Document Summary
The eyes rotate at a velocity that matches the velocity of the head, allowing the image to remain stationary on the retina (tonic). The eyes will also rotate in the opposite direction of the head movement (phasic). The eye will have small saccadic movements that are important to visual perception: vor of different degrees or velocities. The eyes will still rotate to the opposite direction of your head. The fovea will be pointed at the moving object during pursuit. The eye constantly tries to capture the object with the fovea during fast pursuit. The eyes move in saccadic movements during fast pursuit and smooth during slow pursuit: slow saccadic vs normal reading. Eog patterns include increased distance between each trough (divergence) and it was less steep. The eyes moved quicker during normal reading: convergence vs divergence. Convergence was observed as sharp peaks when the eye moves from the far object to the close object.
