在虚拟环境(VE)中的导航界面的类型-头从动或间接-决定是否本体感觉反馈刺激在运动过程中存在。此外,可以使用远距传送,其不提供连续的移动,而是在大距离上不连续地移位视点。进行了两部分实验。第一部分调查是否头从导航提供了一个虚拟环境中的空间学习的优势。第二部分研究了使用瞬间移动时预期的作用。结果表明,在虚拟环境中,主从式导航在空间知识获取方面优于间接式导航。预见传送的目的地,在很大程度上防止了位移后的迷失方向,但不是完全避免。如果传送涉及到视线方向的旋转,那么预期所需的时间就会增加。这项研究显示了潜在的附加值,使用一个头从导航界面-例如,当使用VE用于培训目的-并提供了实用的指导方针,在VE应用程序中使用心灵传输。
The type of navigation interface in a virtual environment (VE)---head slaved or indirect---determines whether or not proprioceptive feedback stimuli are present during movement. In addition, teleports can be used, which do not provide continuous movement but, rather, discontinuously displace the viewpoint over large distances. A two-part experiment was performed. The first part investigated whether head-slaved navigation provides an advantage for spatial learning in a VE. The second part investigated the role of anticipation when using teleports. The results showed that head-slaved navigation has an advantage over indirect navigation for the acquisition of spatial knowledge in a VE. Anticipating the destination of the teleport prevented disorientation after the displacement to a great extent but not completely. The time that was needed for anticipation increased if the teleport involved a rotation of the viewing direction. This research shows the potential added value of using a head-slaved navigation interface---for example, when using VE for training purposes---and provides practical guidelines for the use of teleports in VE applications.
