Abstract

An apparatus and method for displaying content is disclosed. A particular method includes determining a viewing orientation of a user relative to a display and providing a portion of content to the display based on the viewing orientation. The portion includes at least a first viewable element of the content and does not include at least one second viewable element of the content. The method also includes determining an updated viewing orientation of the user and updating the portion of the content based on the updated viewing orientation. The updated portion includes at least the second viewable element. A display difference between the portion and the updated portion is non-linearly related to an orientation difference between the viewing orientation and the updated viewing orientation.

8. The method of claim 1, wherein the orientation difference corresponds to a change in a viewer-device relative geometry location.

9. The method of claim 1, wherein the updated viewing orientation is detected based at least in part on a detected gesture of the user.

10. The method of claim 1, wherein orientation difference is determined based at least in part on a measured movement of the device.

11. The method of claim 1, wherein the first portion and the second portion correspond to portions of a cylindrical representation of the plurality of viewable elements that is rendered by the display.

12. The method of claim 11, wherein the display difference corresponds to an amount of rotation of the cylindrical representation about an axis.

13. The method of claim 12, wherein the orientation difference corresponds to an amount of rotation of the device, and wherein the amount of rotation of the device is non-linearly related to the amount of rotation of the cylindrical representation about the axis.

14. The method of claim 13, wherein a rate of the rotation of the cylindrical representation is determined based on the orientation difference.

15. The method of claim 14, wherein the rate of the rotation is represented by a floating point number.

16. An apparatus comprising:

a processor; and

a memory coupled to the processor, the memory including content that includes a plurality of viewable elements, the memory further including instructions that are executable by the processor to;

determine a viewing orientation of a user relative to a display;

provide a first portion of the content to the display based on the viewing orientation, wherein the first portion includes at least a first viewable element of the content and does not include at least one second viewable element of the content;

determine an updated viewing orientation of the user; and

provide an updated portion of the content to the display based on the updated viewing orientation, wherein the updated portion includes at least the second viewable element, wherein a display difference between the first portion and the updated portion is non-linearly related to an orientation difference between the viewing orientation and the updated viewing orientation.

17. The apparatus of claim 16, wherein the display is integral to the apparatus.

18. The apparatus of claim 17, further comprising a camera coupled to the processor.

19. The apparatus of claim 18, wherein the instructions are further executable by the processor to determine a viewing orientation of the user relative to the display based on one or more images captured by the camera.
