We developed a bed-style haptic display that provides weight sensation to large-area of the user's body. The system is composed of motors, belts, cushion and quilt to press and swing the user lying in bed. It is one type of the whole-body haptic interface, characterized by the presentation of low-frequency, multi degrees-of-freedom force. The system can enrich audio visual experience by several ways, such as expressing horrific ghost sitting on the user as an entertainment contents, or presenting remote relative's existence as a tele-communication tool. Overall, the system change the bed into a new medium in which immersive contents are truly presented immersively.
