<p>PROBLEM TO BE SOLVED: To provide a graphic user interface where an operation of a user is facilitated and program generating work is reduced in amt. SOLUTION: An optional coordinate within the area of a screen 202 is inputted by a finger 213b in a left upper input waiting state (b). In a same way, an input is executed by the finger 213c in a right lower input waiting state (c). In a magnifying power input waiting state (d), one of a '2' button, '4' button and a '8' button on a 'magnifying power input' screen 211a is depressed and a prescribed magnifying power is inputted. The optional coordinate within the range of a magnified screen 212 is inputted by the finger 213e in a coordinate input waiting state (e). The position of the coordinate inputted by the finger 213e is calculated with the magnified screen 212 as reference so as to be divided by preserbed magnifying power. By the processings, the position from a left upper part in a rectangular screen 209 before magnification is calculated and is added to the preserved coordinate so as to obtain the coordinate of the original rectangular screen 209 which is inputted by the finger 213e.</p> |
