Virtual Reality(VR) has attracted a great deal of attention in various contents fields by providing users with a presence experience and enabling users to directly perform their activities. Immersion in VR means to form a sense of reality and belief in the virtual world by playing a role with a new identity acquired in an empathetic manner away from oneself. In order to realize the immersive environment pursued by virtual reality, the convergence of human emotions and perception is essential. This cannot occur by simply perceptual immersion through physical stimulation. It can only occur when psychological immersion occurs together. However, research and development to increase the immersion of virtual reality focuses on the approach through sensory stimulation, such as visual, auditory, and tactile sense, and research and interest in psychological immersion is relatively inactive. An important feature of virtual reality is the interface between humans and computers that allows the users to directly control and interact with the virtual environment. The user can enhance the psychological immersion feeling by utilizing the natural interface with the virtual environment.
