Augmented reality (.AR) is the real-time use of information in the form of text, graphics, audio and other virtual enhancements integrated with real-world objects. It is this "real world" element that differentiates AR from virtual reality.

Augmented reality is an interactive experience in which a real-world environment is enhanced with computer-generated visual elements, sounds, and other stimuli. It can provide a user with a heightened, more immersive experience than they would experience otherwise, which adds to the user's enjoyment or understanding. From a commercial perspective, augmented reality can increase brand awareness and boost sales.

Since augmented reality uses a real-world environment in conjunction with computer-generated visual elements, it may be seen as more realistic than virtual reality, which is 100% computer-generated. However, advances in technology mean that even entirely virtual environments can seem fully realistic. 

It can be used in everything from gaming and design to shopping and education. It is a form of mixed reality, combining the real world with digital visual elements, as opposed to virtual reality, which is entirely digital.
