Abstract

A gesture detecting method for a touch panel is provided. Firstly, a command mode of the touch panel is established based on a hop touch with fingers sequentially touching the touch panel. Then, a gesture is determined according to an eventually detected touch result of a single touch 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:

determining a first touch coordinate of a first object at a first time period;

determining a second touch coordinate of a second object at a second time period;

calculating a first moving speed for moving from the first touch coordinate to the second touch coordinate according to a time difference between the second time period and the first time period;

entering a command mode, when the first moving speed exceeds a default value;

determining a moving track of the second object within a default time period; and

determining a gesture according to the moving track.

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

outputting a gesture instruction according to the gesture.

3. The method according to claim 1, further comprising:

outputting a command mode instruction.

4. The method according to claim 2, further comprising:

outputting a coordinate of the first object.

5. The method according to claim 4, further comprising:

outputting a coordinate of the second object.

6. The method according to claim 1, wherein the step of determining the gesture according to the moving track further comprises the step of:

comparing the moving track with a plurality of default moving tracks stored in a database, so as to determine the gesture.

7. The method according to claim 1, wherein the moving track is selected from a group consisting of:

an upward track, a downward track, a leftward track, a rightward track, a left-upward track, a left-downward track, a right-upward track, a right-downward track, a counterclockwise rotation track, a clockwise rotation track, a non-isometric checkmark track, an isometric checkmark track, a triangular track, a back-and-forth moving track, a single-helical track, and a circle-drawing track.

8. The method according to claim 7, wherein the gesture is selected from a group consisting of:

a gesture of dragging up corresponding to the upward track;

a gesture of dragging down corresponding to the downward track;

a gesture of moving forward corresponding to the leftward track;

a gesture of moving back corresponding to the rightward track;

a gesture of deleting corresponding to the left-upward track;

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

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

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

a gesture of redoing corresponding to the counterclockwise rotation track;

a gesture of undoing corresponding to the clockwise rotation track;

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

a gesture of inserting corresponding to the isometric checkmark track;

a gesture of inserting corresponding to the triangular track;

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

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

an application specific gesture corresponding to the circle-drawing track.

9. The method according to claim 1, wherein the steps of determining the first touch coordinate and the second touch coordinate are performed according to detected currents.

10. The method according to claim 1, wherein the steps of determining the first touch coordinate and the second touch coordinate are performed according to detected voltages.

11. A gesture detecting method for a touch panel, comprising:

determining a plurality of touch coordinates of a plurality of objects at a plurality of time periods sequentially;

calculating a plurality of moving speeds of the objects using the touch coordinates;

entering a command mode, when the moving speeds exceed a default value;

determining a moving track of a third object according to a detected signal within a default time; and

determining a gesture according to the moving track.

12. The method according to claim 11, further comprising:

outputting a gesture instruction according to the gesture.

13. The method according to claim 11, further comprising:

outputting a command mode instruction.

14. The method according to claim 12, further comprising:

outputting a coordinate of a first object.

15. The method according to claim 14, further comprising:

outputting a coordinate of a second object.

16. The method according to claim 11, wherein the step of determining the gesture according to the moving track further comprises the step of:

comparing the moving track with a plurality of default moving tracks stored in a database, so as to determine the gesture.

17. The method according to claim 11, wherein the moving track is selected from a group consisting of:

an upward track, a downward track, a leftward track, a rightward track, a left-upward track, a left-downward track, a right-upward track, a right-downward track, a counterclockwise rotation track, a clockwise rotation track, a non-isometric checkmark track, an isometric checkmark track, a triangular track, a back-and-forth moving track, a single-helical track, and a circle-drawing track.
