Virtual Reality is one of emerging concepts in the present tech industry. And it has that potential to shape the world in a more interactive way. (My second presentation at Arena)

1. VIRTUAL
REALITY

2. 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.
WHAT IS VIRTUAL REALITY?

3. HISTORY
1. 1950’s visionary cinematographer Morton Heilig built
a single user console called Sensorama. This enabled
the user watchtelevision in three dimensional ways.
2. In 1961, Philco Corporation engineers developed the
first HMD known as the Headsight.
3. It was in 1965 IVAN SUTHERLAND envisioned what
he called the “Ultimate Display.”
4. In 1988, commercial development of VR began.
5. In 1991, first commercial entertainment VR system "Virtuality"
was released.
1950 - 2000

4. IMPROVEMENT IN TECHNOLOGY
2000 - 2016
1. By 2007, Googleintroduced Street View, a service that shows
panoramic views of an increasing number of worldwide positions
such as roads, indoor buildings and rural areas. It also features a
stereoscopic 3D mode, introduced in 2010.
2. In 2013, Valve discovered and freely shared the breakthrough of
low-persistence displays which make lag-free and smear-free
display of VR content possible.
3. By 2016 there were at least 230 companies developing VR-
related products. Facebook has 400 employees focused on VR
development; Google, Apple, Amazon, Microsoft, Sony and
Samsung all had dedicated AR and VR groups.

5. TYPES OF VIRTUAL REALITY
Head-mounted Displays (HMDs)
● Head-mounted displays, or HMDs, are probably the most
instantly recognizable objects associated with virtual
reality.
● HMDs are not only used in virtual reality gaming, they’ve
also been utilized in military, medical and engineering
contexts to name a few. As seen in educational films such
as The Terminator, these devices can be used to create
something called augmented reality, which overlays digital
information through an HMD filter onto the real world

6. TYPES OF VIRTUAL REALITY
CAVE Fully Immersive Virtual Reality
● This is the name given to a virtual environment in which
the person is fully immersed within it. CAVE stands for
CAVE Automatic Virtual Environment and takes the form
of a cube-like space in which images are displayed by a
series of projectors.
● A main feature of the CAVE system is interaction. The
combination of interaction and total immersion is known
as telepresence in which a person can literally lose
themselves within the virtual environment.Interaction
takes place using a variety of input devices, for example, a
joystick, wand or more commonly, a haptics device, i.e.
data glove. This enables the person to interact with
objects, for example, pulling, twisting or gripping by means
of touch. The ability to do this is known as haptics.

7. APPLICATIONS OF VR
Training
● Virtual reality environments have been used for training simulators..
● Examples include flight simulators, battlefield simulators for
soldiers,paratrooping.

8. APPLICATIONS OF VR
Engineering and Design
● 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.

9. APPLICATIONS OF VR
MEDICINE
● Healthcare is one of the biggest adopters of virtual reality which encompasses
surgery simulation, phobia treatment, robotic surgery and skills training.
● VR finds its application in nursing, dentistry, health issues for the disabled.

10. APPLICATIONS OF VR
Entertainment
● The entertainment industry is one of the most enthusiastic
advocates of virtual reality, most noticeably in games and virtual
worlds.
● Virtual Museum, e.g. interactive exhibitions
● Virtual theme parks

11. APPLICATIONS OF VR
Gaming
Virtual reality gaming is where a person can experience being in a three-
dimensional environment and interact with that environment during
a game. This is an essential part of the game.

12. APPLICATIONS OF VR
3D INTERNET
And let’s not forget the internet. There are games programmers who like the
idea of a three dimensional internet in which you are able to explore
websites in a dynamic way. Rather than clicking on a link and scanning the
information on a web page you will be able to physically touch that page and
manipulate it. Think of a web page as a location which you can explore at
your leisure
Virtual reality languages
VRML (Virtual Reality Modelling Language): this is the earliest VRlangua
X3D: this has since replaced VRML
3DML: this enables someone to visit a website via a plug in
COLLADA (Collaborative Design Activity): this allows file exchanges.

14. THE FUTURE
● Virtual Reality is a growing industry.
● PC and specialized hardware are getting better, faster and cheaper because
of development in VR.
● In the past, computing power has doubled approximately every 18 months. If
this is the case then we should have a computer powerful enough to run
immersive VR programs in our own homes by the year 2037.
1999
2029
10% of the world’s computing power was non-human
99% of world’s computing capacity will be non-human

VR is avery instance visual
Experience and having the most
Powerful PC is the only way to
Deliver certain experiences
