Controlling the camera with your head would be good for racing games. Like in GTR you can already get a headtracker which allows you to look around the car and look to the apex of a corner as your turning with the steering wheel. Works really well. And games like PGR would love it.
But the way Johnny Chung Lee uses it to create a holographic TV image, would be no problem to integrate into your bog standard fps with analog stick controlled movement. It' d just be a holographic fps, or h-fps.
