As a new haptic device for daily use, a pillow-shaped haptic device using a pneumatic actuator, the Air-pillow telephone, is proposed. The Air-pillow telephone allows an intimate couple at a distance to mutually share the partner's sense of touch and presence as if they were together. We have developed a prototype system with an air bag driven by a piston-cylinder mechanism. The user's head motion affects the air pressure of the air bag and then its signal is bilaterally transmitted in real time via internet to actuate the partner's air pillow. This paper describes the Air-pillow telephone concept and application as well as implementation of the prototype system and experimental results on a commercial internet environment.
