  3. 3. Augmented Reality ?? Augmented reality (AR) is a live, direct orindirect, view of a physical, real-world environment whoseelements are augmented by computer-generated sensory inputsuch 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 thephysical and interactive real world . Dept. of CSE, RVCE 3
  4. 4. Chronicles of Augmented Reality1962: Morton Heilig creates Sensorama1966: Ivan Sutherland invents the head-mounted display1975: Myron Krueger creates Videoplace1990: Tom Caudell coins the phrase Augmented Reality2005: Camera system developed that can analyze physical environments in real time2008: AR apps make an entry in Smartphone market * Source : and Dept. of CSE, RVCE 4
