Virtual reality uses computer technology to create simulated environments. It was coined in 1987 and has seen significant research development. There are several types including desktop, immersive, and mixed reality. Virtual reality has many applications such as architecture, medicine, engineering, entertainment, training, and manufacturing. It provides advantages like creating realistic experiences and experimenting safely, but also has disadvantages like requiring expensive equipment and complex technology.

4. Virtual Reality is the use of computer
Technology to create simulated environment.
Unlike traditional user interfaces, such as helmet
with screen inside or gloves fitted with sensors.
The term ‘virtual reality ‘ was coined by
jaron lanier in 1987 during a period of intense
Research activity into this form of technology
VPL(Visual programming language)research
patents were later acquired by
Sun micro systems in 1999

6. The definition of virtual reality comes,
naturally, from the definitions for both
‘virtual’ and ‘reality’.
The definition of ‘virtual’ is near And reality
is what we experience as human beings.
So the term ‘virtual reality’ basically means
‘near-reality’. This could, of course ,mean
anything but it usually refers to a specific
type of reality emulation.
7. * The concept of virtual reality is basically
from 1950.
* Then in 1965-Ultimate Display.
* 1966-HMD was Invented.
* People became aware of VR in 1990.
8. NASA, The department of Defense and the National
science foundation founded much of the research and
development for virtual reality projects. $80,000 was
contributed by the CIA for research purpose to Sutherland.
After that in 1984, Micheal Mc greevy, a computer scientist
started to experiment with virtual reality technology as path
to advance human computer interface(HCI) designs. HCI
still is a domination factor in research. It further led the
media picking up on the idea of virtual reality within
a couple of years .
Jaron Lanier coined the term virtual reality in 1987. today
virtual reality plays a big part in the every day lives of the
world’s population.
13. Also called as Desktop VR.
Using a conventional computer monitor to display the
3D virtual world.
14. A variation of visualizing complete computer
generated worlds.
Links remote sensors in the real world with the senses
of a human operator. The remote sensors might be
located on a robot. Useful for performing operations in
dangeroust environments.

16. Merging the Telepresence and Virtual reality systems
gives the mixed virtual reality or seamless simulation.
A fighter pilot can see computer generated maps and
scenes data displays in there fancy HMD that is
Helmet visor or cockpit displays.
In this type of virtual reality user can see, Hear virtual
world and can operate that world by using
Telepresence.
19. For many years virtual reality has been used to establish
models of architectural models and buildings before
construction begins.
It can also be used to reconstruct building which is
collapsed or damaged or to determine how this
happened & the steps needed prevent the situation in the
future.
20.
21. The medical field uses virtual reality in many ways.
It can be used in medical studies to enable students to
know the human body structure.
The most common implementation of the technology is to
combine images provided by other scans and merge
them to present the details, using medical imaging
technology
This helps doctors diagnose problems without performing
surgery.
22.
23. Engineering and Design:
It can be used in scientific research laboratories so that
scientist can be easily research on the specific topic.
VR is widely used in engineering and designing
process.
It gives better understanding of the design and
facilitates changes wherever necessary
It helps to reduce the time and cost factor.
Examples: Building construction field.
24.
25. Entertainment:
The entertainment industry is one of the
most enthusiastic advocates of virtual reality,
most noticeably in games and virtual worlds.
Gaming
Film and theaters
Virtual theme parks
26.
27. Training and Manufacturing Field
It can most widely used in Military training for the soldiers
to get familiar with different areas in the battlefield
United states uses VR as flight simulator to train pilots.
It is used in Hardware parts manufacturing field
28. Advantages and disadvantages
Advantages:
Virtual reality creates a
realistic world
It enables user to explore
places.
Through virtual reality user
can experiment with an
artificial environment.
Virtual reality make the
education more easily and
comfort.
Disadvantages:
The equipments used in Virtual
reality are very Expensive.
It consists of complex
technology.
In virtual reality environment
we cant move by our own like in
the real world .
29. The sole objective of virtual reality is to give the
user an environment as realistic as possible and
a thrilling sensory experience.
Web is very suitable for VR applications, but the
proper technology is not yet there
VR introduces a new way of interacting with
computers
