What is augmented reality (AR)?

Augmented reality (AR) is the technology that integrates virtual elements into physical environments. It layers images, sound, and text on real-world surfaces. AR alters users' perception of the real-life environment — or augments it. The most common examples are video games like Pokemon Go or Snapchat filters.

To qualify as augmented reality, the technology must be interactive — i.e., it should respond to user input and account for changes to the environment. For example, a filter might change when a user opens their mouth and have a butterfly emerge out of it on the screen.

There are two main ways to deliver augmented reality:

• Mobile augmented reality (MAR) is experienced on mobile devices like smartphones and tablets.
• AR glasses are a wearable smart display with a see-through viewing experience.
