We collaborated with Community Living and Support Services (CLASS), a local Pittsburgh nonprofit, to gain insight into the existing stage of assistive devices, proper methods and practices when working with clients that live with disabilities, and also to connect us to Keith, our client for the project.<\/p>\n<p>Keith, our client, was a machinist who suffered a traumatic head injury, resulting in headaches, reduced mobility in his left side, and forgetfulness. Beyond that, he is a lovable grouch and has an appreciation for cheesecake. We documented our initial interview with Keith <a href=\"https:\/\/courses.ideate.cmu.edu\/60-223\/s2023\/work\/interview-with-keith-team-alycia\/\">here<\/a>.<\/p>\n<h2 id=\"2-what-we-built-10-pts\">What we built<\/h2>\n<p>Keith&#8217;s Explosive Schedule Reminder is a handheld phone-sized device that reminds him of his schedule. A screen on one side displays his upcoming scheduled event and a buzzer inside beeps when event is five minutes away from starting.<\/p>\n<div id=\"attachment_18291\" style=\"width: 630px\" class=\"wp-caption aligncenter\"><img aria-describedby=\"caption-attachment-18291\" decoding=\"async\" loading=\"lazy\" class=\"wp-image-18291 size-large\" src=\"https:\/\/courses.ideate.cmu.edu\/60-223\/s2023\/work\/wp-content\/uploads\/2023\/05\/IMG_1651-1024x768.jpg\" alt=\"Bright red box with a small white screen in the center displaying details about a class\" width=\"620\" height=\"465\" srcset=\"https:\/\/courses.ideate.cmu.edu\/60-223\/s2023\/work\/wp-content\/uploads\/2023\/05\/IMG_1651-1024x768.jpg 1024w, https:\/\/courses.ideate.cmu.edu\/60-223\/s2023\/work\/wp-content\/uploads\/2023\/05\/IMG_1651-300x225.jpg 300w, https:\/\/courses.ideate.cmu.edu\/60-223\/s2023\/work\/wp-content\/uploads\/2023\/05\/IMG_1651-768x576.jpg 768w, https:\/\/courses.ideate.cmu.edu\/60-223\/s2023\/work\/wp-content\/uploads\/2023\/05\/IMG_1651-1536x1152.jpg 1536w, https:\/\/courses.ideate.cmu.edu\/60-223\/s2023\/work\/wp-content\/uploads\/2023\/05\/IMG_1651-2048x1536.jpg 2048w, https:\/\/courses.ideate.cmu.edu\/60-223\/s2023\/work\/wp-content\/uploads\/2023\/05\/IMG_1651-973x730.jpg 973w, https:\/\/courses.ideate.cmu.edu\/60-223\/s2023\/work\/wp-content\/uploads\/2023\/05\/IMG_1651-508x381.jpg 508w\" sizes=\"(max-width: 620px) 100vw, 620px\" \/><p id=\"caption-attachment-18291\" class=\"wp-caption-text\">Keith&#8217;s Explosive Schedule Reminder<\/p><\/div>\n<div id=\"attachment_18370\" style=\"width: 630px\" class=\"wp-caption aligncenter\"><img aria-describedby=\"caption-attachment-18370\" decoding=\"async\" loading=\"lazy\" class=\"wp-image-18370 size-large\" src=\"https:\/\/courses.ideate.cmu.edu\/60-223\/s2023\/work\/wp-content\/uploads\/2023\/05\/IMG_1842-1024x768.jpg\" alt=\"Red box with a small screen in the center and 7 holes to the right side, next to a plant and on an orange surface\" width=\"620\" height=\"465\" srcset=\"https:\/\/courses.ideate.cmu.edu\/60-223\/s2023\/work\/wp-content\/uploads\/2023\/05\/IMG_1842-1024x768.jpg 