Abstract

A control method for a touch screen device is provided. The control method comprises the steps of: enabling an active mode of a touch panel; defining at least one active area on the touch panel; inputting a touch input into any one position on the touch panel; determining whether the touch input exists in the active area; and saving calculation of coordinate values of the position corresponding to the touch input and outputting a corresponding predetermined output signal in accordance with the touch input when the touch input exists in the active area.

Claims

1. A control method for a touch screen device, comprising:

enabling an active mode of a touch panel;

defining at least one active area on the touch panel;

inputting a touch input into any one position on the touch panel;

determining whether the touch input exists in the active area; and

saving calculation of coordinate values of the position corresponding to the touch input and outputting a corresponding predetermined output signal in accordance with the touch input when the touch input exists in the active area.

2. The control method of claim 1, wherein the predetermined output signal is directly outputted after an input signal corresponding to the touch input is processed by a firmware.

3. The control method of claim 1, wherein the predetermined output signal is a machine code.

4. The control method of claim 1, wherein the predetermined output signal is a character signal.

5. The control method of claim 4, wherein the character signal is an American Standard Code for Information Interchange (ASCII) code.

6. The control method of claim 1, further comprising:

the touch panel generating no output signal corresponding to the touch input when the touch input exists outside the active area.

7. The control method of claim 1, further comprising:

disabling the active mode, wherein the touch panel generates no output signal corresponding to any touch input when the active mode is disabled.

8. The control method of claim 1, further comprising:

displaying a plurality of active areas on the touch panel under the active mode;

detecting a first touch input and a second touch input performed on the touch panel;

determining whether the first touch input exists in any position of a first active area of the active areas or whether the second touch input exists in any position of a second active area of the active areas; and

when the first touch input exists in the first active area or the second touch input exists in the second active area, saving calculation of coordinate values of the position corresponding to the first or second touch input and outputting a first predetermined output signal corresponding to the first active area in accordance with the first touch input or a second predetermined output signal corresponding to the second active area in accordance with the second touch input.

9. The control method of claim 8, wherein the first or second predetermined output signal is directly outputted after a first input signal corresponding to the first touch input or a second input signal corresponding to the second touch input is processed by a firmware.

10. The control method of claim 8, wherein the first or second predetermined output signal is a machine code.

11. The control method of claim 8, wherein the first or second predetermined output signal is a character signal.

12. The control method of claim 11, wherein the character signal is an American Standard Code for Information Interchange (ASCII) code.

13. The control method of claim 8, further comprising:

when the first touch input exists outside the first active area or the second touch input exists outside the second active area, the touch panel generating no output signal corresponding to the first or second touch input.
