Virtual Reality (VR) is a technology that involves the use of computer modeling and simulation to create an artificial three-dimensional (3-D) visual or another sensory environment. It allows a person to interact with this environment in a seemingly real or physical way, typically by using special electronic equipment such as a helmet with a screen inside or gloves fitted with sensors.
The user becomes part of this virtual world or is immersed within this environment and while there, is able to manipulate objects or perform a series of actions. The user’s actions partially determine what happens in the environment.
Unlike Augmented Reality (AR), which enhances the real world with digital elements, VR completely replaces the user’s real-world environment with a simulated one.
VR has found applications in various fields such as gaming, training and education, and virtual tours among others.
