Virtual Reality & Oculus Rift Technology...

1. ALL ABOUT VIRTUAL REALITY
& OCULUS RIFT

2. WHAT IS VIRTUAL REALITY?
 Virtual Reality refers to a high-end user interface that
involves real-time simulation and interactions through
multiple sensorial channels.
 Virtual Reality means feeling an imaginary (virtual)
world, rather than the real one. The imaginary world is
a simulation running in a computer. The sense data is
fed by some system to our brain.
 Virtual Reality allows a user to interact with a
computer-simulated environment, be it a real or
imagined one.

3. HISTORY OF VIRTUAL REALITY
 1950’s visionary cinematographer Morton
Heilig built a single user console
called Sensorama. This enabled the user
watch television in three dimensional ways.

4.  In 1961, Philco Corporation engineers developed
the first HMD known as the Headsight.

5.  It was in 1965 IVAN SUTHERLAND envisioned
what he called the “Ultimate Display.”
 In 1988, commercial development of VR began.
 In 1991, first commercial entertainment VR
system "Virtuality" was released.

9. Applications
 Education & Training
- Driving simulator
- Flight simulator
- Ship simulator
- Shooting simulator

10. Applications
 Movies -Virtual reality is applied in 3-D movies to try and
immerse the viewer into the movie and/or virtual setting and
environments.
 Video Games -Virtual reality is evident in video games. Now you
can physically interact with a game by using your body and
motions to control characters and other elements of the game
that years ago people would only imagine.
 Education and training –Training and education is done through
virtual reality because it can prepare you for many dangerous
jobs and put the worker in real scenarios without the risk of them
being hurt. Doing this enables them to fully train and educate
themselves in almost any situation possible so that they’re ready
and well equipped for the job.Virtual reality can give them the
experience they need without actually putting them or others in
danger.

11. Business:
 Virtual reality is being used in a number of
ways by the business community which
include:
 Virtual tours of a business environment.
 Training of new employees.
 A 360 view of a product.

12. Training:
 Virtual reality environments have been used
for training simulators.
 Examples include flight simulators, battlefield
simulators for soldiers,paratrooping.

14. 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.
Examples: Building construction, car designing.

15. Medical:
 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.

16. 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
 Gaming
 Virtual theme parks

20. Oculus Rift
 Oculus Rift was invented by a virtual
reality enthusiast named Palmer Luckey.
 The Oculus Rift is a virtual reality head
mounted display, being developed by
OculusVR, a division of Facebook.
 The Oculus Rift is a virtual reality headset
that lets players step inside their favorite
games and virtual worlds.

21. How it works
 It uses a 7 inch LCD display screen with a
resolution of 1280 by 800 pixels.
 Screen is divided into 640 by 800 pixels per
eye, with a fixed distance between lens
centers.
 User can view the screen through two lens
cup.

22. How it works
 Back view of Oculus Rift.

24. How it works
 A control box is used to hook the headset up
to your computer.
 Control box includes HDMI port, mini USB
port, DVI pot and DC power connection port.
 Control box also contains five buttons for
controlling contrast, brightness and power.

25. How it works

26. Developer Version
 In August 2012, Oculus announced the "dev
kit" version of the Oculus Rift.
 In March 2014, Oculus announced the
upcoming Devkit 2 (DK2) which they
expected to begin shipping in July 2014.

27. Consumer Version
 A consumer version of the Rift is in
development, which will be aimed at a
general market and feature improved
components.
 Improved positional tracking, higher
resolution, and wireless operation are some
of the features under consideration.

OCULUS
“Our mission is to make the world more
open and connected. For the past few
years, this has mostly meant building
mobile apps that help you share with the
people you care about. We have a lot more
to do on mobile, but at this point we feel
we're in a position where we can start
focusing on what platforms will come next
to enable even more useful, entertaining
and personal experiences…
“After games, we're going to make Oculus a
platform for many other experiences.
Imagine enjoying a court side seat at a
game, studying in a classroom of students
and teachers all over the world or
consulting with a doctor face-to-face -- just
by putting on goggles in your home.
“This is really a new communication
platform. By feeling truly present, you can
share unbounded spaces and experiences
with the people in your life. Imagine sharing
not just moments with your friends online,

Google’s response to the $350
Oculus Rift Developer’s Kit is
this do-it-yourself “Oculus Thrift”
which turns Android devices into
portable VR viewers, using an
open source software
developers kit.

36. CONCLUSION
• 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.
