Speed, Pursuit, M/P Ratio, and Depth (Visual Depth Perception 16)

This Demonstration shows absolute depth from your choice of pursuit rate and motion/pursuit ratio for the case of a fixate and distractor on the axis and an observer moving at 6.5 cm/sec (interocular distance per second) to the right on the axis. The retinal motion rate of "Speed, Motion, Pursuit, and Depth (Visual Depth Perception 15)" is the geometric input, but experiments show that the brain uses the motion/pursuit ratio, so this Demonstration allows you to vary that quantity directly.

This Demonstration is for the case of a fixate and distractor on the axis and an observer moving at 6.5 cm/sec (interocular distance per second) to the right on the axis. See "Speed, Motion, Pursuit, and Depth (Visual Depth Perception 15)" for additional details. This Demonstration only differs from that one in allowing you to control the motion/pursuit RATIO rather than the separate geometric inputs. Psychophysical experiments suggest that the brain uses the ratio in visual depth perception. The neurophysiology combining these inputs is not yet understood.
