Abstract

A method for setting and a method for detecting a virtual key of a touch panel are provided. The method for setting the virtual key of the touch panel includes the following steps. A setting interface is provided. A key function is received via the setting interface by a processor. A key area is received via the setting interface by the processor. The key function and the key area are stored in a register. The register corresponds to the virtual key.

Claims

1. A method for setting a virtual key of a touch panel, comprising:

providing a setting interface;

receiving a key function via the setting interface by a processor;

receiving a key area via the setting interface by the processor; and

storing the key function and the key area to a register, the register corresponding to the virtual key.

2. The method according to claim 1, wherein in the step of receiving the key area, the key area comprises a position information.

3. The method according to claim 2, wherein in the step of receiving the key area, the key area comprises a shape information.

4. The method according to claim 3, wherein the step of receiving the key area comprises:

providing at least one basic graphic;

detecting whether the basic graphic is dragged by the processor;

recording a shape of the dragged basic graphic to the shape information by the processor; and

recording a stop position of the dragged basic graphic to the position information by the processor.

5. The method according to claim 4, wherein the setting information comprises a graphic region and a graphic selecting region, the basic graphic is displayed in the graphic selecting region, the basic graphic is dragged to the graphic region, and a coordinate system of the graphic region is directly proportional to that of the touch panel.

6. The method according to claim 5, wherein the setting interface further comprises a position display region for displaying the position information.

7. The method according to claim 6, wherein the setting interface further comprises a function input region for inputting the key function.

8. A method for detecting a virtual key of a touch panel, comprising:

providing a virtual key, the virtual key comprising a key function and a key area and being hidden under a foreground image;

determining by a detector whether the touch panel is pressed;

if the touch panel is pressed, determining whether a pressed position of the touch panel is located in the key area by a processor; and

if the pressed position of the touch panel is located in the key area, performing the key function by the processor when the key area is pressed or released.

9. The method according to claim 8, wherein the key area comprises a position information.

10. The method according to claim 8, wherein the key area comprises a shape information.
