  Definition by Ron Azuma
0 To avoid limiting AR to a specific technology,
  AR system should have the following
 characteristics:
  0 Combines real and virtual elements
  0 Interactive in real time
  0 Registered in 3D
              Definition
0 Augmented reality (AR) is a term for a
 live direct or an indirect view of a
 physical, real-world environment
 whose elements are augmented by
 computer-generated sensory input, such
 as sound or graphics.
