Air Force's Armstrong Laboratory in 1992. The earliest functional AR systems that provided immersive mixed reality experiences for users were invented in the early 1990s, starting with the Virtual Fixtures system developed at the U.S. The primary value of augmented reality is the manner in which components of the digital world blend into a person's perception of the real world, not as a simple display of data, but through the integration of immersive sensations, which are perceived as natural parts of an environment.

Augmented reality is related to two largely synonymous terms: mixed reality and computer-mediated reality. In this way, augmented reality alters one's ongoing perception of a real-world environment, whereas virtual reality completely replaces the user's real-world environment with a simulated one. This experience is seamlessly interwoven with the physical world such that it is perceived as an immersive aspect of the real environment. additive to the natural environment), or destructive (i.e. The overlaid sensory information can be constructive (i.e. AR can be defined as a system that incorporates three basic features: a combination of real and virtual worlds, real-time interaction, and accurate 3D registration of virtual and real objects. Air Force, Wright-Patterson Air Force Base (1992)Īugmented reality ( AR) is an interactive experience of a real-world environment where the objects that reside in the real world are enhanced by computer-generated perceptual information, sometimes across multiple sensory modalities, including visual, auditory, haptic, somatosensory and olfactory.
