What I really want is almost the exact opposite of this. For long text, I want smart autoscroll that uses eye-tracking to keep me from ever having to make a manual adjustment. If my eyes are pointed at the bottom of the screen, speed up the scroll, and if they're at the top of the screen, slow down/reverse. With this kind of feedback system, the eye tracking doesn't even need to be all that precise.
I've used Enable Viacam (http://eviacam.sourceforge.net/index.php) to sort of do this using head tracking, but you don't really move your head that much when reading, and it's too sensitive to changes in seating position.
If this could be implemented correctly, I think the result would be a superior reading experience to any alternative so far.
