About this computer paper-presentations : (Virtual reality ) The term 'Virtual Reality' (VR) was initially coined by Jaron Lanier, founder of VPL Research (1989). Other related terms include 'Artificial Reality' (Myron Krueger, 1970s), 'Cyberspace' (William Gibson, 1984), and, more recently, 'Virtual Worlds' and 'Virtual Environments' (1990s).
The relationship between our actions and their perceivable results is ruled by what we call the laws of nature. It is general understanding that our actions act upon real objects, which react according to the laws of nature, what then can be perceived. Virtual Reality Facilities (VRFs) simulate the action perception relationship in a physically correct manner but without involving real objects or real events. Just the same do mathematical models of nature (physical theories). So it stands to reason that VRFs can be considered as analog models of nature.
If a physical theory is false its predictions cannot be verified. If a VRF were false we would have strange and unusual perceptions as if different laws of nature would be valid. It is suggesting to say that we would fail to survive in nature when using a false mathematical as well as a false analog model. So, an analog model of nature can be useful even if it is not 'true'.
Virtual Reality is an enabling technology that has wide applications in training, product design, etc. Virtual reality (VR) technology is being used to resolve problems in real-world situations. The National Aeronautics and Space Administration (NASA) is using VR to train astronauts to repair the Hubble Space Telescope. In this talk, we present a brief introduction into Virtual Reality as a human centered interface technology.
