Abstract
A touch panel electrical device includes a touch panel, a notice signal generator and a processing unit. The processing unit is electrically connected with the touch panel and the notice signal generator respectively. The touch panel senses a touched position on the touch panel. The processing unit includes a notice-generating module. The notice-generating module makes the notice signal generator generate a notice sound signal or a notice vibration signal according to the touched position to notice a user a touched instruction corresponding to the touched position he/she touches.
Claims19
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.
A method for operating a touch panel electrical device, wherein the touch panel electrical device comprises a touch panel, the method for operating the touch panel electrical device comprises:
- sensing a touched position on the touch panel;
- generating a notice sound signal or a notice vibration signal according to the touched position to notice a user a touched instruction corresponding to the touched position he/she touches;
- determining if execute the touched instruction or not, wherein the step of determining if execute the touched instruction or not comprises:
- determining if the touched position is pressed, wherein the touched instruction is determined to be executed if the touched position is determined pressed, wherein the step of determining if the touched position is pressed comprises:
- sensing a present touched area around the touched position on the touch panel;
- calculating a touched area variation between the present touched area and a previous touched area;
- and
- determining if the touched area variation is more than a pressed area variation threshold, wherein the touched position is determined pressed if the touched area variation is more than the pressed area variation threshold;
- and
- if the touched instruction is determined to be executed, making the touch panel electrical device execute the touched instruction.
A method for operating a touch panel electrical device according to touched area, wherein the touch panel electrical device comprises a touch panel, the method for operating the touch panel electrical device according to touched area comprises:
- sensing a touched position on the touch panel;
- determining if execute a touched instruction corresponding to the touched position or not according to a present touched area around the touched position on the touch panel, wherein the step of determining if execute the touched instruction or not comprises:
- determining it the touched position is pressed, wherein the touched instruction is determined to be executed if the touched position is determined pressed, wherein the step of determining if the touched position is pressed comprises:
- sensing a present touched area around the touched position on the touch panel;
- calculating a touched area variation between the present touched area and a previous touched area;
- and
- determining if the touched area variation is more than a pressed area variation threshold, wherein the touched position is determined pressed if the touched area variation is more than the pressed area variation threshold;
- and
- if the touched instruction is determined to be executed, making the touch panel electrical device execute the touched instruction.
