Filed: 1994-08-31
Abstract: PURPOSE: To facilitate coordinate input by changing the display position of a cursor corresponding to a coordinate area in accordance with the moving direction of a discriminated coordinate area so as not to superpose it on the coordinate area. CONSTITUTION: When a finger is moved to an upper right part on a display screen, a new cursor coordinate value is calculated from positional information on a touch panel 16 touched with the finger and a cursor which can not be observed because of being hidden under the finger is displayed on the upper light part of the finger. Namely the position data of a coordinate area touched with the finger are read out as the position data of a moved destination and a moving direction value is computed based upon the position data of an unmoved coordinate area and that of the moved destination. Thus the data of a cursor display position are read out from a cursor display position storing area in a memory 22. A cursor coordinate value to be practically displayed is computed based upon the position data of the coordinate area of the moved destination and the data of the cursor display position.  Then the cursor is moved in the upper right direction.
