目前的研究旨在确定在虚拟现实环境中行走的个人是否通过由两个化身制成的孔，而不是由两个杆障碍物形成的孔，正如之前在现实世界环境中观察到的杆和人类障碍物之间的孔。11名健康的年轻成年人戴着头戴式虚拟现实显示器，沿着沿着10米的路径行走，并穿过位于距离起始位置5米处的虚拟孔径。参与者被指示在通过光圈时避免与障碍物碰撞。该实验是在一个区块设计中进行的，其中孔径由两个极点障碍物或两个化身创建。在这两种情况下，孔的宽度范围在每个参与者的肩宽的1.0- 1.8倍之间。无论光圈是由虚拟杆还是化身创建的，参与者都旋转了所有光圈大小的肩膀，结果发现肩膀旋转角度，旋转开始，步行速度或穿越两种类型障碍物时的速度没有显着差异。因此，在现实世界中观察到的人与杆障碍物之间的回避行为差异似乎并没有转化为虚拟现实环境。有可能在化身不移动的实验期间，它们不具有被建议为负责在走过真实的人类障碍物时使用的增加的谨慎的类似人类的品质，而是被视为任何普通的障碍物。
The current study set out to determine whether individuals walking in a virtual reality environment pass through apertures made of two avatars differently than apertures created by two pole obstacles, as previously observed between pole and human obstacles in real-world environments. Eleven healthy young adults wore a head-mounted virtual reality display, walked along a 10 m path and passed through a virtual aperture located 5 m from the starting location. Participants were instructed to avoid colliding with the obstacles when passing through the aperture. The experiment was conducted in a block design, where the aperture was either created by two pole obstacles or by two avatars. In both conditions, the width of the aperture ranged between 1.0–1.8x each participant’s shoulder width. Regardless of whether the aperture was created by the virtual poles or the avatars, participants rotated their shoulders for all aperture sizes and results found no significant differences in shoulder rotation angle, onset of rotation, walking speed or velocity at time of crossing between the two types of obstacles. Therefore, it appears that the differences in avoidance behaviours observed in real-world settings between people and pole obstacles is not translated to a virtual reality environment. It is possible that during experiments in which the avatars do not move, they do not possess human-like qualities suggested to be responsible for the increased caution used when walking through real human obstacles and instead, are treated as any ordinary obstacle.
