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. In a web browser, a method comprising:

receiving a rotation value associated with a gesture event; and

dynamically rotating an element of a web page associated with the gesture event in the web browser based on the rotation value, wherein the rotation value is a relative delta in degrees.

2. The method of claim 1, wherein the gesture event includes two or more touch events.

8. The computer-readable medium of claim 1, wherein the gesture event includes two or more touch events.

3. In a web browser, a method comprising:

receiving a scaling value associated with a gesture event;

dynamically resizing an element of a web page associated with the gesture event in the web browser based on the scaling value, wherein the scaling value is a relative delta in document pixels.

4. The method of claim 3, wherein the gesture event is associated with two or more touch events.

10. The computer-readable medium of claim 3, wherein the gesture event is associated with two or more touch events.

5. In a web browser, a method comprising:

receiving a touch list, the touch list including touch event data to identify one or more touches on a web page, wherein the touch event data includes a touch identifier and at least one set of touch location coordinates, wherein the touch list further includes touch event data to a touch event target associated with each touch, wherein the at least one set of touch location coordinates includes at least one of client coordinates, page coordinates, and screen coordinates.

6. The method of claim 5, wherein the touch event data identifies one or more changed touches.

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

receiving a rotation value associated with a gesture event associated with a web page; and

dynamically rotating an element of a web page associated with the gesture event in the web browser based on the rotation value, wherein the rotation value is a relative delta in degrees.

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

receiving a scaling value associated with a gesture event associated with a web page;

dynamically resizing an element of a web page associated with the gesture event in the web browser based on the scaling value, wherein the scaling value is a relative delta in document pixels.

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

receiving a touch list, the touch list including touch event data to identify one or more touches on a web page, wherein the touch event data includes a touch identifier and at least one set of touch location coordinates, wherein the touch list further includes touch event data to a touch event target associated with each touch, wherein the at least one set of touch location coordinates includes at least one of client coordinates, page coordinates, and screen coordinates.

12. The computer-readable medium of claim 11, wherein the touch event data identifies one or more changed touches.
