I did more experiments with the position and the angle of the kinect relative with the PIMAX, got more accurate movements. If we had any kind of SDK prepared to work with low distances (or seated tracking) and heads with virtual HMD´s i think it would work great.
HAve you seen this? http://www.immotionar.com/
Another thing we need is some kind of filter to make smoother the experience while playing. Maybe im not introducing the values correctly in the settings of kinnect. Any kind of guide to this settings window would be great too.
