According to the website of Virtual Reality Society, the technical specification for virtual reality is a three-dimensional, computer-generated environment which can be explored and interacted with by a person. Virtual reality makes use of our senses to allow us to explore environments, manipulate objects
This depicts variety of games such as science fiction, superheroes, sports, horror and even historical. Most of these virtual games have real time actions. These are not only restricted to games, but computer based conferencing and text based chat rooms is also done. Sometimes “ Smilies” are also present to represent our feelings. CONCEPT OF VIRTUAL WORLD The most important feature of virtual world is “PERSISTENCY” that it
While immersed, the user cannot see the real world around him. In contrast, AR allows the user to see the real world, with virtual objects superimposed upon or composited with the real world. Therefore, AR supplements reality, rather than completely replacing
Ijsselsteijn & Riva came up with presence, which is the experience of ‘being there’ in a mediated environment. It has become closely associated with virtual reality (VR) and other advanced media as well as playing role in engendering a sense of presence. There are also different types of presence including the physical presence, social presence, and co-presence (Ijsselsteijn & Riva, 2003). On the other hand, Timmins & Lombard have explained the confusions that occur regarding what is the virtual (mediated by technology) and real (non-mediated). They have stated three categories of the illusion of mediation which are the positive, negative and unusual which are labelled as the inverse presence (Timmins & Lombard, 2005).
So a simple question arises “what is Virtual-Reality”? Virtual-Reality is referred to the Computer (Programming) stimulated life which creates a virtual or imaginary world. It replicates only the physical presence of a real life; but all the control system of that real life is stimulated by an unknown program through which one can interact with that world. The stimulated environment can create such a real feelings that it is difficult for anyone to differentiate between the artificial experiences and real ones. One of the famous British Philosopher Nick Bostorm proposed a theory that “Everything that one have ever done or will do could simply be a product of a highly-advanced computer code.
What is Virtual Reality? • Virtual reality is a completely artificial digital environment that uses computer hardware and software to create the appearance of a real environment to the user. For a user to “enter” a Virtual Reality environment, they must first put on special gloves, earphones, and goggles, all of which receive their input from the computer system as can be seen in the Figure below. • By doing this, at least three of the five senses are controlled by the computer. In addition, the computer monitors the user’s actions.
You will be presented with a version of reality that isn’t really there, but from your viewpoint it will be perceived as real. Sometimes we would refer to as a virtual reality. Therefore, virtual reality involves presenting our senses with a computer-generated virtual environment that can be explored any way we want. Technically if we describe
“I think it’s fair to say that personal computers have become the most empowering tool ... They’re tools of communication, they’re tools of creativity, and they can be shaped by their user.” (Gates) This was famously said by Bill Gates and that has never been truer, especially in today’s fast-paced world. With all of this going on, remote access allows us to access all this through our personal computer at the place of our choice. As a society, we constantly relay on the personal computer and it’s abilities as a medium. Often times we remotely access information using a computer and do this without our knowledge. What is remote access?
People who faced virtual reality have become a part of the virtualisation, which gives the ability to users of a feeling of reality and makes them able to perform a series of actions, such as the manipulation of several objects through a computer simulation (Dix, Finlay, Abowd & Beale, 2004). Moreover, VR is trying to visualise the real world and replicate it, in order to give humans the actual appearance of the objects. A simple example of Virtual Reality that everybody uses is the iconic bin in the “Desktop” of any PC, which can sent different files in it by deleting them and manipulates them as the user wants (Heim, 1993). The chapters that will follow are analysing the history of VR, the benefits that they provide and the disadvantages that they might
For example, when they study Science they can learn more about the human body with the three dimensional images of the human body. Virtual reality application also can bring people to explore more about the game world. This is because it is in three dimensional images and people can feel like they are in the real situation of the
