DIY virtual reality glasses diagram. How to assemble a Cardboard with your own hands: drawings, dimensions

Good afternoon (evening/night optional).

Today I will tell you how to make glasses virtual reality with your own hands, no phones(Traffic!):

PREFACE

On at the moment NO official standard for VR glasses/mask and the like. About Oculus, HTC, Samsung, Sony, etc. there is no point in talking and comparing. These are just devices with different functionality +/-, some gadgets. There is no point in arguing about what VR is, everyone sees it differently.

I’ve been wanting to play with this kind of thing for a long time, but phone glasses don’t appeal to me, they’re inconvenient, heavy and there are few applications, poor synchronization with the PC, phone battery, radio delay.

In the process of working on my experiment, 2 nuances that were important to me were highlighted:

1. Head tracking.
2. Display instead of a phone.

Based on these nuances, I started building the unit.

I’ll say right away that the thing is in itself and does not pretend to be of quality; anyone can repeat the production of this helmet based on the instructions received.

COMPONENTS

For the glasses I needed the following components:

MATERIAL PART

The first thing is a warning:

All responsibility, namely independent penetration into the body of the finished product with subsequent violation of its integrity and performance, lies with the person who committed this action.

Frame:

The body will have to be assembled separately for the matrix, due to the fact that the matrix is ​​quite voluminous and a different focusing distance is required. Lens replacement required. The part that will be applied to the head and nose will be taken from this body.

Controller:

The main task is to synchronize the controller with the matrix, I knew that the controller and matrix would work, but whether I would get the required resolution is another question.

I’ll give you an excerpt from the datasheet:

My display has an aspect ratio of 16:9 and a resolution that falls within the 1920x1440 range.

The problem is that the controller has the wrong resolution and needs to be flashed.

Initially, when connecting the display, instead of a picture, I received a set of stripes. (I even thought that the display itself was covered).

But after a while (when connected to a computer) it became clear that the display was displaying something, but it was clear that it had a problem with synchronization and resolution.

When installing the firmware, I went through more than a dozen and settled on this version:

Now, when connected to a computer, the display displays information that an HDMI connector is connected and offers a resolution of 1024x600. In this case, the display actively tries to receive a signal from VGA, and the message “Connect the VGA cable” appears.

I had to scratch my head again. This controller is a direct analogue of boards with a large number connectors, for example:

This means you need to wire up buttons to your controller so that you can customize the display and switch operating modes. I have attached a diagram for the connectors, the buttons hang on the 53rd leg of the chip:

Just in case, I am attaching a diagram of the RTD2660 chip:

After flashing the firmware and switching the controller to HDMI mode. The display began to start under WIndows 7, my surprise was great when, in addition to the native, native resolution of 1024x600, I was able to set the resolution to 720p and 1080p. At 720p it works great without being distorted, but at 1080p the fonts are no longer readable, but it holds it just the same, surprise, running games at 720p is more fun than at 1024x600 (not all games support low resolutions).

Matrix:

I was already playing with glasses on my phone, the resolution was 960X540. I launched Half-life 2, Portal, but I didn’t like the fact that it was a phone and the fact that I couldn’t look around the space with my head, I rotated the mouse + delays via Wi-Fi, they just infuriated me and didn’t let me play. In general, the pixels are visible, but I still liked it.

A 7-inch 1024x600 matrix, part number 7300130906 E231732 NETRON-YFP08, was removed from the spare parts box. Based on the available matrix resolution, we can conclude that for each eye the resolution will be 512x600, which is slightly more than the phone screen resolution and, most importantly, there will be no delays.

The matrix connector has 50 pins and is fully compatible with the display controller.

To achieve maximum contrast and image richness, you will have to remove the matte film from the matrix. Since the product will be closed, there is no risk of any glare.

Finalization of the matrix is ​​carried out in 7 stages:

1. disassemble the matrix along the edge of the frame;

2. place the module on the lining (here you can tape the edges of the module to the lining so that water does not damage the part);

3. Place a damp cloth on top of the display, preferably the size of a matte film;

4. Gently soak the napkin with a small amount of water at about 25 degrees;

5. wait about 2 - 3 hours, it all depends on the quality of the coating. (the glue of matte films is sensitive to water);

6. carefully pry up the edge and slowly, without jerking, remove the matte layer;

7. check.

If you want to collect glasses on a 2K display, then I will give you a link:

For this price on Ali you can buy a ready-made device with FullHD ->

Therefore, I did not spend money on the concept and decided to use what I had for testing.

