30:40,810 she immediately went off to go talk 651 00:30:40,810 --> 00:30:43,268 to some of the other residents about the application, which 652 00:30:43,268 --> 00:30:44,150 is great. 653 00:30:44,150 --> 00:30:46,680 And so some of the feedback that she came up with 654 00:30:46,680 --> 00:30:48,980 was that she wanted to make sure that the buttons were 655 00:30:48,980 --> 00:30:52,380 large enough, in case residents end up having some fatigue 656 00:30:52,380 --> 00:30:54,710 and their fingers start dragging on the iPad. 657 00:30:54,710 --> 00:30:58,120 So she uses a stylus, but not all of the residents do. 658 00:30:58,120 --> 00:31:00,770 So we just make sure that we have larger buttons for this. 659 00:31:00,770 --> 00:31:02,940 She also wanted to make sure that there was 660 00:31:02,940 --> 00:31:04,660 an option to type in messages. 661 00:31:04,660 --> 00:31:07,940 So suppose any of the requests that a resident 662 00:31:07,940 --> 00:31:11,095 has isn't on the screen with six buttons, 663 00:31:11,095 --> 00:31:13,345 that they will be able to type in their own customized 664 00:31:13,345 --> 00:31:14,405 request. 665 00:31:14,405 --> 00:31:16,280 She also wants to make sure that she's always 666 00:31:16,280 --> 00:31:18,870 talking with the nurse through a video call 667 00:31:18,870 --> 00:31:21,700 because sometimes her message or what she wants 668 00:31:21,700 --> 00:31:24,020 isn't conveyed through text. 669 00:31:24,020 --> 00:31:26,940 And something that all of the residents said they wanted 670 00:31:26,940 --> 00:31:29,400 was that the application be voice-activated 671 00:31:29,400 --> 00:31:31,180 because not all of them are able to press 672 00:31:31,180 --> 00:31:34,270 the buttons at every time, and that they'll 673 00:31:34,270 --> 00:31:40,380 be able to go forward with this if they 674 00:31:40,380 --> 00:31:41,980 can't speak super well either. 675 00:31:46,089 --> 00:31:47,880 LAURA D'AQUILA: So in addition to Margaret, 676 00:31:47,880 --> 00:31:50,520 because of the nature of the system that we're building, 677 00:31:50,520 --> 00:31:52,420 we actually have an additional client, 678 00:31:52,420 --> 00:31:54,870 and that's the nurse on the other end of the system 679 00:31:54,870 --> 00:31:56,840 that Margaret's trying to reach. 680 00:31:56,840 --> 00:31:59,880 So we had mentioned all of these nice features 681 00:31:59,880 --> 00:32:02,720 that we want the app to have, for example, video chat. 682 00:32:02,720 --> 00:32:06,000 And none of this stuff is feasible with the existing 683 00:32:06,000 --> 00:32:09,200 call light system that exists already within the home. 684 00:32:09,200 --> 00:32:13,970 So because of that, we're hoping to bypass the existing 685 00:32:13,970 --> 00:32:17,630 system altogether and have the nurse on the other end 686 00:32:17,630 --> 00:32:20,290 have an iPad or a computer screen 687 00:32:20,290 --> 00:32:23,170 as well with an instance of this app running 688 00:32:23,170 --> 00:32:25,980 so that she can receive the requests from Margaret 689 00:32:25,980 --> 00:32:26,920 on this app. 690 00:32:26,920 --> 00:32:30,430 So because of this, we've had to speak with and work 691 00:32:30,430 --> 00:32:32,310 with Angela, who, as Tanya mentioned, 692 00:32:32,310 --> 00:32:35,990 is the nurse on the first floor, which is Margaret's floor, so 693 00:32:35,990 --> 00:32:38,870 that we can make sure that we can accommodate her needs. 694 00:32:38,870 --> 00:32:41,430 In addition to Margaret's needs in terms of what 695 00:32:41,430 --> 00:32:43,180 this application should have. 696 00:32:43,180 --> 00:32:45,970 And we've also worked with Don to make sure 697 00:32:45,970 --> 00:32:49,890 that this app is feasible to be adopted within the nurse's 698 00:32:49,890 --> 00:32:50,660 station. 699 00:32:50,660 --> 00:32:52,370 And within the next few weeks, we're 700 00:32:52,370 --> 00:32:57,390 also going to work on speaking with other management level 701 00:32:57,390 --> 00:32:59,270 people within The Boston Home to make sure 702 00:32:59,270 --> 00:33:03,080 that we're able to get their go-to as well. 703 00:33:03,080 --> 00:33:05,940 And one potential thing that we're still discussing 704 00:33:05,940 --> 00:33:12,260 is how to acquire a potential iPad that the nurse would 705 00:33:12,260 --> 00:33:13,094 need at her station. 706 00:33:13,094 --> 00:33:15,510 So we're looking into whether this is something The Boston 707 00:33:15,510 --> 00:33:17,450 Home would purchase, or whether it's something 708 00:33:17,450 --> 00:33:19,840 that we may need to get with our own team budget. 709 00:33:22,360 --> 00:33:25,710 So in terms of the timeline, we spent the first month speaking 710 00:33:25,710 --> 00:33:28,460 with Margaret, getting to know her, her needs, 711 00:33:28,460 --> 00:33:31,380 and what she's looking for in a potential solution. 712 00:33:31,380 --> 00:33:34,225 And then in October, we were able to assess 713 00:33:34,225 --> 00:33:35,980 in greater detail the feasibility 714 00:33:35,980 --> 00:33:39,270 of an iPad-based solution on both ends. 715 00:33:39,270 --> 00:33:40,970 We worked with Margaret and Angela. 716 00:33:40,970 --> 00:33:43,710 We developed a low fidelity prototypes for Margaret 717 00:33:43,710 --> 00:33:46,960 and tested this out and received feedback. 718 00:33:46,960 --> 00:33:49,710 And then in November, our plans include 719 00:33:49,710 --> 00:33:52,590 developing a low fidelity prototypes for Angela, 720 00:33:52,590 --> 00:33:55,619 for the nurses' side of the nurse call system. 721 00:33:55,619 --> 00:33:57,160 We hope to receive feedback from that 722 00:33:57,160 --> 00:33:59,510 and iterate through those prototypes as well. 723 00:33:59,510 --> 00:34:02,270 We also want to work on the back end of actually sending 724 00:34:02,270 --> 00:34:06,430 requests from Margaret's iPad to the nurses' iPads. 725 00:34:06,430 --> 00:34:09,810 And we want to get video conferencing set up 726 00:34:09,810 --> 00:34:11,090 the week after that. 727 00:34:11,090 --> 00:34:13,205 And then finally, hopefully by the end of November 728 00:34:13,205 --> 00:34:14,790 or beginning of December, we'll have 729 00:34:14,790 --> 00:34:17,310 an app that's able to be used within the home 730 00:34:17,310 --> 00:34:20,330 by not only Margaret, but potentially other residents 731 00:34:20,330 --> 00:34:23,489 in the home as well, and we can continue to test it out and get 732 00:34:23,489 --> 00:34:24,354 feedback from them. 733 00:34:27,855 --> 00:34:29,480 TANYA TALKAR: So a little bit about how 734 00:34:29,480 --> 00:34:32,360 the logistics for this project go-- our meetings are 735 00:34:32,360 --> 00:34:33,364 pretty conversational. 736 00:34:33,364 --> 00:34:35,030 They're less like an interview, and more 737 00:34:35,030 --> 00:34:38,760 just us talking with Margaret, Angela, Don. 738 00:34:38,760 --> 00:34:41,699 So Laura is mostly in charge of the videos and pictures, 739 00:34:41,699 --> 00:34:44,250 and then Beth and I are the ones who are taking notes, 740 00:34:44,250 --> 00:34:46,270 asking the questions. 741 00:34:46,270 --> 00:34:51,790 And we meet before the meetings to go over speaking notes 742 00:34:51,790 --> 00:34:53,810 and go over an agenda of what exactly 743 00:34:53,810 --> 00:34:57,130 we want to be accomplished during the meeting. 744 00:34:57,130 --> 00:35:00,370 As for division of work for the application itself, all of us 745 00:35:00,370 --> 00:35:02,410 are new to iOS development. 746 00:35:02,410 --> 00:35:04,120 So we're learning all of this together. 747 00:35:04,120 --> 00:35:06,244 We're planning on mostly working on the application 748 00:35:06,244 --> 00:35:08,650 as a team, all three of us together. 749 00:35:08,650 --> 00:35:10,840 And then for other things, Beth and Laura mainly 750 00:35:10,840 --> 00:35:14,069 worked on the video, and I was mostly in charge of the report 751 00:35:14,069 --> 00:35:16,110 and the presentation for the mid-semester panels. 752 00:35:21,019 --> 00:35:22,560 LAURA D'AQUILA: So to conclude, we're 753 00:35:22,560 --> 00:35:25,287 very excited to be working on this project with Margaret 754 00:35:25,287 --> 00:35:25,870 this semester. 755 00:35:25,870 --> 00:35:28,460 It's been a lot of fun so far, and it's exciting to us 756 00:35:28,460 --> 00:35:30,570 that this is something that could potentially not 757 00:35:30,570 --> 00:35:32,390 only benefit Margaret, but could also 758 00:35:32,390 --> 00:35:35,530 benefit many other residents of The Boston Home, 759 00:35:35,530 --> 00:35:37,640 should this be more universally adopted. 760 00:35:48,386 --> 00:35:49,760 PROFESSOR 2: So one of the things 761 00:35:49,760 --> 00:35:51,400 that you guys mentioned at the beginning, 762 00:35:51,400 --> 00:35:53,150 as you were talking about the call system, 763 00:35:53,150 --> 00:35:55,940 was some of the regulations that are in place at the home. 764 00:35:55,940 --> 00:35:59,270 Can you talk about how your system actually 765 00:35:59,270 --> 00:36:01,550 can map to some of those regulations, 766 00:36:01,550 --> 00:36:06,110 and if they have to change in any way to use your system? 767 00:36:08,294 --> 00:36:10,460 TANYA TALKAR: So that was actually one of the things 768 00:36:10,460 --> 00:36:13,043 that we are considering when we were thinking about whether we 769 00:36:13,043 --> 00:36:15,830 wanted to interface with the current call light system, 770 00:36:15,830 --> 00:36:18,539 or whether we would create this separate iPad application. 771 00:36:18,539 --> 00:36:20,080 And that's also one of things we need 772 00:36:20,080 --> 00:36:22,490 to talk with for administration. 773 00:36:22,490 --> 00:36:27,190 We believe that due to this being a separate application, 774 00:36:27,190 --> 00:36:30,450 we shouldn't need to have the nurses go in 775 00:36:30,450 --> 00:36:34,290 and turn off anything on the iPad, which 776 00:36:34,290 --> 00:36:38,140 is what they need to currently do with the call light system. 777 00:36:38,140 --> 00:36:40,570 And that's something that the company themselves 778 00:36:40,570 --> 00:36:42,490 had come up with as a regulation, that it 779 00:36:42,490 --> 00:36:44,700 would have to be turned off by a nurse aide. 780 00:36:44,700 --> 00:36:48,630 But for this, because it's the resident who's in charge of it, 781 00:36:48,630 --> 00:36:50,810 and they'll be video calling with the nurse, 782 00:36:50,810 --> 00:36:52,561 we believe that it shouldn't be a problem. 783 00:36:52,561 --> 00:36:54,560 PROFESSOR 2: So I guess my question is, how does 784 00:36:54,560 --> 00:36:55,880 that regulation actually map? 785 00:36:55,880 --> 00:36:58,710 So not the fact that the system requires it, 786 00:36:58,710 --> 00:37:00,720 but what is the kind of the purpose of having 787 00:37:00,720 --> 00:37:02,244 that regulation requirement, and is 788 00:37:02,244 --> 00:37:04,410 it something that you guys should be matching or not 789 00:37:04,410 --> 00:37:05,280 matching? 790 00:37:05,280 --> 00:37:07,210 It's an open question. 791 00:37:07,210 --> 00:37:10,260 Is there a benefit to having the nurse specifically 792 00:37:10,260 --> 00:37:12,750 go there and turn off, and did they 793 00:37:12,750 --> 00:37:15,122 design that into the system not because it 794 00:37:15,122 --> 00:37:16,830 was needed for the system, but because it 795 00:37:16,830 --> 00:37:20,010 was important for the task? 796 00:37:20,010 --> 00:37:22,774 TANYA TALKAR: So we've asked everyone about that. 797 00:37:22,774 --> 00:37:24,440 They haven't really been able to come up 798 00:37:24,440 --> 00:37:27,550 with an answer for that. 799 00:37:27,550 --> 00:37:30,410 Margaret herself kind of finds it intrusive 800 00:37:30,410 --> 00:37:33,090 that you have to come in and turn off the light manually, 801 00:37:33,090 --> 00:37:36,650 instead of her just being able to turn it off. 802 00:37:36,650 --> 00:37:39,310 So, yeah, we're not really completely sure 803 00:37:39,310 --> 00:37:42,194 why that is there. 804 00:37:42,194 --> 00:37:44,360 We just know that it's a regulation on the company's 805 00:37:44,360 --> 00:37:46,580 part. 806 00:37:46,580 --> 00:37:50,700 PROFESSOR 3: Well, it's clearly a Department of Public Health 807 00:37:50,700 --> 00:37:54,740 regulation, and it evolved out of abuse and neglect issues, 808 00:37:54,740 --> 00:38:00,210 where you could respond to a resident 809 00:38:00,210 --> 00:38:03,670 or just repeatedly shut their call request off, 810 00:38:03,670 --> 00:38:05,340 without really addressing a need. 811 00:38:05,340 --> 00:38:12,180 But skirting DPH-- sometimes you sort of 812 00:38:12,180 --> 00:38:15,170 have to play the game a little bit. 813 00:38:15,170 --> 00:38:20,430 So if it's an experimental or a redundant system, 814 00:38:20,430 --> 00:38:22,880 it may not have to match their regulations 815 00:38:22,880 --> 00:38:29,900 as long as the primary one meets those specific requirements 816 00:38:29,900 --> 00:38:36,730 of having someone go to attend to them. 817 00:38:36,730 --> 00:38:44,150 But I am curious how you honed in on that specific approach 818 00:38:44,150 --> 00:38:49,130 that you've taken of using the iPad and using that simple GUI, 819 00:38:49,130 --> 00:38:52,385 versus some of the ideas I had pitched initially. 820 00:38:54,607 --> 00:38:56,690 TANYA TALKAR: So I think I was mostly through just 821 00:38:56,690 --> 00:38:58,020 talking to Margaret. 822 00:38:58,020 --> 00:39:03,200 And her approach to this was that if she was in a situation 823 00:39:03,200 --> 00:39:05,780 where she wasn't able to reach the call light system, 824 00:39:05,780 --> 00:39:11,940 her immediate thought would be to use her iPhone 825 00:39:11,940 --> 00:39:13,740 and call The Boston Home and try and reach 826 00:39:13,740 --> 00:39:15,055 the nurses through that. 827 00:39:15,055 --> 00:39:18,960 And so we felt that that would be a little easier to interface 828 00:39:18,960 --> 00:39:21,630 in that way, in terms of she always has her iPad 829 00:39:21,630 --> 00:39:23,790 or her iPhone with her. 830 00:39:23,790 --> 00:39:27,890 And so suppose there were connectivity issues in terms 831 00:39:27,890 --> 00:39:31,667 of like we weren't unable to reach the-- suppose 832 00:39:31,667 --> 00:39:34,250 there was like a Bluetooth that was attached to the call light 833 00:39:34,250 --> 00:39:38,410 system, if that connectivity wasn't established and wasn't 834 00:39:38,410 --> 00:39:40,310 stable, then that would be an issue, 835 00:39:40,310 --> 00:39:42,730 as opposed to having Wi-Fi, which I think 836 00:39:42,730 --> 00:39:45,653 would be more reliable within the home and slightly 837 00:39:45,653 --> 00:39:46,819 outside of the home as well. 838 00:39:47,145 --> 00:39:47,895 PROFESSOR 3: Good. 839 00:39:53,550 --> 00:39:57,400 PROFESSOR 1: What I would ask is how much function does Margaret 840 00:39:57,400 --> 00:39:59,090 herself actually have? 841 00:39:59,090 --> 00:40:01,190 It's clear that you're trying to broaden 842 00:40:01,190 --> 00:40:03,700 this other members of The Boston Home, which is great, 843 00:40:03,700 --> 00:40:07,960 but what can Margaret herself do with an iPad app, 844 00:40:07,960 --> 00:40:11,550 and have you measured that, or have you observed 845 00:40:11,550 --> 00:40:14,920 her use of the prototype? 846 00:40:14,920 --> 00:40:19,230 LAURA D'AQUILA: So Margaret has limited use of her arms, 847 00:40:19,230 --> 00:40:22,160 and it varies depending on how tired she is. 848 00:40:22,160 --> 00:40:24,050 So when she's particularly fatigued, 849 00:40:24,050 --> 00:40:30,530 it's even harder for her to reach the full screen 850 00:40:30,530 --> 00:40:32,160 coverage of the iPad. 851 00:40:32,160 --> 00:40:35,180 But because of the fact that she has a stylus that definitely 852 00:40:35,180 --> 00:40:37,150 helps, but that's also part of the reason 853 00:40:37,150 --> 00:40:41,650 why we had looked into adding the large buttons 854 00:40:41,650 --> 00:40:45,980 so that it's more feasible for Margaret and other residents 855 00:40:45,980 --> 00:40:51,940 to be able to use all of these functionalities of the app. 856 00:40:51,940 --> 00:40:54,650 But, yeah, she can move her arms a little bit, but not very 857 00:40:54,650 --> 00:40:55,480 much. 858 00:40:55,480 --> 00:40:58,110 Tanya had mentioned that on the first day we met with her, 859 00:40:58,110 --> 00:41:04,900 we needed her to sign a contract for our team contract, 860 00:41:04,900 --> 00:41:07,380 and it was clearly a struggle for her 861 00:41:07,380 --> 00:41:10,590 to be able to move her arms to sign the document. 862 00:41:10,590 --> 00:41:13,920 When she paints, she uses a mouthpiece 863 00:41:13,920 --> 00:41:15,970 so that she can do it that way. 864 00:41:15,970 --> 00:41:25,080 So I'd say that her arm movement is pretty limited, 865 00:41:25,080 --> 00:41:29,040 but because of the stylus, she's able to at least get 866 00:41:29,040 --> 00:41:29,787 by with the iPad. 867 00:41:32,591 --> 00:41:34,757 PROFESSOR 2: We can probably take another one or two 868 00:41:34,757 --> 00:41:37,242 questions if anyone has comments. 869 00:41:43,206 --> 00:41:45,691 AUDIENCE: I have a question. 870 00:41:45,691 --> 00:41:48,673 You talked about there was that situation when someone fell 871 00:41:48,673 --> 00:41:50,164 over and was stuck in a ditch. 872 00:41:50,164 --> 00:41:55,850 How could they access this application in the iPad? 873 00:41:55,850 --> 00:41:57,215 Are you considering [INAUDIBLE]? 874 00:41:59,890 --> 00:42:01,630 LAURA D'AQUILA: Right, so maybe depending 875 00:42:01,630 --> 00:42:04,760 on the exact situation, they personally may not 876 00:42:04,760 --> 00:42:06,120 be able to use this app. 877 00:42:06,120 --> 00:42:08,130 But in the event that maybe there's 878 00:42:08,130 --> 00:42:09,935 another resident who's also outside, 879 00:42:09,935 --> 00:42:13,240 it may be a little bit easier for that second resident 880 00:42:13,240 --> 00:42:16,090 to call for help while they're still outside, as opposed 881 00:42:16,090 --> 00:42:18,200 to having to go into the building 882 00:42:18,200 --> 00:42:21,305 to alert the nurses of what had happened. 883 00:42:21,305 --> 00:42:22,680 But, yeah, in the event that it's 884 00:42:22,680 --> 00:42:28,860 just one person outside and depending on the situation, 885 00:42:28,860 --> 00:42:31,470 if they're not able to use the iPad, like if it fell 886 00:42:31,470 --> 00:42:34,005 or something, then I guess it wouldn't help them. 887 00:42:34,005 --> 00:42:35,380 But it's more so in the situation 888 00:42:35,380 --> 00:42:36,630 where there's multiple people. 889 00:42:39,386 --> 00:42:40,969 AUDIENCE: I thought it was interesting 890 00:42:40,969 --> 00:42:43,915 that you had identified the nurses as your second client. 891 00:42:43,915 --> 00:42:46,870 It's very smart of you to do that. 892 00:42:46,870 --> 00:42:51,699 How many signals are they being bombarded by on an average day, 893 00:42:51,699 --> 00:42:58,327 and how is that going to affect how you would get 894 00:42:58,327 --> 00:43:01,630 their attention [INAUDIBLE]? 895 00:43:01,630 --> 00:43:03,780 TANYA TALKAR: So Angela currently just 896 00:43:03,780 --> 00:43:07,500 has the nurse call system plus a computer set up at the desk. 897 00:43:07,500 --> 00:43:09,360 And then, of course, if there any nurses 898 00:43:09,360 --> 00:43:11,060 who are coming up to her to talk, 899 00:43:11,060 --> 00:43:12,900 that will be a distraction as well. 900 00:43:12,900 --> 00:43:14,910 So that was one of the primary things 901 00:43:14,910 --> 00:43:18,460 that we wanted to address with her when we talked to her. 902 00:43:18,460 --> 00:43:20,960 So that's why we're wondering, should it be on the computer, 903 00:43:20,960 --> 00:43:22,540 or should it be on a separate iPad? 904 00:43:22,540 --> 00:43:25,380 And she did tell us that with all the signals 905 00:43:25,380 --> 00:43:27,410 that she's getting, if it was on the computer, 906 00:43:27,410 --> 00:43:30,470 she would not be looking at it because you'll be most probably 907 00:43:30,470 --> 00:43:34,340 browsing other applications, if it's email or whatever. 908 00:43:34,340 --> 00:43:36,290 And then with the call light system, 909 00:43:36,290 --> 00:43:39,620 that is also something that beeps whenever someone calls 910 00:43:39,620 --> 00:43:40,840 in, so she will address that. 911 00:43:40,840 --> 00:43:42,600 But if there is an iPad just mounted 912 00:43:42,600 --> 00:43:44,480 like right in the middle there, she'll 913 00:43:44,480 --> 00:43:47,260 be able to see that as a notification coming in. 914 00:43:47,260 --> 00:43:50,490 And she said that because of where 915 00:43:50,490 --> 00:43:53,310 she is sitting at the desk, then she'll be able to see that. 916 00:43:59,706 --> 00:44:01,674 AUDIENCE: I just had a question. 917 00:44:01,674 --> 00:44:04,872 I noticed I didn't hear anything about what 918 00:44:04,872 --> 00:44:08,070 was the client [INAUDIBLE] nurse [INAUDIBLE] 919 00:44:08,070 --> 00:44:11,514 in terms of the [? hybrid ?] liability of this application. 920 00:44:11,514 --> 00:44:14,466 Have you guys considered putting that into your metric 921 00:44:14,466 --> 00:44:16,450 as well for success? 922 00:44:16,450 --> 00:44:19,240 Like what does she expect to work 923 00:44:19,240 --> 00:44:22,120 90% of the time, 80% of the time? 924 00:44:22,120 --> 00:44:26,100 And also, what [INAUDIBLE]? 925 00:44:26,100 --> 00:44:27,974 You know, complicated systems are complicated 926 00:44:27,974 --> 00:44:31,646 for a reason Maybe that's something-- like have you 927 00:44:31,646 --> 00:44:33,770 guys had a conversation with the client about this? 928 00:44:37,496 --> 00:44:39,370 LAURA D'AQUILA: We haven't had a conversation 929 00:44:39,370 --> 00:44:42,060 about a specific number, but one of the benefits 930 00:44:42,060 --> 00:44:45,820 to the fact that we have this iPad system on top 931 00:44:45,820 --> 00:44:49,680 of the existing system is that in the event that Wi-Fi goes 932 00:44:49,680 --> 00:44:51,390 out or something like that in the home, 933 00:44:51,390 --> 00:44:54,730 and the iPad app that isn't working, 934 00:44:54,730 --> 00:44:57,090 then Margaret does have the ability 935 00:44:57,090 --> 00:45:01,540 to simply use the system that's in place, which I think 936 00:45:01,540 --> 00:45:05,970 is known to at least go through to the nurse pretty reliably, 937 00:45:05,970 --> 00:45:08,740 if not receive a response all the time. 938 00:45:08,740 --> 00:45:11,240 PROFESSOR 2: All right, let's have Team [? Aaron ?] come up. 939 00:45:20,070 --> 00:45:21,840 PHILIP: So hello, everyone. 940 00:45:21,840 --> 00:45:23,400 We're Team Kate. 941 00:45:23,400 --> 00:45:24,979 My name is Philip [INAUDIBLE]. 942 00:45:24,979 --> 00:45:26,104 And my teammates here are-- 943 00:45:26,104 --> 00:45:28,096 JENNY: Jenny. 944 00:45:28,096 --> 00:45:30,090 RAQUEL: Hi, I'm Raquel. 945 00:45:30,090 --> 00:45:32,751 [? PHILIP: So ?] today we're just going to talk about 946 00:45:32,751 --> 00:45:35,250 the progress that we've made over the course of the last few 947 00:45:35,250 --> 00:45:37,760 weeks in our project with Kate. 948 00:45:37,760 --> 00:45:41,090 Let me quickly introduce who our client is. 949 00:45:41,090 --> 00:45:44,070 Over the last few weeks, we've been talking about Kate. 950 00:45:44,070 --> 00:45:47,130 She's our client, and she works at the Cambridge Disabilities 951 00:45:47,130 --> 00:45:48,400 Commission. 952 00:45:48,400 --> 00:45:52,680 She has profound hearing loss, and wears a cochlear implant. 953 00:45:52,680 --> 00:45:55,740 We also have this really short video, about two minutes long, 954 00:45:55,740 --> 00:45:58,250 in which talks about herself and a little bit more 955 00:45:58,250 --> 00:46:00,340 about the hearing impairment that she has. 956 00:46:00,340 --> 00:46:03,322 [VIDEO PLAYBACK] 957 00:46:08,800 --> 00:46:11,790 -Without my cochlear implants, I have no residual hearing 958 00:46:11,790 --> 00:46:15,940 at all, so that would be considered profound. 959 00:46:15,940 --> 00:46:21,106 With my cochlear implants, I have a mild to moderate hearing 960 00:46:21,106 --> 00:46:21,605 loss. 961 00:46:21,605 --> 00:46:24,360 But obviously, I do really well with my implants. 962 00:46:24,360 --> 00:46:25,940 You through in any background noise, 963 00:46:25,940 --> 00:46:27,870 and it's just you can forget about it. 964 00:46:27,870 --> 00:46:29,360 In this kind of setting I do really 965 00:46:29,360 --> 00:46:30,651 well with my cochlear implants. 966 00:46:35,970 --> 00:46:38,875 So I was born with a very mild hearing loss. 967 00:46:38,875 --> 00:46:41,360 I just had like preferential seating in school. 968 00:46:41,360 --> 00:46:44,110 And it became profound or rapidly progressive 969 00:46:44,110 --> 00:46:46,080 when I was 13. 970 00:46:46,080 --> 00:46:50,230 It went from mild to moderate to severe and then to profound. 971 00:46:50,230 --> 00:46:54,210 I got my first cochlear implant my left side in 1999. 972 00:46:54,210 --> 00:47:03,230 I had my right side done in 2008, so nine years later. 973 00:47:03,230 --> 00:47:06,020 It is not a quick fix. 974 00:47:06,020 --> 00:47:08,314 So when it was first turned on, everything, 975 00:47:08,314 --> 00:47:10,230 like my brother's would like stomp their feet, 976 00:47:10,230 --> 00:47:12,604 and it would sound like someone was ringing little bells. 977 00:47:12,604 --> 00:47:13,370 It was weird. 978 00:47:13,370 --> 00:47:15,790 And I couldn't understand any speech, 979 00:47:15,790 --> 00:47:18,780 but I had to force myself to turn my hearing aid off 980 00:47:18,780 --> 00:47:19,960 on the right side. 981 00:47:19,960 --> 00:47:25,200 And I was home from college for six or seven weeks. 982 00:47:25,200 --> 00:47:28,970 and I did all these listening exercises with my family. 983 00:47:28,970 --> 00:47:30,150 We made it a game. 984 00:47:30,150 --> 00:47:32,220 Like my mom would take children's books. 985 00:47:32,220 --> 00:47:34,950 And at first, she would read them aloud, 986 00:47:34,950 --> 00:47:36,970 and I would follow along, trying to place what 987 00:47:36,970 --> 00:47:38,421 I was hearing with the words. 988 00:47:38,421 --> 00:47:39,920 And then I would graduate from that, 989 00:47:39,920 --> 00:47:43,009 and I wasn't allowed to follow along-- to read along. 990 00:47:43,009 --> 00:47:44,550 and I was trying to follow the story, 991 00:47:44,550 --> 00:47:47,060 just basically training my brain. 992 00:47:47,060 --> 00:47:51,560 So my brain was receiving the signal in a slightly new way. 993 00:47:51,560 --> 00:47:53,580 And so I basically had to retrain my brain 994 00:47:53,580 --> 00:47:56,420 how to take that signal and interpret it into usable sound. 995 00:48:00,560 --> 00:48:02,630 I mean, I can't tell you how much 996 00:48:02,630 --> 00:48:03,990 it has changed my life though. 997 00:48:03,990 --> 00:48:05,800 Like I used to walk around college 998 00:48:05,800 --> 00:48:09,130 with a little whiteboard, and people would write notes to me. 999 00:48:09,130 --> 00:48:13,670 It has completely changed my life-- completely. 1000 00:48:13,670 --> 00:48:14,650 So for me. 1001 00:48:14,650 --> 00:48:16,880 It was so worth it. 1002 00:48:20,608 --> 00:48:24,427 [END PLAYBACK] 1003 00:48:24,427 --> 00:48:26,260 PHILIP: So we've already seen from the video 1004 00:48:26,260 --> 00:48:27,990 that Katie uses cochlear implants, 1005 00:48:27,990 --> 00:48:31,490 and on this I would just like to mention 1006 00:48:31,490 --> 00:48:34,420 that a lot of people who have hearing impediments 1007 00:48:34,420 --> 00:48:39,650 still have functional nerve ending, the auditory nerves. 1008 00:48:39,650 --> 00:48:42,104 The main problem is just that the part 1009 00:48:42,104 --> 00:48:44,860 of the ear that is responsible for transmitting 1010 00:48:44,860 --> 00:48:49,160 sound to an electric signals that are translated 1011 00:48:49,160 --> 00:48:52,000 by the brain aren't functional. 1012 00:48:52,000 --> 00:48:55,700 So it is that part of the ear that the cochlear implant 1013 00:48:55,700 --> 00:48:57,905 tries to fix. 1014 00:48:57,905 --> 00:48:59,280 So the cochlear implant basically 1015 00:48:59,280 --> 00:49:01,390 provides a new channel through which sound 1016 00:49:01,390 --> 00:49:05,400 signals can be transmitted to electrical signals 1017 00:49:05,400 --> 00:49:07,840 for the brain to interpret. 1018 00:49:07,840 --> 00:49:10,300 RAQUEL: So now we can get into a little bit of what 1019 00:49:10,300 --> 00:49:13,200 our goals is a Team Kate. 1020 00:49:13,200 --> 00:49:16,370 So our major goal here is to create cochlear implant 1021 00:49:16,370 --> 00:49:19,990 attachments, so whether it's covers or clip-on add-ons 1022 00:49:19,990 --> 00:49:23,740 to her cochlear implant to kind of hit on three 1023 00:49:23,740 --> 00:49:26,950 particular sub-goals in this. 1024 00:49:26,950 --> 00:49:29,580 So the first is to provide some water resistance 1025 00:49:29,580 --> 00:49:30,210 to her implant. 