After two years of work, we are presenting the main features of our approach and results: our driving applications, the main components of our technical investigations, and our experimental activities. With different citizen and professional application scenarios as driving forces, COVEN is exploring the requirements and supporting techniques for collaborative interaction in scalable CVEs. Technical results are being integrated in an enriched networked VR platform based on the dVS and DIVE systems. Taking advantage of a dedicated Europe-wide ISDN and ATM network infrastructure, a large component of the project is a trial and experimentation activity that should allow to build up a comprehensive understanding of the technical network requirements of such systems along with their usability issues and human factors aspects.

We replicated their study, adding real walking as a third condition.

It introduces the idea of "stacking depth", that is, where a participant can simulate the process of entering the virtual environment while already in such an environment, which can be repeated to several levels of depth. An experimental study including 24 subjects was carried out. Half of the subjects were transported between environments by using virtual Head-mounted displays, and the other half by going through doors. Three other binary factors were: whether or not gravity operated, whether or not the subject experienced a virtual precipice, and whether or not the subject was followed around by a virtual actor.
