Augmented reality (AR) enhances the real world by overlaying digital content and information. AR uses displays like head-mounted displays, combines virtual and real imagery in real-time by tracking the user's position, and requires mobile computing power. Current uses include navigation apps and medical/military overlays, while future applications could involve more immersive education and gaming. As the technology advances, AR will continue to blur the line between physical and digital worlds.

2. WHAT IS AUGMENTED REALITY ?
❑Augmented reality (AR) is a field of
computer research which deals with the
combination of real-world and computer-
generated data.

3. Augmented Reality vs Virtual reality
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
Virtual Reality
⮚Totally immersive
environment
⮚Senses are under control
of system
⮚Need a mechanism to
feed virtual world to user

4. HOW DOES AR WORK
❑The basic idea of augmented reality is to
superimpose graphics, audio and other sense
enhancements over a real-world environment in
real-time.
❑The graphics will then change to accommodate
the user’s eye or head movements.

5. WHAT IS NEEDED ?
❑There are three components needed in order to
make an augmented-reality system work:
❑Display
❑Tracking system
❑Mobile computing power

6. DISPLAY
❑ Head Mounted Display

7. DISPLAY
❑ Handheld Display

8. DISPLAY
❑ Projective Display

9. TRACKING SYSTEM
❑ Global Positioning System
⮚ Currently, the best tracking
technology available for large
open area is GPS

10. MOBILE COMPUTING POWER
❑ Portable Computing Devices Like : -
⮚ Smartphones
⮚ Laptop
⮚ Tablets

11. CURRENT USES OF AR
❑ HUD (Head Up Display):
❑ Used in commercial
aircraft, automobiles,
and other applications
❑ Presents data without
requiring the user to
look away from his or
her usual viewpoint

12. CURRENT USES OF AR
Wikitude – AR Travel Guide
❑ Mobile travel guide for the Android platform (open
source OS for cell phones).
❑ Plan a trip or find about current surroundings in real-
time.

13. FUTURE OF AR
❑ Military:
❑ The Office of Naval Research has sponsored AR
research
❑ AR system could provide troops with vital
information about their surroundings.

14. FUTURE OF AR
❑ Medical:
❑ Superimpose an
image from an MRI
onto a patient’s body.
❑ This might allow
surgeons to pinpoint a
tumor to remove.

15. FUTURE OF AR
❑ Education:
❑ Used in labs where students can learn more about
the experiments they are participating in.

16. FUTURE OF AR
❑ Gaming:
❑ Games like Pokemon go is based on Augmented Reality.
❑ This game allows the user to run around in the real world while
playing a game in the computer generated world.

17. FUTURE OF AR
Google’s Project Glass
❑ Natural language voice
commands
❑ Google’s Android Operating
System
❑ Provide 3G or 4G wireless
connection
❑ Mounting the device onto
prescription glasses

18. CONCLUSION
Augmented reality will further blur the line between
what's real and what's computer generated by
enhancing what we see, hear, feel.