1026 00:49:30,210 --> 00:49:32,210 So currently, it isn't water resistant, 1027 00:49:32,210 --> 00:49:35,940 and she doesn't have a cover that she uses for that. 1028 00:49:35,940 --> 00:49:39,260 So to give some context for that desire 1029 00:49:39,260 --> 00:49:41,990 is that she, just like any of us, 1030 00:49:41,990 --> 00:49:44,930 often finds ourselves in the rain. 1031 00:49:44,930 --> 00:49:46,970 It seems like it's a great day to begin with, 1032 00:49:46,970 --> 00:49:49,290 and by the end of day, it's pouring. 1033 00:49:49,290 --> 00:49:51,890 So for Kate that means walking around with her hands 1034 00:49:51,890 --> 00:49:53,650 like this, covering her implants, 1035 00:49:53,650 --> 00:49:55,900 or taking off her implants entirely, 1036 00:49:55,900 --> 00:50:00,810 and that's not ideal because she can no longer hear. 1037 00:50:00,810 --> 00:50:03,300 A second goal for our implant covers 1038 00:50:03,300 --> 00:50:06,850 are to provide some sort of sound blocking. 1039 00:50:06,850 --> 00:50:11,820 So Kate has issues in noisy environments. 1040 00:50:11,820 --> 00:50:15,192 And what I mean by this is like in a lobby or a restaurant 1041 00:50:15,192 --> 00:50:17,400 where there's just lots of background noise going on, 1042 00:50:17,400 --> 00:50:19,260 she has problems distinguishing sounds 1043 00:50:19,260 --> 00:50:21,804 that are coming from behind her from sounds that are 1044 00:50:21,804 --> 00:50:22,970 coming from in front of her. 1045 00:50:22,970 --> 00:50:25,019 So she's having a conversation with somebody. 1046 00:50:25,019 --> 00:50:26,560 It's hard to actually comprehend what 1047 00:50:26,560 --> 00:50:29,450 they're saying when there's lots of noise from behind. 1048 00:50:29,450 --> 00:50:32,460 And currently, her implant just has a single microphone 1049 00:50:32,460 --> 00:50:34,840 so there's no kind of sound directionality 1050 00:50:34,840 --> 00:50:36,380 capability to it. 1051 00:50:36,380 --> 00:50:38,850 And so an idea for this is just provide 1052 00:50:38,850 --> 00:50:41,360 some sort of physical barrier to basically block sound 1053 00:50:41,360 --> 00:50:43,820 from behind her. 1054 00:50:43,820 --> 00:50:45,440 The third thing here is attachedness. 1055 00:50:45,440 --> 00:50:48,770 So she has a problem with her cochlear implants 1056 00:50:48,770 --> 00:50:52,280 just falling off all the time for different reasons. 1057 00:50:52,280 --> 00:50:55,766 But one goal for us is to try to just provide 1058 00:50:55,766 --> 00:50:57,890 something that gives it a little bit more stability 1059 00:50:57,890 --> 00:51:00,650 so it just stays on her head more. 1060 00:51:00,650 --> 00:51:02,820 So the context of that one in particular 1061 00:51:02,820 --> 00:51:05,520 is really just any place, any time. 1062 00:51:05,520 --> 00:51:07,390 The context for all of these are kind 1063 00:51:07,390 --> 00:51:09,790 of just very portable things that she 1064 00:51:09,790 --> 00:51:11,410 can use in her everyday life. 1065 00:51:15,590 --> 00:51:17,730 So we've come up with a few success metrics. 1066 00:51:17,730 --> 00:51:21,680 We haven't formally tested these yet. 1067 00:51:21,680 --> 00:51:23,280 But for the water resistance goal 1068 00:51:23,280 --> 00:51:25,600 here, we'll be doing something like a water bead test 1069 00:51:25,600 --> 00:51:28,660 for the material to make sure that it's water resistant. 1070 00:51:31,540 --> 00:51:33,650 I guess I should say that Kate has gotten 1071 00:51:33,650 --> 00:51:37,150 a demo of her cochlear implant from the company that 1072 00:51:37,150 --> 00:51:40,290 makes her implants, so we can do these water resistance tests 1073 00:51:40,290 --> 00:51:42,120 not on her actual implant. 1074 00:51:42,120 --> 00:51:45,090 But something like putting a material, like a paper towel 1075 00:51:45,090 --> 00:51:47,650 or something that would show wetness, around the implant, 1076 00:51:47,650 --> 00:51:49,760 putting on her cover, spraying it, and looking 1077 00:51:49,760 --> 00:51:52,990 for signs of wetness and where that wetness is coming in. 1078 00:51:52,990 --> 00:51:54,710 Sound blocking, what we plan to do 1079 00:51:54,710 --> 00:51:58,070 is kind of a human subject experiment with her. 1080 00:51:58,070 --> 00:52:01,910 So what we'll do is play noise, a noisy environment behind her 1081 00:52:01,910 --> 00:52:04,440 from different audio clips. 1082 00:52:04,440 --> 00:52:06,450 and then have audio clips in front of her 1083 00:52:06,450 --> 00:52:09,000 of speech or just a conversation, 1084 00:52:09,000 --> 00:52:11,290 and try to kind of get her subjective feedback, 1085 00:52:11,290 --> 00:52:15,280 and identify her threshold for the volume of that conversation 1086 00:52:15,280 --> 00:52:17,370 in front of her, and when she recognize that 1087 00:52:17,370 --> 00:52:20,609 with and without our different sound-blocking devices. 1088 00:52:20,609 --> 00:52:22,400 And then attachedness-- so currently, we've 1089 00:52:22,400 --> 00:52:25,510 talked to Kate, and her cochlear implants can fall out 1090 00:52:25,510 --> 00:52:29,230 up to 10 or 12 times a day, and this isn't even necessarily 1091 00:52:29,230 --> 00:52:31,220 when she's being particularly active. 1092 00:52:31,220 --> 00:52:33,930 So our goal is something less than three time a day, 1093 00:52:33,930 --> 00:52:36,096 just something more reasonable for her to deal with. 1094 00:52:43,690 --> 00:52:46,310 JENNY: So during our design process, we talked to Kate, 1095 00:52:46,310 --> 00:52:49,030 and he's really, really excited about this project 1096 00:52:49,030 --> 00:52:52,380 because it has been a problem for her for a very long time, 1097 00:52:52,380 --> 00:52:56,040 and she showed us a bunch of her existing solutions she has. 1098 00:52:56,040 --> 00:52:59,190 She had a head band that you could hook the implants into, 1099 00:52:59,190 --> 00:53:00,890 and that would keep them in place. 1100 00:53:00,890 --> 00:53:02,840 But it's very sporty. 1101 00:53:02,840 --> 00:53:06,057 It's a bright colored headband, and it wasn't something 1102 00:53:06,057 --> 00:53:07,140 that she was pleased with. 1103 00:53:07,140 --> 00:53:12,280 And then she also had some other kind of neoprene sleeves 1104 00:53:12,280 --> 00:53:15,850 that she could put over her implants, 1105 00:53:15,850 --> 00:53:20,920 but these technologies were all like pretty primitive, 1106 00:53:20,920 --> 00:53:27,500 and they only served to solve one problem at once. 1107 00:53:27,500 --> 00:53:32,970 So through talking to her, we identified a bunch of feature 1108 00:53:32,970 --> 00:53:34,810 that we wanted to address, the three 1109 00:53:34,810 --> 00:53:37,260 features-- the water resistance, sound blocking, 1110 00:53:37,260 --> 00:53:40,400 and attachedness-- and we began prototyping. 1111 00:53:40,400 --> 00:53:44,270 So we each individually sketched designs 1112 00:53:44,270 --> 00:53:47,126 so we could come up with many ideas when we came together. 1113 00:53:47,126 --> 00:53:52,200 And as a team we chose the few to prototype out. 1114 00:53:52,200 --> 00:53:54,410 And I'll show that on the next slide. 1115 00:53:54,410 --> 00:53:59,730 But we used [INAUDIBLE], which were two materials that we 1116 00:53:59,730 --> 00:54:01,590 discovered during lecture. 1117 00:54:01,590 --> 00:54:05,310 And then last week we presented the prototypes to Kate 1118 00:54:05,310 --> 00:54:08,410 and did some informal testing. 1119 00:54:08,410 --> 00:54:10,380 And she was pretty impressed them, 1120 00:54:10,380 --> 00:54:16,220 and that leads me to the next slide of what we made so far. 1121 00:54:16,220 --> 00:54:19,190 So at the beginning, we wanted to create 1122 00:54:19,190 --> 00:54:22,310 some sort of all-on-one attachment 1123 00:54:22,310 --> 00:54:25,340 that would address all three of the problems. 1124 00:54:25,340 --> 00:54:33,090 So on the left, you can see it's like a unibody cover that 1125 00:54:33,090 --> 00:54:34,900 covers the entire implant that also 1126 00:54:34,900 --> 00:54:39,250 provides a hood over the microphone at the very top. 1127 00:54:39,250 --> 00:54:41,950 And then there's also a little ear bud 1128 00:54:41,950 --> 00:54:44,730 that would help with the attachments. 1129 00:54:44,730 --> 00:54:48,670 We decide not to go with that because Kate wanted something 1130 00:54:48,670 --> 00:54:51,530 a little more modular, something that she could just 1131 00:54:51,530 --> 00:54:56,560 have separate accessories for each problem. 1132 00:54:56,560 --> 00:55:03,270 So when we prototyped keeping this in mind, 1133 00:55:03,270 --> 00:55:05,700 we created separate covers. 1134 00:55:05,700 --> 00:55:08,990 So the left of the top right photo 1135 00:55:08,990 --> 00:55:12,040 are covers for the coil and the implant 1136 00:55:12,040 --> 00:55:15,050 itself, the device with processor. 1137 00:55:15,050 --> 00:55:19,130 And then we also created some sort of hood 1138 00:55:19,130 --> 00:55:22,510 that you can put right over the microphone, which 1139 00:55:22,510 --> 00:55:25,402 it's a little hard to tell, but the microphone right here. 1140 00:55:25,402 --> 00:55:27,110 So this hood, it provides a small barrier 1141 00:55:27,110 --> 00:55:34,240 from the sound traveling from behind to hit the microphone. 1142 00:55:34,240 --> 00:55:42,875 So we tried this out and then also compared 1143 00:55:42,875 --> 00:55:49,040 it to these previously existing devices. 1144 00:55:49,040 --> 00:55:54,470 They're called Ear Glasses, and these help also 1145 00:55:54,470 --> 00:55:58,710 amplify sound that's coming toward you. 1146 00:55:58,710 --> 00:56:01,940 And she was pretty pleased with them. 1147 00:56:01,940 --> 00:56:04,630 And this was like very informal, so we 1148 00:56:04,630 --> 00:56:08,890 plan to continue to prototype and iterate our design 1149 00:56:08,890 --> 00:56:11,640 and then bring something to show her on Thursday. 1150 00:56:16,562 --> 00:56:18,020 For the rest of the semester, we're 1151 00:56:18,020 --> 00:56:23,760 looking to continue measuring and testing out our success 1152 00:56:23,760 --> 00:56:27,090 metrics with the prototypes that we're planning to build. 1153 00:56:27,090 --> 00:56:28,940 And then in November, we hope to finalize 1154 00:56:28,940 --> 00:56:30,565 the design and the materials that we're 1155 00:56:30,565 --> 00:56:35,390 going to use and then create our final deliverable. 1156 00:56:35,390 --> 00:56:37,660 We're looking, like materials wise, 1157 00:56:37,660 --> 00:56:40,010 we're keeping 3D printing in mind 1158 00:56:40,010 --> 00:56:43,180 to actually create the attachments. 1159 00:56:43,180 --> 00:56:47,583 But we haven't finalized it yet, so that's just something 1160 00:56:47,583 --> 00:56:48,764 that we're looking at ahead. 1161 00:56:48,764 --> 00:56:51,425 And that concludes our presentation. 1162 00:56:51,425 --> 00:56:53,091 Thank you, and we'll take any questions. 1163 00:57:04,540 --> 00:57:07,090 PROFESSOR 1: First, that was a really nice video explaining 1164 00:57:07,090 --> 00:57:10,590 her story with getting the cochlear implants 1165 00:57:10,590 --> 00:57:13,320 and what kind of change they've made in her life. 1166 00:57:13,320 --> 00:57:17,070 I'm curious about a couple of other aspects of your client 1167 00:57:17,070 --> 00:57:19,795 that you alluded to a little bit, 1168 00:57:19,795 --> 00:57:21,870 but I was wondering how important they are. 1169 00:57:21,870 --> 00:57:26,940 First, how active or athletic is she, and is it important to her 1170 00:57:26,940 --> 00:57:30,820 that these things be really, really secure? 1171 00:57:30,820 --> 00:57:33,636 And second, how sensitive is she to her appearance? 1172 00:57:37,450 --> 00:57:40,232 RAQUEL: So she's not particularly active. 1173 00:57:40,232 --> 00:57:41,690 What she did tell us is that she'll 1174 00:57:41,690 --> 00:57:44,610 starting pool therapy soon for another condition 1175 00:57:44,610 --> 00:57:47,650 that she has that we didn't talk about here, 1176 00:57:47,650 --> 00:57:50,420 but that she'll be using the headband because it's 1177 00:57:50,420 --> 00:57:52,530 really important that they don't fall off at all. 1178 00:57:52,530 --> 00:57:55,060 And she'll be in shallow end and there will basically 1179 00:57:55,060 --> 00:57:56,490 be no water touching them. 1180 00:57:56,490 --> 00:57:59,050 But so for these it's really just kind of daily life. 1181 00:57:59,050 --> 00:58:00,380 She works in an office. 1182 00:58:00,380 --> 00:58:02,940 She attends a lot of meetings. 1183 00:58:02,940 --> 00:58:03,960 So nothing too active. 1184 00:58:03,960 --> 00:58:06,010 She does ride her bike every once in awhile, 1185 00:58:06,010 --> 00:58:07,968 and she has issues when she puts on her helmet. 1186 00:58:07,968 --> 00:58:09,720 But again, she uses that headband 1187 00:58:09,720 --> 00:58:14,330 that just really keeps it secure on her head for those purposes. 1188 00:58:14,330 --> 00:58:18,020 And about her caring about what she looks like, we actually 1189 00:58:18,020 --> 00:58:20,442 did ask her straight up, how do you feel 1190 00:58:20,442 --> 00:58:21,650 about looking a little silly? 1191 00:58:21,650 --> 00:58:22,790 Is that OK? 1192 00:58:22,790 --> 00:58:26,820 And she said that's fine. 1193 00:58:26,820 --> 00:58:28,020 I think there's a fine line. 1194 00:58:28,020 --> 00:58:32,430 We don't want something that's crazy sticking out. 1195 00:58:32,430 --> 00:58:35,560 But I think she's willing to have a little bit of something 1196 00:58:35,560 --> 00:58:36,330 extra on her head. 1197 00:58:36,330 --> 00:58:38,640 She's even told us that she prefers it 1198 00:58:38,640 --> 00:58:41,260 when people can see that she has a cochlear implant, instead 1199 00:58:41,260 --> 00:58:45,860 of covering it up so that they automatically know that she has 1200 00:58:45,860 --> 00:58:48,806 hearing loss so that they can communicate better with her 1201 00:58:48,806 --> 00:58:50,472 from the beginning of talking with them. 1202 00:58:53,294 --> 00:58:55,460 PROFESSOR 2: So I'm wondering if you could talk more 1203 00:58:55,460 --> 00:58:57,710 about that design shape. 1204 00:58:57,710 --> 00:59:00,470 So you had the kind of Ear Glasses 1205 00:59:00,470 --> 00:59:03,440 as something that was clearly doing something similar that 1206 00:59:03,440 --> 00:59:05,810 provides that directionality. 1207 00:59:05,810 --> 00:59:08,920 And in your design, you showed kind of two different methods 1208 00:59:08,920 --> 00:59:12,180 of a different shape that was on that hood for how 1209 00:59:12,180 --> 00:59:13,767 you're doing that. 1210 00:59:13,767 --> 00:59:15,850 I'm wondering-- I know you said you guys are still 1211 00:59:15,850 --> 00:59:18,520 kind of the middle of testing and testing out of it. 1212 00:59:18,520 --> 00:59:24,940 How is that shape playing into your kind of design decisions? 1213 00:59:24,940 --> 00:59:27,580 Are you are you specifically designing shapes and testing 1214 00:59:27,580 --> 00:59:29,440 them, or is that more aesthetic? 1215 00:59:32,967 --> 00:59:34,550 JENNY: To be honest, we haven't tested 1216 00:59:34,550 --> 00:59:36,810 that many shapes out yet. 1217 00:59:36,810 --> 00:59:39,250 I think that when we do create a lot shapes, 1218 00:59:39,250 --> 00:59:41,760 we're going to look at effectiveness 1219 00:59:41,760 --> 00:59:43,092 before aesthetics. 1220 00:59:46,700 --> 00:59:49,880 And we tried out different sizes so far, 1221 00:59:49,880 --> 00:59:52,314 or we tried out three different sizes 1222 00:59:52,314 --> 00:59:58,788 so far of the sound blocking piece, 1223 00:59:58,788 --> 01:00:01,776 and definitely the largest one actually 1224 01:00:01,776 --> 01:00:03,270 works the most effectively. 1225 01:00:03,270 --> 01:00:07,752 So we're going to find a balance between portability 1226 01:00:07,752 --> 01:00:10,242 and effectiveness. 1227 01:00:13,667 --> 01:00:15,750 PROFESSOR 3: Any questions from the audience here? 1228 01:00:15,750 --> 01:00:17,291 If we can have the last team as well. 1229 01:00:17,291 --> 01:00:21,314 Jeffrey, [INAUDIBLE] and get set up as well. 1230 01:00:21,314 --> 01:00:23,456 Any other questions or comments? 1231 01:00:23,456 --> 01:00:25,706 AUDIENCE: How are the ear glasses supposed to stay on? 1232 01:00:30,952 --> 01:00:32,618 JENNY: As advertised, they were supposed 1233 01:00:32,618 --> 01:00:34,076 to have some sort of adhesive strip 1234 01:00:34,076 --> 01:00:36,794 that you can just pull off and then stick on. 1235 01:00:36,794 --> 01:00:40,314 But they don't actually do that. 1236 01:00:40,314 --> 01:00:41,730 It didn't actually come with that, 1237 01:00:41,730 --> 01:00:43,650 so they just sit on your ear. 1238 01:00:43,650 --> 01:00:45,570 But when we had her try them on, we just 1239 01:00:45,570 --> 01:00:47,970 wanted her to try it on for the shape of the ear glasses. 1240 01:00:47,970 --> 01:00:51,378 And she was really impressed by how big of a difference 1241 01:00:51,378 --> 01:00:52,866 it made with her microphone. 1242 01:00:52,866 --> 01:00:54,241 RAQUEL: But these, in particular, 1243 01:00:54,241 --> 01:00:56,834 won't stay on very well for us, and they definitely 1244 01:00:56,834 --> 01:00:58,500 don't stay on with her cochlear implant. 1245 01:01:01,190 --> 01:01:03,760 PROFESSOR 3: I assume that magnets would 1246 01:01:03,760 --> 01:01:05,860 be a problem with the implants. 1247 01:01:05,860 --> 01:01:08,090 I don't know if you address that specifically. 1248 01:01:08,090 --> 01:01:13,960 I'm just thinking of how well devices click in place. 1249 01:01:13,960 --> 01:01:16,913 I'm just thinking quick one in the extruder head 1250 01:01:16,913 --> 01:01:20,070 on the 3D printer, how would you just get sort of lined up, 1251 01:01:20,070 --> 01:01:21,630 and it jumps into place. 1252 01:01:21,630 --> 01:01:24,680 And I like that functionality, but I'm 1253 01:01:24,680 --> 01:01:26,480 wondering-- I'm assuming-- that that would 1254 01:01:26,480 --> 01:01:27,688 be problem with the implants. 1255 01:01:30,742 --> 01:01:33,200 PHILIP: It's actually one of the things that we considered. 1256 01:01:33,200 --> 01:01:35,410 But just like you said, we weren't 1257 01:01:35,410 --> 01:01:37,460 sure about how adding a magnet to the system 1258 01:01:37,460 --> 01:01:40,635 would affect the way the outer part 1259 01:01:40,635 --> 01:01:44,872 of the implanted part of it. 1260 01:01:44,872 --> 01:01:46,580 So we haven't really tried that yet here. 1261 01:01:46,580 --> 01:01:49,270 But I think we're going to explore that option 1262 01:01:49,270 --> 01:01:54,520 a little bit more and see how it affects the communication. 1263 01:01:54,520 --> 01:01:56,270 If it doesn't have that much of an impact, 1264 01:01:56,270 --> 01:01:58,560 then we would use it. 1265 01:02:00,189 --> 01:02:02,480 PROFESSOR 3: Any final questions or anything like that? 1266 01:02:06,890 --> 01:02:09,340 AUDIENCE: One quick thing is you may [INAUDIBLE] 1267 01:02:09,340 --> 01:02:13,126 think about the shape, the engineering of it. 1268 01:02:13,126 --> 01:02:15,292 There's some principles to apply to kind of engineer 1269 01:02:15,292 --> 01:02:21,002 a shape that is most effective for sound filtering 1270 01:02:21,002 --> 01:02:21,792 or sound blocking. 1271 01:02:21,792 --> 01:02:22,740 That kind of thing. 1272 01:02:22,740 --> 01:02:24,180 OK, Thank you. 1273 01:02:30,360 --> 01:02:31,790 Hi, so we're Team Jeffery. 1274 01:02:33,164 --> 01:02:34,080 JODIE CHEN: I'm Jodie. 1275 01:02:34,303 --> 01:02:35,136 DAVID KE: I'm David. 1276 01:02:37,220 --> 01:02:39,045 JODIE CHEN: And our client is Jeffrey. 1277 01:02:39,045 --> 01:02:42,910 Here's a picture of him, and he's blind. 1278 01:02:42,910 --> 01:02:45,290 So first, we're going to talk about contextual inquiry 1279 01:02:45,290 --> 01:02:47,670 and how we worked with the HAAT model. 1280 01:02:47,670 --> 01:02:49,790 So we came up with a few questions 1281 01:02:49,790 --> 01:02:51,770 that we planned on asking him to kind of get 1282 01:02:51,770 --> 01:02:53,909 an idea of what activities he enjoys doing 1283 01:02:53,909 --> 01:02:55,700 and which activities we can help streamline 1284 01:02:55,700 --> 01:03:00,125 or make more efficient and allow him to, I guess, enjoy it more. 1285 01:03:00,125 --> 01:03:01,500 So we kind of asked him questions 1286 01:03:01,500 --> 01:03:02,874 like, what activities do you want 1287 01:03:02,874 --> 01:03:04,300 to be able to do independently? 1288 01:03:04,300 --> 01:03:07,290 And we asked him to show as an activity 1289 01:03:07,290 --> 01:03:09,620 that he enjoyed in his free time and also like 1290 01:03:09,620 --> 01:03:11,550 how he uses computers, because it turns out 1291 01:03:11,550 --> 01:03:13,930 that he uses computers a lot. 1292 01:03:13,930 --> 01:03:16,550 So I think one thing that we found 1293 01:03:16,550 --> 01:03:20,360 about Jeffrey is that he's actually extremely independent, 1294 01:03:20,360 --> 01:03:21,860 even though he's blind. 1295 01:03:21,860 --> 01:03:24,070 He told us that like 75% of blind people 1296 01:03:24,070 --> 01:03:27,275 are like unemployed, but he's been employed 1297 01:03:27,275 --> 01:03:29,530 in multiple places before, and he also continues 1298 01:03:29,530 --> 01:03:30,920 to do a lot of financial work. 1299 01:03:30,920 --> 01:03:34,740 So we have a video to kind of show, I guess, 1300 01:03:34,740 --> 01:03:38,735 how he's l challenged our misconceptions. 1301 01:03:38,735 --> 01:03:43,082 [VIDEO PLAYBACK] 1302 01:03:44,060 --> 01:03:46,360 -Hi, so I'm David, and I'm part of Team Jeffrey 1303 01:03:46,360 --> 01:03:48,350 with Jodie Chen and Yi Tong. 1304 01:03:48,350 --> 01:03:50,726 And the client that we're working with for PPAT, his name 1305 01:03:50,726 --> 01:03:53,050 is Jeffrey, and he's blind. 1306 01:03:53,050 --> 01:03:55,379 I guess initially going into this project, 1307 01:03:55,379 --> 01:03:57,920 I didn't really know what I was expecting in terms of working 1308 01:03:57,920 --> 01:04:00,340 with a person with blindness. 1309 01:04:00,340 --> 01:04:02,560 I guess, part of it's like I didn't expect them 1310 01:04:02,560 --> 01:04:04,300 to be super self-sufficient. 1311 01:04:04,300 --> 01:04:06,000 And I thought they would have to be 1312 01:04:06,000 --> 01:04:09,042 relying on a lot of technologies to go through their day. 1313 01:04:09,042 --> 01:04:11,500 [? And so I was like ?] struggle with like a decent portion 1314 01:04:11,500 --> 01:04:14,255 of the daily activities. 1315 01:04:14,255 --> 01:04:16,630 -I guess something that really surprised me about Jeffrey 1316 01:04:16,630 --> 01:04:21,016 was how autonomous he is in like his travel and other stuff. 1317 01:04:21,016 --> 01:04:22,976 So what you might not know about Jeffrey 1318 01:04:22,976 --> 01:04:26,752 is that during our Monday and Wednesday classes sessions as 1319 01:04:26,752 --> 01:04:29,924 well as class labs, he actually comes over 1320 01:04:29,924 --> 01:04:33,828 and he listens and he also participates in our team 1321 01:04:33,828 --> 01:04:36,065 discussions, gives all of like helpful advice 1322 01:04:36,065 --> 01:04:40,340 as to like how do we really work on the project 1323 01:04:40,340 --> 01:04:41,300 and how to build it. 1324 01:04:41,300 --> 01:04:44,172 -So I have plan A, plan B, plan C, 1325 01:04:44,172 --> 01:05:05,760 and plan D. That's how you have to live OK, so here we're 1326 01:05:05,760 --> 01:05:07,810 on my email. 1327 01:05:07,810 --> 01:05:11,650 -Jeffrey is-- you can barely tell Jeffrey's blind 1328 01:05:11,650 --> 01:05:14,954 when he's at his place because he knows 1329 01:05:14,954 --> 01:05:17,822 exactly where everything is. 1330 01:05:17,822 --> 01:05:20,605 He's really passionate about technology. 1331 01:05:20,605 --> 01:05:21,646 -He is really passionate. 1332 01:05:21,646 --> 01:05:23,396 He told me that he as the coolest gadgets. 1333 01:05:23,396 --> 01:05:24,270 -[INAUDIBLE]? 1334 01:05:24,270 --> 01:05:24,861 -What toys? 1335 01:05:24,861 --> 01:05:27,360 -You looked at this other wall while you were sitting there. 1336 01:05:27,360 --> 01:05:28,721 I said, Jeff, what is it? 1337 01:05:28,721 --> 01:05:29,304 -I don't know. 1338 01:05:29,304 --> 01:05:31,248 -Remember, I said when I got here 1339 01:05:31,248 --> 01:05:33,690 and he had this-- it's a talking thermometer. 1340 01:05:33,690 --> 01:05:39,140 -Oh, it's a talking thermometer, indoor/outdoor temperature. 1341 01:05:39,140 --> 01:05:42,445 Neil plays with it more than I do because, frankly, I 1342 01:05:42,445 --> 01:05:44,127 don't give a damn. 1343 01:05:44,127 --> 01:05:45,210 It's too much information. 1344 01:05:49,422 --> 01:05:54,810 -The indoor temperature is 68.3 degrees Fahrenheit. 1345 01:05:54,810 --> 01:05:56,450 -I don't even know how accurate it is. 1346 01:05:56,450 --> 01:05:58,920 It's a toy. 1347 01:05:58,920 --> 01:06:01,840 -And then he [? bought ?] this when he started cooking. 1348 01:06:01,840 --> 01:06:05,110 It's a talking kitchen thermometer-- a kitchen scale. 1349 01:06:05,110 --> 01:06:09,320 -Oh, yeah, I tell you, he knows more the toys-- I forgot. 1350 01:06:09,320 --> 01:06:11,546 -Because I found them. 1351 01:06:11,546 --> 01:06:12,524 -(SINGING) Ah-- 1352 01:06:12,524 --> 01:06:13,491 -Ah. 1353 01:06:13,491 --> 01:06:13,991 -Ah. 1354 01:06:18,890 --> 01:06:20,122 [END PLAYBACK] 1355 01:06:20,122 --> 01:06:22,330 JODIE CHEN: So here's some information about Jeffrey. 1356 01:06:22,330 --> 01:06:24,540 So Jeffrey, he's visually impaired, 1357 01:06:24,540 --> 01:06:27,800 and he has been kind of for his whole life. 1358 01:06:27,800 --> 01:06:30,432 He used to be able to see like different things 1359 01:06:30,432 --> 01:06:32,640 if you blew them up really large on like a projector. 1360 01:06:32,640 --> 01:06:36,260 But now, all he can see is like just like light and darkness. 1361 01:06:36,260 --> 01:06:38,790 So he's used computers for practically his whole, 1362 01:06:38,790 --> 01:06:41,372 so he's actually very, very good at using his JAWS screen 1363 01:06:41,372 --> 01:06:42,080 reading software. 1364 01:06:42,080 --> 01:06:44,260 And he actually teaches people how 1365 01:06:44,260 --> 01:06:46,650 to use it in the Carroll Center for the Blind. 1366 01:06:46,650 --> 01:06:49,030 And he also knows braille, and he told us 1367 01:06:49,030 --> 01:06:50,550 that actually a lot of blind people 1368 01:06:50,550 --> 01:06:52,190 don't know how to read braille, so he's actually 1369 01:06:52,190 --> 01:06:53,648 one of the few people that actually 1370 01:06:53,648 --> 01:06:55,870 does know how to read braille. 1371 01:06:55,870 --> 01:06:57,900 And he also does a lot of financial paperwork 1372 01:06:57,900 --> 01:07:01,560 for his homeowner's association for his condo, 1373 01:07:01,560 --> 01:07:03,850 and he does a lot of taxes for his friends. 1374 01:07:03,850 --> 01:07:05,870 So he's constantly on his computer, 1375 01:07:05,870 --> 01:07:09,105 checking his email, using Excel to work on that. 1376 01:07:11,960 --> 01:07:15,310 So we kind of wanted to narrow down like an activity 1377 01:07:15,310 --> 01:07:18,160 that Jeffrey has to do that he wants, I guess, like more help 1378 01:07:18,160 --> 01:07:18,660 in. 1379 01:07:18,660 --> 01:07:22,252 So he's a pretty opinionated person, 1380 01:07:22,252 --> 01:07:24,460 so he already had an idea of what problems he exactly 1381 01:07:24,460 --> 01:07:26,310 wanted us to solve and also solutions 1382 01:07:26,310 --> 01:07:28,270 as to how to solve them. 1383 01:07:28,270 --> 01:07:30,740 So on the activities that he kind of narrowed down 1384 01:07:30,740 --> 01:07:34,890 for us is finding a way to sign a paper with a wet ink 1385 01:07:34,890 --> 01:07:35,530 signature. 1386 01:07:35,530 --> 01:07:39,330 So he gets a lot of financial sheets and documents from banks 1387 01:07:39,330 --> 01:07:42,010 and stuff that need him to sign the document 1388 01:07:42,010 --> 01:07:44,220 and not have a digital signature. 1389 01:07:44,220 --> 01:07:45,725 So in order to sign a document, he 1390 01:07:45,725 --> 01:07:47,910 has to have his visual aide Neil come over 1391 01:07:47,910 --> 01:07:51,290 and like help him find the exact line where he has to sign. 1392 01:07:51,290 --> 01:07:52,880 And if he doesn't have a visual aide, 1393 01:07:52,880 --> 01:07:55,310 then there's no way for him to get that done. 1394 01:07:55,310 --> 01:07:57,340 And she also uses Excel a lot, and he 1395 01:07:57,340 --> 01:07:59,220 doesn't like the new format of Excel, 1396 01:07:59,220 --> 01:08:01,320 so he wants us to kind of like change 1397 01:08:01,320 --> 01:08:03,420 it to be more compatible with like the versions 1398 01:08:03,420 --> 01:08:04,850 that he's used to. 1399 01:08:04,850 --> 01:08:08,980 So we narrowed it down to being able to help 1400 01:08:08,980 --> 01:08:12,880 him sign a document when he's like independent and alone, 1401 01:08:12,880 --> 01:08:15,050 without a visual aide to help him. 1402 01:08:15,050 --> 01:08:21,069 So to kind of get a better idea of what we have to work with, 1403 01:08:21,069 --> 01:08:23,319 we kind of asked him like, what assistive technologies 1404 01:08:23,319 --> 01:08:26,100 that he currently use so to find out 1405 01:08:26,100 --> 01:08:28,550 which assistive technologies that he was comfortable with. 1406 01:08:28,550 --> 01:08:32,390 So he told us that he's really comfortable with JAWS, 1407 01:08:32,390 --> 01:08:37,000 and that like when he does OCR on a document, 1408 01:08:37,000 --> 01:08:40,810 he can determine where a signature line is because JAWS 1409 01:08:40,810 --> 01:08:43,970 will just say like, underscore, underscore, underscore. 