Our work investigates the influence of self-related cues in the design of virtual humans on body perception in virtual reality. In a $2\times 2$ mixed design, 64 participants faced photorealistic virtual humans either as a motion-synchronized embodied avatar or as an autonomous moving agent, appearing subsequently with a personalized and generic texture. Our results unveil that self-related cues through embodiment and personalization yield an individual and complemented increase in participants' sense of embodiment and self-identification towards the virtual human. Different body weight modification and estimation tasks further showed an impact of both factors on participants' body weight perception. Additional analyses revealed that the participant's body mass index predicted body weight estimations in all conditions and that participants' self-esteem and body shape concerns correlated with different body weight perception results. Hence, we have demonstrated the occurrence of double standards through induced self-related cues in virtual human perception, especially through embodiment.
我们的工作研究了自我相关线索在虚拟现实中设计虚拟人类对身体感知的影响。在一个 2×2 的混合设计中，64 名参与者面对的是逼真的虚拟人类，要么是运动同步的具身化身，要么是自主移动的代理，随后会出现个性化和通用的纹理。我们的结果表明，通过具身化和个性化的自我相关线索会导致参与者对虚拟人类的具身感和自我认同的个体和互补性增加。不同的体重修改和估计任务进一步表明，这两个因素都会影响参与者对体重的感知。进一步的分析表明，参与者的身体质量指数预测了所有条件下的体重估计，而参与者的自尊和身体形状担忧与不同的体重感知结果相关。因此，我们通过在虚拟人类感知中诱导自我相关线索证明了双重标准的存在，尤其是通过具身化。
