4. • Virtual reality is a computer generated environment that lets you
experience a different reality.
• It is a computer generated, multi-sensory information program which
tracks a user in real time
What is Virtual Reality ?
5. • Virtual reality could recreate sensory
experiences, including virtual taste, sight,
smell, sound, touch, etc.
• Actually virtual reality is the creation of a
virtual environment presented to our
senses in such a way that we experience it
as if we were really there.
6. History of Virtual Reality
• In 1950s, flight simulators were
built by US Air Force to train
student pilot.
• 1950’s visionary cinematographer Morton Heilig built a single user
console called Sensorama. This enabled the user to watch television in
three dimensional ways.
7. • In 1961, Philco Corporation’s
engineers developed the first HMD
known as the Headsight.
• In 1965, a research program for
computer graphics called “The
Ultimate Display” was laid out.
8. • In 1988, commercial development of
VR began.
• In 1991, first commercial
entertainment VR system “Virtuality”
was released.
• In 1992 a method of the showing and
testing of scientific visualizations called
“The CAVE” was created.
9. Types of Virtual Reality
Immersive Virtual Reality
Augmented Virtual Reality
Desktop Virtual Reality
Quick Time Virtual Reality
There are many types of Virtual Reality, including the following:
10. Immersive Virtual Reality
Augmented Virtual Reality
• Immersion into virtual reality is a
perception of being physically present in a
non-physical world.
• The perception is created by surrounding
the user of the VR system in images, sound
or other stimuli that provide an engrossing
total environment.
• Augmented reality does not create a
simulation of reality. Instead, it takes a
real object as the foundation and
incorporates technologies that deepen a
person’s understanding of the subject.
11. Desktop Virtual Reality
• Desktop-based virtual reality involves
displaying a 3-dimensional virtual world on a
regular desktop display without use of any
specialized movement-tracking equipment.
• It is cost-effective when compared to the
immersive VR.
Quick Time Virtual Reality
• Quick Time Virtual Reality allows the
creation of applications without coding.
• It is a photography based VR, an
"immersive" technology with easy to use
software.
12. Uses of Virtual Reality
In Business :
• Virtual tours of a business environment.
• Training of new employee.
In Training :
• VR is used to provide learners with a
virtual environment where they can
develop their skills without the real-world
consequences of failing.
• Examples include flight simulators,
battlefield simulators, driving simulators.
13. In Medical :
• Virtual reality is used in surgery
simulation, phobia treatment, robotic
surgery and skills training.
• VR finds its application in nursing,
dentistry, health issues for the disabled.
In Gaming:
• Obviously, video games are one of the
main applications for virtual reality as
of today.
14. In Entertainment :
• Virtual reality is applied in 3D
movies.
• VR will change how we view live
music by allowing us to attend
virtual concerts.
• VR is widely used in engineering and
designing process.
• It gives better understanding of the
design and facilitates changes wherever
necessary.
In Engineering :
15. Negative influence of Virtual Reality
• Virtual reality can lead to physical,
emotional, and social problems for the user.
• Games, such as Second Life, can be fun
escapes from the world we live in. However,
if abused they can literally become a second
life. The user then cuts his or herself off
from the world socially.
• Tests have been done that show virtual reality
can cause physical harm to senses such as
sight.
16. Future of Virtual Reality
• The future of virtual reality is hard to
predict but one thing’s for sure the world of
entertainment is going to see a lot more of
it.
• Virtual reality is starting to evolve into
video games and movies. The Nintendo
Wii and Project Natal are great examples
of that.
17. • Also many more 3-D movies are being made and maybe in the
near future they will all become more immersive. Only time
will tell.
