However, it is difficult for the user to experience the immersive virtual world in the real workplace, such as the design room or the conference room, because this type of display system requires a large space in order to install the screen. In this study, an invisible interface was developed for the immersive virtual world by integrating a transparent immersive projection display and cellular phone interface technologies. By using this system, the user in the real world can experience the high presence virtual world in an immersive environment. This system was applied to several fields of application, such as augmented reality and telecommunications.
