What Is Augmented Reality (AR)? 
• A combination of 
– a real scene viewed by a 
user and 
– a virtual scene 
generated by a 
computer that augments 
the scene with 
additional information.
Milgram’s Reality-Virtuality 
Continuum
AUGMENTED REALITY 
VIRTUAL REALITY 
Augmented Reality 
versus 
•System augments the real 
world scene 
•User maintains a sense of 
presence in real world 
•Needs a mechanism to 
combine virtual and real 
worlds 
•Hard to register real and 
virtual 
Virtual Reality 
•Totally immersive 
environment 
•Senses are under control of 
system 
•Need a mechanism to feed 
virtual world to user 
•Hard to make VR world 
interesting
TECHNOLOGY USED 
HARDWARE: The kind of hardware 
used is determined by the process for 
which the AR system is being developed. 
• Processor 
• Input Devices 
• Display Device 
• Sensors
HARDWARE 
[Contd.]
HARDWARE 
[Contd.] 
Displays: 
o HMDs 
o Hand-Held Devices 
o Glasses 
o Contact Lenses
HMDs 
US Airforce AR Simulation 
A person with VR HMD
Hand Held Devices
GLASSES 
Google Glass 
AR Glass Prototype
GLASSES 
[Contd.]
CONTACT LENSES 
iScan Lens
SENSORS 
o GPS sensors 
o Solid State Compass 
o Accelerometer 
o Gyroscopes 
o Proximity Sensors
SOFTWARE 
“How realistically well the software 
integrates the augmentation with the 
real world.” 
o Derive real-world coordinates through 
the images from camera. 
o The above process is called image 
registration. 
o The registered images are then 
mapped with relevant virtual data by the 
inbuilt computer. 
o Simultaneous Localization and 
Mapping (SLAM)
SOFTWARE 
[Contd.] 
o Augmented Reality Markup Language 
(ARML) [developed within the Open 
Geospatial Consortium (OGC)] 
o AR SDKs: 
o Metaio 
o Vuforia 
o Wikitude 
o Layar
Layar Webpage 
[ http://www.layar.com ]

APPLICATIONS OF 
AR 
• ARCHAEOLOGY 
• ARCHITECTURE 
• CONSTRUCTION 
• GAMING 
• NAVIGATION 
• SPORTS 
• MILITARY
ARCHAEOLOGY 
ARCHITECTURE 
GAMING EARTHMINE APP 
CONSTRUCTION
WAYS TO TRY AR YOURSELF: 
• Layar Browser 
• Google Glasses (App) 
• Google Glass 
• Copter Attack (Android Game) 
• Augment (Android App) 
• Nokia City Lens (Windows Phone)
PROBLEMS OF 
AR 
Visualization Problems: 
• Measured location may not be 
accurate. 
• May cause visible registration error. 
• Environment may be cluttered with 
information and become unreadable. 
• Real time rendering problems.
PROBLEMS OF 
AR 
Perceptual and Human Factors: 
• Depth perception 
• Adaptation 
• Fatigue and eye strain
