Virtual reality - Google Cardboard

 Virtual Reality (VR) is a way for humans to
visualize, manipulate and interact with
computers and extremely complex data.

 In 1965, Ivan Sutherland expressed his ideas
of creating virtual or imaginary worlds.
 In 1969, he developed the first system to
surround people in three dimensional
displays of information
 The concept of virtual reality was mainly
used by the United States. They used it as
flight simulators to train pilots

 Cyber sickness
 Low-fidelity
 Very expensive

Virtual Reality Headsets

How normal people make use of
the virtual reality technology?
How to make it available for
every person’s use?
How to counter the cost incurred
in buying the heavy gadget?
Question Arises!!!!!!

 This headset is designed by Google, But there is no official
manufacture for this device.
 It takes the real world and alters certain parameters to completely
change the viewing experience
 The Google Cardboard was part of a Google 20% project where
employees are allowed to work on side projects in addition to their
normal everyday duties

1) Cardboard:
E-Flute corrugated cardboard sheet
Minimum size: 8.75in (22cm) by 22in (56cm), and 0.06in
(1.5mm) thickness.

2) Lenses:
Two Asymmetric-BiConvex optical lenses. Lenses that have a
45mm focal distance might work. Biconvex lenses work best
because they prevent distortion around the edges.

3) Magnet:
One neodymium ring magnet and one ceramic disk magnet

 First you need to download the Cardboard app from Google Play.
It's a large app - 74.63MB

 Google Cardboard works by placing your phone at the optimal
distance away from the lenses.

 With the Google Cardboard app launched and your phone inside
the headset, you'll feel it vibrate. You can then look left and right
to scroll through the menu.
 The little magnet on the side is actually a quite ingenious design
aspect of Google Cardboard. It's a button!

 Since you can't touch your phone's screen while it's inside the
Cardboard, Google has provided this magnet that, when moved,
acts as if you've pressed your screen.
 It uses your phone's magnetometer, which is usually used for
compass functions, to sense this and control it while it's in the
cardboard

Google provides two software development kits
for developing Cardboard applications, both
using OpenGL: one for Android using Java, and
one for the game engine Unity using C#.

The Cardboard SDK for Android enables
developers familiar with OpenGL to quickly
start creating VR applications.
It provides following features:
 Lens distortion correction.
 Head tracking.
 3D calibration.
 Side-by-side rendering.
 Stereo geometry configuration.
 User input event handling.

Cardboard SDK requires manifest tags.

Implementing per-eye configuration

 YouTube 360 contains many VR
videos under their channel
#360Video.
 Google has started new project
known as Google JUMP
 Google cardboard camera app.

 As movement of people is becoming more and
The ability of Virtual Reality to produce realistic
worlds of data, objects and environments, with
which the users can interact and manipulate in a
realistic and an intuitive manner, opens up a vast
wealth of possibilities for work-related
applications.
 The concept of Virtual Reality provides an
innovative mix of entertainment, education and
State-of-Art. Virtual reality technology will
transport guests to different worlds.
