Binocular Disparity versus Depth (Visual Depth Perception 9)

Requires a Wolfram Notebook System
Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.
This Demonstration shows that binocular disparity alone does NOT determine the relative depth of a distractor.

Details
Binocular disparity is explained in more detail in the Demonstration "Binocular Disparity (Visual Depth Perception 7)" and the addition of convergence for depth is in "Disparity, Convergence, and Depth (Visual Depth Perception 10)" (see Related Links).
For this Demonstration, we also give the value of the retinal motion rate for an observer moving at 6.5 cm/sec (interocular distance per second).
Motion parallax is asymptotic to binocular disparity at long fixate distances; see the Demonstration "Dynamic Approximation of Static Quantities (Visual Depth Perception 14)" in the Related Links.