Arduino and gyroscope:

The most important part Getting the effect of presence in a game, application or video is the ability to control your head, which means we will write head tracking.

Excerpt from the official source for Arduino Leonardo:

Unlike all previous boards, the ATmega32u4 has built-in support for a USB connection, this allows you to set how Leonardo will be visible when connected to a computer, it can be a keyboard, mouse, virtual serial / COM port.

This is exactly what I need.

The simplest and most common gyroscope was chosen - GY521, which has an accelerometer on board:

1. Accelerometer ranges: ±2, ±4, ±8, ±16g
2. Gyroscope ranges: ± 250, 500, 1000, 2000 °/s
3. Voltage range: 3.3V - 5V (the module include a low drop-out voltage regulator)

Gyroscope connection:

#include #include #include #include MPU6050 mpu; int16_t ax, ay, az, gx, gy, gz; int vx, vy; void setup() ( Serial.begin(115200); Wire.begin(); mpu.initialize(); if (!mpu.testConnection()) ( while (1); ) ) void loop() ( mpu.getMotion6( &ax, &ay, &gx, &gy, &gz); vx = (gx+300)/200;

Based on the sketch, we can conclude that head tracking is essentially a gyro-mouse.

CONCEPT

It all came down to the division into stages:

1. trying on head tracking;
2. writing tracker firmware;
3. ordering the required controller for the display;
4. setting up and launching the display with the controller;
5. fitting and general assembly.

This is what debugging a head tracker with a gyroscope looked like:

Video of the head tracker in action:

Running the display with a controller:

To run the display, I need the Tridef 3D program, which allows you to run games and applications with Side by Side images, which I used as a test.

The reason for use is quite clear, these glasses will not be recognized as Oculus DK1/DK2 glasses and in order for the device to be recognized as VR glasses of at least the first revisions of the oculus, it must be completely changed software display controller, which I can’t afford yet, it will also require either partial prototyping, or creating again a concept board based on the kind of gyroscopes that are used in oculuses -

But due to the fact that I decided not to spend a lot on this project and I’m not going to make money from it either, we’ll leave that for other people. (I know who makes sets with oculus firmware based on similar glasses for smart phones, but I won’t advertise them, the post is not about them)

Frame

Having played enough with a standard body, I decided to try the matrix on it and was very disappointed, the matrix turned out to be too large for the focal length, I saw everything but did not see the whole picture, it did not add up into one.
The assembly of the body began from scratch.

Having broken off all the protruding parts, as well as the fastening of the head strap, I got the following set:

Actually, like many prototypes, I chose corrugated cardboard, as the most flexible, easily accessible material:

Testing

During testing, the glasses performed extremely well; playing at 720p resolution is a pleasure. The gyroscope works great and follows head movements, the mouse does not float along the coordinates, I passed the cable through my head behind me, 3 meters was more than enough.

Nuance:
The glasses stick out quite a lot, although the mass is not very large, you have to get used to turning your head.

Disadvantages of such a system:

1. You need a smaller matrix in order to reduce the length of the body.
2. You need high-quality lenses (for mine, I took them from magnifying glasses at the nearest print shop).

In general, for myself, as an undemanding person, it will do.

Once I’ve played enough with it all, I’ll make an 8D projector from this matrix and controller. (Keep an eye on the reviews)

Thank you for your attention and patience, I will be happy to answer your comments.

Virtual reality is amazing world, immersing yourself in which you get a lot of unusual impressions. But in order to move into the three-dimensional dimension, you need to have special glasses. They are quite expensive in the store, but it is not difficult to make them at home. You just need to know how to make virtual reality glasses with your own hands. The easiest way is to make an analogue.

What will be needed for production?

In fact, you don't need to buy any to make glasses. large number tools and materials. You just need to have:

  1. A gadget with which you will immerse yourself in the virtual world. This can be a smartphone or tablet (smartphone is preferable)

The more modern the device is, the more spectacular the game will be. The size of the phone or tablet is also not important. The only thing is that the smallest side must be equal to at least two distances between the pupils of the eyes. But you shouldn’t take too large a gadget either, since the middle of each half of the frame should fall into the center of the pupil. This parameter must be adjusted using lenses, moving them closer and further away from each other.

