AR Augmented Reality

Augmented reality (AR) is an interactive experience of a real-world environment where the objects that reside in the real world.Computer-generated perceptual information enhances perception, sometimes across multiple sensory modalities such as visual, auditory, haptic, somatosensory, and olfactory. AR is defined as a system that combines real and virtual worlds, allows for real-time interaction, and accurately registers virtual and real objects in 3D. The sensory information overlaid can be constructive (i.e. beneficial to the natural environment) or destructive (i.e. masking of the natural environment).

This experience is so intertwined with the physical world that it is perceived as an immersive aspect of the real world. In this way, augmented reality modifies one’s ongoing perception of a real-world environment, whereas virtual reality replaces the user’s real-world environment entirely with a simulated one. Augmented reality is related to two terms that are largely interchangeable: mixed reality and computer-mediated reality.

The primary value of augmented reality is the way in which digital world components blend into a person’s perception of the real world, not as a simple display of data, but through the integration of immersive sensations perceived as natural parts of an environment. The first functional AR systems that provided users with immersive mixed reality experiences were developed in the early 1990s, beginning with the Virtual Fixtures system developed in 1992 at the United States Air Force’s Armstrong Laboratory. Commercial augmented reality experiences first appeared in the entertainment and gaming industries.  As a result, augmented reality applications have spread into commercial sectors such as education, communications, medicine, and entertainment.Content in education can be accessed by scanning or viewing an image with a mobile device, or by using markerless AR techniques.

Augmented reality is used to improve natural environments or situations while also providing perceptually enhanced experiences. The information about the user’s surrounding real world becomes interactive and digitally manipulated with the help of advanced AR technologies (e.g., adding computer vision, incorporating AR cameras into smartphone applications, and object recognition). The real world is overlaid with information about the environment and its objects. This data could be virtual. Augmented Reality refers to any artificial experience that augments existing reality. or real, such as seeing other real sensed or measured data, such as electromagnetic radio waves, overlaid in exact alignment with where they are in space. Augmented reality has enormous potential for gathering and sharing tacit knowledge.

Augmentation techniques are typically used in real time, in semantic contexts, and with environmental elements. Immersive perceptual data is sometimes combined with supplemental data such as scores over a live video feed of a sporting event. This combines the advantages of augmented reality and heads-up display technology (HUD).
