Paper Abstract

It has been shown that people consistently underestimate distances between objects in the depth direction as compared to the lateral direction. This study examined the use of artificially enhanced stereopsis (hyperstereopsis) in judging relative distances. The data showed that doubling interocular distance by means of a telestereoscope reduced the illusory compression of depth: subjects who viewed the scene without the telestereoscope averaged a depth compression of 0.28. Subjects who used the telestereoscope yielded an average compression of 0.40. Individual verbal self-reports of depth compression effects were unreliable, pointing out the value of quantitative experimental methods.
