Interesting article.... Ok sounds really promising until you think about it and it occurs to me this has a rather serious flaw.... If your playing a racing game, and use your head to look down, left or right - you're no longer looking at the TV set. If your not looking at the TV set how are you going to see any of those things anyway ? Whilst this may work if your up close to your TV, if your sitting an average of 6 feet away from your TV your going have to to tilt your head, whilst looking in the opposite direction in order to maintain eye contact with the TV. That sounds uncomfortable to say the least.
