Virtual Reality (VR) is the use of computer technology to create a simulated environment. Unlike traditional user interfaces, VR places the user inside an experience. Instead of viewing a screen in front of them, users are immersed and able to interact with 3D worlds. By simulating as many senses as possible, such as vision, hearing, touch, even smell, the computer is transformed into a gatekeeper to this artificial world. VR is technology that allows you to engage in simulated spaces with sounds and images to replicate an immersive 3D environment. VR simulation may replicate current or past live environments or create something totally new.
