WHAT IS VIRTUAL REALITY?
Virtual reality (VR) is an artificial environment that is
created with software and presented to the user in
such a way that the user suspends belief and
accepts it as a real environment.
Plainly speaking , its about seeing the imaginary
world and not the real one .Seeing ,hearing ,smelling
, imaginary world is a simulation running in a
computer . The sense data is fed by some system to
HISTORY OF VIRTUAL REALITY
1950’s visionary cinematographer Mortor Heilig build a
single user console called Sensorama.This enabled the
user watch television in three dimension ways.
In 1961,Philco Corporation Engineers developed the first
HMD(Head Mount Display) known as Headsight.
In 1965,IVAN SUTHERLAND envisioned what he called
the “ULTIMATE DISPLAY” (concept including interactive
graphics and force-feedback devices).
In 1988 commercial development of VR beggar and in
1991,first commercial entertainment system “Virtuality”
The different kinds of Virtual Reality
These different types of devices will all come
together at some point to create a complete set of
However, there will remain a number of different
types of Virtual Reality systems. One way to
distinguish one from another will be the mode with
which it interfaces with its users. The following are
just some of those modes.
Immersive virtual reality (immersive VR)
is the presentation of an artificial
environment that replaces user’s
real-world surroundings convincingly
enough that they are able to suspend
disbelief and fully engage with the
Hybrid reality, sometimes referred to as mixed reality, is the
merging of real and virtual worlds to produce new environments
and visualizations where physical and digital objects co-exist
and interact in real time.
NON IMMERSIVE SYSTEMS
Non Immersive systems is anything that doesn’t alter your
location or reality. 2D applications like Quora, or Facebook,
allows you to watch video but it doesn’t add you to the
location and allow you to interact.
Virtual Reality is used in number of ways by business sector
Virtual tours of business environment.
Training of new project.
A 360 view of a product.
Virtual Reality environments have been used for training
Examples include flight simulators battlefield simulators for
soldiers , paratrooping etc.
ENGINEERING AND DESIGN
VR is widely used in engineering and designing process as-
It gives better understanding
of designing and facility changes
It helps to reduce the time and
Example-building construction , car designing.
Healthcare is one of the biggest adopters of
virtual reality which encompasses
surgery simulation , phobia treatment,
robotic surgery and skill training.
VR finds an application in nursing ,
desntistry and health issues for the
The entertainment industry is one of the most
enthusiastic advocates of virtual reality, most noticeably
in games and virtual worlds.
Virtual Museum, e.g. interactive exhibitions
Virtual theme parks
Virtual Reality is a growing industry
PC and specialized hardware are getting better and
faster because of development in VR.
Huge demand for VRML programmers in near future.
Revolution in gaming industries .
