  8. 8. Augmented Reality Classification
  9. 9. History of Augmented Reality• One of the first augmented reality systems was created in 1992 • Virtual Fixtures was developed at the U.S. Air Force Research laboratory• First Augmented Reality mobile device debuted in 2008 • Wikitude AR Travel Guide launched on the T-Mobile G1 Android phone• Video games featured Augmented Reality cards to play with the device camera • Nintendo 3DS and Playstation Vita feature this application• Recently gained popularity in smart phones
  10. 10. Phone Requirements• A way to determine location • Phone provides that through GPS and an internal compass • iPhone has gyroscopes• A method of downloading data • Provided through mobile broadband connection• Powerful graphics processing capabilities • Camera phone in the case of smartphones• A processor and display
  11. 11. Dataset Requirements• Location-based • Data points need to be tied to a specific location• User interest in daily life • Needs to be a data set that users would be interested in looking up• Publicly available data • Or privately held data that can be shared with Promet • Data needs to be accessible online
  12. 12. Outlook on Augmented Reality• Analysts predict every smart phone will feature an augmented reality application by 2014• Augmented Reality can generate $1.5 billion by 2015 • Other analysts predict $5.1 billion by 2016 • Future developments: using cloud data to enhance the information in AR• Expected to rise from 0.1% of the market to 1.0% of the market in the next five years
  13. 13. Augmented Reality Capabilities• Public Transportation • Tracking the nearest train and buses and the frequency they are coming in• College Campus Tours • Allow users to point their phones at campus buildings and conduct a self-guided tour• Museum Guides • Allow users to gain background information about a piece of art by pointing your phone• Restaurant Guides • Find the best restaurants and ratings nearby• Real Estate • Look at houses that are sale in a neighborhood with your mobile phone
  14. 14. Augmented Reality Capabilities• Architecture Tours • Learn about the history of each building by merely pointing your phone• Commercial Tourism • Explore a city’s most famous attractions with your phone• Meetups/Conferences • Find the nearest conference in a city block• Concerts • Check out the concerts in your neighborhood by pointing your phone
  15. 15. Case Study: Augmented Reality and CTAR Challenge • Needed a way to consolidate CTA info and display it in relation to its surroundings • Augmented Reality software was traditionally used in video games • Had to account for over 30,000 bus stops, as well as train lines • Needed to show whether the bus of train was Northbound or Southbound
  16. 16. Case Study: Augmented Reality and CTARApproach• Used program to determine coordinates and orientation of phone• App uses floating point arithmetic to compare the location of the user with the location of each bus stop• Separated bus and train information into separate tables to prevent slowdowns
  17. 17. Case Study: Augmented Reality and CTAR Results • Each stop box displays: • Distance to the station • Stations name • Color of lines passing through • ETAs of trains in all directions • App allows you to tap whichever line you are interested in within a station
  18. 18. Case Study: Augmented Reality and CTARHow the CTAR works• CTAR uses the GPS and Compass to provide and accurate location of the phone and where it is pointed• Accelerometer used to determine whether the phone is tilted at a specific angle• CTAR downloads location and arrival times from Chicago Transit Authority in real time • Needs to sort through data tables to retrieve names, id and geo- coordinates• Displays the nearest stop and arrival time
