The next wave of video games will track your facial movements. You look left, and your character will look left too. The video decribes, "The TrackIR4: Pro is a head-tracking device that works by detecting infrared light reflected from three IR-reflective surraces on a 'TrackClip' that can attach to a hat, headphones or similar. The device tracks head motion in the full six degrees of freedom and translates it into game controls."
