I'm working on a UI project of source and I feel like toying around a bit with eye tracking. Sort of something along the lines of what the guys over at talon voice are doing.
I do however realize that my time budget and skill level doesn't afford writing stuff like this from scratch. As such my first question would be the following, do any of you have experience regarding open source eye tracking? If that's the case what have you been using and what are your experiences?
Also if any one here have been using Talon do you have any reviews on it. I'm a thinkpad pleb and can't really try it out. Is there a Linux equivalent?
