I wonder - how did you deal with the issue of having to hold the head still? Or did you track that as well? If the head moves, the whole gaze information is not valid unless the movement is tracked as well. We have done that before by combining a gaze tracker with a 6DOF magnetic tracker, but that is neither a lowcost nor practical solution for home user. But it was really robust, that is true. However, using gaze to control anything (camera, avatar, whatever) is extremely bad idea - it is really tiring and eye movement is not something people can consciously control. Someone speaks next to you and you turn your head reflexively - throwing the whole system for a loop. At best it could be used to determine what you are looking at passively and use that for either some kind of feedback, perceptually-enhanced rendering or just to make the av look at the same thing to improve the facial expressions for the others looking at you.
