The spatial knowledge representation of players movement in mobile outdoor gaming

This paper describes an innovative approach for developing a spatial knowledge representation based on the existence of multi tier spaces as a mental construction of human movement. The three "spaces" paradigm has been proposed to support the reasoning process in terms of sensing, symbolic, and social spaces. The spatial knowledge representation was implemented as a computational ontology in Protégé, and it has been applied to provide new insight about the actual behavioural patterns of players within a recreation site, accordingly to checkpoints and similar players´ interactions. This first experiment consisted of an educational game in Amsterdam using mobile phones and GPStechnology for 200 students having the age of 12-14. The results demonstrate that different types of inferences play a different role accordingly to what a recreational planner needs to infer, that is, the location of interactions among players and the environment.
