Outline of Final Research Achievements

We aimed to investigate the relationship between body ownership and vection (visually induce self-motion perception). In a series of experiments, we measured latency and duration of perceived vection of observers while their body ownership and representation were modified using virtual reality. The duration of vection was significantly longer when an avatar was visible than invisible. The latency of vection was shorter and the duration of vection was longer when the avatar was synchronously moving with participants than when the avatar was asynchronously moving. Thus, it is suggested that the enhancement of body ownership facilitates vection perception and the diminishment of one's own body facilitates perception of environments.
