What Is Virtual Reality (VR)?

Virtual Reality is a computer-generated environment, which allows a person to experience it in reality

Virtual Reality commonly known as VR is a computer simulation (assumption of false appearance) of a true or unreal system, that permits a user to perform operations on the simulated system and shows the results in real time.

In a lay-man language, Virtual Reality is a computer-generated environment. It allows experiencing the artificial environment which doesn’t exist.

What is Virtual Reality?

Few of us probably never visit Mars, swim with dolphins, run an Olympic a hundred meters, or sing onstage with the Rolling Stones. However, if virtual reality ever lives up to its promise, you would possibly be able to do of these things—and several more—without even going away from your home. Not like real reality, virtual reality means that simulating bits of our worlds (or fully imagined worlds) using superior computers and sensory instrumentation, like headsets and gloves. Aside from games and recreation, it’s long been used for coaching airline pilots and surgeons, and for serving to scientists to work out advanced issues like the structure of protein molecules.

It is the use of engineering to form a simulated atmosphere. In contrast to traditional user interfaces, VR places the user within associated expertise. Rather than viewing a screen ahead of them, users are immersed and able to act with 3D worlds. By simulating as several senses as potential, like vision, hearing, touch and also even smell. The PC is remodeled into a gatekeeper to the present artificial world. The sole limits to near-real VR experiences are the provision of content and low-cost computing power.

History Of VR | Overviewvirtual reality history

  • In the mid-1400s “VIRTUAL” means “being something in essence or effect, though not actually or in fact
  • In 1938, French avant-garde playwright Antonin Artaud described the illusory nature of characters and objects in the theatre as “la réalité virtuelle” in a collection of essays, Le Théâtre et son double. The English translation of this book, published in 1958 as The Theater and it’s Double. It is the earliest published use of the term “virtual reality“.
  • The term “artificial reality“, coined by Myron Krueger, has been in use since the 1970s.
As we know that the exact origins of virtual reality, is disputed still we can see few footprints of the VR. Virtual reality has a long and very rich history. Below are a few of the interesting highlights.

Year Wise Evaluation of Virtual Reality

History of Virtual Reality before 1950

  • Early 1860:- Elements of Virtual Reality appeared
  • In 1890:- Thomas Edison and his assistant William Dickson pioneer the Kinetograph (a camera for recording pictures) and Kinetoscope (a projector for playing them back)—in effect, the first one-person “movie experience.”
  • In 1895:- French brothers Auguste and Louis Lumière have opened a primary movie theater in Paris, France. Legend has it that one of their picture show shorts. The arrival of a Train at La Ciotat is such a convincing depiction of reality that folks within the audience scream and run to the rear of the area.
  • In 1929:- Edwin link has developed Pilot Maker, also known as Link Trainer. It was a mechanical airplane simulator. His work pioneers the field of flight simulation.

History of Virtual Reality between 1950 to 1962

  • In 1950:- US Air Force psychologist James J. Gibson has published an influential book, The Perception of the Visual World. The book described how people see and experience things as an “optic flow” as they move through the world. These ideas, and those of contemporaries such as Adelbert Ames, help to form the foundations of the 20th-century psychology of visual perception, which feeds into academic studies of computer vision and virtual reality.
  • 1956:- Cinematographer Morton Heilig begins developing machines that can produce artificial sensory experiences.
  • 1957:- Morton Heilig has developed a pioneering 3D head-mounted display.
  • 1961:- C. Comeau and J. Bryan developed the first real head-mounted display, Head-Sight.
  • 1962:- Morton Heilig granted a patent for a machine called the Sensorama (a kind of updated, highly sophisticated Kinetoscope). That can immerse its user in artificial vision, sound, smell, and vibration. As a result, many people regard Heilig as the true father of virtual reality, though he has seldom been acknowledged as such.

History of Virtual Reality between 1962 to 1979

  • 1962:- Ivan Sutherland, the pioneer of human-computer interaction, develops the lightpen and a program called Sketchpad. That allows people to draw on a computer screen. It opened the way for the kind of computer graphics later used in virtual reality.
  • 1965:- The Ultimate Display by Ivan Sutherland.
  • 1968:- Ivan Sutherland and Bob Sproull (Sutherland’s understudy) made the absolute first VR/AR head-mounted showcase (Sword of Damocles). It was coupled to a PC TX-2. The gadget was crude both as far as authenticity and UI. Produced illustrations of Sutherland’s framework were basic wireframe rooms and items. These items have appeared at the stereoscopic presentation
  • 1970:- Computer scientist Myron Kreuger has opened a pioneering VR laboratory.
  • 1975 to 1976:- Will Crowther developed Adventure, it’s also called Colossal Cave Adventure. A highly influential, a text-based computer game in which players explore a virtual world, solving problems through a question and answer dialog.
  • 1977:- Dan SandinRichard Sayre, and Thomas Defanti made the first dataglove.

