Abstract

Improved approaches for users to interact with graphical user interfaces of computing devices are disclosed. A rotational user action supplied by a user via a user input device can provide accelerated scrolling. The accelerated nature of the scrolling enables users to scroll or traverse a lengthy data set (e.g., list of items) faster and with greater ease. The amount of acceleration provided can be performed in successive stages, and/or performed based on the speed of the rotational user action. In one embodiment, the rotational user action is transformed into linear action with respect to a graphical user interface. The resulting acceleration effect causes the linear action to be enhanced such that a lengthy data set is able to be rapidly traversed.

Claims

1. A method, comprising:

at a portable electronic device with a display, a rotational input device, and an audio feedback unit;

displaying a list of items with the display;

detecting rotational movement of the rotational input device; and

,

in response to detecting rotational movement of the rotational input device;

scrolling the list of items to an entry in the list, and

outputting, with the audio feedback unit, a sound effect at a particular frequency, wherein the particular frequency is based on a characteristic of the detected rotational movement.

2. The method of claim 1, wherein the entry in the list corresponds to a media item.

3. The method of claim 1, wherein the characteristic of the detected rotational movement is a speed of the detected rotational movement.

4. The method of claim 1, wherein the particular frequency increases as the detected rotational movement increases.

5. The method of claim 1, wherein the particular frequency is proportional to a rate of the detected rotational movement.

6. The method of claim 1, wherein the particular frequency indicates a rate at which the item in the list are being scrolled.

7. The method of claim 1, including:

in response to detecting rotational movement of the rotational input device;

moving a visual indicator to the entry in the list.

8. A portable electronic device, comprising:

a display;

a rotational input device;

an audio feedback unit;

a processor; and

computer readable storage media including instructions configured to be executed by the processor, including instructions for;

displaying a list of items with the display;

detecting rotational movement of the rotational input device; and

,

in response to detecting rotational movement of the rotational input device;

scrolling the list of items to an entry in the list, and

outputting, with the audio feedback unit, a sound effect at a particular frequency, wherein the particular frequency is based on a characteristic of the detected rotational movement.

9. The device of claim 8, wherein the entry in the list corresponds to a media item.

10. The device of claim 8, wherein the characteristic of the detected rotational movement is a sped of the detected rotational movement.

11. The device of claim 8, wherein the particular frequency increases as the detected rotational movement increases.

12. The device of claim 8, wherein the particular frequency is proportional to a rate of the detected rotational movement.

13. The device of claim 8, wherein the particular frequency indicates a rate at which the items in the list are being scrolled.

14. The device of claim 8, including instructions configured to cause the processor to perform operations including:

in response to detecting rotational movement of the rotational input device;

moving a visual indicator to the entry in the list.

15. A computer readable storage media including instructions that when executed by a portable electronic device with a display, a rotational input device, an audio feedback unit, and a processor, cause the portable electronic device to:

display a list of items with the display;

detect rotational movement of the rotational input device; and

,

in response to detecting rotational movement of the rotational input device;

scroll the list of items to an entry in the list, and

output, with the audio feedback unit, a sound effect at a particular frequency, wherein the particular frequency is based on a characteristic of the detected rotational movement.

16. The computer readable storage media of claim 15, wherein the entry in the list corresponds to a media item.

17. The computer readable storage media of claim 15, wherein the characteristic of the detected rotational movement is a speed of the detected rotational movement.

18. The computer readable storage media of claim 15, wherein the particular frequency increases as the detected rotational movement increases.

19. The computer readable storage media of claim 15, wherein the particular frequency is proportional to a rate of the detected rotational movement.

20. The computer readable storage media of claim 15, wherein the particular frequency indicates a rate at which the items in the list are being scrolled.

21. The computer readable storage media of claim 15, including instructions that when executed cause the portable electronic device to:

in response to detecting rotational movement of the rotational input device;

move a visual indicator to the entry in the list.
