Koren said:There's absolutely no way that kinect can do head tracking with that. Resolution is far too low to measure accurately head rotations, especially with something nearly spherical like a head.
When it's done with a system like kinect, usually the rotation is measured by the normal camera by computing the position of the eyes... difficult to reproduce with a helmet
A simple webcam (such as PS Eye) is sufficient, if you put beacons on the helmet (think 4 "move balls" arranged in a 3D fashion, e.g.). Putting gyros/magnetometers in the helmet would greatly help, though.
Just how "smart" is Kinect. Maybe you could paint a couple eyeballs onto the outer shell and fool it into identifying them as eyes?
