In the last decade computers made possible the generation of static random-dot stereograms without monocular depth and familiarity cues but with controlled binocular disparities. In the '70s advances in computer technology led to the development of on-line generated dynamic random-dot stereograms. These novel methods brought a better understanding of binocular depth perception and its deficiencies. They led to improved quality inspection of LSI components by (a): the proper alignment of stereomicroscopes and (b): the proper screening of stereodeficient inspectors (about 15% of the population). Thus computers led to some new stimuli that gave unexpected insights into the classical field of binocular vision, which in turn led to an improved quality inspection methodology that helped build cheaper computers.
