Abstract

When operating a resistive touch panel, a first command is issued by touching the touch panel using a finger. When the finger remains in contact with the touch panel, a second command is issued by touching the touch panel using a stylus. Therefore, a corresponding gesture operation can be executed in multi-touch applications after identifying the first and second commands.

Claims

1. A multi-touch method comprising:

issuing a first command by touching a touch panel using a first input device;

issuing a second command by touching the touch panel using a second input device while the first input device is in contact with the touch panel; and

identifying the first and second commands for executing a corresponding gesture operation.

2. The method of claim 1, wherein the gesture operation is associated with motions, taps, selections or data inputs.

3. The method of claim 2, wherein the motions include sliding, deleting, rotating, shaping, enlarging or shrinking.

4. The method of claim 2, wherein the taps include multiple tap, quick tap or slow tap.

5. The method of claim 2, wherein the selections include selecting a specific region on the touch panel or selecting an object shown on the touch panel.

6. The method of claim 1, wherein the gesture operation comprises:

selecting an object shown on the touch panel according to the first command; and

enlarging or shrinking the object according to the second command.

7. The method of claim 1, wherein the gesture operation comprises:

selecting an object shown on the touch panel according to the first command; and

rotating the object according to the second command.

8. The method of claim 1, wherein the gesture operation comprises:

selecting an object shown on the touch panel according to the first command; and

shaping the object according to the second command.

9. The method of claim 1, wherein the gesture operation comprises:

moving an object shown on the touch panel according to the first and second commands.

10. The method of claim 1, wherein the gesture operation comprises:

selecting all objects shown within a specific region on the touch panel according to the first and second commands.

11. The method of claim 1, wherein the gesture operation comprises:

selecting an object shown on the touch panel according to the first command; and

inputting a message on the object according to the second command.

12. The method of claim 1, wherein the gesture operation comprises:

inputting a message on the touch panel according to the second command; and

deleting the message shown on the touch panel according to the first command.

13. The method of claim 1, wherein the gesture operation comprises:

selecting an object shown on the touch panel according to the first command; and

selecting a content of the object according to the second command.

14. The method of claim 1, wherein the first command is issued by touching a first contact point on the touch panel using the first input device, and the second command is issued by touching a second contact point on the touch panel using the second input device.

15. The method of claim 14, wherein the first contact point has a larger area than the second contact point.

16. The method of claim 1, wherein the first command is issued by touching a plurality of first contact points on the touch panel using the first input device, and the second command is issued by touching a plurality of second contact points on the touch panel using the second input device.

17. The method of claim 16, wherein each first contact point has a larger area than each second contact point.

18. The method of claim 1, wherein the first input device is a finger, and the second input device is a stylus.

19. The method of claim 1, wherein the first and second input device are styli.

20. The method of claim 1, wherein the touch panel is a resistive touch panel.

21. A multi-touch method comprising:

issuing a first command by touching a touch panel using a first mechanical device;

issuing a second command by touching the touch panel using a second mechanical device; and

identifying the first and second commands for executing a corresponding gesture operation.

22. The method of claim 21, wherein the gesture operation is associated with motions, taps, selections or data inputs.

23. The method of claim 22, wherein the motions include sliding, deleting, rotating, shaping, enlarging or shrinking.

24. The method of claim 22, wherein the taps include multiple tap, quick tap or slow tap.

25. The method of claim 22, wherein the selections include selecting a specific region on the touch panel or selecting an object shown on the touch panel.

26. The method of claim 21, wherein the gesture operation comprises:

selecting an object shown on the touch panel according to the first command; and

enlarging or shrinking the object according to the second command.

27. The method of claim 21, wherein the gesture operation comprises:

selecting an object shown on the touch panel according to the first command; and

rotating the object according to the second command.

28. The method of claim 21, wherein the gesture operation comprises:

selecting an object shown on the touch panel according to the first command; and

shaping the object according to the second command.

29. The method of claim 21, wherein the gesture operation comprises:

moving an object shown on the touch panel according to the first and second commands.

30. The method of claim 21, wherein the gesture operation comprises:

selecting all objects shown within a specific region on the touch panel according to the first and second commands.

31. The method of claim 21, wherein the gesture operation comprises:

selecting an object shown on the touch panel according to the first command; and

inputting a message on the object according to the second command.

32. The method of claim 21, wherein the first command is issued by touching a first contact point on the touch panel using the first mechanical device, and the second command is issued by touching a second contact point on the touch panel using the second mechanical device.

33. The method of claim 21, wherein the first and second mechanical devices are styli.

34. The method of claim 21, wherein the touch panel is a resistive touch panel.
