The Impact of Body Posture on 3D Spatial Survey Knowledge in VR Simulated Microgravity Environment

With the advancement of aerospace and deep-sea exploration technology, humans are no longer constrained by gravity and maintain a vertical posture in various microgravity environments, thus expanding their activity range beyond the two-dimensional plane. Although previous studies have investigated the relationship between body posture and partial perception of environmental space, they predominantly focus on two-dimensional spaces and do not systematically analyze the impact of bodily perception posture on the representation of spatial global knowledge, the overview of survey knowledge. This study adapts the task paradigm for three-dimensional application and employs virtual reality (VR) technology to simulate microgravity environments, inducing full-body illusions. By systematically investigating the effects of different bodily perception postures on the representation of three-dimensional spatial survey knowledge from a first-person perspective, we aim to provide theoretical assistance and empirical support for the effectiveness of VR training and future human activities in three-dimensional spaces, facilitating the advancement of human-computer interaction. The related environment, data and conclusions of the experiments will be demonstrated and discussed in the full paper.
