Abstract

Systems and methods according to the present invention address these needs and others by providing techniques for selecting items from a list that can be operated using, for example, a pointing device or a wheel device. According to exemplary embodiments of the present invention, items are arranged in a list as regions along a three dimensional helical surface. For example, each item can be allocated to a wedge-shaped region along the helical surface. The user can select items by, for example, using a pointing device to pick that item'"'"'s wedge or by using a wheel device to sequence through the items on the helical surface. Alternatively, a combination of a wheel and pointing device can be used to first scroll the helical surface, and then select an individual item. A clipping plane is used to remove parts of the helical surface from view once the user scrolls past them and reveal the selections in the cycle of the helical surface immediately beneath the clipping plane. Another feature of the helical surface menu is that it can be turned on its side and navigated at a coarse granularity.

Claims

1. A method for item selection comprising the steps of:

displaying a helical surface having an axis;

providing a plurality of items on said helical surface; and

selecting one of said plurality of items and

clipping from view items on said helical surface which are above said clipping plane.

2. The method of claim 1, wherein said plurality of items includes at least one of:

media items, software applications and features associated with a software application.

3. The method of claim 1, wherein said step of displaying a helical surface further comprises the step of:

displaying said helical surface with said axis oriented substantially perpendicular to a plane associated with a display screen.

4. The method of claim 3, further comprising the step of:

tilting said axis of said helical surface by a predetermined tilt angle relative to perpendicular to said plane associated with said display screen.

5. The method of claim 4, wherein said predetermined tilt angle is within the range of 30-60 degrees.

6. The method of claim 1, wherein said step of providing a plurality of items on said helical surface further comprises the step of:

allocating a portion of said helical surface to each of said plurality of items.

7. The method of claim 6, wherein said portion is wedge-shaped.

9. The method of claim 1, wherein said step of displaying further comprises the step of:

displaying said helical surface with said axis oriented substantially parallel to a plane associated with a display screen.

10. The method of claim 9, further comprising the step of:

displaying a plurality of category labels along said helical surface which identify groups of said plurality of items.

11. The method of claim 3, further comprising the step of:

changing a view of said helical surface such that it is displayed with said axis oriented substantially parallel to said plane associated with said display screen.

12. The method of claim 1, further comprising the step of:

scrolling through said plurality of items using a pointing device.

25. The method of claim 1, wherein said helical surface comprises an outer helix, an inner helix and a surface therebetween.

26. The method of claim 25, wherein said outer helix has a first helical angle associated therewith and said inner helix has a second helical angle associated therewith, said first helical angle being different from said second helical angle.

27. The method of claim 25, wherein said surface is at least partially translucent or transparent.

28. The method of claim 1, wherein said axis is linear.

29. The method of claim 11, further comprising the step of:

animating a transition between said step of displaying said helical surface with said axis oriented substantially perpendicular to said plane associated with said display screen and said step of changing said view of said helical surface such that it is displayed with said axis oriented substantially parallel to said plane associated with said display screen.

30. The method of claim 25, wherein said outer helix and said inner helix have at least one helical angle associated there with which varies as a function of length of said helical surface.
