Title:
CONTROL METHOD, TOUCH PANEL DEVICE, CONTROL PROGRAM, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/009949
Kind Code:
A1
Abstract:
According to the present invention, stress on an operator is reduced. A touch panel control method of the present invention executes a self-capacity information acquisition step, a mutual capacity information acquisition step, and a contact determination step. In the self-capacity information acquisition step, information on the contact with the touch panel is acquired for each X electrode and each Y electrode by a self-capacity method, and a self-change amount corresponding to the change amount of the capacitance is obtained. In the mutual capacity information acquisition step, one among the X electrode and the Y electrode is used as the transmitting-side electrode and the other is used as the receiving side-electrode, information on the contact with the touch panel is acquired for each pair of X and Y electrodes, by a mutual capacity method, and the amount of mutual change corresponding to the amount of change in capacitance is obtained. In the contact determination step, the contact of an indicator with the touch panel and abnormality are detected, on the basis of the self-change amount, the mutual change amount, the first self-threshold value, the second self-threshold value, the first mutual threshold value, and the second mutual threshold value.
