Virtual reality Wikipedia. Virtual reality VR is a computer technology that uses virtual reality headsets or multi projected environments, sometimes in combination with physical environments or props, to generate realistic images, sounds and other sensations that simulate a users physical presence in a virtual or imaginary environment. A person using virtual reality equipment is able to look around the artificial world, and with high quality VR move around in it and interact with virtual features or items. The effect is commonly created by VR headsets consisting of a head mounted display with a small screen in front of the eyes, but can also be created through specially designed rooms with multiple large screens. VR systems that include transmission of vibrations and other sensations to the user through a game controller or other devices are known as haptic systems. This tactile information is generally known as force feedback in medical, video gaming and military training applications. Virtual reality also refers to remote communication environments which provide a virtual presence of users with through telepresence and telexistence or the use of a virtual artifact VA. The immersive environment can be similar to the real world in order to create a lifelike experience grounded in reality or sci fi. Augmented reality systems may also be considered a form of VR that layers virtual information over a live camera feed into a headset, or through a smartphone or tablet device. Etymology and terminologyedit. Paramount for the sensation of immersion into virtual reality are a high frame rate at least 9. Furthermore, a pixel persistence lower than 3 ms is required, because if not, users will feel sick when moving their head around. In 1. Antonin Artaud described the illusory nature of characters and objects in the theatre as la ralit virtuelle in a collection of essays, Le Thtre et son double. The English translation of this book, published in 1. The Theater and its Double,1 is the earliest published use of the term virtual reality. Noregistration upload of files up to 250MB. Not available in some countries. The term artificial reality, coined by Myron Krueger, has been in use since the 1. The term virtual reality was used in The Judas Mandala, a 1. Damien Broderick. Virtual Reality Industry research report is a meticulous investigation of current scenario of the market, which covers several market dynamics. The Global market research report is a resource, which provides current as well as upcoming technical and financial details of the industry. Dawn Of War 3D Models Download Minecraft' title='Dawn Of War 3D Models Download Minecraft' />Virtual has had the meaning being something in essence or effect, though not actually or in fact since the mid 1. The term virtual has been used in the computer sense of not physically existing but made to appear by software since 1. A cyberspace is a networked virtual reality. Virtual reality shares some elements with augmented reality or AR. AR is a type of virtual reality technology that blends what the user sees in their real surroundings with digital content generated by computer software. The additional software generated images with the virtual scene typically enhance how the real surroundings look in some way. Some AR systems use a camera to capture the users surroundings or some type of display screen which the user looks at e. Microsofts Holo. Lens, Magic Leap.

TechnologyeditThe Virtual Reality Modelling Language VRML, first introduced in 1. The Web. 3D consortium was subsequently founded in 1. D graphics. The consortium subsequently developed X3. D from the VRML framework as an archival, open source standard for web based distribution of VR content. All modern VR displays are based on technology developed for smartphones including gyroscopes and motion sensors for tracking head, hand, and body positions small HD screens for stereoscopic displays and small, lightweight and fast processors. These components led to relative affordability for independent VR developers, and lead to the 2. Oculus Rift kickstarter offering the first independently developed VR headset. Independent production of VR images and video has increased by the development of omnidirectional cameras, also known as 3. VR cameras, that have the ability to record in all directions, although at low resolutions or in highly compressed formats for online streaming. In contrast, photogrammetry is increasingly used to combine several high resolution photographs for the creation of detailed 3. Conduit Drawing Autocad'>Conduit Drawing Autocad. D objects and environments in VR applications. HistoryeditBefore the 1. The Sensorama was released in the 1. View Master, a stereoscopic visual simulator, was introduced in 1. The exact origins of virtual reality are disputed, partly because of how difficult it has been to formulate a definition for the concept of an alternative existence. Elements of virtual reality appeared as early as the 1. French avant garde playwright Antonin Artaud took the view that illusion was not distinct from reality, advocating that spectators at a play should suspend disbelief and regard the drama on stage as reality. The first references to the more modern concept of virtual reality came from science fiction. Stanley G. Weinbaums 1. Pygmalions Spectacles1. Morton Heilig wrote in the 1. Experience Theatre that could encompass all the senses in an effective manner, thus drawing the viewer into the onscreen activity. He built a prototype of his vision dubbed the Sensorama in 1. Predating digital computing, the Sensorama was a mechanical device. Heilig also developed what he referred to as the Telesphere Mask patented in 1. The patent application described the device as a telescopic television apparatus for individual use. The spectator is given a complete sensation of reality, i.

In 1. 96. 8, Ivan Sutherland, with the help of his student Bob Sproull, created what was widely considered to be the first head mounted display HMD system for use in immersive simulation applications. It was primitive both in terms of user interface and realism, and the HMD to be worn by the user was so heavy that it had to be suspended from the ceiling. The graphics comprising the virtual environment were simple wire frame model rooms. The formidable appearance of the device inspired its name, The Sword of Damocles. Battlezone, an arcade video game from 1. D vector graphics to immerse the player in a VR world. Atari. Also notable among the earlier hypermedia and virtual reality systems was the Aspen Movie Map, which was created at MIT in 1. The program was a crude virtual simulation of Aspen, Colorado in which users could wander the streets in one of the three modes summer, winter, and polygons. The first two were based on photographsthe researchers actually photographed every possible movement through the citys street grid in both seasonsand the third was a basic 3 D model of the city.

However, its hired employees, such as Tom Zimmerman, Scott Fisher, Jaron Lanier and Brenda Laurel, kept their research and development on VR related technologies. By the 1. 98. 0s the term virtual reality was popularized by Jaron Lanier, one of the modern pioneers of the field. Lanier had founded the company VPL Research in 1. VPL Research has developed several VR devices like the Data Glove, the Eye Phone, and the Audio Sphere.