1410 01:08:43,970 --> 01:08:47,359 So all we had to do is kind of find a way 1411 01:08:47,359 --> 01:08:49,850 to guide like his mouse pointer to like 1412 01:08:49,850 --> 01:08:53,290 the position of the underline and then 1413 01:08:53,290 --> 01:08:55,551 to find a way to convert that into like something 1414 01:08:55,551 --> 01:08:57,509 that could be translated onto a piece of paper. 1415 01:09:01,010 --> 01:09:05,160 So for our success metrics we kind of wanted 1416 01:09:05,160 --> 01:09:07,470 to be able to evaluate like how well he 1417 01:09:07,470 --> 01:09:11,029 can sign a document by seeing if he can actually find the place 1418 01:09:11,029 --> 01:09:13,460 where to sign independently on his own, 1419 01:09:13,460 --> 01:09:16,069 which he isn't able to do right now. 1420 01:09:16,069 --> 01:09:18,330 And we also wanted to measure like how long it takes 1421 01:09:18,330 --> 01:09:20,090 for him to measure a document. 1422 01:09:20,090 --> 01:09:22,210 And I guess that's pretty easy to improve on 1423 01:09:22,210 --> 01:09:24,662 because currently it takes infinite time for him to sign 1424 01:09:24,662 --> 01:09:25,750 a document. 1425 01:09:25,750 --> 01:09:27,220 And we also wanted to measure kind 1426 01:09:27,220 --> 01:09:29,910 of how accurate he is with finding the position 1427 01:09:29,910 --> 01:09:32,200 and also signing because we don't 1428 01:09:32,200 --> 01:09:33,850 want him to sign somewhere that's 1429 01:09:33,850 --> 01:09:36,160 really far away from the line. 1430 01:09:36,160 --> 01:09:38,284 So that's kind of like the scope. 1431 01:09:38,284 --> 01:09:39,700 YI TONG: So I'm just going to talk 1432 01:09:39,700 --> 01:09:41,866 about the project organization, the progress so far. 1433 01:09:45,620 --> 01:09:47,193 So the first is the ideation. 1434 01:09:47,193 --> 01:09:49,359 So we're very lucky, so Jeffrey's always in the lab, 1435 01:09:49,359 --> 01:09:50,830 as you all can see. 1436 01:09:50,830 --> 01:09:52,790 So he's been meeting with us every lab 1437 01:09:52,790 --> 01:09:55,000 and also contributes a lot of good ideas. 1438 01:09:55,000 --> 01:09:58,590 So we go to the lab with ideas and then consult Jeffrey 1439 01:09:58,590 --> 01:09:59,870 and ask him for the feedback. 1440 01:09:59,870 --> 01:10:01,520 And then we narrow down the solutions 1441 01:10:01,520 --> 01:10:02,970 after every discussion. 1442 01:10:02,970 --> 01:10:06,750 And then finally, we decided on the mechi and software 1443 01:10:06,750 --> 01:10:09,820 combined solution. 1444 01:10:09,820 --> 01:10:12,410 So for the software part, so we all 1445 01:10:12,410 --> 01:10:14,730 know that JAWS can detect a signature line 1446 01:10:14,730 --> 01:10:17,540 and read out underscore and also like signatures 1447 01:10:17,540 --> 01:10:18,860 and different kinds of words. 1448 01:10:18,860 --> 01:10:21,485 So we just need to find a way to get coordinates from the mouse 1449 01:10:21,485 --> 01:10:24,360 location, and then take in the mouse location two inches so 1450 01:10:24,360 --> 01:10:27,970 that that can be the input for the mechi part. 1451 01:10:27,970 --> 01:10:30,350 So for mechanical part, we need a frame 1452 01:10:30,350 --> 01:10:33,270 the holds standard sized paper so it won't slide away. 1453 01:10:33,270 --> 01:10:35,790 And then we need sliding braille rulers, or rails, 1454 01:10:35,790 --> 01:10:40,310 to move horizontally and vertically so that Jeffrey can 1455 01:10:40,310 --> 01:10:42,900 adjust to the exacty x-, y-coordinates by sliding 1456 01:10:42,900 --> 01:10:45,150 the two rails. 1457 01:10:45,150 --> 01:10:47,600 So here's the early sketches and also the prototype 1458 01:10:47,600 --> 01:10:48,570 that we have. 1459 01:10:48,570 --> 01:10:51,520 So on the right is just some white board drawings 1460 01:10:51,520 --> 01:10:53,850 about different ideas that we had before. 1461 01:10:53,850 --> 01:10:56,690 So the first one you can say something more or less like 1462 01:10:56,690 --> 01:11:00,680 the magnifier that we see on [? Ability ?] [? Expo ?]. 1463 01:11:00,680 --> 01:11:03,430 So basically the advantage of that is he 1464 01:11:03,430 --> 01:11:07,390 doesn't have any restriction while he's signing things. 1465 01:11:07,390 --> 01:11:10,080 But that is really hard to implement because the camera's 1466 01:11:10,080 --> 01:11:12,420 on top of the paper. 1467 01:11:12,420 --> 01:11:17,040 And also we also get inspired by the idea of a project built 1468 01:11:17,040 --> 01:11:18,780 by an MIT Media Lab. 1469 01:11:18,780 --> 01:11:22,175 So it's a finger reader, so like whenever he scans a line, 1470 01:11:22,175 --> 01:11:23,050 he hears "signature." 1471 01:11:23,050 --> 01:11:24,720 Then he will start signing. 1472 01:11:24,720 --> 01:11:26,210 But then that would require Jeffrey 1473 01:11:26,210 --> 01:11:28,410 to scan through the whole page. 1474 01:11:28,410 --> 01:11:32,060 And then so we finalized on this sketch. 1475 01:11:32,060 --> 01:11:34,330 So there are two siting rulers. 1476 01:11:34,330 --> 01:11:37,230 Ideally, each ruler will have like brailles on it 1477 01:11:37,230 --> 01:11:40,520 so that he can know how far he's gone on the page. 1478 01:11:40,520 --> 01:11:44,150 So both rulers kind of slide left and right and also 1479 01:11:44,150 --> 01:11:45,220 the other's up and down. 1480 01:11:47,860 --> 01:11:50,230 Yeah and then just the idea-- you don't you read it. 1481 01:11:50,230 --> 01:11:53,810 But it's just how much Jeffrey's input is given to us, 1482 01:11:53,810 --> 01:11:56,290 and also he's really passionate about this project. 1483 01:11:59,130 --> 01:12:02,360 DAVID KE: So this is the general timeline for what we're doing. 1484 01:12:02,360 --> 01:12:03,860 So in the next few weeks, it's going 1485 01:12:03,860 --> 01:12:06,661 to be focused on mostly making more prototypes 1486 01:12:06,661 --> 01:12:08,160 for these projects, and we're really 1487 01:12:08,160 --> 01:12:10,800 ramping up our interactions with Jeffrey 1488 01:12:10,800 --> 01:12:13,604 to get feedback and iterate on our designs. 1489 01:12:13,604 --> 01:12:15,520 So like as you've seen in the previous slides, 1490 01:12:15,520 --> 01:12:17,322 we already have a really lo-fi prototype. 1491 01:12:17,322 --> 01:12:19,280 So what we're going to do in the next two weeks 1492 01:12:19,280 --> 01:12:22,890 is prepare multiple versions with minor detail differences 1493 01:12:22,890 --> 01:12:25,210 to Jeffrey to see which ones he likes. 1494 01:12:25,210 --> 01:12:27,460 Because a lot of it, the general idea is pretty solid, 1495 01:12:27,460 --> 01:12:29,001 but a lot of it's like in the details 1496 01:12:29,001 --> 01:12:30,960 of how unexpected things might come up 1497 01:12:30,960 --> 01:12:32,930 as he uses it day to day. 1498 01:12:32,930 --> 01:12:36,390 And in a few weeks, once we kind of have that hammered out, 1499 01:12:36,390 --> 01:12:38,540 we'll try to work on like a more high fidelity 1500 01:12:38,540 --> 01:12:40,351 prototype that this more closer to what 1501 01:12:40,351 --> 01:12:42,850 we'll be presenting at the end in the beginning of November. 1502 01:12:45,890 --> 01:12:50,346 And on the software side, this is more like on our side 1503 01:12:50,346 --> 01:12:51,970 because we need to kind of get familiar 1504 01:12:51,970 --> 01:12:54,630 with hows JAWS is working, as well as like what kind 1505 01:12:54,630 --> 01:12:58,810 of inputs to outputs we can give to JAWS as well as from JAWS. 1506 01:12:58,810 --> 01:13:02,186 And then we're aiming to sort of complete that little bit 1507 01:13:02,186 --> 01:13:03,560 after hardware, so we can kind of 1508 01:13:03,560 --> 01:13:06,143 combine it together and have a few weeks to see how that would 1509 01:13:06,143 --> 01:13:07,740 work as a complete package. 1510 01:13:10,960 --> 01:13:17,191 And this is just what we've done so far-- yay, teamwork. 1511 01:13:17,191 --> 01:13:18,441 OK, and that's the last slide. 1512 01:13:27,390 --> 01:13:30,380 YI TONG: Well, he obviously had a lot of ideas, 1513 01:13:30,380 --> 01:13:34,560 and I'm wondering how you chose, or what 1514 01:13:34,560 --> 01:13:37,820 process you used to choose this signature project? 1515 01:13:37,820 --> 01:13:41,710 Was it sort of an embodiment of your skills and interests, 1516 01:13:41,710 --> 01:13:45,170 or was it like clear front runner for him? 1517 01:13:45,170 --> 01:13:47,580 DAVID KE: So I think two main categories 1518 01:13:47,580 --> 01:13:49,250 we were considering in that was, one, 1519 01:13:49,250 --> 01:13:52,280 is it something that aligned with our skills, 1520 01:13:52,280 --> 01:13:56,190 because we're all studying computer science. 1521 01:13:56,190 --> 01:13:57,940 He also had a bunch of projects that 1522 01:13:57,940 --> 01:13:59,980 were pretty cool that wasn't that involved, 1523 01:13:59,980 --> 01:14:01,960 like mostly mechanical engineering. 1524 01:14:01,960 --> 01:14:04,530 So that was like a little out of the reach of our abilities. 1525 01:14:04,530 --> 01:14:06,696 At the same time, something else we have to consider 1526 01:14:06,696 --> 01:14:10,900 was we needed a project that was the right scope for the class. 1527 01:14:10,900 --> 01:14:13,140 So like, for example, the Excel thing he mentioned, 1528 01:14:13,140 --> 01:14:16,240 it's mostly computers, but it was very simple. 1529 01:14:16,240 --> 01:14:19,231 So we wanted something that had more substance to it that 1530 01:14:19,231 --> 01:14:21,022 could be applied to more people afterwards. 1531 01:14:25,974 --> 01:14:28,390 PROFESSOR 1: I have a question about your baseline success 1532 01:14:28,390 --> 01:14:32,980 metrics because you did say that signing documents is something 1533 01:14:32,980 --> 01:14:35,860 does do with Neil's help. 1534 01:14:35,860 --> 01:14:38,610 Have you watched him to do that with Niel's help? 1535 01:14:38,610 --> 01:14:41,100 Have you sort of collected examples of his signature 1536 01:14:41,100 --> 01:14:43,080 that he's done with Neils help? 1537 01:14:43,080 --> 01:14:46,474 Seems like that you're not just operating with something 1538 01:14:46,474 --> 01:14:47,890 that he's completely unable to do, 1539 01:14:47,890 --> 01:14:50,960 but something he just can't do independently yet. 1540 01:14:50,960 --> 01:14:53,460 JODIE CHEN: Well, he wants to be able to do it independently 1541 01:14:53,460 --> 01:14:55,220 because Neil isn't always there. 1542 01:14:55,220 --> 01:14:58,679 And we haven't really had a chance to watch Neil show him 1543 01:14:58,679 --> 01:15:03,850 where the signature line is and how to sign it because, so far, 1544 01:15:03,850 --> 01:15:07,081 we've only gone to his house once because he comes 1545 01:15:07,081 --> 01:15:08,580 to Monday, Wednesday class sections, 1546 01:15:08,580 --> 01:15:10,080 but also lab sections, so we've been 1547 01:15:10,080 --> 01:15:13,090 meeting with him for around four hours 1548 01:15:13,090 --> 01:15:14,972 every week during class time. 1549 01:15:14,972 --> 01:15:16,930 DAVID KE: Yeah, but I think that's a good idea, 1550 01:15:16,930 --> 01:15:18,688 and it's something we should definitely do 1551 01:15:18,688 --> 01:15:20,630 the next time we meet with him. 1552 01:15:20,630 --> 01:15:24,500 I suspect we'll have to consider that 1553 01:15:24,500 --> 01:15:26,770 as like two different categories of like metrics, 1554 01:15:26,770 --> 01:15:30,730 but it's something that should be included 1555 01:15:30,730 --> 01:15:33,811 PROFESSOR 2: So I'm curious more about the mechanical aspect 1556 01:15:33,811 --> 01:15:34,310 then. 1557 01:15:34,310 --> 01:15:37,160 So you guys are really comfortable with the software 1558 01:15:37,160 --> 01:15:39,634 side, and you presented the first prototype 1559 01:15:39,634 --> 01:15:41,050 of the mechanical side, and you've 1560 01:15:41,050 --> 01:15:44,990 showed kind of your sketch of how the camera might be there 1561 01:15:44,990 --> 01:15:46,280 and where the rulers might be. 1562 01:15:46,280 --> 01:15:48,113 But you talked about some of the limitations 1563 01:15:48,113 --> 01:15:51,064 potentially for just being able to kind of look 1564 01:15:51,064 --> 01:15:53,230 at where you put your head, where you put your hand. 1565 01:15:53,230 --> 01:15:54,890 I want you to talk a little bit more 1566 01:15:54,890 --> 01:15:56,950 about some of those limitations and things 1567 01:15:56,950 --> 01:16:00,600 you're thinking about from the mechanical side, 1568 01:16:00,600 --> 01:16:05,750 and what you think you might do to balance that. 1569 01:16:05,750 --> 01:16:09,150 YI TONG: I think I might have misrepresented because I feel 1570 01:16:09,150 --> 01:16:12,091 like the camera thing is just like the earlier prototypes 1571 01:16:12,091 --> 01:16:14,590 that we explored, but we're not going to do the camera side. 1572 01:16:14,590 --> 01:16:16,490 We're just going to keep the software part, 1573 01:16:16,490 --> 01:16:17,840 the mechi part separate. 1574 01:16:17,840 --> 01:16:20,036 So the mechi part is independent. 1575 01:16:20,036 --> 01:16:21,410 It only takes in the coordinates. 1576 01:16:21,410 --> 01:16:23,620 And then Jeffrey will get feedback 1577 01:16:23,620 --> 01:16:26,390 when he's sliding the rulers, so he knows how far he's gone, 1578 01:16:26,390 --> 01:16:29,240 but he doesn't have to have a camera take down 1579 01:16:29,240 --> 01:16:31,320 where his hand is currently on. 1580 01:16:31,320 --> 01:16:33,250 DAVID KE: Yeah, and one good thing about this 1581 01:16:33,250 --> 01:16:36,090 is I think Jeffrey and us are pretty 1582 01:16:36,090 --> 01:16:38,980 aligned in that we want to keep the amount 1583 01:16:38,980 --> 01:16:42,540 of complicated components in the final project like minimized 1584 01:16:42,540 --> 01:16:44,849 to reduce possibility of failure. 1585 01:16:44,849 --> 01:16:46,390 So a lot of the things we've actually 1586 01:16:46,390 --> 01:16:47,950 talked about in the past few weeks 1587 01:16:47,950 --> 01:16:50,392 are ways to simplify the parts so that it still 1588 01:16:50,392 --> 01:16:52,600 has the relevant information, but it's like as simple 1589 01:16:52,600 --> 01:16:53,100 as possible. 1590 01:16:56,015 --> 01:16:57,640 PROFESSOR 4: Any questions or comments? 1591 01:16:57,640 --> 01:17:00,614 AUDIENCE: You mentioned using a mouse [INAUDIBLE]. 1592 01:17:00,614 --> 01:17:03,030 But wouldn't that require him to click all over the screen 1593 01:17:03,030 --> 01:17:05,356 to find out where the signature line is, or are you 1594 01:17:05,356 --> 01:17:06,950 just going to have he reads through it with JAWS 1595 01:17:06,950 --> 01:17:08,408 and then stops when he finds lines. 1596 01:17:10,622 --> 01:17:12,830 JODIE CHEN: So it's more likely to be like the latter 1597 01:17:12,830 --> 01:17:15,400 because he's done that. 1598 01:17:15,400 --> 01:17:17,997 For JAWS, when JAWS is reading something on the screen, 1599 01:17:17,997 --> 01:17:21,476 it has a [INAUDIBLE] somewhat similar [? to mouse clicks, ?] 1600 01:17:21,476 --> 01:17:23,970 but they're not actually mouse [INAUDIBLE]. 1601 01:17:23,970 --> 01:17:25,636 And then there's like a function in JAWS 1602 01:17:25,636 --> 01:17:29,981 where it moves the mouse pointer to the location of where 1603 01:17:29,981 --> 01:17:31,255 it's currently reading. 1604 01:17:31,255 --> 01:17:32,963 So that's how we're planning on doing it. 1605 01:17:36,939 --> 01:17:38,707 PROFESSOR 4: Any questions, comments? 1606 01:17:38,707 --> 01:17:40,915 So quick clarification, so is there like a scanning-- 1607 01:17:40,915 --> 01:17:41,412 maybe I missed it. 1608 01:17:41,412 --> 01:17:43,400 Is there some scanning of the document first? 1609 01:17:43,400 --> 01:17:45,388 Are you buying a scanner? 1610 01:17:45,388 --> 01:17:47,429 JODIE CHEN: Oh, he always scans in his documents. 1611 01:17:53,340 --> 01:17:56,224 AUDIENCE: I was hoping to [INAUDIBLE] Jeffrey briefly. 1612 01:17:56,224 --> 01:17:58,807 Is it going to be an issue when the line is like a drawn line, 1613 01:17:58,807 --> 01:18:01,292 as opposed to [INAUDIBLE] line? 1614 01:18:01,292 --> 01:18:03,280 Or will that resolve with the scanner? 1615 01:18:06,107 --> 01:18:08,690 DAVID KE: That just depends on like the of quality of the line 1616 01:18:08,690 --> 01:18:13,179 as well as like the character recognition software. 1617 01:18:13,179 --> 01:18:14,678 So we'll probably do tests with that 1618 01:18:14,678 --> 01:18:16,678 to see like how much tolerance the software has. 1619 01:18:19,125 --> 01:18:20,666 PROFESSOR 4: Michelle, last question. 1620 01:18:20,666 --> 01:18:22,207 AUDIENCE: Is there a general location 1621 01:18:22,207 --> 01:18:24,159 where you know the lines are going to be. 1622 01:18:24,159 --> 01:18:26,277 Just out of curiosity, like if I sign a paper, 1623 01:18:26,277 --> 01:18:28,151 it's usually at the bottom right-hand corner. 1624 01:18:28,151 --> 01:18:29,149 Do you guys have an understanding 1625 01:18:29,149 --> 01:18:31,190 of what kind of documents he's currently signing, 1626 01:18:31,190 --> 01:18:32,749 like what they look like? 1627 01:18:32,749 --> 01:18:35,040 YI TONG: According to Jeffrey, I think it varies a lot. 1628 01:18:35,040 --> 01:18:37,860 And also sometimes like there's a huge line, 1629 01:18:37,860 --> 01:18:41,580 but then the signature word is under the line, 1630 01:18:41,580 --> 01:18:44,330 but sometimes it's just next to it. 1631 01:18:44,330 --> 01:18:46,060 And then sometimes, the signature's 1632 01:18:46,060 --> 01:18:48,252 right here on the left of page, but then you 1633 01:18:48,252 --> 01:18:49,960 have to sign it to the right of the page. 1634 01:18:49,960 --> 01:18:53,670 So it really depends on different kinds of paperwork. 1635 01:18:53,670 --> 01:18:57,320 So we tried to collect all different kinds of paperwork 1636 01:18:57,320 --> 01:18:59,080 that he normally gets, and then we 1637 01:18:59,080 --> 01:19:03,080 tried to characterize like what different kinds of signature 1638 01:19:03,080 --> 01:19:06,317 box that he normally gets and then work on that. 1639 01:19:06,317 --> 01:19:07,900 JODIE CHEN: And also what Jeffrey does 1640 01:19:07,900 --> 01:19:11,100 is he scans a document, and then he runs OCR on it, 1641 01:19:11,100 --> 01:19:15,400 and then he translates it into a Word document, 1642 01:19:15,400 --> 01:19:17,620 and then he prints out the Word document to sign. 1643 01:19:17,620 --> 01:19:21,020 So what's going to happen is that he alters the document 1644 01:19:21,020 --> 01:19:23,200 that he gets in mail pretty significantly when 1645 01:19:23,200 --> 01:19:26,692 he runs OCR and changes it to a Word document. 1646 01:19:26,692 --> 01:19:29,150 DAVID KE: But overall he gets a lot of different signatures 1647 01:19:29,150 --> 01:19:31,855 on that. 1648 01:19:31,855 --> 01:19:34,480 PROFESSOR 2: It would be really interesting to actually try out 1649 01:19:34,480 --> 01:19:37,190 that and get those documents for all these different signature 1650 01:19:37,190 --> 01:19:37,530 lines. 1651 01:19:37,530 --> 01:19:39,113 And I think that's a really good point 1652 01:19:39,113 --> 01:19:42,100 about whether it's an underscore line or a drawn line, 1653 01:19:42,100 --> 01:19:45,196 and some signatures are actually boxes as opposed to lines 1654 01:19:45,196 --> 01:19:46,404 and how that might affect it. 1655 01:19:50,850 --> 01:19:52,021 PROFESSOR 4: OK, thank you. 1656 01:20:01,812 --> 01:20:03,770 VYNNIE KONG: Everyone, we are Team Beverly Ann. 1657 01:20:03,770 --> 01:20:05,482 This is our mid-semester review. 1658 01:20:05,482 --> 01:20:06,190 My name's Vynnie. 1659 01:20:06,190 --> 01:20:07,420 SHRUTHI NARAYANAN: I'm Shruthi. 1660 01:20:07,420 --> 01:20:08,420 ROBERT LUO : I'm Robert. 1661 01:20:12,310 --> 01:20:13,810 VYNNIE KONG: And we're just going 1662 01:20:13,810 --> 01:20:17,160 to provide you a brief introduction to our client. 1663 01:20:17,160 --> 01:20:19,350 So some of the non technical things-- Beverly-Ann 1664 01:20:19,350 --> 01:20:22,400 is a social worker for DCF, so that's 1665 01:20:22,400 --> 01:20:24,740 the Division of Children with Families, 1666 01:20:24,740 --> 01:20:27,290 so she basically works at a sort of law firm. 1667 01:20:27,290 --> 01:20:29,165 And she's actually learning how to code using 1668 01:20:29,165 --> 01:20:32,180 and Scratch Arduino, which we thought were pretty cool. 1669 01:20:32,180 --> 01:20:33,710 She loves playing Wi tennis. 1670 01:20:33,710 --> 01:20:36,000 She has a backyard garden, so she 1671 01:20:36,000 --> 01:20:37,820 grows tomatoes and marigolds. 1672 01:20:37,820 --> 01:20:41,110 And most importantly, she wants to maintain an active mind 1673 01:20:41,110 --> 01:20:43,790 in order to keep busy and kind of like 1674 01:20:43,790 --> 01:20:46,730 find something useful for the rest of her life. 1675 01:20:46,730 --> 01:20:49,630 And before we explain more about stuff 1676 01:20:49,630 --> 01:20:51,390 related to the HAAT model, we think 1677 01:20:51,390 --> 01:20:53,850 the video would be a very good descriptor 1678 01:20:53,850 --> 01:20:55,598 of a lot of these things. 1679 01:20:55,598 --> 01:20:59,990 [VIDEO PLAYBACK] 1680 01:20:59,990 --> 01:21:02,870 -Hello, my name is Beverly Ann Rock, 1681 01:21:02,870 --> 01:21:06,144 and I have been diagnosed with CMT, which 1682 01:21:06,144 --> 01:21:07,435 stands for Charcot-Marie-Tooth. 1683 01:21:20,660 --> 01:21:24,300 I was diagnosed about 11 years ago. 1684 01:21:24,300 --> 01:21:26,440 If there's any blessings to this disease 1685 01:21:26,440 --> 01:21:28,550 or anything good about this disease, is 1686 01:21:28,550 --> 01:21:31,200 it only affects the hands and the legs, 1687 01:21:31,200 --> 01:21:35,770 which means I'll always have my ability to talk. 1688 01:21:35,770 --> 01:21:39,800 Three of my 10 fingers have taken on the deformity, which 1689 01:21:39,800 --> 01:21:41,360 means they're kind of locked. 1690 01:21:41,360 --> 01:21:45,220 And eventually, they will end up in gnarled positions. 1691 01:21:45,220 --> 01:21:49,900 But fortunately, 7 is better than none. 1692 01:21:49,900 --> 01:21:53,660 So I use my seven fingers very effectively. 1693 01:21:53,660 --> 01:21:59,970 My right hand, it has become numb in many places. 1694 01:21:59,970 --> 01:22:02,510 Thus it doesn't give me the opportunity 1695 01:22:02,510 --> 01:22:06,610 to use very simple devices. 1696 01:22:06,610 --> 01:22:10,290 So if I were to be trying to drink something hot, 1697 01:22:10,290 --> 01:22:13,590 I would make sure to try to grip it as best I can 1698 01:22:13,590 --> 01:22:15,760 and support it. 1699 01:22:15,760 --> 01:22:18,932 But over time, it's not going to hold. 1700 01:22:18,932 --> 01:22:20,890 It's going to slip, I'm going to lose the grip. 1701 01:22:26,580 --> 01:22:29,610 That's one of my concerns is dropping stuff 1702 01:22:29,610 --> 01:22:32,990 and why I'm so guarded about dropping 1703 01:22:32,990 --> 01:22:39,240 is if you drop a glass, a shard, I had a couple times, 1704 01:22:39,240 --> 01:22:41,490 a little thing has just stuck into my foot, 1705 01:22:41,490 --> 01:22:45,230 and I didn't realize it till I looked down and said, 1706 01:22:45,230 --> 01:22:46,810 why am I bleeding? 1707 01:22:46,810 --> 01:22:54,450 I Constantly fall, and I always have devices or walkers 1708 01:22:54,450 --> 01:22:57,060 or scooters or things that will enable 1709 01:22:57,060 --> 01:23:00,268 me to maintain balance and continue to be mobile. 1710 01:23:03,730 --> 01:23:06,620 I choose, at this point in my life, to work, 1711 01:23:06,620 --> 01:23:08,671 even though I'm at retirement age, 1712 01:23:08,671 --> 01:23:10,836 and that's because it keeps my mind busy. 1713 01:23:13,730 --> 01:23:18,220 And hopefully every day they're working on a cure, 1714 01:23:18,220 --> 01:23:20,870 or I stumble on a program like you 1715 01:23:20,870 --> 01:23:26,060 that is going to assist me to make things a little easier. 1716 01:23:26,060 --> 01:23:29,020 So if I had a device that was telling me, 1717 01:23:29,020 --> 01:23:30,860 if I got too into the conversation, 1718 01:23:30,860 --> 01:23:33,466 that it's loosening, then I when know to go back and not 1719 01:23:33,466 --> 01:23:40,394 use the assistance to go back and try to tighten the grip. 1720 01:23:40,394 --> 01:23:41,810 -We have to distract you some how. 1721 01:23:41,810 --> 01:23:43,935 -You are distracting me because why you're talking, 1722 01:23:43,935 --> 01:23:45,600 I'm saying, OK, hold on. 1723 01:23:53,879 --> 01:23:57,790 [END PLAYBACK] 1724 01:23:57,790 --> 01:24:02,220 SHRUTHI NARAYANAN: So, as she said in the video, she has CMT. 1725 01:24:02,220 --> 01:24:03,770 It's a neurodegenerative disease that 1726 01:24:03,770 --> 01:24:07,660 affects the extremities, so the hands and the feet. 1727 01:24:07,660 --> 01:24:10,970 It results in a loss of touch sensation and muscle control. 1728 01:24:10,970 --> 01:24:13,170 So she has involuntary muscle spasms. 1729 01:24:13,170 --> 01:24:15,685 For her, in particular, we're interested in her hands. 1730 01:24:15,685 --> 01:24:18,310 So it means that she has sensory failures in part of your hands 1731 01:24:18,310 --> 01:24:21,030 and muscle failure in others. 1732 01:24:21,030 --> 01:24:23,890 And this is like a general diagram 1733 01:24:23,890 --> 01:24:25,880 of her left and right hand. 1734 01:24:25,880 --> 01:24:29,430 On her left hand, you can see the green fingers are curled in 1735 01:24:29,430 --> 01:24:30,450 like this. 1736 01:24:30,450 --> 01:24:32,820 And that's because that's their natural position. 1737 01:24:32,820 --> 01:24:34,903 So when she tries to open them, they automatically 1738 01:24:34,903 --> 01:24:35,580 curl back in. 1739 01:24:35,580 --> 01:24:38,160 So this is like the involuntary muscle movement. 1740 01:24:38,160 --> 01:24:40,960 But her other two fingers are very mobile. 1741 01:24:40,960 --> 01:24:42,980 So even though she can't grip anything just 1742 01:24:42,980 --> 01:24:44,840 with the left hand, she uses her left hand 1743 01:24:44,840 --> 01:24:46,880 to support what she's gripping a lot. 1744 01:24:46,880 --> 01:24:49,364 On her right hand, the red regions, 1745 01:24:49,364 --> 01:24:50,780 which are most of her fingers, are 1746 01:24:50,780 --> 01:24:52,760 the places where her hands are numb, 1747 01:24:52,760 --> 01:24:55,020 so she can't feel anything. 1748 01:24:55,020 --> 01:24:56,760 And so she has a hard time gripping 1749 01:24:56,760 --> 01:24:58,250 with those parts of her fingers. 1750 01:24:58,250 --> 01:25:01,740 But the tips of her fingertips, which are marked in blue, 1751 01:25:01,740 --> 01:25:03,310 are actually fully sensitive. 1752 01:25:03,310 --> 01:25:06,680 So she tends to claw whenever she's picking things up. 1753 01:25:06,680 --> 01:25:10,650 But over time, she still loses grip with her right hand. 1754 01:25:13,195 --> 01:25:14,820 VYNNIE KONG: Because of the combination 1755 01:25:14,820 --> 01:25:19,560 of loss of pressure and also involuntary muscle movements, 1756 01:25:19,560 --> 01:25:22,500 there are certain activities that Beverly Ann has trouble 1757 01:25:22,500 --> 01:25:23,800 with on a day-to-day basis. 1758 01:25:23,800 --> 01:25:26,630 And then I made a table with modifications 1759 01:25:26,630 --> 01:25:28,650 that she's learned to do to adapt. 1760 01:25:28,650 --> 01:25:31,306 So a lot of the things she has trouble with 1761 01:25:31,306 --> 01:25:34,167 is having to consciously think about doing 1762 01:25:34,167 --> 01:25:35,000 everything she does. 1763 01:25:35,000 --> 01:25:38,250 So any time she has to pick up something to drink of water, 1764 01:25:38,250 --> 01:25:39,730 any time she has to type something, 1765 01:25:39,730 --> 01:25:42,440 she needs to think about every single letter she types, 1766 01:25:42,440 --> 01:25:45,650 rather than just typing out of muscle memory. 