Can open-source eye tracking be THIS accurate?
DIY stereo eye tracking with professional accuracy.
In this video, I test the accuracy of a DIY eye tracking system that you can build for $34 and install in any VR headset. All parts and open-source software are available at the links below. The included Unity script also allows you to test the accuracy of your own system at home.
Results show that the angular error at roughly 5 and 10 degrees from center rivals the accuracy of similar commercial systems.
Instructions for installing the cameras are also available at jeoresearch.com/vrtracker.
