Google Cardboard Virtual Reality

 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
 Since then, virtual reality has developed in
many ways to become an emerging
technology of our time.

 Virtual Reality Using Hardware
There is a number of hardware developed for the usage by Virtual
Reality. Among them some are explained below.
 Head Mounted Display :
The Head mounted display consists of two miniature display
screens that produce the stereo scopic images and an optical
position tracking system that tracks the orientation of the humans
head in the Virtual world.

 Virtual Reality Using Software
The most commonly used tools for developing 3d worlds are
VRML v1.0, VRML97, VRML v2.0, 3d Studio max, and other
such software. There are many concepts of developing the
virtual worlds using the software.
 Programming:
The other tool available for developing the virtual worlds is by
programming. There are many programming languages by
which we can develop the virtual worlds. The best one we
prefer is by using VRML v2.0. Prior to this language, people
used to develop the virtual worlds using the traditional
programming language, JAVA.

 Cyber sickness: Cyber sickness is a term to describe motion
sickness experienced by users of head-steered Virtual Reality
systems.
 Low-fidelity: It is a type of sound recording which contains
technical flaws that make the recording sound different compared
with the live sound being recorded.
 Very expensive

 Virtual Reality has made exciting progress over the past several years.
Developing for VR still requires expensive, specializes hardware.
 Thinking about how to make VR accessible to more people, A group
of VR Enthusiasts at Google experimented with using a smart-phone
to drive VR experiences.
Google Cardboard Virtual Reality Headset

 This headset is designed by Google, But there is no official
manufacture for this device.
 In this new Google product, the users are taken to the new world
of virtual reality.
 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
 This is a simple and inexpensive device. You can download apps
meant for this device and enhance your experience of using this
device
 You can also use it to build your own things with the help of this
device.

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.

 Then, by using compatible apps, the lenses create a 3D effect
when held up to your eyes.
 You can even move your head around, and the images will
respond as if you're in the same place as what's displayed on your
screen.
 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

 Difference Between Phone Mode and VR mode

 The cardboard app comes with 7 experiences:
 Earth: Fly where your fancy takes you on Google Earth.
 Tour Guide: Visit Versailles with a local guide.
 YouTube: Watch popular YouTube videos on a massive screen.
 Exhibit: Examine cultural artifacts from every angle.
 Photo Sphere: Look around the photo spheres you’ve captured.
 Street Vue: Drive through Paris on a summer day.
 Windy Day: Follow the story (and the hat) in this interactive
animated short from Spotlight Stories.

 The Android SDK enables applications with features
including:
 Lens distortion correction.
 Head tracking.
 3D calibration.
 Side-by-side rendering.
 Stereo geometry configuration.
 User input event handling.

 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.
