3. Augmented Reality ??
Augmented reality (AR) 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 has been defined as combining real and computer-
generated digital information into the user’s view of the
physical and interactive real world .

4. Chronicles of Augmented Reality
1962: Morton Heilig creates Sensorama
1966: Ivan Sutherland invents the head-mounted display
1975: Myron Krueger creates Videoplace
1990: Tom Caudell coins the phrase Augmented Reality
2005: Camera system developed that can analyze
physical environments in real time
2008: AR apps make an entry in Smartphone market
