Using Deep Learning to Increase Eye-Tracking Robustness, Accuracy, and Precision in Virtual Reality

no code implementations28 Mar 2024 Kevin Barkevich, Reynold Bailey, Gabriel J. Diaz

Algorithms for the estimation of gaze direction from mobile and video-based eye trackers typically involve tracking a feature of the eye that moves through the eye camera image in a way that covaries with the shifting gaze direction, such as the center or boundaries of the pupil.

Deep Domain Adaptation: A Sim2Real Neural Approach for Improving Eye-Tracking Systems

no code implementations23 Mar 2024 Viet Dung Nguyen, Reynold Bailey, Gabriel J. Diaz, Chengyi Ma, Alexander Fix, Alexander Ororbia

In remedy, we use dimensionality-reduction techniques to measure the overlap between the target eye images and synthetic training data, and to prune the training dataset in a manner that maximizes distribution overlap.
