PDF: High-speed Gaze-oriented Projection by Cross-ratio-based Eye Tracking with Dual Infrared Imaging

Abstract

While gaze-oriented projection can be high-resolution and wide-area display, conventional methods have difficulties in handling quick human eye movements. In this paper, we propose a high-speed gaze-oriented projection system using a synchronized high-speed tracking projector and cross-ratio-based eye tracking. The tracking projector with a high-speed projector and rotational mirrors enables temporal geometric consistency of the projection. The eye tracking uses high-speed cameras and infrared lightings of different wavelengths, and can achieve fast and almost calibration-free due to the cross-ratio algorithm. We have experimentally validated the eye tracking speed and accuracy, system latency, and demonstrated gaze-oriented projection.
