Augmented Reality is a developing area in the field of virtual reality research. Similarly like Virtual Reality, Augmented Reality is becoming an emerging platform for numerous applications. The work done here reveals the current state-of-the-art in Augmented Reality. Moreover current issues, trends and challenges are analyzed here.

3. Introduction :
 Augmented Reality is a
field of computer
research which deals with
combination of reality
with computer generated
data.
 The basic idea of
augmented reality is to
super impose graphics,
audio and other sense
enhancements over a
real-world environment
in real-time.

4. TYPE 1:-Augmented Reality (AR1), whereby
the artificial imagery is layered over the
background POV IN REAL-TIME
TYPE 2:- Augmented Reality (AR2), whereby
the artificial imagery is layered over the
background FROM AN IMPERSONAL POV OR NOT
IN REAL-TIME
Types:

5. Virtual vs Augmented Reality
 Virtual reality creates immersive,
computer generated
environments which replaces
real world.
 Virtual reality serves for at totally
immersive environment . The
senses are under control of the
system.
 The user is completely immersed
is an artificial world and cut off
from real world.
 Augmented reality is closer to the
real world. augmented reality
add graphics, sounds & smell to
the natural world, as it exists.
 That is ,the user can interact with
the real world, and at the same
time can see, both the real and
virtual world co-existing.
 User is not cut off from the
reality

6. Implementation of
AR Travel Guide:
Mobile travel guide for
the Android platform
(open source OS for cell
phones).
Plan a trip or find about
current surroundings in
real-time.

7. Find user’s location
Find user’s orientation (view)
Generate data
Augment generated
data to user’s view
To implement there are four things that we
require to do find user’s location find user’s
orientation (view)generating information
augmenting it to user’s view
Implementation

8. A)MILITARY B)MEDICAL
C)GOOGLE’S GLASS D)MOBILE APP
APPLICATIONS

9. 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.

10. Conclusion :
 Endless opportunities in augmented mobile
apps.
 Basic problems of daily life can be solve.
 Time saving
