Abstract

The Ann Arbor Center for Independent Living (AACIL), an organization led by people with disabilities to empower the lives of people with disabilities, wants an electronic input/output device that gives a unique sensory experience for their members. The device must map user inputs to outputs, enabling users with varying levels of ability to interact with the device and giving them autonomy in the final output of the device. This need was identified by our three primary stakeholders: Sean Ahlquist (A. Alfred Taubman College of Architecture and Urban Planning Professor), Claire Moore (AACIL’s Visual Arts teacher), and an AACIL Visual Arts participant. Through an ideation phase, screening using requirements and specifications, and evaluation using a Pugh chart, we selected our final design: an input/output device that manipulates a textile to alter the projections of lights shining through the textile. Based on a theoretical model of the system, experiments to characterize the interaction between lights and textiles, and preliminary electrical analysis, we created a detailed CAD model. We then moved into manufacturing, ordering purchased components, and assembly. We conducted extensive user testing and verification of our requirements and specifications. The team verified 8 of our 10 requirements, including our user engagement and accessibility requirements. Some of our requirements were not met due to time and budget limitations, including durability and safety labeling. Overall, the device achieved its purpose of providing an accessible, interactive, engaging input/output device for self-expression.
