"UBWALL", ubiquitous wall changes an ordinary wall into the smart ambience

This paper describes how smart ambience improves information services. For information services in a public space, UBWALL is developed named after "ubiquitous wall", which has a large display and eight-series of built-in RFID reader/writer so that people can get individual information appropriately by using IC cards (RFID cards) or mobile terminals. UBWALL is usually installed in a public space for the purpose of advertisements or directory services, where people can see both the public and personalized information at a time identifying user profile by touching with RFID cards. UBWALL was exhibited in several exhibitions and we confirmed its effectiveness and availability as a new system for information services.
