Thanks for your reply. What I was doing with the REX and the Gaze SDK was to determine the eyes vergence through the distance between the 2 gaze points. In this way I was able to determine if the user was focusing on the screen or through the screen.
I’d really like to find a way to do the same (vergence detection) with the EyeX and the EyeX SDK without falling back to the Gaze SDK. Do you think that would be possible?
