AR overlays real-time 3D-rendered graphics onto the real world, integrating virtual content with the user’s physical environment.
Augmented reality (AR), also closely associated with mixed reality (MR), is a form of 3D human–computer interaction that overlays real-time, computer-rendered graphics onto the user’s view of the physical world. The result is an experience that is seamlessly integrated with the real environment, changing how users perceive what is around them. Unlike virtual reality, which replaces the real world with a fully simulated one, AR adds virtual information on top of what the user can already see. AR is typically visual, but it can involve multiple senses such as audio and haptics. A common core definition describes AR systems as combining (1) real and virtual elements, (2) real-time interaction, and (3) accurate 3D registration so virtual objects align correctly with real-world positions. Depending on the design, the overlaid information can be additive (constructive) or can obscure parts of the natural environment (destructive).
AR overlays real-time 3D-rendered graphics onto the real world, integrating virtual content with the user’s physical environment.
A core AR system combines real+virtual worlds, real-time interaction, and accurate 3D registration for correct spatial alignment.
AR differs from VR because the real environment remains present, with virtual objects added rather than fully replacing reality.
A technology that overlays real-time computer-generated 3D graphics onto the user’s view of the real world so virtual information is integrated with the physical environment.
The process of accurately aligning virtual objects with real-world geometry and positions in space.
User and system responsiveness that updates the AR content immediately as the user moves or interacts.
AR overlays can either add information to the natural scene (constructive) or mask parts of it (destructive).
A broader term often used alongside AR, describing systems that blend real and virtual elements, sometimes emphasizing interaction and physical integration.
