自己アバタの三人称視点操作を用いたself-distancing

抄録

Self-distancing is the method of adjusting the psychological distance from one’s own experience. Keeping a psychological distance from the issue affects how we address it. For example, people often devise more creative ideas for others’ problems than for their own problems. In this study, we employed virtual reality for supporting self-distancing. We developed a system that enables the user to operate his/her avatar from the third-person perspective by changing the user’s perspective out of the body. We conducted an experiment in which participants were asked to solve problems that require insight and creative thinking from either the first-person or third-person perspective (3PP). The results indicate that the 3PP increases users’ psychological distance from their experiences and brings greater insight. However, there was no significant difference in the number of ideas that users could devise. Based on these findings, we discuss the interface design required for incorporating self-distancing, regardless of users’ abilities and circumstances.
