论文摘要
这项研究旨在更好地理解在VR中受到抚摸的情感和生理相关性，具体取决于提供的多感官反馈的类型以及触及虚拟虚拟体的虚拟表示的动画或无生命的性质。我们评估了在VR中的愉悦，唤醒，体现和触摸的幻觉如何受到仅包含视觉反馈与视觉刺激条件相比的影响，在这些情况下，参与者除了看到Afcatar或羽毛抚摸其虚拟身体外，还可以感知到同样的一致性中性超声触觉刺激或真实的Interpersernal或真实的Interpersernal触摸。我们发现，与仅基于视觉反馈的条件相比，基于超声或真实的人际触摸的Visuotactile反馈是基于超声或真实的人际关系的反馈，可以增强在虚拟体中被情感触摸和体现的幻觉。但是，与其他条件相比，真正的人际关系导致了最强的行为和情感反应。此外，与虚拟羽毛相比，当女性化身触摸时，唤醒和撤回抚摸手的愿望最高。女性参与者报告说，与男性相比，在VR中受到抚摸的幻想。总体而言，这项研究促进了VR中情感感受的情感和生理影响的知识。
This study aims to better understand the emotional and physiological correlates of being caressed in VR depending on the type of multisensory feedback provided and the animate or inanimate nature of the virtual representation that touches an embodied virtual body. We evaluated how pleasure, arousal, embodiment, and the illusion of being touched in VR were influenced by the inclusion of only visual feedback compared to visuotactile stimulation conditions, where participants, in addition to seeing an avatar or feather caressing their virtual bodies, also perceived congruent mid-air ultrasonic tactile stimulation or real interpersonal touch. We found that visuotactile feedback, either based on ultrasound or real interpersonal touch, boosts the illusion of being affectively touched and embodied in a virtual body compared to conditions only based on visual feedback. However, real interpersonal touch led to the strongest behavioral and emotional responses compared to the other conditions. Moreover, arousal and the desire to withdraw the caressed hand was highest when being touched by a female avatar compared to a virtual feather. Female participants reported a stronger illusion of being caressed in VR compared to males. Overall, this study advances knowledge of the emotional and physiological impact of affective touch in VR.
