What is Augmented Reality?
• AR is a digital overlay of information over a live camera view of the real world• Enhances reality with digital information about the images that appear
on the screen
• AR is frequently used due to the development of camera recognition software• Glasses
• Virtual retina displays
• Camera phones
Augmented Reality Market
• Total value of AR mobile market in 2009 was $130,000
• AR capable smartphones increased from 8 million in 2009 to more than 100 million in 2010
• Late 2010 saw exponential growth from 2009 • Value in 2010 was $1.5 million
• Forecasts for 2015 expect $1.5 billion
• In the next five years expected to grow
at an average of 239% per year

Augmented Reality Classification
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
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
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
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
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
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
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
Case Study: Augmented Reality and CTAR
Approach
• 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
Case Study: Augmented Reality and CTAR
Results
• Each stop box displays:• Distance to the station
• Station's 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
Case Study: Augmented Reality and CTAR
How 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
