TL;DR: In this article, a subject-controlled smooth pursuit method was proposed for the horizontal axis which is more rapid, requires no interpolation and no linearity assumption, and is as accurate as the fixation point method usually used.
Abstract: A subject-controlled smooth pursuit method of calibration of eye movement apparatus is proposed for the horizontal axis which is more rapid, requires no interpolation and no linearity assumption, and is as accurate as the fixation point method usually used. The zero drift method of verification proposed then permits accuracy to be estimated in a way that distinguishes apparatus errors from fixation errors. This is only possible in the fixation point method by asking the subject to make repeated long fixations.
