Hey Antoine, Very Good solution there. Can i please know on what method/basis have you tracked the gaze from iris center/s . Thank you.

Hi @Madankumar90 Thank you! This part is quite simple. I made a function horizontal_ratio() that returns a number between 0.0 and 1.0 that indicates the horizontal direction of the gaze. The extreme right is 0.0, the center is 0.5 and the extreme left is 1.0. To do that, I divide the iris coordinate (that I calculated previously) with the eye width.

Thank you for the earliest reply Antoine.
