Abstract

People with multiple physical impairments are not capable of using proper pointer devices, thus diminishing their opportunities to communicate and learn through computers. This research design used a replicated single-case experimental approach to compare the individual performance of two students with speech impairments and quadriplegic athetoid cerebral palsy in using four different computer-access solutions (the CameraMouse, the ASL Head Array mouse emulator, the CrossScanner, and the Quick Glance Eye Tracking System). The results demonstrate statistical significance in the correlation of movement time and accuracy to the level of comfort and satisfaction, which was used to guide the selection of computer-access solutions for clinical interventions. The WinFitts and Assessment of Comfort tests used in this study can be replicated for further clinical research into computer-access systems.
