When it comes to virtual reality glasses, what everyone immediately thinks of is the Oculus Rift that was acquired by Facebook. But the Oculus Rift is not only expensive, but also not available. As a silkworm that loves digital products, what if you want a virtual reality glasses that can play virtual reality games and watch 3D movies? It seems that I can only resort to the Cardboard (Chinese name: cardboard) released by Google at the I/O conference. Once I hear the name, I know how much it is.

To put it bluntly, Cardboard is a VR (virtual reality) glasses made of cardboard, a rubber band, two lenses, two Velcro, an NFC sticker and two magnets to assemble a crepe version of the glasses. The core thing in it is actually two lenses. What do you need for a new cardboard based on the original Google? Answer: Two lenses, one cardboard, and wide tape, the cost does not exceed 15 yuan. The glasses are currently priced at $19.95 in DODOcase. According to the Cardboard drawings released by Google on the Internet, DIY such a Cardboar can save a lot of money, hahaha!

Tools/raw materials

This self-made method is simplified according to the official google modification, some of the accessories have been omitted, only for the experience of virtual reality glasses.

Lenticular lens: A pair of 2.5cm focal lengths of 4cm. I bought on a treasure is the teaching of a diameter of 3cm focal length 5cm magnifying glass 6 yuan a pair can be used.

Cardboard: Go to your home or community supermarket to find discarded cardboard boxes or corrugated paper. This does not cost money. It is roughly 1-2mm thick.

Wide tape: Transparent wide tape for daily use, do not go to the supermarket to spend 2 yuan to buy one.

Then go to a treasure order double lens or offline purchase, the price is generally about 3 yuan, and some profiteers sell forty or fifty absolutely do not buy. Wait until the lens is in hand and you can start working.

Print the downloaded drawing file. It should be noted here that the original google drawings are designed according to Google's Nexus5 mobile phone, and naturally do not necessarily adapt to the size of domestic mobile phones. Choose a drawing that fits your phone's size. You can also adjust the magnification of the enlargement or reduction according to the size of the phone. Remember! ! !

Paste the printed drawings on the cardboard with glue. After the glue is dry, cut it with a utility knife. Patifully use the knife to dig according to the drawings. After all the sheets have been cut, pay attention to the above labels and stick the same labels together.

Assembled together according to the instructions on the drawing, the core part of the glasses is the lens, carefully installed. Some places will not be fixed and need to be fixed with glue and wide tape.

Written at the end

The computer that finished the glasses is almost the same. First, the APP (Google_Cardboard_v1_0.apk) is installed on the mobile phone. There is nothing to say here, and it is no different from the general application software installation. However, it should be noted that if your app is not directly downloaded via GooglePlay (for example, downloaded from the network disk), then you need to add an OBB (com.google.samples.apps.cardboarddemo) file (also available on the network disk). Download) Copy into the SD card Android/obb folder (please keep the directory structure), if there is no obb folder, please create new, otherwise the software can not start normally.

Cardboard is an experience package with many representative VR demos, such as Google Earth, travel navigation, scene animation, etc. In fact, here are the various applications that VR may have in real life. One of the things that impressed Xiaobian was the Google Earth. This app has been used by many people, but a big change in the Cardboard is that it can automatically adjust the angle of view following the rotation of the user's head, for example, you look up Show the sky, show the ground when you look down, in short, this feeling is as real as you go to that place. Not to mention the 3D effect, the dual lens itself is built for 3D display, plus the default "3D scene" (a new 3D style of Google Earth), the whole effect is indeed different.

This is a Google Street View demo, the speed is very strong, but it is easy to get dizzy after watching for a long time.
