Virtual reality systems typically allow users to physically walk and turn, but virtual environments (VEs) often exceed the available walking space. Teleporting has become a common user interface, whereby the user aims a laser pointer to indicate the desired location, and sometimes orientation, in the VE before being transported without self-motion cues. This study evaluated the influence of rotational self-motion cues on spatial updating performance when teleporting, and whether the importance of rotational cues varies across movement scale and environment scale. Participants performed a triangle completion task by teleporting along two outbound path legs before pointing to the unmarked path origin. Rotational self-motion reduced overall errors across all levels of movement scale and environment scale, though it also introduced a slight bias toward under-rotation. The importance of rotational self-motion was exaggerated when navigating large triangles and when the surrounding environment was large. Navigating a large triangle within a small VE brought participants closer to surrounding landmarks and boundaries, which led to greater reliance on piloting (landmark-based navigation) and therefore reduced-but did not eliminate-the impact of rotational self-motion cues. These results indicate that rotational self-motion cues are important when teleporting, and that navigation can be improved by enabling piloting.

通过虚拟环境进行传送：路径比例和环境比例对空间更新的影响。

虚拟现实系统通常允许用户实际行走和转弯，但是虚拟环境（VE）通常超出可用的行走空间。传送已成为一种常见的用户界面，借此，用户无需移动就可以在移动前将激光指示器对准VE，以指示VE中所需的位置，有时还指示方向。这项研究评估了旋转自我提示对传送时空间更新性能的影响，以及旋转提示的重要性是否随运动尺度和环境尺度而变化。参与者通过在指向未标记的路径原点之前沿两个出站路径分支传送来完成三角形完成任务。旋转自运动减少了运动尺度和环境尺度所有级别的总体误差，尽管它也为旋转不足带来了一些偏差。导航大三角形时以及周围环境很大时，旋转自运动的重要性被夸大了。在一个小的VE中导航一个大三角形可使参与者更接近周围的地标和边界，这导致人们更多地依赖飞行员（基于地标的导航），因此减少了但并未消除旋转自运动提示的影响。这些结果表明旋转自动运动提示在传送时很重要，并且可以通过启用导航来改善导航。在一个小的VE中导航一个大三角形可使参与者更接近周围的地标和边界，这导致人们更多地依赖飞行员（基于地标的导航），因此减少了但并未消除旋转自运动提示的影响。这些结果表明旋转自动运动提示在传送时很重要，并且可以通过启用导航来改善导航。在一个小的VE中导航一个大三角形可使参与者更接近周围的地标和边界，这导致对飞行员的更多依赖（基于地标的导航），因此减少了但并没有消除旋转自运动提示的影响。这些结果表明旋转自动运动提示在传送时很重要，并且可以通过启用导航来改善导航。
