- 3. 3 ABSTRACT VIRTU AL REALITY Virtual reality or virtual realities (VR), which can be referred to as irnmersive multimedia or C omputer- simulated reality, replicates an environment that sinuLates a physical presence in places in the real world or an imal_ned world, allowing the user to interact with that world. Virtual realities artificially create sensory experience, which can include sight, touch, hearing, and smell Most up- to-date virtual realities are displayed either on a of screen or with an HD VR special stereoscopic displays, and some simuhtions include additional sensory information and focus on real sound through speakers or headphones targeted towards VR users, Some advanced haptic systems now include tactile information, genera W known as force feedback in medical, gaming and military applications, Furthermore, virtual reality covers re nice communication environments which provide virtual presence of users with the concepts of telepresence and to to or a vitual artifact (VA) ether through the use of standard input devices such as a keyboard and mouse, or through inukimodal devices such as a wired glove or omnidirectional treadmills. The immersive environment can be similar to the real world in order to creak a lifelke experience—for example, in simulatiom for piipt or combat training—or it can differ signific antiy from reality, such as in VR games, Virtual reality is an artifi2ial envirotunent 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, asually by manipulating keys or the mouse so that the content of the image moves in some direction or ziaoms in or out. More sophisticated efforts involve such approaches as wrap-around dis play screens, actual rooms augmented with wearable computers, and haptic devices that let you feel the display images.

- 6. CHAPTER 1 INTRODUCTION; The definition of virtual reality comes naturally, from the definitions thr both 'virtual' and 'reality'. The definition of clirtuar is near and reality is ‘vliat we experience as human beligs. So the term 'virtual reality' baskally means 'near-reality'. This could, of course, mean anything but it usuaily refers to a spec type of reality emulation. We no the world through our senses and perception systems. In school we all learned that we I- Kive live senses: taste, touch, mull, sight and hearing. These are however only our most obvious sense organs. 11- ie truth is that hununs imve many mom senses than this, such as a sense of balance for exampL The other sensory inputs.. plus some specid processing of sensory htbrmation by our brains ensures that we have a rich flow of information from the environment to our minds. Everything that we know about our reality co nt s b way of our senses. In other words, our entire experience of reality is sinvily a combimtion of sensory iformation and our brains sense-makiig mechanism s for that intbrmation. It stands to reason then, that if you can present your senses with madc-w hforn- ratioR yc perception of reality wouki also change in response to it. You would be presented with a version of real ii),' that in't really there, but fro rspective it would be perceived as real. Something. we would refer to as a virtual reality. Answering "what is vitail reality" in technical terms is straight -forward. Vitail reality is the term used to describe a three-climensia nal, con- puter generated envi- onment which cm be eviored and iiteracted with by a person That person becomes part of this virtual world or is immersed within this cnvironment and whist there, is able to manipulate objects or perform a series of actions. The concepts behind virtual reality are based upon theori!s about a long held hunzin desire to escape the boundaries of the 'real world' by embracing cyberspace.
- 7. 7 CHAPTER 2 litsroRY OF VIRTUAL REALITY: In 1950, flight simulators were buil by US Air Force to trail student pilots. In 1965, a research program for corrputer graphics called The Ultimate Display" was laid out. Until that time VR was just a concept and was not very popuktr.in 1988, commercial development of VR began In 1991, first comrrercial entertainment VR system was released. Virtual reality in die 21st centim The fist fifteen years of the 21st century has seen major, rapid advawe m ent in the development of virtual reality. Computer technology, especially small and powerful mobile technologies, have exploded while prices are constantly driven down_ The rise of smartpho n e s with high-dens it displays and 3D graphics capabilities has enabhd a E.- ncratK) n of lightweight aril practical virtual reality devices. The video game industry has continued to drive the development of consumer virtual reality unabated. Depth sensing cameras sensor suites, motion contrulbrs and natural human interfaces are aitady a part of daily human computing tasks. Recently companies lice Go o& have released ritual reality products such as the Googb Cardboard, a DIY headset tfut uses a smartphone to drive it, Companies lke Samsung have taken this concept further with products such as the Galaxy Gear, which is mass produced and contains "smart" features such as gesture control. Developer versions of a l consumer products have also been available for a few years, so there has been a steady stream of software projects creating content for the immanent mark_et entrance of modem virtual reality.

These iiclucle the pioneering Oculus Rift, which was purchased by social media giant Facebook in 2014 for the staggering. sum of $213N. An incredible vote of confidence in vhere the industry is set to go. When the Oculus Rift releases in 2016 it will be competing with products from Valve Corporation and FITC , Microsoft as well as Sony Con- puter Entertainment, These heavyweights are s to be followed b many other enterprises, should the market take of as expected

Fig.3.1 Augmented VR: A variation of immersive vitual reality is Augmented Reality where a see-through hyer of computer graphics is superimposed over the real world to highli ght certain features and entunce understanding One application of augmented reality is in aviation, where certain controls can be highlighted, for exam ph the controls needed to land an airplane. And many medical applications are under development (Taubes, 1994b). Recently, for the list time, a surgeon conducted surrry to remove a brail tumor using an augmented reality system; a video image superimposed with 3 - D gap hies helped the doctor to see the site of the operation more effectively (Satava, 1993)
