2C3-3 The Movement Time and Optimal Control-Display Ratio of Foot-Controlled Isotonic Mouse

抄録

This paper experimentally derived the optimal control-display ratio and the expected movement time of the foot-controlled isotonic mouse that positioning was controlled by a right pedal and clicking was performed by a left pedal. The results showed that both the index of difficulty and the control-display ratio varied the total movement time in a target acquisition task on the monitor. The optimal control-display ratio 0 was 3.76 in the index of difficulty below 3.0. The results could be used in design of a foot-controlled isotonic mouse for the arm-impaired users.
