The paper presents a case study developed during the Vespucci Summer School for Geographic Information Science in 2003. The author’s team proposed an innovative solution for guided tours in the city of Florence solving the problem of cutting the costs of travel guides and providing high added value services cheap and flexible. CICER1 applies all the research topics covered during the Location Based Services module of the Vespucci Summer School, involving mobile technologies and positioning systems. The approach used is practical and lead by the technical feasibility of CICER1. The author introduces the concepts of Location Based Services, Point of Interest and Portable Digital Assistants with a focus on their combined use to create a mobile localisation system that provides targeted real time geographic information to pedestrian tourists in an urban environment.
