Pseudo physical contact is used for communication in virtual environments such as VRChat. We hypothesized that the pseudo physical contact could affect interpersonal impression and communication, and the interpersonal impression would be modulated by appearance of body or avatar type. To test these hypotheses, we performed a questionnaire survey for VRChat users (N=341). In results, interpersonal impression and communication difficulty were improved after the pseudo physical contact, but the avatar type did not modulate the interpersonal impression. These results suggest that the pseudo physical contact could improve the interpersonal impression and communication in virtual environments.

The COVID-19 pandemic has placed significant restrictions on experiments such as those using motion capture suits in the laboratory. On the other hand, the number of users of virtual reality (VR) social network services has been increasing due to the pandemic. Thus, we constructed a laboratory in VRChat, one of the VR social network services, where full-body ownership experiments can be conducted, and validated it. The subjects entered the experimental world in VRChat, changed into the experimental avatar, and participated in the experiment. The subject’s movements and the avatar were synchronized or asynchronized with 1-s delay. After 5-min ball reaching using the avatar, subjective evaluations were made regarding senses of body ownership, agency, and pseudo-haptics. In the synchronous condition, we obtained a stronger sense of body ownership, agency, and pseudo-haptic sensation than in the asynchronous condition, reproducing the results of previous studies. These results suggest that the laboratory in the public VR social network enables us to manipulate experimental conditions, and perform experiments on full-body illusion.
