What is Virtual Reality or VR?

Computer-generated simulation technology that depicts a fictional real-world environment is a virtual reality or VR technology.

VR technology is related to the game world.

What is Virtual Reality?

Citing the University of Toronto Libraries page,

virtual reality (VR) uses computer technology to create a simulated environment that can be explored in 360 degrees.

This use of computer modeling and simulation allows a person to visually interact with an artificial three-dimensional (3D) or other sensory environment.

VR technology is like immersing the user in a computer-generated environment that simulates reality through the use of interactive devices.

The device sends and receives information that is used, such as glasses and earbuds (headset).

Quoting Britannica, there is an illusion of telepresence that is influenced by motion sensors.  It captures the user's motion and adjusts the display on the screen.

Usually in real time or when the movement occurs at the present time.  The purpose of VR is to provide a virtual environment for humans to interact with computers,

but as if done in the real world.  For example, communicating virtual through spoken language, writing, or by drawing.

Citing Science Direct, virtual reality technology plays an important role in realizing telesensation.
