The Effects of Group Collaboration on Presence in a Collaborative Virtual Environmentis produced different levels of collaboration and interaction between the two VEs. Personal presence was measured subjectively, using a questionnaire developed by Slater .. We have developed a co-presence questionnaire which assesses the levels of co-presence subjectively. A collaboration questionnaire has also been developed.

Developing Effective Navigation Techniques in Virtual 3D Environmentsing/learning environments for children of elementary schools are implemented and evaluated. The simple control of relevant parameters, made possible by the model, can be transferred easily to other ranges of application.

Quality of Service Management for a Media-Enhanced Virtual Meeting Placeessing speed, and workload, have severe effects on the usability, performance and effectiveness of such an application. For this reason a Quality of Service (QoS) management is needed to adapt the application, and maintain usability and effectiveness at the highest level possible, under varying resource conditions.
