当用户和自我化身的运动高度一致时，虚拟现实 (VR) 中化身的体现通常会更强。然而，当用户与虚拟环境交互时，两者之间的一对一映射并不总是理想的。在这些情况下，用户输入通常会导致没有物理真实性的不自然行为（例如，物体穿透虚拟身体，身体因撞击刺激而不动）。我们研究了在自我化身运动中添加物理校正如何影响体现。物理感知的自我化身保留了运动的物理意义，但引入了用户和自我化身的运动之间的差异，其偶然性是体现的决定因素。为了了解其影响，我们进行了一项实验室研究（n = 20），参与者在 VR 中与上半身的障碍物进行互动，无论是否进行物理校正。我们的结果表明，在主动和被动交互中，与无物理条件相比，物理响应的自我化身并没有损害具体化水平，而是改善了具体化。
Embodiment toward an avatar in virtual reality (VR) is generally stronger when there is a high degree of alignment between the user’s and self-avatar’s motion. However, one-to-one mapping between the two is not always ideal when user interacts with the virtual environment. On these occasions, the user input often leads to unnatural behavior without physical realism (e.g., objects penetrating virtual body, body unmoved by hitting stimuli). We investigate how adding physics correction to self-avatar motion impacts embodiment. Physics-aware self-avatar preserves the physical meaning of the movement but introduces discrepancies between the user’s and self-avatar’s motion, whose contingency is a determining factor for embodiment. To understand its impact, we conducted an in-lab study (n = 20) where participants interacted with obstacles on their upper bodies in VR with and without physics correction. Our results showed that, rather than compromising embodiment level, physics-responsive self-avatar improved embodiment compared to no-physics condition in both active and passive interactions.
