APPARATUS AND METHOD FOR IDENTIFYING A VALID INPUT SIGNAL IN A TERMINAL
First Claim
1. A terminal, comprising:
- a touch input unit to determine whether a first touch is detected in a display area or a grip recognition area;
a determining unit to determine validity of the first touch based on a location of the detected first touch; and
a processing unit to perform an event corresponding to the first touch when the first touch is determined to be valid.

Abstract
A portable terminal includes a touch input unit to determine whether a first touch is detected in a display area or a grip recognition area, a determining unit to determine validity of the first touch based on a location of the detected first touch, and a processing unit to perform an event corresponding to the first touch when the first touch is determined to be valid. A method for validating a first touch using a processor includes detecting the first touch on a display area or a grip recognition area of a terminal, determining validity of the first touch based on a location of the detected first touch, and performing, using the processor, an event corresponding to the first touch if the first touch is determined to be valid.

12. A method for validating a first touch using a processor, comprising:
-
detecting the first touch on a display area or a grip recognition area of a terminal; determining validity of the first touch based on a location of the detected first touch; and performing, using the processor, an event corresponding to the first touch if the first touch is determined to be valid.
-
-
13. The method of 12, wherein the first touch is determined to be valid if the first touch is detected in the display area and outside of an affect range of the grip recognition area.
-
14. The method of 12, wherein the first touch is determined to be invalid if the first touch is detected in the grip recognition area or within an affect range of the grip recognition area.
-
15. The method of 12, wherein an affect range of the grip recognition area expands into a portion of the display area when a second touch is detected in the display area within a predetermined period of time after the first touch is detected in the grip recognition area.
-
16. The method of 12, wherein the first touch is determined to be valid when a central point of the first touch is determined to be in the display area and outside of an affect range of the grip recognition area.
-
17. The method of 12, wherein the first touch is determined to be invalid if an azimuth of the terminal changes beyond a reference threshold within a predetermined period of time.
-
18. The method of 12, further comprising determining a shape of the first touch, wherein when the shape of the first touch is determined to correspond to a predetermined shape and detected in the display area, the first touch is determined to be valid.
-
19. The method of 12, wherein a second touch in the grip recognition area controls an operation of the terminal.
-
20. A non-transitory computer-readable medium comprising a program, executable by a computer, to perform a method for validating a touch using a processor, the method comprising:
-
detecting the touch on a display area or a grip recognition area of a terminal; determining validity of the touch based on a location of the detected touch; and
performing, using the processor, an event corresponding to the touch when the touch is determined to be valid.
