Three Dimensional Perception Produced By Two 2 Dimensional Geometric Patterns Presented With Brief Exposure Times And Time Intervals

This paper examines the three dimensional perception of human subjects who observe two 2 dimensional geometric patterns at brief exposure times and time intervals without the aid of a stereoscope. In general, presenting two 2 dimensional geometric patterns at the proper spacing, exposure times, and time intervals produces two dimensional movement perception in human observers. The observer sees a set of patterns moving in a lateral direction, from its first location to its second. The lateral two dimensional movement perception occurs over a wide range of exposure times and time intervals of stimulus patterns. Some geometric patterns presented at certain limited exposure times and time intervals, however, produce three dimensional patterns. The present research investigates the range of the conditions necessary for producing three dimensional pattern recognitions while presenting two dimensional patterns. The research may provide an understanding of human pattern recognition processes and aid in improving man-machine systems.
