Introduction
What is VR?
 Virtual Reality 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.

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

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 VIRTUAL CONTACT with the
Physical World
 Often equipped with a Head Mounted Display(HMD)

TYPES OF VIRTUAL REALITY
 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 Immension.

 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.

Technologies of Virtual Reality :
 Binocular Omni-orientation Monitor :
 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.

 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.

 Software :-
 Vizard Virtual Reality.
 Virtual Reality Studio.
 Sense8 World Tool Kit.
 Multiverse.

ARCHITECTURE OF VIRTUAL REALITY :

APPLICATIONS :-
Entertainment and Movies :-
360-Degree camera or VR Camera,that have
the ability to record in all directions.
VR Camera are used to create images and
videos that can be viewed in VR.
The experience allows users to interact with
the Characters and Words.

 BIOLOGICAL :-
 Practise Performing Surgery.
 Perform Surgery on a remote patient.
 Teach new skills in a safe , controlled
Environment.

 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.

 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.

ADVANTAGES AND DISADVANTAGES :-
Virtual reality creates a Realistic World.
It enables users to explore Places.
Virtual Reality makes Education more Easier.
The Equipment used in virtual reality is more expensive.
It consists of complex technology.
In Virtual reality environment ,we can’t move by our own like in the
real World .

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……