1767 01:25:45,650 --> 01:25:48,321 And that's difficult, especially when 1768 01:25:48,321 --> 01:25:50,070 you're holding a conversation with someone 1769 01:25:50,070 --> 01:25:52,630 or if you're just thinking about something else. 1770 01:25:52,630 --> 01:25:55,460 You can't always think about what you're doing all the time. 1771 01:25:55,460 --> 01:25:58,080 This also helps with walking down stairwells, 1772 01:25:58,080 --> 01:26:00,880 because she has to grip onto the stairwell 1773 01:26:00,880 --> 01:26:04,050 and make sure she squeezes every couple of seconds, 1774 01:26:04,050 --> 01:26:07,570 so if she's managed to stumble, she'll still have the grip 1775 01:26:07,570 --> 01:26:09,202 and be able to stabilize herself. 1776 01:26:09,202 --> 01:26:11,660 And the last thing is actually cooking, which he brought up 1777 01:26:11,660 --> 01:26:15,410 in a meeting, where she realized when she was cooking potatoes 1778 01:26:15,410 --> 01:26:18,140 and she was picking up potatoes to put them in the pot 1779 01:26:18,140 --> 01:26:20,627 that she wasn't actually grabbing on to them. 1780 01:26:20,627 --> 01:26:22,710 So she had to use this sort of like clawing motion 1781 01:26:22,710 --> 01:26:25,750 to get them from the cutting board into the pot. 1782 01:26:29,225 --> 01:26:31,600 ROBERT LUO : So the basic problem we're dealing with here 1783 01:26:31,600 --> 01:26:35,360 is that she has to constantly think about the things 1784 01:26:35,360 --> 01:26:38,590 she's grabbing whenever she's grabbing some kind of object. 1785 01:26:38,590 --> 01:26:42,800 And also, she is not really confident in using 1786 01:26:42,800 --> 01:26:46,190 just her right hand for grabbing objects. 1787 01:26:46,190 --> 01:26:50,360 Instead she normally uses her left hand to do the support. 1788 01:26:50,360 --> 01:26:54,720 And we want to come up with the device which would help her 1789 01:26:54,720 --> 01:26:59,420 by notifying her when she first-- helping her to have 1790 01:26:59,420 --> 01:27:03,010 the confidence to grab objects with just her right hand, 1791 01:27:03,010 --> 01:27:08,960 and then notifying her whenever her gripping starts to become 1792 01:27:08,960 --> 01:27:11,110 loose. 1793 01:27:11,110 --> 01:27:14,390 So then we came up with the success metrics 1794 01:27:14,390 --> 01:27:15,300 for our project. 1795 01:27:15,300 --> 01:27:17,930 There are few things we can think about. 1796 01:27:17,930 --> 01:27:25,230 So the first thing is we want to see how much of a percentage 1797 01:27:25,230 --> 01:27:27,630 our device could give her the warning. 1798 01:27:27,630 --> 01:27:29,750 So right now, of course, it's zero. 1799 01:27:29,750 --> 01:27:32,930 But we think a reasonable goal will 50%. 1800 01:27:32,930 --> 01:27:35,600 Meaning that our device will be able to alert 1801 01:27:35,600 --> 01:27:39,730 her 50% of the time whenever her grip starts to become loose, 1802 01:27:39,730 --> 01:27:42,490 and then with an ambitious goal of 90%. 1803 01:27:42,490 --> 01:27:44,520 And then the second success metric 1804 01:27:44,520 --> 01:27:47,890 is the dropping rate with just her right hand. 1805 01:27:47,890 --> 01:27:51,850 And so this part we still need to measure how many times, 1806 01:27:51,850 --> 01:27:54,510 how many things she drops on average in a day, 1807 01:27:54,510 --> 01:27:56,270 and then we want to decrease that 1808 01:27:56,270 --> 01:28:03,400 by 50% as our reasonable goal, and 20% off the original 1809 01:28:03,400 --> 01:28:05,340 as our ambitious goal. 1810 01:28:05,340 --> 01:28:08,850 And then we want to boost her confidence in gripping objects 1811 01:28:08,850 --> 01:28:10,800 with just her right hand. 1812 01:28:10,800 --> 01:28:15,510 And we can measure how many times 1813 01:28:15,510 --> 01:28:19,100 she grabs things in a weekly basis or a daily basis. 1814 01:28:19,100 --> 01:28:23,280 And then we want to increase the percentage of her just 1815 01:28:23,280 --> 01:28:27,530 using her the right hand to grab to 60%, then eventually 90%. 1816 01:28:31,160 --> 01:28:36,380 And so this is our design process for this device. 1817 01:28:36,380 --> 01:28:38,410 So first, we define the goals. 1818 01:28:38,410 --> 01:28:41,200 So we noticed that she has two different problems 1819 01:28:41,200 --> 01:28:42,970 for her left hand and her right hand. 1820 01:28:42,970 --> 01:28:45,380 And after talking with our mentor Jeff, 1821 01:28:45,380 --> 01:28:47,560 we decided to focus on solving her problem 1822 01:28:47,560 --> 01:28:50,740 with the right hand, so meaning the gripping part. 1823 01:28:50,740 --> 01:28:53,270 Then we brainstormed of different ideas. 1824 01:28:53,270 --> 01:28:55,690 We mainly focused on whether we should use a sensor, 1825 01:28:55,690 --> 01:28:58,440 and if yes, where should we put the sensor 1826 01:28:58,440 --> 01:29:03,510 as well as how we can attach the sensor to her hand? 1827 01:29:03,510 --> 01:29:07,580 Then we come with various types of prototypes, 1828 01:29:07,580 --> 01:29:10,320 many based on the location of the sensor 1829 01:29:10,320 --> 01:29:14,620 as well as the style of attachment of the sensor. 1830 01:29:14,620 --> 01:29:17,390 So the fundamental idea of our design 1831 01:29:17,390 --> 01:29:21,870 is to have a way to quantify the pressures she exercises when 1832 01:29:21,870 --> 01:29:24,110 she grabs things as well as trying 1833 01:29:24,110 --> 01:29:27,860 to have a way to notify her when her grip becomes loose. 1834 01:29:30,394 --> 01:29:32,310 SHRUTHI NARAYANAN: So the first concept we had 1835 01:29:32,310 --> 01:29:34,730 was to place the sensors near the palm of her right hand, 1836 01:29:34,730 --> 01:29:36,110 so that would be in this area. 1837 01:29:36,110 --> 01:29:38,000 We figured that we wanted as little material 1838 01:29:38,000 --> 01:29:40,580 on her hand as possible, so it wouldn't weigh her down and so 1839 01:29:40,580 --> 01:29:42,800 that it wouldn't look like a very obvious device. 1840 01:29:42,800 --> 01:29:44,180 And then on the back of the hand, 1841 01:29:44,180 --> 01:29:45,388 you can see there's a square. 1842 01:29:45,388 --> 01:29:47,280 That would be where the sensors read out to. 1843 01:29:47,280 --> 01:29:48,480 There would be some sort of output 1844 01:29:48,480 --> 01:29:50,640 there that she could look or that would notify her 1845 01:29:50,640 --> 01:29:51,950 when her grip is slipping. 1846 01:29:51,950 --> 01:29:54,694 So this was good because it was very small and condensed, 1847 01:29:54,694 --> 01:29:56,360 and she'd still have use of her fingers. 1848 01:29:56,360 --> 01:29:58,760 But it was bad because she tends to grip with her fingertips. 1849 01:29:58,760 --> 01:30:01,210 So we wouldn't actually be able to sense a lot of the grip 1850 01:30:01,210 --> 01:30:02,480 that she was using. 1851 01:30:02,480 --> 01:30:06,007 And so we would basically get no reading most of the time 1852 01:30:06,007 --> 01:30:07,840 So then we came up with an exciting concept, 1853 01:30:07,840 --> 01:30:10,280 which was to place the sensors on the tips of the fingers. 1854 01:30:10,280 --> 01:30:12,530 If you can see, everything except for the index finger 1855 01:30:12,530 --> 01:30:13,646 has a sensor. 1856 01:30:13,646 --> 01:30:16,020 That's because she actually doesn't use your index finger 1857 01:30:16,020 --> 01:30:17,050 very much when gripping. 1858 01:30:17,050 --> 01:30:19,429 So the other four fingers have sensors. 1859 01:30:19,429 --> 01:30:20,970 They wrap around the back of the hand 1860 01:30:20,970 --> 01:30:23,301 to go to the same output box. 1861 01:30:23,301 --> 01:30:25,800 This is much better because she grips with their fingertips, 1862 01:30:25,800 --> 01:30:27,758 so we can actually sense what's she's gripping. 1863 01:30:27,758 --> 01:30:30,790 But it does take up more of her hand. 1864 01:30:30,790 --> 01:30:32,590 In the end, we went with a second concept, 1865 01:30:32,590 --> 01:30:35,455 and this is because we asked her about how she felt about having 1866 01:30:35,455 --> 01:30:36,330 a device on her hand. 1867 01:30:36,330 --> 01:30:38,462 And she was like, I don't care what it looks like. 1868 01:30:38,462 --> 01:30:40,920 It could be pretty big, and I would be OK with that as long 1869 01:30:40,920 --> 01:30:42,460 as it helps me to grip. 1870 01:30:42,460 --> 01:30:46,492 So we made some very basic prototypes of just the shape 1871 01:30:46,492 --> 01:30:47,700 of what they would look like. 1872 01:30:47,700 --> 01:30:51,610 So the sensors are the sort of strips of paper, 1873 01:30:51,610 --> 01:30:53,380 and we just wanted to see how they 1874 01:30:53,380 --> 01:30:58,775 would look so that we can sort of experiment with how 1875 01:30:58,775 --> 01:30:59,650 they fit on her hand. 1876 01:30:59,650 --> 01:31:01,105 So if you want to-- 1877 01:31:04,020 --> 01:31:06,340 VYNNIE KONG: So a bit of a future timeline, 1878 01:31:06,340 --> 01:31:10,530 we are planning by next week, so October 29th, to start 1879 01:31:10,530 --> 01:31:12,280 and basically finished figuring out 1880 01:31:12,280 --> 01:31:15,100 the circuitry for connecting these sensors to some sort 1881 01:31:15,100 --> 01:31:18,020 of output voltage, and we want to tune the circuit so 1882 01:31:18,020 --> 01:31:20,830 that whatever output voltage the sensors produce 1883 01:31:20,830 --> 01:31:24,385 will be in a format that's interpretable to our needs. 1884 01:31:26,645 --> 01:31:28,520 SHRUTHI NARAYANAN: Then we want to write code 1885 01:31:28,520 --> 01:31:29,978 to respond to the sensor so that we 1886 01:31:29,978 --> 01:31:33,110 can give her a sort of output on when she's losing grip. 1887 01:31:33,110 --> 01:31:36,060 So we want to study what the sensor voltage looks 1888 01:31:36,060 --> 01:31:38,870 like as her grip loosens and try to figure out 1889 01:31:38,870 --> 01:31:40,950 where we can start notifying her, 1890 01:31:40,950 --> 01:31:43,770 when like this certain thing happens that, oh, your grip is 1891 01:31:43,770 --> 01:31:44,380 loosening. 1892 01:31:44,380 --> 01:31:46,790 So we plan to try multiple different algorithms for this, 1893 01:31:46,790 --> 01:31:48,790 and this will hopefully be our second prototype, 1894 01:31:48,790 --> 01:31:52,390 and we'll have it done by the first week of November. 1895 01:31:52,390 --> 01:31:54,870 ROBERT LUO : And then the third step is the actual glove we 1896 01:31:54,870 --> 01:31:57,310 will use to attach the sensor with. 1897 01:31:57,310 --> 01:32:00,230 So some things we want to think about in this stage 1898 01:32:00,230 --> 01:32:03,320 is how we want to keep the sensors safe, which 1899 01:32:03,320 --> 01:32:05,780 means we don't want the sensors to be 1900 01:32:05,780 --> 01:32:08,030 exposed to the outside environment as well 1901 01:32:08,030 --> 01:32:08,850 as her hand. 1902 01:32:08,850 --> 01:32:10,550 So maybe something we're thinking about 1903 01:32:10,550 --> 01:32:13,240 is knitting two layers of the gloves 1904 01:32:13,240 --> 01:32:16,310 together and having the sensors to be in the middle. 1905 01:32:16,310 --> 01:32:19,700 So that could protect the sensor from the outside environment 1906 01:32:19,700 --> 01:32:20,550 as well as her hand. 1907 01:32:20,550 --> 01:32:24,320 And then we also want to think about questions like, 1908 01:32:24,320 --> 01:32:27,280 what happens to the sensors when she curls her hand? 1909 01:32:27,280 --> 01:32:30,170 So the way we think about it is that as long 1910 01:32:30,170 --> 01:32:32,300 as we put the sensor on the back of her hand 1911 01:32:32,300 --> 01:32:35,220 or on the wristband, it depends on which one 1912 01:32:35,220 --> 01:32:36,860 we choose eventually. 1913 01:32:36,860 --> 01:32:40,070 Both designs would able to help stable, even 1914 01:32:40,070 --> 01:32:41,170 when she curls her hand. 1915 01:32:47,030 --> 01:32:49,780 And, of course, after we're having the prototypes, 1916 01:32:49,780 --> 01:32:54,420 we want to keep improving on the device based on our test 1917 01:32:54,420 --> 01:32:55,850 results with Beverly Ann. 1918 01:32:58,350 --> 01:33:00,600 VYNNIE KONG: A little bit about our division of work-- 1919 01:33:00,600 --> 01:33:03,310 so during our client meetings, Shruthi 1920 01:33:03,310 --> 01:33:04,940 he has been primarily doing the video. 1921 01:33:04,940 --> 01:33:07,023 I've been primarily doing the interviews, and then 1922 01:33:07,023 --> 01:33:07,850 Robert, the notes. 1923 01:33:07,850 --> 01:33:10,510 And looking onwards, Shruthi and I 1924 01:33:10,510 --> 01:33:11,970 will be planning on working mostly 1925 01:33:11,970 --> 01:33:14,530 on the circuits, and then Robert on most of the gloves 1926 01:33:14,530 --> 01:33:18,012 and figuring out what materials to use. 1927 01:33:18,012 --> 01:33:19,470 And thank you, guys, for listening. 1928 01:33:19,470 --> 01:33:21,095 If you have any questions, let us know. 1929 01:33:27,496 --> 01:33:30,472 PROFESSOR 4: Questions comments from [INAUDIBLE]? 1930 01:33:30,472 --> 01:33:32,180 PROFESSOR 1: I'm wondering if you thought 1931 01:33:32,180 --> 01:33:34,500 about what you might do passively 1932 01:33:34,500 --> 01:33:38,200 with the material of the glove to make it 1933 01:33:38,200 --> 01:33:40,390 less likely that it would slip? 1934 01:33:40,390 --> 01:33:41,265 You know what I mean? 1935 01:33:41,265 --> 01:33:43,350 You have a very active solution right now 1936 01:33:43,350 --> 01:33:47,382 that depends on sensors and electronics and batteries. 1937 01:33:47,382 --> 01:33:49,090 Are there anymore passive things that you 1938 01:33:49,090 --> 01:33:50,650 might do, either with material or with the design 1939 01:33:50,650 --> 01:33:52,157 of the glove, or have you thought 1940 01:33:52,157 --> 01:33:53,365 about that part of the space? 1941 01:33:57,739 --> 01:33:59,530 SHRUTHI NARAYANAN: So one of the big things 1942 01:33:59,530 --> 01:34:02,540 we thought about was when we get the material for designing 1943 01:34:02,540 --> 01:34:04,230 the glove, to have like sort of grip. 1944 01:34:04,230 --> 01:34:06,800 So certain gloves do come with like rubber 1945 01:34:06,800 --> 01:34:09,036 on the outside of them to have more grip, 1946 01:34:09,036 --> 01:34:10,660 and we thought that something like this 1947 01:34:10,660 --> 01:34:12,350 would also be able to help her generally 1948 01:34:12,350 --> 01:34:14,240 keep her grip on slippery objects, 1949 01:34:14,240 --> 01:34:15,520 especially with the glove on. 1950 01:34:15,520 --> 01:34:18,190 So that's one example of a passive solution. 1951 01:34:18,190 --> 01:34:21,540 We did think of entirely passive solutions at the beginning, 1952 01:34:21,540 --> 01:34:23,249 like having some sort of exoskeleton that 1953 01:34:23,249 --> 01:34:25,290 would like hold her group in place that she could 1954 01:34:25,290 --> 01:34:26,750 lock into place or something. 1955 01:34:26,750 --> 01:34:30,890 But we figured that then she'd be having to manipulate 1956 01:34:30,890 --> 01:34:32,430 the device too much herself. 1957 01:34:32,430 --> 01:34:34,780 And so we went with the more active solution in general. 1958 01:34:34,780 --> 01:34:37,240 But yes, smaller passive things, like the rubber grips 1959 01:34:37,240 --> 01:34:40,390 and having some fingers open so that she has better grip, 1960 01:34:40,390 --> 01:34:42,967 will hopefully help her with her grip anyways. 1961 01:34:42,967 --> 01:34:44,550 VYNNIE KONG: And we actually found out 1962 01:34:44,550 --> 01:34:47,740 that a lot of her problems don't come from muscular strength. 1963 01:34:47,740 --> 01:34:50,150 So it's not that she can't physically lift the plate. 1964 01:34:50,150 --> 01:34:53,850 It's just that she can't feel how hard she's gripping it. 1965 01:34:53,850 --> 01:34:56,450 So balancing it becomes a bit of an issue, for example. 1966 01:35:01,715 --> 01:35:03,840 PROFESSOR 5: Well, following on what you just said, 1967 01:35:03,840 --> 01:35:06,506 did you think of any sort of way of giving 1968 01:35:06,506 --> 01:35:08,390 maybe auditory feedback or some way 1969 01:35:08,390 --> 01:35:13,450 to in terms of the gripping, like is there a user interface 1970 01:35:13,450 --> 01:35:14,660 aspect to this? 1971 01:35:14,660 --> 01:35:16,970 ROBERT LUO : Right, so some things we think about is 1972 01:35:16,970 --> 01:35:20,710 so after having a sensors, we want to be able to quantify her 1973 01:35:20,710 --> 01:35:21,210 grip. 1974 01:35:21,210 --> 01:35:24,020 And so some things we are thinking about 1975 01:35:24,020 --> 01:35:28,350 is we can test how much of a grip she exercises on an object 1976 01:35:28,350 --> 01:35:30,550 initially, and then set that as a threshold. 1977 01:35:30,550 --> 01:35:34,110 And whenever the grip comes down to 50% of the original grip, 1978 01:35:34,110 --> 01:35:36,740 then that's the threshold we think of warning her. 1979 01:35:36,740 --> 01:35:38,990 And then and then the ways of warning her 1980 01:35:38,990 --> 01:35:42,080 include having a beeping sound, or it vibrates 1981 01:35:42,080 --> 01:35:44,925 so she will be notified. 1982 01:35:44,925 --> 01:35:47,571 PROFESSOR 5: Did you think about cost? 1983 01:35:47,571 --> 01:35:49,070 Did you say cost, like what it would 1984 01:35:49,070 --> 01:35:52,240 cost to make one of these in quantity or something? 1985 01:35:52,240 --> 01:35:55,950 ROBERT LUO : Oh, right, so we already have the sensors ready. 1986 01:35:55,950 --> 01:35:58,660 So we already got the sensors, so they were not too expensive. 1987 01:35:58,660 --> 01:36:00,750 They were $60, $70. 1988 01:36:00,750 --> 01:36:03,250 And then we know are on the stage of figuring out 1989 01:36:03,250 --> 01:36:05,910 how the circuits would work, and we would approach it 1990 01:36:05,910 --> 01:36:08,840 by making it on a breadboard first, 1991 01:36:08,840 --> 01:36:12,360 then thinking of whether it's possible to make 1992 01:36:12,360 --> 01:36:14,310 this circuits into a smaller circuit board 1993 01:36:14,310 --> 01:36:15,700 and attaching it to the glove. 1994 01:36:15,700 --> 01:36:17,450 And then the glove itself shouldn't really 1995 01:36:17,450 --> 01:36:20,115 be that expensive. 1996 01:36:20,115 --> 01:36:22,240 PROFESSOR 5: Any quick questions from the audience? 1997 01:36:25,356 --> 01:36:27,037 AUDIENCE: [INAUDIBLE]? 1998 01:36:27,037 --> 01:36:28,078 VYNNIE KONG: We have not. 1999 01:36:28,078 --> 01:36:28,620 What is that? 2000 01:36:28,620 --> 01:36:30,661 AUDIENCE: Oh, it's like thread that's in buckets, 2001 01:36:30,661 --> 01:36:32,410 so it's like a wire, but it's thread. 2002 01:36:32,410 --> 01:36:33,243 [INTERPOSING VOICES] 2003 01:36:35,866 --> 01:36:37,740 SHRUTHI NARAYANAN: Yeah, I guess like once we 2004 01:36:37,740 --> 01:36:39,600 have the sensors attached inside the glove 2005 01:36:39,600 --> 01:36:41,885 to get it to the output, we could use that. 2006 01:36:41,885 --> 01:36:43,050 Thank you for the idea. 2007 01:36:50,680 --> 01:36:53,130 STUDENT 1: Hi, we're team Barbara. 2008 01:36:53,130 --> 01:36:54,080 So this is Barbara. 2009 01:36:54,080 --> 01:36:56,430 She has been a teacher for 29 years, 2010 01:36:56,430 --> 01:36:59,910 but she had to retire early because she has PLS. 2011 01:36:59,910 --> 01:37:02,350 So PLS is kind of like ALS. 2012 01:37:02,350 --> 01:37:05,420 It's a disease where your muscles get weaker. 2013 01:37:05,420 --> 01:37:08,700 And right now she is living in the Leonard Florence Center, 2014 01:37:08,700 --> 01:37:10,940 and she really values independence. 2015 01:37:10,940 --> 01:37:15,110 And as of right now, she has fine motor skills in her hands, 2016 01:37:15,110 --> 01:37:18,230 but is slowly losing her strength, especially 2017 01:37:18,230 --> 01:37:20,240 in her left hand because she does 2018 01:37:20,240 --> 01:37:23,840 a lot of crocheting during her free time, which keeps 2019 01:37:23,840 --> 01:37:27,650 her right hand more flexible. 2020 01:37:27,650 --> 01:37:30,510 And she's also constrained to a wheelchair, 2021 01:37:30,510 --> 01:37:33,500 and her speech is sometimes unclear 2022 01:37:33,500 --> 01:37:36,808 because the muscles in her face are also weakening. 2023 01:37:41,210 --> 01:37:44,060 So some of the activities that she has trouble with 2024 01:37:44,060 --> 01:37:46,670 is opening and closing the door in her room. 2025 01:37:46,670 --> 01:37:49,170 This is her door. 2026 01:37:49,170 --> 01:37:53,860 And it's difficult for because the door is very heavy, 2027 01:37:53,860 --> 01:37:57,850 and also it does not swing open. 2028 01:37:57,850 --> 01:38:00,790 When she's trying to open it, it stays where you 2029 01:38:00,790 --> 01:38:03,370 leave it and locks in place. 2030 01:38:03,370 --> 01:38:05,820 Also, because her wheelchair gets in the way 2031 01:38:05,820 --> 01:38:08,050 because the door opens towards her, 2032 01:38:08,050 --> 01:38:09,549 so she has to open it a little bit. 2033 01:38:09,549 --> 01:38:11,340 scoot her chair back, and then open it some 2034 01:38:11,340 --> 01:38:14,280 more, which makes it very difficult. 2035 01:38:14,280 --> 01:38:16,460 Another problem that she has is turning off 2036 01:38:16,460 --> 01:38:19,360 the lights before she goes to sleep because once she's 2037 01:38:19,360 --> 01:38:21,680 in bed, it's very difficult for her to get up 2038 01:38:21,680 --> 01:38:22,680 and turn off the lights. 2039 01:38:24,700 --> 01:38:29,450 Currently, she has an iPhone, and on her iPhone, 2040 01:38:29,450 --> 01:38:31,150 these are some of the apps that she 2041 01:38:31,150 --> 01:38:34,100 uses for assistive technology. 2042 01:38:34,100 --> 01:38:37,100 The ones on the bottom here, some 2043 01:38:37,100 --> 01:38:39,900 are for speaking because her speech is unclear. 2044 01:38:39,900 --> 01:38:42,930 So, for example, there's one for her to say yes or no, 2045 01:38:42,930 --> 01:38:45,440 and some of them where she can type in phrases, 2046 01:38:45,440 --> 01:38:47,530 and it'll speak it for her. 2047 01:38:47,530 --> 01:38:51,590 Or there's also apps for her to indicate the amount of pain 2048 01:38:51,590 --> 01:38:53,020 she has right now. 2049 01:38:53,020 --> 01:38:55,450 She also recently got an iPad, but she 2050 01:38:55,450 --> 01:38:57,870 hasn't been using it that much because it's heavy. 2051 01:38:57,870 --> 01:38:59,890 But she has no assistive technology 2052 01:38:59,890 --> 01:39:02,360 that she uses currently for opening the door 2053 01:39:02,360 --> 01:39:03,480 or turning out the lights. 2054 01:39:06,580 --> 01:39:10,080 So some of the context is that her room is right next 2055 01:39:10,080 --> 01:39:12,390 to the dining area, so sometimes there's 2056 01:39:12,390 --> 01:39:14,560 a lot of noise that bothers her. 2057 01:39:14,560 --> 01:39:16,520 Also, she has concern for privacy 2058 01:39:16,520 --> 01:39:18,580 because since the door is so hard to open, 2059 01:39:18,580 --> 01:39:20,830 she leaves it open most of the time. 2060 01:39:20,830 --> 01:39:23,770 And right now, the staff at the Leonard Florence Center 2061 01:39:23,770 --> 01:39:25,860 has to open and close the door for every day 2062 01:39:25,860 --> 01:39:28,740 and turn on and off the lights. 2063 01:39:28,740 --> 01:39:32,610 And although she didn't ask for a solution for her voice 2064 01:39:32,610 --> 01:39:34,830 problem, she did tell us that this 2065 01:39:34,830 --> 01:39:37,230 is a major concern for her. 2066 01:39:37,230 --> 01:39:40,230 So based on my contextual inquiry, 2067 01:39:40,230 --> 01:39:42,440 we decided on our project, which is 2068 01:39:42,440 --> 01:39:44,802 to automate the door because she really 2069 01:39:44,802 --> 01:39:47,260 wants to have the independence to be able to open and close 2070 01:39:47,260 --> 01:39:50,310 the door by herself, and also have privacy in her room, 2071 01:39:50,310 --> 01:39:53,030 and she doesn't currently have any assistive technology 2072 01:39:53,030 --> 01:39:53,830 for that. 2073 01:39:53,830 --> 01:39:56,230 And that is like the most difficult problem for her right 2074 01:39:56,230 --> 01:39:56,730 now. 2075 01:39:59,260 --> 01:40:03,140 So for success metrics we think the best possible solution 2076 01:40:03,140 --> 01:40:05,270 would be for her to have an app on her phone 2077 01:40:05,270 --> 01:40:08,190 that she would just be able to click or some sensors, 2078 01:40:08,190 --> 01:40:11,920 so she doesn't have to actually opened the door. 2079 01:40:11,920 --> 01:40:14,896 And a less successful solution would be for her 2080 01:40:14,896 --> 01:40:18,440 to press a button and something that would just 2081 01:40:18,440 --> 01:40:20,690 be able to reduce the amount of effort she needs 2082 01:40:20,690 --> 01:40:23,517 is to have her pull something that would then open the door, 2083 01:40:23,517 --> 01:40:25,350 instead of actually opening the door itself. 2084 01:40:27,402 --> 01:40:29,110 STUDENT 2: So next we're going to explain 2085 01:40:29,110 --> 01:40:33,167 a little bit about our ideation process for this door. 2086 01:40:33,167 --> 01:40:34,750 So we're going to start by showing you 2087 01:40:34,750 --> 01:40:39,460 a video of our design process and to give you a bit of sense. 2088 01:40:39,460 --> 01:40:40,380 [VIDEO PLAYBACK] 2089 01:40:40,380 --> 01:40:43,790 -This place, the Leonard Florence Center, is wonderful. 2090 01:40:43,790 --> 01:40:50,960 They encourage you to be independent the best you can. 2091 01:40:50,960 --> 01:40:52,950 I like the attitude. 2092 01:40:56,520 --> 01:40:58,450 Hello, my name is Barbara [INAUDIBLE]. 2093 01:40:58,450 --> 01:41:01,040 I was a teacher for 29 years before I got sick. 2094 01:41:04,230 --> 01:41:05,525 I had to retire early. 2095 01:41:05,525 --> 01:41:06,562 I miss the kids. 2096 01:41:10,460 --> 01:41:11,680 I miss the nonsense. 2097 01:41:11,680 --> 01:41:15,840 -What are your typical daily activities? 2098 01:41:15,840 --> 01:41:17,520 -Some days Bingo. 2099 01:41:17,520 --> 01:41:19,348 I never played Bingo before I came here. 2100 01:41:23,710 --> 01:41:27,440 It's to socialize more. 2101 01:41:27,440 --> 01:41:32,092 I struggle with the door since my room is so small. 2102 01:41:32,092 --> 01:41:36,570 I'm in my own way with the chair, 2103 01:41:36,570 --> 01:41:41,005 so to make it so it's easier without crashing into the door. 2104 01:41:43,650 --> 01:41:46,680 The doors are very heavy for my left arm. 2105 01:41:46,680 --> 01:41:54,630 Automatic doors in the room, would be very helpful. 2106 01:41:54,630 --> 01:41:57,050 -What would be your perfect world interaction 2107 01:41:57,050 --> 01:41:59,740 with the door? 2108 01:41:59,740 --> 01:42:03,048 -I can open and close it without touching it. 2109 01:42:06,436 --> 01:42:10,308 Some of the rooms already have the technology. 2110 01:42:10,308 --> 01:42:11,276 Mine doesn't. 2111 01:42:11,276 --> 01:42:13,570 -So it's easy to open it. 2112 01:42:13,570 --> 01:42:18,905 But then once it's not moving, it's hard to do either. 2113 01:42:18,905 --> 01:42:20,600 Also, like the door will not swing open, 2114 01:42:20,600 --> 01:42:21,651 so you can't just push it because it 2115 01:42:21,651 --> 01:42:22,567 doesn't let it happen. 2116 01:42:22,567 --> 01:42:24,910 It locks itself. 2117 01:42:24,910 --> 01:42:28,320 -Then we began our design process, 2118 01:42:28,320 --> 01:42:30,570 which consisted of numerous measurements 2119 01:42:30,570 --> 01:42:32,680 on everything related to Barbara's door. 2120 01:42:36,360 --> 01:42:38,900 We then considered whether we wanted an app, button, 2121 01:42:38,900 --> 01:42:43,570 or mechanical solution and started our ideation process. 2122 01:42:43,570 --> 01:42:46,720 These ranged from an automatic collapsible door 2123 01:42:46,720 --> 01:42:54,890 that opens with a pulley, to a mechanical lever 2124 01:42:54,890 --> 01:43:02,390 that closes the door when you push on it, 2125 01:43:02,390 --> 01:43:06,082 as well as a pulley system that opens and closes the door when 2126 01:43:06,082 --> 01:43:07,275 you pull on the string. 2127 01:43:11,980 --> 01:43:16,330 And lastly, we considered an automatic soundproof curtain 2128 01:43:16,330 --> 01:43:21,930 system which would open with a touch of a button from pulleys. 2129 01:43:21,930 --> 01:43:24,840 We decided to pursue the curtain idea, 2130 01:43:24,840 --> 01:43:27,930 and are now beginning to prototype over and over 2131 01:43:27,930 --> 01:43:32,030 and over again until we create the perfect automatic door. 2132 01:43:39,680 --> 01:43:42,255 STUDENT 2: So that's just an overview of our design process. 2133 01:43:42,255 --> 01:43:44,630 So I'm going to take you through the specifics of it now. 2134 01:43:47,490 --> 01:43:50,542 So these are the three idea that we were pursuing for the door. 2135 01:43:50,542 --> 01:43:52,000 And the first thing that we did was 2136 01:43:52,000 --> 01:43:55,876 weigh the pros and cons of each possibility. 2137 01:43:55,876 --> 01:43:57,500 So with the automatic collapsible door, 2138 01:43:57,500 --> 01:43:59,680 we thought that this would serve as a good alternative 2139 01:43:59,680 --> 01:44:01,200 because it's rigid, so it does still 2140 01:44:01,200 --> 01:44:03,550 have the appearance of a door. 2141 01:44:03,550 --> 01:44:05,340 But some issues we had with is that it 2142 01:44:05,340 --> 01:44:08,260 was hard to find the parts to create a rigid collapsible 2143 01:44:08,260 --> 01:44:13,220 door that was cheap and easy to put together. 