3. INTRODUCTION
 Virtual Reality(VR)?
Virtual Reality refers to a high-end user interface
that involves real-time simulation and interactions
through multiple sensorial channels.
Virtual reality is a computer generated world
with which the user can interact.
Interaction can vary from looking around to
interactively modifying the world.

4. HISTORY OF VR
1950’s visionary cinematographer
Morton H Eilig 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.
HISTORY OF VR

6. TYPES OF VR SYSTEM
 Immersive Virtual Reality
 Augmented Virtual Reality
 Desktop (Window on a World) Virtual Reality
 Video Mapping Virtual Reality

7. IMMERSIVE VR
 It is basically a feeling of involvement of the user in the
virtual world .
 The user has no visual contact with the physical word.
 Often equipped with a Head Mounted Display.
 This unique combinations where
the user can immerse as well
interact with the simulations
is known as Telepresence

8. DESKTOP VR
 Desktop-based virtual reality involves
displaying a 3-dimensional virtual world on a
regular desktop display without use of any
specialized movement-tracking equipment.
 Modern computer
games can be used
as an example

9. VIDEO MAPPING VR

10. ARCHITECTURE OF VR SYSTEM
 Input Processor, Simulation Processor,
Rendering Processor and World Database.

18. CONCLUSION
• Virtual Reality is a growing industry.
• PC and specialized hardware are getting better, faster and
cheaper because of development in VR.
• In the past, computing power has doubled approximately
every 18 months. If this is the case then we should have a
computer powerful enough to run immersive VR programs in
our own homes by the year 2037.
