Virtual reality (VR) is a simulated experience that is created using a combination of technologies such as computer graphics, audio, and interactive input devices. It gives users the opportunity to experience and interact with a 3-dimensional, computer-generated environment, which can include realistic images, sounds, and other sensations that simulate a physical presence in a different space. By immersing users in realistic virtual worlds, VR provides a highly engaging experience that allows users to explore and interact with their environment.
