摘要： A user wears a virtual reality mask (VR mask) (100) and then watches a virtual reality image. The VR mask (100) blocks light incident from the outside. When the user wears the VR mask (100), the user cannot discover an obstacle (500) positioned outside the VR mask (100). The user may collide with the obstacle (500) and may be injured by the obstacle (500). Accordingly, in order to prevent injury to the user who uses the VR mask (100), it is necessary to make the user recognize the obstacle (500) positioned outside the VR mask (100). In order to recognize an obstacle, a virtual reality image and the obstacle may be displayed together, or the amount of light incident from the outside may be adjusted.
