iGYM: A Wheelchair-Accessible Interactive Floor Projection System for Co-located Physical Play

Physical play opportunities for people with motor disabilities typically do not include co-located play with peers without disabilities in traditional sport settings. In this paper, we present a prototype of a wheelchair-accessible interactive floor projection system, iGYM, designed to enable people with motor disabilities to compete on par with, and in the same environment as, peers without disabilities. iGYM provides two key system features-peripersonal circle interaction and adjustable game mechanic (physics)-that enable individualized game calibration and wheelchair-accessible manipulation of virtual targets on the floor. Preliminary findings from our pilot study with people with motor disabilities using power wheelchairs, manual wheelchairs, and people without disabilities showed that the prototype system was accessible for all participants at higher than anticipated target speeds. Our work has implications for designing novel, physical play opportunities in inclusive traditional sport settings.
