3. What is virtual reality?
Virtual reality means feeling the
imaginary(virtual) world ,rather then real one.
The imaginary world is a simulation running in a
computer.
Virtual reality is a term used for computer
generated 3D environments that allow the user to
enter and interact with alternate realities.
The definition of ‘virtual‘ is near and ‘reality’ is
what we experience as human beings.
4. What is virtual reality ? (…cont)
Virtual reality refers to a high end user interface that
involves real time simulation
And interactions through multiple sensorial channels.
In other words,
Virtual reality is a computer generated world with which
user can interact
Interaction can very from looking around to interactively
modifying the world.
5. it makes use of an artificial environment generated by
the computer in which simulates the real environment
virtual reality is an artificially-created three-
dimensional environment constructed with the help of
computers, which people can interact with in the same
way as they do with the real world, using their senses to
navigate and explore it.

6. History
More then one person has
been involved in the
department of this technological
system.
In the 1950s visionary
cinematography Morton heilig
built a single user console
called Sensorama. This
enabled user watch television
in 3 dimensional ways.
8. Immersive virtual reality
Immersion into virtual reality is a perception of being physically present in a
non-physical world.
It is basically a feeling of involvement of user in the virtual world.
Often equipped with head mounted display (hmd).
This unique combination where user can immerse as well as interact with
the simulations is known as telepresence.
Elements of virtual environments that increase the immersivness of
experience
1. Continuity of surroundings
2. Conformance to human vision
3. Freedom of movement
4. Physical interaction
5. Physical feedback
11. Window on world virtual reality
Desktop based virtual reality involves displaying a 3
dimensional virtual on regular desktop display without use
of any specialized movement tracking environment.
Modern computer game can be used as an examples.
16. Application of virtual reality
1)Virtual reality in military :
Virtual reality has been adopted by the military – this includes all three
services (army, navy and air force) – where it is used for training
purposes.
A virtual reality simulation enables them to do so but without the risk of
death or a serious injury. They can re-enact a particular scenario, for
example engagement with an enemy in an environment in which they
experience this but without the real world risks. This has proven to be
safer and less costly than traditional training methods.
18. Virtual reality engineering includes the use of 3D modeling
tools and visualization techniques as part of the design
process. This technology enables engineers to view their
project in 3D and gain a greater understanding of how it
works. Plus they can spot any flaws or potential risks
before implementation.
This also allows the design team to observe their project
within a safe environment and make changes as and
where necessary.
2) Virtual Reality in Engineering:
20. The entertainment industry is one of the most enthusiastic
advocates of virtual reality, most noticeably in games and
virtual worlds. But other equally popular areas include:
Virtual Museums, e.g. interactive exhibitions
Galleries
Theatre, e.g. interactive performances
Virtual theme parks
Discovery centers
3) Virtual Reality in Entertainment:
22. This technology enables trainee surgeons to gain
valuable experience but in a safe environment.
They learn skills and techniques without causing
harm to patients and receive constant feedback as
they do so.
4) Virtual reality in surgery:
24. Advantage and disadvantage of virtual reality
advantage disadvantage
Virtual reality creates a realistic world. The equipment used in virtual reality
are very expensive.
It enables user to explore places. It consists of complex technologies.
Through virtual reality user can
experience an artificial environment.
Prolong usage may cause
psychological or mental stress.
Great for training. In virtual reality environment we cant
move by our own like in the real one.
