项目摘要
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 environments. We developed an infinite surface driven by actuators for enabling a sense of walking. Torus-shaped surfaces are selected to realize the locomotion interface. The device employs twelve sets of treadmills. These treadmills are connected side-by-side and driven in perpendicular directions. The virtual infinite surface is generated by the motion of the treadmills. A walker can go in any direction while his/her position is fixed in the real world. The device is named "Torus Treadmill." Navigation performance was measured by path reproduction tests. Subjects were immersed in a virtual grass-covered plain on which a cone-shaped target object was placed. 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. We also set two target objects and the subject traveled along a bent path. We compared two locomotion modes : walking on the Torus Treadmill and moving purely by joystick operation. The results of the bent path experiment showed that accuracy of path reproduction of Torus Treadmill mode is better than that of Joystick mode.
本研究使用一种新的运动界面在虚拟空间中行走,进行了关于导航性能的实验。虽然步行是最直观的运动方式,但在大多数虚拟环境应用中,行走的本体感觉反馈并不提供。我们开发了一个由驱动器驱动的无限表面,以实现行走感。选择环面曲面实现运动界面。该装置使用了12台跑步机。这些跑步机并排连接,并在垂直方向上运行。虚拟无限表面是由跑步机的运动产生的。在现实世界中,步行者的位置是固定的,可以朝任何方向移动。该设备被命名为“环形跑步机”。通过路径再现测试来测量导航性能。受试者沉浸在一个虚拟的草地覆盖的平原上,上面放着一个锥形的目标物体。受试者首先移动到目标物体。在他们到达后,目标物体消失了,被安置的受试者被要求回到目标物体被放置的地方。我们还设置了两个目标物体,实验对象沿着弯曲的路径行进。我们比较了两种运动模式:在Torus跑步机上行走和纯粹通过操纵杆操作移动。弯曲路径实验结果表明,环形跑步机模式的路径再现精度优于操纵杆模式。
