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.
患有多种身体障碍的人无法使用合适的指针设备，从而减少了他们通过计算机进行交流和学习的机会。本研究设计采用重复单病例实验方法，比较了两名患有言语障碍和四肢瘫痪性手足徐动型脑瘫的学生在使用四种不同的计算机访问解决方案（摄像头鼠标、美国手语头部阵列鼠标模拟器、交叉扫描仪和快速扫视眼动追踪系统）时的个人表现。结果表明，运动时间和准确性与舒适度和满意度水平之间的相关性具有统计学意义，这被用于指导临床干预中计算机访问解决方案的选择。本研究中使用的WinFitts和舒适度评估测试可重复进行，以进一步开展计算机访问系统的临床研究。