2144 01:44:13,220 --> 01:44:16,430 Next, we considered automatic curtains, which we thought 2145 01:44:16,430 --> 01:44:19,430 would be very easy to implement and test, 2146 01:44:19,430 --> 01:44:21,580 and we get soundproof curtains that could 2147 01:44:21,580 --> 01:44:23,180 implement that part of it. 2148 01:44:23,180 --> 01:44:26,510 But one issue is that it might not be door-like enough 2149 01:44:26,510 --> 01:44:29,860 and fit in with like the norms of what doors simply look like, 2150 01:44:29,860 --> 01:44:33,850 and the pulley system could get stuck as well. 2151 01:44:33,850 --> 01:44:36,370 Lastly, we considered a mechanical lever and pulley 2152 01:44:36,370 --> 01:44:40,180 system, so this would alter the door itself, 2153 01:44:40,180 --> 01:44:42,990 so we wouldn't have any extra parts, 2154 01:44:42,990 --> 01:44:45,920 and it should make the whole thing flow a little bit more 2155 01:44:45,920 --> 01:44:46,420 smoothly. 2156 01:44:46,420 --> 01:44:47,878 But it's kind of hard to implement, 2157 01:44:47,878 --> 01:44:51,465 as we are not mechanical engineering students. 2158 01:44:51,465 --> 01:44:53,340 So we decided to go with the middle approach, 2159 01:44:53,340 --> 01:44:57,822 as it is very easy to test and prototype. 2160 01:44:57,822 --> 01:44:59,780 But when we went to the Leonard Florence Center 2161 01:44:59,780 --> 01:45:03,860 with our idea to see if there were any issues, 2162 01:45:03,860 --> 01:45:05,760 we found that there were a lot. 2163 01:45:05,760 --> 01:45:08,340 One of the first ones is that they consider curtains 2164 01:45:08,340 --> 01:45:11,700 a major fire hazard because she could get stuck, 2165 01:45:11,700 --> 01:45:15,650 or the curtains could get in the way of her leaving or entering 2166 01:45:15,650 --> 01:45:16,210 her room. 2167 01:45:18,820 --> 01:45:21,220 They also told is that this idea must be fail proof. 2168 01:45:21,220 --> 01:45:24,600 So if there were a fire, the door must be able to close, 2169 01:45:24,600 --> 01:45:27,529 and nothing should inhibit its way. 2170 01:45:27,529 --> 01:45:29,320 So we tried to brainstorm another solution, 2171 01:45:29,320 --> 01:45:31,840 and decided to go with our mechanical approach. 2172 01:45:31,840 --> 01:45:34,440 But there we found that if we connected it 2173 01:45:34,440 --> 01:45:41,210 with the fire alarm system, we could get our pulley 2174 01:45:41,210 --> 01:45:45,035 to dislodge from the door if the fire alarm system goes off. 2175 01:45:45,035 --> 01:45:46,410 And then this would hopefully not 2176 01:45:46,410 --> 01:45:48,610 in impede with the door's mechanism 2177 01:45:48,610 --> 01:45:50,860 when there is a fire alarm. 2178 01:45:50,860 --> 01:45:55,160 But still they raised the problems of a fire hazard, that 2179 01:45:55,160 --> 01:45:57,270 must be fail proof, and they also did not really 2180 01:45:57,270 --> 01:46:00,910 understand how we would connect our new door system 2181 01:46:00,910 --> 01:46:03,210 to the main system itself. 2182 01:46:03,210 --> 01:46:06,030 And if we were to go through the peak system that is currently 2183 01:46:06,030 --> 01:46:09,640 at the Leonard Florence Center, it's super expensive. 2184 01:46:09,640 --> 01:46:14,680 And so we found it this idea is not very feasible for us. 2185 01:46:14,680 --> 01:46:18,790 So this led us to work into her secondary problem, which 2186 01:46:18,790 --> 01:46:20,100 is light automation. 2187 01:46:20,100 --> 01:46:24,680 So the reason why this was her secondary preferences it's she, 2188 01:46:24,680 --> 01:46:26,920 with third condition of PLS, she actually 2189 01:46:26,920 --> 01:46:30,030 can't get up from her bed to shut off the light before she 2190 01:46:30,030 --> 01:46:30,920 goes to bed. 2191 01:46:30,920 --> 01:46:32,980 So she has to call a nurse to do so. 2192 01:46:32,980 --> 01:46:35,900 So this impedes on her independence. 2193 01:46:35,900 --> 01:46:37,350 This happens every day. 2194 01:46:37,350 --> 01:46:39,510 So this would be a problem that if we could solve, 2195 01:46:39,510 --> 01:46:42,570 it would help frequently, so she'd 2196 01:46:42,570 --> 01:46:45,100 be able to have very good use of it. 2197 01:46:45,100 --> 01:46:46,950 It's not like a one-case scenario. 2198 01:46:46,950 --> 01:46:49,810 And this will also help her because in the future, when 2199 01:46:49,810 --> 01:46:51,620 she is in a wheelchair, she may not 2200 01:46:51,620 --> 01:46:53,890 be able to have the strength to reach up 2201 01:46:53,890 --> 01:46:55,735 to the light to switch. 2202 01:46:55,735 --> 01:46:59,810 Whereas with an application, she could, since PLS 2203 01:46:59,810 --> 01:47:00,530 is progressive. 2204 01:47:00,530 --> 01:47:04,100 So as a condition worsens this would be one of the this 2205 01:47:04,100 --> 01:47:06,540 will be a possible solution that can like at least 2206 01:47:06,540 --> 01:47:09,540 allow her to shut off the light when she wants to, 2207 01:47:09,540 --> 01:47:13,040 and she's not in her bed for a longer period of time. 2208 01:47:13,040 --> 01:47:23,170 So different processes we thought of doing this, 2209 01:47:23,170 --> 01:47:24,820 we thought of using X10. 2210 01:47:24,820 --> 01:47:28,150 So while we were searching, we found X10, 2211 01:47:28,150 --> 01:47:33,380 so it's possible through Wi-Fi to send a signal to the X10 2212 01:47:33,380 --> 01:47:34,580 transceiver. 2213 01:47:34,580 --> 01:47:36,970 That sends a message to the outlet 2214 01:47:36,970 --> 01:47:40,250 through electricity, some sort of like Morse code 2215 01:47:40,250 --> 01:47:43,780 for electricity kind of, to give an idea of what it's doing. 2216 01:47:43,780 --> 01:47:46,670 And then that can be used to turn on or off the light. 2217 01:47:46,670 --> 01:47:50,020 So the process would be a little straight forward, 2218 01:47:50,020 --> 01:47:52,230 since the products are available. 2219 01:47:52,230 --> 01:47:54,270 It would just be us connecting them, 2220 01:47:54,270 --> 01:47:57,880 and then the actual application already exists. 2221 01:47:57,880 --> 01:48:00,960 And the price tag was about $100. 2222 01:48:00,960 --> 01:48:03,330 Another idea we thought of was a more hands 2223 01:48:03,330 --> 01:48:07,750 on approach of getting in Arduino to send a radio 2224 01:48:07,750 --> 01:48:09,600 frequency signal to the light. 2225 01:48:09,600 --> 01:48:14,440 We could buy the light that have as a receiver for this radio 2226 01:48:14,440 --> 01:48:16,020 frequency signal. 2227 01:48:16,020 --> 01:48:18,370 So then we would basically send a Bluetooth signal 2228 01:48:18,370 --> 01:48:23,130 from her phone to the Arduino [? BLE ?] shield, 2229 01:48:23,130 --> 01:48:25,750 and then that would send the signal 2230 01:48:25,750 --> 01:48:27,650 to the corresponding light. 2231 01:48:27,650 --> 01:48:29,820 So this was an option that we could also 2232 01:48:29,820 --> 01:48:31,820 have that basically we just have to have 2233 01:48:31,820 --> 01:48:36,910 multiple receivers, radio frequency receivers that 2234 01:48:36,910 --> 01:48:38,600 are on the bottom right hand corner. 2235 01:48:38,600 --> 01:48:40,330 So then she could send different signals 2236 01:48:40,330 --> 01:48:43,790 from her phone to control each and every light independently. 2237 01:48:43,790 --> 01:48:45,530 So it was an approach we thought of. 2238 01:48:45,530 --> 01:48:48,094 The price tag on it was about $70 2239 01:48:48,094 --> 01:48:50,510 because we would have to have the [? BLE ?] shield as well 2240 01:48:50,510 --> 01:48:51,640 as the Arduino. 2241 01:48:51,640 --> 01:48:54,150 And then the outlet, the receiver, 2242 01:48:54,150 --> 01:48:55,490 was also a little bit of cash. 2243 01:49:01,480 --> 01:49:04,720 So then after that we like started 2244 01:49:04,720 --> 01:49:08,040 trying to come up with how we were going to do this. 2245 01:49:08,040 --> 01:49:10,210 And our next idea was WeMo. 2246 01:49:10,210 --> 01:49:11,520 We saw this online. 2247 01:49:11,520 --> 01:49:14,280 Basically, they have their own solution for it. 2248 01:49:14,280 --> 01:49:17,377 Basically, you can connect to it through an application 2249 01:49:17,377 --> 01:49:18,710 that they already have provided. 2250 01:49:18,710 --> 01:49:22,080 The application is free, and the product actually costs $41. 2251 01:49:22,080 --> 01:49:26,740 So we thought of having this implemented in her system 2252 01:49:26,740 --> 01:49:30,200 and then possibly expanding the SDK for the application 2253 01:49:30,200 --> 01:49:34,270 so that she could have an easier time using it, 2254 01:49:34,270 --> 01:49:36,117 and then have it basically tailored to her 2255 01:49:36,117 --> 01:49:38,075 so that she only had to look at the application 2256 01:49:38,075 --> 01:49:43,465 and touch larger buttons since the buttons are 2257 01:49:43,465 --> 01:49:46,560 a little smaller than we would hope. 2258 01:49:46,560 --> 01:49:48,450 Possible next steps is what I just 2259 01:49:48,450 --> 01:49:51,490 said, where we expand an application based 2260 01:49:51,490 --> 01:49:55,730 off the SDK for WeMo and make that app available for her. 2261 01:49:55,730 --> 01:49:59,850 Or if this ends up being a solution right of the shell, 2262 01:49:59,850 --> 01:50:02,730 then we could possibly taken an avenue where 2263 01:50:02,730 --> 01:50:05,730 after fixing this light problem with WeMo, 2264 01:50:05,730 --> 01:50:08,770 go into the voice applications so try and see 2265 01:50:08,770 --> 01:50:10,670 if we can tailor voice application for her. 2266 01:50:15,050 --> 01:50:17,150 So our timeline is by the end of October, 2267 01:50:17,150 --> 01:50:19,045 we hope to have WeMo installed. 2268 01:50:19,045 --> 01:50:21,230 The first half of November we hope 2269 01:50:21,230 --> 01:50:25,940 to prototype the like UI for either the voice app, 2270 01:50:25,940 --> 01:50:29,110 also, possibly, if necessary, the light app. 2271 01:50:29,110 --> 01:50:32,690 Second half, we would like to have this app done in iOS. 2272 01:50:32,690 --> 01:50:35,370 The reason for prototyping [INAUDIBLE] it's faster, 2273 01:50:35,370 --> 01:50:37,625 and we can get a lot of the UI feel really quickly. 2274 01:50:37,625 --> 01:50:39,000 And then after that we would just 2275 01:50:39,000 --> 01:50:40,920 keep testing and iterating until we have a product that 2276 01:50:40,920 --> 01:50:41,920 fits Barbara's needs. 2277 01:50:47,597 --> 01:50:48,180 Any questions? 2278 01:50:53,330 --> 01:50:55,080 PROFESSOR 1: Could you say a bit about how 2279 01:50:55,080 --> 01:50:57,371 you're going to divide the work among the three of you? 2280 01:50:57,371 --> 01:51:02,190 STUDENT 3: OK, so in terms of the work for the door, 2281 01:51:02,190 --> 01:51:04,050 we've been all going to the center 2282 01:51:04,050 --> 01:51:05,850 to speak with as many people as possible. 2283 01:51:05,850 --> 01:51:07,760 So for the time being, it's been a lot 2284 01:51:07,760 --> 01:51:11,360 of contextual inquiry and a lot like designing all together. 2285 01:51:11,360 --> 01:51:16,800 But in terms of the next steps for installing the WeMo, 2286 01:51:16,800 --> 01:51:18,780 we were going to go to the center together 2287 01:51:18,780 --> 01:51:21,840 and while two of the members were 2288 01:51:21,840 --> 01:51:24,260 going to be working on installing this in the room, 2289 01:51:24,260 --> 01:51:26,570 we were also going to continue to ask about the door, 2290 01:51:26,570 --> 01:51:28,589 we are pushing towards like at least speaking 2291 01:51:28,589 --> 01:51:30,630 to a lot of members in the center about the door, 2292 01:51:30,630 --> 01:51:32,338 since that is an issue that we would hope 2293 01:51:32,338 --> 01:51:34,330 would be solved in the future. 2294 01:51:34,330 --> 01:51:37,110 After that is installed, the dividing the actual application 2295 01:51:37,110 --> 01:51:42,200 process, so since we, as a team, don't all 2296 01:51:42,200 --> 01:51:44,840 have like skills in App Inventor and iOS, 2297 01:51:44,840 --> 01:51:46,960 we were going to divide up so that we would end up 2298 01:51:46,960 --> 01:51:49,610 having some of the base code that would definitely 2299 01:51:49,610 --> 01:51:51,870 be necessary for iOS built right from the beginning 2300 01:51:51,870 --> 01:51:54,460 while the UI is being prototyping in App Inventor. 2301 01:51:54,460 --> 01:51:56,740 So in terms of like team specific, 2302 01:51:56,740 --> 01:52:00,080 it would be two members working on the iOS application, 2303 01:52:00,080 --> 01:52:02,650 while one member just continually prototypes 2304 01:52:02,650 --> 01:52:05,170 the ideas that the team comes up with in App Inventory 2305 01:52:05,170 --> 01:52:07,210 to like give a feel for it. 2306 01:52:07,210 --> 01:52:11,100 We would always go as a team to show this to Barbara. 2307 01:52:11,100 --> 01:52:14,840 And then once the App Inventor UI decision is made, 2308 01:52:14,840 --> 01:52:16,730 we would all be working on the iOS apps 2309 01:52:16,730 --> 01:52:18,813 since that's going to be the majority of the part. 2310 01:52:21,850 --> 01:52:24,567 Any other questions? 2311 01:52:24,567 --> 01:52:26,025 PROFESSOR 5: So basically, the door 2312 01:52:26,025 --> 01:52:27,592 is sort of too hard is basically-- 2313 01:52:27,592 --> 01:52:28,550 it's just not workable? 2314 01:52:29,714 --> 01:52:31,880 STUDENT 2: There a lot of regulations with the door. 2315 01:52:31,880 --> 01:52:33,546 We'd have to get it approved by the fire 2316 01:52:33,546 --> 01:52:35,880 department, the public health department, and the people 2317 01:52:35,880 --> 01:52:37,504 at the center, a lot of them don't even 2318 01:52:37,504 --> 01:52:39,680 know how it functions and how it connects up 2319 01:52:39,680 --> 01:52:43,110 to like the central system that closes all the doors when 2320 01:52:43,110 --> 01:52:44,570 a fire alarm goes off. 2321 01:52:44,570 --> 01:52:46,695 So it would require a lot more research, 2322 01:52:46,695 --> 01:52:48,570 and we're not sure if it's feasible to finish 2323 01:52:48,570 --> 01:52:51,560 this project in the next two or three months that we have. 2324 01:52:59,501 --> 01:53:01,000 JESSICA HERRING: So we are Team Art. 2325 01:53:01,000 --> 01:53:01,500 I'm Jessica. 2326 01:53:02,055 --> 01:53:03,013 RACHEL ELLISON: Rachel. 2327 01:53:04,009 --> 01:53:05,300 STEPHANIE CHEN : I'm Stephanie. 2328 01:53:05,300 --> 01:53:07,383 JESSICA HERRING: And what we have decided to build 2329 01:53:07,383 --> 01:53:09,340 is a power lift. 2330 01:53:09,340 --> 01:53:11,260 So first, we're going to introduce our client. 2331 01:53:11,260 --> 01:53:12,810 His name is Art. 2332 01:53:12,810 --> 01:53:15,670 He is an adaptive rock climber, a hacker, a tinkerer. 2333 01:53:15,670 --> 01:53:19,400 He likes to build stuff-- adapt stuff 2334 01:53:19,400 --> 01:53:22,150 to his specifications and his desires, 2335 01:53:22,150 --> 01:53:24,950 and he's a very active member of his community. 2336 01:53:24,950 --> 01:53:28,470 He has a girlfriend, and she works in his hacker space 2337 01:53:28,470 --> 01:53:30,440 at the Artisans Asylum in Somerville, 2338 01:53:30,440 --> 01:53:33,660 which is pretty much a hacker space, where 2339 01:53:33,660 --> 01:53:35,850 people build stuff. 2340 01:53:35,850 --> 01:53:39,430 However, he has T5 Asia B Paraplegia, which 2341 01:53:39,430 --> 01:53:41,990 is an incomplete paraplegic. 2342 01:53:41,990 --> 01:53:45,730 So he has some sensory function below his waist, 2343 01:53:45,730 --> 01:53:47,910 but no motor function. 2344 01:53:47,910 --> 01:53:51,480 In addition to this, he has a grade 2 shoulder separation 2345 01:53:51,480 --> 01:53:54,209 that is not quite bad enough to need surgery, 2346 01:53:54,209 --> 01:53:56,500 but we do want to consider this when making our design. 2347 01:53:56,500 --> 01:54:01,450 We don't want to make our mechanisms too manual. 2348 01:54:01,450 --> 01:54:04,190 So Art wants to be able to work on the floor. 2349 01:54:04,190 --> 01:54:08,250 He wants to be able to get under some of his bigger projects, 2350 01:54:08,250 --> 01:54:11,379 like he'll lift up a wheelchair on his lift that he's designed, 2351 01:54:11,379 --> 01:54:12,670 and he'll want to get under it. 2352 01:54:12,670 --> 01:54:13,910 But it's really hard to do that when 2353 01:54:13,910 --> 01:54:15,326 you're getting out of a wheelchair 2354 01:54:15,326 --> 01:54:16,880 and you can't move your legs. 2355 01:54:16,880 --> 01:54:20,120 So, in addition to that, if you were to fall out of his chair, 2356 01:54:20,120 --> 01:54:22,706 he would like to be able to use something to get back up 2357 01:54:22,706 --> 01:54:23,702 alone independently. 2358 01:54:23,702 --> 01:54:27,686 [VIDEO PLAYBACK] 2359 01:54:47,606 --> 01:54:52,088 -Well, I'm a [INAUDIBLE] minded person, a lot of independence. 2360 01:54:52,088 --> 01:54:59,060 Before I got hurt in March of 2010, 2361 01:54:59,060 --> 01:55:02,046 I was the person who took care of all of our household 2362 01:55:02,046 --> 01:55:02,546 maintenance. 2363 01:55:02,546 --> 01:55:05,534 I did a lot of motorcycle repair. 2364 01:55:05,534 --> 01:55:08,024 [INAUDIBLE] 2365 01:55:08,024 --> 01:55:12,506 Pretty much [INAUDIBLE], I worked on it. 2366 01:55:12,506 --> 01:55:15,010 Now, I still try to do as much of that as I can. 2367 01:55:15,010 --> 01:55:18,344 We're filming this at Artisan's Asylum, which 2368 01:55:18,344 --> 01:55:21,180 is one of the world's largest hacker spaces, 2369 01:55:21,180 --> 01:55:23,319 maker spaces and collaborative workshops 2370 01:55:23,319 --> 01:55:26,630 that anyone [INAUDIBLE]. 2371 01:55:26,630 --> 01:55:32,889 We have shops that cover an incredibly wide range of skills 2372 01:55:32,889 --> 01:55:33,847 and technology. 2373 01:55:38,650 --> 01:55:42,090 What they call a T-5 Asia B, which basically means that 2374 01:55:42,090 --> 01:55:46,887 from about here down I have no motor function. 2375 01:55:46,887 --> 01:55:48,970 Because I can't get in and out of my chair easily, 2376 01:55:48,970 --> 01:55:51,742 I'm more or less limited to doing things 2377 01:55:51,742 --> 01:55:52,866 that I can sit in front of. 2378 01:56:33,702 --> 01:56:44,658 [END PLAYBACK] 2379 01:56:44,658 --> 01:56:47,148 JESSICA HERRING: He is quite a character, 2380 01:56:47,148 --> 01:56:51,230 and he's very specific about he wants. 2381 01:56:51,230 --> 01:56:54,170 But we figure that we can help him out with that. 2382 01:56:54,170 --> 01:56:56,536 So our goal is to design something that's portable, 2383 01:56:56,536 --> 01:56:58,240 something that's lightweight, something 2384 01:56:58,240 --> 01:57:00,870 that is about the height of his chair 2385 01:57:00,870 --> 01:57:04,600 that he can get in and out of and get up and down with. 2386 01:57:04,600 --> 01:57:07,860 So the height of the wheelchair seat-- Art cat 2387 01:57:07,860 --> 01:57:12,230 only move about three or four inches vertically by himself. 2388 01:57:12,230 --> 01:57:14,690 And so we need our device to be about the height 2389 01:57:14,690 --> 01:57:17,400 of his wheelchair seat, which is 22 inches tall, 2390 01:57:17,400 --> 01:57:20,420 but we'd also like it to be used anywhere he wants to use it. 2391 01:57:20,420 --> 01:57:23,520 So we originally wanted him to be able to take it with him, 2392 01:57:23,520 --> 01:57:25,970 and that's still one of our goals. 2393 01:57:25,970 --> 01:57:28,300 We also need it to weigh under 20 pounds. 2394 01:57:28,300 --> 01:57:29,990 This is because he wants his girlfriend 2395 01:57:29,990 --> 01:57:32,365 to be able to take it to him if he falls out of his chair 2396 01:57:32,365 --> 01:57:34,430 and needs it or for some other reason. 2397 01:57:34,430 --> 01:57:36,150 His girlfriend can only lift 20 pounds 2398 01:57:36,150 --> 01:57:39,700 because she has a medical condition that restricts that. 2399 01:57:39,700 --> 01:57:43,170 So our major success metric is time. 2400 01:57:43,170 --> 01:57:44,600 A lot of these design constraints 2401 01:57:44,600 --> 01:57:48,310 will make or break the project, but the time is a variable. 2402 01:57:48,310 --> 01:57:51,510 So we would like it to be approximately one minute. 2403 01:57:51,510 --> 01:57:53,780 Art wanted something a little more like 30 seconds 2404 01:57:53,780 --> 01:57:56,161 to 45 seconds, but we think a minute would also be OK. 2405 01:58:00,640 --> 01:58:03,580 STEPHANIE CHEN : So after taking these design limitations 2406 01:58:03,580 --> 01:58:06,510 into account, we decided to look into products that were 2407 01:58:06,510 --> 01:58:08,030 commercially available. 2408 01:58:08,030 --> 01:58:18,340 So at first, we began looking into commercially available 2409 01:58:18,340 --> 01:58:19,360 medical technology. 2410 01:58:19,360 --> 01:58:21,350 For example, that up there is something called 2411 01:58:21,350 --> 01:58:23,020 an [? elk ?] emergency lift. 2412 01:58:23,020 --> 01:58:27,510 It's probably the most ideal out of these products 2413 01:58:27,510 --> 01:58:30,770 for our client because it weighs approximately five pounds 2414 01:58:30,770 --> 01:58:33,330 and it can support 1,000 pounds. 2415 01:58:33,330 --> 01:58:37,820 The only problem with it is that it costs $3,000 at least, 2416 01:58:37,820 --> 01:58:42,190 and there's no guaranteed stability if he's actually 2417 01:58:42,190 --> 01:58:43,130 lifting in the chair. 2418 01:58:43,130 --> 01:58:46,380 There's nothing preventing them from falling to the side. 2419 01:58:46,380 --> 01:58:48,320 And just for fun, we decided to look 2420 01:58:48,320 --> 01:58:50,886 into other types of lifting cushions 2421 01:58:50,886 --> 01:58:52,380 available in other industries. 2422 01:58:52,380 --> 01:58:54,980 We actually found something called the Map Jack, which 2423 01:58:54,980 --> 01:58:56,160 is something similar. 2424 01:58:56,160 --> 01:59:01,680 It costs about $800, and it can lift probably six tons-- 2425 01:59:01,680 --> 01:59:03,330 fun fact. 2426 01:59:03,330 --> 01:59:07,090 We then decided to look into the idea of a scissor lift, which 2427 01:59:07,090 --> 01:59:11,415 is a relatively prevalent lifting mechanism. 2428 01:59:11,415 --> 01:59:15,240 You can find it in construction sites and warehouses and so on. 2429 01:59:15,240 --> 01:59:18,450 The problem with that idea is that there 2430 01:59:18,450 --> 01:59:22,670 is a lot of friction losses associated with scissor lifts, 2431 01:59:22,670 --> 01:59:25,471 and considering the fact that none of us 2432 01:59:25,471 --> 01:59:27,729 are mechanical engineers, we decided 2433 01:59:27,729 --> 01:59:29,770 it would be best if we started off with something 2434 01:59:29,770 --> 01:59:30,580 a little simpler. 2435 01:59:30,580 --> 01:59:34,170 And actually, if we consider the weight of a scissor lift 2436 01:59:34,170 --> 01:59:39,890 into account, it would certainly weigh more than 20 pounds. 2437 01:59:39,890 --> 01:59:44,470 We then decided to look into a pool lift, which Art actually 2438 01:59:44,470 --> 01:59:45,110 owns. 2439 01:59:45,110 --> 01:59:49,160 The main issue with this idea is that unfortunately it's 2440 01:59:49,160 --> 01:59:55,060 stationary, and we require a very powerful linear actuator, 2441 01:59:55,060 --> 01:59:56,780 so we decided to scrap those ideas. 2442 01:59:59,840 --> 02:00:02,070 One idea that we actually came across 2443 02:00:02,070 --> 02:00:06,020 is something similar to one of those stair lifts. 2444 02:00:06,020 --> 02:00:07,720 It's essentially a sliding lift. 2445 02:00:07,720 --> 02:00:10,440 It'll bring someone who's not capable of going to upstairs 2446 02:00:10,440 --> 02:00:14,390 from the bottom to the top of their staircase. 2447 02:00:14,390 --> 02:00:17,400 And Art was actually in preference of this idea. 2448 02:00:17,400 --> 02:00:22,960 As you can see, based on the lower sketch, 2449 02:00:22,960 --> 02:00:24,890 it appears to be relatively light design. 2450 02:00:24,890 --> 02:00:28,210 And it's incredibly portable because it essentially 2451 02:00:28,210 --> 02:00:30,450 looked like a tripod. 2452 02:00:30,450 --> 02:00:34,480 And unfortunately, the major disadvantages of this 2453 02:00:34,480 --> 02:00:40,200 is we, again, have to deal with a lot of friction losses, 2454 02:00:40,200 --> 02:00:41,920 and we also have to include a bunch 2455 02:00:41,920 --> 02:00:44,140 of fail safes such as hand brakes, 2456 02:00:44,140 --> 02:00:48,630 just to ensure that he doesn't accidentally slide down when 2457 02:00:48,630 --> 02:00:52,921 he's near the top of the ramp. 2458 02:00:52,921 --> 02:00:54,420 And for this design we actually need 2459 02:00:54,420 --> 02:00:57,180 a very specialized motor, something that's low speed 2460 02:00:57,180 --> 02:00:59,790 and high in torque. 2461 02:00:59,790 --> 02:01:06,300 One idea that-- so this is actually our 2462 02:01:06,300 --> 02:01:08,280 currently most worked done idea. 2463 02:01:08,280 --> 02:01:10,550 It's a screw lift essentially. 2464 02:01:10,550 --> 02:01:15,550 And that is a smaller scale prototype. 2465 02:01:15,550 --> 02:01:19,070 Based on this drawing, you can see that we essentially 2466 02:01:19,070 --> 02:01:23,390 take multiple 80-20 rods and arrange them 2467 02:01:23,390 --> 02:01:26,310 in that sort of fashion, so you have one rod on this side 2468 02:01:26,310 --> 02:01:30,210 and one rod on the other, where there's a seat in the middle. 2469 02:01:30,210 --> 02:01:32,990 And in between those two rods, and what's holding up 2470 02:01:32,990 --> 02:01:34,770 the chair, is a threaded rod. 2471 02:01:34,770 --> 02:01:37,650 So essentially we'd be using either 2472 02:01:37,650 --> 02:01:41,220 a drill motor or any sort of motor 2473 02:01:41,220 --> 02:01:45,880 to twist that threaded rod to lift or to cause 2474 02:01:45,880 --> 02:01:48,290 the chair to ascend or descend. 2475 02:01:48,290 --> 02:01:49,780 The major advantage to this is it 2476 02:01:49,780 --> 02:01:52,977 can be designed to be rather foldable, 2477 02:01:52,977 --> 02:01:54,810 and we don't have to build in any fail safes 2478 02:01:54,810 --> 02:01:57,440 because we're dealing with a threaded rod. 2479 02:01:57,440 --> 02:02:01,500 And actually, the motors required for this design 2480 02:02:01,500 --> 02:02:03,600 are also relatively cheaper. 2481 02:02:03,600 --> 02:02:06,490 But the major disadvantages to this idea, 2482 02:02:06,490 --> 02:02:10,360 in particular, is that we have to work with multiple parts, 2483 02:02:10,360 --> 02:02:14,190 and this could be a potentially heavy idea. 2484 02:02:17,690 --> 02:02:21,350 So here is actually a video of the prototype. 2485 02:02:53,105 --> 02:02:54,980 RACHEL ELLISON: So this showing it does move. 2486 02:02:54,980 --> 02:02:56,105 This me turning it by hand. 2487 02:02:56,105 --> 02:03:01,100 And so if you're turning it at maybe 100, 150, 2488 02:03:01,100 --> 02:03:03,520 it would be moving a lot faster. 2489 02:03:03,520 --> 02:03:08,260 The [INAUDIBLE] we're looking at are eight turns per inch. 2490 02:03:08,260 --> 02:03:13,102 So at 22 inches, we are looking at about 200 turns. 2491 02:03:19,060 --> 02:03:21,480 So the next steps in our process really 2492 02:03:21,480 --> 02:03:24,780 are to expand on these two ideas and decide 2493 02:03:24,780 --> 02:03:28,110 which design to pursue. 2494 02:03:28,110 --> 02:03:30,090 Stephanie is handing around now 80-20 2495 02:03:30,090 --> 02:03:33,420 rod, which is the basis of our sliding mechanism. 2496 02:03:33,420 --> 02:03:35,350 And really what we're trying to do 2497 02:03:35,350 --> 02:03:36,970 is understand what parts we'll be 2498 02:03:36,970 --> 02:03:39,980 able to get within our budget constraints 2499 02:03:39,980 --> 02:03:43,180 and which one will provide a lighter weight 2500 02:03:43,180 --> 02:03:45,980 design that fits more of our design specifications. 2501 02:03:45,980 --> 02:03:48,610 We'd like it to be full scale, our next prototype, 2502 02:03:48,610 --> 02:03:52,780 and we're going to prioritize durability and sturdiness. 2503 02:03:52,780 --> 02:03:56,760 After that, we'd like to make a more polished prototype 2504 02:03:56,760 --> 02:03:58,250 of our final idea. 2505 02:03:58,250 --> 02:04:00,780 We'd like this one to fold up to be transportable 2506 02:04:00,780 --> 02:04:02,744 and to be within our weight specifications. 2507 02:04:02,744 --> 02:04:04,160 For our first prototype, we're not 2508 02:04:04,160 --> 02:04:06,564 going to worry so much about that. 2509 02:04:06,564 --> 02:04:08,230 We'd like to try to optimize the lifting 2510 02:04:08,230 --> 02:04:10,430 time and the speed at which the motor turns 2511 02:04:10,430 --> 02:04:12,012 to lift Art up and down. 2512 02:04:12,012 --> 02:04:14,220 And finally, we'd like to think about the feasibility 2513 02:04:14,220 --> 02:04:16,000 of mass production of this device 2514 02:04:16,000 --> 02:04:18,440 and what is going into it and whether those things will 2515 02:04:18,440 --> 02:04:21,460 be available for other users. 