Cross-ratio method can estimate point-of-gaze on a screen without performing a hardware calibration, and it has a tolerance of the head movement. However, this method requires the display, which near-infrared light-emitting-diodes are attached on, to detect screen corners. Therefore, we developed a polarization camera system to detect screen reflection on cornea without near-infrared-light emission. Most of the liquid crystal display has an internal polarizing filter, and thus, the transmitted light can be controlled by the external polarizing filter. We performed the evaluation experiment of cross-ratio based gaze estimation using display corner detection from polarized images.
