Trackir on consoles?, here some clues..

I know trackIR is nice, but it is expensive. I'm not sure about the XBox but PS3 already has the tech to do something like the trackIR with the ps eye, which is quite a bit cheaper. You could use it to track head movement with a little programming. Sure it won't be as crisp as IR, but it should be good enough, and you won't have to wear a hat.
