Shared space: An augmented reality approach for computer supported collaborative work

Abstract

Virtual Reality (VR) appears a natural medium for three-dimensional computer supported collaborative work (CSCW). However the current trend in CSCW is to adapt the computer interface to work with the user's traditional tools, rather than separating the user from the real world as does immersive VR. One solution is through Augmented Reality, the overlaying of virtual objects on the real world. In this paper we describe the Shared Space concept -the application of Augmented Reality for three-dimensional CSCW. This combines the advantages of Virtual Reality with current CSCW approaches. We describe a collaborative experiment based on this concept and present preliminary results which show that this approach may be better for some applications. © Springer-Verlag London Ltd.
