SKELETAL JOINT RECOGNITION AND TRACKING SYSTEM
First Claim
1. In a system comprising a computing environment coupled to a capture device for capturing position information from a scene, a method of gesture recognition, comprising:
- a) receiving position information from a user in the scene, the user having a first body part and second body part;
b) recognizing a gesture from the first body part;
c) ignoring a gesture performed by the second body part; and
d) performing an action associated with the gesture from the first body part recognized in said step b).

Abstract
A system and method are disclosed for recognizing and tracking a user'"'"'s skeletal joints with a NUI system and further, for recognizing and tracking only some skeletal joints, such as for example a user'"'"'s upper body. The system may include a limb identification engine which may use various methods to evaluate, identify and track positions of body parts of one or more users in a scene. In examples, further processing efficiency may be achieved by segmenting the field of view in smaller zones, and focusing on one zone at a time. Moreover, each zone may have its own set of predefined gestures which are recognized.

9. In a system comprising a computing environment coupled to a capture device for capturing position information from a scene, a method of recognizing and tracking body parts of a user, comprising:
-
a) obtaining body part proposals from a stateless body part proposal system receiving position information from the scene; b) obtaining body part proposals from a stateful body part proposal system; and c) reconciling the candidate body parts into whole or partial skeletons by a skeleton resolution system. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A computer-readable storage medium capable of programming a processor to perform a method of recognizing and tracking body parts of a user having at least limited use of at least one immobilized body part, the method comprising:
-
a) receiving an indication from the user of the identity of the at least one immobilized body part; b) identifying a first group of joints of the user, the joints not included within the at least one immobilized body part; c) identifying positions of joints in the first group of joints; and d) performing an action based on positions of the joints identified in said step c). - View Dependent Claims (18, 19, 20)
