Abstract

Virtual reality (VR) is popular across many disciplines and has been increasingly used in sports as a training tool lately. However, it is not clear whether the spatial orientation of humans works equally within VR and in the real-world. In this paper, two studies are presented, in which natural body movements were allowed and demanded. Firstly, a series of verbal and walking distance estimation tests were conducted in both the virtual and the real environment. The non-parametric Friedman test with pairwise comparisons showed no significant differences neither in verbal nor in walking distance estimations between the conditions (all p > 0.05). However, shorter distances (0.9-1.5 m) were estimated more precisely than larger distances (2.6-2.8 m) in both environments. Secondly, a self-developed route recall test to examine the spatial orientation was performed in the virtual and the real environment. The participants visually perceived the predefined route and were instructed to follow these routes with their eyes blindfolded and afterward to return to their starting position. Between the ending and the starting position, no difference between the two environments was observed (p > 0.05). Based on these two studies, the performance of the human spatial orientation preliminarily verified the same in a virtual and real environment.

摘要

虚拟现实 (VR) 在许多学科中都很流行，并且最近越来越多地在体育运动中用作训练工具。然而，尚不清楚人类的空间定向在 VR 中和在现实世界中是否同样有效。在本文中，提出了两项​​研究，其中允许和要求自然的身体运动。首先，在虚拟和真实环境中进行了一系列口头和步行距离估计测试。具有成对比较的非参数弗里德曼检验表明，在语言和步行距离估计方面，条件之间没有显着差异（所有 p > 0.05）。然而，在两种环境中，较短距离 (0.9-1.5 m) 的估计比较大距离 (2.6-2.8 m) 更精确。其次，在虚拟和真实环境中进行了自行开发的路线召回测试，以检查空间方向。参与者在视觉上感知到预定的路线，并被要求蒙住眼睛沿着这些路线走，然后返回到他们的起始位置。在结束位置和开始位置之间，没有观察到两种环境之间的差异（p > 0.05）。基于这两项研究，初步验证了人体空间定向在虚拟环境和现实环境中的表现是一致的。没有观察到两种环境之间的差异（p > 0.05）。基于这两项研究，初步验证了人体空间定向在虚拟环境和现实环境中的表现是一致的。没有观察到两种环境之间的差异（p > 0.05）。基于这两项研究，初步验证了人体空间定向在虚拟环境和现实环境中的表现是一致的。
