FaceTrackNoIR has a setting to use Tobii. Have you tried that? I can’t imagine that eye tracking is going to work that well when your eyes are darting about all over the place, or does it do face tracking too?
Dee-Jay: It’s a sort of detector bar, that comes as a standalone device or, often, built into the screen bezel of some laptops. It allows you to move cursors and whatnot with your gaze. I think that in general, your game has to support it - I’m guessing that FaceTrackNoIR must “intercept” the signal - and turn it into the normal type of headtracker signal that sims can use - like TrackIR.
I’ll look into it, but basically tobbi eye tracking 4c has head tracking as well so you move your head and look where you want to look and the camera will look where your looking basically, if you set it up right it’s pretty useful I bought mine separately but it’s a bar that sits on your monitor alot of laptops have it built in.
