VR空間で2人同時操作を行う4本腕アバターに対する自己身体感についての検討

抄録

Having a self-body recognition for avatars with human augmentation is important to improve the user experience. In this study, we examine the self-body recognition for a four-armed avatar operated by two people. The arm directly operated by the subject is called the main arm, and the arm operated by another subject (the experimenter) is called the subarm. Questionnaires and instantaneous heart rate were used as indices of self-body recognition. The heart rate results showed that the subject’s self-body recognition for the subarm emerged when the subarm moved to meet the subject’s goal. This suggests that it is important for the extended body part of a human augmentation avatar to move in the manner that shares the intention with the subject during operation to recognize the avatar’s body as their own.