2516 02:04:21,460 --> 02:04:24,851 And so our projected costs with the slider design 2517 02:04:24,851 --> 02:04:26,600 which is a little bit more expensive we're 2518 02:04:26,600 --> 02:04:29,380 going to need a linear bearing to slide up and down the broad 2519 02:04:29,380 --> 02:04:32,040 with hand brake built in so that it will be 2520 02:04:32,040 --> 02:04:34,000 stable at the top of the ramp. 2521 02:04:34,000 --> 02:04:36,060 And that's about $65. 2522 02:04:36,060 --> 02:04:38,030 For a high torque, low speed motor, 2523 02:04:38,030 --> 02:04:41,870 those are pretty pricey and come at $60 to $80 new. 2524 02:04:41,870 --> 02:04:44,320 We've been looking into scavenging this part 2525 02:04:44,320 --> 02:04:46,590 to try to cut down costs. 2526 02:04:46,590 --> 02:04:49,020 We'll also need other parts, such as hinges and legs, 2527 02:04:49,020 --> 02:04:51,190 so that'll fold up. 2528 02:04:51,190 --> 02:04:53,840 For the screw lift design, we're looking 2529 02:04:53,840 --> 02:04:59,230 at using a threaded rod, and this Acme thread design 2530 02:04:59,230 --> 02:05:01,590 is a special kind of threading designed to bear weight 2531 02:05:01,590 --> 02:05:05,330 and not snag so that we can turn it hopefully at higher speeds. 2532 02:05:05,330 --> 02:05:07,520 We'll also need a low torque, higher speed motor. 2533 02:05:07,520 --> 02:05:09,019 Those will be significantly cheaper, 2534 02:05:09,019 --> 02:05:12,266 and actually we have several of those on hand right now. 2535 02:05:12,266 --> 02:05:13,640 And the rest of the lift is going 2536 02:05:13,640 --> 02:05:16,060 to be aluminum or wooden parts which can 2537 02:05:16,060 --> 02:05:18,480 come from the hardware store. 2538 02:05:18,480 --> 02:05:21,260 So with that, I'd like to thank teammates Jessica, who's 2539 02:05:21,260 --> 02:05:23,850 been in charge of videotaping our meetings 2540 02:05:23,850 --> 02:05:27,340 and edited both the lovely videos you saw earlier, 2541 02:05:27,340 --> 02:05:29,580 Stephanie, who's been heading up our prototyping 2542 02:05:29,580 --> 02:05:33,120 and is going to be doing a lot of stuff 2543 02:05:33,120 --> 02:05:34,696 with building in the next few weeks, 2544 02:05:34,696 --> 02:05:36,320 and then I'm not going to thank myself, 2545 02:05:36,320 --> 02:05:38,920 but I've been doing a lot of the interviewing and client 2546 02:05:38,920 --> 02:05:40,760 communication. 2547 02:05:40,760 --> 02:05:43,147 We'd also like to give a special thanks to Don Fredette 2548 02:05:43,147 --> 02:05:44,730 at The Boston House, who's provided us 2549 02:05:44,730 --> 02:05:48,180 with a lot of guidance, parts, moral support, Joseph 2550 02:05:48,180 --> 02:05:50,360 Parse, in the Department of Material Science 2551 02:05:50,360 --> 02:05:52,860 and Engineering, who helped us figure out the screw lift 2552 02:05:52,860 --> 02:05:55,790 design and what parts we'd need to make it work, 2553 02:05:55,790 --> 02:05:58,200 and finally our client himself has helped us 2554 02:05:58,200 --> 02:06:01,610 a lot with the design feasibility and sourcing parts, 2555 02:06:01,610 --> 02:06:04,110 and since he works at this hacker space, 2556 02:06:04,110 --> 02:06:06,250 he's also volunteered to help us put it together, 2557 02:06:06,250 --> 02:06:08,625 and, of course, the PPAT staff makes this class possible. 2558 02:06:10,892 --> 02:06:11,475 Any questions? 2559 02:06:15,343 --> 02:06:17,634 PROFESSOR 4: We have about three minutes for questions. 2560 02:06:20,198 --> 02:06:22,406 PROFESSOR 4: Have you looked at Kiva Systems, a robot 2561 02:06:22,406 --> 02:06:23,455 for warehouse automation? 2562 02:06:23,455 --> 02:06:25,867 They were bought for $600 million 2563 02:06:25,867 --> 02:06:27,620 by Amazon a couple years ago. 2564 02:06:27,620 --> 02:06:30,080 But they have a lift, a clever lift mechanism. 2565 02:06:30,080 --> 02:06:33,897 Their founder talked to [? Mickey ?] last week. 2566 02:06:33,897 --> 02:06:35,480 Maybe I can give you a pointer or two. 2567 02:06:35,480 --> 02:06:36,710 They have a clever design. 2568 02:06:36,710 --> 02:06:37,543 Maybe it's the same. 2569 02:06:41,020 --> 02:06:43,975 But I do worry about the overall electromechanical robustness. 2570 02:06:46,980 --> 02:06:50,200 Have you thought about how the whole-- the power, 2571 02:06:50,200 --> 02:06:54,587 the connectors, the control everything puts together? 2572 02:06:54,587 --> 02:06:56,920 RACHEL ELLISON: We should have said something about this 2573 02:06:56,920 --> 02:06:59,350 during the presentation, but Art has 2574 02:06:59,350 --> 02:07:03,870 hacked into 24 volt battery system in his chair 2575 02:07:03,870 --> 02:07:05,910 and has an Anderson volt connector that we 2576 02:07:05,910 --> 02:07:07,325 can use to power our devices. 2577 02:07:07,325 --> 02:07:10,917 PROFESSOR 4: So you'll connect in to the wheelchair battery. 2578 02:07:10,917 --> 02:07:13,250 PROFESSOR 6: So that partly answered one of my question. 2579 02:07:13,250 --> 02:07:13,750 I had two. 2580 02:07:13,750 --> 02:07:18,480 One, what equipment does Art use at makers space, and two, 2581 02:07:18,480 --> 02:07:22,330 has he adapted or hacked any of his existing?

2700 02:12:36,280 --> 02:12:39,000 One thing that's really hard about some of these things, 2701 02:12:39,000 --> 02:12:40,630 except for the phone call, of course, 2702 02:12:40,630 --> 02:12:43,129 is that he doesn't know what's going on inside the building. 2703 02:12:43,129 --> 02:12:47,810 He can't see that on a virtual application. 2704 02:12:47,810 --> 02:12:51,550 So we've decided he needs this in everywhere that he goes, 2705 02:12:51,550 --> 02:12:53,490 but we've decided for the scope of the class 2706 02:12:53,490 --> 02:12:56,870 to focus on his school and Boston College. 2707 02:12:56,870 --> 02:12:58,860 Particularly, we're starting with the building 2708 02:12:58,860 --> 02:13:01,550 that he uses every day, which is Fulton Hall. 2709 02:13:01,550 --> 02:13:04,550 One thing about Boston College is that it's very hilly. 2710 02:13:04,550 --> 02:13:07,400 So for Chris, that's really difficult. Some of the paths 2711 02:13:07,400 --> 02:13:10,810 are sort of ramps up the hills, but they're very steep, 2712 02:13:10,810 --> 02:13:13,760 which can be difficult for his chair and also scary. 2713 02:13:13,760 --> 02:13:16,816 If he's going down, he might not be able to stop. 2714 02:13:16,816 --> 02:13:18,940 And there's a lot of stairs on some of these paths. 2715 02:13:18,940 --> 02:13:21,480 So actually he needs to go through buildings sometimes 2716 02:13:21,480 --> 02:13:23,380 and use elevators within the buildings 2717 02:13:23,380 --> 02:13:25,000 to get from a lower level of campus 2718 02:13:25,000 --> 02:13:27,190 to a higher level or vice versa. 2719 02:13:27,190 --> 02:13:28,930 And then he's a very busy students. 2720 02:13:28,930 --> 02:13:31,560 So if he needs a route like that that's not easy 2721 02:13:31,560 --> 02:13:33,620 for him to see online, he might take a long time 2722 02:13:33,620 --> 02:13:35,940 to get to his meetings or his classes, 2723 02:13:35,940 --> 02:13:37,530 and that's a problem for him. 2724 02:13:37,530 --> 02:13:40,130 And the other thing is students on campus don't really 2725 02:13:40,130 --> 02:13:42,790 know these routes, and they're also very busy, 2726 02:13:42,790 --> 02:13:45,490 so it's hard for them to help him out sometimes. 2727 02:13:45,490 --> 02:13:47,550 So our goal is to take the things 2728 02:13:47,550 --> 02:13:52,440 that he uses right now-- Google, Yelp, knowing about stairs, 2729 02:13:52,440 --> 02:13:54,270 and just going out trial and error, 2730 02:13:54,270 --> 02:13:57,470 and finding these warnings by himself-- we're 2731 02:13:57,470 --> 02:14:00,380 trying to take that uncertainty and bring all of these elements 2732 02:14:00,380 --> 02:14:02,420 together into a central application 2733 02:14:02,420 --> 02:14:05,140 that he can just go to this one place, see a map, 2734 02:14:05,140 --> 02:14:07,300 and also go inside buildings and find out 2735 02:14:07,300 --> 02:14:10,710 what things might be difficult. If an elevator isn't working. 2736 02:14:10,710 --> 02:14:12,810 If an automatic door isn't working, 2737 02:14:12,810 --> 02:14:15,420 if there happens to be something in the middle of the hallway 2738 02:14:15,420 --> 02:14:18,950 that could be in his way, or a classroom that has stairs up 2739 02:14:18,950 --> 02:14:21,480 to the seats, so he knows about these things in advance 2740 02:14:21,480 --> 02:14:22,919 and doesn't have to deal with that uncertainty 2741 02:14:22,919 --> 02:14:24,127 that he deals with every day. 2742 02:14:27,626 --> 02:14:29,460 DIRK: So Chris came into this project having 2743 02:14:29,460 --> 02:14:31,542 a pretty good idea of what he wanted us to create, 2744 02:14:31,542 --> 02:14:33,370 and that is an application that presents 2745 02:14:33,370 --> 02:14:37,520 him all of this information in an easily accessible form. 2746 02:14:37,520 --> 02:14:42,010 So our first goal was we needed to narrow down the scope, which 2747 02:14:42,010 --> 02:14:43,890 we decided was Boston College. 2748 02:14:43,890 --> 02:14:45,900 And even more than that, we decided 2749 02:14:45,900 --> 02:14:48,610 to look at three different tiers of information. 2750 02:14:48,610 --> 02:14:52,347 So the first one being at the building level. 2751 02:14:52,347 --> 02:14:53,930 So this would entail essentially being 2752 02:14:53,930 --> 02:14:55,860 able to see the entrances and exits that 2753 02:14:55,860 --> 02:14:57,920 are accessible to buildings, being 2754 02:14:57,920 --> 02:15:03,750 able to see information that is things like potholes or places 2755 02:15:03,750 --> 02:15:07,000 like hills that are hard to access outside of the building. 2756 02:15:07,000 --> 02:15:10,110 The second tier is that of the floor level, 2757 02:15:10,110 --> 02:15:12,360 actually being able to look into the buildings 2758 02:15:12,360 --> 02:15:16,190 and seeing where the locations of elevators 2759 02:15:16,190 --> 02:15:19,650 are, if there's stairs to get places, 2760 02:15:19,650 --> 02:15:22,660 where the accessible bathrooms are located. 2761 02:15:22,660 --> 02:15:26,725 And then the third tier is that of rooms, in particular, 2762 02:15:26,725 --> 02:15:28,350 if there are difficult doors to get in, 2763 02:15:28,350 --> 02:15:30,800 if it's like a lecture hall where the accessible 2764 02:15:30,800 --> 02:15:33,660 seating is, which entrances he can use, 2765 02:15:33,660 --> 02:15:37,700 and being able to present all of that in a tiered format. 2766 02:15:37,700 --> 02:15:40,030 So for our goals, we want to definitely 2767 02:15:40,030 --> 02:15:43,250 be able to do the first and the second level. 2768 02:15:43,250 --> 02:15:44,660 We think those are both feasible. 2769 02:15:44,660 --> 02:15:49,350 We're hoping to get to the third tier as well. 2770 02:15:49,350 --> 02:15:52,310 Beyond that, there are two different aspects 2771 02:15:52,310 --> 02:15:55,570 the application, that being the front end and the back end. 2772 02:15:55,570 --> 02:15:57,690 The front end is the visual display, what 2773 02:15:57,690 --> 02:15:59,740 Chris will actually be using. 2774 02:15:59,740 --> 02:16:04,050 And the back end is where this data that is being 2775 02:16:04,050 --> 02:16:06,350 displayed actually comes from. 2776 02:16:06,350 --> 02:16:08,230 Now, the interesting aspect of this project 2777 02:16:08,230 --> 02:16:12,120 is that because it is navigation-based, 2778 02:16:12,120 --> 02:16:15,180 it's based on buildings and wherever Chris wants to go, 2779 02:16:15,180 --> 02:16:20,930 ultimately his vision is to have this available for everywhere 2780 02:16:20,930 --> 02:16:22,120 he wants to go. 2781 02:16:22,120 --> 02:16:24,836 Obviously, that's not all feasible for the scope 2782 02:16:24,836 --> 02:16:26,090 of this project. 2783 02:16:26,090 --> 02:16:28,790 But we really want to have some sort of method built 2784 02:16:28,790 --> 02:16:33,510 in that allows us to expand to future locations 2785 02:16:33,510 --> 02:16:35,780 and be able to bring in different locations 2786 02:16:35,780 --> 02:16:37,910 to this application. 2787 02:16:37,910 --> 02:16:42,510 So we want to, alongside the front end on display, 2788 02:16:42,510 --> 02:16:44,770 have some sort of method for bringing 2789 02:16:44,770 --> 02:16:48,430 in new places and new data into the application. 2790 02:16:51,350 --> 02:16:53,650 As far as our actual prototypes go, 2791 02:16:53,650 --> 02:16:58,000 we initially started by all four of us creating drawings 2792 02:16:58,000 --> 02:17:01,500 explaining how sort of we saw this application coming 2793 02:17:01,500 --> 02:17:04,420 together, and we presented all of these to Chris 2794 02:17:04,420 --> 02:17:08,496 and discussed with him what he liked about each of them, 2795 02:17:08,496 --> 02:17:11,760 and took the best aspects of each, 2796 02:17:11,760 --> 02:17:16,840 and condensed them down into a singular paper prototype. 2797 02:17:16,840 --> 02:17:22,290 So initially, he liked the map view 2798 02:17:22,290 --> 02:17:24,440 that showed each of the buildings 2799 02:17:24,440 --> 02:17:27,950 with alerts for where the entrances are 2800 02:17:27,950 --> 02:17:31,219 and then being able to have things pop up, 2801 02:17:31,219 --> 02:17:34,040 such as potholes, things outside actually 2802 02:17:34,040 --> 02:17:37,730 getting to the building the he might need to be aware of. 2803 02:17:37,730 --> 02:17:39,860 Then, when he actually clicked on the building, 2804 02:17:39,860 --> 02:17:45,340 it would show up a actual floor plan, 2805 02:17:45,340 --> 02:17:48,620 being able to look at different floors within the building. 2806 02:17:48,620 --> 02:17:53,000 He liked the floor plan because it was very easy to navigate. 2807 02:17:53,000 --> 02:17:57,360 And on top of that, having different notifications, 2808 02:17:57,360 --> 02:17:59,629 different alerts, potentially color-coded 2809 02:17:59,629 --> 02:18:02,629 that show different pieces of information, 2810 02:18:02,629 --> 02:18:07,930 being where there are doors, stairs, elevators, bathrooms, 2811 02:18:07,930 --> 02:18:09,740 all this information that he wanted to be 2812 02:18:09,740 --> 02:18:12,124 able to see very easily marked. 2813 02:18:12,124 --> 02:18:14,540 One of the other big things that he wanted to make sure of 2814 02:18:14,540 --> 02:18:18,930 is that we were presenting just facts about the building. 2815 02:18:18,930 --> 02:18:23,219 He wants the information to be presented in a fairly raw form 2816 02:18:23,219 --> 02:18:26,341 so he can then determine for himself this is somewhere 2817 02:18:26,341 --> 02:18:28,090 I can go, or this is somewhere I can't go. 2818 02:18:30,910 --> 02:18:32,440 As far as actually creating this, 2819 02:18:32,440 --> 02:18:39,799 we decided on a web application because it was easier for us, 2820 02:18:39,799 --> 02:18:42,206 as far as our skills coming in, and it 2821 02:18:42,206 --> 02:18:43,664 was a lot more universal. 2822 02:18:43,664 --> 02:18:46,549 He can access it from his phone, from this computer. 2823 02:18:46,549 --> 02:18:51,410 And then we want to use JavaScript Node Express as far 2824 02:18:51,410 --> 02:18:53,722 as our languages to be able to code that and Mongo 2825 02:18:53,722 --> 02:18:54,847 for our database structure. 2826 02:19:00,600 --> 02:19:02,940 The success metrics that we want to use 2827 02:19:02,940 --> 02:19:05,799 to measure this apply to the user experience 2828 02:19:05,799 --> 02:19:08,379 side of this project, to make sure that Chris is getting 2829 02:19:08,379 --> 02:19:10,080 the most benefit out of the application 2830 02:19:10,080 --> 02:19:11,309 that we're creating. 2831 02:19:11,309 --> 02:19:14,049 And so one of the metrics that we are using 2832 02:19:14,049 --> 02:19:15,680 is the number of clicks it's going 2833 02:19:15,680 --> 02:19:19,809 to take Chris to get a specific item of information 2834 02:19:19,809 --> 02:19:20,530 that he needs. 2835 02:19:20,530 --> 02:19:23,080 So, for instance, starting from the full campus map, 2836 02:19:23,080 --> 02:19:25,490 we want him to only have to click three times 2837 02:19:25,490 --> 02:19:28,230 to get a specific floor plan of a building 2838 02:19:28,230 --> 02:19:30,559 that he wants to go into for class. 2839 02:19:30,559 --> 02:19:33,270 And upon that, click only one more time 2840 02:19:33,270 --> 02:19:35,629 to look at a specific room in that building 2841 02:19:35,629 --> 02:19:38,480 or the specific elevator and to get the information 2842 02:19:38,480 --> 02:19:41,440 that you need to know for that specific facility. 2843 02:19:41,440 --> 02:19:43,250 The second metric that we are going to use 2844 02:19:43,250 --> 02:19:47,299 is how much time it takes for him to gather this information. 2845 02:19:47,299 --> 02:19:49,900 So, as we mentioned earlier, his current methods 2846 02:19:49,900 --> 02:19:52,790 are to call the restaurant he's going to, 2847 02:19:52,790 --> 02:19:55,540 call the disabilities office, look at their website, 2848 02:19:55,540 --> 02:19:57,185 and just look through Google Maps. 2849 02:19:57,185 --> 02:19:58,560 And so we want to be able to time 2850 02:19:58,560 --> 02:20:01,220 how long it takes him to get to find information 2851 02:20:01,220 --> 02:20:03,500 about a specific classroom through those ways, 2852 02:20:03,500 --> 02:20:06,110 and then make sure that it's about 60% less 2853 02:20:06,110 --> 02:20:10,400 time for him to use our website to get that same information. 2854 02:20:10,400 --> 02:20:15,800 The third metric we're using is to allow for uncertainty-- not 2855 02:20:15,800 --> 02:20:18,290 allow for uncertainty, but to reduce as much uncertainty as 2856 02:20:18,290 --> 02:20:19,210 possible. 2857 02:20:19,210 --> 02:20:22,570 And so that way within our website, 2858 02:20:22,570 --> 02:20:25,140 he's not confused when using it, and so we 2859 02:20:25,140 --> 02:20:27,690 want to count how many questions he has, 2860 02:20:27,690 --> 02:20:32,100 and have a little help menu that he can use to clarify things. 2861 02:20:32,100 --> 02:20:33,810 But also just to reduce uncertainty 2862 02:20:33,810 --> 02:20:36,190 within all of his travel procedures 2863 02:20:36,190 --> 02:20:39,220 and to allow him to answer his questions before actually 2864 02:20:39,220 --> 02:20:41,930 going out. 2865 02:20:41,930 --> 02:20:43,860 Now for our future plans of what we're 2866 02:20:43,860 --> 02:20:46,110 doing for the rest of the semester, as Dirk mentioned, 2867 02:20:46,110 --> 02:20:48,850 we're going to split this into the back end and the front end. 2868 02:20:48,850 --> 02:20:51,030 So Dirk and Caroline are going to work on 2869 02:20:51,030 --> 02:20:53,480 in the data aggregation and database set up, 2870 02:20:53,480 --> 02:20:56,680 so getting all the information that we want to display 2871 02:20:56,680 --> 02:21:00,380 and then creating a database structure that we can scope 2872 02:21:00,380 --> 02:21:03,300 later on to add more details-- different types of buildings, 2873 02:21:03,300 --> 02:21:05,580 different floors, different facilities. 2874 02:21:05,580 --> 02:21:08,150 And Phoebe and I are going to be working on the front end 2875 02:21:08,150 --> 02:21:12,550 to increase the user usability of the whole design. 2876 02:21:12,550 --> 02:21:15,660 And since Chris wants actual facts 2877 02:21:15,660 --> 02:21:17,350 that he can interpret for himself, 2878 02:21:17,350 --> 02:21:20,920 we want to have a good balance of images and text 2879 02:21:20,920 --> 02:21:23,140 and just make sure that he's able to use 2880 02:21:23,140 --> 02:21:26,360 this in a clear way. 2881 02:21:26,360 --> 02:21:30,610 The timeline for this semester is until the end of October, 2882 02:21:30,610 --> 02:21:33,410 we want to start our coding process 2883 02:21:33,410 --> 02:21:35,880 and come up with a software prototype, 2884 02:21:35,880 --> 02:21:37,870 and in the first week of November, 2885 02:21:37,870 --> 02:21:39,640 work through our software prototype, 2886 02:21:39,640 --> 02:21:42,760 and by the end of that, have something to present to Chris 2887 02:21:42,760 --> 02:21:44,750 and have him actually test it and use it 2888 02:21:44,750 --> 02:21:46,432 so that way we can revise and reiterate 2889 02:21:46,432 --> 02:21:47,390 and keep going with it. 2890 02:21:47,390 --> 02:21:49,150 And by the end of November, we want 2891 02:21:49,150 --> 02:21:52,150 to have our final version that we can continue 2892 02:21:52,150 --> 02:21:53,633 to reiterate throughout. 2893 02:21:53,633 --> 02:21:54,216 And that's it. 2894 02:21:54,216 --> 02:21:54,799 Any questions? 2895 02:22:01,252 --> 02:22:03,710 PROFESSOR 5: All right, we have four minutes for questions. 2896 02:22:03,710 --> 02:22:05,520 Have you tried to work with Boston College 2897 02:22:05,520 --> 02:22:07,982 to get the actual floor plans, like PDFs and things? 2898 02:22:07,982 --> 02:22:09,465 Do you have all that? 2899 02:22:09,465 --> 02:22:10,840 STUDENT 6: Yes, so we're actually 2900 02:22:10,840 --> 02:22:13,880 in contact with Boston College Disabilities Office right now, 2901 02:22:13,880 --> 02:22:16,900 and they are working with the head architect 2902 02:22:16,900 --> 02:22:17,970 to get the information. 2903 02:22:17,970 --> 02:22:21,250 Right now we're just working through the legal procedures 2904 02:22:21,250 --> 02:22:22,690 of which information he's actually 2905 02:22:22,690 --> 02:22:25,107 allowed to give us and so what we're allowed to display. 2906 02:22:25,107 --> 02:22:26,690 PROFESSOR 5: MIT has a whole database. 2907 02:22:26,690 --> 02:22:28,690 If you ever want MIT, I'll show you where it is. 2908 02:22:33,320 --> 02:22:35,981 AUDIENCE: How does he update it, like if a pothole is fixed. 2909 02:22:39,460 --> 02:22:43,300 DIRK: Yeah, so that's an area that we're still 2910 02:22:43,300 --> 02:22:44,650 trying to figure out. 2911 02:22:44,650 --> 02:22:46,490 We've had a couple a different ideas, 2912 02:22:46,490 --> 02:22:49,480 one being trying to crowdsource that out somehow, 2913 02:22:49,480 --> 02:22:52,880 having the ability in the app for users, 2914 02:22:52,880 --> 02:22:56,020 if they notice something, to put that in as an alert. 2915 02:22:56,020 --> 02:22:58,790 We've thought about contacting Boston College, 2916 02:22:58,790 --> 02:23:01,800 like the maintenance or the facilities office, 2917 02:23:01,800 --> 02:23:04,230 and if their staff notices things, 2918 02:23:04,230 --> 02:23:06,070 having a way to put that in. 2919 02:23:06,070 --> 02:23:08,140 So those are a couple ideas, and we're still 2920 02:23:08,140 --> 02:23:09,986 trying to figure out exactly how the best 2921 02:23:09,986 --> 02:23:10,985 way to go about that is. 2922 02:23:13,660 --> 02:23:17,890 AUDIENCE: Excuse me, we have a colleague 2923 02:23:17,890 --> 02:23:21,100 in New York City that's done, in the past, 2924 02:23:21,100 --> 02:23:24,170 maybe two or three years ago, like a Yelp for people 2925 02:23:24,170 --> 02:23:28,991 with disabilities for accessibility to buildings. 2926 02:23:28,991 --> 02:23:33,410 I'm fairly sure the site no longer as fresh 2927 02:23:33,410 --> 02:23:36,830 as it was during his NYU [? ITP ?] days, 2928 02:23:36,830 --> 02:23:39,740 but we could put you in touch with them 2929 02:23:39,740 --> 02:23:42,911 and see how they've updated or how they basically populated 2930 02:23:42,911 --> 02:23:44,464 that information. 2931 02:23:44,464 --> 02:23:45,797 DIRK: Yeah, that would be great. 2932 02:23:51,712 --> 02:23:53,230 CIMMY: Hi, we're Team Felicity. 2933 02:23:53,230 --> 02:23:54,060 I'm Cimmy. 2934 02:23:54,060 --> 02:23:54,620 This Ari. 2935 02:23:54,620 --> 02:23:59,530 This is Becca, and we're Team Felicity. 2936 02:23:59,530 --> 02:24:02,930 This is our mid-semester review. 2937 02:24:02,930 --> 02:24:05,210 Today we're going to show you our video, talk 2938 02:24:05,210 --> 02:24:07,530 about the HAAT model for Felicity, 2939 02:24:07,530 --> 02:24:10,710 our project vision, and our accomplishments so far. 2940 02:24:10,710 --> 02:24:13,320 So we'll start off by showing you our video. 2941 02:24:13,320 --> 02:24:15,440 [VIDEO PLAYBACK] 2942 02:24:15,440 --> 02:24:17,940 -Let's like together develop a prototype 2943 02:24:17,940 --> 02:24:21,890 of assistive technology that you will find useful. 2944 02:24:21,890 --> 02:24:25,400 -I have a disease called neurofibromatosis, 2945 02:24:25,400 --> 02:24:29,370 which causes tumors to build up in the brain and spine. 2946 02:24:29,370 --> 02:24:32,570 I had surgery last February in 2014 2947 02:24:32,570 --> 02:24:35,450 to remove the tumor on this side, which also took out 2948 02:24:35,450 --> 02:24:41,560 my hearing nerve completely, so now absolutely profoundly 2949 02:24:41,560 --> 02:24:43,790 deaf on each side. 2950 02:24:43,790 --> 02:24:48,775 I also have a tumor on my optic nerve behind this eye. 2951 02:24:51,720 --> 02:24:54,420 My vision, I have days where my vision is perfectly fine, 2952 02:24:54,420 --> 02:24:56,520 and I can see everything clearly. 2953 02:24:56,520 --> 02:24:59,830 Then I have other days where things are just like really 2954 02:24:59,830 --> 02:25:05,220 cloudy and I lose depth perception 2955 02:25:05,220 --> 02:25:07,850 or have trouble seeing like walk signals, 2956 02:25:07,850 --> 02:25:12,590 like seeing whether it's white or red or flashing. 2957 02:25:12,590 --> 02:25:17,460 And I had a really close call a few weeks ago over in Fenway, 2958 02:25:17,460 --> 02:25:20,230 where, because I know I'm impaired, 2959 02:25:20,230 --> 02:25:23,370 so I'm looking for the light, and I still kind of like 2960 02:25:23,370 --> 02:25:26,220 look because I just don't trust anyone. 2961 02:25:26,220 --> 02:25:31,790 But I look for the light, and then a big truck 2962 02:25:31,790 --> 02:25:33,600 comes right towards me. 2963 02:25:33,600 --> 02:25:34,770 It was terrifying. 2964 02:25:34,770 --> 02:25:37,950 I pretty much rely on like reading people's lips, 2965 02:25:37,950 --> 02:25:39,570 and then I'll take out pen and paper 2966 02:25:39,570 --> 02:25:42,390 if it's like something that's really, really important 2967 02:25:42,390 --> 02:25:46,280 or if I'm just particularly tired 2968 02:25:46,280 --> 02:25:48,130 and don't have the energy. 2969 02:25:51,335 --> 02:25:53,600 I'm moving to a new apartment on October 1st, 2970 02:25:53,600 --> 02:25:58,290 and they're installing flashing smoke detectors, CO detector, 2971 02:25:58,290 --> 02:25:59,170 and a doorbell. 2972 02:25:59,170 --> 02:26:01,949 I've never used a flashing doorbell before, 2973 02:26:01,949 --> 02:26:02,990 so that will be exciting. 2974 02:26:06,265 --> 02:26:07,140 I can feel the vibes. 2975 02:26:16,618 --> 02:26:19,000 And I have like a computer that I watch 2976 02:26:19,000 --> 02:26:20,440 captioned DVDs on sometimes. 2977 02:26:20,440 --> 02:26:23,495 I don't have a TV or radio. 2978 02:26:28,530 --> 02:26:34,640 I set my phone to vibrate all the time for when I get emails 2979 02:26:34,640 --> 02:26:36,170 and so forth. 2980 02:26:36,170 --> 02:26:41,626 If I call you, then they'll be a relay operator. 2981 02:26:41,626 --> 02:26:42,328 -I'm doing fine. 2982 02:26:42,328 --> 02:26:43,078 Thanks for asking. 2983 02:26:43,078 --> 02:26:43,578 Go ahead. 2984 02:26:51,810 --> 02:26:53,020 -Hi, I'm Ari. 2985 02:26:53,020 --> 02:26:54,210 Hi, I'm Cimmy. 2986 02:26:54,210 --> 02:26:56,565 Hey, I'm Becca, and we're Team Felicity. 2987 02:26:56,565 --> 02:26:59,330 We've gotten to know Felicity a lot better through our meetings 2988 02:26:59,330 --> 02:27:01,159 and have come up with a lot of neat ideas. 2989 02:27:01,159 --> 02:27:02,284 We're excited to get going. 2990 02:27:07,980 --> 02:27:11,370 [END PLAYBACK] 2991 02:27:11,370 --> 02:27:13,515 CIMMY: So, as you can see, Felicity 2992 02:27:13,515 --> 02:27:17,480 has neurofibromatosis, which is a genetic disorder that 2993 02:27:17,480 --> 02:27:20,530 can causes tumors to grow on nerve tissue. 2994 02:27:20,530 --> 02:27:24,340 She had a few surgeries to take away some tumors, 2995 02:27:24,340 --> 02:27:29,220 and due to those surgeries, she lost a lot of her vision. 2996 02:27:29,220 --> 02:27:30,880 She can use her peripherals, and she's 2997 02:27:30,880 --> 02:27:32,465 profoundly deaf on both sides. 2998 02:27:36,400 --> 02:27:38,510 The activities that Felicity likes to do 2999 02:27:38,510 --> 02:27:42,270 are she really enjoys walking around Boston. 3000 02:27:42,270 --> 02:27:46,400 She also actually has routine doctor's appointments, 3001 02:27:46,400 --> 02:27:51,340 so she's usually between our home and the hospital. 3002 02:27:51,340 --> 02:27:55,220 And in terms of context, Felicity 3003 02:27:55,220 --> 02:27:57,520 lives alone at her apartment. 3004 02:27:57,520 --> 02:28:01,350 She is unemployed and frequents doctors 3005 02:28:01,350 --> 02:28:03,170 offices and the hospital. 