Distributed Virtual Reality And Its Application in Simulation

Distributed Virtual Reality (DVR) is the integration of virtual reality and computer network technologies. DVR's most important characteristic lies in its capability of overcoming the limitation of time and space, providing a new means for human being to recognize, analyze and resolve the large scale, complex problems. DVR technology has been successfully applied in some fields such as military, aerospace, aviation, medicine, amusement etc. It also shows great prospect in the fields such as education, training, engineering design, manufacture, and e-commerce. This paper presents an overview of DVR technology, including its concept, features, development process, key techniques and application areas. And finally, the paper discusses some existing problems in DVR technology and provides some potential solutions.
