The document discusses virtual reality (VR), defining it as an artificial environment created with software and presented to users in a way that suspends their disbelief. It outlines the history of VR from early prototypes in the 1950s-1980s to commercial development in the 1990s. It describes different types of VR systems including immersive, hybrid, and non-immersive. Applications of VR discussed include business (virtual tours, training), training simulations, engineering/design, medical (surgery simulation, therapy), and entertainment (gaming, virtual museums). The conclusion states that VR is a growing industry and will revolutionize gaming as hardware improves to support it.

2. 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
our brain.

4. 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”
was released.

6. The different kinds of Virtual Reality
These different types of devices will all come
together at some point to create a complete set of
VR hardware.
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.

7. TYPES
IMMERERSIVE
HYBRID
SYSTEMS
NON-IMMERSIVE
SYSTEMS

8. IMMERSIVE SYSTEM
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
created environment.

9. HYBRID SYSTEM
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.

10. 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.

11. APPLICATIONS OF VIRTUAL REALITY
BUSINESS
TRAINING
ENGINEERING AND DESIGN
MEDICAL
ENTERTAINMENT

12. BUSINESS
Virtual Reality is used in number of ways by business sector
as following:
 Virtual tours of business environment.
 Training of new project.
 A 360 view of a product.

13. TRAINING
 Virtual Reality environments have been used for training
simulators.
 Examples include flight simulators battlefield simulators for
soldiers , paratrooping etc.

14. ENGINEERING AND DESIGN
VR is widely used in engineering and designing process as-
 It gives better understanding
of designing and facility changes
wherever needed.
 It helps to reduce the time and
cost factor.
Example-building construction , car designing.

15. MEDICAL
 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
disabled.

16. ENTERTAINMENT
 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
 Gaming
 Virtual theme parks

17. CONCLUSION
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 .
