Motion, Pursuit, Fixate, and Distractor (Visual Depth Perception 2)

fixate distance f

distractor distance d

This Demonstration shows the retinal motion and pursuit rates for your choice of

f

and

d

in the case of a fixate and distractor on the

y

axis and an observer moving at 6.5 cm/sec (interocular distance per second) to the right on the

x

axis. The observer's eyes are "fixed" on the point

F

(the "fixate" point). "Fixation" means the ray from

F

through the eye node strikes the fovea at the center of the retina (see: Fixation and Distraction (Visual Depth Perception 5)).
