By now, most educators are familiar with augmented reality (AR) and its application in the classroom. And as it grows in popularity, its potential in the classroom grows, too.

Augmented reality overlays digital information on top of an existing environment, and the AR device market is expected to reach more than $659 million by 2018, according to an infographic that analyzes AR’s potential for the classroom.

Fun fact: One of the first commercial applications of AR technology was the yellow first down line that started appearing in televised NFL games in the late 1990s.

Google glass and heads-up displays in car windshields are probably the most well-known consumer AR products, but the technology is used in other industries, such as marketing, health care, tourism and public safety.

But AR also can make learning more engaging.
