The Use of Working Prototypes for Participatory Design with People with Disabilities
The inclusion of people with disabilities and their circle of stakeholders in the design and deployment of digital assistive technology is increasingly being recognized as important. The Do-It-Yourself Assistive Technology (DIY-AT) approach investigates methodologies and tools to support accessible making practices. In prior work, we successfully used a DIY-AT approach to develop TalkBox, an open-source direct-selection communication board for those with little or no functional verbal communication. In this paper, we describe a follow-up project in which we use TalkBox as a prototyping platform to facilitate co-design and co-fabrication of DIY-AT. We present results from (1) a workshop in which users with disabilities and their parents/caregivers fabricated their own TalkBoxes, and (2) a collaborative co-design session with a non-verbal child and his mother wherein the potential for TalkBox variants led to novel design decisions. We illustrate the outcome of our process by describing the multi-vocabulary variant called Hot Swappable TalkBox, in which RFID technology is used to afford easy switching among different vocabulary sets.
