Digital Reality : Virtual 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.

In the past, virtual reality technology was thought of by many as a gimmick, and the hope for it to become a mainstream technology was discarded as products did not work as how the public envisioned. However, the proper technology is now available to make virtual reality just that: a reality. The entertainment industry is on the verge of a monumental paradigm shift that will completely transform the way these entertainment mediums are experienced.

The examples support the idea that VR is effective because it reliably gives the user the illusion of control. The writers responsible for this paper wanted to take that idea and push it to the limit. They believed that true effectiveness of virtual reality depended in part on the perception in our minds of what our actions are in direct comparison to how true the actions or movements in the VR scenario. The less cognitive dissonance between the users intended actions and the simulated actions, the more effective the simulation was in accomplishing whatever it was set to do. The researchers wanted to test dissonance in their experiment and see the outcome of how effective the virtual reality was.

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.

In your life, have you ever thought about using virtual reality? Have you ever taken to time to actually look at and think about both sides of virtual reality? Well virtual reality, is good and many people doubt that because of all the cons. But there a lot of pros that defeat these cons. It won't only help you, but it can make you happier and proud. People like to believe in a lot of things, but not everyone sees both sides of everything, especially when it comes to virtual reality. Virtual reality, it develops people it guides people. It’s like being you and creating yourself in the form that you can feel best in. It can be used to do a lot of things but many people are blind to that and just see everything one sided. Virtual reality should be allowed because it’s helpful to struggling or disabled people, therefore virtual reality isn't a cancer to the world, it’s a solution.

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.

Virtual reality is an interesting topic. Today, technology develops so rapidly, and it becomes a vital role in society.

Technology always interests us. When something new comes out, like drones or the iPhone - everyone wants one. VR will be no different. Walking through school before the bell and seeing people (sadly) at restaurants and out with their family, all of them on their new iPhone 6s’. We can see this has already happened with other products, but although VR isn’t here yet and won’t be common for years to come, the craze has already

To discuss Lanier’s keen views and anticipations regarding Virtual Reality back in the mid 1980s, it would be useful to first cover exactly how far Virtual Reality has progressed up until today. This essay will begin by discussing the history of Virtual Reality and the usage trends. That discussion will then be used to preface a discussion about Lanier’s views that were expressed in A Vintage Virtual Reality Interview. The essay will then finish off by looking at particularly interesting views held by some of today’s futurists and these views will be related back to Lanier’s original exuberant view of Virtual

of the wide spread of computers in all the layers of society it is only the

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.

(96) Virtual reality (VR) is define as a cybernetic simulation of 3D surroundings which can be interactive through auditory, sensory and visually stimulating equipment, i.e. gloves, headgear or headphones. VR is an incredibly recent development in technology and such has much room to progress with, I believe that VR is the future of animation as the key aim is to transport the viewer into the world we have created, VR being the next logical step as it creates this suspension of belief as well as activating all of the senses we use to perceive the real world.

VR is more than an upgraded version of Cinerama or a theme park ride, as it achieves not only a greater sense of presence, but through the use of computer technology, the capacity to direct one’s gaze and movements so that one can explore and move around inside the illusory flow of images [3]. The main imperfection in simulation at present comes from the difficulties inherent in presenting a sufficiently convincing computer generated image. Presenting a convincing visual input to a human being requires a computer which can handle a vast amount of information. This is both difficult and expensive with existing technology.

Furthermore, according to Shaojing Fan, Yongping Zhang, Jianbo Fan, Zhongkun He and Yu Chen (2010), virtual reality is an emerging technology with a variety of potential benefits for many aspects of education, medical treatment, and scientific research. One of advantages of Virtual Reality is people can immerse themselves in an environment that would generally be unavailable due to cost, safety or perception restriction. Research by Abulrub, Attridge and Williams (2011) suggested that a new generation of engineering students is entering higher education level with their own worth computing knowledge and skills. They also have high expectations that their institutes will introduce them to suitable technologies for their successful transformation into industry. Technological requirements encounter academic institutions to adopt appropriate and suitable strategies in order to meet all of educational demand. Hence, virtual reality is one of the best solutions as its solution and advancement in immersive and interactive technologies can give visible and noticeable effects on different style and learning. Moreover, virtual reality known as technology that is attractive to students.

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.
