Abstract

In this paper we make use of automatically generated logs of user activity from 6 meetings held using the MASSIVE-1 virtual reality tele-conferencing system to determine a number of characteristics of user movement and world transition. These results are applied to a consideration of four issues for CVE system design and resource requirements: the amount of network bandwidth and computation required to handle movement within worlds


the degree of look-ahead required when moving


whether world transitions by groups of participants could benefit from special handling (e.g. some form of multicast state-transfer)


and whether caching of world state would be useful in these contexts. In each case the implications are quantified for the meetings analysed.
