Definition

Virtual reality (VR) is a technology that creates an interactive virtual environment that can give the user the impression that they are in a different reality. This is achieved using specially designed devices such as VR headsets that provide a visual and audible feature to enable the user to see and hear the virtual world.

How was virtual reality invented?

The concept of virtual reality dates back to the 1960s, but technological advances in hardware and software have only allowed VR to become mass popular in recent decades. 

The first VR headsets (VR glasses) were large and heavy, but today’s modern VR devices are much easier and more accessible and offer high-quality visuals and sound.

How does VR work?

Virtual reality gives the user a 360-degree view of the virtual world through a screen in the headset. Sensors monitor the user’s movement and adjust the image to make it appear that the user is moving in this virtual environment. The sound element is also important and adds an overall impression of the experience.

What is virtual reality used for?

Virtual reality has a wide range of applications in different areas. It is used:

  • In the gaming industry, to create gaming experiences,
  • In medicine, for the simulation of surgical procedures and the training of doctors,
  • In the architecture for virtual building models,
  • In various forms of education and training, 
  • In the arts.

Example

One example of the use of virtual reality is ‘Oculus Quest‘ by Meta (formerly Facebook). This VR headset offers a wireless experience and is popular not only among players, but also among those who use it for virtual travel, education or even exercise.

Users can create their virtual environments, play games, or communicate with other users in the virtual world.
