静态的，眼睛高度缩放的信息在感知通过性和引导运动通过孔的作用是很好的建立。然而，眼高缩放信息并不是关于尺寸和通过性的视觉信息的唯一来源。在这项研究中，我们测试了另外两种信息来源的充分性，这两种信息来源都只对移动的观察者可用（即，是动态的）并以固有的、身体缩放单位指定孔径大小。该实验是在一个沉浸式虚拟环境中进行的，通过头戴式显示器进行单目观察。受试者穿过障碍物之间的狭窄开口，必要时旋转肩膀，同时跟踪头部和肩膀的位置。这项任务是在三个虚拟环境中进行的，这三个虚拟环境在眼高缩放信息的可用性和两个动态信息源方面有所不同。分析的重点是受试者通过光圈时肩部旋转的时间和幅度，以及行走速度和碰撞次数。受试者成功地定时并适当地缩放肩部旋转的幅度，以适应所有三种条件下的孔。这些发现表明，视觉信息以外的眼高缩放信息可以用来引导运动通过孔。
The role of static, eyeheight-scaled information in perceiving the passability of and guiding locomotion through apertures is well established. However, eyeheight-scaled information is not the only source of visual information about size and passability. In this study, we tested the sufficiency of two other sources of information, both of which are available only to moving observers (i.e., are dynamic) and specify aperture size in intrinsic, body-scaled units. The experiment was conducted in an immersive virtual environment that was monocularly viewed through a head-mounted display. Subjects walked through narrow openings between obstacles, rotating their shoulders as necessary, while head and shoulder position were tracked. The task was performed in three virtual environments that differed in terms of the availability of eyeheight-scaled information and the two dynamic sources of information. Analyses focused on the timing and amplitude of shoulder rotation as subjects walked through apertures, as well as walking speed and the number of collisions. Subjects successfully timed and appropriately scaled the amplitude of shoulder rotation to fit through apertures in all three conditions. These findings suggest that visual information other than eyeheight-scaled information can be used to guide locomotion through apertures.
