Patent ID: 8508500

Claim:
A touch panel electrical device, comprising: a touch panel, sensing a touched position on the touch panel; a notice signal generator; and a processing unit, electrically connected with the touch panel and the notice signal generator, comprising: a notice-generating module, making the notice signal generator generate a notice sound signal or a notice vibration signal according to the touched position to notice a user of a touched instruction corresponding to the touched position he/she touches; an executing module, executing the touched instruction if the touched position has been continually touched and a confirm signal is received; a confirm module, generating the confirm signal when the touched position or a confirm button of the touch panel electrical device is pressed, wherein the confirm button is electrically connected with the processing unit; and an area-sensing module, sensing a present touched area around the touched position on the touch panel, wherein the confirm module of the processing unit calculates a touched area variation between the present touched area and a previous touched area, and the touched position is determined pressed if the touched area variation is more than a pressed area variation threshold, wherein a touched pixel number of the touch panel around the touched position is sensed to calculate the present touched area.
