基于身体的缩放的概念表明，我们的身体及其动作能力用于扩展环境的空间布局，我们提出了四个支持这一观点的研究。但是，要测试这一点的对象，必须能够操纵感知者的大小和/或尺寸，这在现实世界中很难克服此限制。在一系列实验中操纵参与者完全跟踪的虚拟手的尺寸，以研究其对虚拟对象的尺寸和形状的影响，我们证明了个人对虚拟对象大小的估计根据他们的虚拟手的大小，沿着基于身体的缩放假设一致为基于身体的方法提供了支持空间布局的缩放的支持，他们还展示了虚拟物体对虚拟环境感知的影响。
The notion of body-based scaling suggests that our body and its action capabilities are used to scale the spatial layout of the environment. Here we present four studies supporting this perspective by showing that the hand acts as a metric which individuals use to scale the apparent sizes of objects in the environment. However to test this, one must be able to manipulate the size and/or dimensions of the perceiver’s hand which is difficult in the real world due to impliability of hand dimensions. To overcome this limitation, we used virtual reality to manipulate dimensions of participants’ fully-tracked, virtual hands to investigate its influence on the perceived size and shape of virtual objects. In a series of experiments, using several measures, we show that individuals’ estimations of the sizes of virtual objects differ depending on the size of their virtual hand in the direction consistent with the body-based scaling hypothesis. Additionally, we found that these effects were specific to participants’ virtual hands rather than another avatar’s hands or a salient familiar-sized object. While these studies provide support for a body-based approach to the scaling of the spatial layout, they also demonstrate the influence of virtual bodies on perception of virtual environments.
