Augmented Reality (AR)

Augmented Reality (AR) modifies a real-world environment with music, visuals, or other inputs.

Snippet from Wikipedia: Augmented reality

Augmented reality (AR), also known as mixed reality (MR), is a form of 3D human–computer interaction that overlays real-time 3D-rendered computer graphics into the real world through a display, such as a handheld device or head-mounted display. This experience is seamlessly interwoven with the physical world such that it is perceived as an immersive aspect of the real environment. In this way, augmented reality alters one's ongoing perception of a real-world environment, compared to virtual reality, which aims to completely replace the user's real-world environment with a simulated one. Augmented reality is typically visual, but can span multiple sensory modalities, including auditory, haptic, and somatosensory.

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. Air Force's Armstrong Laboratory in 1992. Commercial augmented reality experiences were first introduced in entertainment and gaming businesses. Subsequently, augmented reality applications have spanned industries such as education, communications, medicine, and entertainment.

Augmented reality frameworks include ARKit and ARCore. Commercial augmented reality headsets include the Magic Leap 1 and HoloLens. A number of companies have promoted the concept of smartglasses that have augmented reality capability.

Augmented reality refers to experiences that are artificial and that add to the already existing reality. In AR, information about the environment and its objects can be overlaid on the real world. This information can be virtual or real, e.g. seeing other real sensed or measured information such as electromagnetic radio waves overlaid in exact alignment with where they actually are in space. Augmented reality also has a lot of potential in the gathering and sharing of tacit knowledge.

Augmented reality 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. The overlaid sensory information can be constructive (i.e. additive to the natural environment), or destructive (i.e. masking of the natural environment).
