3. What is
VR?
VR is the illusion of the three
dimension,interactive,computer-
generated reality,where sight
,sound and sometimes even touch
are stimulated to create
pictures,sounds and objects that
actually seem real.

4. Introduction
Why VR?
VR is able to immerse you in a
computer- generated world of your
own making room,city. The interior
of human body.with VR,you can
explore any uncharted territory of
the human imagination.

5. History of VR
Today’s VR technologies build
upon ideas that date back to the
1800s,..
The use of the term VR however,
was first used in the mid-1980s
when Jaron Lanier, founder of VPL
Research, began to develop the
gear, including goggles and gloves,
needed to experience what he
called “VR.”

6. Types of virtual reality
> Immersive VR
> Telepresence
> Mixed reality

7. Immersive System
The next step beyond the Window
on World view is the immersion
using a virtual headset. By
removing its users from the
physical world, and placing them in
a virtual world, the sharp visuals
and crisp audio delivered via the
HMD can help them escape
everyday life and explore a far-off
land.

8. Telepresence
Telepresence is exactly what it
sounds like: tele, “at a distance”,
and presence, “being present”.
The sensors are therefore
controlled and operated remotely
by the user. Consider bomb
disposal robots, undersea
exploration, and drones as being
operated via telepresence VR.

9. Mixed Reality
This is where computer generated
inputs are brought together with
telepresence inputs or the user’s
view of the real world to create a
valuable output.This could be a
fighter pilot’s view of maps or data
points displayed inside his helmet
or a surgeon being able to view
real-time patient information during
surgery .
