AI 中文摘要
虚拟现实（VR）技术能让用户产生虚拟身体是自己身体的错觉（即身体所有权错觉）。以往研究聚焦拟人化方面，探讨用户虚拟身体视觉真实感对VR中身体所有权感的影响，而虚拟人视觉真实感的另一要素——照片真实感在身体所有权错觉背景下未被系统研究。因此，研究虚拟手的渲染风格对身体所有权感的影响，假设其受虚拟环境渲染风格影响。此外，因现有研究证据不一致，故考察照片真实感对临场感的影响。为此进行了3×3混合设计远程VR实验（N = 117），考虑虚拟手和环境的渲染风格并分析问卷主观数据。结果表明，虚拟手的渲染风格及其与环境渲染风格的一致性均不影响身体所有权感，但虚拟环境渲染得越具照片真实感，临场感越强。研究结果表明虚拟身体真实感的不同维度对身体所有权感的影响不同，凸显应用合适的真实感分类以更深入理解虚拟身体的身体所有权错觉的重要性。
英文摘要
Virtual reality (VR) technology allows users to feel a virtual body as if it was their own (i.e., body ownership illusion). Previous studies have explored how the visual realism of the user's virtual body influences the sense of body ownership in VR, focusing on the aspect of anthropomorphism. However, the effect of photorealism, another element that characterizes the visual realism of a virtual human, has not been systematically examined in the context of body ownership illusion. Therefore, we investigate the effect of the rendering style of virtual hands on the sense of body ownership, hypothesizing that the effect is affected by the rendering style of the virtual environment. In addition, we examine the effect of photorealism on presence (i.e., the sense of being there), as existing studies have offered inconsistent evidence. To this aim, we conducted a 3 x 3 mixed-design remote VR experiment (N=117) that factored in the rendering styles of both the virtual hand and the environment and analyzed the subjective data from the questionnaire. The results suggest that neither the rendering style of virtual hands nor the consistency of the rendering style between the virtual hand and the environment influenced the sense of body ownership. Nevertheless, the more photorealistically the virtual environment was rendered, the stronger the presence. Our results indicate that different dimensions of virtual body realism affect the sense of body ownership differently, thereby highlighting the importance of applying a suitable classification of realism to understand the body ownership illusion for virtual bodies more in depth.
