Oculus' virtual reality ambitions extend well past  standalone headsets . In a talk at Oculus Connect 5, the company's Michael Abrash updated his predictions for the future of VR headset technology. Most notably, he sees an end to the  bulky headsets  that define the experience today. Pancake lenses (already in use with interchangeable lens cameras) could slim down headsets or lead to ultra-wide fields of view, but the real star may be  waveguide displays , where light bounces down extremely thin glass plates. You could see VR headsets that are scarcely thicker than glasses, with images that are as wide as you need. Abrash showed a concept drawing (this isn't a hint at a future product, he stressed) for a headset that would make your Rift or Go look positively ancient, although he wouldn't predict just when you might see such a device. You would also see augmented reality glasses that are "socially acceptable,"

 As people start staying in a virtual world more than real which could affect his social and mental health, people start experiencing headache, blurred vision, visual fatigue and difficulty in focusing being in a virtual environment for a long time

Travel companies are using virtual reality to allow customers to visit places and determine if they wish to visit in real life. Although virtual reality can be used for gaming, it is also becoming popular for other purposes such as allowing a person to feel as if they are in a virtual reality documentary. Virtual reality is being used in health care. It allows medical students to practice dangerous procedures and gain experience without actually operating on a human. It can also help surgeons determine the best point of entry for surgeries. Scientists with NASA can use virtual reality to enable robot arms in space to perform gestures that are being done on earth with an operator. Militaries are now using virtual reality to train soldiers in ways that will help better prepare them when they are actually deployed in combat. Oculus VR is a company that launched a Kickstarter project to release virtual reality goggles in the 2010s. Their goggles brought a lot of interest to virtua

At the end of my research I had gained a lot of knowledge about Virtual Reality such as about the history and application. I feel that this technology has a lot of scope in future in all the aspects such as in professional occupations, education and gaming. This technology would build one more virtual world where everyone would live in their own graphic character in this world. VR has a number of advantages but I also found out that it has many disadvantages also.

STIMULATOR There are many kinds of stimulators such as airplane stimulator, ship stimulator and car stimulator which are the same as the real and much safer to practice on. GAMING VR has changed the face of gaming, now gamers can play being an actual graphic character in the game. EDUCATION VR offers very different kinds of experience than those students normally encounter in school. Students can actually experience what they learn which would make their learning effective. MEDICAL Medical applications for virtual reality (VR) are just beginning to emerge. These include VR surgical simulators, telepresence surgery, complex medical database visualization, and rehabilitation. The VR surgical simulator is a stylized recreation of the human abdomen with several essential organs, a person can learn anatomy from a new perspective by ‘flying’ inside and around the organs, or can practice surgical procedures with a scalpel and clamps.

As a start-up growing at hyper speed, Oculus VR recognized it was at risk of losing its inherent cultural traits: a closely knit team of equal intellectuals, where constant chatter and close proximity kept ideas flowing and colliding constantly, sometimes literally sticking to walls, as new prototypes spilled continuously out of 3D printers. And all of this happened while a telepresence robot digitally connected one Oculus engineer working in Dallas to team members in California. Their existing space was not working for them. Furnished with rigid, linear benching, conversations were constrained, conducted standing up, or leaning over others. Product Lead Joe Chen was frustrated that it didn’t really foster the right kind of interaction; “accidental collaborations” that happen spontaneously were too infrequent. There weren’t enough spots for quiet conversations, either. He wanted to enhance the connectivity and impromptu discussions that are inherent to the company’s success. They also

VIRTUAL REALITY Virtual reality (VR) is also known as Virtual Environment (VE) which basically means Real time interactive graphics with 3D models that is combined with a display technology which gives the user the immersion in the model world and direct manipulation (Fuch 1992), occupations such as architecture, engineering and interior designing would be difficult to imagine without graphical workstations. This essay will mainly talk about the history of virtual reality, future development possible on this topic, advantages and disadvantages of VR. The main idea of virtual reality had started in 1929 and since then there have been a number of developments that took place in this technology. A simple mechanical flight stimulator which was developed by Edward Link to train the pilots at stationary (Sherman R.W. Craig A.B. 2003). Which was the first step towards the technology virtual reality, then Morton Heilig in 1956 had created a multi-sensory simulator, it was a pre-

