Virtual Reality (VR) is also called computer simulated reality or immersive multimedia. It replicates environments which simulate presence physically in place in imagined world or real world. It allows user interaction in that specific world. Virtual Reality creates artificially experiences of senses like smell, sight, touch and hearing. Presently, most Virtual Reality has been displayed on either screen of computer or with stereoscopic special displays. Few simulations include additional focus and sensory information on real sounds by means of headphones or speakers being targeted to users of VR. Few haptic advanced systems include tactile information called as “force feedback” in military, medical and gaming applications. VR covers environments of remote communication that provides virtual user presence with concepts of telexistence and telepresence or (VA) virtual artefact. It uses either input standard devices like mouse and keyboard or by means of multimodal devices like omni-directional treadmills or wired glove. Simulated environments are same as real worlds for creating lifelike experiences. Example is, in combat training or in pilot simulations or in VR games.
Education: In education realms strides are done and made. Though there are lots of requirements still needed for conducting. Possibilities of education and VR are endless. VR brings lots of benefits to people of all age groups. Few create content used for purposes of education. Most advancement is brought about in industry of entertainment. But many realize and understand future and necessity of VR and education. Training: VR usages in perspective of training allows professional for conducting training in virtual environments in which they improve on skills with no consequences of failing operation. VR is most integral part in military’s combat training. It allows recruiting training under controlled environments in which they give responses to lots of types of situations of combat. Fully immersive Virtual Reality uses data suits, (HMD) Head-mounted Display, VR weapon and data glove for training combats. Setup allows reset time of training being cutting down, thereby allowing more repetitions in short time periods. Training environment fully immersive allow soldiers training by means of wide varieties of scenarios, terrains and situations.
Video games: Use of input, sound and graphic technology in video games is incorporated to VR. Much Virtual Reality (HMD) head mounted displays are released for purposes of gaming during 1990s early-mid. This included Virtual Boy being developed by Nintendo. Then there was iGlasses being developed by Virtual I-O. Then there was Cybermaxx being developed by Victormaxx. Then there was VFX1 Headgear being developed by Forte Technologies. Different latest examples of narrow gaming VR’s includes PlayStation Move, Wii Remote, PlayStation Eye and Kinect. All of these send and track motion inputs of players to gaming consoles nearly correctly. Fine arts: David Em was 1st fine artist who created navigable worlds virtual in year 1970s. His early works were done on main-frames at California Institute of Technology, Information International, Inc. and Jet Propulsion Laboratory. Jeffrey Shaw explored VR potentials in fine arts with works early like Golden Calf (1994), Legible City (1989) and Virtual Museum (1991). Canadian artist namely Char Davies had created VR immersive art pieces like Ephemere (1998) and Osmose (1995). Work of Maurice Benayoun introduced political, metaphorical or philosophical contents combining intelligent, VR, network and generation agents in workings like “The Tunnel under the Atlantic (1995)”, “Is God Flat? (1994)”, “World Skin, a Photo Safari in the Land of War (1997)”, and “Is the Devil Curved? (1995)”. Different other artists pioneering in turn working in realm of VR include Brenda Laurel, Luc Courchesne, Jacki Morie, Rebecca Allen, Margaret Dolinsky, Rita Addison, Knowbotic Research and Perry Hoberman. All artists mentioned have been documented in Database of Virtual Art.
