Augmented reality (AR) combines the real world with virtual elements. AR works by tracking a user's position, computing virtual objects, and displaying them overlaid on the real world through a head-mounted display. The key components of AR are head-mounted displays, tracking systems, and mobile computing power. AR has applications in medicine for surgical planning, education for enhancing lessons, the military for enhancing situational awareness, games for blending virtual and real worlds, and maintenance/construction for overlaying instructions. While tracking and size limitations currently exist, AR has huge potential to blur real and virtual experiences.

3. What is Augmented Reality
•Augmented Reality = Real World + Virtual Layer
•A combination of real scene viewed by a user and a virtual scene
generated by a computer that augments the scene with additional
information.

4. How AR works?
Augmented Reality 4
• Tracking Position
• Computing
• Display 2D/3D objects

5. Components of AR
• Head Mounted Display
• Tracking System
• Mobile Computing Power (High Speed Portable Computer)
Augmented Reality 5

6. Head Mounted System
• HMD will enable use to
view graphics and text
created by augmented
reality system.
• HMD is used in military,
fire, police, and civilian.

7. Tracking System
• Tracking system in
AR is to know user
location in references
to his surrounding.
• For this two TS is use
• Global Positioning
System
• Hi-Ball TS

8. Mobile Computing Power
• Mobile Computing
can be accomplished
with the help of
wearable computer.
• A wearable computer
is a battery powered
computer system
worn on the user’s
body(Belt, Backpack,
etc.).

9. Applications of AR
•Medical
•Education
•Military
•Game
•Maintenance & Construction
Augmented Reality 9

10. Medical
• Medical AR
application will allow
for more advance
pre-operative
imaging studies,
surgeons examine.
• AR system can use
streaming input data
to create virtual
superimposed images
in real time.
Augmented Reality 10

11. Education
• AR application can
complement a
standard curriculum.
• Text, Graphic, Video
and Audio can be
superimposed into a
student’s real time
environment.
Augmented Reality 11

12. Military
• AR displays could
also highlight troop
movements and
provide hidden place
for them in the
nearby surrounding.
Augmented Reality 12

13. Game
• Because of AR
development of video
game is like
projecting in the real
world giving a real
experience of game.
Augmented Reality 13

14. Maintenance & Construction
• Markers can be
attached to a
particular object that
a person is working
on, and the AR
system can draw
graphic on top of it.
• The system has to
know where the user
is in reference to the
object that he/she is
looking at
Augmented Reality 14

15. Limitation
• Tracking and orientation might not be accurate.
• The size of AR system is yet another problem. It is very large,
researchers are working to make it smaller.
• AR is also still simple computer technology, lacking the human
touch of a knowledgeable friend or tour guide.
Augmented Reality 15

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 application in almost every field.
• The goal is to make a system that will be so efficient that the user
will not be able to tell the difference between the real word and the
virtual augmentation.
