Augmented reality (AR) is believed to enhance and expand your view of the real world with computer-generated outputs, including sound, video, graphics, or GPS data. The discussion around augmented reality became obvious when Google Glass was launched a few years back. Most recently Pokemon Go again created buzz around augmented reality. AR has exciting implications for everything from education, defense, healthcare, and advertising, to construction, automotive, games, and much more.
1. AR has a long history: As far back as 1957, there was a machine called the Sensorama (see below). It blew wind on you and vibrated the seat you sat on and immersed you in 3D film with stereo sound. In 1966, Ivan Sutherland invented the head-mounted display, which augmented real-world perspectives with computer data. The technology was first named “augmented reality” by Tom Caudell, a Boeing researcher who used it to describe displays that blended virtual graphics onto a physical reality in order to help aircraft electricians do their work.
2. AR is happening now: As noted above, augmented reality has been around in one form or another for almost 50 years, but is now fueled by computing and sensory technology that has improved 1000-fold in cost/performance in the past decade. AR is already in wide use today, for all kinds of mundane but important tasks.
