<p>PURPOSE:To speed up a gesture function when the gesture function is effective by providing a means which decides whether or not the gesture function is effective from pen-down coordinates where an input pen abuts on a tablet first at the time of the gesture function. CONSTITUTION:Respective coordinate data of drawing are detected in order by a track coordinate extraction part 21 which is connected to the tablet 19. At this time, the gesture decision part 22 for which the coordinate data from the track coordinate extraction part 21 are inputted decides whether or not the pen-down coordinates as XY coordinates that the input pen 12 abuts on the tablet 19 first among the coordinate data are in the effective area of the gesture function. Further, the gesture decision part 22 once deciding that the pen-down coordinates are effective sets the pen-down coordinates corresponding to each display screen of a display device 14 and decides whether or not the coordinates are in a pen button area where a choice is made with the input pen 12.</p> |
