Abstract

Aspects of the present invention provide a system and method for scrolling or dragging information on a display. A panning tool is provided that may scroll information, such as a web page, on a display in tandem with movement of a cursor. If interactive elements are present on the page or document, an interactive element may be activated as desired. Scrolling may be accomplished with the panning tool either on non-interactive elements or interactive elements that are not required to be activated. Furthermore, inertia of movement of the information on a display is optimized and autoscrolling is provided in which a page or document may be scrolled without dragging.

Claims

1. A method comprising:

displaying information in a display area on a display screen of a computing device;

moving the information in response to detecting a drag within proximity to the information by a touch-sensitive surface of the display screen; and

continuing a movement of the information for a particular amount of time after the drag is no longer detected by the touch-sensitive surface.

2. The method of claim 1, wherein the information includes a web page.

3. The method of claim 1, wherein the particular amount of time is based on movement information associated with the drag.

4. The method of claim 1, wherein the particular amount of time is based on a predetermined period of time regardless of movement information associated with the drag.

5. The method of claim 1, wherein a direction of the movement is in a horizontal direction when the drag has both a horizontal component and a vertical component and the vertical component is within a horizontal-tolerance range.

6. The method of claim 1, wherein the movement of the information in the display area is stopped before reaching the particular amount of time in response to another input detected by the touch-sensitive surface.

7. The method of claim 1, wherein the drag detected by the touch-sensitive surface includes detected movement of a user'"'"'s finger in contact with the touch-sensitive surface.

8. One or more computer readable storage media comprising computer-readable instructions that, when executed by a computing device, cause the computing device to perform operations comprising:

displaying information in a display area on a display device of the computing device;

detecting a drag over the information by a touch-sensitive surface of the display device;

scrolling the information in response to the drag; and

continuing the scrolling of the information for a particular amount of time after the drag ends.

9. The one or more computer readable storage media of claim 8, wherein the information includes a web page.

10. The one or more computer readable storage media of claim 8, wherein the particular amount of time depends on one or more characteristics of the drag.

11. The one or more computer readable storage media of claim 10, wherein the one or more characteristics of the drag include one or more of speed, duration, acceleration, or distance of the drag.

12. The one or more computer readable storage media of claim 8, wherein the particular amount of time is based on a predetermined period of time regardless of characteristics of the drag.

13. The one or more computer readable storage media of claim 8, wherein the scrolling of the information in the display area is stopped before reaching the particular amount of time in response to another input detected by the touch-sensitive surface.

14. The one or more computer readable storage media of claim 8, wherein the scrolling decelerates over the particular amount of time.

15. The one or more computer readable storage media of claim 8, wherein detecting the drag includes detecting movement of a user'"'"'s finger in contact with the touch-sensitive surface.

16. A computing device, comprising:

a display device having a touch-sensitive surface;

one or more processing units; and

one or more computer readable storage media comprising computer-readable instructions that when executed by the one or more processing units perform operations comprising;

displaying a web page in a display area of the display device;

scrolling the web page in response to a drag over the displayed web page detected by the touch-sensitive surface;

determining drag information associated with the drag detected by the touch-sensitive surface; and

continuing the scrolling of the web page for a particular amount of time after the drag ends, wherein the particular amount of time depends on the drag information.

17. The computing device of claim 16, wherein the drag information includes one or more of speed, duration, acceleration, or distance of the drag movement.

18. The computing device of claim 16, wherein the scrolling decelerates over the particular amount of time.

19. The computing device of claim 16, wherein the scrolling of the web page in the display area is stopped before reaching the particular amount of time in response to another input detected by touch-sensitive surface.

20. The computing device of claim 16, wherein the drag detected by the touch-sensitive surface includes detected movement of a user'"'"'s finger in contact with the touch-sensitive surface.
