现实世界和虚拟环境中的空间知觉研究表明，身体(例如手)在感知世界的尺度方面发挥着作用。然而，很少有研究仔细研究虚拟身体部位的大小变化如何影响对动作能力和空间布局的判断。在这里，我们质疑改变虚拟脚的大小是否会影响对跨过的判断和对缺口宽度的估计。参与者认为他们的虚拟虚拟脚是大是小，并判断他们跨过缺口的能力和虚拟世界中显示的缺口的大小。脚的大小影响了负担能力判断和大小估计，以至于那些虚拟脚变大的人估计他们可以跨过更大的差距，差距的程度更小。缩脚会让人感觉跨过缺口的能力降低，估计的宽度也会变小。研究结果表明，人们使用视觉感知的脚的大小来扩展虚拟空间。无论脚的大小如何，参与者都感觉自己拥有在虚拟世界中渲染的脚。看到无实体但有运动跟踪的虚拟脚会影响空间判断，这表明呈现一个被跟踪的身体部分足以对感知产生类似的影响，就像过去观察到的完全位于同一位置的虚拟自我化身或其他身体部分的存在一样。
Spatial perception research in the real world and in virtual environments suggests that the body (e.g., hands) plays a role in the perception of the scale of the world. However, little research has closely examined how varying the size of virtual body parts may influence judgments of action capabilities and spatial layout. Here, we questioned whether changing the size of virtual feet would affect judgments of stepping over and estimates of the width of a gap. Participants viewed their disembodied virtual feet as small or large and judged both their ability to step over a gap and the size of gaps shown in the virtual world. Foot size affected both affordance judgments and size estimates such that those with enlarged virtual feet estimated they could step over larger gaps and that the extent of the gap was smaller. Shrunken feet led to the perception of a reduced ability to step over a gap and smaller estimates of width. The results suggest that people use their visually perceived foot size to scale virtual spaces. Regardless of foot size, participants felt that they owned the feet rendered in the virtual world. Seeing disembodied, but motion-tracked, virtual feet affected spatial judgments, suggesting that the presentation of a single tracked body part is sufficient to produce similar effects on perception, as has been observed with the presence of fully co-located virtual self-avatars or other body parts in the past.
