Yes I know this is not a good idea but I would like to experiment it.
I'd like to block the user's gaze in a certain part of the video. If the user tries to look outside of an authorized angle, the user's gaze will be blocked until he re-gaze in the angle.
EDIT : I would like to track the user head rotation without having to make the cameras follow this head rotation. Do you think it is possible ? (Actually i didn't find any way to just have 2 headTransform, one froze and the other not for example)
