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 .

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

Resurrecting the ruins
Dept. of CSE, RVCE 15
Motivation Rich archeological remains, dating back to several
thousand years
Benefits Country’s culture and Heritage
Existing archaeology should not be disturbed
Source of Revenue
Enhances users perception of interaction with real world
Dept. of CSE, RVCE 16
Prior Art•Audio and Video CDs
•Virtual tour through websites and CD-ROMS
•Interactive Information Kiosks
•Audio guided tours
Drawbacks
i) Lack of Intelligence
ii) User friendliness
iii) Fails to provide accurate navigation