  1. Can't do homemade helmet for virtual reality without lenses. There should be two pairs of them. It is better to choose glass of large diameter. This is due to the fact that their minimum distortion is closer to the center. The greater the distance, the more the image is distorted. The small diameter of the glasses will not be able to cope with the difference between the pupils and the center of each half of the picture.
  2. You will need construction polyethylene 20 mm thick. It should be of medium density.
  3. In addition, you will need double-sided tape, as well as regular or vinyl film.
  4. The frame of the helmet will consist of cardboard. It should be micro-corrugated and 2 mm thick.
  5. To secure the glasses you will need a wide belt or elastic band. It is convenient to use the Velcro fastening.
  6. To make a helmet, you need drawings. To create them you will need tools for drawing and cutting materials.

All materials are inexpensive, and therefore the helmet will cost much less than a store-bought one.

Making a helmet

Before you make a virtual reality helmet with your own hands, you need to download the Cardboard smartphone application in advance, which will allow you to evaluate the quality of your future helmet.

Next, you need to start making the frame for the first pair of glasses. It is made from a sheet of foam plastic. It is recommended to adjust the lenses so that the distance between your eyes and the phone screen is minimal. To do this, the smartphone is placed on the table and the focus is adjusted using lenses. Once the required distance has been found, the holes can be cut using a centrifugal drill or a compass with a utility knife.

Next, a frame is made for the second pair of lenses. Each glass should be placed in polyethylene. With its help, a 3D effect is obtained. To achieve it, you need to choose the right focus. This can only be done by experimenting with glasses.

After this, you need to make a frame for the helmet. Here it is important to adjust the box to your anatomical features: the shape of the nose, skull, vision. The main thing is that the helmet is comfortable.

It is also necessary to consider the sound output. This is where you should choose good headphones.

The next step is the correct positioning of the phone or tablet screen.

Important! The axis of symmetry, located horizontally, must coincide with the height of the represented line between the pupils.

The screen should be approximately 4 cm from the near edge of the eyepiece. Therefore, it is necessary to decorate the top, bottom, and sides with foam plastic. It should look like a kind of box. The gadget screen is placed in it.

After everything is ready, you need to once again adjust the focus of the lenses and, if necessary, correct the location of the device.

The final stage is the production of the outer frame of the helmet, which is made of cardboard. It turns out to be a box with a lid, inside which is located mobile device. It protects the fragile foam device from damage. In addition, it is the cardboard frame that holds the bulk of the smartphone or tablet and presses it against the foam.

Now all that remains is to attach the rubber band fastening. You can attach it to the frame using double-sided tape.
You also need to make a hole for the USB cable.

The virtual reality helmet is ready! You can safely download games with a 3D effect to your device and enjoy the exciting story.

Due to the growing popularity of VR technologies, many people want to join them. Today there are many different variations and models of devices on sale, different price category. Nevertheless, some users, out of curiosity or in order to save money, are wondering how to make virtual reality glasses with their own hands from cardboard or plastic (which is more difficult)?

This option is suitable primarily for those who have a modern smartphone with a large screen and a built-in set of sensors (read more about required sensors below). According to statistics, a considerable part of the world’s population uses such devices. Thus, with insignificant monetary and certain time costs, the user can make excellent three-dimensional glasses with his own hands. We will look at what is needed for this and how all the parts are assembled below.

An interesting point is that even Google produces and distributes a simplified design made of cardboard and simple lenses, called Cardboard. Their VR glasses, even in a similar design, are available in several versions that are not difficult to replicate at home.

Moreover, the company itself provided all necessary information to the public.

Thus, there is no need to talk about the relevance of the issue under consideration.

What you need to assemble VR glasses at home

Before worrying about the materials and components of future glasses, you should make sure that your smartphone is compatible with the technology. The phone settings should ensure comfortable work with 3D films, games and other virtual reality projects.

Suitable for such purposes, for example:

  • Android 4.1 JellyBean or better
  • iOS 7 or higher
  • Windows Phone 7.0 and so on

The screen diagonal must be at least 4.5 inches for comfortable and full operation of all applications.

What sensors are needed:

  • Magnetometer, that is, a digital compass
  • Accelerometer
  • Gyroscope

The last two conditions are mandatory for most virtual applications , otherwise, the user will only be able to view . Without these two components, it is not possible to fully evaluate VR technology.

