Similarly, mixed reality systems use some of the same technologies as ‘traditional’ collaborative virtual environments and virtual worlds, but they are increasingly coupled and interconnected with other media in a way that we usually associate with ubiquitous computing systems. The context of use of a system, and context as modelled within that system, may consist of a heterogeneous combination of both new and old media. This paper uses theoretical work on the interdependence and interpretation to discuss such coupling among heterogeneous media. Our long–term aim is better understanding of the design and use of such systems, and better design practice consistent with theory and studies of user experience. </ABSTRACT></RECORD></RECORDS></XML>
