Virtual Reality (VR) is the illusion of a
Three-Dimensional, Interactive,
Computer-Generated Reality, where
Sight, Sound, and sometimes even
Touch are simulated to create Pictures,
Sounds, and Objects that actually seem
real.

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.

History of VR :-
In 1950s, flight simulators were built by
US Air Force to train student pilots.
In 1965, a research program for computer
graphics called “The Ultimate Display”
was laid out.
In 1988, commercial development of VR
began.
In 1991, first commercial entertainment
VR system "Virtuality" was released.

Types of Virtual Reality
 Immersive VR :-
Completely immerse the user's
personal viewpoint inside the Virtual
3D- World.
The user has No Visual Contact with
the physical world.
Often equipped with a Head Mounted
Display (HMD).

 Window on World (WOW):-
 Also known as Desktop VR.
 Use of a Monitor to display
the visual world.
 Does Not require Special Hardware.
 Low Cost , Low Performance,
Less Immersion.

Types of Virtual Reality
 Telepresence :-
Real-time Telepresence-
Interaction are Reflected to some real
World objects.
Delayed Telepresence
Interactions are Recorded, and later
Operations are applied to the real-world
object.

Types of Virtual Reality
 Augmented Reality :-
 The seamless merging of Real space and
Virtual space.
 Integrating the Computer-Generated
Virtual objects into the Physical world
which become in a sense an equal part of
our natural environment.

 Binocular Omni-Orientation Monitor (BOOM) :-
Technologies of Virtual Reality
 3-D Display device suspended
from a weighted boom that can
move freely.
 Head-coupled stereoscopic
display device.
 Convenient to use.
 Fast and accurate built-in
tracking.

Technologies of Virtual Reality
 Head Mounted Display(HMD) :-
 A Helmet or a Face mask
providing the visual and auditory
displays.
 Use LCD to display stereo images.
 May include built-in Head-tracker
and Stereo headphones.

Technologies of Virtual Reality
 Cave Automatic Virtual Environment (CAVE) :-
 Provides the illusion of Immersion by
projecting Stereo images on the walls and
floor of a room-sized cube.
 A Head tracking system continuously
adjust the stereo projection to the current
position of the Leading Viewer.

15Applications :-
 Entertainment and Movies :-
 360-Degree cameras or VR cameras,
that have the ability to record in all
directions.
 VR cameras are used to create
images and videos that can be viewed
in VR.
 The experience allows users to
interact with the characters and
worlds.

Applications :-
 Biological :-
 Practice performing surgery.
 Perform surgery on a remote
patient.
 Teach new skills in a safe,
controlled environment

17.
17Applications :-
 GAMES :-
 The use of graphics, sound and
input technology in Video
games can be incorporated into VR.
 The VR Technology gives feedback
through visual, auditory, haptic and
other sensory systems.

18.
18
Applications :-
 Education and Training :-
 Provide learners with a Virtual
Environment where they can
develop their skills without the real-
world consequences of failing.
 The fully Immersive training
environment allows to train through
a wide variety of Terrains,
situations and scenarios..

19.

Current Problems and Future Work :-
 Motion sickness / Simulator sickness
 Low-Accuracy
 Expensive
 Bit lack of integration between application packages.
 Cost-saving
 High-level contact between participants in VR.
 High-Accuracy system

Conclusion :-
 Visualization of complicated, large data is
helpful for understanding and analysis.
 VR offers us a new way to interact with
computer and real life.
 VR enables us to experience the virtual world
that is impossible in real world.
 VR is changing our life, eventually VR will
increasingly become a part of our life.
 The Best of VR is Yet to Come . . .
