<p>PURPOSE:To facilitate the operation by catching all screens as the whole assembly of coordinate points, dividing this screen into plural partial image areas, and showing on which partial assembly of coordinate points a moving cursor is overlapped by changing the cursor to a specific shape. CONSTITUTION:To a central processing unit(CPU) 1, a display device 3, a loudspeaker 4, a screen file 6, an individuality file 7, and a mark tide 8 are connected. In such a way, the screen of the display device 3 is caught as the whole assembly of coordinate points, this screen is divided into plural partial image areas at every image of a tree and a mountain, etc., in a picture, and a partial assembly of coordinate points corresponding to these partial image areas, respectively is defined in advance. When a cursor K moves, it comes to overlap the partial assembly of one coordinate point. Therefore, the partial assembly of the coordinate point overlapped by the cursor K is detected, and a mark of a shape for indicating clearly a partial image area corresponding to the partial assembly of this coordinate point is displayed instead of the cursor. In such a way, whether the cursor catches a target partial image or not can be known easily.</p> |
