PURPOSE: A mouse cursor display method is provided to prevent a third person from recognizing information inputted by a user through screen hacking or peeping into a screen, by simultaneously displaying an actual and a virtual mouse cursor on a virtual keypad on a screen. CONSTITUTION: A control unit displays an actual mouse cursor(31) and virtual mouse cursors(32~34) on a screen. When a pointing unit moves, the control unit displays the actual mouse cursor on an actual mouse cursor coordinate display by calculating where the cursor is supposed to be, based on the motion path of the pointing unit, on the display on a screen. The control unit displays the virtual mouse cursors on a virtual mouse cursor coordinate display by calculating where those virtual cursors, of which motion path is different from that of the pointing unit, are supposed to be. The control unit processes the selective input of a virtual key corresponding to the position of the actual mouse cursor. |
