People navigation system in confined spaces

This paper describes the architecture of a navigation system for people that need to be guided through indoor environments, e.g., public buildings, hospitals, where navigation is very critical. The system has to provide both navigation and context aware information to people that may be in difficult emotive state as it happens to patients and visitors in a hospital. This system is under development within the POR/FESR Project EasyMob, funded by Friuli Venezia Giulia region of Italy. In this paper we will first present the EasyMob system approach and discuss requirements and challenges. Then, we will focus on the navigation technology and we will describe the solutions that have been developed.
