Basic Operating Principles During tracking, Tobii Eye Trackers use infrared diodes to generate reflection patterns on the corneas of the subject’s eyes. These reflection patterns, together with other visual data about the subject, are collected by image sensors. Sophisticated image processing algorithms identify relevant features, including the eyes and the corneal reflection patterns. -
