Connecting strangers at a train station

In this paper we describe a virtual instrument or a performance space, placed at Høje Tåstrup train station in Denmark, which is meant to establish communicative connections between strangers, by letting users of the system create soundscapes together across the rails. We discuss mapping strategies and complexity and suggest a possible solution for a final instance of our interactive musical performance system. instrument becomes important in itself. This paper describes the authors main experiences with motion tracking, mapping strategies and sound designs from user tests in connection to the development of an interactive installation which takes place in Hoje Taastrup train station in Denmark.
