Abstract

Binocular parallax is one of the important information in depth perception. In this research, authors examined about the relation between the size of binocular parallax and work efficiency in the virtual reality environment. The liquid crystal shutter glasses were used for stereopsis. The subjects were five male university students who have nomal stereopsis. They could control the arm in the virtual world by 3-dimension mouse. They could pick the object by the arm and transport it. Their task was placing it on given location as fast as possible. The normal binocular parallax condition (the distance between viewpoints was about 6 cm) and the large binocular parallax condition (about 43cm) were set up as experiment conditions. Each condition was constructed 120 successive trials. The results of error and work time showed there was not a difference between two conditions except first 10 trials. In the first 10 trials, subjects made much error and it took long work time in the large binocular parallax condition. And after experiment the flicker fusion frequencies were reduced a little in the normal condition.
