The Strange New World of Virtual Reality
Virtual Reality is a creation of a highly interactive computer based multimedia environment in which the user becomes a participant with the computer in a "virtually real" world. We are living in an era characterized by 3D virtual systems created by computer graphics. In the concept called Virtual Reality (VR), the virtual reality engineer is combining computer, video, image-processing, and sensor technologies so that a human can enter into and react with spaces generated by computer graphics.
In 1969-70, a MIT scientist went to the University of Utah, where he began to work with vector generated graphics. He built a see-through helmet that used television screens and half-silvered mirrors, so that the environment was visible through the TV displays.
It was not yet designed to provide a surrounding environment. It was not until the mid '80's that virtual reality systems were becoming more defined. The AMES contract started in 1985, came up with the first glove in February 1986. The glove is made of thin Lycra and is fitted with 15 sensors that monitor finger flexion, extension, hand position and orientation. Connected to a computer through fiber optic cables. sensor inputs enable the computer to generate an on screen image of the hand that follows the operator's hand movements. The glove also has miniature vibrators in the finger tips to provide feedback to the operator from grasped virtual objects. Therefore, driven by the proper software, the system allows the operator to interact by grabbing and moving a virtual object within a simulated room, while experiencing the "feel" of the object.
The virtual reality line includes the Datasuit and the Eyephone. The Dtasuit is an instrumented full-body garment that enables full-body interaction with a computer constructed virtual world. In one use, this product is worn by film actors to give realistic movement to animated characters in computer generated special effects. The Eyephone is a head mounted stereo display that shows a computer made virtual world in full color and 3D.
The Eyephone technology is based on an experimental Virtual Interface Environment Workstation (VIEW) design. VIEW is a head-mounted stereoscopic display system with two 3.9 inch television screens, one for each eye. The display can be a computer generated scene or a real environment sent by remote video cameras. Sound effects delivered to the headset increase the realism.
It was intended to use the glove and software for such ideas as a surgical simulation, or "3D virtual surgery" for medical students.

Virtual Reality got famous from the gaming industry and from sci-fi movies. In science fiction films there were numerous scenes about person wearing goggles and then looking into a different world or a portal. Things which are presented in movies do fascinate the viewers and so the real Virtual Reality concept came to life. This thing was also seen from the gaming industry as one of the biggest Graphics Processing Chip Company NVidia built its first stereoscopic goggles called NVidia 3D vision. The sole purpose of those glasses was to wear them while playing a game and it will make you feel like you are the character and you are inside the game. Some of the games which made this technology popular are Battlefield, Batman, HAWX and
...nd helpless civilians and even remove an offending regime. On the other hand, Russia and China continue to validate the traditional state system embodied in the Peace of Westphalia, the series of seventeenth-century treaties that ended the Thirty Years War in Europe. The main principle of the treaty system is a general prevention against outside interference in the purely internal affairs of other countries. These conflicting views of the great powers could lead to a possibility of militarized action if any other country personally intervenes with Syria’s Civil War. This could create another Cold War or even a full scale war.
The simulated reality hypothesis is a simple idea that says that we, and everything in the known universe, is currently living inside a computer simulation. This idea has been talked about by philosophers for centuries and even has some ties to religion. Sci-fi writers have been writing about simulated reality for years and we have seen it visualised on tv shows yet the idea that we may be living inside of a computer simulation is almost unknown to most people.
Do you know how factory farms affect your health, the world around you, and your children 's future? Factory farms are one of the major leading causes of pollution ,which causes a great amount of problems. The animals produced by the masses on these factory farms are extremely exploited and treated inhumanely. The methane from tons of animal manure is causing detrimental global warming. Global warming is affecting much more than the temperature, its damaging crops, species of animals are going extinct, and humans are having health problems. Raising livestock requires a great amount of land ,including animal habitats and rainforests that used to nourish the planet. Factory farms have the U.S. food production
According to the Organic Consumers Association, in 1970 there were approximately 900,000 family farms in the United States; by 1997 there were only 139,000 family farms. This number is continually decreasing by the year. Why is this a problem? Factory farms promote abusive practices in order to maximize production at minimal cost at the expense of the environment, the community, and even our personal health. They house thousands of animals and inject them with hormones in order to maximize their growth and food output. The techniques being used are inhumane and are used thousands of times a day. According to the Organic Consumers Association, two out of every three animal products in stores come from factory farms. Factory farms dominate food production throughout the country. Animals most commonly consumed that require large-scale farming practices are cows, chickens and pigs. The methods of farming are not only bad for the animals themselves, but it’s affecting the meat we put into our bodies, and is therefore affecting one’s health. Factory farms ultimately have a negative effect on the health of both the animal and the consumer of the animal product.
The purpose of this paper is to explain how virtual reality is used in everyday life. It is used in many ways in today's society. Several people immediately think of video games or entertainment when they hear virtual reality. Virtual reality is not only used for entertainment purposes but it is also used for medical and educational purposes. It can help people overcome their fears, deal with and treat social anxiety, and it can also be a helpful teaching tool to connect students and teachers in long-distance learning.
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.
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.
Computer Generated Images, or CGI, is a form of Computer Graphics design, and animations, that make a image look 3D. These images are shown all throughout the media world, industry, and business, such as print media, tv, movies, pictures, commercials, etc. CGI’s have improved rapidly on software that helps our world improve on computer generated imaging. CGI software’s is used to make graphical design for purposes like movies in the theater. CGI companies and software’s, has made the technology age, and its computer has increase in speeds, and has allowed computer graphics programmers, and other companies, to make better quality films, games, and electronic digital photos on their CPU’s, or laptops. Because of the new advancement in software technology in CGI, and graphics designing, it has brought new internet religious cultures, its own new experiences, such as celebrities, and newer technological vocabulary. Technology advancement has increased so much that CGI’s has lead to the new beginning or era of virtual cinema photography.
Using a MUD does not require the paraphernalia commonly associated with virtual reality. There is no special hardware to sense the position and orientation of the user’s real-world body, and no special clothes allowing users to see the virtual world through goggles and though through “data gloves”…Instead of using sophisticated tools to see, touch and hear the virtual environment, users of MUD systems are presented with textual descriptions of virtual locations. Technically, a MUD software program consists of a database of “rooms”, “exits” and other objects. The program accepts connections from users on a computer network, and provides each user with access to that database…Within each system users can interact with each other and with the virtual environment which the MUD presents to them (Reid, 1994).
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 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 is a new form of interactive media that is here to stay. A time may come when people might get tired of it but the chances of that happening are really low as the content that can be offered in VR systems is almost limitless.
