No, no real budget, I have however looked at these cameras before and if this
project goes any further I would recommend better (faster) cameras - it is
necessary!

Yes, one of my objectives is to make it cheap and by using "normal" webcams.
The real task is done - I have built a 6DOF sensor and it works, but (!) I want
to make it faster. And these 80 ms are really nagging me.
I am also very interested in links and projects that I can read about 3D
tracking system like this in general and particularly head tracking.
