There are many definitions of the expression virtual environment (VE) in literature (in this monograph the terms virtual environment, environment, virtual world and world will be used indistinctly). Some definitions are highly restrictive while others are more open. Generally the restrictive approaches define virtual environments as three-dimensional (3D), multi-sensorial, immersive, real time and interactive simulations of a space that can be experienced by users via three-dimensional input and output devices. The more open approaches to virtual environments define them as a computer representation of a space. According to the latter definition, a text-based role-playing environment would be a virtual environment.
In this monograph, a virtual environment is considered to be somewhere in the continuum between those two extremes. We would define it as a three-dimensional computer representation of a space in which users can move their viewpoint freely in real time. We therefore consider that the following cases, among others, are virtual environments: 3D multi-user chats (such as Active Worlds, the Palace, etc.), first person 3D videogames (such as Quake, Unreal Tournament, etc.) and 3D virtual spaces in the web (such as those created with VRML, Adobe Atmosphere, FlatLand 3DML, etc.). There is no unified definition of virtual environments. This is partly due to the fact that they have been used (and they have proved to be useful) in a variety of fields such as videogames, interactive narrative and collaborative environments, to mention just a few. Virtual environments are already being used in the present and will play a very important role in a number of different media in the future.
The UPgrade European NETwork section also includes a paper from the Cyprus Computer Society's publication, Pliroforiki, about bio-informatics.