History of Virtual Reality between 1980 to 1990

  • The 1980s:- 3D graphics computer workstations, notably those developed by Silicon Graphics Inc. (later rebranded SGI, historically known as Silicon Graphics Computer Systems or SGCS), accelerate the development of scientific visualization, visual computer modeling, CGI movies, and VR.
  • 1982:- Tron (American Science fiction action-adventure film), a pioneering CGI movie, tells the story of a software engineer (played by actor Jeff Bridges AKA Jeffrey Leon Bridges) who ventures into the software of a mainframe computer.
  • 1983:- Computer scientist Myron Krueger coins the term “artificial reality“.
  • 1983:- Writer William Gibson coined the related term “cyberspace”
  • 1989:- Computer scientist and musician Jaron Lanier also known as Jaron Zapel Lanier, coined the now preferred term “virtual reality.” His company, VPL Research, garners huge media attention and develops pioneering VR peripherals, including a Head-Mounted Display and dataglove. Lanier has been popularly referred to as the “father of virtual reality“.

History of Virtual Reality between 1990 to 2000

  • 1992:- The Lawnmower Man, another influential VR film came in. Based on a Stephen King story and partly inspired by the story of VPL.
  • 1993:- Miller brothers Robyn and Rand Miller designed Myst, which was a computer game. It was an extremely successful graphical computer game, in which players explore an island in non-immersive virtual reality.  Cyan, Inc. has developed it and published by Brøderbund and released as a PC game for the Macintosh platform in 1993. In the game, players are told that a special book has caused them to travel to Myst Island. There, players solve puzzles and, by doing so, travel to four other worlds, known as Ages. These Ages reveal the backstory of the game’s characters.
  • 1994:- Dave Raggett, an influential English computer specialist coins the term VRML (Virtual Reality Markup Language). He had also played a key role in the development of the World Wide Web,
  • 1999:- The Matrix, another movie based on virtual reality, grosses over $450 million at the box office.

After 2000 (21st Century)

  • 2011:- Palmer Luckey develops the Oculus Rift, an inexpensive homemade HMD. He developed this head-mounted display in his parents’ garage.
  • 2014:- Facebook announces its acquisition of Oculus in a deal worth $2 billion.
  • 2016:- Oculus begins shipping its Rift headsets to customers. Meanwhile, a variety of smartphone makers produce rival VR systems, VR also appears for PlayStation, and Google announces that it has shipped over 5 million cardboard head-mounted displays for smartphones.
  • 2017:- Sony reveals that it sold 4.2 million PlayStation VR headsets in their first four months on the market.
  • 2018:- First Mind-controlled Virtual Reality Game. Neurable announces a “brain-scanning” headband with built-in electrodes that gives hands-free control of virtual reality.

Understanding Virtual Reality

If we’re going to understand why books, movies, paintings, and pieces of music aren’t the same thing as virtual reality, we need to define VR fairly clearly. For the purposes of this simple, introductory article, I’m going to define it as:

A credible, interactive 3D computer-created world that you can explore and you’re feeling you actually are there, by both mentally and physically.

Tech Exposer

Putting it in another way, in other words, or in points, virtual reality is actually:

  1. Believable: You really need to feel like you’re in your virtual world (on any other planet, or wherever) and to keep believing that, or the illusion of virtual reality will disappear.
  2. Interactive: As you move around, the VR world needs to move with you. You can watch a 3D movie and be transported up to the Moon or down to the seabed—but it’s not interactive in any sense.
  3. Computer-generated: Only powerful machines, with realistic 3D computer graphics, are fast enough to make believable, interactive, alternative worlds that change in real-time as we move around them.
  4. Explorable: A VR world needs to be big and detailed enough for you to explore. However realistic painting is, it shows only one scene, from one perspective. A book can describe a vast and complex “virtual world,” but you can only really explore it in a linear way, exactly as the author describes it.
  5. Immersive: To be each presumptive and interactive, VR must interact with both your body and your mind. Paintings by war artists will provide us glimpses of conflict. However, they’ll ne’er absolutely convey the sight, sound, smell, taste, and feel of a battle. You’ll be able to play a simulator game on your home computer and be lost in a {very} very realistic, interactive expertise for hours (the landscape can perpetually modification as your plane flies through it). However, it is not like employing a real trainer (where you sit during a hydraulicly operated mockup of a true cockpit and feel actual forces because it tips and tilts), and even less like flying a plane.

Summary

Above all, we can see from this why reading a book, observing a painting, paying attention to a classical symphony, or looking at a film does not qualify as virtual reality. All of them provide partial glimpses of another reality. However, none are interactive, explorable, or absolutely credible. If you are sitting during a movie show viewing a large image of Mars on the screen, and you suddenly flip your head too far, you’ll see and keep in mind that you are truly on Earth, therefore the illusion will disappear.

If you see one thing attention-grabbing on the screen, you cannot reach out and touch it or walk towards it. Once more, the illusion can merely disappear, therefore these kinds of recreation are primarily passive but plausible they may be. They do not actively have interaction you in any manner.

Conclusion

VR is totally different. It causes you to assume you’re truly living within a totally credible virtual world (one during which, to use the technical jargon, you’re partially or absolutely immersed). It’s two-way interactive: as you answer what you see, what you see responds to you. If you switch your head around, what you see or hear in VR changes to match your new perspective.
