Hi, Does that mean the tracking head position refers to the center of the virtual screen(active display plane/ physical screen) after calibration and profiling? And head rotation refers to center of tobii device(track box device space/ ucs)?
I also wish to know the coordinates used for LeftEye and RightEye position, gaze point position, at ucs or center of the physical screen, thanks!
I have spent some time googling it, but no answer has been found.
