RISE OF AUGMENTED REALITY:
Current and Future Applications

2.
Topics to be discussed :
 Introduction
 Implementation
 Components
 Applications & Limitations
 Conclusion & Future Scope
 References

3.
Introduction:
 Augmented Reality is a field of computer
research which deals with combination of
reality with computer generated data.
 It is still in an early stage of research and
development, possibly by the end of this
decade, we will see the first mass-
marketed augmented-reality system.

4.
Augmented Reality System :
 An augmented reality system is one that
Combines real and virtual world that is
interactive in real time that will be registered
in 3D.

5.
Augmented Reality :
 Augmented reality will truly change
the way we view the world.
 Picture yourself walking or driving
down the street with informative
graphics appearing in your field of
view, and audio will coincide with
whatever you see.
 These enhancements will be refreshed
continually to reflect the movements
of your head.

6.
Implementation / Architecture :
To implement there are four things that we require to do
 First, find users location
 Second find users orientation (view)
 Third generating information
 Fourth augmenting it to users view
Find user’s location
Find user’s orientation (view)
Generate data
Augment generated
data to user’s view

7.
Components Required :
Here are the three components needed to make
an augmented-reality system work:
 Display
 Tracking system
 Mobile computing power

8.
1)Head-mounted Displays
 Just as monitors allow us to see text and
graphics generated by computers, head-
mounted displays (HMDs) will enable us
to view graphics and text created by
augmented-reality systems.
 There are two basic types of HMDS:
 A).video see-through
 B).optical see-through

9.
A. Video See Through Displays
 They block out the wearer's surrounding environment, using
small video cameras attached to the outside of the goggles to
capture images.
 On the inside of the display, the video image is played in real-
time and the graphics are superimposed on the video.

10.
B. Optical See Through Display
 Optical see through is not fully realized yet. It is supposed to
consist of ordinary looking pair of glasses that will have light
source on the side to project images onto the retina.

11.
2)Tracking and Orientation
 The biggest challenge facing developers of augmented reality is the need to
know where the user is located in reference to his or her surroundings.
 There's also the additional problem of tracking the movement of users' eyes
and heads.
 Types :
A.GPS
B.Real time differential GPS

12.
A. GPS – Tracking Technology
 Currently, the best tracking technology
available for large open areas is the
Global Positioning System.
 However, GPS receivers have an accuracy
of about 10 to 30 meters, which is not bad
in the grand scheme of things, but isn't
good enough for augmented reality, which
needs accuracy measured in millimeters
or smaller.

13.
B. Real Time Differential GPS
 There are ways to increase tracking
accuracy.
 For instance, the military uses
multiple GPS signals.
 There is also differential GPS, which
involves using an area that has
already been surveyed.

14.
APPLICATIONS :
 Once researchers overcome the challenges that face them,
augmented reality will likely pervade every corner of our lives. It
has the potential to be used in almost every industry, including:
 Medical
 Entertainment
 Military Training
 Engineering Design
 Robotics and Telerobotics
 Education

17.
Current challenges :
 Accurate tracking and orientation
 For wearable augmented reality system, there are
still not enough computing power to create stereo
3D graphics
 The size of AR systems is yet another problem

18.
Conclusion & Future scope :
 Tourists and students could use these systems to
learn more about a certain historical event.
 The ultimate goal of augmented system is to create a
system such that a user CANNOT tell the difference
between the real world and the virtual augmentation
of it.
 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.
