3. Evolution of Augmented Reality 1968:  Ivan Sutherland, a Harvard professor and computer scientist, created the first head-mounted display called ‘The Sword of Damocles ’. 1974:  Myron Kruger, a computer researcher and artist, built a laboratory at the University of Connecticut called ‘ Videoplace ’ that was entirely dedicated to artificial reality.  1990:  Tom Caudell , a Boeing researcher, coined the term ‘augmented reality ’. 1992:  Louis Rosenburg , a researcher in the USAF Armstrong's Research Lab, created ‘Virtual Fixtures’, which was one of the first fully functional augmented reality systems . 1994:  Julie Martin, a writer and producer, brought augmented reality to the entertainment industry for the first time with the theater production titled Dancing in Cyberspace. 1998:  Sportsvision broadcasts the first live NFL game with the virtual 1st & Ten graphic system – aka the yellow yard marker. The technology displays a yellow line overlayed on top of the feed to that views can quickly see where the team just advance to to get a first down . 1999:  NASA created a hybrid synthetic vision system of their X-38 spacecraft. The system leveraged AR technology to assist in providing better navigation during their test flights . 2000:  Hirokazu Kato developed an open-source software library called the  AR Toolkit . This package helps other developers build augmented reality software programs. The library uses video tracking to overlay virtual graphics on top of the real world . 2003:  Sportvision enhanced the 1st & Ten graphic to include the feature on the new Skycam system – providing viewers with an aerial shot of the field with graphics overlaid on top of it .

Continued…. 2009:  Esquire Magazine used augmented reality in print media for the first time in an attempt to make the pages come alive. 2013:  Volkswagen debuted the MARTA app (Mobile Augmented Reality Technical Assistance) which primarily gave technicians step-by-step repair instructions within the service manual 2014 :  Google unveiled its Google Glass devices, a pair of augmented reality glasses that users could wear for immersive experiences . Users wore the AR tech and communicated with the Internet via  natural language processing  commands. With this device, users could access a variety of applications like Google Maps, Google+, Gmail, and more . 2016:  Microsoft starts shipping its version of wearable AR technology called the HoloLens, which is more advanced than the Google Glass, but came with a hefty price tag. It’s definitely not an everyday type of accessory . 2017:  IKEA released its augmented reality app called IKEA Place that changed the retail industry forever .

5. How It Works? The basic idea of augmented reality is to superimpose graphics, audio and other sense enhancements over a real-world environment in real-time. The graphics will then change to accommodate the user’s eye or head movements. To implement augmented reality there are three things are required. Find user’s location Find user’s orientation Generating information

6. Components of Augmented reality Display – To see text and graphics generated Tracking System- To know where the user is located Mobile Computing Power- To generate text or graphics

9. 2. TRACKING SYSTEM The biggest challenge facing developers of augmented reality is the need to know where the user is located in reference to his or her surroundings. There’s also the additional problem of tracking the movement of user’s eyes and heads. AR System needs to know two things:- Where the user is located Where he is looking

10. GPS-Tracking Technologies Currently, the best tracking technology available is the global positioning system. However , GPS
