This paper describes a conference which linked several remote sites via a virtual environment so that the virtual audience could follow the presentations and interact with real presenters. The aim was to assess the feasibility of linking distributed virtual audiences to an ongoing conference event. Various types of data about the conference were gathered, such as participant observations, interviews and a survey of the audience, and analyzed. The main finding is that a number of `low tech' improvements could be made that could greatly enhance this type of virtual conferencing. A related finding is that the visual fidelity of the environment and of the avatars plays a lesser role than other factors such as audio quality. Given the paucity of research on how virtual conferencing can substitute for travel, plus the urgency of this topic for environmental reasons, a number of suggestions are made for the implementation of remote virtual conference participation.
