How does virtual reality (VR) work?

Virtual reality (VR) works by using a headset that covers the eyes and often includes headphones to provide an immersive experience. The headset displays a 3D environment that responds to the user’s movements, creating the illusion of being in a different place. Sensors track the user’s head and body movements, allowing them to look around and interact with the virtual world in a natural way.
