Abstract

In this paper, we propose a wide-view parallax-free eye-mark recorder with a hyperboloidal half-silvered mirror. Our eye-mark recorder provides a wide field-of-view (FOV) video recording of the user's exact view by positioning the focal point of the mirror at the user's viewpoint. The vertical view angle of the prototype is 122 [deg] (elevation and depression angles are 38 and 84 [deg], respectively) and its horizontal view angle is 116 [deg] (nasal and temporal view angles are 38 and 78 [deg], respectively). We have implemented and evaluated a gaze estimation method for our eyemark recorder. Experimental results have verified that our eye-mark recorder successfully captures a wide FOV of a user and estimates a rough gaze direction.