It should be noted that for self-production you will not need expensive or rare components. So now let's move on to the list necessary materials for making VR glasses with your own hands at home:

  • Cardboard. It is recommended to use the most dense and at the same time thin variations, for example corrugated cardboard. The cardboard must be in the form of a single sheet with dimensions of at least 22x56 cm and a thickness of no more than 3 mm.
  • Lenses. Most the best option will be the use of biconvex aspherical lenses with focal length 40-45 mm and 25 mm in diameter. It is recommended to use a glass option instead of plastic.
  • Magnets. You will need two magnets: a neodymium in the form of a ring and a ceramic in the form of a disk. The dimensions should be 19 mm in diameter and 3 mm in thickness. As a replacement, you can use ordinary food foil. Alternatively, you can use a full-fledged mechanical button.
  • Velcro i.e. textile fastener. This material requires two strips of approximately 20-30 mm each.
  • Rubber. The length of the elastic band should be at least 8cm, since it will be used to secure the smartphone.

In addition to materials, you will also need some tools: ruler, scissors, glue. Based on your capabilities and ingenuity, some materials and tools can be replaced with alternative options, if this does not affect functionality.

As you already understand, materials and tools alone will not be enough to manufacture, much less assemble, an entire structure. Of course, this requires a drawing or simply a template diagram for creating virtual reality glasses.

You can find a template for cutting out glasses below. It can be easily printed and then pasted onto a piece of cardboard. Since the expanded version of the glasses goes beyond the usual landscape format (and is 3 sheets of A4 format), then you will have to carefully and accurately combine all the fragments at the joints.

To download the template to your computer, you need to right-click on the picture, and then click on the item "Save Image As".

3 parts template

Below you will see 3 large pictures that will need to be printed and then glued onto cardboard so that all the joints are respected.

The finished result on cardboard

This end result, which you should get by connecting 3 parts of an A4 sheet on cardboard.

Cut out cardboard design

This is what we got after we completely cut out the cardboard according to the drawing. Carefully follow the numbers and connect all the parts correctly.

Where to get glasses lenses

In this matter, it is the lenses that are the most difficult to access component. In case the nearest stores and retail outlets If you can’t find them, you can search on the Internet.

Among the available and most likely places that may offer such a product for sale are the following:

  • Shops in the “Optics” category. Here the product is measured in dimensions - dioptre, and for glasses you will need lenses of at least +22 dioptres.
  • Stationery stores. They sell magnifying glasses here (i.e. magnifying glasses), tenfold lenses should work as an alternative.
  • Search on domestic sites and trading platforms, or at foreign online auctions.
  • Make from plastic bottle(more details in video instructions)

In the event that the lenses received by the user differ to a certain extent from the specified standard, it will be necessary to either grind the lenses themselves or make appropriate adjustments to the design of the glasses. Often the problem can be solved by including in your design a device for adjusting the distance from the smartphone to the lens.

How to make glasses without lenses

Those who imagine the option of creating VR glasses without lenses can immediately forget about it. Without special lenses, the resulting design will be no different from ordinary glasses or glass. Such a design will not bring any practical benefit, except that it can be used to create a cinema effect.

Step-by-step instructions on how to make virtual reality glasses with your own hands from cardboard

So, when the user has all the materials, tools and a printed template, then assembly can begin.

First step

  1. Paste the template onto the cardboard
  2. Cut along the contour
  3. Bend and fasten individual places

The first step is to glue the drawing onto a sheet of cardboard. The main thing is to be careful and maintain accuracy at the joints so that the dimensions are not distorted. Then all elements must be carefully cut along the contour. From the special marks on the drawing it will be clear in which places the structure needs to be bent and in which it needs to be fastened.

Second step

  1. Insert lenses into the finished structure
  2. Magnet fastener
  3. Lining cardboard with foam

Next, you need to insert lenses into the already assembled frame, and, if necessary, fix them to increase the reliability of the fastener. Then a strip of foil or magnets is glued to create something like a control button.

To increase the comfort of using the resulting device, in places of contact with the head, the surface can be covered with foam rubber or other softening material.

When we decided to write an article about how to make a virtual reality helmet with our own hands, we started collecting information. The imagination of folk craftsmen is, of course, amazing, but I don’t even really want to insert a phone into such monsters =)

Therefore, we decided to take a more civilized route and offer the option of assembling VR glasses from - accessible to everyone. What do we need?

Necessary:

  • A piece of cardboard at least 22" (55.88cm) by 8.75" (22.23cm)
  • Two strips of 3/4" (1.91 cm) wide Velcro tape
  • Two biconvex lenses (focal length 45mm)
  • Stationery knife

Optional:

  • One 3/4"(1.91 cm) neodymium ring magnet
  • One 3/4" ceramic disc magnet

Instructions
We start by downloading instructions from the official Google website for assembling a DIY helmet - instructions. In it in more detail the assembly plan is written, but... In English. So you can just click on the images below and copy them to your computer, we won't be offended.


