Webb11 apr. 2024 · Eye tracking is your eyes’ ability to move seamlessly from focusing on one object to another. It requires the muscles of both of your eyes to move perfectly in sync … The optokinetic response (OKR) is a combination of a slow-phase and fast-phase eye movements. It is seen when an individual tracks (pursuit movement) a moving object with their eyes, which then moves out of the field of vision, a point at which their eyes move back to the initial position (saccade movement) when they first saw the object. The reflex develops at about 6 months of age.
