Virtual Reality (VR) puts you inside a fully digital, computer-generated world using a headset. Augmented Reality (AR) adds digital objects on top of the real world you can still see — like a game character appearing on your kitchen table through your phone.
How does it work?
Headsets and phones use cameras, sensors, and displays to track your movement and surroundings. VR replaces your entire view with a 3D environment, while AR overlays digital images onto the real one in the correct position.
Why does it matter?
AR and VR change how we learn, work, and play by making digital content feel more real and interactive. They allow experiences that would be impossible, dangerous, or expensive in real life.