We print these 3 images on the printer, which will become stencils for cutting out parts of the helmet. It is important to note here that the third image is a continuation of the second. They show a part that needs to be cut out entirely.


Cutting will take quite a bit of time... Be prepared for this. But what we have ahead of us is immersion in the virtual world? It's worth it! Once everything is cut out, you can start assembling. Here we need not a lot of glue, pre-prepared Velcro, lenses, deft hands and a little luck.

A short digression about magnets. They are needed to make a control button. In some VR games and videos, you can use it for control. If there is a lot of enthusiasm, then you can mess with it. But, as it seems to us, there is no particular meaning in it. There is very little chance that it will work. Not every smartphone model has a magnetic control trailer. It is much more practical to use any of the bluetooth joysticks, for example like .

Actually, assembly.


First, we fold the front part of the helmet 3 times, installing the lenses in special holders. Then we wrap this structure in a frame cut out according to Figures 2 and 3. Where to glue the Velcro that will secure the front cover with the phone inserted inside can be seen in the screenshots attached to our article.

If desired, you can attach any kind of straps to the helmet to keep the device on your head. But remember - this is cardboard! It will not withstand such loads for long. We would advise holding the helmet with your hands. After an hour or two painstaking work, in some cases seasoned with a pinch of swearing, we get a pretty good-looking device. Much nicer and more functional than those monsters that were shown at the beginning of the article.



Actually, the helmet is ready. Now all that remains is to download the Google Cardboard application, described in detail in the article on our website -. First of all, the program will ask the camera of your smartphone to read the QR code of the helmet in order to configure the phone to work with VR.


Next, you will already have full access to a variety of demos and 360 videos on YouTube, directly through the Cardboard application.
Have a successful and unforgettable immersion in the world of virtual reality, which is just beginning its journey and is aimed at great development. The portal administration is sure of this!

In case you still can’t assemble the helmet yourself or it’s simply not possible to find lenses, don’t be upset. Already Google ready Cardboard can always be purchased on Yandex.Market for 300 rubles.

Having your own virtual reality module has been the dream of many since childhood, and progress is already very close to the creation of such devices. In 2014, Google developers presented the world with a stunning invention that uses the capabilities of regular smartphones on the Android platform. Right at the conference, any participant could assemble a virtual reality helmet from cardboard and a few simple parts and appreciate the delights of three-dimensional graphics and atmospheric video with the ability to view a full 360-degree view.

Virtual reality on the cheap

Google Cardboard was not a technological breakthrough; virtual reality helmets have been around for quite some time; moreover, many are familiar with children's devices for viewing three-dimensional images. Nowadays, few people can be surprised by the ability of smartphones to navigate in space; no, the public was surprised by something else. The simplicity and accessibility of the design is what really deserved attention, and besides, the developers have now released many applications that use this device to immerse themselves in virtual reality.

The developers of Google Cardboard opened up all the technical documentation for the device, refusing to trade their invention, and manufacturers instantly picked up the idea. At the moment, there are many different models made of plastic, cardboard and even leather products. For around $20, you can purchase cardboard kits like those that were first presented at the developer conference in June 2014. Also, instructions and diagrams are available to anyone, and it will not be difficult to assemble Cardboard with your own hands.

Materials

The prices for a cardboard box are, of course, quite significant, but before you make Cardboard yourself, you should know where to find or purchase the rest of the materials. We will need:


Electronic component - a powerful smartphone

Let us now analyze all the components point by point, starting with the models suitable smartphones. Anyone can find the ones invented by the developers for Google builds DIY Cardboard drawings. The sizes of phones suitable for such versions of glasses 2.0 are limited to a width of up to 83 mm and a diagonal of up to 6 inches. For other sizes, you will have to think through your own design, selecting the distances to the lenses experimentally, or look for an option from ready-made products in the store. 3D glasses also place additional demands on the device’s screen. Remember, you won't just be looking at your phone screen from very close, but you'll be getting magnification through the lenses. Of course, the better the screen, the less discomfort. At the moment, it is possible to use smartphones based on or higher (from 4 iPhones) or Windows Phone 7.0 and higher, but initially the entire system was designed specifically for Android 4.1. Download any VR application and check your smartphone for compatibility by rotating it and watching the picture.

