Augmented reality (AR) is a type of interactive, reality-based display environment that takes the capabilities of a computer generated display, sound, text, and effects to enhance the user's real-world experience. Combines real and computer-based scenes and images to deliver a unified but enhanced view of the world.
Augmented reality, in computer programming, is a process of bringing together or “augmenting” video or photographic displays by superimposing the images with suitable computer-generated data. The earliest applications of augmented reality were almost definitely the “heads-up-displays” (HUDs) used in military airplanes and tanks, in which instrument panel-type information is projected against the same cockpit cover or viewfinder through which a crew member sees the external environments. Faster computer processors have made it feasible to integrate such data displays with real-time video.
