3. What is Virtual Reality ?
Virtual Reality refers to a high-end user interface that
involves real-time simulation and interactions through
multiple sensorial channels. Virtual Reality is often
used to describes a wide variety of applications ,
commonly associated with its immersive, highly
visual, 3D environments, the development of CAD
software, graphics hardware acceleration, head
mounted displays, database gloves and
miniaturization have helped popularize the concept.

4. HISTORY OF VIRTUAL REALITY
 1950’s visionary cinematographer
Morton Heilig built a single user
Console called Sensorama. This
Enabled the user watch television
In three dimensional ways.

5. In 1961, philco Corporation engineers developed the first HMD
known as the Headsight

6. It was in 1965 IVAN SUTHERLAND envision what he called the
“Ultimate Display”.
In 1988, commercial development of VR began.
In 1991,first commercial entertainment VR system “Virtuality” was
released.

7. TYPES OF VIRTUAL REALITY
VR System can be divided into three groups
Non-immersive systems(like workstation)
See information about the real world , presented via
computer location based services, GIS
Augmented reality systems(like HMD)
Stay in real world, but see simulated objects.
Immersive systems(like CAVE)
See simulated world and “be” in that simulated world.

9. Augmented reality
 Computer generated inputs
merged with the user’s view
of the real world
 The seamless merging of real space
and virtual space.
 Integrate the computer – generated
virtual objects into the physical world
which become in a sense an equal
part of our natural environment.

10. Augmented reality

11. Immersive system(CAVE)
The term ”CAVE” refers to any virtual reality system that
user multiple walls with multiple projectors to
immerse users in a virtual world. The CAVE is used for
visualizing data, demonstrating 3D environments, and
virtual testing component parts of newly developed
engineering projects.

12. DEVICES OF VIRTUAL REALITY
 INPUT DEVICES:-
The data glove
3D Mouse and Space Ball
Motion trackers

13. Out put devices
 Head-mounted display(HMD)
 BOOM(Binocular Omni-Orientation Monitor)
 Haptic interfaces and tactile feedback for VE
applications

14. APPLICATIONS OF VR
 Architecture
 Medicine
 Engineering & Design
 Entertainment
 Training
 Manufacturing

15. ARCHITECTURE DESIGNING
 For many years virtual reality
has been used establish models
Of architecture models and
Buildings before construction
design

16. MEDICAL FIELD
This helps doctors diagnose
Problems without performing
surgery

17. ENGINEERING & DESIGNING
• VR is widely used in engineering and designing.
• It gives better understanding of the design and
facilitates changes wherever necessary
• It helps to reduce the time and cost factor

18. ENTERTAINMENT FIELD
In high definition televisions
VR is used for highly resolute
Output also for motion games

19. TRAINING FIELD
United states uses VR as flight
Simulator to train pilots
With VR training huge saving
Of fuel, electricity, wear & tear
Could be effected

20. Advantages of Virtual reality
 Virtual reality creates a realistic world
 It enables user to explore places
 Through virtual reality user experiment with an
environment
 Virtual reality make the education more easily and
comfort

21. Disadvantages of Virtual reality
 The equipments used in virtual reality are very
expensive
 It consists of complex technology
 Costly investment

22. CONCLUSION
 Virtual reality is growing industry
 VR introduces a new way of interacting with
computers
 The best of VR is yet to come
 Web is very suitable for VR applications, but the
proper technology is not yet there
 1999 :-10% of the world’s computing power was non-
human
 2029:-99% of the world’s computing capacity will be
non-human
