From proximity to accurate indoor localization for context awareness in mobile museum guides

Abstract

Proximity localization has become a common support in mobile-based personal CH fruition mobile assistants, notifying the visitor information about points of interest near to him but can hardly used to recognize its presence inside areas defining a semantic context in museums or expositions. In this paper we present an accurate indoor localization methodology relying on Bluetooth Low Energy technology that can be used to gently suggest to the user evidence of contextually coherent areas of interest around him. A localization accuracy as low as two meter has been measured and one meters limit evaluated during experimentation of a mobile guide in the Archeological Museum of Camarina, in province of Ragusa (Italy).
