The term augmented reality was first coined in 1992 [00:05]: by Thomas Caudell and David Mizell, two Boeing engineers working on a simple [00:10]: see-through headset that aided airplane engineers in complex wiring schematics. [00:15]: According to their documentation, the goal of augmented reality, commonly [00:20]: abbreviated as AR, was to enable cost reductions and efficiency improvements, [00:26]: and many of the human-involved operations and aircraft manufacturing. [00:33]: We've been dreaming about the potential of AR for a long time, [00:36]: and the history of the medium stretches back before we even had a term for it. [00:41]: In fact, AR shares a history [00:44]: with its technological cousin, virtual reality, both virtual reality [00:51]: or VR and AR share a common [00:53]: ancestor, the Sword of Damocles. [00:57]: Built in 1968, the Sword of Damocles was created [01:00]: by a computer scientist and researcher, Ivan Sutherland. [01:02]: His goal was to create the ultimate display, [01:06]: a digital interface capable of transforming the physical world. [01:11]: The prototype was so heavy [01:15]: it needed to be suspended from the ceiling by a mechanical arm. [01:18]: For all that hardware, it could only display basic wire [01:21]: frame rooms that were barely explorable. [01:24]: But it was one of humankind's first experiments [01:27]: into replacing your real world with a digital reality.
