Abstract

A method and apparatus for controlling touch sensitivity in a portable terminal are provided. The method includes controlling the touch sensitivity of a Touch Screen Panel (TSP) according to application or function in operation, and sensing a touch operation generated in the TSP at the controlled touch sensitivity.

Claims

1. A method, operable in a processor, for controlling touch sensitivity in a portable terminal, the method comprising:

controlling the touch sensitivity of a Touch Screen Panel (TSP) according to an application or function in operation in the processor; and

sensing a touch operation generated in the TSP at the controlled touch sensitivity.

2. The method of claim 1, wherein controlling the touch sensitivity according to the application or function in operation comprises:

determining touch sensitivity corresponding to the application or function in operation; and

controlling the touch sensitivity of the TSP to the determined touch sensitivity.

3. The method of claim 1, wherein the touch sensitivity is previously determined as a function of a normal sensitivity, or is determined by a user.

4. An apparatus for controlling touch sensitivity in a portable terminal, the apparatus comprising:

a touch screen panel (TSP) for sensing a touch operation generated by a user at a preset touch sensitivity; and

a TSP control unit for controlling the touch sensitivity of the TSP according to application or function in operation.

5. The apparatus of claim 4, further comprising a baseband unit for informing the TSP control unit of the application or function in operation in the portable terminal.

6. The apparatus of claim 4, wherein the touch sensitivity is previously set or is set by a user.

7. The apparatus of claim 6, wherein the previously set touch sensitivity is determined as a function of a Normal sensitivity.

8. A portable terminal comprising:

a touchscreen; and

a processor in communication with a memory, the memory including code, which when accessed by the processor causes the processor to;

receive an input from the touchscreen;

determine an application executing in the processor;

determine an intensity of the received input;

compare the determined intensity with a sensitivity associated with the determined application executing in the processor; and

accept the input when the determined intensity is comparable to the sensitivity associated with the determined application executing in the processor.

9. The portable terminal of claim 8, further comprising:

a data base including sensitivity levels as a function of applications.

10. The portable terminal of claim 9, wherein the sensitivity levels in the data base on determined based on a function of a normal sensitivity.

11. The portable terminal of claim 9, wherein the sensitivity levels in the data base are manually determined.

12. The portable terminal of claim 8, further comprising:

a mode recognizer for recognizing an application executing in the processor.

13. The portable terminal of claim 12, further comprising:

a sensitivity controller, receiving an input from the mode recognizer, to determine a sensitivity level.
