Patent ID: 8659566

Claim:
A touch sensing method, adapted for an electronic apparatus comprising a touch panel, the touch sensing method comprising: driving the touch panel by a mutual capacitance mode and a self capacitance mode; sensing a gesture applied on the touch panel, wherein the gesture forms at least one touch area on the touch panel; if the at least one touch area is larger than a threshold area, determining at least one geometric center of the at least one touch area based on a self-mode data obtained in the self capacitance mode, wherein if the at least one touch area is larger than the threshold area, a hollow effect occurs; and determining at least one touch location associated with the gesture on the touch panel based on the at least one geometric center of the at least one touch area, wherein the self-mode data and the mutual-mode data are obtained under different sensing modes, and one of the self-mode data and the mutual-mode data is not generated from another one of the self-mode data and the mutual-mode data.
