PS3 Eye cam = 125 FPS... US$ 35,00 + FreeTrack software... Freeware + Home built clip made with just IR leds, some wire and a support... < US$ 10,00.
And you have your 6DOF head tracking solution for less than US$ 50,00...
Knowledge is power. 6DOF head tracking is the way to go in flight sims, civil or military: it's natural, and easy to build and cheap, but people get overfixated with all "TrackIR"...
TrackIR is expensive. You can make something with the same quality with a PS3 Eye cam, Wiimote, or anything with good FPS and can see IR sources.
And, please... Head tracking technology NEVER was "patented" by NaturalPoint... It's OOOOOOOOOOLLLLLLLLLDDDDDDDDDDDDDDDDD technology... The only thing NP do was sell an overpriced solution to us, crazy sim customer...
