| Research Abstract |
This research executed experiments regarding navigation performance using a new locomotion interface for walking through virtual space. Although traveling on foot is the most intuitive style of locomotion, proprioceptive feedback from walking is not provided in most applications of virtual environment
The Gait Master is a locomotion interface that creates sense of walking on uneven surface. The device employs a turntable on which two motion platforms are mounted. The motion platforms trace the feet and carry them back to the neutral position. The user can physically walk in a virtual space while the position is maintained. The motion platforms move vertically, which simulates uneven surface. The walker can climb up or go down a virtual staircase while the position is maintained. The GaitMaster is combined with a spherical immersive display, which covers full field of view
Navigation performance was measured by path reproduction tests. Subjects were immersed in a virtual staircase. The subjects first traveled to the target object. After they reached it, the target object disappeared and the rehomed subjects were asked to return to the place where the target object was placed. The results showed quantitative recognition performance of 3D space
