1A1-Q05 Improvement of Robustness in Pupil Detection Assuming a Constant Interpupillary Distance in a Video-based Eye-Gaze Detection Device : A Solution of Glasses Reflection Problem(Communication Robot)

Abstract

In the eye-gaze detection method using stereo-cameras, when a user wears eyeglasses, the glasses reflection of near-infrared LED light sources would be misdetected as the pupil. To improve the robustness of pupil detection, we propose novel pupil searching and tracking methods assuming that 3-D interpuillary distance is constant. The experimental results show the accuracy of pupil searching and tracking was improved compared to the conventional method.
