MULTIMEDIA AND VIRTUAL REALITY
Virtual reality is an artificial environment that is created with software and presented to the user in such a way that the user suspends belief and accepts it as a real environment. On a computer, virtual reality is primarily experienced through two of the five senses: sight and sound.
The simplest form of virtual reality is a 3-D image that can be explored interactively at a personal computer, usually by manipulating keys or the mouse so that the content of the image moves in some direction or zooms in or out. More sophisticated efforts involve such approaches as wrap-around display screens, actual rooms augmented with wearable computers, and hap tics devices that let you feel the display images.

The crucial goal is coined in the term immersion. A virtual reality demonstration or production is successful if (even to a small or limited degree) during that presentation the viewer/ listener/ game-player has a sense of being apart from the world they are truly occupying and experience an immersion in an alternative environment. But this definition too requires some qualification. To this must be added that the sense of immersion must be mediated solely by the senses and not by mental association and ideas. I expect you - like me - have read a gripping novel on an airplane only to have glanced up and experienced the sensation of being dragged away from the fictional world of the book. If you recognize this, then you know those seconds of disorientation whilst adapting to the true reality. But this is an "immersion" which is mediated by the imagination. This way, the link with multimedia can be most clearly seen, since the all embracing task of creating an empirical alternative sense of reality must, by definition, involve media which impinge on more than one sense. Moreover, the true essence of virtual reality is in both creating convincing sensory inputs and a creating a realistic impression that one's own actions and behaviors impact and influence a virtual world in a realistic and convincing way. Simply put, we must be able to interact with this alternative …show more content…
Many worry about the uses it will be put; fearing the human race will evolve into insouciant libertines gorged on a diet of ersatz sex! For those who dread what the future will bring to a human race given reign to experience its personal "fantasy realities", it's worth noting that the stereoscopic viewer - the nearest anyone could get to a virtual reality system at the time - fell into ill-repute in Victorian times due to the proliferation of pornographic material. It seems the engineering progress which has accompanied the presentation of virtual reality has not been matched by a commensurate progress in the fantasies which people hope to have sated by that technology! It is with some sadness that Gates (1995) predicts that concupiscence will almost certainly be the driving factor in low-cost virtual reality systems. So is the future for VR predominantly as a vehicle for entertainment? Is it going to be good for anyone but salacious epicures? Certainly the key concept of immersion does perhaps suggest its predominant applications exist more in the world of our fantasies than in the world of our duties. However there are a raft of applications where VR and multimedia concepts and technologies are beginning to contribute to our abilities to execute our jobs, perform new jobs or do old jobs differently. Not strictly pure VR or multimedia, three important categories are
Virtual reality gives a computer-generated simulation of a three-dimensional picture or environment that encompasses a client and can be associated with in an apparently real or physical way by an individual utilizing uncommon electronic equipment, for example, a helmet with a screen inside or gloves fitted with sensors. It has the capacity react, typically through immersive head-mounted displays (HMDs) and head tracking. Gloves giving hand tracking and haptic/touch-delicate feedback may be utilized too. Room-based frameworks give a three dimensional experience to various users; nonetheless, they are more constrained in communication abilities. A standout amongst the most popular virtual reality gadgets is the Oculus Rift.
By the virtuality of a thing I mean the seeming of it, as distinct from its more concrete "reality," which may not be important. ... I use the term "virtual" in its traditional sense, an opposite of "real". The reality of a movie includes how the scenery was painted and where the actors were repositioned between shots, but who cares? The virtuality of a movie is what seems to be in it.
Discover a universe of possibilities and explore the world like never before. Virtual Reality (VR) brings you to distant lands, places you in the middle of an Elvis Presley performance and brings you face to face with an inhabitant from a different universe.
...cal and theoretical issues related to the technologies of immersive virtual reality, netart, and avatars; specifically with respect to issues of identity, embodiment, and human sentience. He has presented and exhibited his work in numerous international venues, including Ars Electronica, Invencao, Consciousness Reframed, Webs of Discourse, CADE, as well as museums, galleries, and alternative spaces. His essay, “A Manifesto for Avatars” was published in Intertexts in 1998. At present he is a visiting researcher at the Virtual Reality Centre at the University of Teesside, and at the CAVE Lab, New Media Center, The University of Michigan. He is a Visiting Assistant Professor of Computer Art/New Media at Bowling Green State University, and an Assistant Professor of Art at Kent State University.
