What is VR / AR ?


2 min read

Virtual reality (in short VR) is a simulation of an environment, as full as possible, through a computer, smartphones and now even in ALL IN ONE devices inside the glasses the computer creates an illusion of a realistic environment. Some virtual reality systems simulate the entire space in which the user is in a different environment and some of them only simulate the computer and its environment close to some other environment. Virtual reality is used for entertainment, study, and training.


The simulated environment can simulate an environment that actually exists in the real world outside the computer room, such as simulations for pilots or combat training, or simulate a completely imaginary environment.


The virtual virtual reality world is gaining momentum, and today the virtual reality experience can be obtained in 3 main ways. One by using a smartphone, computer or mobile virtual reality glasses, such as vive focus and of course oculus go and quest.


Jaron Lanier coined the term "virtual reality or virtual reality" in 1989. Lanier was one of the pioneers in the field when he founded VPL Reasearch (Virtual Programming Languages), which built some of the first systems in the 1980s. The term "Artificial Reality" was used in the 1970s and cyberspace since 1984. The virtual reality system and hypermedia (hypermedia = a system in which various media are linked by hypertext software so that the user can move between them in a non-linear way, such as the use of internet links) was the Aspen Movie Map created at MIT in 1977 with DARPA funding. The rough city of Aspen in Colorado, and the user could roam its streets in three states: summer, winter, and polygynous. In were based on photographs taken by developers through the city in two seasons, and the third was a very rough model three-dimensional city.


Originally, the term virtual reality came to represent a complete system that creates the illusion of copying elsewhere, but some also use the term to describe systems where there are no measures like cyber gloves, etc., such as VRML on the Internet, and sometimes text-based interactive systems such as MOO and MUD systems. Systems that do not simulate copying elsewhere use a standard screen, and some joystick. This use of the term is controversial.


The term is an oxymoron.


The virtual reality world is changing and evolving, and in 2015, Facebook acquired the $ 2 billion startup Oculus. This company has developed advanced virtual reality glasses for Daz. This was the opening whistle for huge competition in the industry, where huge companies such as: Google, HTC, Sony, Microsoft and Samsung and many others began investing and developing virtual reality glasses in billions of dollars. Google has taken a bit of gear off of it right now and invested in software development but their Google Cardboard, a virtual cardboard virtual reality glasses called Google cardboard, thus making the virtual reality experience accessible to the masses, at a low cost.


Another breakthrough in virtual reality is the growing use of 360-degree photo technology, especially by the support of video giants - Facebook and Google (YouTube). This way of photography and the use of virtual reality glasses - the audience will have the option of "feeling inside" the videos, which will give a new and refreshing volume to the web-distributed videos.
