Abstract

An apparatus for gesture recognition, according to aspects of the disclosure contained herein, include a processing system configured to obtain at least one physical dimension of a user and determine a gesture of the user based on the at least one physical dimension independent of a location of the user relative to the apparatus. A method for gesture recognition is also disclosed.

Claims

1. An apparatus for gesture recognition comprising:

a processing system configured to obtain at least one physical dimension of a user, and determine a gesture of the user based on the at least one physical dimension independent of a location of the user relative to the apparatus.

2. The apparatus of claim 1, wherein the processing system is further configured to identify at least one movement of the user, and determine the gesture of the user based also on the at least one identified movement.

3. The apparatus of claim 2, wherein the processing system is further configured to determine the gesture as a calibration of scale based on a relationship between the at least one physical dimension of the user and the at least one movement of the user.

4. The apparatus of claim 3, wherein the relationship is defined by at least one of an equation or a lookup table comprising at least one association between the at least one physical dimension of the user and the at least one movement of the user.

5. The apparatus of claim 2, wherein identifying the at least one movement comprises capturing the at least one movement from at least one of a remote accelerometer, a remote ranging sensor, or a remote gyro.

6. The apparatus of claim 1, wherein the at least one physical dimension comprises at least one of a height of the user, a length of an arm span of the user, or a distance of the user from the apparatus.

7. The apparatus of claim 1, wherein the at least one physical dimension is determined by at least one of:

receiving an input from the user, receiving information from at least one sensor positioned proximate to ground and a device held by the user at a physical height of the user, receiving information from a handheld device moved between a first position proximate to ground and a second position proximate to at a physical height of the user, or prompting the user to lift at least one arm until parallel to ground to measure arm span of the user.

8. A method for gesture recognition comprising:

obtaining at least one physical dimension of a user; and

determining a gesture of the user based on the at least one physical dimension independent of a location of the user relative to an apparatus.

9. The method of claim 8, further comprising identifying at least one movement of the user, wherein the gesture of the user is determined based also on the at least one identified movement.

10. The method of claim 9, wherein the gesture of the user is determined as a calibration of scale based on a relationship between the at least one physical dimension of the user and the at least one movement of the user.

11. The method of claim 10, wherein the relationship is defined by at least one of an equation or a lookup table comprising at least one association between the at least one physical dimension of the user and the at least one movement of the user.

12. The method of claim 9, wherein the identifying the at least one movement of the user comprises capturing the at least one movement from at least one of a remote accelerometer, a remote ranging sensor, or a remote gyro.

13. The method of claim 8, wherein the at least one physical dimension comprises at least one of a height of the user, a length of an arm span of the user, or a distance of the user from the apparatus.

14. The method of claim 8, wherein the obtaining of the at least one physical dimension comprises at least one of:

receiving an input from the user, receiving information from at least one sensor positioned proximate to ground and a device held by the user at a physical height of the user, receiving information from a handheld device moved between a first position proximate to ground and a second position proximate to at a physical height of the user, or prompting the user to lift at least one arm until parallel to ground to measure arm span of the user.

15. An apparatus for gesture recognition comprising:

means for obtaining at least one physical dimension of a user; and

means for determining a gesture of the user based on the at least one physical dimension independent of a location of the user relative to the apparatus.

16. The apparatus of claim 15, further comprising means for identifying at least one movement of the user, wherein the means for determining a gesture is configured to determine the gesture based also on the at least one identified movement.

17. The apparatus of claim 16, wherein the means for determining a gesture is configured to determine the gesture as a calibration of scale based on a relationship between the at least one physical dimension of the user and the at least one movement of the user.

18. The apparatus of claim 17, further comprising means for storing a lookup table comprising the relationship between the at least one physical dimension of the user and the at least one movement of the user.

19. The apparatus of claim 17, wherein the relationship is defined by at least one of an equation or a lookup table comprising at least one association between the at least one physical dimension of the user and the at least one movement of the user.

20. The apparatus of claim 16, wherein the means for identifying the at least one movement of the user comprises means for capturing the at least one movement from at least one of a remote accelerometer, a remote ranging sensor, or a remote gyro.

21. The apparatus of claim 15, wherein the at least one physical dimension comprises at least one of a height of the user, a length of an arm span of the user, or a distance of the user from the apparatus.

22. The apparatus of claim 15, wherein the means for obtaining the at least one physical dimension comprises at least one of:

means for receiving an input by the user, means for receiving information from at least one sensor positioned proximate to ground and a device held by the user at a physical height of the user, means for receiving information from a handheld device moved between a first position proximate to ground and a second position proximate to at a physical height of the user, or means for prompting the user to lift at least one arm until parallel to ground to measure arm span of the user.

23. A computer program product comprising:

a computer-readable medium comprising codes executable to cause an apparatus to;

obtain at least one physical dimension of a user; and

determine a gesture of the user based on the at least one physical dimension independent of a location of the user relative to an apparatus.

24. A game console for gesture recognition comprising:

a receiver configured to receive information from a user; and

a processing system configured to obtain at least one physical dimension of the user based on the information, and determine a gesture of the user based on the at least one physical dimension independent of a location of the user relative to the game console.
