Abstract

Embodiments related to the manipulation of lists via a multi-touch display are disclosed. One disclosed embodiment comprises a computing device having a touch-sensitive display, a processor, and memory. The memory comprises code executable by the processor to display a scrollable list of items on the touch-sensitive display, to detect a first touch gesture over the scrollable list of items on the touch-sensitive display, and, in response, to scroll the scrollable list of items on the touch-sensitive display. The memory further comprises code executable by the processor to detect a second, multi-touch gesture over the scrollable list of items on the touch-sensitive display, and in response to adjust a displayed range of the scrollable list of items.

Claims

1. A method of operating a computing device, the computing device comprising a touch-sensitive display, the method comprising:

displaying a scrollable list of items on the touch-sensitive display, the scrollable list of items including a plurality of simultaneously displayed items;

detecting a first touch gesture over the scrollable list of items on the touch-sensitive display, and in response to detecting the first touch gesture over the scrollable list of items, to scroll the scrollable list of items on the touch-sensitive display by changing a position of each of the plurality of simultaneously displayed items; and

detecting a second, multi-touch gesture over the scrollable list of items on the touch-sensitive display, and in response to detecting the second, multi-touch gesture over the scrollable list of items, to adjust a displayed range of the scrollable list of items.

2. The method of claim 1, further comprising scrolling the scrollable list of items on the touch-sensitive display by changing a position of each of the plurality of simultaneously displayed items in a direction of scrolling based on a component of the first touch gesture being along a same direction as the direction of scrolling.

3. The method of claim 2, further comprising scrolling the scrollable list of items in proportion to the component of the first touch gesture along the same direction as the direction of scrolling.

4. The method of claim 1, wherein the second, multi-touch gesture comprises a change in distance between two or more touch inputs.

5. The method of claim 1, further comprising performing the first touch gesture and second, multi-touch gesture in a temporally overlapping manner by changing the component of the first touch gesture along the direction of scrolling while also changing the distance between the two or more touch inputs.

6. The method of claim 5, further comprising adjusting a rate of scrolling caused by the first touch gesture in response to the second, multi-touch gesture.

7. The method of claim 6, wherein the rate of scrolling caused by the first touch gesture is increased in response to a zoom out operation, and the rate of scrolling is decreased in response to a zoom in operation.

8. The method of claim 1, further comprising scrolling the scrollable list of items in an inertial manner after completion of the first touch gesture.

9. The method of claim 1, wherein the first touch gesture comprises two or more inputs.

10. The method of claim 1, further including displaying the scrollable list of items on the touch-sensitive display while omitting display of a scroll bar associated with the scrollable list of items.

11. A computing device, comprising:

a touch-sensitive display;

a processor; and

memory comprising code stored therein that is executable by the processor to;

display a scrollable list of items on the touch-sensitive display, the scrollable list of items including a plurality of simultaneously displayed items spaced apart from one another;

detect a first touch gesture over the scrollable list of items on the touch-sensitive display, and in response to detecting the first touch gesture over the scrollable list of items, scroll the scrollable list of items by changing a position of each of the plurality of simultaneously displayed items; and

detect a second, multi-touch gesture over the scrollable list of items on the touch-sensitive display, and in response to detecting the second, multi-touch gesture over the scrollable list of items, adjust a displayed range of the scrollable list of items.

12. The computing device of claim 11, wherein the computing device is configured to scroll the scrollable list of items on the touch-sensitive display in a direction of scrolling based on a component of the first touch gesture being along a same direction as the direction of scrolling.

13. The computing device of claim 11, further including code executable to adjust the displayed range of the scrollable list of items based on the second, multi-touch gesture by changing a distance between the two or more touch inputs.

14. The computing device of claim 11, wherein the instructions are executable to detect the first touch gesture and the second, multi-touch gesture when performed in a temporally overlapping manner, and to adjust a rate of scrolling caused by the first touch gesture in response to the second, multi-touch gesture.

15. The computing device of claim 11, wherein the computing device is configured to scroll the scrollable list of items in an inertial manner after completion of the first touch gesture.

16. A computing device, comprising:

a touch-sensitive display;

a processor; and

memory comprising code stored thereon executable by the processor to;

display a scrollable list of items in a graphical user interface on the touch-sensitive display, the scrollable list of items including a plurality of simultaneously displayed items, the simultaneously displayed items spaced apart from one another and each item of the scrollable list of items being selected from the group consisting of an icon, text, and an image;

detect a first touch gesture over the scrollable list of items on the touch-sensitive display in the graphical user interface, and in response to detecting the first touch gesture over the scrollable list of items, scroll the scrollable list of items in the graphical user interface on the touch-sensitive display by changing a position of each of the plurality of simultaneously displayed items in the graphical user interface; and

detect a second, multi-touch gesture over the scrollable list of items on the touch-sensitive display, and in response to detecting the second, multi-touch gesture over the scrollable list of items, adjust a displayed range of the scrollable list of items in the graphical user interface.

17. The computing device of claim 16, wherein the code comprises instructions executable to detect a motion of the first touch gesture on the touch-sensitive display in the graphical user interface along a path within a first range of directions in a scrolling direction, and a motion of the second, multi-touch gesture in a second range of directions transverse to the scrolling direction.

18. The computing device of claim 17, wherein the code further comprises instructions executable to detect a first range of directions and a second range of directions that overlap, and to detect a motion of one or more touch inputs that extend outside of a range of directions.

19. The computing device of claim 18, wherein the code comprises instructions executable to detect a first touch gesture and a second, multi-touch gesture performed in a temporally overlapping manner, and the computing device is configured to adjust a rate of scrolling caused by the first touch gesture in response to the second, multi-touch gesture.

20. The computing device of claim 16, wherein the code comprises instructions executable to revert the displayed range of the scrollable list of items in the graphical user interface to a default value upon completion of the second, multi-touch gesture.
