Rendezvous enhancement for conference support system based on RFID

RFID attracts attention as a useful device in location-aware application. SPEARS WG of WIDE Project had already developed a system (2003), which uses RFID devices as a sensor of human\´s location. Purpose for this system is to provide the service based on a user\´s location in a conference. In this system, the model in which location of user is gathered and provided for each user was adopted. This paper describes several areas of problems and improvements in our latest implementation. The following functions were implemented by the addition of a system called "Area-d": 1) provide a service tied with a location, and 2) provides users\´ communication rendezvous service. These functions are able to add to the existing system without altering the existing model. This paper describes a location-oriented data processing model and applications.
