Augmented reality combines computer generated data with reality. It is still in an early research stage but may become mainstream by the end of the decade. AR systems combine real and virtual worlds in real-time and are registered in 3D. Examples of AR uses include education by allowing students to see virtual objects, instant information for tourists through historical recreations, and gaming by projecting video games into the real world. The future may include expanding computer screens into real spaces using eye or gesture controls.

2. Augmented Reality
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

3. An augmented reality system is one that :
•Combine real n virtual world
•Is interactive in real time
•Is registered in 3D.

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.

7. AR System needs to know two
things
1.Where the user is
located
2. Where he is
looking

8. Using Augmented Reality
Education
In an Augmented Reality interface
students can be seated around a table
and see each other at the same time as
a virtual heart floating in their midst.
This results in conversational behavior
that is more similar to natural face-to-
face collaboration than to screen
based collaboration [Kiyokawa 2002].

9. Using Augmented Reality
Instant information -Tourists and students could
use these systems to learn more about a certain
historical event.
Imagine walking onto a Civil War battlefield and
seeing a re-creation of historical events on a head-
mounted, augmented-reality display. It would
immerse you in the event, and the view would be
panoramic.

10. Using Augmented Reality
Gaming - How cool would it be to take video games
outside? The game could be projected onto the real
world around you, and you could, literally, be in it as one
of the characters. One Australian researcher has created
a prototype game that combines Quake, a popular video
game, with augmented reality. He put a model of a
university campus into the game's software. Now, when
he uses this system, the game surrounds him as he walks
across campus.

11. Looking into future ……
Expanding a PC screen to real environment..program
windows & icons appear as virtual devices in real
space & are eye or gesture operated, by gazing or
pointing.

12. Looking into future ….
Replacement of cell phones: eye dialing.
Examples might be a virtual wall clock, a to-do list for
the day clocked by your bed for you to look at first
thing in the morning, etc.

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.
