Abstract

A device and a method for controlling a touch event in an electronic device are provided. The method include receiving at least one touch event occurring in a touch panel unit; recognizing that a ghost touch has occurred based on time information and coordinate information of the received at least one touch event; and performing at least one of initialization or calibration of the touch panel unit, when recognizing that a ghost touch has occurred.

Claims

1. A method of controlling a touch event in an electronic device, the method comprising:

receiving at least one touch event occurring in a touch panel unit;

recognizing that a ghost touch has occurred based on time information and coordinate information of the received at least one touch event; and

performing at least one of initialization or calibration of the touch panel unit, when recognizing that a ghost touch has occurred.

2. The method of claim 1, wherein the at least one touch event comprises at least one of a touch press, a touch release, and a touch move.

3. The method of claim 1, wherein the initialization comprises re-booting of an Integrated Circuit (IC) included in the touch panel unit.

4. The method of claim 1, wherein recognizing that the ghost touch has occurred comprises recognizing that the ghost touch has occurred based on a number of times in which a touch press and a touch release are repeatedly input, when a repeated input of the touch press and the touch release is detected.

5. The method of claim 1, wherein recognizing that the ghost touch has occurred comprises recognizing that the ghost touch has occurred based on a time in which a touch press is maintained, when a touch release is not detected after the touch press is detected.

6. The method of claim 1, wherein recognizing that the ghost touch has occurred comprises recognizing that the ghost touch has occurred based on a number of times in which a touch move is repeatedly input, when a repeated input of the touch move is detected after a touch press is detected.

7. The method of claim 1, further comprising determining whether coordinate information about the at least one touch event is included in an edge area of the touch panel unit.

8. The method of claim 7, further comprising differently setting a first reference that recognizes that the ghost touch has occurred in a non-edge of the touch panel unit and a second reference that recognizes that the ghost touch has occurred in the edge area of the touch panel unit, when the coordinate information about the at least one touch event is included in the edge area of the touch panel unit.

9. The method of claim 1, wherein recognizing that the ghost touch has occurred comprises recognizing that the ghost touch has occurred in a superordinate stage than that of firmware.

10. An electronic device, comprising:

at least one processor;

at least one memory;

at least one touch panel unit; and

at least one program stored in the at least one memory and to be executed by the at least one processor,

wherein the processor is configured to receive at least one touch event occurring at the touch panel unit, to recognize that a ghost touch has occurred based on time information and coordinate information about the at least one touch event, and to perform at least one of initialization or calibration of the touch panel unit, when recognizing that a ghost touch has occurred.

11. The electronic device of claim 10, wherein the at least one touch event comprises at least one of a touch press, a touch release, and a touch move.

12. The electronic device of claim 10, wherein the initialization comprises re-booting of an Integrated Circuit (IC) included in the touch panel unit

13. The electronic device of claim 10, wherein the processor is configured to recognize that the ghost touch has occurred based on a number of times in which a touch press and a touch release are repeatedly input, when a repeated input of the touch press and the touch release is detected.

14. The electronic device of claim 10, wherein the processor is configured to recognize that the ghost touch has occurred based on a time in which a touch press is maintained, when a touch release is not detected after the touch press is detected.

15. The electronic device of claim 10, wherein the processor is configured to recognize that the ghost touch has occurred based on a number of times in which a touch move is repeatedly input, when a repeated input of the touch move is detected after a touch press is detected.

16. The electronic device of claim 10, wherein the processor is configured to determine whether coordinate information about the at least one touch event is included in an edge area of the touch panel unit.

17. The electronic device of claim 16, wherein the processor is configured to differently set a first reference that recognizes that the ghost touch has occurred in a non-edge area of the touch panel unit and a second reference that recognizes that the ghost touch has occurred in the edge area of the touch panel unit, when the coordinate information corresponding to the at least one touch event is included in the edge area of the touch panel unit.

18. The electronic device of claim 10, wherein the processor is configured to recognize that the ghost touch has occurred in a superordinate stage than that of firmware.
