GENERATION OF DYNAMIC RANDOM-ELEMENT STEREOGRAMS IN REAL-TIME WITH A SYSTEM BASED ON A PERSONAL-COMPUTER

A new system capable of generating static and dynamic random-element s tereograms is designed and implemented. The stereogram is composed of a rectangle that can be varied in size, element density, orientation, and horizontal and vertical disparities, and can be swept at several v elocities. The system is based on an inexpensive personal computer (Am iga 500), designed to work as a slave system under the control of a ho st computer (e.g. any personal computer). A colour monitor or two blac k and white monitors are suitable display devices to view the stereogr ams. This system is used to perform psycophysical experiments in human s and neurophysiological experiments in behaving monkeys, with the pur pose of studying depth perception and binocular vision.
