Virtual Reality : The Digital Reality

Virtual reality systems are used for simulating different real life situations on the computer which looks approximately same as the real world. In these tools, user need to wear some special cloths which has sensors attached, these sensors observe and record all the activities and responses of the user. These tools are very useful in training of many technologies like in pilot training of Boeing dreamliner, or some new technology etc.

Although this specific program will likely not become available to average consumers, the same foundations for the simulation will be available on the marketplace while being affordable at the same time. In time, applied use of virtual reality such as the Oculus Rift will become mainstream and accepted in everyday life not only due its entertainment value, but also due to its affordability for consumers everywhere. Thoughts of virtual reality often resemble fantastical scenarios reminiscent of scenes in movies with similar themes like Gamer, The Matrix, Total Recall, and Inception. After one delves into the VR technology in products such as the Oculus Rift, one will begin to believe, and he or she will brace themselves for the tidal wave that is the paradigm shift of virtual reality.

Virtual reality, also known as VR or computer simulated reality, is a new computer technology that mimic an real or imagined environment, VR simulates a user's physical presence and environment.it does this in a way that allows the person to touch and interact with it. VR aims artificially create a sensory experience for the user, which can include touch, Sight, Smell, and Hearing.

The pros of virtual reality outweigh the cons of virtual reality. Virtual reality help a lot of people that are lonely and giving them some help, maybe boosting their confidence or even providing them with information on how to do something like getting a date. According to the source: “ ‘A lot of people are lonely.’ Anderson admits. ‘ They want some sort of entertainment or companionship or a little bit of both.’” (Article 2, Page 8) This shows how, virtual reality can be used to help out the lonely people, the people that don't have confidence. Virtual reality is more of like a voice for the voiceless. Also, another way virtual reality shows how it has many pros, and those pros beat out the cons the following shows this from the text (My Virtual Girlfriend) : “I’ve been in a real relationship for almost a year and , in some ways, playing My Virtual Girlfriend reminded me of what my boyfriend and my early dalliances felt like.” Furthermore, both quotes support the claim of how people are struggling and disabled people, letting people believe, and it gives a pro over a con. It doesn't let people struggle, it gives people options, and you may ask how? Well, virtual reality allows you to believe that you are this, you are good at this that feeds into your mind and you begin to build your confidence to get that entertainment to go out

Virtual reality(VR) is a relatively new frontier in the technology industry. So new in fact, that, at its current stage, what it is and its potentials are unfamiliar to the general public. VR originally started gaining momentum as a new platform to game on, but its potential must be analyzed broadly in more than just one vocation. Because of the immersion VR provides, it has an immense capacity to benefit the educational field. Everyone is unique in the way they learn best; some people learn best by reading, some people learn audibly better, and, some people learn visually.

Imagine a world, that is anything and everything. Race a dream car. Meet a superstar. Go to Paris, New York, London, or even see the Great Pyramids. A virtual reality - an idea that is coming to life, an idea that will change the world, whether it be good or bad. Ernest Cline, the author of Ready Player One, warned us that virtual reality is going to change the world. Ready Player One is a story about a teen named Wade, in a world where video games are everything. A virtual reality world called the OASIS changed the world into a place where people are antisocial and don’t care about the world anymore. Change with VR can already be seen with the invention of the TV, the phone, the iPhone, and numerous other inventions, It’s already happening - the world is blowing up over Vive, Oculus, Hololens, and more, and VR is going to make things happen: such as solving problems. Is change happening? Are problems going to be solved? Yes, we can already see change.

In 1966, Sutherland then went forth and built an HMD that was connected to a computer system. All the graphics were created by the computer system and the HMD could also display images in stereo, giving the illusion of depth.

Last year, VR witnessed quite a lot of fame and its popularity has been constantly growing all over the world. This year, VR is expected to develop even more and to become a mainstream consumer purchase. VR is supposed to change people’s expectations and experiences across all industries and IT giants such Microsoft, Google and Samsung have already made significant investments in VR technologies.

When the mouse was developed, it revolutionized everything. Everybody is now able to point to an item on the screen. Not with arrow keys. But naturally with movement. When touch came to Smartphones, well it actually allowed the development of smartphones more or less, it revolutionized everything again. There was never a closer connection between user and content. And now, a new revolution could come: Virtual Reality. It allows the user to enter a complete isolated, imagined world, which is fully controlled by its creator. In the technology sector VR is seen as one of the key achievments which will influence our future. Despite challenges media should do the same to create a better experience than ever before.

In terms of specific applications VR can be usefully applied when building homes for disabled people. For example, those whose movements are restricted solely to a wheelchair may require larger hallway space for maneuverability and lower bench heights in the kitchen. These can easily be rectified before the house is built. Thus minimising on post-production changes which may be costly. I3 (Interactive Information Institute) is the RMIT VR 'showpiece'. It features a 150 degree wide screen which occupies the entire field of vision of the viewer. Instead of mounting a head display unit the environment is shared. I3 feature an architectural 'fly-through' of the Docklands planned area for development. This allows the user to view buildings from a multitude of different angles, and ascertain an improved idea of the finished product.

(376) Some people would argue that VR began in 1838 with the Stereoscope by Charles Wheatstone, this device was made by 'two images photographed representing the view seen by each eye '[ http://jaredjared.com/wp-content/uploads/2011/10/Bendis-Stereoscopy.pdf] placed inside a 3D headset giving the viewer depth and immersion. The first mention of VR in science fiction was in a 1930s short story called Pygmalion 's Spectacles written by Stanley G. Weinbaum, he describes a goggle based system projecting a holographic image which activates certain senses such as sound and touch[ http://www.gutenberg.org/files/22893/22893-h/22893-h.htm]. In the 1950s with Morton Heilig created The Sensorama, a machine creating sound, smells, and even wind to accompany the visuals completely mechanically. VR became more popular in theatre such as Tron (1982) and The Lawnmower Man

VR systems support 3-dimensional graphics, wide angle of view, stereovision, and viewer-centered perspective. In many VR systems the participant is not seated and is free to walk about and gesture broadly. These features make a computer system which is closer to a workshop, an operating room, or a national park than it is to a desk in an office. This perspective allows freedom in the creation of human-computer interfaces that is not afforded by the current standard interfaces [4].

Virtual reality defined as to produce and create the effect of an interactive 3D world in which the objects have a sense of spatial presence by using computer technologies. Our perceptual and cognitive system will be presented by precise clues in order for our brain to interpret and understand those clues as outside object in 3D world. In addition, virtual reality suggest a lot of benefits and advantages to education of technical such as delivery information through multiple active channels, addressing of dissimilar learning styles, experiential-based learning and so on ( Bell & Fogler, 2004, p 217).

Seeing is believing, these words are the best combination to understand the meaning of Virtual Reality (VR). VR is one of the best asset and aspect of our future. No other technology has seen such a revolution like VR has. It is practically in use in almost every field such as entertainment, gaming, defense, robotics, medical, healthcare, military, education, fashion, heritage, business, engineering and many more fields. VR sometimes called Virtual Environment has drawn much attention in the last two decade. Extensive media coverage causes the much more rapid increase in the interest of the masses. Very few people, however, really know what VR is and what are its open problems are. In this report a historical overview of virtual reality is presented, basic terminology as an introduction are listed, followed by applications of this technology in science, work, and entertainment areas. Its present developments are thoroughly discussed in this report. Finally, the future of VR is considered in two aspects: technological and social. New research directions, technological frontiers and potential applications are pointed out. The possible positive and negative influence of VR on life of average people is speculated.
