In order to be considered a truly augmented reality application, an app must
interactively attach graphics or data to objects in real time, to achieve the real and
virtual combination of graphics into the physical environment:
An AR system supplements the real world with virtual (computer-generated) objects that
appear to coexist in the same space aS the real world. AR can potentially apply to all sense,
including hearing, touch, and smell (Azuma et al, 2001, p. 34).
