Augmented Reality

Augmented reality is “enhanced” reality. Augmented reality applications and devices
enhance our experience of the real world by altering or adding to how we see and hear it
around us. Augmented Reality is considered as an extension of Virtual Reality, and is a live,
direct or indirect, view of a physical, real-world environment whose elements are
augmented by computer-generated sensory input such as sound, video, graphics or GPS
data.
“AR is about augmenting the real world environment with virtual information by improving
people’s senses and skills. AR mixes virtual characters with the actual world. There are
three common characteristics of AR scenes: the combination of real world environment
with computer characters, interactive scenes, and scenes in 3D” Ronald Azuma, A Survey of
Augmented Reality Presence (Azuma, 1997; Azuma et al., 2001).
