How track image to the hand with kinect?

Good day, folks!
Help me please - i want to track something image to the hand or to another part of body with kinect. How to do this? May be with special object ID?
I saw this tutorial with kinect & OSC http://www.youtube.com/watch?v=211PDo5litY
but it’s for Quarz composer, for MAC. I haven’t MAC:D, i’m PC user.
How can i do somthing like this?

Another question - how to connect 3D object with kinect? To manipulate with model.
Like in this example:

hi,

check out the kinect help files, skeleton should do this. you can get the position of various body parts.

And for anpther example check out this patch by Prototyping Interfaces - http://prototypinginterfaces.com/5-6/.

As for controlling a 3D object with the Kinect. My guess is they imported a collada file collada and connected it with the positions you retrieve from the Skeleton Node skeleton (kinect microsoft).
