Abstract

In a distributed shared synthetic environment with provisions for high quality 3D visualization and interaction, it is possible to implement a powerful variant of a rooms/space metaphor based on the concept of presence or proximity between participants in 3D space. This kind of model can be used as an interface between the user and the computer, for overview and control of applications, file systems, networks and other computer resources, as well as for communication and collaboration with other users in the networked environment. We model proximity with a geometric volume of the immediate surroundings, the aura, of the participant's representation in the synthetic environment. This proximity, or aura, is used to establish presence at meetings, to establish communication channels and to provide interaction.
