Conclusion
What is Augmented Reality?
Augmented Reality is a field of

computer research which deals
with combination of reality
with computer generated data.

It is still in an early stage of

research and development.
possibly by the end of this
decade.
Augmented Reality System
An augmented reality system is one that
•Combine real and virtual world.
•Is interactive in real time.
•Is registered in 3D.
Augmenting Our World
The basic idea of augmented

reality is to superimpose
graphics, audio and other sense
enhancements over a real-world
environment .
These systems display graphics
for only one point of view. Nextgeneration augmented-reality
systems will display graphics for
each viewer's perspective.
Software based on Augmented
Reality …
1.Wikitude – wiki attitude
WIKITUDE World Browser

presents the user with data about
their surroundings, nearby
landmarks, and other points of
interest by overlaying information
on the real-time camera view of a
smart-phone.
2.Barcode Scanner

We can scan a barcode from a product.
The details related that product

will be displayed on your phone.
Implementation:To implement there are four things
find user’s location
find user’s orientation (view)
generating information
augmenting it to user’s view.
Generate data
Find user’s location

Find user’s orientation (view)

Augment generated
data to user’s view
Components:• Display
• Tracking system such as GPS
• Mobile computing
Head-mounted Displays(HMD’s)
Just as a monitor allow us to see

text and graphics generated by
computers.

Head-mounted displays (HMDs)

will enable us to view graphics
and text created by augmentedreality systems.
Tracking and Orientation
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 users' eyes and heads.
AR System needs to know two things

1.Where the user is located

2.Where he is looking
Digital compass
A digital compass consists of

sensors to measure the earth's
magnetic field, some conditioning
of those sensor signals, and a
microcontroller to interpret the
data
Mobile Computing Power
Wearable computers.
Mobile computing can be accomplished with help of

wearable computers.

A wearable computer is a battery powered computer

system worn on the user’s body(belt etc).
Applications:-

Education
In an Augmented Reality interface students can

be seated around a table and see each other at
the same time as a virtual heart floating in their
midst.
This results in conversational behavior that is

more similar to natural face-to-face collaboration
than to screen based collaboration.
Military
The military also uses augmented reality for decades.

The idea here is that an augmented-reality system could
provide troops with vital information about their
surroundings, such as showing where entrances are on
the opposite end of the building, somewhat like X-ray
vision.

Augmented reality displays

could also highlight troop
movements and give soldiers
the ability to move to where
the enemy can’t see them.
Gaming
 How cool would it be to take video games outside?
The game could be projected onto the real world around

you.

One Australian researcher has created a prototype game

that combines Quake, a popular video game, with
augmented reality. He put a model of a university
campus into the game's software. Now, when he uses
this system, the game surrounds him as he walks across
campus.
Limitations:Accurate tracking and orientation
Conclusion:Augmented reality will further blur the line between

what's real and what's computer-generated by
enhancing what we see, hear, feel and smell.
