The Hidden Math Behind 3D Eye Tracking

This video provides a detailed explanation of the 3D math behind eye tracking, which I have open-sourced in Python. This includes an explanation of the pupil fitting algorithms, 3D geometry, and ray projection used in commercial products. This is useful if you're building your own eye tracker, learning about computer vision, or just like to look at eyeballs. Code: https://github.com/JEOresearch/EyeTra...
