CONTENTSo Augmented Reality.o Augumented reality vs virtual realityo Components used in Augmented Reality system.
Head Mounted Display. Tracking System. Mobile Computing Power.
o Applications.o Disadvantageso Scope in future.o Conclusions and References.
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.
Augmented Reality•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

SENSORS
o GPS sensorso Solid State Compasso Accelerometero Gyroscopeso 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)

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
• Measured location may not be accurate.• May cause visible registration error.• Environment may be cluttered with information and become unreadable.• Real time rendering problems.
Visualization Problems:

SCOPE IN THE FUTURE • Enhanced media applications ,like pseudo
holographic virtual screens, virtual surround cinema.
• Replacement of cell phones: eye dialing, insertion of information directly into environment.
• You may learn things about the city you've lived in for years just by pointing your AR-enabled phone at a nearby park or building.

CONCLUSION Augmented reality will further blur the line
between what's real and what's computer generated by enhancing what we see, hear, feel. It has possibilities beyond our imagination and perception. It will have huge applications in almost every field.
