DATA INPUT METHOD USING ANALOG TOUCH PANEL

PROBLEM TO BE SOLVED: To easily discriminate and also indicate plural types of data processing contents via an analog touch panel whose data input function is limited. SOLUTION: The coordinates B is indicated and then canceled in a short time to a touch panel 10 while the 1st coordinates A is pressed and indicated. The coordinate change that is detected in response to the operation of the coordinates B shifts to the coordinates C from the coordinates A with no intervention of any intermediate coordinates and then returns to an initial position A. Thereby, a data processing operation that is previously set is carried out in response to the difference of position relations between both points A and C.
