A dynamic and static microcomputer-based stereogram generator

A dynamic and static generator for random element stereograms is presented. The system allows any solid shaped target to be programmed and vary in size or shape, movement and disparity. The random element stereogram generator (RESG) creates static or dynamic random red and green elements on a color monitor. Target size is dependent on overall monitor size, and programmable movement varies over a large range with three types of movement possible: sinusoidal, triangle, and square wave. The versatility of the system is demonstrated with eye movement and visual evoked-response data.<
