This paper describes a study examining the usability of OnScreenDualScribe (OSDS), a tool to support individuals with physical disabilities with text entry and cursor movement. A portable numeric keypad is used to interact with the OSDS, which can either be held by the user, or can be affixed to a surface for interaction. A study to determine the feasibility of the system was conducted with three individuals with physical disabilities. While it was noted that the time taken was higher to complete a task compared to their existing methods of computer-based input, findings also indicate that the system offers potential for tasks involving a combination of text entry and cursor movement (e.g., completing online forms). Furthermore, as the keypad is smaller in size compared with a traditional keyboard, participants suggested that it offered potential to reduce effort spent in the fatiguing process of traversal.
