Abstract

This paper described a system which could measure cursor movement and control site motion simultaneously. In addition to evaluate a client's pointing and selecting proficiency, CAT Motor system, developed on the basis of the previous CAT system, was also used to detect the motion of his control site. This feature could provide clinical professionals more detailed information when comparing the difference of performance among devices. The CAT Motor system consisted of four basic types of mouse operating skills, including clicking, cursor moving, cursor moving and clicking, and dragging. The CAT Motor recorded the location and the response of the pointing device and captured the picture of the control site synchronally. Then, the system visualized the results of cursor moving and control site motion on the screen. The CAT Motor system not only provided the professionals with an objective mean of evaluating specific difficulties of mouse operating difficulties, but also allowed them to evaluate the effort of the motor control training. Besides, this paper had some suggestions for the research in the future.
