Abstract

There is provided a method for preventing accidentally triggering edge swipe gestures adapted to a touch control system including a touch surface. The method includes the steps of: recording first information when a first gesture is detected to end at a periphery of the touch surface; recording second information when a second gesture is detected to start at the periphery of the touch surface; and determining, by a processor, whether to trigger an edge swipe gesture of the touch control system according to the first information and the second information.

Claims

1. A method for preventing accidentally triggering edge swipe gestures, adapted to a touch control system comprising a touch surface, the method comprising:

recording first information when a first gesture is detected to end at a periphery of the touch surface;

recording second information when a second gesture is detected to start at the periphery of the touch surface; and

determining, by a processor, whether to trigger an edge swipe gesture of the touch control system according to the first information and the second information.

2. The method as claimed in claim 1, wherein the first information comprises a first time and the second information comprises a second time, and the processor determines whether to trigger the edge swipe gesture according to a time difference between the first time and the second time.

3. The method as claimed in claim 2, further comprising:

not triggering the edge swipe gesture when the time difference is smaller than a time threshold; and

triggering the edge swipe gesture when the time difference exceeds the time threshold.

4. The method as claimed in claim 2. wherein the first information further comprises a first position and the second information further comprises a second position, and the processor determines whether to trigger the edge swipe gesture according to the time difference and a distance between the first position and the second position.

5. The method as claimed in claim 4, further comprising:

not triggering the edge swipe gesture when the time difference is smaller than a time threshold and the distance is smaller than a distance threshold; and

triggering the edge swipe gesture when the time difference exceeds the time threshold or the distance exceeds the distance threshold.

6. The method as claimed in claim 4, wherein the periphery comprises at least two edges, and the distance is a pixel distance between positions at an identical edge or at two adjacent edges.

7. A triggering method by gestures, adapted to a window system comprising an operation area, the triggering method comprising:

detecting a first gesture in contact with a periphery of the operation area;

detecting whether there is a second gesture in contact with the periphery within a predetermined time after the first gesture leaves the operation area from the periphery; and

generating a first control command corresponding to the first gesture when the second gesture is not detected within the predetermined time.

8. The triggering method as claimed in claim 7, wherein the first control command is configured to activate an operation or a movement corresponding to the first gesture.

9. The triggering method as claimed in claim 7, further comprising:

combining the first gesture with the second gesture to generate a combined control command when the second gesture is detected within the predetermined time.

10. The triggering method as claimed in claim 9, wherein the combined control command is configured to activate an operation or a movement corresponding to the first gesture combined with the second gesture.

11. The triggering method as claimed in claim 7, further comprising:

recording a first position where the first gesture leaves the periphery; and

recording a second position where the second gesture enters the periphery when the second gesture is detected within the predetermined time.

12. The triggering method as claimed in claim 11, further comprising:

successively generating the first control command corresponding to the first gesture and a second control command corresponding to the second gesture when a distance between the first position and the second position exceeds a distance threshold; and

combining the first gesture with the second gesture to generate a combined control command when the distance between the first position and the second position is smaller than the distance threshold.

13. The triggering method as claimed in claim 7, wherein the operation area is a cursor operation area or a touch operation area of the window system.

14. A triggering method by gestures, adapted to a window system comprising an operation area, the triggering method comprising:

detecting an edge swipe gesture in contact with a periphery of the operation area; and

generating an edge swipe control command when there is no gesture in contact with the periphery within a predetermined time before the edge swipe gesture contacts the periphery.

15. The triggering method as claimed in claim 14, further comprising:

outputting a displacement signal according to the edge swipe gesture but not generating the edge swipe control command when another gesture in contact with the periphery is detected within the predetermined time.

16. The triggering method as claimed in claim 14, further comprising:

combining the edge swipe gesture with a previous gesture to form a continuous gesture but not generating the edge swipe control command when the previous gesture in contact with the periphery is detected within the predetermined time.

17. The triggering method as claimed in claim 14, further comprising:

calculating a distance between a first position of the edge swipe gesture corresponding to the periphery and a second position of a previous gesture corresponding to the periphery when the previous gesture in contact with the periphery is detected within the predetermined time.

18. The triggering method as claimed in claim 17, further comprising:

generating the edge swipe control command when the distance exceeds a distance threshold; and

combining the edge swipe gesture with the previous gesture to form a continuous gesture but not generating the edge swipe control command when the distance is smaller than the distance threshold.

19. The triggering method as claimed in claim 14, wherein the edge swipe gesture is a gesture entering the operation area through the periphery or a gesture swiping at the periphery.

20. The triggering method as claimed in claim 14, wherein the operation area is a cursor operation area or a touch operation area of the window system.
