What is Virtual Reality?


Virtual reality technology :
applies to computer
-
simulated environments that can simulate physical
presence in places in the real world, as well as in
imaginary worlds


Virtual reality allows users to interact in a new world
by using just an input device such as a keyboard or
with the new technology a wired glove.


There are a wide range of uses of virtual reality
technology. For example:


simulations for pilot or combat training


A Brief History


1920


vehicle simulators were introduced


1966


Tom Furness introduced the flight simulator


1968


the first
augmented reality (AR) head mounted
display (HMD)

was developed by Ivan Sutherland and his
student Bob
Sproull


1977


at MIT the Aspen Movie Map was created, which is
one of the earlier
hypermedia

systems created


1985


the first
“goggles and gloves”

was created which was
titled the system of the decade


1991


the virtual reality concept of “driving on Mars” with a
rover was created by a MIT graduate and a NASA scientist.

Seven Concepts of Virtual Reality
Technology


Simulation



Interaction


Artificiality


Immersion


Telepresence


Full
-
body immersion


Network


Simulation:

(computer science) the technique of
representing the real world by a computer program; "a
simulation should imitate the internal processes and
not merely the results of the thing being simulated"



Interaction:

is a kind of action that occurs as two or
more objects have an effect upon one another. The
idea of a two
-
way effect is essential in the concept of
interaction, as opposed to a one
-
way causal effect



Artificiality:

the state of being unreal or unnatural



Immersion:

the state of consciousness where an
immersant's

awareness of physical self is diminished or lost by being surrounded in
an engrossing total environment; often artificial



Telepresence
:

refers to a set of technologies which allow a person to
feel as if they were present, to give the appearance that they were
present, or to have an effect, at a location other than their true location.



Full
-
body immersion:
the basis of technology that allows players to
experience a complete out of body experience as the enter into a world
of reality. Players are able to smell, hear and see this created world they
play in and have it seem completely real.



Network:

is a real
-
time, two player business simulation game
developed by David
Mullich

for the Apple II in 1980. Two players play
competitively against the computer, each taking the role of the
programming chief for a major television network.


Six Virtual Realities



Anxiety Therapy


VR Training Programs


Multiplayer Online Gaming


Medical Procedures


Project Natal


The Cave





YOU ARE THE CONTROLER

Anxiety Therapy


For many soldiers who

suffer with post traumatic

stress disorder use

anxiety therapy
.


Therapists use anxiety

therapy to allow those who

suffer with anxiety to relive

their pain and allow them

to talk and understand

there fear.

Examples

for the use of

anxiety therapy:


Soldiers who have P.S.D.


Fear of flying


Fear of elevators


Quitting smoking

VR Training Programs


VR Training Programs allows those using it to feel a complete immersion into
the area of work. The first use of VR Training Programs was the fight simulator,
created in 1966.


Examples:


including Iraqi cultural situations and battlefield simulators for soldiers


counter
-
terrorism


Paratrooping


Welding


mining training

Multiplayer Online Gaming


Multiplayer Online Gaming

allows
players to feel that full
-
body
immersion. Players are able to create
their own
avatar

and live in a whole
new world.


Complete imaginary worlds are
created and populated by the avatars
of those playing.


It is a means of communication and
socialization with people around the
world


Examples:


World of
Warcraft


Second Life

Medical Procedures

Due to the development of technology,
there have been advances in numerous
medical techniques using virtual reality.
Numerous medical surgeons have began
using these technologies to help with
their surgeries and have had a higher
success rate.


Because of the use of virtual reality and
robotics in surgical training and
surgeries, the use of this new technology
will be beneficial in the long run and
will continue to be developed in the
future.

Uses of Virtual Reality Technology:


Many doctors are beginning to use robotics when
working in certain medical fields. Examples of these
are orthopaedics and cardiology.


Many other medical practices are using various
types of virtual reality when treating patients.
Examples of this is in cases of mental health,
anaesthetics, and emergency medicine








New technologies, in particular virtual
reality and robotics, will have a major impact
on health care in the next decade.

Project Natal


The
project natal

is the newest virtual
reality technology. Project natal has no
controller, keyboard and any other type of
input device. Controlled by the players voice
and motions is the sole method of
interaction with this new device.



The latest craze is Xbox360’s newest gaming
system,
Kinect
.
Kinect

is a very easy system
to set up and is fun for the entire family. A
full
-
body experience of gaming brings
endless hours of entertainment to all those
who play. With the numerous games that
come with
Kinect

there is something for
everyone in the family.

“You are the controller. No gadgets, no
gizmos, just you!”

Kinect

The Cave



Created in 1992,
The Cave

was
first created for research
scientific visionaries. Many
universities today use the Cave
as a means of visualizing data
and demonstrating 3D labs.


The Cave is a full
-
body
immersion into a world of
virtual reality.


Set up as four projectors placed
on the four surrounding walls of
the space used; the Cave offers
multiple players to experience
this new world at once.


Potential idea for Virtual Reality
uses


As technology expands
there will be new and
improved uses for virtual
reality. In London, UK,
three students of
University of London
explored the concept of
virtual reality in
mapping urban
neighbourhoods
.


Goal to have 3D images


Modelling language


VRML


Two types of maps


Static


Dynamic


The following diagram illustrates the five stages to full
interactivity in virtual worlds. Starting with the basic
HTML (Hyper Text Mark
-
up Language) to the full extent
of the third dimensional world.

Conclusion


As technology improves and becomes more and more
advanced the uses to technology will grow. The
concept of virtual reality technology is continuing to
grow today and will continue to grow for the years to
come. From the concept of being in a whole new
world, to simply having a family games night, with the
Xbox360’s
Kinect
, virtual reality is a very complex tool
that has helped with numerous scientific discoveries
and will continue to explore the concept of a virtual
world, where you are the controller.
