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 performed by a device that includes one or more processors and memory storing one or more instructions for execution by the one or more processors, the method comprising:

receiving touch input signals associated with a respective region of a web page, wherein the respective region of the web page is associated with a plurality of event handlers or event listeners including an event handler or listener for a touch event and an event handler or listener for a gesture event; and

in response to receiving the touch input signals;

generating two or more touch events based on the touch input signals;

generating a gesture event by combining the touch events;

sending the gesture event to the web page;

dynamically rotating an element associated with the respective region of the web page with the event handler or listener for the gesture event based on a rotation value associated with the gesture event; and

sending the touch events to the web page for processing, the processing distinct from the dynamically rotating.

2. The method of claim 1, wherein the rotation value is a relative delta in degrees.

13. The method of claim 1, wherein the processing includes moving the element associated with the respective region of the web page.

17. The method of claim 1, wherein the touch events are sent to the web page in a touch list, the touch list including touch event data to identify the touch events, wherein the touch event data includes a touch identifier and at least one set of touch location coordinates, wherein the touch list further includes 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.

3. A method performed by a device that includes one or more processors and memory storing one or more instructions for execution by the one or more processors, the method comprising:

receiving touch input signals associated with a respective region of a web page, wherein the respective region of the web page is associated with a plurality of event handlers or event listeners including an event handler or listener for a touch event and an event handler or listener for a gesture event; and

in response to receiving the touch input signals;

generating two or more touch events based on the touch input signals;

generating a gesture event by combining the touch events;

sending the gesture event to the web page;

dynamically resizing an element associated with the respective region of the web page with the event handler or listener for the gesture event based on a scaling value associated with the gesture event; and

sending the touch events to the web page for processing, the processing distinct from the dynamically resizing.

4. The method of claim 3, wherein the scaling value is a relative delta in document pixels.

14. The method of claim 3, wherein the processing includes moving the element associated with the respective region of the web page.

18. The method of claim 3, wherein the touch events are sent to the web page in a touch list, the touch list including touch event data to identify the touch events, wherein the touch event data includes a touch identifier and at least one set of touch location coordinates, wherein the touch list further includes 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.

5. A method performed by a device that includes one or more processors and memory storing one or more instructions for execution by the one or more processors, the 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 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 non-transitory computer-readable medium having instructions stored thereon, which, when executed by one or more processors of a device, cause the device to perform operations comprising:

receiving touch input signals associated with a respective region of a web page, wherein the respective region of the web page is associated with a plurality of event handlers or event listeners including an event handler or listener for a touch event and an event handler or listener for a gesture event; and

in response to receiving the touch input signals;

generating two or more touch events based on the touch input signals;

generating a gesture event by combining the touch events;

sending the gesture event to the web page;

dynamically rotating an element associated with the respective region of the web page with the event handler or listener for the gesture event based on a rotation value associated with the gesture event; and

sending the touch events to the web page for processing distinct from the dynamically rotating.

8. The computer-readable medium of claim 7, wherein the rotation value is a relative delta in degrees.

15. The computer-readable medium of claim 7, wherein the processing includes moving the element associated with the respective region of the web page.

9. A non-transitory computer-readable medium having instructions stored thereon, which, when executed by one or more processors of a device, cause the device to perform operations comprising:

receiving touch input signals associated with a respective region of a web page, wherein the respective region of the web page is associated with a plurality of event handlers or event listeners including an event handler or listener for a touch event and an event handler or listener for a gesture event; and

in response to receiving the touch input signals;

generating two or more touch events based on the touch input signals;

generating a gesture event by combining the touch events;

sending the gesture event to the web page;

dynamically resizing an element associated with the respective region of the web page with the event handler or listener for the gesture event based on a scaling value associated with the gesture event; and

sending the touch events to the web page for processing distinct from the dynamically resizing.

10. The computer-readable medium of claim 9, wherein the scaling value is a relative delta in document pixels.

16. The computer-readable medium of claim 9, wherein the processing includes moving the element associated with the respective region of the web page.

11. A non-transitory computer-readable medium having instructions stored thereon, which, when executed by one or more processors of a device, cause the device 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 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.