VR is an excellent technology that has a number of advantages, however this technology also has some disadvantages also such as people start staying in a virtual world more than real which could affect his social and mental health, people start experiencing headache, blurred vision, visual fatigue and difficulty in focusing being in a virtual environment for a long time (Griffin J.; Lewis C.H. (1997)). In conclusion, VR is a positive technology that can change the way of living of a person, making it easier and safer. People can now do the thing they dream, visit places without actually travelling which make is more cost efficient.

After that there were a number of developments such as the Ultimate Display (1965) by Ivan Sutherland and Videoplace (1975) by Myron Krueger . Then came Augmented Reality(AR) which was one of the biggest development in VR, AR is a technology that presents a virtual world which enriches rather that replacing the real world (Mazuryk T. Gervautz M. 1996). VR can be used at an important tool in number of places, both in professional field as well as entertainment such as VR are used in stimulators which are for entertainment and can also be used for training pilots, car drivers, it can also be used in education so that the students can virtually experience whatever they learn which makes it more effective for them and it can also be used in gaming for entertainment which has completely changed the face of gaming  (Satava R.M. 1996) .

The main idea of virtual reality had started in 1929 and since then there have been a number of developments that took place in this technology. A simple mechanical flight stimulator which was developed by Edward Link to train the pilots at stationary (Sherman R.W. Craig A.B. 2003). Which was the first step towards the technology virtual reality, then Morton Heilig in 1956 had created a multi-sensory simulator, it was a pre-recorded film in stereo and colour and also added with scent, wind, binaural sound, and vibration experiences which was called Sensorama (Sherman R.W. Craig A.B. 2003). Has to be continued...... 

Nowadays computer graphics is used in many domains of our life. At the end of the 20th century it is difficult to imagine an architect, engineer, or interior designer working without a graphics workstation. In the last years the stormy development of microprocessor technology brings faster and faster computers to the market. These machines are equipped with better and faster graphics boards and their prices fall down rapidly. It becomes possible even for an average user, to move into the world of computer graphics. This fascination with a new reality often starts with computer games and lasts forever. It allows to see the surrounding world in other dimension and to experience things that are not accessible in real life or even not yet created.

• Sensorama – in years 1960-1962 Morton Heilig created a multi-sensory simulator. A prerecorded film in color and stereo, was augmented by binaural sound, scent, wind and vibration experiences. This was the first approach to create a virtual reality system and it had all the features of such an environment, but it was not interactive. • The Ultimate Display – in 1965 Ivan Sutherland proposed the ultimate solution of virtual reality: an artificial world construction concept that included interactive graphics, force-feedback, sound, smell and taste. • The Sword of Damocles– the first virtual reality system realized in hardware, not in concept. Ivan Sutherland constructs a device considered as the first Head Mounted Display (HMD), with appropriate head tracking. It supported a stereo view that was updated correctly according to the user’s head position and orientation. • GROPE – the first prototype of a force-feedback system realized at the University of North Carolina (UNC)

Virtual reality (VR) is also known as Virtual Environment (VE) which basically means Real time interactive graphics with 3 dimensional models that is combined with a display technology which gives the user the immersion in the model world and direct manipulation (Fuch 1992), occupations such as architecture, engineering and interior designing would be difficult to imagine without graphical workstations. This essay will mainly talk about the history of virtual reality, future development possible on this topic, advantages and disadvantages of VR.

At the beginning of 1990's the development in the field of virtual reality became much stormier and the term Virtual Reality itself became extremely popular. We can hear about Virtual Reality nearly in all sort of media, people use this term very often and they misuse it in many cases too. The reason is that this new, promising and fascinating technology captures greater interest of people than e.g., computer graphics. The consequence of this state is that nowadays the border between 3 dimensional computer graphics and Virtual Reality becomes fuzzy ( Mazuryk,  Gervautz 1996).
