AUGMENTED REALITY
 Augmented Reality is a
field of computer research
which deals with
combination of reality
with the computer
generated data.
 The basic idea of
augmented reality is to
superimpose graphics,
audio and other sensory
enhancements over a real
world environment in real
Augmented-reality displays will
overlay computer-generated
graphics onto the real world.

AUGMENTED REALITY
 An augmented reality system generates a
composite view for the user. It is a
combination of the real scene viewed by the
user and a virtual scene generated by the
computer that augments the scene with
additional information.
 Augmented Reality(AR) is a combination of
three factors .These are :
Real and virtual world.
Interaction in the real time.
3D world.

COMPONENTS USED IN
AUGMENTED REALITY
Head mounted display.
Tracking system.
Mobile computing power(High
speed portable computers).

HEAD-MOUNTED DISPLAY
• Head mounted display will
enable us to view graphics and
text created by Augmented
reality systems.
 A typical HMD has either one or
two small displays with lenses
and semi-transparent mirrors
embedded in a helmet, eye-
glasses (also known as data
glasses) or visor. The display
units are miniaturized and may
include CRT, LED or OLED.
Head mounted display

7.
TRACKING SYSTEM
 It is used in order to track
user’s location with
respect to the
surrounding. For this two
tracking system is used :
Global Positioning
System(GPS).
Hi-Ball Tracking
System
The Hi ball Tracking
System uses an optical
sensing device
and LED-embedded ceiling
tiles to track movements
over a short range.

8.
MOBILE COMPUTING
POWER
For augmented reality systems to work mobile
computers are a good option.
Mobile computing can be accomplished with
help of wearable computers , which is the
battery powered computer system worn on the
user’s body.
It is designed for mobile & predominantly hand
free operations often incorporating head
mounted display & speech input.

APPLICATIONS
MAINTANENCE AND CONSTRUCTION:
Markers can be attached to a particular object that a
person is working on, and the augmented-reality system
can draw graphics on top of it, the system only has to
know where the user is in reference to the object that he
or she is looking at.
MILITARY:
Augmented reality displays could
also highlight troop movements,
and provide hidden place for them in
the nearby surrounding.

10.
APPLICATIONS
The primitive versions of augmented
reality are already here on some cell
phones, particularly in applications for
the iPhone and phones with the
Android operating system. Cell phone
owners can download an application
called Layar.
LAYAR uses camera and GPS to gather
information about the surrounding
area.
Layar then shows information about
restaurants or other sites in the area,
overlaying this information on the
phone's screen. You can even point the
phone at a building, and Layar will tell
you if any companies in that building
are hiring, or it might be able to find
photos of the building on Flickr or to
locate its history on Wikipedia.
An phone user displays the augmented
reality app Monocle, which combines the
phone’s camera view with tiny tags
indicating the names, distances and
user ratings of nearby bars, restaurants
and more.
IN CELL PHONES

APPLICATIONS
 VIDEO GAMES
Because of augmented
reality development video
game is like
projecting in the real world
giving a real experience of
gaming.
For example-Total immersion
company designs a software
that uses augmented reality
in base ball cards to display
the related video on screen .
When user move these cards
in field of view of camera ,the
3D figure will perform the
concerned actions.
Augmented reality can breathe
a little life into your sports
trading cards.

12.
LIMITATIONS
 Tracking and orientation might not be
accurate.
For wearable augmented reality system,
there are still enough computing power to
create stereo 3D graphics.
The size of Augmented Reality(AR) systems
is yet another problem . It is very large,
researchers are working to make it smaller.

13.
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.

14.
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
