Teleporting is a popular interface to allow virtual reality users to explore environments that are larger than the available walking space. When teleporting, the user positions a marker in the virtual environment and is instantly transported without any self-motion cues. Five experiments were designed to evaluate the spatial cognitive consequences of teleporting and to identify environmental cues that could mitigate those costs. Participants performed a triangle completion task by traversing 2 outbound path legs before pointing to the unmarked path origin. Locomotion was accomplished via walking or 2 common implementations of the teleporting interface distinguished by the concordance between movement of the body and movement through the virtual environment. In the partially concordant teleporting interface, participants teleported to translate (change position) but turned the body to rotate. In the discordant teleporting interface, participants teleported to translate and rotate. Across all 5 experiments, discordant teleporting produced larger errors than partially concordant teleporting which produced larger errors than walking, reflecting the importance of translational and rotational self-motion cues. Furthermore, geometric boundaries (room walls or a fence) were necessary to mitigate the spatial cognitive costs associated with teleporting, and landmarks were helpful only in the context of a geometric boundary.

通过虚拟环境传送的空间认知影响。

传送是一种流行的界面,允许虚拟现实用户探索比可用步行空间更大的环境。传送时,用户在虚拟环境中放置一个标记,并在没有任何自运动提示的情况下立即传送。设计了五个实验来评估传送的空间认知后果,并确定可以减轻这些成本的环境线索。参与者通过在指向未标记的路径原点之前遍历 2 个出站路径腿来执行三角形完成任务。运动是通过步行或 2 种常见的传送界面实现来完成的,传送界面的区别在于身体运动与通过虚拟环境的运动之间的一致性。在部分一致的传送界面中,参与者传送到平移(改变位置)但转动身体旋转。在不和谐的瞬移界面中,参与者瞬移平移和旋转。在所有 5 个实验中,不一致的传送产生的误差比部分一致的传送产生的误差大,部分一致的传送产生的误差比行走大,这反映了平移和旋转自运动线索的重要性。此外,几何边界(房间墙壁或围栏)对于减轻与传送相关的空间认知成本是必要的,并且地标仅在几何边界的背景下才有帮助。(PsycInfo 数据库记录 (c) 2020 APA,保留所有权利)。不一致的传送产生的误差比部分一致的传送产生的误差大,部分一致的传送产生的误差比行走大,这反映了平移和旋转自运动线索的重要性。此外,几何边界(房间墙壁或围栏)对于减轻与传送相关的空间认知成本是必要的,并且地标仅在几何边界的背景下才有帮助。(PsycInfo 数据库记录 (c) 2020 APA,保留所有权利)。不一致的传送产生的误差比部分一致的传送产生的误差大,部分一致的传送产生的误差比行走大,反映了平移和旋转自运动线索的重要性。此外,几何边界(房间墙壁或围栏)对于减轻与传送相关的空间认知成本是必要的,并且地标仅在几何边界的背景下才有帮助。(PsycInfo 数据库记录 (c) 2020 APA,保留所有权利)。并且地标仅在几何边界的情况下才有用。(PsycInfo 数据库记录 (c) 2020 APA,保留所有权利)。并且地标仅在几何边界的情况下才有用。(PsycInfo 数据库记录 (c) 2020 APA,保留所有权利)。
