Yeah.. I've literally tried 20 solutions, and most can not detect gaze location well. Gazehawk included.

  That may have been one of the reasons why they didn't make it. Eye tracking is tricky. I worked a bit with two guys developing a commercial eye tracker in the 80's, it was a pretty sophisticated optical set-up that combined the image being looked at and the image of the person looking using a 45 degree angle 50% mirror, that made the job considerably easier. One of the complicating factors was that eye movements have a lot of noise in them that our brain has become very adept at filtering out so what we think our eyes are doing can be quite different from what they're really doing.
