This study designed an alternative Chinese keyboard layout for single-digit typists and evaluated the efficacy of this innovative layout design. The new eight row by five column keyboard layout was designed based on the principles of alternative keyboard design. Eight college students with proficient keyboarding were involved in this study. The repeated measurement experimental design was used to compare the speed and accuracy of keystroke among the four different keyboard patterns: QWERTY, Alternative, Revised-QWERTY, and Random-Alternative. The experimental results indicated that the subjects’ typing speed is fastest when utilizing the QWERTY layout (63.86 symbols/minute), followed by the Alternative (56.02 symbols/minute), Revised QWERTY (53.39 symbols/minute) and the Random-Alternative keyboard (49.94 symbols/minute). There is no significant difference among QWERTY, Alternative, Revised-QWERTY, and Random-Alternative layouts on the subjects’ typing accuracy. The possible causes of the unpredicted results and suggestions for further studies were discussed.

The purpose of this study is to systematically investigate the effects of keyboard adaptations for children with cerebral palsy. Twelve children aged from 7 to 15 years old participated in this study. Keyboard adaptation strategies were developed based on the individualized assessments. A group comparison experimental design was selected to examine the effectiveness of keyboard adaptations. Speed and accuracy of typing Chinese were compared before and after keyboard adaptations. The results indicated that children with cerebral palsy did increase their typing performance after implementing keyboard adaptation strategies. The results of this study can provide health and educational profession a reference when serving children with physical disabilities.

This study presents a computerized assessment approach for evaluating a subject’s pointing and selecting proficiency using computer input tools, to aid access tool selection for users with severe disabilities. The CAT system consists of three subsystems. The CAT system not only provides clinicians with an objective means of evaluating clients’ specific mouse operating difficulties, but also allows them to compare the performance improvement made by a client make during the device selection and training period. The client’s performance in each assessment task is assessed on the basis of speed, accuracy and efficiency. Besides introducing the CAT system, this study also describes an example of adopting the CAT system to assist a client to select a suitable pointing device.
