“…There are certainly important aspects of CVEs that still need further work: for example, the avatars in current CVEs tend to be limited in terms of their expressive capabilities, leading to crucial weaknesses such as a lack of assurance, understanding, and attention cues (Ståhl, 1999). However, we believe that continuing research into the nature of human-to-human communication, both conscious and unconscious, in conjunction with continuing CSCW research in the areas of work collaboration, intuitive and non-intrusive interfaces, will gradually solve these issues.…”

Collaborative Virtual Environments to Support Communication and Community in Internet-Based Distance Education

Executive SummaryIn this paper we discuss the use of modern information and communication technologies for distance education (DE) purposes. We argue that current technologies and implementations do not adequately support the key concepts of communication and community that many practitioners believe to be important, particularly if modern pedagogies such as constructivism are to be supported. We propose that collaborative virtual environments (CVEs), which are computer-enabled, distributed virtual spaces or places in which people can meet and interact with others, with agents and with virtual objects, are appropriate tools for improving DE. We discuss the current developments in the areas of CVEs in particular and in computer supported co-operative work (CSCW) in general. We also note those areas in which the majority of CVEs implemented to date have not reached their full potential for DE support, discuss current thought regarding online community, and outline a proposed CVE-based system for DE. The architecture of a CVE should be based on the pedagogical requirements of the community and include three distinct types of virtual space: collaborative zones, common student campus, and lecture rooms. With proper design, a CVE should greatly assist the development of a productive learning community in which students' social, academic, and collaborative needs are met.

“…In contrast to desktop systems, IPTs are not as limited in their support for non-verbal communication and naturalness of object interactions [Ståhl 1999;Kjeldskov 2001;Robinson et al 2001]. The body movement is continuously tracked (usually just head and dominant hand), allowing both conscious and subconscious non-verbal communication to be captured and mapped onto the tracked person's avatar, as well as interaction with virtual objects.…”

Many teamwork tasks require a close coupling between the interactions of members of a team. For example, intention and opinion must be communicated, while synchronously manipulating shared artefacts. In face-to-face interaction this communication and manipulation is seamless. Transferring the straightforwardness of such collaboration onto remote located teams is technologically challenging. This survey paper explains why immersive collaborative virtual environments (CVE) suit such tasks. The effectiveness of application of this technology depends on a complex set of factors that determine the efficiency of collaboration. We examine these factors and their interrelationships within the framework of a taxonomy focussed on supporting closely-coupled collaboration using immersive CVEs. In particular we compare the impact of display configurations from distinct aspects within the interaction metaphors: look-in, reach-in and step-in.

“…One example for theses world-widely spread research activities was the former Europe ACTS project COVEN who demonstrated the benefits of the SVTE concept by a networked business game VR application in 1997 [26]. Later approaches were more and more focused on a seamless integration of 2D video images or even 3D video avatars into CVE's to increase realism [27] [28]. Some of these approaches were driven by the MPEG-4 multimedia standard that offers new powerful coding and composition tools for such purposes [13] [29].…”

Videoconferencing is going to become attractive for geographically distributed team collaboration, specifically to avoid travelling and to increase flexibility. Against this background this paper presents a next generation system -a 3D videoconference providing immersive tele-presence and natural representation of all participants in a shared virtual meeting space to enhance quality of human-centred communication. This system is based on the principle of a shared virtual table environment, which guarantees correct eye contact and gesture reproduction. The key features of our system are presented and compared to other approaches like tele-cubicles. Furthermore the current system design and details of the real-time hardware and software concept are explained.
