This paper presents the results of the BT-funded `Inhabiting the Web" project which conducted a series of twenty virtualmeetings using the MASSIVE virtual reality teleconferencing system between five universities and BT Laboratories. The aimsof the project were, firstly, to assess the characteristics of the network traffic generated by MASSIVE and, therefore, byextension, the network traffic generated by other peer-to-peer unicast-based collaborative virtual environments, and,secondly, to...

    • ...Greenhalgh, Bullock, Tromp, and Benford (1997) have developed network traffic analysis, but this method addresses the volume and type of interaction between users based on a computational analysis of the network traffic generated; yet this computational analysis in itself cannot provide a detailed insight into the causal relationships between the acts of the CVE users...

    • ...Finally, the spatial parser functionality may be used similarly as the proximity functionality in CVE [7] to provide ongoing calculations of the objects that given specific measures of aura, focus and nimbus relative to a user’s camera will be rendered, activated or the like...

    • ...Previous trials had shown the importance of using high-quality audio input devices, capturing only what people say and not the background noise of the laboratory, if any meaningful analysis of the audio network trafé c was to be made (Greenhalgh, Bullock, Tromp, & Benford, 1997)...

    • ...will we consider a composite a stack if the distance from the top element to the next element is hundreds of measurement units? To solve this problem we are implementing spatial parsing with inspiration from the concepts of aura and nimbus [14] which originally were used to only render a representation of the parts of the hypermedia structure, which are sufficiently close to the user's "camera"...
    • ...We are currently experimenting with various ways of supporting implicit spatial structures inspired by the CVE aura [14] concept, where objects in the workspace may be interpreted as members of the same composite if they have certain level of overlap between their auras...
