Abstract
Location-aware smart spaces fuse information from a location system and a computational world model to make contextual inferences. To date, research has concentrated on the development of cheap, realisable, accurate location systems. Comparatively little research has addressed the issue of how to maintain the world model so crucial to contextual interferences. This paper details a framework to autonomously monitor a world model (the computer-readable representation of the world) for fine-grained location systems by regularly determining its consistency with the real world. It deals with the interpretation of information that can be derived from positioning systems and the construction of a general grid-based method for evaluating consistency between real and virtual worlds. Results to date are presented using location data from an extensive deployment of a location system, before future avenues of research are identified.
