title: Positional tracking using kinect - how to determine head position in closed 3d space
body: <p>I suppose kinect standard way of usage is to put this device in some fixed position and let it do its calculation e.g. head tracking of someone which moves in front it.</p>
  
  <p>But my use case is different. What I need to do is change the frame of reference - attach kinect to the head and start moving with it around the room. Then I need to calculate its position within the room (I have the room already mapped into memory).</p>
  
  <p>So tracking should be now based on current device position itself and its relation with the room walls, floor and ceiling. As I understand kinect should be able to reflect light from the walls and give the deph - of what is my current distance from the wall etc. I need to get some information if this is even possible to achieve.</p>
  
  <p>Can you provide me some constructive references, where I could go much deeper into the topic, for being able to start the implementation of desired behaviour then ?</p>
