Augmented Reality

Augmented reality, also known as mixed reality, is a form of three dimensional human-computer interaction that overlays real-time computer-rendered graphics into the real world through a display, such as a handheld device or a head-mounted display, so the experience is perceived as an immersive part of the physical environment. It alters a person's ongoing perception of a real-world environment, in contrast to virtual reality, which aims to replace the user's real-world environment entirely with a simulated one; augmented reality is typically visual but can span other sensory modalities, including auditory, haptic and somatosensory.
