<p>PURPOSE:To eliminate a puzzle accompanying cursor moving operation by returning a cursor display to a fixed position by regular operation, i.e. the gripping of a position and movement information input device (mouse). CONSTITUTION:A proximity detection type sensor 10 is mounted on the grip part of the position and movement information input device 6 and a control means (CPU) which returns the cursor to the fixed position on the display part is provided. Then an operation start state is entered by switch input and when the mouse 6 is operated, a window 8 is covered with the hand in a natural state and infrared rays emitted by an infrared-ray sensor 10 are reflected by the palm of the hand and its reflected signal is photodetected to send a signal indicating that the operation is started to a CPU. The program incorporated in the CPU returns the cursor display to the fixed position with said signal. Consequently, the operation can started in the same state at all times.</p> |
