<p>PURPOSE:To improve operability by dynamically setting transformation of coordinate system to logically coincide a point, at which a coordinate indicating device is separated from a tablet board, with the point, at which the coordinate indicating device is placed next, in an operation just before the setting of the transformation of the coordinate system is executed. CONSTITUTION:In the operation just before a transformation of coordinate system setting switch 5 is pressed, the transformation of the coordinate system between a tablet board 11 and a display is set, which logically coincides a position, at which a coordinate indicating device 14 is separated from the tablet board 11, with the position, at which the coordinate indicating device 14 is placed after that. The position at which the coordinate indicating device 14 is separated from the tablet board 11 in a previous operation corresponds to the position at which a cursor is displayed last on the display. Therefore, when the transformation of the coordinate system setting switch 5 is pressed, wherever the coordinate indicating device 14 is placed on the tablet board 11, its position corresponds to the position at which the cursor is placed last on the display. Thus, coordinates can be determined accurately and efficiently.</p> |
