Human bodies influence the owners' affect through posture, facial expressions, and movement. It remains unclear whether similar links between virtual bodies and affect exist. Such links could present design opportunities for virtual environments and advance our understanding of fundamental concepts of embodied VR. An initial outside-the-lab between-subjects study using commodity equipment presented 207 participants with seven avatar manipulations, related to posture, facial expression, and speed. We conducted a lab-based between-subjects study using high-end VR equipment with 41 subjects to clarify affect's impact on body ownership. The results show that some avatar manipulations can subtly influence affect. Study I found that facial manipulations emerged as most effective in this regard, particularly for positive affect. Also, body ownership showed a moderating influence on affect: in Study I body ownership varied with valence but not with arousal, and Study II showed body ownership to vary with positive but not with negative affect.

情感化身：虚拟身体的情感和所有权之间的相互作用

人体通过姿势、面部表情和动作来影响主人的情感。目前尚不清楚虚拟身体和情感之间是否存在类似的联系。这样的链接可以为虚拟环境提供设计机会，并促进我们对具体 VR 基本概念的理解。使用商品设备在实验室外进行的初始受试者间研究向 207 名参与者展示了七个与姿势、面部表情和速度相关的虚拟化身操作。我们使用高端 VR 设备对 41 名受试者进行了基于实验室的受试者间研究，以阐明情感对身体所有权的影响。结果表明，一些化身操作可以巧妙地影响影响。研究我发现面部护理在这方面最有效，尤其是在积极影响方面。还，
