[Multiple Hands PIC] Kinect Chapter 8.   NITE Hands Tracker


This chapter was previously labelled as "NUI Chapter 16.5".


This chapter is about utilizing OpenNI's gesture and hands generators with NITE's hand points to track multiple hands, and draw the tracks as 'trails' on top of the Kinect's camera image, as shown on the right.

Hand point listeners were described in the previous chapter, and the coding here is similar. The main additional issues are getting NITE to recognize multiple hands (the default is only one), reporting session state changes, and rendering the hand point coordinates (which require real-world to screen coordinate mapping).
