Abstract

A device with a touch-sensitive surface detects a touch on the touch-sensitive surface, determines that the touch is cancelled, and in accordance with a determination that the touch is cancelled, sends a touch cancel event to at least one of the one or more applications. Also disclosed is a device configured to determine that a respective touch has been cancelled by the device. If the respective touch has been cancelled, the device ignores the respective touch. If the respective touch has not been cancelled, the device processes the respective touch. In addition, a device configured to detect one or more touches and process at least a subset of the touches with at least one application is described. While processing at least a subset of the touches, the device receives a touch cancel event, and, in response to receiving the touch cancel event, ignores the touches.

Claims

1. A method performed at an electronic device with a touch-sensitive surface executing one or more applications, the method comprising:

detecting a touch on the touch-sensitive surface;

determining that the touch is cancelled; and

in accordance with a determination that the touch is cancelled, sending a touch cancel event to at least one of the one or more applications.

2. The method of claim 1, further comprising ignoring the touch.

3. The method of claim 1, further comprising:

tracking the touch prior to sending the touch cancel event; and

stopping tracking the touch subsequent to sending the touch cancel event.

4. The method of claim 1, wherein a respective touch is determined to be cancelled in accordance with a determination that the touch is distinct from predefined touches.

5. The method of claim 1, wherein a respective touch is determined to be cancelled in accordance with a determination that the touch is disrupted.

6. An electronic device, comprising:

a touch-sensitive surface;

one or more processors; and

memory storing one or more programs for execution by the one or more processors, the one or more programs including instructions for;

detecting a touch on the touch-sensitive surface;

determining that the touch is cancelled; and

in accordance with a determination that the touch is cancelled, sending a touch cancel event to at least one of the one or more applications.

7. The device of claim 6, wherein a respective touch is determined to be cancelled in accordance with a determination that the touch is disrupted.

8. A non-transitory computer readable storage medium, storing one or more programs for execution by one or more processors of an electronic device with a touch-sensitive surface, the one or more programs including instructions for:

detecting a touch on the touch-sensitive surface;

determining that the touch is cancelled; and

in accordance with a determination that the touch is cancelled, sending a touch cancel event to at least one of the one or more applications.

9. The computer readable storage medium of claim 8, wherein a respective touch is determined to be cancelled in accordance with a determination that the touch is disrupted.

10. A method performed at an electronic device with a touch-sensitive surface, the method comprising:

while detecting one or more touches on the touch-sensitive surface;

determining that a respective touch has been cancelled by the electronic device;

in accordance with a determination that the respective touch has been cancelled by the electronic device, ignoring the respective touch; and

in accordance with a determination that the respective touch has not been cancelled by the electronic device, processing the respective touch.

11. The method of claim 10, further comprising:

tracking the touch prior to the determination that the respective touch has been cancelled; and

stopping tracking the touch subsequent to the determination that the respective touch has been cancelled.

12. The method of claim 10, wherein a respective touch is determined to be cancelled in accordance with a determination that the touch is distinct from predefined touches.

13. The method of claim 10, wherein a respective touch is determined to be cancelled in accordance with a determination that the touch is disrupted.

14. An electronic device, comprising:

a touch-sensitive surface;

one or more processors; and

memory storing one or more programs for execution by the one or more processors, the one or more programs including instructions for;

while detecting one or more touches on the touch-sensitive surface;

determining that a respective touch has been cancelled by the electronic device;

in accordance with a determination that the respective touch has been cancelled by the electronic device, ignoring the respective touch; and

in accordance with a determination that the respective touch has not been cancelled by the electronic device, processing the respective touch.

15. The device of claim 14, wherein a respective touch is determined to be cancelled in accordance with a determination that the touch is disrupted.

16. A non-transitory computer readable storage medium, storing one or more programs for execution by one or more processors of an electronic device with a touch-sensitive surface, the one or more programs including instructions for:

while detecting one or more touches on the touch-sensitive surface;

determining that a respective touch has been cancelled by the electronic device;

in accordance with a determination that the respective touch has been cancelled by the electronic device, ignoring the respective touch; and

in accordance with a determination that the respective touch has not been cancelled by the electronic device, processing the respective touch.

17. The computer readable storage medium of claim 16, wherein a respective touch is determined to be cancelled in accordance with a determination that the touch is disrupted.

18. A method performed at an electronic device with a touch-sensitive surface executing one or more applications, the method comprising:

detecting one or more touches on the touch-sensitive surface;

processing at least a subset of the one or more touches on the touch-sensitive surface with at least one of the one or more applications;

while processing at least the subset of the one or more touches on the touch-sensitive surface;

receiving a touch cancel event;

in response to receiving the touch cancel event, ignoring the one or more touches on the touch-sensitive surface.

19. The method of claim 18, further comprising:

tracking a respective touch prior to receiving the touch cancel event; and

stopping tracking the respective touch subsequent to receiving the touch cancel event.

20. The method of claim 18, wherein the touch cancel event is generated in accordance with a determination that a respective touch is distinct from predefined touches.

21. The method of claim 18, wherein the touch cancel event is generated in accordance with a determination that a respective touch is disrupted.

22. An electronic device, comprising:

a touch-sensitive surface;

one or more processors; and

memory storing one or more programs for execution by the one or more processors, the one or more programs including instructions for;

detecting one or more touches on the touch-sensitive surface;

processing at least a subset of the one or more touches on the touch-sensitive surface with at least one of the one or more applications;

while processing at least the subset of the one or more touches on the touch-sensitive surface;

receiving a touch cancel event;

in response to receiving the touch cancel event, ignoring the one or more touches on the touch-sensitive surface.

23. The device of claim 22, wherein the touch cancel event is generated in accordance with a determination that a respective touch is disrupted.

24. A non-transitory computer readable storage medium, storing one or more programs for execution by one or more processors of an electronic device with a touch-sensitive surface, the one or more programs including instructions for:

detecting one or more touches on the touch-sensitive surface;

processing at least a subset of the one or more touches on the touch-sensitive surface with at least one of the one or more applications;
