Abstract

The relationship between the amount of rotation of the eyeball and the amount of rotation of the line of sight was investigated. The planar model and ellipsoidal model were compared as the trajectory of the center of the pupil. An evaluation of precision was carried out by measuring the discrepancy between the direction of the target and the estimated direction of the line of sight. The experimental results showed that the planar model was more precise than the ellipsoidal model. The center of rotation of the eyeball seems to translate along the oblique rotation of the eyeball.
