Main consideration of our multi-user extension is the ease of transforming single-user virtual worlds to multi-user virtual worlds, as well as the conformity with any standard VRML97 browser. Furthermore, we present the EVE{\textquoteright} s communication platform, which can be used in order to support Collaborative Virtual Environments (CVEs). Main issues regarding the effective network communication as well as the initialization of the 3D scene are discussed in this paper.}, author = {Christos Bouras and Thrasivoulos Tsiatsos and D Psaltoulis and C Psaroudis} } @conference {2762, title = {An Educational Community Using Collaborative Virtual Environments}, booktitle = {1st International Conference on Web-based Learning, Hong Kong, China}, year = {2002}, month = {17 - 19 August}, pages = { 180 - 191}, abstract = {The use of Collaborative Virtual Environments in e-learning is one of the most promising uses of the virtual reality technology. While a lot of research has been done in the area of collaborative virtual environments corresponding to the sharing of events, very little research has been done on specific services and functionality. However both the requirements and the kind of the offered services affect significantly the design of a system. In this paper we present an Educational Community to support e-learning services using Collaborative Virtual Environments from both the technical and functional point of view.}, author = {Christos Bouras and Thrasivoulos Tsiatsos and D Psaltoulis and C Psaroudis} } @conference {2790, title = {A Platform for Sharing Educational Virtual Environments}, booktitle = {9th International Conference on Software, Telecommunications and Computer Networks (SoftCOM 2001) Split, Dubrovnik (Croatia) Ancona, Bari (Italy), Vol II}, year = {2001}, month = {9 - 12 October}, pages = { 659 - 666}, abstract = {In recent years, a lot of work has been done on multi-user virtual environments. This work led to platforms that aim to support 3D virtual communities. However, little research has been done on specific services and functionality, which affect significantly the design of a system. The growing need for communication, visualisation and organisation technologies in the field of e-learning environments, has led to the application of virtual reality and the use of multi-user real-time communication platforms to support these needs. In this paper we present the design and implementation of a platform, suitable for educational virtual environments. Apart from the platform itself, we present the technological choices, a new method for sharing virtual environments and a new protocol for educational virtual environments.}, author = {Christos Bouras and Thrasivoulos Tsiatsos and D Psaltoulis and C Psaroudis} }
