Chapter 3. Skeletal Tracking
Skeletal tracking allows applications to recognize people and follow their actions. Skeletal tracking combined with gesture-based programming enables applications to provide a natural interface and increase the usability and ease of the application itself.
In this chapter we will learn how to enable and handle the skeleton data stream. For instance, we will address the following:
Tracking users by analyzing the skeleton data streamed by Kinect and mapping them to the color stream
Understanding what joints are and which joints are tracked in the near and seated mode
Observing the movements of the tracked users to detect simple actions
Mastering the skeleton data stream enables us to implement an application by tracking the user's actions and to recognize the user's gestures.
The Kinect sensor, thanks to the IR camera, can recognize up to six users in its field of view. Of these, only up to two users can be fully tracked, while the others are tracked from one single...
