Abstract

How does the appearance of a virtual hand affect own-body perception? Previous studies have compared either two or three hand models at a time, with their appearances limited to realistic hands and abstract or simple objects. To investigate the effects of different realisms, render styles, and sensitivities to pain on the virtual hand illusion (VHI), we conduct two studies in which participants take on controllable hand models with six distinct appearances. We collect questionnaire data and comments regarding responses to impacts and threats to assess differences in the strength of the VHI. Our findings indicate that an illusion can be created for any model for some participants, but that the effect is perceived weakest for a non-anthropomorphic block model and strongest for a realistic human hand model in direct comparison. We furthermore find that the responses to our experiments highly vary between participants.
需要帮忙吗?:外观如何影响虚拟手的错觉
虚拟手的外观如何影响自己的身体感知?之前的研究一次比较了两个或三个手部模型,这些模型的外观仅限于真实的手和抽象或简单的物体。为了研究不同的现实主义、渲染风格和对疼痛的敏感性对虚拟手错觉(VHI)的影响,我们进行了两项研究,参与者采用具有六种不同外观的可控手模型。我们收集问卷数据和对影响和威胁的反应的意见,以评估VHI强度的差异。我们的研究结果表明,对于一些参与者来说,任何模型都可以产生错觉,但在直接比较中,非拟人化的积木模型的效果最弱,而逼真的人手模型的效果最强。我们进一步发现,参与者对我们实验的反应差异很大。
