Abstract

A gesture detecting method for a touch panel is provided. First, a command mode of the touch panel is established based on a hop touch with fingers sequentially touching the touch panel and staying for a while. Then, a gesture is determined according to an eventually detected touch result of a single-point or multipoint touch, i.e., a detected moving track of the touch points, so as to generate and transmit a gesture instruction.

Claims

1. A gesture detecting method for a touch panel, comprising the steps of:

detecting a first click of a first object at a first touch coordinate;

detecting a second click of a second object at a second touch coordinate;

entering a gesture detecting mode, when the first click and the second click are hop clicks and the second object stays at the second touch coordinate for exceeding a period of dwell time after making the second click;

detecting a moving track of the second object within a default time, after detecting the second object leaves the second touch coordinate; and

determining a gesture according to a first number of the first click, a second number of the second click, and the moving track.

2. The method according to claim 1, further comprising the step of:

exiting the gesture detecting mode, when it is detected that the second object stays still at the second touch coordinate for exceeding a period of maximum dwell time after making the second click.

3. The method according to claim 2, wherein the period of maximum dwell time is in a range of 3 to 5 seconds, and the period of dwell time is in a range of 0.1 to 3 seconds.

4. The method according to claim 1, further comprising the steps of:

outputting a gesture instruction according to the gesture;

outputting a coordinate of the second object; and

outputting a gesture detecting mode instruction.

5. The method according to claim 1, wherein the moving track is selected from a group consisting of a first direction track, a first reverse direction track, a counterclockwise rotation track, and a clockwise rotation track, and the first direction and the first reverse direction are two direction dimensions obtained by dividing a two-dimensional space of the touch panel with a mean line.

6. The method according to claim 5, wherein gestures corresponding to the moving tracks comprise:

a gesture of zooming in corresponding to the first direction track;

a gesture of zooming out corresponding to the first reverse direction track;

a gesture of rotating clockwise of a frame corresponding to the clockwise rotation track; and

a gesture of rotating counterclockwise of a frame corresponding to the counterclockwise rotation track.

7. The method according to claim 6, wherein the mean line is a horizontal line, and the first direction track and the first reverse direction track are selected from circumstances such that:

the first direction track is a track having an upward trend, while the first reverse direction track is a track having a downward trend; and

the first direction track is a track having a downward trend, while the first reverse direction track is a track having an upward trend.

8. The method according to claim 6, wherein the mean line is a vertical line, and the first direction track and the first reverse direction track are selected from circumstances such that:

the first direction track is a track having a leftward trend, while the first reverse direction track is a track having a rightward trend; and

the first direction track is a track having a rightward trend, while the first reverse direction track is a track having a leftward trend.

9. The method according to claim 1, wherein gestures corresponding to the moving tracks comprise:

a gesture of dragging up corresponding to an upward track;

a gesture of dragging down corresponding to a downward track;

a gesture of moving forward corresponding to a leftward track;

a gesture of moving back corresponding to a rightward track;

a gesture of delete corresponding to a left-upward track;

a gesture of undoing corresponding to a left-downward track;

a gesture of copying corresponding to a right-upward track;

a gesture of pasting corresponding to a right-downward track;

a gesture of redoing corresponding to a counterclockwise rotation track;

a gesture of undoing corresponding to a clockwise rotation track;

a gesture of checking-off corresponding to a non-isometric checkmark track;

a gesture of inserting corresponding to an isometric checkmark track;

a gesture of inserting corresponding to a triangular track;

a gesture of erasing content corresponding to a back-and-forth moving track;

a gesture of cutting corresponding to a single-helical track;

a gesture of copying corresponding to a double-helical track;

a gesture of pasting and inserting corresponding to an inverted checkmark track;

an application specific gesture corresponding to a circle-drawing track;

a gesture of pasting corresponding to a double-circle-drawing track; and

a gesture of an action item corresponding to a star-shaped track.

10. A gesture detecting method for a touch panel, comprising the steps of:

detecting a first click of a first object at a first touch coordinate;

detecting a second click of a second object at a second touch coordinate;

entering a gesture detecting mode, when the first click and the second click are hop clicks;

detecting a moving track of the second object within a default time, when it is detected that the second object leaves the second touch coordinate; and

determining a gesture according to a first number of the first click, a second number of the second click, and the moving track.

11. The method according to claim 10, wherein the moving track is selected from a group consisting of following tracks, and the gesture corresponding to the moving track is as follows:
