User Calibration-free Method using Corneal Surface Image for Eye Tracking

Abstract

Various calibration methods to determine the point-of-regard have been proposed for eye tracking. Although user calibration can be performed for experiments carried out in the laboratory, it is unsuitable when applying an eye-tracker in user interfaces and in public displays. Therefore, we propose a novel calibration-free approach for users that is based on the use of the corneal surface image. As the environmental information is reflected on the corneal surface, we extracted the unwarped image around the point-of-regard from the cornea. The point-of-regard is estimated on the screen by using the unwarped image, and the regression formula is solved using these points without user calibration. We implemented the framework of the algorithm, and we confirmed the feasibility of the proposed method through experiments.
