Wikipedia defines Augmented Reality (AR) as “a live direct or indirect view of a physical, real-world environment whose elements are augmented (or supplemented) by computer-generated sensory input such as sound, video, graphics or GPS data.” What is key here is the ‘live view’ of the real world. As opposed to the ‘Virtual Reality’ that has been a mainstay of science fiction for decades and is slowly finding its way into our living rooms, Augmented Reality superimposes information on top of a live view. At its simplest level, a common thermal camera with digital readings is a form of AR. At the opposite extreme are devices like the Heads-Up-Display (HUD) helmet used in the F-35 Lightning. The HUD layers all the complex information a fighter pilot operating near (or above) the speed of sound needs onto their real-world view through the visor, while clocking in at a hefty $400,000 for each unit.
