Kinect gesture recognition

I just want to know whether identification of objects like humans and gestures of body parts is done b开发者_开发知识库y Kinect or by the Xbox 360.

It's done on the Xbox. The Kinect only sends a depth map, rgb video and sound, which are processed by Microsoft's algorithms on the Xbox.

OpenNI comes with some tools (e.g. NITE) that do skeleton tracking and some gesture recognition for you, if you plan to program for the Kinect.
