-This paper describes the development of interface for navigating the deaf-blind with a wearable computer and the development of the positioning system using active RFID tags. The former is designed to communicate with the computer by finger braille, which is one of the communication methods of the deaf-blind. We made two prototypes, vibration motor type and solenoid type. And the latter was chosen in order to navigate the deaf-blind smoothly in the place where other positioning systems cannot work. We evaluated the system which consists of the wearable finger braille interface and position detection using RFID tags. We report this wearable interface and RFID tags positioning system.
