Abstract

One or more touch input signals can be obtained from a touch sensitive device. A touch event model can be used to determine touch and/or gesture events based on the touch input signals. The touch and gesture events can be associated with touch input signals generated from different regions of a web page displayed on the touch sensitive device. Access can be provided to at least one touch or gesture event through a programming interface.

Claims

1. A method comprising:

obtaining one or more touch input signals from a touch sensitive device;

determining two or more touch events based on the touch input signals, where the touch events are associated with touch input signals associated with two or more regions of a web page displayed on the touch sensitive device; and

providing access to at least one touch event through a programming interface.

2. The method of claim 1, where the touch events are from a group of touch events consisting of a touch start event, a touch move event, a touch end event and a touch cancel event.

3. The method of claim 1, where a sequence of touch events are determined including a start touch event, one or more touch move events and a touch end or touch cancel event.

4. The method of claim 1, where two or more touch events are determined to be a touch gesture.

5. The method of claim 1, where the touch events occur at substantially the same time.

6. The method of claim 1, where the web page regions are associated with nodes in a document object model (DOM) and the nodes are at the same or different hierarchical levels of the DOM.

7. The method of claim 1, where access to the touch events are associated with attributes that can be inserted in documents to define event actions in an application.

8. The method of claim 7, where the application is a browser.

9. The method of claim 7, where the event actions include running JavaScript.

10. The method of claim 7, where the attributes are inserted in one or more HTML tags in an HTML document for generating the web page displayed on the touch sensitive device.

11. The method of claim 1, where each touch event is associated with a single touch input signal.

12. The method of claim 11, where each touch input signal is generated in response to touch input generated by a single finger touching the touch sensitive device.

13. A method, comprising:

obtaining one or more touch input signals from a touch sensitive device;

determining two or more touch events based on the touch input signals, where the touch events are associated with touch input signals associated with two or more regions of a web page displayed on the touch sensitive device; and

sending the two or more touch events to the web page for processing.

14. The method of claim 13, where the touch events are from a group of touch events consisting of a touch start event, a touch move event, a touch end event and a touch cancel event.

15. The method of claim 13, where a sequence of touch events are determined including a start touch event, one or more touch move events and a touch end or touch cancel event.

16. The method of claim 13, where two or more touch events are determined to be a touch gesture.

17. The method of claim 13, where the touch events occur at substantially the same time.

18. The method of claim 13, where the web page regions are associated with nodes in a document object model (DOM) and the nodes are at the same or different hierarchical levels of the DOM.

19. The method of claim 13, where the touch events are associated with attributes that can be inserted in documents to define event actions in an application.

20. A system comprising:

a processor;

a computer-readable medium coupled to the processor and having instructions stored thereon, which, when executed by the processor, causes the processor to perform operations comprising;

obtaining one or more touch input signals from a touch sensitive device;

determining two or more touch events based on the touch input signals, where the touch events are associated with touch input signals associated with two or more regions of a web page displayed on the touch sensitive device; and

providing access to at least one touch event through a programming interface.

21. The system of claim 20, wherein the touch events are from a group of touch events consisting of a touch start event, a touch move event, a touch end event and a touch cancel event.

22. The system of claim 21, wherein a sequence of touch events are determined including a start touch event, one or more touch move events and a touch end or touch cancel event.

23. The system of claim 21, wherein two or more touch events are determined to be a touch gesture.

24. The system of claim 21, where the touch events occur at substantially the same time.

25. A system comprising:

a processor;

a computer-readable medium coupled to the processor and having instructions stored thereon, which, when executed by the processor, causes the processor to perform operations comprising;

obtaining one or more touch input signals from a touch sensitive device;

determining two or more touch events based on the touch input signals, where the touch events are associated with touch input signals associated with two or more regions of a web page displayed on the touch sensitive device; and

sending the two or more touch events to the web page for processing.

26. The system of claim 25, wherein the touch events are from a group of touch events consisting of a touch start event, a touch move event, a touch end event and a touch cancel event.

27. The system of claim 26, wherein a sequence of touch events are determined including a start touch event, one or more touch move events and a touch end or touch cancel event.

28. A system, comprising:

means for obtaining one or more touch input signals from a touch sensitive device;

means for determining two or more touch events based on the touch input signals, where the touch events are associated with touch input signals associated with two or more regions of a web page displayed on the touch sensitive device; and

means for providing access to at least one touch event through a programming interface.

29. A computer-readable medium having instructions stored thereon, which, when executed by a processor, causes the processor to perform operations comprising:

obtaining one or more touch input signals from a touch sensitive device;

determining two or more touch events based on the touch input signals, where the touch events are associated with touch input signals associated with two or more regions of a web page displayed on the touch sensitive device; and

providing access to at least one touch event through a programming interface.
