Here, virtual reality is discussed from the viewpoint of a media art. The works of an artist are a reflection of a given period and the consciousness of its people; virtual reality is considered to be one form of high technology that allows such expression. We seek to build a system where anyone can actively create an image they envision, allowing a sense of realism to be felt. Therefore, we need a human-like character that has a psychological make up, expresses emotions, is intelligent, and possesses its own personality. Neuro-baby, MIC and session character MUSE possess such realistic traits and communicate through a virtual reality system. We are currently researching the next step: Interactive Theater, a story that changes to correspond with emotions.media art
