Touchscreen computing devices such as the iPhone are becoming more common. However this technology is largely inaccessible to people with visual impairments. We present the results of a requirements capture study that illustrates the problems with touchscreen accessibility, and the choices visually impaired people make when choosing assistive technology. We investigate ways of overcoming touchscreen accessibility problems by comparing a raised paper overlay touchscreen based MP3 player, with a touchscreen gesture based player. Twelve blindfolded participants, and one visually impaired person, were able to operate both players, though there were problems with short impact related operations in the gesture player. From our results we provide guidelines for future designers, to help them exploit the potential of touchscreen technology for visually impaired people.
