在本文中，我们研究的视听体验在虚拟现实（VR）服务的背景下，使沉浸在虚拟环境（VE）和化身作为一个商店的工作人员之间的用户更有效的互动。通过利用VE经验的特点，我们发现这种不切实际的虚拟形象的视觉和听觉位置之间的关系呈现给用户变量，而不是均匀地呈现在同一位置的影响。在这项研究中，我们进行了一项实验，调查如何之间的声音和视觉图像的位置偏差可以容忍在VE，位置偏差的人际距离的化身，和操纵的印象的化身偏离声音图像从视觉图像的可能性。在实验中，我们准备了一个类似于VE商店的空间，并与16名性别平衡的参与者和六种类型的化身进行了接近实验。通过利用实验中显示的视觉信息优于听觉信息的优势，我们构建了一个人际关系的情况下，一个化身扮演的角色，商店的工作人员，其中只有声音图像侵入用户的个人空间，我们调查了用户的印象化身。我们还调查了用户对头像的印象。我们在允许位置差异的实验条件下发现了以下两个现象：1）即使允许位置差异，也会引起类似“恐怖谷”的现象，导致融洽度下降;以及2）在当声音图像比视觉图像更接近参与者时允许位置差的条件下，当化身扮演商店工作人员的角色时，这种融洽感更强。这种现象类似于“脚在门”现象，其中小的无意识同意（即，允许声像侵入一个人的个人空间）导致对另一个人的评价的改进（即，与另一个人的关系）。在本文中提出的技术，如声音和视觉图像之间的位置差异，显着提高价值的服务经验，通过与他人在虚拟环境中的互动。
In this paper, we examine the audiovisual experience in virtual reality (VR) service context that enables a more effective interaction between a user immersed in a virtual environment (VE) and an avatar as a store staff. By utilizing the characteristics of VE experiences, we find the effects of this unrealistic relationship between the visual and auditory positions of the avatar presented to the user variable rather than uniformly presented in the same position. In this study, we conducted an experiment to investigate how the positional deviation between the sound and visual images can be tolerated in VE, the effect of positional deviation on the interpersonal distance to the avatar, and the possibility of manipulating the impression of the avatar by deviating the sound image from the visual image. For the experiment, we prepared a space resembling a VE store and conducted proximity experiments with 16 gender-balanced participants and six types of avatars. By utilizing the superiority of visual information over auditory information revealed in the experiments, we constructed an interpersonal situation with an avatar playing the role of store staff in which only the sound image intruded into the user’s personal space, and we investigated users’ impressions of the avatar. We also investigated users’ impressions of the avatar. We found the following two phenomena in the experimental conditions where the positional difference was allowed: 1) Even when the positional difference was allowed, it caused an “uncanny valley”-like phenomenon that led to a decrease in rapport; and 2) In the conditions where the positional difference was allowed when the sound image was closer than the visual image to the participant, the rapport was greater with the avatar playing the role of the store staff. This phenomenon is similar to the “foot-in-the-door” phenomenon in which small unconscious consent (i.e., allowing a sound image to intrude on one’s personal space) leads to an improvement in the evaluation of the other person (i.e., the rapport with another person). The techniques proposed in this paper, such as the positional difference between the sound and visual images, significantly improve the value of the service experiences obtained through interaction with others in VE.
