3. What is Virtual Reality (VR) ?
• Virtual Reality is a computer generated, multi-sensory information
program which tracks a user in real time i.e. computer system is
used to create an artificial world in which the user has the
impression of being in that world ,with the ability to navigate
through and manipulate objects in that world.

4. Virtual Reality Concepts
• The concepts behind virtual reality are based upon theories about :
• A long held human desire to escape the boundaries of the ‘real world’ by
embracing cyberspace.
• Once there we can interact with this virtual environment in a more
naturalistic manner which will generate new forms of human-machine
interaction (HMI).

5. Augmented (AR) &
Mixed Reality (MR)

6. Augmented Reality (AR)
• Refers to a system in which the user views and acts within an
enhanced version of the real world. The enhancements are virtual
(computer- generated), and can include objects or information.

7. Mixed Reality (MR)
• sometimes referred to as hybrid reality
• encompassing both augmented reality and augmented virtuality
• refers to the merging of real and virtual worlds to produce new
environments and visualisations where physical and digital objects
co-exist and interact in real time

10. AR/MR Application Areas…
• Maintenance
• Training
• Tourism/ Cultural Heritage
• Design / Construction
• Battlefield Information Display

12. Used in Sports

13. AR IN GAMES

14. TYPES OF AR
Marker-based AR
Markerless AR
GPS & Compass
Technology

15. MARKER BASED
 Marker-based AR uses a camera and a visual marker to
determine the center, orientation, and range of its spherical
coordinate system.
 Most of the time, the applications using markers are based on
open source technology.
 ARToolkit is the first fully-featured toolkit for marker-based AR
 It has the advantage to be easily affordable but sometimes it
is not supported and fairly weak
 Total Immersion provides the world’s most widely used
commercial augmented reality platform.
TYPES OF AUGMENTED REALITY

16. MARKER LESS TRACKING
 This is currently one of the best technology for
tracking
 It performs active tracking and recognition of real
environment on any type of support without using
special placed markers.
 Allows more complex applications of Augmented
Reality.

17. GPS and Compass
Technology :
 Found in smartphones and tablets
 Uses devices' GPS, compass features
and high-speed wireless networks
Allows more complex applications of
Augmented Reality.
Main
Attraction: Limitation:
 Provides useful local web-content
information and added services in 2D
format at the geo-location of the user
 Fairly imprecise due to current
inaccuracy of the GPS technology

18. Used in Aircraft

19. Used in Movies

21. Medical Applications
• A research team used Augmented Reality to
cope with a 25-year-old woman’s cockroach
phobia. Virtual cockroaches were displayed
on the woman’s hands. After some sessions,
her phobia for cockroaches has been
eliminated.

22. Characteristics of AR
It combines real and virtual
World
It is interactive in real time
It is registered in 3D.

23. Hardware needed for AR….
 Display
 Tracking (GPS, compass)
 Input devices (Camera)
 sensors (accelerometer)
 processer (CPU, any operating system or software)

24. GOOGLE GLASS
 Google Glass is a wearable
computer with an optical head
mounted display (OHMD). It was
developed by Google.
 Using Augmented Reality
Technology.

26. EARTHMINE
 Company uses vehicle
mounted camera.
 Capture imagery and three
dimensional data.
 Get information from GPS
 intelligent software.

29. Advantages of AR
AR Improve interaction
Advances in technology
Military Trainings which could be less expensive
Rapid augmentation in tourism.
Effective in Medical Field.
Easy to locate desired places.
A Good way of teaching.
Increased the learning abilities.

30. Disadvantages of AR
o Three dimensional, real-time running augmented reality programs like
"first person shooters" have been believed to increase teen aggression
because they normalize violence.
o The lack of privacy.
o Difficult to maintain Augmented Reality Systems.
o Augmented reality is leading to an era of no privacy, where criminals
could simply point their phone at victims and learn anything they need
to know about them.

31. • Google Glasses and
Augmented ID or any
other face detection
application effect the
privacy of humans.

32. CONCLUSION
• Augmented reality (AR) is a way of delivering entertainment media that uses
computer generated graphics transposed over real-life scenes.
• Create a system such that User CANNOT tell the difference between the real
world and the virtual augmentation of it.
• To add information and meaning to a real object or place.
• Use of Medical Application increased and save the life of humans.
• But developers should controls the privacy. People thinks Augmented reality
is leading to an era of no privacy, where criminals could simply point their
phone at victims and learn anything they need to know about them.
