Augmented reality, often abbreviated AR, overlays computer-generated content, such as images, information, or interactive graphics, onto a live view of the real world in real time, typically through a smartphone camera, tablet, or specialized headset.

Unlike video editing that adds effects to pre-recorded footage, AR content is generated and positioned dynamically as the device tracks its surroundings, allowing digital objects to appear to interact with real physical space as the user moves.

Overlaying Digital Content on the Real World

AR vs VR: The Key Difference

The key distinction from virtual reality is that AR adds to the real world rather than replacing it β€” VR immerses a user in a fully simulated environment that blocks out physical surroundings, while AR keeps the real environment visible and simply layers digital elements onto it.

Common real-world uses include navigation apps that overlay directions onto a live camera view, furniture shopping apps that show how an item would look in your actual room, and industrial applications where technicians see repair instructions overlaid directly onto the equipment they're working on.