Now that you have understood augmented reality, it should be easier for you to understand virtual reality. To explain in easy terms, in virtual reality you as a user are taken into the virtual world. Contrast it with augmented reality where the virtual objects make their way into your world. Once you are in the virtual world, you can move in this world, interact with those objects and to some extent end up believing that this is your real world. You can segment virtual reality into many types based on DOF (degrees of freedom). To explain DOF in easy terms, this is a measure of how freely you can interact with the virtual world you are in and move around in
A common misconception is that virtual reality is just for entertainment. As we contemplate about some of the technology involved in virtual reality, entertainment is generally the first thing a lot of people think of when virtual reality springs to mind, but here we will talk about some of the other areas that virtual reality has made some substantial differences.
But if we are looking for a more modern take on virtual reality we would start in the early 1800’s with a paint style called “Panoramic paintings”. So what are these and how do they relate to virtual reality. Well these paintings were made to fill a person’s field of vision, making them feel like they are at the historical event, scene, or battle they are looking at. (“History Of Virtual Reality”, 2017).
The main goal of virtual reality is to take its user into a virtual world. It provides a virtual space where almost everything is possible. Virtual reality works by tricking the parts of the brain that perceive motion.
The definition of virtual reality comes, naturally, from the definitions for both ‘virtual’ and ‘reality’. The definition of ‘virtual’ is near and reality is what we experience as human beings. So, the term ‘virtual reality’ basically means ‘near-reality’. This could, of course, mean anything but it usually refers to a specific type of reality emulation. Also, virtual reality is the term used to describe a three-dimensional, computer generated environment which a person can explore and interact with. That person becomes part of this virtual world or is immersed within this environment and whilst there, a series of actions can be manipulated objects or performed.
Virtual reality is a very new interest of a lot of companies working with technology and gaming industry at it is found to be a gold mine for business that due to the technological explosion over the last century has found a large group of investors into that idea and used to show the public a new experience and an invention that has found a place in history, so love VR some hate it of course but then there are many things that are able to be done with this concept, the potential of it is priceless.
The term Virtual Reality (VR) is used by many different people with many meanings. There are some people to whom VR is a specific collection of technologies, that is a Head Mounted Display, Glove Input Device and Audio. Some other people stretch the term to include conventional books, movies or pure fantasy and imagination. However, for purposes of this research, we restrict VR to computer mediated systems. We would define Virtual Reality as a way for humans to visualize, manipulate and interact with computers and extremely complex data.
Virtual reality can be defined as a, "technology that enables users to enter computer generated worlds and interface with them three dimensionally through sight, sound, and touch" (Newquist 93). Virtual reality combines computer simulation and visualization into a single, coherent whole (Peterson 8). Researchers say it embodies an attempt to eliminate the traditional distinction between the user and the machine. Virtual reality is intended to provide a means of naturally and intelligently interacting with information (8). Virtual reality is contending to be the interface of the future, allowing ordinary users to use their senses to interact with complex data.
Definition of virtual reality is "A technology that assures participants that he was actually in another place by replacing the main sensory input with data received by the computer" [6] [10]. One of the key elements of the virtual reality of cyberspace; it is a space fantasy or simulation environment. Which is always linked here is a virtual world and immersion virtual reality, perception is born into the world of alternatives such as ethereal or other point of view of our world
Virtual reality gives huge benefits in education and helps to improve student engagement. It’s one of the best ways to engage and helps the students to understand the subject through virtual reality system. Especially in the virtual reality game will bring significant impact to teenagers. The major three types of impact are social difficulty (socially impaired), physical and psychological difficulty. Even virtual reality is a great tool to learn, but it is not a universal learning method for all of the educational areas. Too much of virtual reality for students will cause social difficulties because an inescapable aspect of social life is the formation and maintenance of interpersonal relationships (Biocca and Levy 1995). Constantly using virtual reality will cause isolation from the societies because the person already made his or her own social area which only exists in the virtual world. VR will provide a communication environment in which the dangers of deception and the benefits of creativity are amplified beyond the levels that humans currently experience in their interpersonal interactions (Biocca and Levy 1995). It could lead to low self-esteem, feelings of worthlessness and insignificance, even self-destructive acts (Cartwright, 1994). VR games could mindlessly, energy sapping diversion, bring electronic isolation, a playground for immortality (Kershner 1995). Virtual Reality game brings physical and psychological difficulties when they over run and it could be called as cyber sickness. VR interventions were able to increase physical activity capacity and performance in children with CP (Cerebral palsy) or early brain injury. Cyber sickness is one of the physiological impacts durin...
Virtual Reality allows designers and developers to create an experience that is not real, but gives the effects and the experience as being real, hence, a virtual reality! There are many ways in which this can be used such as for games, simulations, training, experiencing a distant location from the comfort of your home and so much more.
