Virtual Reality

Pose tracking and 3D near-eye displays are used in virtual reality (VR) to provide users an immersive sense of a virtual world. Virtual reality has applications in business, education (such as medical or military training), and entertainment (especially video games) (such as virtual meetings). Aside from virtual reality, other different forms of technology include augmented reality and mixed reality, sometimes known as extended reality or XR, however definitions are still evolving as the field develops.

To provide lifelike visuals, sounds, and other sensations that mimic a user's physical presence in a virtual world, current standard virtual reality systems either use virtual reality headsets or multi-projected environments. A user can see around the virtual world, move around in it, and interact with virtual features or objects while utilising virtual reality technology. The impression can also be produced by specially built rooms with numerous large screens, although it is most frequently produced by VR headsets that have a head-mounted display with a small screen in front of the eyes. Virtual reality normally includes audio and visual feedback, but haptic technology may also enable additional types of sensory and force feedback.

Since the middle of the fourteenth century, the word "virtual" has meant "being something in essence or effect, if not truly or in fact." [2] Since 1959, the word "virtual" has been used to refer to something that is "not physically existing but made to appear by software" in a computer context. [2]

In a collection of writings titled Le Théâtre et son double, French avant-garde playwright Antonin Artaud referred to the deceptive nature of people and things in the theatre as "la réalité virtuelle." The word "virtual reality" was first used in a published work in 1958 when The Theater and its Double, the English translation of this book, was released[3]. Since the 1970s, people have been referring to Myron Krueger's term "manufactured reality." Virtual reality was first mentioned in a science publication.
