摘要: Video eye trackers rely on the position of pupil centre. However, centre can shift when size changes. This pupillary artifact is investigated for binocular vergence accuracy (i.e. fixation disparity) in near vision where smaller test phase than monocular calibration. A regression between recordings and disparity allows correcting artefact. corrected appeared to be favourable with respect reliability validity, i. e. correlation versus heterophoria. The findings provide a quantitative estimation artefact measured as function viewing distance luminance, both measures position.
