Is there a way to get the eye gaze trajectory - ie, the path the gaze follows on the screen - in Unity?
The documentation of UnityEngine.FoveInterface.GetEyeRays( ) mentions this - 'These rays are overwritten each frame, so you should not retain references to them across frames.'
What would be the best function to go about doing this in FoveInterface? I need to get gaze data from at least the past 10 frames to figure out the trajectory.
