Hi Guribo, getting back to you with an update and question.
Eyeware Beam, our iOS app for head and eye tracking, is now in public beta, temporarily free. You can download it from the App Store : https://beam.eyeware.tech/.
We progressed with our Unity SDK, and were wondering: what data do you use from the Tobii eye tracker? For generating eye movements, do you use the 2D gaze point on the screen, or do you have access to a 3D ray coming from the eyes ?
I saw some comments that out-of-screen gaze makes the eyes blink, it sounds like you are then only using 2d screen gaze. If yes, would you like a 3D gaze ray that doesn’t have that issue?
