Abstract

This research study focuses on evaluating the usability of multi-touch tablet devices by adults with Down syndrome for workplace-related tasks. The usability evaluation involved 10 adults with Down syndrome, and the results of the study illustrate that (a) adults with Down syndrome are able to use multi-touch devices effectively for workplace-related tasks, (b) formal computer training seems to impact participant performance, and (c) password usability continues to be a challenge for individuals with Down syndrome. Implications for designers, for policymakers, for researchers, and for users are discussed, along with suggestions for effective implementation of usability testing when involving adults with Down syndrome. Information technology can be a potential workplace skill for adults with Down syndrome, and more of the user experience community needs to get involved in understanding how people with Down syndrome utilize technology.
