Simple method to measure the visual axis of the human eye.

Abstract

We propose a simple method to measure the angle "α" that the visual axis (VA) makes with the optical axis of the human eye. In this method, we capture the images of the pupil from three different angles, one along the VA and the other two along angles that are symmetrical with respect to the VA. These views of the pupil are captured simultaneously by a… (More)
