Tracking and Separation (Visual Depth Perception 11)
We study the case of an observer moving at right angles to the aim of the head, fixing his eyes on a (fixate) point F and also observing a distractor D. The important angles for depth perception by motion parallax are and . The angle is mathematically helpful.
θ
α
β=α-θ
To animate motion in time, click the [+] next to the "time " slider and click play [>]. The changing position of the distractor on the retina is "motion parallax".
