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
