I am using the Pico Neo 3 Eye to capture some eye-tracking data. I've made a scene that displays on a Canvas the Gaze Origin Vector 3 using:
and the Gaze Direction Vector 3 using:
There are 2 problems:
1.) The Gaze Origin Vector 3 is always 0 (0,0,0) despite the fact that I move my head, so the origin should change. What I'm missing here?
2.) The Gaze Direction Vector 3 displays values ranging from -1 to 1. I read somewhere that 0,0 corresponds to the top right and 1,1 to the bottom left. How can I convert those values to world coordinates?
Thanks in advance.
