This document discusses augmented reality systems and their components. It describes how augmented reality overlays computer-generated data onto the real world in real-time by using displays like head-mounted displays. Examples of augmented reality applications include Wikitude and Google Glass. The key components of an augmented reality system are a display, tracking system, and mobile computing power. The document also covers the differences between augmented and virtual reality, potential applications, and current limitations.

3. Introduction
Augmented Reality is a field of
computer research which deals
with combination of reality with
computer generated data.
With augmented-reality displays,
which will eventually look much
like a normal pair of glasses,
informative graphics will appear 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.

4. Augmented Reality System
An augmented reality system is one that
Combine real n virtual world
Is interactive in real time
Is registered in 3D.

5. Mobile application based on
Augmented Reality …
Wikitude - WIKITUDE World Browser
presents the user with data about their
surroundings, nearby landmarks, and
other points of interest by overlaying
information on the real-time camera
view of a smart-phone.
Augmentedev- It is basically
superimposes the 3D graphics on
real world by placing a marker in
front of smart device’s camera.

6. Components
Here are the some components needed to make an augmented-reality
system work:
display
tracking system eg- Gps,Digital compass
mobile computing power

7. 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:
 video see-through
optical see-through

8. 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. One problem with the use of
video cameras is that there is more lag, meaning that there is a delay in
image-adjustment when the viewer moves his or her head.

9. Optical See Through Display
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. Eg- Google glass

10. Augmented VS Virtual Reality
 Virtual reality creates
immersive, computer generated
environments which replaces
real world.
 Augmented reality is closer to
the real world. augmented
reality add graphics, sounds &
smell to the natural world, as it
exists.

11. Applications fields of AR
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:
Education
Military
Instant information
Gaming

12. Limitations
Accurate tracking and orientation
For wearable augmented reality system, there are still
enough computing power to create stereo 3D
graphics
The size of AR systems is yet another problem.

13. 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.
