<p>PROBLEM TO BE SOLVED: To quickly move a cursor for a long distance with hands on a keyboard by finely adjusting the cursor position after using an optical signal to move the cursor for a long distance. SOLUTION: A laser beam sensing screen 130 is arranged on a display device 160, and a headphone type laser beam emitting device 120 is turned in the same direction of worker's front gaze and is fixed to his head. When the worker depresses an input key 111 for long-distance movement, a trigger signal 115 is generated, and the laser beam emitting device 120 outputs laser beam 125. The laser beam sensing screen 130 senses the laser beam 125 by plural sensors 131 and outputs moving direction information 135 to a cursor position control part 141 on a memory 140. When the position of the cursor on a display device 160 is finely adjusted after the cursor is moved for a long distance by the cursor position control part 141, coordinates of the cursor are inputted by a track ball 112, and the position of the cursor is finely adjusted by a CPU 150.</p> |
