This document provides an overview of augmented reality (AR). It defines AR as enhancing the real world with computer-generated sensory input like sound, graphics or GPS data. The document outlines the history of AR, compares it to virtual reality, describes typical AR system hardware and software components, and gives examples of AR applications in entertainment, industrial uses, and archaeological sites. It also discusses design challenges and next steps to developing an AR system for interacting with archaeological ruins.

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
