What Is Virtual Reality?
Virtual Reality is the computer-generated
simulation of a three-dimensional image
or environment that can be interacted
with in a seemingly real or physical way
by a person using special electronic
equipment, such as a helmet with a
screen inside (HMD) or gloves fitted with
sensors

History of Virtual Reality
1950’s – The Sensorama
Morton H Eilig’s was a visionary cinematographer who built a single user console
called sensorama.This enable the user to watch television in three dimensional
way.
1960 – First VR Headset
Morton H Eilig’s next invention, this was very limited in its uses, with no sound, or
any form of user interaction, just 3D vision.
1965 – The Ultimate Display
This was a concept put forward by Ivan Sutherland, which was the blueprint of
what we call VR today. He suggested a 3D world, maintained in real time, and the
ability for the user to interact with it.
1987 – The term is “virtual reality” is coined
Jaron Lanier coined the term virtual reality, and developed a range of expensive
virtual reality gear.
1991 – VR Arcade
Now players could use goggles, connect with one another and play video games.

1999 – The Matrix
In 1999, film The Matrix hits theatres. The film features
characters that are living in a fully simulated world, with
many completely unaware that they do not live in the
real world. Although some previous films had dabbled in
depicting virtual reality, such as Tron in 1982
and Lawnmower Man in 1992, The Matrix has a major
cultural impact and brought the topic of simulated reality
into the mainstream.
21st Century VR
With the rapid advancement of computer technology,
and as devices get smaller and more powerful, VR
developments are coming thick and fast. With big
companies like Samsung and Google investing heavily in
VR, and the Oculus Rift being valued at £2bn, it is
expected that virtual reality will become more and more
advanced.

Types Of Virtual Reality
I. Immersive VR
II. Non Immersive VR
III.Tele presence VR

Immersive 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.
Ex.HMD or CAVE.

Non Immersive Virtual Reality
Large display but does
not surround the user.
Desktops , LCD TV’s
Ex.Playstations

Tele presence Virtual Reality
It is exactly what it sounds like: tele, “at a
distance”, and presence, “being present”.
The sensors are therefore controlled and
operated remotely by the user. Consider bomb
disposal robots, undersea exploration, and
drones as being operated via telepresence VR.

Devices Used In VR
cave Data gloves
Head
mount
display
Data
suits

Applications Of Virtual Reality
Used in games In medical science

Used in education systems Used in air force training

Pros And Cons Of Virtual Reality
PROS CONS
Virtual reality
creates a realistic
world.
It enables user to
explore places.
It makes education
more easy.
Equipments used in
VR is very expensive.
In this technology
we cant move as we
can use in the real
world.

Future of Virtual Reality
o Virtual reality is a growing industry.
o 3D interfaces will replace the windows based
ones.
o Phone manufacturers will give free VR
headsets.
o Revolution in gaming industries.
o Low price.

Conclusion
• As every generation is known by its
technology.
• For our parents it was internet , for us its I-
phone
• And for the future generation it will be virtual
reality.