3006 02:28:03,170 --> 02:28:06,240 And she leaves the house minimally during evening. 3007 02:28:06,240 --> 02:28:08,160 She doesn't like to be out at night. 3008 02:28:08,160 --> 02:28:11,520 And she happens to be very open to letting 3009 02:28:11,520 --> 02:28:14,540 people know that she is deaf and using 3010 02:28:14,540 --> 02:28:17,520 assistive technology between that. 3011 02:28:20,250 --> 02:28:22,770 In terms of assistive technology that Felicity already 3012 02:28:22,770 --> 02:28:26,100 uses, so to communicate with her, 3013 02:28:26,100 --> 02:28:31,380 we have been using a notepad or a laptop with size 36 font 3014 02:28:31,380 --> 02:28:33,510 so she can read it. 3015 02:28:33,510 --> 02:28:37,890 And she also uses her iPhone, as you saw on the video. 3016 02:28:37,890 --> 02:28:39,590 She receives emails from her doctor 3017 02:28:39,590 --> 02:28:42,080 when she's out the doctor's office to notify her 3018 02:28:42,080 --> 02:28:45,550 when they're ready for her. 3019 02:28:45,550 --> 02:28:49,620 And she uses a Sprint relay app for phone calls and so on. 3020 02:28:49,620 --> 02:28:52,850 And, as you saw on the video, a flashing smoke detector, 3021 02:28:52,850 --> 02:28:55,300 and a CO alarm are installed in her home, 3022 02:28:55,300 --> 02:29:02,070 and she also has a flashing doorbell, which the noise is 3023 02:29:02,070 --> 02:29:05,430 loud enough that she actually feel the vibrations when 3024 02:29:05,430 --> 02:29:08,160 they're occurring. 3025 02:29:08,160 --> 02:29:12,200 So now I'll switch over to Becca. 3026 02:29:12,200 --> 02:29:14,080 BECCA: So I guess along the way of getting 3027 02:29:14,080 --> 02:29:16,420 to know Felicity and her daily life, 3028 02:29:16,420 --> 02:29:18,530 we like discussed a lot of activities 3029 02:29:18,530 --> 02:29:22,670 that we could potentially help her design an AT solution for. 3030 02:29:22,670 --> 02:29:25,340 We had to kind of whittle it down to one motivation 3031 02:29:25,340 --> 02:29:27,702 that we could center a project around. 3032 02:29:27,702 --> 02:29:29,660 And so the problem that we're going to focus on 3033 02:29:29,660 --> 02:29:32,210 is that Felicity can't always detect when events occur 3034 02:29:32,210 --> 02:29:34,190 because she's mostly deaf. 3035 02:29:34,190 --> 02:29:36,340 And so these include like if people call her name, 3036 02:29:36,340 --> 02:29:40,000 either at a cafe or at the doctor's office, 3037 02:29:40,000 --> 02:29:42,890 or if a laundry machine's done, or when 3038 02:29:42,890 --> 02:29:44,920 she's going on her walks, she can't hear cars 3039 02:29:44,920 --> 02:29:47,319 honking from incoming traffic. 3040 02:29:47,319 --> 02:29:48,860 And so these are all situations where 3041 02:29:48,860 --> 02:29:50,624 somehow RET could help her. 3042 02:29:50,624 --> 02:29:52,040 And so our goal for the project is 3043 02:29:52,040 --> 02:29:54,930 to develop an AT that will notify Felicity 3044 02:29:54,930 --> 02:29:58,280 when particular events happen. 3045 02:29:58,280 --> 02:30:01,130 So this is variation came particularly from an email 3046 02:30:01,130 --> 02:30:04,845 that Felicity sent to us with this hearing dogs video in it. 3047 02:30:04,845 --> 02:30:06,720 I guess we don't have time to show the video, 3048 02:30:06,720 --> 02:30:10,619 but the idea was just that she saw this hearing dog video, 3049 02:30:10,619 --> 02:30:12,160 and at the end of her email she said, 3050 02:30:12,160 --> 02:30:13,785 it would be really cool if I could have 3051 02:30:13,785 --> 02:30:15,740 my own handheld hearing dog. 3052 02:30:15,740 --> 02:30:19,460 And so that was a cool step towards, for us, 3053 02:30:19,460 --> 02:30:22,450 to find a solution for her. 3054 02:30:22,450 --> 02:30:24,720 And so throughout so far, we've currently 3055 02:30:24,720 --> 02:30:27,140 been going through an iterative design process 3056 02:30:27,140 --> 02:30:29,210 to kind of whittle go down a solution 3057 02:30:29,210 --> 02:30:31,100 and find something that works for her. 3058 02:30:31,100 --> 02:30:32,790 We've been using low fidelity prototypes 3059 02:30:32,790 --> 02:30:35,640 to get feedback from Felicity, even to narrow down 3060 02:30:35,640 --> 02:30:37,120 for our project solution. 3061 02:30:37,120 --> 02:30:40,410 And as we'll talk about a little later, 3062 02:30:40,410 --> 02:30:42,580 our initial design process showed us 3063 02:30:42,580 --> 02:30:46,214 that our project problem changed after discussions with her. 3064 02:30:46,214 --> 02:30:48,380 So this is just some example of some of the sketches 3065 02:30:48,380 --> 02:30:49,360 we've done. 3066 02:30:49,360 --> 02:30:53,210 In this example, we had two parts of a solution. 3067 02:30:53,210 --> 02:30:56,135 One was a button that someone could pass for her attention, 3068 02:30:56,135 --> 02:30:58,260 and the other would be some sort of wearable device 3069 02:30:58,260 --> 02:31:01,580 that would vibrate, telling her once like this button has 3070 02:31:01,580 --> 02:31:02,159 been pushed. 3071 02:31:02,159 --> 02:31:03,950 Now Ari is going to share a little bit more 3072 02:31:03,950 --> 02:31:06,325 about our initial problem statement and problem overview. 3073 02:31:11,740 --> 02:31:15,140 ARI: Right, so the first project we wanted to tackle 3074 02:31:15,140 --> 02:31:19,270 was trying to let Felicity know when someone called out 3075 02:31:19,270 --> 02:31:20,410 her name. 3076 02:31:20,410 --> 02:31:23,880 And because she can't hear and she has limited vision, 3077 02:31:23,880 --> 02:31:28,100 it's pretty difficult if she was in like a waiting 3078 02:31:28,100 --> 02:31:32,150 room or the doctor's office or in a classroom 3079 02:31:32,150 --> 02:31:35,190 to like figure out if someone's trying to contact her. 3080 02:31:35,190 --> 02:31:39,550 So the idea we came up with was rather than having someone 3081 02:31:39,550 --> 02:31:43,390 try to call out their name, we would have them have a button 3082 02:31:43,390 --> 02:31:44,970 that they could press. 3083 02:31:44,970 --> 02:31:46,950 And when they press the button, it 3084 02:31:46,950 --> 02:31:49,159 would contact Felicity that they were 3085 02:31:49,159 --> 02:31:50,325 trying to get her attention. 3086 02:31:53,170 --> 02:31:57,110 So this is the kind of overview of that design. 3087 02:31:57,110 --> 02:31:59,570 We have a button that someone could press. 3088 02:31:59,570 --> 02:32:02,410 It would send a message to her iPhone, 3089 02:32:02,410 --> 02:32:04,490 and then the iPhone would display 3090 02:32:04,490 --> 02:32:06,110 some sort of notification. 3091 02:32:06,110 --> 02:32:08,290 And then we'd also have a wearable device 3092 02:32:08,290 --> 02:32:10,837 that she could use, and they both display notifications. 3093 02:32:10,837 --> 02:32:12,295 So kind of a two-step notification. 3094 02:32:18,310 --> 02:32:21,510 Luckily, we really worked on doing iterative design 3095 02:32:21,510 --> 02:32:23,720 and also user-centered design because we 3096 02:32:23,720 --> 02:32:25,810 try talking with her about how well does 3097 02:32:25,810 --> 02:32:29,630 she think this will work, and she really liked this idea. 3098 02:32:29,630 --> 02:32:33,670 But she was concerned about other people using it. 3099 02:32:33,670 --> 02:32:36,340 And so one thing we tried talking with her 3100 02:32:36,340 --> 02:32:38,130 is what would you like more? 3101 02:32:38,130 --> 02:32:40,580 And particularly, she would want something 3102 02:32:40,580 --> 02:32:44,720 that she could use possibly more often and also independently 3103 02:32:44,720 --> 02:32:48,460 because this original project involves two clients-- Felicity 3104 02:32:48,460 --> 02:32:50,920 and whoever we give the button to. 3105 02:32:50,920 --> 02:32:52,890 And so the new focus of our project 3106 02:32:52,890 --> 02:32:56,200 changed to try and make some sort of way 3107 02:32:56,200 --> 02:32:59,030 to make sound emitting appliances within her home 3108 02:32:59,030 --> 02:33:01,643 accessible for Felicity. 3109 02:33:04,960 --> 02:33:07,510 So basically within Felicity's apartment 3110 02:33:07,510 --> 02:33:10,680 she has a few different household appliances 3111 02:33:10,680 --> 02:33:13,760 that she doesn't know when they're done working. 3112 02:33:13,760 --> 02:33:16,680 In particular, the laundry machine, when it's done, 3113 02:33:16,680 --> 02:33:19,910 it just triggers a beep, and it doesn't have a timer. 3114 02:33:19,910 --> 02:33:23,450 So she would like a way to know when it's finished. 3115 02:33:23,450 --> 02:33:26,720 And basically the idea we have is 3116 02:33:26,720 --> 02:33:28,380 we could have some sort of device 3117 02:33:28,380 --> 02:33:31,530 that she could place next to the household appliance. 3118 02:33:31,530 --> 02:33:33,740 And then when the appliance is finished 3119 02:33:33,740 --> 02:33:37,240 doing whatever its task is, it will emit some noise, 3120 02:33:37,240 --> 02:33:39,910 and this device would pick up on it 3121 02:33:39,910 --> 02:33:42,330 and send a signal to Felicity to let 3122 02:33:42,330 --> 02:33:44,900 her know that whatever the household appliance 3123 02:33:44,900 --> 02:33:48,470 task has completed. 3124 02:33:48,470 --> 02:33:52,230 So again, we kind of kept last half of the project 3125 02:33:52,230 --> 02:33:56,200 that we started scoping out and just talking about. 3126 02:33:56,200 --> 02:33:58,170 And instead, now we have a microphone 3127 02:33:58,170 --> 02:34:00,920 that would be placed next to the household appliance, 3128 02:34:00,920 --> 02:34:06,310 and then the microphone would be sending sound to the iPhone. 3129 02:34:06,310 --> 02:34:08,510 And within the iPhone we could have an application 3130 02:34:08,510 --> 02:34:15,390 that would notify when the sound of the appliance finishing 3131 02:34:15,390 --> 02:34:17,030 has happened. 3132 02:34:17,030 --> 02:34:23,000 So for the implementation we decide 3133 02:34:23,000 --> 02:34:26,930 to use Bluetooth because this is in her apartment. 3134 02:34:26,930 --> 02:34:30,190 It's less than 30 feet, and also Felicity 3135 02:34:30,190 --> 02:34:33,140 leaves her phone plugged in while she's at her house. 3136 02:34:33,140 --> 02:34:36,890 So we're not too worried about that part. 3137 02:34:36,890 --> 02:34:40,600 And then right now we're all working on developing an iPhone 3138 02:34:40,600 --> 02:34:42,916 application for detecting the sound and also 3139 02:34:42,916 --> 02:34:43,999 the Bluetooth integration. 3140 02:34:48,730 --> 02:34:50,450 So these are kind of the hardware pieces 3141 02:34:50,450 --> 02:34:52,140 we've been also testing out. 3142 02:34:52,140 --> 02:34:55,390 The first one was a Bluetooth camera shutter button, 3143 02:34:55,390 --> 02:34:57,790 and we also have a headset that we're just 3144 02:34:57,790 --> 02:35:00,641 using as a microphone because we already have it, 3145 02:35:00,641 --> 02:35:02,682 and we're just trying to do low-cost prototyping. 3146 02:35:08,067 --> 02:35:10,400 BECCA: So to talk a little bit about the success metrics 3147 02:35:10,400 --> 02:35:13,590 that we set up for our project, for the technical side, 3148 02:35:13,590 --> 02:35:15,736 we broke down our project in two parts. 3149 02:35:15,736 --> 02:35:18,110 There's going to be a noise detection to the iPhone part, 3150 02:35:18,110 --> 02:35:20,980 and then the iPhone to the notification part. 3151 02:35:20,980 --> 02:35:23,010 And so from there, we have like two activities-- 3152 02:35:23,010 --> 02:35:25,590 the amount of noise that this microphone 3153 02:35:25,590 --> 02:35:29,300 could withstand before, and also correctly detect the appliance. 3154 02:35:29,300 --> 02:35:32,370 And those are kind of our levels of how good 3155 02:35:32,370 --> 02:35:34,530 it would be, where level two would be ideal, 3156 02:35:34,530 --> 02:35:37,599 and level zero is not actually doing its job, and then 3157 02:35:37,599 --> 02:35:39,140 the number of noises it would detect. 3158 02:35:39,140 --> 02:35:43,587 And then for the iPhone to notification part, 3159 02:35:43,587 --> 02:35:45,420 the success metric would be like the percent 3160 02:35:45,420 --> 02:35:47,870 times the notification actually succeeds and is correctly 3161 02:35:47,870 --> 02:35:50,972 pinging Felicity. 3162 02:35:50,972 --> 02:35:52,680 And then we have for overall performance, 3163 02:35:52,680 --> 02:35:54,596 I guess the best way to measure our success is 3164 02:35:54,596 --> 02:35:57,050 just how many appliances we can actually adapt this to. 3165 02:35:57,050 --> 02:35:59,830 And so the laundry machine, dryer, toaster oven, 3166 02:35:59,830 --> 02:36:02,360 and tea pot are just five things that we 3167 02:36:02,360 --> 02:36:05,430 are kind of aiming towards being able to make this for. 3168 02:36:05,430 --> 02:36:07,705 And also we're considering maintenance as well. 3169 02:36:07,705 --> 02:36:09,080 Once we finish with this project, 3170 02:36:09,080 --> 02:36:11,150 we want to make sure that all the parts of our project 3171 02:36:11,150 --> 02:36:13,150 are replaceable so that Felicity can continue 3172 02:36:13,150 --> 02:36:15,580 to use it once we're not there. 3173 02:36:15,580 --> 02:36:20,104 From the UI perspective side, the best way quantitatively 3174 02:36:20,104 --> 02:36:21,770 to measure this is just the average time 3175 02:36:21,770 --> 02:36:24,370 it would take to set up a notification for a machine task 3176 02:36:24,370 --> 02:36:27,710 that she has, and then also her own perspective 3177 02:36:27,710 --> 02:36:29,312 about whether or not she things the UI 3178 02:36:29,312 --> 02:36:30,520 is intuitive and easy to use. 3179 02:36:35,750 --> 02:36:38,240 CIMMY: And in terms of our project development so far, 3180 02:36:38,240 --> 02:36:42,280 we have purchased at Bluetooth camera shutter remote button, 3181 02:36:42,280 --> 02:36:48,310 which was actually for our previous idea, 3182 02:36:48,310 --> 02:36:52,760 in order for Felicity to be able to give a button to someone 3183 02:36:52,760 --> 02:36:57,020 so that they could press it to a signal her phone 3184 02:36:57,020 --> 02:36:59,890 that she's getting a signal. 3185 02:36:59,890 --> 02:37:03,160 And we started developing an iPhone application 3186 02:37:03,160 --> 02:37:05,780 for the project that we've moved towards, 3187 02:37:05,780 --> 02:37:09,090 and now we're investigating wearable devices that Felicity 3188 02:37:09,090 --> 02:37:12,000 could wear for notification. 3189 02:37:12,000 --> 02:37:14,020 And we're leaning more towards the side 3190 02:37:14,020 --> 02:37:17,690 of some sort of wrist wearable or something 3191 02:37:17,690 --> 02:37:20,020 that she could hold. 3192 02:37:20,020 --> 02:37:22,790 And in terms of our project's plans and timelines, 3193 02:37:22,790 --> 02:37:25,550 this is just a general timeline that we have. 3194 02:37:25,550 --> 02:37:30,810 We hope to get her iPhone app working at a low scale 3195 02:37:30,810 --> 02:37:33,200 so that we can just have her iPhone connected 3196 02:37:33,200 --> 02:37:36,000 with some microphone and see how well that works, if we're 3197 02:37:36,000 --> 02:37:39,320 getting a vibration notification, 3198 02:37:39,320 --> 02:37:42,770 gather appliances and a sound library by November 7th, 3199 02:37:42,770 --> 02:37:44,270 and then test the app functionality. 3200 02:37:44,270 --> 02:37:49,500 We want to focus a lot on having Felicity test out the app 3201 02:37:49,500 --> 02:37:51,980 and see how well it works. 3202 02:37:51,980 --> 02:37:57,250 And then probably by the 28th of November, 3203 02:37:57,250 --> 02:38:02,500 we want to clean up the final project and work on the UI 3204 02:38:02,500 --> 02:38:05,450 and fix bugs on the last week. 3205 02:38:09,432 --> 02:38:09,932 Thank you. 3206 02:38:12,416 --> 02:38:13,916 PROFESSOR 4: Questions and comments? 3207 02:38:21,087 --> 02:38:23,378 AUDIENCE: So for the appliances you were talking about, 3208 02:38:23,378 --> 02:38:29,305 like tea pot, laundry, and [INAUDIBLE], 3209 02:38:29,305 --> 02:38:31,346 would it make more sense to use a timer for that? 3210 02:38:31,346 --> 02:38:34,334 Because each of those appliances are pretty set 3211 02:38:34,334 --> 02:38:37,977 timings for the [INAUDIBLE]. 3212 02:38:37,977 --> 02:38:40,310 Would that be easier than detecting a sound [INAUDIBLE]? 3213 02:38:43,796 --> 02:38:46,226 BECCA: So that's something that we asked Felicity about, 3214 02:38:46,226 --> 02:38:47,350 and I think she-- oh sorry. 3215 02:38:47,350 --> 02:38:48,950 That is something we asked, we brought up 3216 02:38:48,950 --> 02:38:50,991 when we were talking about this is with Felicity. 3217 02:38:50,991 --> 02:38:54,100 But, I think, one thing is like you don't always 3218 02:38:54,100 --> 02:38:56,610 remember to set up the timer, or sometimes 3219 02:38:56,610 --> 02:38:59,042 you just like run into something else that you do. 3220 02:38:59,042 --> 02:39:01,250 And so you told yourself, oh, I was going to do that. 3221 02:39:01,250 --> 02:39:03,159 But she just forgets. 3222 02:39:03,159 --> 02:39:05,700 And also when she's home, she doesn't keep her iPhone on her. 3223 02:39:05,700 --> 02:39:07,940 So she usually has it plugged in, 3224 02:39:07,940 --> 02:39:12,260 so if she can't hear the alarm, or even if it was vibrating, 3225 02:39:12,260 --> 02:39:14,335 she just doesn't know if she's in another room 3226 02:39:14,335 --> 02:39:17,409 or she's taking a nap to actually go and check on it. 3227 02:39:17,409 --> 02:39:19,492 So I think when we did introduce this idea to her, 3228 02:39:19,492 --> 02:39:21,890 and we told her, well, there are like other alternatives that 3229 02:39:21,890 --> 02:39:23,390 seem more feasible, she really liked 3230 02:39:23,390 --> 02:39:25,621 the idea of having something that's preferably 3231 02:39:25,621 --> 02:39:26,870 a wearable that just vibrates. 3232 02:39:26,870 --> 02:39:28,890 Then she doesn't have to be thinking about it. 3233 02:39:28,890 --> 02:39:30,580 But she'll know exactly when it's ringing that she 3234 02:39:30,580 --> 02:39:31,663 should go back and see it. 3235 02:39:33,900 --> 02:39:35,400 AUDIENCE: Why do you need the phone? 3236 02:39:38,067 --> 02:39:40,400 BECCA: So I think first in terms of like implementation, 3237 02:39:40,400 --> 02:39:43,190 it's a bit easier to have an iPhone 3238 02:39:43,190 --> 02:39:47,800 app be the one that's sending the Bluetooth signal back 3239 02:39:47,800 --> 02:39:48,830 to the wearable. 3240 02:39:48,830 --> 02:39:51,940 And also in terms of modularity, I think, 3241 02:39:51,940 --> 02:39:54,610 it would be a more complicated hardware solution 3242 02:39:54,610 --> 02:39:57,190 if it was intelligently picking up just 3243 02:39:57,190 --> 02:40:00,045 to send to the specific hardware device. 3244 02:40:00,045 --> 02:40:07,160 I'm sorry, from like sound detector to the wearable, 3245 02:40:07,160 --> 02:40:09,530 it's two more complicated hardware solutions. 3246 02:40:09,530 --> 02:40:12,570 And so then it's the question of maintenance, 3247 02:40:12,570 --> 02:40:14,750 like how is she going to replace these more 3248 02:40:14,750 --> 02:40:15,960 complicated solutions? 3249 02:40:15,960 --> 02:40:17,949 But instead, we're using two kind 3250 02:40:17,949 --> 02:40:20,490 of just all they have to do is either send a Bluetooth signal 3251 02:40:20,490 --> 02:40:22,350 and then receive a Bluetooth signal, 3252 02:40:22,350 --> 02:40:25,460 and that's like two much cheaper hardware pieces for us to get. 3253 02:40:25,460 --> 02:40:27,141 And she could always replace those. 3254 02:40:27,141 --> 02:40:28,640 And then the iPhone app is something 3255 02:40:28,640 --> 02:40:29,940 that she'd already have. 3256 02:40:29,940 --> 02:40:31,950 AUDIENCE: How much is a Bluetooth switch? 3257 02:40:31,950 --> 02:40:33,790 BECCA: Yeah, so what we looked at so far, 3258 02:40:33,790 --> 02:40:36,810 like out-of-the0box solutions to be like $30 to $40. 3259 02:40:41,076 --> 02:40:42,492 AUDIENCE: If you skip the phone, I 3260 02:40:42,492 --> 02:40:48,110 guess, you would be able to use an RF link for $5? 3261 02:40:48,110 --> 02:40:51,010 BECCA: OK, but would that be able to know-- 3262 02:40:51,010 --> 02:40:53,030 like would the notification collector, 3263 02:40:53,030 --> 02:40:56,140 I mean the sound detector, know to send it exactly 3264 02:40:56,140 --> 02:41:01,535 to this Bluetooth wearable? 3265 02:41:01,535 --> 02:41:04,191 Or is that a Bluetooth [INAUDIBLE] RF? 3266 02:41:04,191 --> 02:41:06,190 ARI: I guess one thing we'd also like to include 3267 02:41:06,190 --> 02:41:09,770 is one of the reasons we kind of stuck with iPhone 3268 02:41:09,770 --> 02:41:13,350 is we were interested in finding commercial products that we 3269 02:41:13,350 --> 02:41:16,968 don't have to customize any of the hardware, 3270 02:41:16,968 --> 02:41:18,384 especially with the button design. 3271 02:41:18,384 --> 02:41:21,510 If it broke, she could easily purchase a new one. 3272 02:41:21,510 --> 02:41:25,110 Like those buttons that we first shows, they're under $10 3273 02:41:25,110 --> 02:41:26,910 to get similar designs. 3274 02:41:26,910 --> 02:41:28,705 So what we're really hoping to get 3275 02:41:28,705 --> 02:41:31,515 is something that will work after we're 3276 02:41:31,515 --> 02:41:33,580 done with the class. 3277 02:41:33,580 --> 02:41:35,260 So you can purchase these designs 3278 02:41:35,260 --> 02:41:38,390 and keep making designs that work with the iPhone, then 3279 02:41:38,390 --> 02:41:39,760 why don't we capitalize on that? 3280 02:41:42,533 --> 02:41:44,574 PROFESSOR 4: So, Leonard, do you have a question? 3281 02:41:49,286 --> 02:41:51,160 PROFESSOR 5: Did you make an actual prototype 3282 02:41:51,160 --> 02:41:52,825 for-- what was your prototype? 3283 02:41:56,702 --> 02:41:58,660 BECCA: It was mostly so far just like sketches. 3284 02:41:58,660 --> 02:42:00,296 It was mostly sketches to show her 3285 02:42:00,296 --> 02:42:02,265 like, OK, these are three pieces, two pieces, 3286 02:42:02,265 --> 02:42:04,275 or like, these are kinds of pieces we're talking about, 3287 02:42:04,275 --> 02:42:06,441 and then like whether or not you even like the idea. 3288 02:42:06,441 --> 02:42:08,350 PROFESSOR 5: Sort of like a storyboard? 3289 02:42:08,350 --> 02:42:09,766 BECCA: Yeah, and user [? flows. ?] 3290 02:42:12,060 --> 02:42:15,434 ARI: And we also brought the physical hardware 3291 02:42:15,434 --> 02:42:18,226 of that button to kind of see how she liked it, would 3292 02:42:18,226 --> 02:42:20,067 she feel like it's OK to use. 3293 02:42:20,067 --> 02:42:22,150 PROFESSOR 5: So you're going to run with that one? 3294 02:42:22,150 --> 02:42:24,191 The you bought, is that what you're going to use, 3295 02:42:24,191 --> 02:42:26,020 or are you going to use something else? 3296 02:42:26,020 --> 02:42:27,520 ARI: No, we're planning on switching 3297 02:42:27,520 --> 02:42:29,650 to try to make something that only works 3298 02:42:29,650 --> 02:42:32,400 with her independently because we're concerned about having 3299 02:42:32,400 --> 02:42:34,830 the extra client that couldn't really control, 3300 02:42:34,830 --> 02:42:36,900 make sure they were on board. 3301 02:42:36,900 --> 02:42:38,900 BECCA: So it's like microphone, iPhone, and then 3302 02:42:38,900 --> 02:42:41,375 wearable or something to like [INAUDIBLE]. 3303 02:42:43,725 --> 02:42:45,350 PROFESSOR 5: OK, I think we're at time. 3304 02:42:45,350 --> 02:42:46,370 Thank you very much. 3305 02:42:53,950 --> 02:42:56,370 EANN: Hi, we're Team Don, and my name is Eann. 3306 02:42:56,370 --> 02:42:58,814 This is Christina, and over here is Jan. 3307 02:42:58,814 --> 02:43:00,730 First, we'd like to tell you a little bit more 3308 02:43:00,730 --> 02:43:01,820 about our client. 3309 02:43:01,820 --> 02:43:05,180 Our client's name is Don, and he is a male senior citizen 3310 02:43:05,180 --> 02:43:06,320 who currently lives alone. 3311 02:43:06,320 --> 02:43:09,080 He's a strong advocate for support groups, 3312 02:43:09,080 --> 02:43:12,610 and he constantly tells us about how he goes to conferences 3313 02:43:12,610 --> 02:43:15,870 and speaks to health professionals. 3314 02:43:15,870 --> 02:43:19,260 And he suffered from polio during his childhood, 3315 02:43:19,260 --> 02:43:21,340 and that is affected his left leg. 3316 02:43:21,340 --> 02:43:25,420 But in 2002, he also suffer from a stroke 3317 02:43:25,420 --> 02:43:27,800 that affected the right hemisphere of his brain. 3318 02:43:27,800 --> 02:43:31,300 So currently he has limited use of his left side and especially 3319 02:43:31,300 --> 02:43:34,510 his left arm, and this has also resulted 3320 02:43:34,510 --> 02:43:37,010 in cognitive difficulties, especially 3321 02:43:37,010 --> 02:43:39,336 in the late afternoon or early afternoon, 3322 02:43:39,336 --> 02:43:41,460 whenever sometimes it's a little bit harder for him 3323 02:43:41,460 --> 02:43:45,340 to process and to focus and to just kind of stay 3324 02:43:45,340 --> 02:43:47,390 on track with whatever conversation 3325 02:43:47,390 --> 02:43:48,700 he's currently engaged in. 3326 02:43:51,280 --> 02:43:54,450 From our very first meeting, we knew that Don loved food, 3327 02:43:54,450 --> 02:43:55,650 and he loved to cook. 3328 02:43:55,650 --> 02:43:57,100 So one of our very first questions 3329 02:43:57,100 --> 02:43:59,600 was, what's your favorite flavor of ice cream? 3330 02:43:59,600 --> 02:44:03,210 And this kind of transcended into this conversation of food, 3331 02:44:03,210 --> 02:44:05,400 and we discovered that Don was actually 3332 02:44:05,400 --> 02:44:09,790 a food catering manager prior to his disability. 3333 02:44:09,790 --> 02:44:13,050 And when you first started at his job at KFC, 3334 02:44:13,050 --> 02:44:16,690 he learned about his passion for cooking and expressing himself 3335 02:44:16,690 --> 02:44:17,710 through food. 3336 02:44:17,710 --> 02:44:20,140 And so as a result, he still cooks, 3337 02:44:20,140 --> 02:44:22,737 and he constantly talks about different recipes. 3338 02:44:22,737 --> 02:44:24,570 And we got the opportunity to make omelettes 3339 02:44:24,570 --> 02:44:25,740 with him one day. 3340 02:44:25,740 --> 02:44:28,890 And so with his left hand, it typically is stable, 3341 02:44:28,890 --> 02:44:31,050 and he uses his right hand to cook. 3342 02:44:31,050 --> 02:44:33,150 And with his left hand held typically either 3343 02:44:33,150 --> 02:44:35,710 brace apart or hold onto a cheese package, 3344 02:44:35,710 --> 02:44:37,030 and rip open the top. 3345 02:44:37,030 --> 02:44:39,340 But typically, it's only just his right arm 3346 02:44:39,340 --> 02:44:42,175 that he uses, and it's essentially 3347 02:44:42,175 --> 02:44:47,560 his only method of cooking-- or only manner of cooking. 3348 02:44:47,560 --> 02:44:52,250 And so this you can see is in his actual apartment. 3349 02:44:52,250 --> 02:44:55,670 We got the opportunity to go visit Don in his apartment 3350 02:44:55,670 --> 02:44:59,580 and kind of see where he lives and see where he actually 3351 02:44:59,580 --> 02:45:00,970 takes the time to cook. 3352 02:45:00,970 --> 02:45:02,630 And so we noticed that is apartment 3353 02:45:02,630 --> 02:45:05,420 is actually-- his kitchen is actually fairly small. 3354 02:45:05,420 --> 02:45:10,030 It is about the size of a small kitchen in Burton Conner, which 3355 02:45:10,030 --> 02:45:11,630 is a dorm on campus. 3356 02:45:11,630 --> 02:45:13,250 And you can see in the next slide 3357 02:45:13,250 --> 02:45:16,980 that the stove is fairly close to the sink, 3358 02:45:16,980 --> 02:45:24,020 and so it's a pretty small quarter for cooking. 3359 02:45:24,020 --> 02:45:26,540 And he's looking for a way to improve 3360 02:45:26,540 --> 02:45:27,945 the mobility in his kitchen. 3361 02:45:31,010 --> 02:45:33,210 The assistive technology that Don uses 3362 02:45:33,210 --> 02:45:37,310 includes Velcro, which is on the left hand side. 3363 02:45:37,310 --> 02:45:39,710 He constantly tells us that Velcro is his friend, 3364 02:45:39,710 --> 02:45:41,850 and he uses Velcro for his shoes. 3365 02:45:41,850 --> 02:45:44,300 And on the far right side, he also 3366 02:45:44,300 --> 02:45:46,490 uses a leg brace that prevents him 3367 02:45:46,490 --> 02:45:48,380 from hyperextending his knee. 3368 02:45:48,380 --> 02:45:51,330 But the most important assistive technology that he uses 3369 02:45:51,330 --> 02:45:53,120 is in the center, his iPhone. 3370 02:45:53,120 --> 02:45:55,350 So you can see, he's clearly really excited about it, 3371 02:45:55,350 --> 02:45:59,170 and he's constantly using it to schedule tasks, to send emails, 3372 02:45:59,170 --> 02:46:03,478 and he depends on this iPhone to remind him of his daily tasks. 3373 02:46:08,750 --> 02:46:12,110 So in addition to those three items, 3374 02:46:12,110 --> 02:46:14,040 he also uses a cane to help him walk. 3375 02:46:14,040 --> 02:46:17,480 And so this is a quick video of him using his cane, 3376 02:46:17,480 --> 02:46:20,430 and it's just simply to help him walk 3377 02:46:20,430 --> 02:46:22,270 and to assist him in being mobile. 