<p>PROBLEM TO BE SOLVED: To improve the operability by automatically displaying menu items by slight operation for only fixing an input pen on a screen for a certain time. SOLUTION: An elapsed time measurement processing part 13 measures the time elapsed after a pen tip part is brought into contact with a display screen, i.e., the time when the pen tip part is continuously in contact with the display screen. Then a pen movement recognition processing part 18 decides whether or not the coordinates measured by a pen coordinate measurement processing part 13 changes according to the time measured by the elapsed time measurement processing part 13. Then a menu call processing part 14 calls prepared menu items onto the display screen when judging that the pen is fixed on the display screen for the specific time. For example, when the pen movement recognition processing part 18 judges that the coordinates of the pen tip part is fixed to the same coordinates for the specific time, the starting items of the menu are called onto the display screen and displayed.</p> |