1024w, https:\/\/courses.ideate.cmu.edu\/60-223\/s2023\/work\/wp-content\/uploads\/2023\/05\/IMG_1842-300x225.jpg 300w, https:\/\/courses.ideate.cmu.edu\/60-223\/s2023\/work\/wp-content\/uploads\/2023\/05\/IMG_1842-768x576.jpg 768w, https:\/\/courses.ideate.cmu.edu\/60-223\/s2023\/work\/wp-content\/uploads\/2023\/05\/IMG_1842-1536x1152.jpg 1536w, https:\/\/courses.ideate.cmu.edu\/60-223\/s2023\/work\/wp-content\/uploads\/2023\/05\/IMG_1842-2048x1536.jpg 2048w, https:\/\/courses.ideate.cmu.edu\/60-223\/s2023\/work\/wp-content\/uploads\/2023\/05\/IMG_1842-973x730.jpg 973w, https:\/\/courses.ideate.cmu.edu\/60-223\/s2023\/work\/wp-content\/uploads\/2023\/05\/IMG_1842-508x381.jpg 508w\" sizes=\"(max-width: 620px) 100vw, 620px\" \/><p id=\"caption-attachment-18370\" class=\"wp-caption-text\">Keith&#8217;s Explosive Schedule Reminder<\/p><\/div>\n<p><iframe loading=\"lazy\" title=\"Final Demo\" width=\"620\" height=\"349\" src=\"https:\/\/www.youtube.com\/embed\/zk5R_PFHS8M?feature=oembed\" frameborder=\"0\" allow=\"accelerometer;

id=\"caption-attachment-18377\" class=\"wp-caption-text\">Prototype 2<\/p><\/div>\n<p>These two prototypes were designed to help answer the design question: What form and user-experience considerations are suitable for Keith&#8217;s device?<\/p>\n<p>The first prototype was created using a white board material and blue LCD screen, which cycles through Keith&#8217;s schedule every few seconds. The second prototype is fixed to a chipboard, and reads out a class description, as well as vibrating.<\/p>\n<p>The first prototype was specifically intended to show Keith what the device we were making would look like, so that we could further understand what limitations he might have towards adopting this new device. Size, readability, and usability were paramount. The second prototype was intended to show Keith what alert features we could incorporate, between audio and haptic feedback.<\/p>\n<p>Our strongest piece of feedback from Keith was that he didn&#8217;t particularly care about the device itself, but wanted it to be red and read &#8220;explosive&#8221; on it. It was a frustrating critique session because Keith wasn&#8217;t very enthusiastic about the device, but we were able to ascertain that he could not read the LCD screen due to low contrast, but did not mind the size and shape of the device we were making for him. The feedback gave us a direction to move forward, but was demoralizing due to Keith&#8217;s disinterest. We hoped that by customizing the device to his preferences, he may be more excited about his device. Something we got from Bill was that the vibration motor wasn&#8217;t as important as an audio feature. Keith may not carry the device on his person at all times, and also may be wearing too many layers to feel a vibrating motor. We decided to limit our scope and focus on audio instead.<\/p>\n<h3 id=\"b-process\">b.

