Augmented reality is a live, copy, view of a physical, real-world environment whose elements are augmented by computer-generated sensory input such as sound, video, graphics or GPS data.

REALITY

3. WHAT IS AUGMENTED REALITY?
 Augmented reality (AR) is a live, direct or indirect, view of a physical, real-
world environment whose elements are augmented by computer generated sensory input such as sound, video, graphics or GPS data.
 It is related to a more general concept called mediated reality, in which a
view of reality is modified by a computer.
 The technology functions by enhancing one’s current perception of
reality. Virtual reality replaces the real world with a simulated one.
Augmentation is conventionally a semantic context with environmental
elements, such as sports scores on TV during a match. With the help of
advanced AR technology) the information about the surrounding real world
of the user becomes interactive and digitally manipulable.

4. DIFFERENCE BETWEEN AUGMENTED
REALITY AND VIRTUAL REALITY?
 The difference between augmented reality and virtual reality is the level of
immersion. Virtual reality is based upon a complete simulation of a real
world environment which the user can explore and interact with by means of
a head mounted display (HMD) and input device, e.g. data glove.

5. DIFFERENCE BETWEEN AUGMENTED
REALITY AND VIRTUAL REALITY?
 The user loses or immerses themselves in this environment. But with
augmented reality the user sees the real world but with the addition of
computer generated images which are overlaid on various objects within the
real world. They are still aware that they are in the real world as compared to
the full immersion in a virtual world.
 They use a device such as a smartphone or a wearable device - complete with
a webcam which contains software that recognises an image and helps
displays this onto an object.

6. HOW AUGMENTED REALITY IS TAKING
OVER VIRTUAL REALITY?
 Virtual reality replaces the real with the artificial whereas augmented reality
enhances real life with artificial images. Augmented reality is available in
particular smartphones such as the iPhone and Android.
 These phones have GPRS which obtains information about a particular
geographical location which can be overlaid with tags etc. Images, videos etc
can be imposed onto this location.

7. HOW AUGMENTED REALITY IS TAKING
OVER VIRTUAL REALITY?
 Handheld devices such as smartphones and the iPad are other ways to use
augmented reality. They contain software, sensors, a compass and small
digital projectors which display images onto real world objects.
 An important issue is that of successfully integrating computer generated
images within the real world is that they need to be realistic and useful to be
of real benefit to the user and thus Augmented reality is taking over virtual
reality.

8. APPLICATIONS OF AUGMENTED
REALITY
EDUCATION
 Augmented reality applications can complement a standard
curriculum. Text, graphics, video and audio can be superimposed into
a student’s real time environment. Textbooks, flashcards and other
educational reading material can contain embedded “markers” that,
when scanned by an AR device, produce supplementary information
to the student rendered in a multimedia format.

9. APPLICATIONS OF AUGMENTED
REALITY
INDUSTRIAL DESIGN
 AR can help industrial designers
experience a product's design and
operation before completion.
Volkswagen uses AR for comparing
calculated and actual crash test
imagery. AR can be used to visualize
and modify a car body structure and
engine layout.

10. APPLICATIONS OF AUGMENTED
REALITY
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. AR can be used to let a doctor
look inside a patient by combining one
source of images such as an X-ray with
another such as video.

11. APPLICATIONS OF AUGMENTED
REALITY
NAVIGATION
 AR can augment the effectiveness of
navigation devices. Information can be
displayed on an automobile's windshield
indicating destination directions and meter,
weather, terrain, road conditions and traffic
information as well as alerts to potential
hazards in their path.

12. AUGMENTED REALITY IN
CELLPHONES.
A user displays the augmented reality app Yelp’s Monocle, which
combines the phone’s camera view with tiny tags indicating the names,
distances and user ratings of nearby bars, restaurants and more.

13. AUGMENTED REALITY IN
CELLPHONES.
 While it may be some time before you buy a device like SixthSense, more
primitive versions of augmented reality are already here as applications for
the iPhone and phones with Android OS.

In the Netherlands, cell phone owners can download an application called
Layar that uses the phone's camera & GPS capabilities to gather information
about the surrounding area. It then shows information about restaurants or
other sites in the area, their ratings and reviews.
 There are other augmented reality apps out there for the iPhone and many
more in development. Urbanspoon has much of the same functionality as
Yelp's Monocle. Then there's Wikitude, which finds information
from Wikipedia about sites in the area.

14. HOW AUGMENTED REALITY ACTUALLY
WORKS?
 The webcam connected to your computer is capturing video in the traditional
manner . When you hold the “marker” in front of the webcam it sees the
marker, captures the information / pattern encoded in it and sends this
information to the computer.
 The computer recognises the information and overlays the marker with an
image. To the viewer it appears as though the image has materialised by
magic. The computer can track the size and movement of the image. This
means if you move the marker closer to the webcam the image will get
bigger. If you tilt the marker to the left, the image will tilt to the left.
 This process is similar to sports telecasts seen on television, such as
swimming events, where a line is dynamically added across the lanes to
indicate the virtual position of the current record holder as a race proceeds.

15. FUTURE OF AUGMENTED REALITY
 People may not want to rely on their cell phones, which have small
screens on which to superimpose information. For that reason,
wearable devices like Sixth Sense or augmented-reality
capable contact lenses and glasses will provide users with more
convenient, expansive views of the world around them. Screen real
estate will no longer be an issue.
 You may be able to play a real-time strategy game on your computer,
or you can invite a friend over, put on your AR glasses or AR lenses,
and play on the table top in front of you. The future of augmented
reality is clearly bright, even as it already has found its way into our
cell phones and video game systems. Real time data will be streamed
to us about everything we see, smell, hear and touch. We will be able
to interact with this data in order to make more informed decisions.

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 and smell.
