Existing studies have reported that the Full Body Ownership Illusion let users perceive a virtual body as our own body. It has also revealed the Proteus Effect that avatars’ appearance could affect user’s behavior, attitude and mental condition by inducing the Full Body Ownership Illusion. While many studies have focused on a humanoid avatar and its psychological effects, a previous study has reported that the Full Body Ownership Transfer can be induced even in the case of an animal avatar. In case of inducing the Full Body Ownership Transfer on an animal avatar, it can be expected to induce the psychological effect different from the one by a human avatar. Hence, this study examines a dragon avatar, which has impression of strong body and flight ability, can reduce the fear of height as the Proteus Effect by the Full Body Ownership Transfer. We carried out an experiment with some scenarios where a subject transformed into a dragon and flied into a height, comparing with operating a human avatar. The results showed that transforming into the dragon avatar can improve subjective score and physiological reaction for the fear of height.

In recent years, utilizing of an avatar is becoming popular at social VR contents. On the other hand, previous studies have reported that an avatar gives us positive effect in terms of the sense of immersion, a psychological effect, and the spatial awareness. Thus, we investigate how the avatar which a virtual body is used daily in social VR contents impact on the body ownership and the Quality of Experience, comparing with a realistic humanoid avatar. Our results show that the self-avatar can improve the sense of body ownership and the sense of immersion.

In recent years, a service industry is becoming to core of market economics. However, amount of worker are decreasing due to decreasing birthrate and aging population. To hire and train new human resources takes temporal, monetary and human cost. Previous studies have developed training simulator to resolve this issue. However, there is no research that focus on hospitality industry, as long as we know. Hence, we developed Virtual Reality training simulator for ground staff in airport. Specifically, on the basis of theory into practice, we developed a training simulator that can do training repeatable in a short time to maintain a motivation for a job. This system scans user’s facial expression and body movement, and convey to other user via an avatar. We were able to develop training simulator that gives us the feeling of a social presence from grand staff’s comments.

Since body ownership illusion is expected to enhance an individual ability and positive psychological effect, any existing studies investigated the cause of the body ownership illusion on a human-like avatar. However, few studies have been focused on an avatar whose figure is a non-humanlike, such as a bird. If the illusion on a bird avatar can be controlled, the user's feeling of the presence in virtual reality world and flying experience are expected to be enhanced. Thus, we conducted some experiments to investigate factors to elicit a sense of body ownership over a bird avatar. We evaluated how features of a bird, such as flying action, short body, and sounds of flapping, affected the sense of body ownership. Our findings suggest that a motion synchronization between a participant's body and an avatars' one induce a sense of body ownership. Furthermore, appearance of a bird increases user's immersion in flying experience. Avatar's appearance affects a sense of body ownership over a non-humanlike avatar.
