Abstract

A method of presenting content on the user interface display screen of a portable electronic device includes the presentation of a plurality of icons. The icons scale in size in accordance with a position of the respective icons along a curved path.

Claims

1. A user interface configured for selection of media content items, the user interface comprising:

a touch sensitive display screen having visible a plurality of icons representing items that may be selected by a user, wherein said icons are distributed along a curved path and have corresponding sizes that depends upon their positions on the curved path; and

a user input sensing mechanism configured to cause said icons to move along said curved path in at least one of a forward and reverse direction in response to a sensed user input direction, wherein each of the plurality of icons moves to an adjacent position along said curved path by a distance that varies in proportion to its size such that small sized icons move small distances and larger sized icons move larger distances.

2. The user interface as recited in claim 1 wherein the sensed user input direction is provided by a pointing device in contact with the display screen.

3. The user interface as recited in claim 2 wherein the pointing device is a finger.

4. The user interface as recited in claim 2 wherein the user interface is further configured to cause said icons to continue to move and gradually come to a halt after said pointing device has been removed from said screen.

5. The user interface as recited in claim 1 wherein the plurality of icons are configured to change resolution to correspond to their changed size along the curved path.

6. The user interface as recited in claim 1 wherein the curved path is an ellipse.

7. The user interface as recited in claim 1 wherein the user interface is configured such that the icons have an area approaching zero as the respective icon position approaches an endpoint of the curved path on the display screen.

8. The user interface as recited in claim 1, wherein only icons including and not exceeding a selected threshold of size are user non-selectable.

9. The user interface as recited in claim 1, wherein the plurality of icons move at equal time intervals between sequential positions along said curved path.

10. The user interface as recited in claim 1, wherein each of the plurality of icons is parallel to said curved path.

11. The user interface as recited in claim 1, wherein a degree of curvature of the curved path is dynamically adjusted to increase when the plurality of icons'"'"' movement increases in speed along said curved path.

12. A method of selecting content on a display screen of a portable media player, the method comprising:

representing a plurality of content items by a plurality of icons having corresponding sizes positioned along a curved path in the display screen; and

varying the respective sizes of the icons as a function of the location of the icons relative to a predetermined position;

wherein the display screen is configured to cause the icons to travel along the curved path in response to a user input, and wherein each of the plurality of icons travels to the adjacent predetermined position along the curved path by a distance that varies in proportion to its size such that small sized icons move small distances and larger sized icons move larger distances.

13. The method as recited in claim 12 wherein the display screen is a touch screen and the icons are selectable by touching the display screen.

14. The method as recited in claim 13 wherein the predetermined position is a point located between the endpoints of the curved path but not at the endpoints and wherein the icon at the predetermined position is the largest icon of the plurality.

15. The method as recited in claim 12 wherein the curved path simulates part of an ellipse.

16. The method as recited in claim 12 wherein the plurality of icons are caused to move along a curved path that simulates one of a circular or elliptical path in a three dimensional view and wherein the predetermined position simulates the location of the nearest icon in the three dimensional view.

17. The method as recited in claim 12 wherein the travel (movement) of the icons slows down gradually in response to removal of the user input.

18. The method as recited in claim 12 wherein the travel of the plurality of icons exhibits a reversal of direction automatically when the end of the list of content items is reached.

19. A computer program product for selecting content on a display screen of a portable media player, the computer program product embodied in a non-transitory computer readable medium and comprising computer executable instructions for:

representing a plurality of content items by a plurality of icons having corresponding sizes positioned along a curved path in the display screen; and

varying the respective sizes of the icons as a function of the location of the icons relative to a predetermined position;

wherein the display screen is configured to cause the icons to travel along the curved path in response to a user input, and wherein each of the plurality of icons travels to the adjacent predetermined position along the curved path by a distance that varies in proportion to its size such that small sized icons move small distances and larger sized icons move larger distances.
