Abstract

An apparatus includes a touch sensing unit configured to receive a first-type touch input in a first mode, the first-type touch input being not processed in a second mode dedicated for a second-type touch input, and a controller configured to determine whether the first mode is operated, and to process an operation in the first mode according to the first-type touch input. A method for processing a plurality of touch input types includes receiving a touch input, determining a type of the touch input from a plurality of touch input types including a first-type touch input and a second-type touch input, and, in response to a determination that the touch input corresponds to the first-type touch input, processing the touch input if the touch input corresponds to a defined input pattern or the touch input is received in a first mode for processing the first-type touch input.

Claims

1. An apparatus, comprising:

a touch sensing unit configured to receive a first-type touch input in a first mode, the first-type touch input being not processed in a second mode dedicated for a second-type touch input; and

a controller configured to determine whether the first mode is operated, and to process an operation in the first mode according to the first-type touch input.

2. The apparatus of claim 1, wherein the controller is configured to determine a received touch input as the first-type touch input if the received touch input has a value less than a threshold value, and to determine the received touch input as the second-type touch input if the received touch input has a value greater than or equal to the threshold value.

3. The apparatus of claim 2, wherein, in the first mode, the controller is configured to adjust the threshold value in order to enable the operation corresponding to the first-type touch input.

4. The apparatus of claim 3, wherein the threshold value is related to at least one of a value for determining a touch receivable area and a capacitive value generated by a touch input.

5. The apparatus of claim 1, further comprising:

a pattern database to store an input pattern for a first-type touch input capable of being processed in the first mode,

wherein the controller processes the operation if the received first-type touch input corresponds to an input pattern stored in the pattern database.

6. The apparatus of claim 5, wherein the controller determines a first input pattern for the first-type touch input based on a plurality of touch input recognition block, and determines whether the first input pattern corresponds to an input pattern stored in the pattern database.

7. The apparatus of claim 1, wherein the touch sensing unit comprises a first area for receiving the first-type touch input and a second area for receiving the second-type touch input, the second-type touch input being processed in the first mode or the second mode.

8. The apparatus of claim 1, wherein the controller is configured to switch between the first mode and the second mode based on at least one of a mode switching timer expiration, a recognition of a first-type touch input undefined in a pattern database, and a recognition of the second-type touch input.

9. The apparatus of claim 1, wherein the controller is configured to switch from an active state to an idle state according to a state switching timer expiration, and to switch from the idle state to the active state if the second-type touch input being processed in the second mode or an input pattern of the first-type touch input is recognized.

10. An apparatus, comprising:

a touch sensing unit comprising a first area to receive a first touch input, wherein at least a portion of the first area corresponding to an area for gripping the apparatus; and

a controller configured to determine a grip type of the apparatus according to the first touch input, and to provide a user interface based on the determined grip type.

11. The apparatus of claim 10, wherein the controller determines an input pattern for the first touch input, and determines the grip type of the apparatus according to the determined input pattern.

12. The apparatus of claim 10, wherein the grip type comprises a right-hand grip, a left-hand grip, and a two-hand grip.

13. The apparatus of claim 10, wherein the first area is activated to receive and process the first touch input in a first mode and deactivated in a second mode.

14. A method for processing a plurality of types of touch inputs, comprising:

receiving a touch input;

determining a type of the touch input from a plurality of touch input types comprising a first-type touch input and a second-type touch input; and

in response to a determination that the touch input corresponds to the first-type touch input, processing the touch input if the touch input corresponds to a defined input pattern or the touch input is received in a first mode for processing the first-type touch input.

15. The method of claim 14, wherein the first-type touch input corresponds to a noise input having a value less than a threshold value, and a second-type touch input corresponds to a normal input having a value greater than or equal to the threshold value.

16. The method of claim 15, further comprising:

adjusting the threshold value if a mode is switched from or switched to the first mode for processing the first-type touch input.

17. The method of claim 14, wherein the defined input pattern is stored in a pattern database.

18. The method of claim 14, further comprising:

in response to a determination that the touch input corresponds to the second-type touch input, processing the touch input regardless of whether the touch input corresponds to the defined input pattern or the touch input is received in the first mode for processing the first-type touch input.

19. The method of claim 14, further comprising;

switching to a second mode for disabling a processing of the first-type touch input if the touch input corresponds to a second-type touch input or the touch input corresponds to a first-type touch input having an undefined input pattern.

20. The method of claim 14, further comprising;

switching to the first mode for processing the first-type touch input based on at least one of a mode switching timer expiration and a counter setting value.
