Fundamental study of pointing motion characteristics

Since user always operates the mouse using cursor position as a feedback, C-D ratio (an indicator for determining the speed of the cursor) has a major effect on visual-motor control give in pointing reaching movement. Until now, various studies on C-D ratio have been done, all of them only evaluated efficiency of appropriate C-D ratio pointing time, pointing arrival process hasn`t been discussed.
In our study, by the analysis of movement characteristics such as speed distribution in the human pointing, for the purpose of setting the guidelines of appropriate C-D ratio pointing, we investigate motion planning and tradeoff relationship between pointing time and intuitive operation.
