Virtual Reality (VR), sometimes called Virtual Environments (VE) has drawn much attention in the last few years. Extensive media coverage causes this interest to grow rapidly. Very few people, however, really know what VR is, what its basic principles and its open problems are. In this paper a historical overview of virtual reality is presented, basic terminology and classes of VR systems are listed, followed by applications of this technology in science, work, and entertainment areas. An insightful study of typical VR systems is done. All components of V R application and interrelations between them are thoroughly examined: input devices, output devices and software. Additionally human factors and their implication on the design issues of VE are discussed. Finally, the future of VR is considered in two aspects: technological and social. New research directions, technological frontiers and potential applications are pointed out. The possible positive and negative influence of VR on life of average people is speculated. 1.2. What is VR? What is VR not? At the beginning of 1990s the development in the field of virtual reality became much more stormy and the term Virtual Reality itself became extremely popular. We can hear about Virtual Reality nearly in all sort of media, people use this term very often and they misuse it in many cases too. The reason is that this new, promising and fascinating technology captures greater interest of people than e.g., computer graphics. The consequence of this state is that nowadays the border between 3D computer graphics and Virtual Reality becomes fuzzy. Therefore in the following sections some definitions of Virtual Reality and its basic principles are presented. 1.2.1. Some basic definitions and terminology Virtual Reality (VR) and Virtual Environments (VE) are used in computer community interchangeably. These terms are the most popular and most often used, but there are many other. Just to mention a few most important ones: Synthetic Experience, Virtual Worlds,

“…(d) Re-Imaging/Projection: The majority of volumetric displays prototyped to date employ only the above three subsystems. However, a re-imaging and/or projection subsystem may also be present and serves to modify the direction of light emitted by the voxel generation subsystem and/or project light such that an image scene appears to exist in free space (see, for example, Kameyama et al 1993, Kameyama and Ohtomi 1993, Blundell and Schwarz 2006. Usually in the absence of this subsystem image content resides within physically bounded image space.…”

Volumetric displays permit electronically processed images to be depicted within a transparent physical volume and enable a range of cues to depth to be inherently associated with image content. Further, images can be viewed directly by multiple simultaneous observers who are able to change vantage positions in a natural way. On the basis of research to date, we assume that the technologies needed to implement useful volumetric displays able to support translucent image formation are available and so primarily focus on other issues that have impeded the broad commercialization and application of this display paradigm. This is of particular relevance given the recent resurgence of interest in developing commercially viable, general purpose, volumetric systems. We particularly consider image and display characteristics, usability issues and identify several advantageous attributes that need to be exploited in order to effectively capitalize on this display modality.

“…This way the designer can carry out the modeling process, while being in a very direct relationship with the model. VE systems, which support this level of interaction with the participant, are still at an experimental stage of development and most of this research is done with non-immersive VR systems (Kameyama & Ohtomi, 1993, Fernando et al 1994. Finally, Slater and Steed (1994) and Slater & Usoh (1994) have also experimented with systems which support modeling of generic objects by an immersed participant.…”
