2. AUGMENTED REALITY
• Augmented Reality is a technology that
superimpose a user’s real world view with(computer
generated) virtual text or image on the screen in real
time.
• For an AR user the real and virtual object coexist on the
same view
• The idea of AR is related to the concept of virtual
reality .

4. Short History of AR and VR
• In 1901, author L.Frank Baum first mention
the idea of character marker which is an
electronic display overlaying on real life
• In 1989, Jaron anier coins the phrase ‘Virtual
reality’ and its concept model
• In 1990, Thomas P.Caudell creates the concept
and phrase of Augmented Reality

5. • The concept of Augmented Reality is old, but
only recently it became fully implementable
and reliable .
• Let see why
1. Higher resolution camera on smart
devices enable accurate image and object
identification.
2.Enhanced Processing capability of CPU
and GPU on smart devices enable accurate
image and object identification and feature
extraction.

6. 3.Large memory and fast input and/output
memory access enables large amounts of AR
object information to be stored and quickly
retrieved.
4.High Definition displays on smart devices
enable sharpe virtual text and images to be
super imposed in an elegant and easy on the
eye fashion
5. Broadband wireless and wired networking
enables AR servers/database information to
be quickly retrieved.

7. AR Characteristics
• AR is mixture of real life and virtual reality
• AR user are able to obtain useful information
about location or object, and can interact with
virtual contents in the real world.
• AR users commonly feel less separated from
the real world
• Fantasies & illusions can be created and
superimposed on a real world view.

8. MOBILE AUGMENTED REALITY
SYSTEM (MARS)
• Augmented reality (AR), in which 3D displays
are used to overlay a synthesized world on top
of the real world, and mobile computing, in
which increasingly small and inexpensive
computing devices, linked by wireless
networks, allow us to use computing facilities
while roaming the real world.

9. AR Classification
1. Sensor based AR
GPS The Global Positioning System gives you
accurate position and velocity information
anywhere in the world.
Accelerometer Accelerometers in mobile
phones are used to detect the orientation of
the phone.

10. AR Classification
GyroSensor
• The gyroscope, or gyro for short, adds
an additional dimension to the information
supplied by the accelerometer by tracking
rotation or twist.
Example : Layar, WikiTude, Sekai Cam

11. AR Classification
2. Vision Based AR
Computer Vision
Sensors to track the position and
orientation of the user field of view (FOV)
Computer vision to detect objects in
the user FOV.
OpelGL
Open Graphics Library is a cross platform API
for rendering 2D and 3D vector graphics.
Example : Vuforia, Metaio.

12. AR Classification
3.Hybrid tracking based AR
It is combination of sensor based and vision
based.
Example : Outdoor AR

13. Effective Development
Methodologies for AR application
• There are two development methodologies for
augmented reality applications:
1.Marker Based
2.Marker Less

14. Marker-Based:
• Marker-based augmented reality (also called
Image Recognition) uses a camera and some
type of visual marker, such as a QR/2D code,
to produce a result only when the marker is
sensed by a reader.
• Marker based applications use a camera on the
device to distinguish a marker from any other
real world object. Distinct, but simple patterns
(such as a QR code) are used as the markers.

16. Marker-less
• This method uses an advanced tracking system
that allows active tracking and recognition of
real environment on any type without using
discrete markers (also called location-based,
position-based, or GPS) .
• It is most commonly used for mapping
directions, finding nearby businesses, and
other location-centric mobile applications.

18. Projection Based Augmented
Reality
• Projection based augmented reality works by
projecting artificial light onto real world
surfaces.
• Projection based AR applications allow for
human interaction by sending light onto a real
world surface and then sensing the human
interaction (i.e. touch) of that projected light.

20. Superimposition Based Augmented
Reality
• Superimposition based augmented reality
either partially or fully replaces the original
view of an object with a newly augmented
view of that same object.
• A strong consumer-facing example of
superimposition based augmented reality
could be found in the AR Furniture Catalogue

22. AUGMENTED REALITY
APPLICATIONS

23. Military AR Uses
• Augmented reality when it comes to military
applications of the technology a transparent display
is positioned directly in the fighter pilot's view.
• Data typically displayed to the pilot includes altitude,
airspeed and the horizon line in addition to other
critical data. pilot doesn't have to look down at the
aircraft's instrumentation to get the data he needs.

24. The Head-Mounted Display (HMD) is used by
ground troops. Critical data such as enemy
location can be presented to the soldier within
their line of sight. This technology is also used
for simulations for training purposes.

25. Medical AR Uses
• Medical students use AR technology to practice
surgery in a controlled environment. Augmented
reality can reduce the risk of an operation by giving
the surgeon improved sensory perception
• Neurosurgery is at the forefront when it comes to
surgical applications of augmented reality. The ability
to image the brain in 3D on top of the patient's
actual anatomy is powerful for the surgeon.

27. AR Apps for Navigation
• Navigation applications are possibly the most
natural fit of augmented reality with our
everyday lives.
• Enhanced GPS systems use augmented reality
to make it easier to get from point A to point
B. Using the Smartphone's camera in
combination with the GPS, users see the
selected route over the live view of what is in
front of the car.

29. Sightseeing in Augmented Reality
• The ability to augment a live view of displays in a
museum with facts and figures is a natural use of the
technology.
• Out in the real world, sightseeing has been enhanced
using augmented reality. Using a smartphone equipped
with a camera, tourists can walk through historic sites
and see facts and figures presented as an overlay on their
live screen. These applications use GPS and image
recognition technology to look up data from an online
database. In addition to information about a historic site,
applications exist that look back in history and show how
the location looked 10, 50 or even 100 years ago.

31. Maintenance and Repair
• Using a head-worn display, a mechanic making
repairs to an engine can see superimposed imagery
and information in his actual line of sight. The
procedure might be presented in a box in the corner,
and an image of the necessary tool can illustrate the
exact motion the mechanic needs to perform.
• The augmented reality system can label all the
important parts. Complex procedural repairs can be
broken down into a series of simple steps.

33. Games
• There are lots of AR games and AR toys that can
merge the physical and virtual world.
• One well-known example is Snapchat, which lets you
use your smartphone to overlay fun masks and
designs on your face before sending a message. The
app uses a live version of your face to put a virtual
image on top of it.
• Other examples of augmented reality games
include Pokemon GO!, INKHUNTER, Sharks in the
Park (Android and iOS), SketchAR, Temple Treasure
Hunt Game, and Quiver. See these AR iPhone
games for more.

34. Advertising and Promotion
• It uses the camera on your mobile device to
augment your reality. Using the GPS location
feature in your mobile device, the Layar application
retrieves data based on where you are and displays
this data to you on your mobile screen. Details about
popular places, structures and movies are covered by
Layar. Street views show the names of the
restaurants and businesses superimposed over their
storefronts.

36. Education
• One example of a free AR app is SkyView, which lets
you point your phone to the sky or ground and see
where stars, satellites, planets, and constellations are
located at that exact moment, both during the day
and at night.

37. • Sky View is considered a layered augmented
reality app that uses GPS because it shows you
the real world around you.
• Google Translate is another example of an AR
app useful for learning. With it, you can scan
text that you don’t understand and it will
translate it for you in real time.
