Augmented reality is a virtual scene generated by a computer that augments the scene with additional information. This presentation explains the use of augmented reality in today's world.

5. WHAT IS AUGMENTED
REALITY??
• a real scene viewed by a user and
• a virtual scene generated by a computer
that augments the scene with additional
information
• interactive in 3D
• Interactive in real-time

6. • Combines real and virtual
world aspects
e.g., Real desk with virtual lamp and two virtual chairs
(ECRC)

7. HOW AUGMENTED REALITY IS DIFFERENT
FROM VIRTUAL REALITY
AUGMENTED REALITY VIRTUAL 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
• Hard to register real and
virtual
• Totally immersive
environment
• Senses are under control
of system
• Need a mechanism to
feed virtual world to user
• Hard to make VR world
interesting

9. Milgram’s Reality-Virtuality Continuum
• Virtual and real environments are at opposite ends of the reality
continuum
• Augmented reality is closer to the real environment
• Basically, AR is the real world with benefits

10. CHARACTERSTICS
 Besides adding objects to a real environment, AR
also has the potential to remove them.
 Blending the real and virtual poses problems with
focus and contrast and some applications require
portable AR systems to be truly effective.
 AR might apply to all senses, not just sight

11.  AR could be extended to include sound.
 Another example is haptics.
 Gloves with devices that provide tactile feedback might augment
real forces in the environment. For example, a user might run his
hand over the surface of a real desk which can augment the feel
of the desk, perhaps making it feel rough in certain spots.

12. AR DISPLAYS

13. • Combines and displays physical world images
and virtual graphical objects
HEAD ATTACHED DISPLAYS
• Some displays can automatically switch between 2D
and 3D representations.
• Head-up displays are currently used in fighter jets
that include full interactivity, including eye pointing.

14. Handheld Displays
• Small handheld computing device
• Uses global positioning systems (GPS))
• Smartphones with phone
apps are the most
commonly used handheld
devices.
• Cell phones now have cameras
and screens allowing the
combination of real world data
to intertwine with virtual
data.

15. Spatial Displays
• Nothing to wear and/or carry
• Uses digital projectors to display
information
• Marker-based and markerless
devices
• The AR Hand Phone allows the
user to call a friend using an AR
keypad without removing their
cell phone from their pocket or
purse.
• The AR Keyboard takes the place of
a physical computer keyboard

17. Advertising Applications
Promote products via interactive AR
applications
Movie character
speaks to you when
you pass her
outdoor movie
poster
City sites tour

18. Marketing Applications
• Assist consumers on location with ratings, reviews, and
other information
• Marketing Applications assist consumers on location when shopping
and dining by providing ratings, reviews, menus, and other types
of information.

19. ART APPLICATIONS
• Create art over real art
• Simulate construction projects
• Create virtual objects on locations
The water pouring out of the windows of this
high-rise building. This is typical special effects
for movies.

20. EDUCATIONAL APPLICATION
• Generate models in
different settings
• Create 3D
graphics of
curriculum
content
• Architect students could use
them to show scale models of
buildings cutting time down for
construction and presentation
proposal.

21. • Have books come alive
• Provide powerful
contextual,
explorative, and
discovery learning
experiences
• Facilitate
collaboration
among
distributed team
members
• AR books can be used to enhance
learning by showing globes that
pop out of the page, but the books
are printed normally

22. OTHER APPLICATIONS
 Astronomy
 Architecture
• Google’s Sky Map
• P Universe
 Computer Science
• AR Sights
Sky map

23. FUTURE OF AR
 Expanding a PC screen into the real world
 “Holodecks”
 Replacement of cell phone and vehicle
 navigation screens

24.  AR-enabled contact lenses
 Virtual retinal displays
 Virtual everything Virtual gadgetry
Subscriptions to group-specific AR feeds

25. • Used in labs where students can learn more about
the experiments they are participating in.
Military:
• The Office of Naval Research has sponsored AR
research
• AR system could provide troops with vital
information about their surroundings
Medical:
• Superimpose an image from an MRI onto a
patient’s body.
• This might allow surgeons to pinpoint a tumor to
remove.
Education:
