Sara Hendren is an artist, designer and educator. Sara led a workshop exploring prosthetics and adaptive technologies, but probably not in the way we think. Extensions, proxies, augmentations, and design at all scales can be understood as “assistive tech,” and the contemporary definitions of disability and normalcy are very much in flux. Sara and the students talked together about all the prosthetics that are hiding in plain sight, and then investigated the city for evidence of design features that are variously flexible or rigid, welcoming or a hindrance, as its structures meets its many city users. The students then designed some quick experimental prototypes for investigating normal—in their own experiences and among those they observed.
