1 {ryuhei-t, kanbara, PDA Nara Palace Site Navigator Mobile Tour Guide System Using Multimedia Contents Ryuhei TENMOKU Masayuki KANBARA and Naokazu YOKOYA Graduate School of Information Science, Nara Institute of Science and Technology Takayama-cho, Ikoma-shi, Nara, Japan {ryuhei-t, kanbara, Abstract Many human navigation systems which present location-based information to mobile device users have been developed in recent years. We have already developed a wearable tour guide system which presents location-based tour guide information using augmented reality techniques. In this research, we try to improve the previous system into a new human navigation system "Nara Palace Site Navigator" for users of multi devices. The proposed system can present tour guide information according to the specifications of the user s devices: wearable computer, personal digital assistant (PDA), and cellular phone. This paper describes the experiments using the proposed system in the Nara palace site to show the feasibility of the proposed system.
