Abstract

Presented is method and system for processing a gesture performed by a user of an input device. The method comprises detecting the gesture and determining a distance of the input device from a predetermined location. A user command is then determined based on the detected gesture and the determined distance.

Claims

1-15. -15. (canceled)

16. A method of processing a gesture performed by a user of an input device, the method comprising:

detecting the gesture;

determining a distance of the input device from a predetermined location; and

determining a user command based on the detected gesture and the determined distance,

the detected gesture at a first determined distance indicating a first command, and the detected gesture at a second determined distance indicating a second command different than the first command

17. The method of claim 16, wherein detecting the gesture comprises:

comparing the determined distance with a threshold distance,

the detected gesture at the determined distance less than the threshold distance indicating a first type of interaction, and the detected gesture at the determined distance greater than the threshold distance indicating a second type of interaction.

18. The method of claim 17, wherein the first type of interaction emulates a touch interaction and the second type of interaction emulates a hover interaction.

19. The method of claim 17, wherein the first type of interaction comprises a selection command and the second type of interaction comprises a movement command

20. The method of claim 16, wherein determining the distance of the input device from the predetermined location comprises generating a depth image and processing the depth image in accordance with a depth recognition process.

21. The method of claim 16, wherein determining the distance of the input device from the predetermined location comprises determining the distance of the input device relative to a display.

22. The method of claim 16, wherein determining the distance of the input device from the predetermined location comprises determining the distance of the input device relative to the user'"'"'s body.

23. The method of claim 16, wherein the input device comprises a body part of the user.

24. The method of claim 16, wherein the input device comprises a device held or operated by the user.

31. The system of claim 16, wherein the same detected gesture at a determined distance less than a threshold distance indicates a first type of interaction, and the same detected gesture at a determined distance greater than the threshold distance indicates a second type of interaction.

32. The system of claim 16, wherein the first type of interaction comprises a selection command and the second type of interaction comprises a movement command

33. The system of claim 16, wherein the distance of the input device from the predetermined location comprises a distance of the input device relative to at least one of a display and the user'"'"'s body.

34. The system of claim 16, wherein the input device comprises at least one of a body part of the user and a device held or operated by the user.

35. The system of claim 16, wherein the imaging device comprises a range camera.

25. A system for processing a gesture performed by a user of an input device, the system comprising:

means for detecting the gesture;

means for determining a distance of the input device from a predetermined location; and

means for determining a user command based on the detected gesture and the determined distance,

the detected gesture at a first determined distance indicating a first command, and the detected gesture at a second determined distance indicating a second command different than the first command.

26. The system of claim 25, the detected gesture at the determined distance less than a threshold distance indicating a first type of interaction, and the detected gesture at the determined distance greater than the threshold distance indicating a second type of interaction.

27. The system of claim 25, wherein means for determining the distance of the input device from the predetermined location is to process a depth image in accordance with a depth recognition process.

28. The system of claim 25, wherein means for determining the distance of the input device from the predetermined location is to determine the distance of the input device relative to a display.

29. The system of claim 25, wherein means for determining the distance of the input device from the predetermined location is to determine the distance of the input device relative to the user'"'"'s body.

30. A system for processing a gesture performed by a user of an input device, the system comprising:

an imaging device to produce a depth image of the gesture performed by the user of the input device;

a processor to detect the gesture, determine a distance of the input device from a predetermined location based on the depth image, and determine a user command based on the detected gesture and the determined distance,

wherein a same detected gesture at different determined distances indicates different commands.
