Abstract

One or more touch input signals can be obtained from a touch sensitive device. If the touch input signals are associated with one or more regions of a web page displayed on the touch sensitive device, a touch event associated with the regions of a web page is processed by the web page. Otherwise, the touch events can be processed by an application (e.g., a browser).

Claims

1. A method, comprising:

at a multi-touch capable device including one or more processors and memory storing a web page that includes instructions for processing one or more touch events and one or more gesture events;

receiving touch input signals associated with multiple concurrent finger touches on one or more elements of the web page displayed on a touch sensitive device;

processing the touch input signals to determine if the touch input signals are associated with a touch gesture made with respect to one or more elements of the web page; and

if the touch input signals are associated with a touch gesture, forwarding a gesture event to the web page for further processing by executing the instructions stored in the web page.

2. The method of claim 1, further comprising:

if the touch input signals are not associated with a touch gesture, processing the touch input signals with an application associated with the touch sensitive device.

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

4. The method of claim 1, where the gesture event comprises two or more touch events.

5. The method of claim 2, where the application is a browser.

6. The method of claim 1, where the gesture event is associated with attributes that can be inserted in documents to define event actions in the web page.

7. The method of claim 6, where the attributes are inserted in one or more HyperText Markup Language (“

HTML”

) tags in an HTML document for generating the web page displayed on the touch sensitive device.

8. The method of claim 7, where processing the gesture event associated with the one or more elements of the web page comprises:

processing the gesture event based on the HTML tag associated with the one or more elements of the web page.

9. The method of claim 1, where the gesture includes a sequence of touch events that include a touch start event, one or more touch move events and a touch end or touch cancel event.

10. The method of claim 1, where the gesture event includes at least two or more touch events that occur at substantially the same time.

11. A system comprising:

a processor; and

a computer-readable medium coupled to the processor, storing a web page that includes instructions for processing one or more touch events and one or more gesture events, and having instructions stored thereon, which, when executed by the processor, cause the processor to perform operations comprising;

receiving touch input signals associated with multiple concurrent finger touches on one or more elements of the web page displayed on a touch sensitive device;

processing the touch input signals to determine if the touch input signals are associated with a touch gesture made with respect to one or more elements of the web page; and

if the touch input signals are associated with a touch gesture, forwarding a gesture event to the web page for further processing by executing the instructions stored in the web page.

12. The system of claim 11, wherein the operations include:

if the touch input signals are not associated with a touch gesture, processing the touch input signals with an application associated with the touch sensitive device.

13. The system of claim 11, where the one or more elements of the web page are associated with one or more nodes in a document object model (DOM) and the nodes are at the same or different hierarchical levels of the DOM.

14. The system of claim 11, where the gesture event comprises two or more touch events.

15. The system of claim 12, where the application is a browser.

16. The system of claim 11, where the gesture event is associated with attributes that can be inserted in documents to define event actions in the web page.

17. The system of claim 16, where the attributes are inserted in one or more HyperText Markup Language (“

HTML”

) tags in an HTML document for generating the web page displayed on the touch sensitive device.

18. The system of claim 17, wherein the operations include:

processing the gesture event based on the HTML tag associated with the one or more elements of a web page.

19. The system of claim 11, where the gesture includes a sequence of touch events that include a touch start event, one or more touch move events and a touch end or touch cancel event.

20. The system of claim 11, where the gesture event includes at least two or more touch events that occur at substantially the same time.

21. A non-transitory computer-readable medium having instructions stored thereon, which, when executed by at least one processor, causes the processor to perform operations comprising:

receiving touch input signals associated with multiple concurrent finger touches on one or more elements of a web page displayed on a touch sensitive device, the web page including instructions for processing one or more touch events and one or more gesture events;

processing the touch input signals to determine if the touch input signals are associated with a touch gesture made with respect to the one or more elements of the web page; and

if the touch input signals are associated with a touch gesture, forwarding a gesture event to the web page for further processing by executing instructions stored in the web page.

22. The non-transitory computer-readable medium of claim 21, wherein the operations include:

if the touch input signals are not associated with a touch gesture, processing the touch input signals with an application associated with the touch sensitive device.
