3. AUGMENTED REALITY
 Augmented Reality is a field
of Electronics 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 time.
Augmented-reality displays will
overlay computer-generated
graphics onto the real world.

4. 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.

5. HISTORY
 1966: Ivan Sutherland invents the head-mounted display and
positions it as a window into a virtual world.
 1994: Julie Martin creates first ‘Augmented Reality Theater
production’.
 2013: Google announces an open beta test of its Google Glass
augmented reality glasses.
The glasses reach the Internet through
Bluetooth, which connects to the
wireless service on a user’s cellphone.
The glasses respond when a user speaks,
touches the frame or moves the head.

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

7. 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.

8. 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

9. 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.

11. APPLICATIONS
 EDUCATION: Augmented reality applications can
complement a standard curriculum. Text, graphics, video and
audio can be superimposed into a
student’s real time environment.
MILITARY:
Augmented reality displays could
also highlight troop movements,
and provide hidden place for them
in the nearby surrounding.

12. APPLICATIONS
Sports and Entertainment
AR has become common in sports telecasting. Sports and
entertainment venues are provided with see-through and overlay
augmentation through tracked camera.
Medical
Augmented Reality can provide the
surgeon with information, which are
otherwise hidden, such as showing the
heartbeat rate, the blood pressure, the
state of the patient’s organ, etc. as an
X-ray with another such as video.

13. ADVANTAGES
• It is UNIQUE
• Have vast majority Content .
• Interactivity maintains a viral loop .
• Personalization
13

14. DISADVANTAGES
• Physical danger
• Privacy control
• Difficult to IMPLEMENT
14

15. 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.

16. 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.
