This Demonstration computes the motion/pursuit law in the two-dimensional horizontal fixation plane of the eyes. The observer is looking mainly at F on the vertical axis, but also sees D as he translates to the right at speed equal to the interocular distance per second.


We do not know a theoretical explanation for the rough approximation of the peak motion pursuit law by the 2D relative distance, but this Demonstration compares , , and the 2D signed relative distance, . It also lets you vary time and compare the motion/pursuit law at other times. You can drag the distractor point and the fixate distance is variable.
