Suivi du regard non intrusif en tête libre à partir d'images vidéo

The problem of eye gaze tracking has been researched and developed for a long time. The most difficult problem in the non-intrusive system of eye gaze tracking is the problem of head movements. Some of existing methods have to use two cameras and an active infrared (IR) illumination to solve this problem. Otherwise, with a single camera, the user has to hold the head uncomfortably still when performing a session of eye gaze tracking. If the head of the user moves away from original position, the accuracy of these eye gaze-tracking systems drops dramatically. In this paper, we propose a solution using a gaussian process for eye gaze tracking that allows free head movements with a single camera. Studia Informatica Universalis.
