Wonder how hard it would be to support facetracking, like the facetrack-noir
It might help with immersiveness, if your head movements translate to the head movement of the character.
I also heard of video glasses with accelerometer support! Now that would definitely be more scarier to play this game with. (after with a normal screen, you can just turn you head away from it. If its too scary)
One of the facetracking programs I was referring to is:
