Virtual avatars in the VR world can literally extend the body of a real person, e.g. wings and tails. In order to enhance the self-identity of such avatars, technology is needed to synchronize people's unconscious bodily movements, such as nonverbal expressions with emotions.
We developed a series of systems for expressing emotions in VR being, which is an extension of the human body using a brain wave interface, and developed the VR experience "Fairy Tail" as the experience. In "Fairy Tails", the user who has a new body with a tail in the VR world can learn to express natural emotions while moving through the story. It is also expected to positively affect the user's emotions. In the future, we will empirically verify that this kind of extended-expression of the VR body also extends the human's own emotions.
