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 environmentThe 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 viewNavigation 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

本研究使用一种新的运动界面在虚拟空间中行走，进行了有关导航性能的实验。虽然步行是最直观的运动方式，但在虚拟环境的大多数应用中不提供来自步行的本体感受反馈。该装置采用了一个转台，其上安装有两个运动平台。运动平台跟踪脚并将它们带回中立位置。用户可以在保持位置的同时在虚拟空间中物理地行走。运动平台垂直移动，模拟不平坦的表面。步行者可以在保持该位置的同时爬上或走下虚拟楼梯。GaitMaster与球形沉浸式显示器相结合，覆盖全视野导航性能通过路径再现测试进行测量。受试者沉浸在虚拟楼梯中。受试者首先前往目标物体。在他们到达目标物体后，目标物体消失了，被要求返回目标物体放置的地方。实验结果表明，该方法具有较好的三维空间定量识别性能
