This paper is focused on the presentation of Virtual Reality principles together with the main implementation methods and techniques. An overview of the main development directions is included.

Virtual tour is a prominent problem in virtual reality research. In this paper, we review some virtual tour system and propose a project plan of “Virtual tour in Tsinghua University”. The core code and the prototype of the system are completed. Experimental results show that our design is feasible and effective. It can bring the feeling of reality and immersion.

The problem in trying to pin down or provide a universally acceptable definition of virtual reality is that it is still evolving. Virtual reality comes in many guises for which there is no dominant paradigm. This is in contrast to Graphical User Interfaces (GUIs) employing direct manipulation techniques through input interactive devices: keyboard and mouse. In response to fundamental questions,...

Multi-user virtual environments (MUVEs), used in training, entertainment and education, had been a reality for several years now, allowing users to perform collaborative activities using virtual settings and virtual objects. Nowadays, technological advances are opening the possibility of integrating multiuser virtual environments with so-called ubiquitous virtual reality (U-VR); extending and c...

Since 1989, when Jaron Lamier used the term for the first time, virtual reality (VR) has usually been described as a computer-simulated environment with and within which people can interact. The following are some examples of such definitions: ‘‘The terms virtual worlds, virtual cockpits, and virtual workstations were used to describe specific projects. In 1989, Jaron Lanier, CEO of VPL, coined...

Classical peripheral vestibular disorders rehabilitation is a long and costly process. While virtual reality settings have been repeatedly suggested to represent possible tools to help the rehabilitation process, no systematic study had been conducted so far. We systematically reviewed the current literature to analyze the published protocols documenting the use of virtual reality settings for ...
