<p>PROBLEM TO BE SOLVED: To prevent input operation from being broken even when a position to be inputted moves by displaying an input position mark on a screen according to the position of a foot, moving the input position mark as, the foot position moves, and making an operator inputs data at the display position of the input position mark. SOLUTION: A terminal device of a computer which has a screen and a keyboard senses the position of the foot of a terminal operator (step 1), displays the input position mark on the screen according to the sensed position of the foot (step 2), and moves the input position mark as the foot position moves (step 3), and the operator inputs data at the display position of the input position mark (step 4). When the input position mark is displayed, the horizontal movement of the operator's foot is sensed and the input position mark is moved according to the sensed movement. Consequently, there is no break until the input position mark moves to a desired position.</p> |
