What is Google
Cardboard?
It's simply a design - one you can either buy as a kit
from a manufacturer or use to build your own - that utilizes cardboard and a
pair of 40mm focal distance lenses to turn your phone into virtual reality
headset. It also uses magnets, velcro, and a rubber band to keep everything in
place.
Once put together, users set their phone into it and look
through the lenses. In combination with compatible apps, this simple setup can
turn interacting with your handset's screen into a seemingly real-world
experience.
Now, Here's what
you need to get started and u can
make at your home :
1. Cardboard :- Corrugated cardboard sheet, preferably E Flute (corrugated cardboard comes in a variety of thicknesses called "flutes"), available at many art supply stores and online . For best results, you should look for strong, thin cardboard (sturdy shoe box rather than moving box). Minimum size: 8.75in (22cm) by 22in (56cm), and 0.06in (1.5mm) thickness.
2. Lenses :- This is the trickiest component. Lenses that have a 45mm focal
distance might work. Biconvex lenses work best because they prevent distortion
around the edges. We used the Durovis OpenDive Lens Kit available on Amazon.com
3. Magnets :- One neodymium ring magnet and one ceramic disk magnet - like this
or this. Approximate size: 0.75in (19mm) diameter and 0.12in (3mm) thickness.
4. Velcro :- Two strips of regular strength adhesive-backed velcro. Approximate
size: 0.75in (20mm) by 1.25in (30mm).
5. Rubber band :- One rubber band, to prevent the phone from sliding out.
Minimum length of 3.2in (8cm).
6. NFC tag (optional) :- One sticker NFC tag. Program it with the URL cardboard://v1.0.0
6. NFC tag (optional) :- One sticker NFC tag. Program it with the URL cardboard://v1.0.0
7. You'll also need a ruler, glue, and scissors, an X-acto knife, or access to
a laser cutter.
How to make a Google Cardboard VR headset
Step 1. If
you've ever completed an old jigsaw that you've found lying in the loft, you'll
know how important it is to make sure you have all the pieces before you begin.
In the box you should find two lenses, two magnets, two Velco pads and three
pieces of cardboard. You'll need to supply your own Android phone, obviously,
which must run Android 4.1 or later and have no larger than a 6in screen.
Step 2. This is the annoying bit. The cardboard has
been pre-cut, but the unwanted material has not been removed. You'll need to
carefully press out the cutouts without ripping or bending the card. That
shouldn't be too difficult, though: it's pretty sturdy.
Step 3. Place the two supplied lenses in the large
circular holes (it doesn't matter which way around they go), then fold the
cardboard around the front and back to keep them in place. You can use a bit of
tape or glue to secure them if necessary.
Step 4. Fold the main piece into shape starting with
the section shown in our photo. The circle should face inward, and is used to
hold the magnets. Again, you can use glue or tape if you like, but it's not
necessary.
Step 5. Now fold this component around the piece with
the lenses, with the centre hole facing the front. The small divider piece
slots in here to make sure each of your eyes see only the images intended for
them.
Step 6. Create an easily opened yet secure compartment
for your phone by using the two Velcro pads to fasten the flap to the top of
the headset.
Step 7. Next you need to download the Cardboard app
from Google Play. It's a large app - 74.63MB - so make sure you both have room
on your phone and that you're connected to Wi-Fi.
Step 8. Place
your phone inside the Google Cardboard headset so that the camera can be seen
through the cutout. It looks as though it won't fit because the divider is in
the way, but the Velcro should give you enough wiggle room to secure your phone
in place. Note that you might need to take off any case you might be using
first.
How to operate Google Cardboard
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 - from
Tutorial to Tour Guide, Exhibit, Windy Day, Earth, YouTube, Photo Sphere and
Street Vue.
All the apps are
cool - we particularly like Windy Day, a cute game in which you have to search
the forest for a mouse - but they are relatively limited. For example, with
Exhibit you get to look at only one item; in Google Earth you get to explore
only one corner of the world; and in Street Vue you don't get to pick your
street or where you go.
YouTube is one of the best of the bunch:
you look around left and right to see multiple video screens, then stare at one
and pull down the magnet to play it. The video will open on what looks like a
cinema screen, from which you can look down to select voice search.
