即使在最先进的虚拟现实(VR)设置中，参与者在虚拟环境中导航时也经常感到迷失。在心理学实验中，这种定向障碍通常可以通过广泛的训练来弥补。目前的研究通过一项快速的指向起点的任务来调查参与者的方向感，而不需要任何培训或表现反馈。这使得我们能够研究参与者在VR中的直观空间定向，同时将较高认知能力和补偿策略的影响降至最低。在视觉上显示了沿着一段或两段轨迹的被动偏移之后，参与者被要求“尽可能准确和快速地”指出运动的起源。尽管使用了84度乘63度视野的高质量视频投影，但参与者的整体表现相当差。此外，16名参与者中有6名表现出惊人的质量错误，即一致的左右混淆，这在可比的现实世界实验中没有观察到。综上所述，这项研究表明，即使是身临其境的高质量视频投影系统，也不一定足以在VR中实现自然的空间定位。我们认为，一个快速的点到点范例可以是一个有用的工具，以评估和改进虚拟现实设置的有效性，使其能够实现自然和不受阻碍的空间定向和性能。
Even in state-of-the-art virtual reality (VR) setups, participants often feel lost when navigating through virtual environments. In psychological experiments, such disorientation is often compensated for by extensive training. The current study investigated participants' sense of direction by means of a rapid point-to-origin task without any training or performance feedback. This allowed us to study participants' intuitive spatial orientation in VR while minimizing the influence of higher cognitive abilities and compensatory strategies. After visually displayed passive excursions along one-or two-segment trajectories, participants were asked to point back to the origin of locomotion "as accurately and quickly as possible". Despite using a high-quality video projection with a 84deg times 63deg field of view, participants' overall performance was rather poor. Moreover, six of the 16 participants exhibited striking qualitative errors, i.e., consistent left-right confusions that have not been observed in comparable real world experiments. Taken together, this study suggests that even an immersive high-quality video projection system is not necessarily sufficient for enabling natural spatial orientation in VR. We propose that a rapid point-to-origin paradigm can be a useful tool for evaluating and improving the effectiveness of VR setups in terms of enabling natural and unencumbered spatial orientation and performance.