Unfortunately, we did not actually receive parts until Monday the 24th, which lead to a lot of technical difficulties in the final phases of our project. We planned throughout the project to add a voice feature to the device to remind Keith of his classes, like his Alexa does at home. However, given our size limitation, we sought out an Adafruit board and music-maker in order to achieve this. We hinged our entire project on this, and the fact that we received the board so late, as well as frying it the night before, caused us to end up incorporating a buzzer and Arduino Micro instead. This decision was made out of desperation, and ideally we would have had more time to actually work with the final parts together.<\/p>\n<h2 id=\"4-conclusions-and-lessons-learned-12-pts\">4. Conclusions and lessons learned<\/h2>\n<p>Our largest realization through the making of this process was that Adafruit parts are not reliable, and that we should&#8217;ve had more contingent plans in place instead of putting our final prototype together the week before. We experienced a lot of extraneous circumstances that prevented our final product from being as successful as initially intended, but ironically had stumbled upon a product that might&#8217;ve done Keith more good on accident.<\/p>\n<p>One of the most repeated pieces of feedback we got with our device was that Keith does not need to keep his device on him at all times. It could, instead, live in his cubby all day and serve as a location to ground him. If he forgets where to go, he will always know to return to his cubby to look at the device&#8217;s screen. From both critique feedback and Keith&#8217;s own admissions, we realized the primary feature of the device should be the screen, rather than the voice reminders. If we continue with this line of feedback, we might consider investing in a larger screen so that Keith can read the screen from a longer distance, as well as having a pop-up stand that allows the device to stand up on its own. Additionally, we could consider installing a re-chargeable battery and a button to toggle between voice\/buzzer states and a muted state. These are all features that are dependent on the primary function of the device, which change based on what role it might have in Keith&#8217;s life.<\/p>\n<p>Something that we learned pretty early on was that Keith was a client that was pretty content with his life. His schedules and habits weren&#8217;t bothering him, and he wasn&#8217;t particularly enthusiastic about making any big changes. This made interviewing him difficult, as we didn&#8217;t have a great grounding point for him to focus on ideating or considering making changes. Something promising brought up during our final critique was how our &#8220;final&#8221; device felt more like a late-stage prototype. This final device could very well be a device that Keith incorporates into his life for a few weeks and gives us concrete feedback on, which we can then respond to and adjust for the next stage of the device. This could be a good step to take for Keith, or any candidate that perhaps needs something physical to actually try out, rather than just imagining, which we were having him do previously.<\/p>\n<p>The one particular strength of our final prototype was the visual design, which was something we&#8217;d identified early on as a feature that posed extremely high value to Keith in his decision to actually adopt any new technology. Creating any device to &#8220;assist&#8221; in someone&#8217;s life is by definition rather invasive, so we saw making that transition as personalized and meaningful as possible as a primary goal for whatever our device ended up being. As such, we spent a lot of time talking to him about his preferences in terms of color and decoration. In the final critique, we discussed possible expansion points for this project, and whether it had any standing as a product on mass production. IoT and such. The device can be applied to a variety of settings that choose to stay phone-free, such as summer camps or hospitals. A head administrator can hard code schedules into a series of devices using a master device or app and assign them to people. For settings specifically like CLASS, customizability for each device is paramount and can be maintained in this model.<\/p>\n<p>One last concluding tidbit to this story is the fact that Keith loved his device. He was absolutely blown away by it, even though it was not necessarily to the fidelity that we had hoped we would be able to present. It just goes to show how much customizability matters when creating personalized devices, and would likely increase the device&#8217;s effectiveness tenfold (if we actually got it to work).<\/p>\n<div id=\"attachment_18354\" style=\"width: 650px\" class=\"wp-caption aligncenter\"><img aria-describedby=\"caption-attachment-18354\" decoding=\"async\" loading=\"lazy\" class=\"size-full wp-image-18354\" src=\"https:\/\/courses.ideate.cmu.edu\/60-223\/s2023\/work\/wp-content\/uploads\/2023\/05\/DSC01339.jpg\" alt=\"An older man (Keith) giving a thumbs up\" width=\"640\" height=\"428\" srcset=\"https:\/\/courses.ideate.cmu.edu\/60-223\/s2023\/work\/wp-content\/uploads\/2023\/05\/DSC01339.jpg 640w, https:\/\/courses.ideate.cmu.edu\/60-223\/s2023\/work\/wp-content\/uploads\/2023\/05\/DSC01339-300x201.jpg 300w, https:\/\/courses.ideate.cmu.edu\/60-223\/s2023\/work\/wp-content\/uploads\/2023\/05\/DSC01339-508x340.jpg 508w\" sizes=\"(max-width: 640px) 100vw, 640px\" \/><p id=\"caption-attachment-18354\" class=\"wp-caption-text\">Keith&#8217;s Thumbs Up<\/p><\/div>\n<h2 id=\"5-technical-details-10-pts\">5.
