Collaborative virtual environments

Abstract
This paper introduces a spatial model,of interaction which aims to support groups of people ,in using ,their natural communication ,skills in distributed virtual environments. First, we outline our motivation for undertaking this work in terms,of the social significance of space,in supporting,co-operative work. Next, we summarise the model's main concepts, namely aura, awareness, focus, nimbus, adapters and boundaries. Following this, we describe routes to implementing the model. The first is an approach suited to realising the model as an application of existing VR platforms. The second is ageneral implementation of the model, based on its own specially tailored distributed architecture. Finally, we present our initial observations from use in the laboratory setting and outline issues for future work.To appear in Proceedings VRST'94, Singapore, August 1994, ACM Press.