Housing material

It is not difficult to select cardboard for the base of our glasses; a large pizza box has suitable parameters. You can also purchase cardboard in craft stores or disassemble some ownerless box from household appliances. Cardboard that is too thick will be inconvenient to cut and bend, while thin cardboard will most likely not hold the lenses and smartphone in a rigidly fixed position on the head.

Optics

With lenses, perhaps, it will be the most difficult, but this is the most important material for 3D glasses. Google recommends using lenses for Cardboard with a focal length of 45 mm; accordingly, the sizes of the virtual reality glasses themselves on the site are designed only for lenses with this focal length. Thus, the desire to use different lenses, or perhaps a system of two or more lenses per eyepiece, will inevitably lead to a readjustment of the distance to the eyes and the screen, thus changing the entire design. If you feel confident enough, it's worth experimenting, but it's much easier to order lenses.

Fasteners

As an attachment to the head, you can use a fabric elastic band or a Velcro strap. It’s not difficult to find rubber bands for the case, and even easier to replace. After assembling the entire structure, it is only needed to hold its shape. You can simply glue the 3D glasses at all joints after adjusting the lenses with glue or tape. Two Velcro strips measuring 15x20 mm will be needed to secure the closed cover with the smartphone inserted. In the absence of one, there are many options for fixing the cardboard cover; the main thing is to make sure that the smartphone does not fall out while using 3D glasses.

Additional controls

Magnets are needed to make an optional 3D headset control button on the case, and are only suitable for smartphone models with a built-in magnetometer. When creating a helmet for testing, you should not waste effort and money searching for suitable magnets. Such a button can be attached to virtual reality glasses separately after full testing of the device or not installed at all. For long-lasting 3D glasses, you will need a neodymium magnet ring and a magnetic ceramic disc, both measuring no more than 3x20mm. You can also cut holes and operate your smartphone with your fingers.

An NFC sticker is glued to the inside of the glasses, which allows the smartphone to automatically launch the necessary applications. You can probably find it in communication shops or online stores; it is also not mandatory, and you can install it later.

Tools and safety precautions

The simplest tool you will need is:

  • Google Cardboard template. The drawings are in the article.
  • A sharp knife, a durable stationery knife will do. The cardboard needs to be cut clearly along the lines of the template, especially the grooves and holes, so scissors won’t do the job.
  • Scotch tape or glue.
  • Hard line.

Google claims that scissors are enough for the job; don’t delude yourself; thin slits and fixing grooves are much more convenient to cut with a blade.

The design is reinforced with stiffening ribs from the inside, so there is not much difference between cutting out a whole pattern from a long piece of cardboard or assembling it from 2-3 parts, connecting them with tape. When cutting with a knife, be careful not to scratch the surface of the table or floor; take a special board for this purpose, for example, a cutting board from the kitchen. Particular care must be taken when cutting out holes for lenses, so that subsequently the lenses lie in the same plane, perpendicular to the view.

Assembling the device

Assemble according to the drawings, strengthen the frame with adhesive tape and carefully monitor the location of the lenses. In a fixed position, the cardboard will firmly press the lenses so that they do not move relative to each other. Next you need to glue Velcro as fasteners along the edges of the top side and on inside covers, and also install magnets in place. At this stage, you can already try on the 3D glasses on your head to determine areas of possible skin chafing. When watching a movie for a long time, for example, these points can be very irritating, so you can additionally pad them with thin strips of foam rubber.

Is the game worth the candle?

The 3D glasses are ready, all you have to do is secure them on your head with an elastic band or strap of your choice, insert a smartphone with a 3D application and enjoy virtual reality. As for the cost of the resulting device, there are many offers of ready-made kits priced under $10. You can save money only if all the parts are on hand or within easy reach. If you order spare parts, taking into account various expenses For shipping and order fulfillment time, it turns out to be somewhat more expensive than buying the entire set. Naturally, if your dog bites the 3D glasses because you sat in virtual reality instead of feeding or walking the animal, you can easily assemble new ones using the instructions above and the remaining parts. In the meantime, you are looking for cardboard to replace the damaged one, to restore the Cardboard with your own hands, you can walk the dog and feed it.

Device capabilities

At the moment, there are already a significant number of optimized for Google Cardboard applications and several films. Paired with headphones, virtual reality glasses can easily replace a good 3D cinema, and games, according to users, despite their primitiveness, can add a strong sense of presence and atmosphere. For craftsmen and lovers of various technical tasks, it can be noted that it is possible Cardboard glasses connect to a computer to use the virtual reality module in games. This is where the truly immersive experience comes in.
