Abstract

In accordance with one implementation, a method is illustrated that allows a computing device to determine a user input. The method includes detecting one or more user input objects in a 3-dimensional field relative to a 2-dimensional surface. The method also includes determining coordinates for the one or more user input objects relative to the 2-dimensional surface. And, the method further includes determining a user input based on the coordinates.

Claims

1. A method of determining user input in a 3D field relative to a 2D surface, the method comprising:

detecting one or more user input objects in a 3-dimensional field relative to a 2-dimensional surface;

determining coordinates for the one or more user input objects relative to the 2-dimensional surface;

determining a user input based on the coordinates.

12. The method of claim 1 and further comprising:

varying a display element characteristic based on a change in a proximity of at least one input object to the 2-dimensional surface.

13. The method of claim 12 wherein varying the display element characteristic comprises varying the diameter of a circle used for the display element.

14. The method of claim 1 wherein determining a user input comprises:

determining a command from a user without the user touching a keyboard or a display to issue the command.

15. The method of claim 1 wherein determining a user input comprises:

determining a 3 dimensional gesture.

16. The method of claim 1 and further comprising:

disregarding one or more input objects when multiple input objects are detected.

2-11. -11. (canceled)

17. One or more computer-readable storage media encoding computer-executable instructions for executing on a computer system a computer process, the computer process comprising:

detecting one or more user input objects in a 3-dimensional field relative to a 2-dimensional surface;

determining coordinates for the one or more user input objects relative to the 2-dimensional surface;

determining a user input based on the coordinates.

26. The one or more computer-readable storage media of claim 17 wherein the computer process further comprises:

varying a display element characteristic based on a change in a proximity of at least one input object to the 2-dimensional surface.

27. The one or more computer-readable storage media of claim 26 wherein varying the display element characteristic comprises varying the diameter of a circle used for the display element.

28. The one or more computer-readable storage media of claim 17 wherein determining a user input comprises:

determining a command from a user without the user touching a keyboard or a display to issue the command.

29. The one or more computer-readable storage media of claim 17 wherein determining a user input comprises:

determining a 3 dimensional gesture.

30. The one or more computer-readable storage media of claim 17 wherein the computer process further comprises:

disregarding one or more input objects when multiple input objects are detected.