3378 02:46:28,399 --> 02:46:29,940 JAN: So some challenges we've already 3379 02:46:29,940 --> 02:46:32,590 seemed to have faced in this design 3380 02:46:32,590 --> 02:46:34,820 project is our team scheduling. 3381 02:46:34,820 --> 02:46:37,260 So it's really hard for us three to get together 3382 02:46:37,260 --> 02:46:41,910 with Don at the same time, same place, and get something going. 3383 02:46:41,910 --> 02:46:44,900 And with Don's cognitive overload, 3384 02:46:44,900 --> 02:46:47,849 he also has issues focusing and telling us 3385 02:46:47,849 --> 02:46:49,890 what he really wants for us to do on our project. 3386 02:46:49,890 --> 02:46:53,070 So we initially started out with two projects 3387 02:46:53,070 --> 02:46:56,140 that we were going to work for helping him with his cooking. 3388 02:46:56,140 --> 02:46:58,700 As you can see here, we started off thinking of ways 3389 02:46:58,700 --> 02:47:00,420 that we can help him out in the kitchen. 3390 02:47:00,420 --> 02:47:02,470 So something that he did mention to us 3391 02:47:02,470 --> 02:47:06,060 was the fact that he needs some help carrying big pots. 3392 02:47:06,060 --> 02:47:08,540 So since he has one arm, it's really hard 3393 02:47:08,540 --> 02:47:12,120 to actually stabilize the pot and move it from point A 3394 02:47:12,120 --> 02:47:14,330 to point B without having the contents spill 3395 02:47:14,330 --> 02:47:16,070 and move around too much. 3396 02:47:16,070 --> 02:47:18,770 And another thing that was mentioned to us by-- oh, he's 3397 02:47:18,770 --> 02:47:21,560 not here today-- another one of the actual participants 3398 02:47:21,560 --> 02:47:24,000 of this class, Jeffrey, was something 3399 02:47:24,000 --> 02:47:26,770 used for stirring or stabilizing the pot 3400 02:47:26,770 --> 02:47:28,940 whenever he's either stirring or doing something 3401 02:47:28,940 --> 02:47:30,560 with the contents of the pot. 3402 02:47:30,560 --> 02:47:34,080 And we initially started off with two different projects 3403 02:47:34,080 --> 02:47:36,370 that we were going to test out with Don 3404 02:47:36,370 --> 02:47:39,340 and figure out what he really wanted out of us in this class. 3405 02:47:39,340 --> 02:47:42,070 So the first one was the stability of the mixing pot 3406 02:47:42,070 --> 02:47:45,120 or doing something with the pot or a bow. 3407 02:47:45,120 --> 02:47:47,790 And we decided that we wanted to focus on these three 3408 02:47:47,790 --> 02:47:50,970 little things, so minimizing how much the bowl moves, 3409 02:47:50,970 --> 02:47:55,560 how much it tips over, and making sure that whatever 3410 02:47:55,560 --> 02:47:58,830 we use is fast and easy to use. 3411 02:47:58,830 --> 02:48:00,300 And as for moving pots, we wanted 3412 02:48:00,300 --> 02:48:03,550 to focus more on how he can take these pots from point A 3413 02:48:03,550 --> 02:48:07,420 to point B, so large pots with a lot of things inside of them, 3414 02:48:07,420 --> 02:48:09,266 and minimize how much effort he has 3415 02:48:09,266 --> 02:48:11,670 to put into moving these things and stabilizing them, 3416 02:48:11,670 --> 02:48:14,530 while making it very easy to use as well 3417 02:48:14,530 --> 02:48:18,720 and minimizing how much liquid falls off 3418 02:48:18,720 --> 02:48:21,930 or how many things could go wrong with this. 3419 02:48:21,930 --> 02:48:24,390 So we initially started off with some design prototypes 3420 02:48:24,390 --> 02:48:29,575 for the stirring or for slipping is something that we called it. 3421 02:48:29,575 --> 02:48:32,500 So we started for slipping, and we showed him 3422 02:48:32,500 --> 02:48:35,450 some of these designs, and we got some very good feedback 3423 02:48:35,450 --> 02:48:35,950 from him. 3424 02:48:35,950 --> 02:48:39,040 He was very, very opposed to having something 3425 02:48:39,040 --> 02:48:42,910 big and clunky in his desk or his workspace 3426 02:48:42,910 --> 02:48:43,910 whenever he was cooking. 3427 02:48:43,910 --> 02:48:47,464 And we used that to further our designs 3428 02:48:47,464 --> 02:48:49,880 and make sure that we go with something smaller, something 3429 02:48:49,880 --> 02:48:54,190 that doesn't get in the way and is very easy for him to use. 3430 02:48:54,190 --> 02:48:56,300 And after that, we showed him some 3431 02:48:56,300 --> 02:48:59,680 of the things that he may want to use for moving a pot. 3432 02:48:59,680 --> 02:49:02,980 So over here, we can see something 3433 02:49:02,980 --> 02:49:06,870 that can adjust to a pot and use some sort of strap 3434 02:49:06,870 --> 02:49:09,620 around his forearm or shoulder to move the pot. 3435 02:49:09,620 --> 02:49:13,040 Because he mentioned that he has some what we thought 3436 02:49:13,040 --> 02:49:15,540 were really big pots to move around 3437 02:49:15,540 --> 02:49:16,990 for a pretty long distance. 3438 02:49:16,990 --> 02:49:19,073 This was before we actually went over to his house 3439 02:49:19,073 --> 02:49:21,150 and found out what we were working with. 3440 02:49:21,150 --> 02:49:24,120 And another thing that we thought was maybe-- he 3441 02:49:24,120 --> 02:49:26,560 says he slides the pots a lot because it's a lot harder 3442 02:49:26,560 --> 02:49:28,057 for him to carry them. 3443 02:49:28,057 --> 02:49:29,640 Something that we thought of was maybe 3444 02:49:29,640 --> 02:49:32,670 having a little mobile station for him to use, 3445 02:49:32,670 --> 02:49:36,910 where he can slide the pot onto it, slide it across the floor, 3446 02:49:36,910 --> 02:49:41,340 and then move it onto the actual stove itself. 3447 02:49:41,340 --> 02:49:44,540 And finally, this is just some brainstorming/prototyping. 3448 02:49:44,540 --> 02:49:48,780 We thought of like those things that drummers use, 3449 02:49:48,780 --> 02:49:50,330 where they attach it to their chest, 3450 02:49:50,330 --> 02:49:51,560 and you can pot in there. 3451 02:49:51,560 --> 02:49:54,020 But this is just for brainstorming. 3452 02:49:54,020 --> 02:49:55,780 We just threw ideas out there. 3453 02:49:55,780 --> 02:49:57,430 And we showed these ideas to Don, 3454 02:49:57,430 --> 02:50:00,130 and we decided that we were going 3455 02:50:00,130 --> 02:50:05,190 to go much further into the actual movement of the pot, 3456 02:50:05,190 --> 02:50:06,790 rather than the stirring, since he 3457 02:50:06,790 --> 02:50:09,280 says that that's one of the big challenges that he has. 3458 02:50:09,280 --> 02:50:11,917 And that's where we are currently at. 3459 02:50:11,917 --> 02:50:14,000 We have identified the problem and know what we're 3460 02:50:14,000 --> 02:50:17,500 going to do from here on out. 3461 02:50:17,500 --> 02:50:19,130 CHRISTINA: So this past Friday we 3462 02:50:19,130 --> 02:50:21,394 actually got to go to Don's apartment 3463 02:50:21,394 --> 02:50:23,060 to actually see what his kitchen is like 3464 02:50:23,060 --> 02:50:25,090 and what his cooking environment is like. 3465 02:50:25,090 --> 02:50:27,900 And so before we were initially imagining 3466 02:50:27,900 --> 02:50:30,229 that he was using pots that were like this big 3467 02:50:30,229 --> 02:50:32,520 and that you would need to use like two hands to carry. 3468 02:50:32,520 --> 02:50:35,210 But we actually found out that they're actually 3469 02:50:35,210 --> 02:50:37,630 normal sized pots which you can carry with one hand, 3470 02:50:37,630 --> 02:50:40,940 and also the thing about his kitchen space being very small 3471 02:50:40,940 --> 02:50:46,141 made some of our initial designs not feasible. 3472 02:50:46,141 --> 02:50:48,015 So here you can see a video of Don in action. 3473 02:51:19,930 --> 02:51:21,740 So, as you can see, Don has trouble 3474 02:51:21,740 --> 02:51:24,140 moving filled pots from his sink to his stove top 3475 02:51:24,140 --> 02:51:26,056 without having some of the contents spill out. 3476 02:51:28,510 --> 02:51:32,830 And so we kind of made a sketch of his kitchen layout. 3477 02:51:32,830 --> 02:51:36,930 And so the task requirement that we decided on 3478 02:51:36,930 --> 02:51:41,670 was that we wanted to help him be able to lift 3479 02:51:41,670 --> 02:51:45,475 and move the filled pot and also not spill any of the contents. 3480 02:51:48,130 --> 02:51:51,700 And so these are success metrics. 3481 02:51:51,700 --> 02:51:55,460 Them metrics include lifting and moving the pot vertically 3482 02:51:55,460 --> 02:51:58,616 as well as horizontally, and then the amount of spill there 3483 02:51:58,616 --> 02:52:01,630 is , and also how much time it takes for him to move the pot 3484 02:52:01,630 --> 02:52:03,640 from the sink to his stove top. 3485 02:52:03,640 --> 02:52:10,400 And so we kind of evaluated the current state of how 3486 02:52:10,400 --> 02:52:16,080 he accomplishes the task, and we used a scale from 1 to 10, 3487 02:52:16,080 --> 02:52:18,730 one being we would really like to help 3488 02:52:18,730 --> 02:52:23,120 him improve in this aspect, and 10 being this is OK, 3489 02:52:23,120 --> 02:52:24,350 and this is great. 3490 02:52:24,350 --> 02:52:30,877 So we have our current goals, or we have the current situation, 3491 02:52:30,877 --> 02:52:31,835 and we have the target. 3492 02:52:31,835 --> 02:52:33,293 And we also have our reached goals. 3493 02:52:37,660 --> 02:52:40,310 So our contributions up to date-- 3494 02:52:40,310 --> 02:52:44,180 since we haven't really gotten into the prototyping part yet, 3495 02:52:44,180 --> 02:52:47,110 we have all been designing and brainstorming together. 3496 02:52:47,110 --> 02:52:49,910 And so Jan has been facilitating the meetings. 3497 02:52:49,910 --> 02:52:53,190 Eann has been documenting and taking notes, 3498 02:52:53,190 --> 02:52:57,210 and I have been taking videos and also photos. 3499 02:52:57,210 --> 02:52:59,790 And for our future contributions, 3500 02:52:59,790 --> 02:53:02,920 we are going to continue doing what we're doing right now. 3501 02:53:02,920 --> 02:53:07,660 Also, once we get a better idea of what are design will be, 3502 02:53:07,660 --> 02:53:10,400 maybe split up the tasks for what 3503 02:53:10,400 --> 02:53:12,224 different components of our product 3504 02:53:12,224 --> 02:53:13,682 that we are going to be working on. 3505 02:53:18,670 --> 02:53:22,660 So I guess like our most crucial step 3506 02:53:22,660 --> 02:53:25,320 is our next step, which is like in the immediate future. 3507 02:53:25,320 --> 02:53:27,820 So we really need to be able to come up 3508 02:53:27,820 --> 02:53:30,836 with a design for our first prototype and get it to Don 3509 02:53:30,836 --> 02:53:31,960 and get his feedback on it. 3510 02:53:31,960 --> 02:53:35,950 So one of the main things that we will be focusing on 3511 02:53:35,950 --> 02:53:39,050 for this first prototype will be mechanisms and concepts 3512 02:53:39,050 --> 02:53:42,080 for how he can move a pot from a certain height 3513 02:53:42,080 --> 02:53:45,220 to a higher place. 3514 02:53:45,220 --> 02:53:47,320 And also, we might be considering the material 3515 02:53:47,320 --> 02:53:50,120 that we will be using the product because that 3516 02:53:50,120 --> 02:53:55,160 relates to, I guess, like how much mass he can move. 3517 02:53:55,160 --> 02:53:59,260 And we will also be doing a more quantitative evaluation 3518 02:53:59,260 --> 02:54:02,600 of Don's skills, so maybe like how much mass he can life, 3519 02:54:02,600 --> 02:54:04,418 or how long can he hold up a pot for. 3520 02:54:10,280 --> 02:54:14,520 And so I these are our project plans. 3521 02:54:14,520 --> 02:54:17,440 So, as I mentioned before, our main thing right now 3522 02:54:17,440 --> 02:54:20,200 is to get our first prototype out and get his feedback on it. 3523 02:54:20,200 --> 02:54:23,170 And then from then on, we can add more details 3524 02:54:23,170 --> 02:54:26,578 into our planning for how we are going to finish this product. 3525 02:54:35,061 --> 02:54:37,347 PROFESSOR 5: Any questions? 3526 02:54:37,347 --> 02:54:38,055 Great, thank you. 3527 02:54:43,070 --> 02:54:45,500 PROFESSOR 6: Did he articulate any other scenarios 3528 02:54:45,500 --> 02:54:49,340 of where her would move the pot, aside from stove to sink? 3529 02:54:52,134 --> 02:54:53,800 JAN: No, that's the only one we actually 3530 02:54:53,800 --> 02:54:55,700 saw him doing physically. 3531 02:54:55,700 --> 02:54:59,790 But I imagine that he would have to potentially move something 3532 02:54:59,790 --> 02:55:02,400 that has like maybe spaghetti to cool it down somewhere else 3533 02:55:02,400 --> 02:55:06,970 and maybe actually serving my the pot, so from his 3534 02:55:06,970 --> 02:55:07,967 to the kitchen table. 3535 02:55:07,967 --> 02:55:10,050 But that's the only one we actually saw him doing, 3536 02:55:10,050 --> 02:55:12,870 and that's why we are going to get some further tests to see 3537 02:55:12,870 --> 02:55:15,530 distance, weight, and other things that could potentially 3538 02:55:15,530 --> 02:55:16,750 play into our design. 3539 02:55:16,750 --> 02:55:18,250 PROFESSOR 6: So I was wondering that 3540 02:55:18,250 --> 02:55:21,030 about how that may impact your metrics 3541 02:55:21,030 --> 02:55:24,430 or quantitative metrics of being able to move it three feet. 3542 02:55:24,430 --> 02:55:26,130 AUDIENCE: Maybe you want to try to try 3543 02:55:26,130 --> 02:55:29,945 to get him to fill the pot and move it 3544 02:55:29,945 --> 02:55:33,780 while there's hot liquid because that may make a big difference. 3545 02:55:33,780 --> 02:55:36,850 And he was very aloof about splashing cold water, 3546 02:55:36,850 --> 02:55:39,337 but he might not want to do that with boiling water. 3547 02:55:39,337 --> 02:55:41,420 JAN: No, we didn't want anybody to get hurt there. 3548 02:55:44,407 --> 02:55:46,365 AUDIENCE: Did you guys try the pot-moving thing 3549 02:55:46,365 --> 02:55:50,709 yourselves to see how much-- you filled 3550 02:55:50,709 --> 02:55:52,000 the pot all the way to the top. 3551 02:55:52,000 --> 02:55:55,920 How feasible is it for like one of you to do that? 3552 02:55:55,920 --> 02:55:56,900 JAN: No, we did not. 3553 02:55:56,900 --> 02:55:57,976 It's something that we should have done. 3554 02:55:57,976 --> 02:55:58,790 You're right. 3555 02:56:03,549 --> 02:56:05,840 PROFESSOR 5: So imagine everything goes amazingly well. 3556 02:56:05,840 --> 02:56:07,212 What will you actually make? 3557 02:56:07,212 --> 02:56:08,384 What will you actually do? 3558 02:56:08,384 --> 02:56:09,550 Will it be a redesigned pot? 3559 02:56:09,550 --> 02:56:12,530 Is it sort of like thinking about the procedure 3560 02:56:12,530 --> 02:56:15,010 of how to do these tasks? 3561 02:56:15,010 --> 02:56:17,670 You can imagine building a robot that could do it. 3562 02:56:17,670 --> 02:56:20,564 It would be like really hard. 3563 02:56:20,564 --> 02:56:21,980 What are you actually going to do? 3564 02:56:21,980 --> 02:56:24,130 JAN: So what really thought was an attachment 3565 02:56:24,130 --> 02:56:27,620 that you can adjust to almost any type of pot. 3566 02:56:27,620 --> 02:56:29,530 So one that I showed over there was something 3567 02:56:29,530 --> 02:56:32,050 that you can put around the top side of the pot, 3568 02:56:32,050 --> 02:56:36,960 so a belt or some type of thing, where 3569 02:56:36,960 --> 02:56:38,480 it hooks on to the top of the pot, 3570 02:56:38,480 --> 02:56:42,630 and you have belt on top of it, where he can-- 3571 02:56:42,630 --> 02:56:45,110 he says he would really like to be able to really use 3572 02:56:45,110 --> 02:56:47,650 his forearm because his fingers also get really tired, to be 3573 02:56:47,650 --> 02:56:52,320 able to put the belt over his arm and then carry it over, 3574 02:56:52,320 --> 02:56:53,923 using that, rather than the handle, 3575 02:56:53,923 --> 02:56:55,589 where he doesn't have as much stability. 3576 02:56:58,971 --> 02:57:01,220 PROFESSOR 1: I do want to echo what was said over here 3577 02:57:01,220 --> 02:57:02,460 about heat. 3578 02:57:02,460 --> 02:57:04,650 I think that the fact that you didn't mentioned 3579 02:57:04,650 --> 02:57:07,890 that at all in your success metrics or in your constraints 3580 02:57:07,890 --> 02:57:10,060 is actually a pretty serious problem, right? 3581 02:57:10,060 --> 02:57:14,070 He's moving a pot to his sink-- I'm sorry to the stove 3582 02:57:14,070 --> 02:57:16,302 in order to heat it up. 3583 02:57:16,302 --> 02:57:18,510 And then if he's going to continue to be independent, 3584 02:57:18,510 --> 02:57:19,926 he's going to have to do something 3585 02:57:19,926 --> 02:57:23,270 with that hot, still heavy pot. 3586 02:57:23,270 --> 02:57:26,372 So you need a consideration here which is 3587 02:57:26,372 --> 02:57:27,580 that he doesn't burn himself. 3588 02:57:30,410 --> 02:57:32,810 And I think that spillage may be something 3589 02:57:32,810 --> 02:57:36,300 that you should give a little less concern to because that 3590 02:57:36,300 --> 02:57:40,182 can be solved by not filling it up as much because that would 3591 02:57:40,182 --> 02:57:42,682 boil over anyway, if you filled it up as much as he actually 3592 02:57:42,682 --> 02:57:46,370 did in that video or by putting lids on it. 3593 02:57:46,370 --> 02:57:48,690 But I really would encourage you to worry much more 3594 02:57:48,690 --> 02:57:52,549 and pay much more attention to the problem of heat. 3595 02:57:52,549 --> 02:57:54,340 JAN: That's something that we'll definitely 3596 02:57:54,340 --> 02:57:54,770 take into account then. 3597 02:57:54,770 --> 02:57:56,270 AUDIENCE: Especially if you're going 3598 02:57:56,270 --> 02:57:58,450 in the direction of putting something 3599 02:57:58,450 --> 02:58:01,430 that's close to his body. 3600 02:58:01,430 --> 02:58:05,730 And you can do tests with him not burning him, 3601 02:58:05,730 --> 02:58:07,251 like put food coloring. 3602 02:58:07,251 --> 02:58:09,500 Have him wear something he doesn't care about, and see 3603 02:58:09,500 --> 02:58:12,650 if he an immediate reflex if he's spilling food coloring 3604 02:58:12,650 --> 02:58:13,440 on his clothes. 3605 02:58:13,440 --> 02:58:16,650 It'll give you a better sense of is he really 3606 02:58:16,650 --> 02:58:19,600 that confident with this forearm, for instance. 3607 02:58:19,600 --> 02:58:21,740 PROFESSOR 5: So it's a really hard problem. 3608 02:58:21,740 --> 02:58:23,890 In some ways, I'll just be honest, 3609 02:58:23,890 --> 02:58:26,760 like when I first saw this compelling client, 3610 02:58:26,760 --> 02:58:30,210 and it's like, this is a great person. 3611 02:58:30,210 --> 02:58:32,290 It would be great to help him, and I 3612 02:58:32,290 --> 02:58:33,770 know that he loves to cook. 3613 02:58:33,770 --> 02:58:38,770 But dealing with pots full of water, possibly hot water, 3614 02:58:38,770 --> 02:58:40,710 that just seems like a really hard problem. 3615 02:58:40,710 --> 02:58:42,890 And I wonder if there's something else 3616 02:58:42,890 --> 02:58:47,250 you can do for him that's not so physically, like something 3617 02:58:47,250 --> 02:58:49,791 that doesn't have a safety dimension. 3618 02:58:49,791 --> 02:58:51,290 You don't want to give him something 3619 02:58:51,290 --> 02:58:53,331 he's going to burn himself with badly on his own. 3620 02:58:53,331 --> 02:58:54,909 You know what I mean? 3621 02:58:54,909 --> 02:58:57,200 JAN: Yeah, we could also take the alternative approach, 3622 02:58:57,200 --> 02:59:00,794 the actual stirring or moving the things within the pot. 3623 02:59:00,794 --> 02:59:02,210 PROFESSOR 5: Or maybe he just lets 3624 02:59:02,210 --> 02:59:03,600 it cool for a really long time. 3625 02:59:03,600 --> 02:59:05,010 But how do you get the food out? 3626 02:59:05,010 --> 02:59:05,460 I don't know. 3627 02:59:05,460 --> 02:59:07,584 Maybe there's a way to rethink the entire-- I mean, 3628 02:59:07,584 --> 02:59:09,540 the goal is to have cooked food. 3629 02:59:09,540 --> 02:59:11,870 Is there a way to rethink how you get cooked food 3630 02:59:11,870 --> 02:59:13,747 at the end of the day that avoids lifting 3631 02:59:13,747 --> 02:59:14,830 a heavy pot from the sink. 3632 02:59:14,830 --> 02:59:16,372 AUDIENCE: Have a longer hose. 3633 02:59:16,372 --> 02:59:18,580 AUDIENCE: That's another way to do the filling right? 3634 02:59:18,580 --> 02:59:19,536 PROFESSOR 5: You can imagine filling it 3635 02:59:19,536 --> 02:59:21,240 with like small-- you know, a ferry 3636 02:59:21,240 --> 02:59:22,706 system of smaller things that get 3637 02:59:22,706 --> 02:59:23,914 added a little bit at a time. 3638 02:59:23,914 --> 02:59:25,000 AUDIENCE: Or an interesting pump [INAUDIBLE]. 3639 02:59:25,000 --> 02:59:27,542 PROFESSOR 5: If you can sort of train him how to do the task. 3640 02:59:27,542 --> 02:59:29,166 I wonder if there are experts out there 3641 02:59:29,166 --> 02:59:31,090 in the world that figure out how to do this. 3642 02:59:31,090 --> 02:59:33,700 Disabled cooking, is there such a thing? 3643 02:59:33,700 --> 02:59:35,196 But I admire you for taking it on. 3644 02:59:35,196 --> 02:59:38,351 It just seems really hard and dangerous. 3645 02:59:38,351 --> 02:59:40,017 PROFESSOR 4: Great, thank you, Team Don. 3646 02:59:40,017 --> 02:59:40,558 Thanks again. 3647 02:59:44,490 --> 02:59:46,814 We managed to get through them all. 3648 02:59:46,814 --> 02:59:48,480 We have maybe two or three minutes left. 3649 02:59:48,480 --> 02:59:51,710 Maybe I'll ask if the panelists or the support staff 3650 02:59:51,710 --> 02:59:55,600 have general comments on all the presentation today, 3651 02:59:55,600 --> 02:59:56,910 for the panelists here today. 3652 02:59:56,910 --> 02:59:59,800 And Professor Miller, if you have general comments or advice 3653 02:59:59,800 --> 03:00:03,490 on the presentations or the project progress in general, 3654 03:00:03,490 --> 03:00:04,990 give you the opportunity to do that. 3655 03:00:07,350 --> 03:00:10,580 But while you think about that, just one reminder 3656 03:00:10,580 --> 03:00:13,810 is to remember to upload your slides from the presentation 3657 03:00:13,810 --> 03:00:20,132 today, so that we can integrate these things into the video, 3658 03:00:20,132 --> 03:00:22,090 and so that we can look at your slides as well. 3659 03:00:22,090 --> 03:00:23,940 And then the reports are due Friday, 3660 03:00:23,940 --> 03:00:27,160 and then next week, we'll have read all the reports, 3661 03:00:27,160 --> 03:00:30,470 and we'll give you some more written feedback, a letter 3662 03:00:30,470 --> 03:00:34,140 grade at this point in time. 3663 03:00:34,140 --> 03:00:36,141 But I'll of the panelists, Jose or Anna, 3664 03:00:36,141 --> 03:00:37,640 Professor Leonard, Professor Miller, 3665 03:00:37,640 --> 03:00:41,670 if you have any general comments or advice for teams 3666 03:00:41,670 --> 03:00:43,444 at this point in time. 3667 03:00:43,444 --> 03:00:45,860 PROFESSOR 1: Great to see the progress that you're making. 3668 03:00:45,860 --> 03:00:48,920 Keep meeting with your clients, and focus 3669 03:00:48,920 --> 03:00:51,630 on trying to finish that prototype that you're 3670 03:00:51,630 --> 03:00:53,824 going to deliver at the end of the semester. 3671 03:00:53,824 --> 03:00:55,490 PROFESSOR 5: I would just say, like I've 3672 03:00:55,490 --> 03:00:57,590 taught design classes and mechanical and ocean 3673 03:00:57,590 --> 03:01:00,480 engineering, and it's really challenging 3674 03:01:00,480 --> 03:01:03,720 when the schedule crunch at the end of the semester, 3675 03:01:03,720 --> 03:01:05,670 and so sometimes you're going to have 3676 03:01:05,670 --> 03:01:07,240 to down scope towards the end. 3677 03:01:07,240 --> 03:01:10,279 But if you try to really think about a measurable result, 3678 03:01:10,279 --> 03:01:11,820 that you really accomplish something, 3679 03:01:11,820 --> 03:01:14,490 and what that would be, and make sure you at least get that far. 3680 03:01:14,490 --> 03:01:17,840 Like it would be a disaster if you didn't at least do x. 3681 03:01:17,840 --> 03:01:18,730 What is x? 3682 03:01:18,730 --> 03:01:22,817 Have a prototype that does something, that gives 3683 03:01:22,817 --> 03:01:23,900 some value to your client. 3684 03:01:23,900 --> 03:01:26,510 And so the time's going to go really quickly, 3685 03:01:26,510 --> 03:01:30,125 and you're going to run out of time. 3686 03:01:30,125 --> 03:01:32,250 PROFESSOR 6: I would say it's great to that you all 3687 03:01:32,250 --> 03:01:34,660 are meeting what seems like a regular basis 3688 03:01:34,660 --> 03:01:37,700 with your collaborators for these projects. 3689 03:01:37,700 --> 03:01:39,200 And so take advantage of every time 3690 03:01:39,200 --> 03:01:41,390 you're meeting with them to bring something 3691 03:01:41,390 --> 03:01:44,210 you can hold in your hand that is going to impact 3692 03:01:44,210 --> 03:01:46,570 the final design, whether a potential material 3693 03:01:46,570 --> 03:01:49,960 you could use, a prototype of a looks-like design, 3694 03:01:49,960 --> 03:01:51,420 or this is a feature design. 3695 03:01:51,420 --> 03:01:53,430 But that'll really help you to continue 3696 03:01:53,430 --> 03:01:54,920 to iterate on those features. 3697 03:01:58,250 --> 03:02:01,520 AUDIENCE: I would echo Professor Leonard's comments 3698 03:02:01,520 --> 03:02:03,120 of take something. 3699 03:02:03,120 --> 03:02:06,820 If you're going towards the end of the semester, 3700 03:02:06,820 --> 03:02:08,736 pick that one item that you know is going 3701 03:02:08,736 --> 03:02:11,300 to make a critical difference. 3702 03:02:11,300 --> 03:02:15,330 If you spend too much time picking pots, 3703 03:02:15,330 --> 03:02:18,250 we know what pots look like, and how they behave. 3704 03:02:18,250 --> 03:02:21,390 But if you don't know how another mechanism that you're 3705 03:02:21,390 --> 03:02:23,720 designing behaves, then focus on that one. 3706 03:02:23,720 --> 03:02:27,660 And just in case you do run out of time, 3707 03:02:27,660 --> 03:02:31,170 you know that that's an addressable thing to leave out. 3708 03:02:31,170 --> 03:02:33,780 Don't leave out the [? core ?] [INAUDIBLE]. 3709 03:02:33,780 --> 03:02:35,530 PROFESSOR 4: Michelle, [INAUDIBLE], Grace, 3710 03:02:35,530 --> 03:02:37,140 you have general comments? 3711 03:02:39,720 --> 03:02:40,640 OK, cool. 3712 03:02:40,640 --> 03:02:42,930 I think one thing I'll say is I think you all 3713 03:02:42,930 --> 03:02:45,420 have gotten to know your clients really well, 3714 03:02:45,420 --> 03:02:47,550 from the presentations. 3715 03:02:47,550 --> 03:02:51,330 On Monday and Wednesday and on Friday night or on the weekend, 3716 03:02:51,330 --> 03:02:54,870 Grace and I watched all the videos that where submitted. 3717 03:02:54,870 --> 03:02:57,040 We're all very impressed. 3718 03:02:57,040 --> 03:02:58,750 You really have spent a lot of time 3719 03:02:58,750 --> 03:03:00,820 and really gotten to know the people. 3720 03:03:00,820 --> 03:03:02,587 One thing I would suggest is you really, 3721 03:03:02,587 --> 03:03:04,670 maybe in the next couple weeks, really, really get 3722 03:03:04,670 --> 03:03:06,900 to know the client's task. 3723 03:03:06,900 --> 03:03:08,910 I mean really break it down and come up 3724 03:03:08,910 --> 03:03:12,130 with these measurable metrics, try things out, 3725 03:03:12,130 --> 03:03:15,630 food color the water, things like that, so you can really 3726 03:03:15,630 --> 03:03:17,300 get a sense of whether your device 3727 03:03:17,300 --> 03:03:20,925 or whether the system you're building is going to work. 3728 03:03:20,925 --> 03:03:23,230 PROFESSOR 5: Like really put yourself in their shoes. 3729 03:03:23,230 --> 03:03:25,370 PROFESSOR 4: OK, I think that's pretty much it. 3730 03:03:25,370 --> 03:03:27,880 Next week we're going to do a bunch of electronic device 3731 03:03:27,880 --> 03:03:29,850 labs, so bring your laptop computer 3732 03:03:29,850 --> 03:03:31,750 is what we're hoping for people to bring. 3733 03:03:31,750 --> 03:03:33,291 Grace, you have a final announcement? 3734 03:03:33,291 --> 03:03:35,660 GRACE: Yeah, we sent out a poll today. 3735 03:03:35,660 --> 03:03:39,170 We're going to set up twice weekly hobby shop office hours. 3736 03:03:39,170 --> 03:03:42,720 So if you think you're going to be using a hobby shop 3737 03:03:42,720 --> 03:03:45,520 or building anything mechanical, please fill out the-- we'll 3738 03:03:45,520 --> 03:03:47,395 decide by Friday what those office hours are. 3739 03:03:47,395 --> 03:03:47,670 Thanks. 3740 03:03:47,670 --> 03:03:49,295 PROFESSOR 4: And Monday's class lecture 3741 03:03:49,295 --> 03:03:51,070 and lab will both be in this room 3742 03:03:51,070 --> 03:03:53,350 because we're doing these electronic device access 3743 03:03:53,350 --> 03:03:58,150 labs, so 32044 at both 1:00 PM and 3:00 PM. 3744 03:03:58,150 --> 03:03:59,700 OK, thanks.
