A fun tool I hacked together in a few hours to be able to control any game with my eyes using my Tobii Eye Tracker.
Tested in a few games, however I assume it would work for pretty much any game. The DirectX overlay may trigger some anticheats, so be careful and use at own risk!
All files needed are in the repo, however after building you may need to copy some of the tobii dll's into the programs directory.
