Abstract

The increased use of computers has introduced a variety kind of human-computer interfaces. Mouse is one of the useful interface tools to place the cursor on the desired position on the monitor. This paper suggested a foot controlled isotonic mouse which was similar to the ordinary hand-controlled mouse except that positioning was controlled by the right foot and the clicking was performed by the left foot. Experimental results showed that both the index of difficulty(IOD) and the display-control gain(DC gain) varied the total movement time in a target acquisition task on the monitor. The present authors also drew the optimal display-control gain of the foot-controlled isotonic mouse over the index of difficulty of 1.0 to 3.0. The optimal display-control gain, i. e., 0.256, could be used when designing a foot-controlled isotonic mouse.
