Deflectometry Eye Tracking

Researchers at the University of Arizona have demonstrated an innovative approach that could revolutionize eye-tracking applications. Their study finds that integrating a powerful 3D imaging technique known as deflectometry with advanced computation has the potential to significantly improve state-of-the-art eye tracking technology.

Current eye-tracking methods can only capture directional information of the eyeball from a few sparse surface points, about a dozen at most. With the deflectometry-based method, researchers can use the information from more than 40,000 surface points, theoretically even millions, all extracted from only one single, instantaneous camera image.
