VR Cinema for Cardboard - Virtual reality cinema for Cardboard

Thanks to this application you can watch movies on your VR display. The application splits any MP4 video. The screen is divided into two halves with the same picture on both sides. It's not real 3D, but the feeling is comparable! Videos are downloaded from the memory of your gadget or from Google Disk. VR Cinema allows you to watch videos captured on your gadget’s camera. The app also has a VR camera feature that uses front camera. It's a funny effect, but I didn't appreciate it. The application has not yet been finalized and you can feel it. In future versions, the developer promises to introduce control using a magnetic ring, the ability to transfer video online and will increase the number of processed formats.

If you cannot get lenses or they are offered to you at a price higher than $3, then order right away Google ready Cardboard worth $3.2!

All you need to do is fold these 3D glasses from the disassembled state, insert your smartphone into them and you can enjoy 3D reality!

Buy Google Cardboard Can

I'll tell you right away. I don’t understand anything about this yet, and my grandchildren haven’t taught me yet. But the fact that virtual reality glasses can be made from old glasses and a shoe box was immediately captivating. He dragged me to his place for further investigation.

This project will show you how to make VR views such as Google cardboard, but optimized for tablets. Apart from the tablet, the cost is very low. He uses two pairs of reading glasses from the dollar store (Dollar Tree), a plastic shoe box, and a pair of inexpensive prism lenses costing about $7. The result is a very efficient device thanks to high resolution display and a larger field of view of the smartphone.

Step 1: Some Background Information

I created this device in order to engage students in the classroom using VR technology for their education. Since I am an educator in Salinas, California, I am naming this Salinas VR viewer.

Google's Cardboard was inspired by this viewer, but it was made to address several major shortcomings of trying to force the viewer to a larger screen than a smartphone. It would seem that all that is needed is to scale to the view size, but there are several problems with this approach.

One of the main problems is that, like cardboard, such a viewer will only use a simple pair of convex lenses to view the display. However, this may not be effective because large size display means that images cannot be placed (optically) directly in front of each eye. If these have not been corrected, then the person should be able to move each eye towards the direction of the ears. My viewer solves this problem by using an inexpensive prism lens, shifting the image so that it is optically directly in front of the viewer's eyes.

Another problem with using simple round convex lenses is that they are simply too primitive to allow for a VR experience. Such lenses have very limited area to widen the viewing area is that the eyes must be placed very close to the lens and thereby limit any eye movements. This kind of restriction on how we move our eyes is not natural. It's hard to see how much fidelity a VR system can have if it forces a person to hold themselves rigidly, looking straight ahead in an effort to keep the image in focus. People should be allowed to move their eye and still see VR images. Fortunately, some lenses have evolved to be as optimal as possible for people to use, i.e. reading glasses. These glasses allow for a wide field of view (fov), and a very large viewing area. These glasses are also extremely inexpensive.

Step 2: Equipment:

1 scribe [I thought for a long time what this means, probably in Russian - scribe:) ]: made by you.

Made with #90 wire nails, and some plastic folded and stitched. This allows the scribe to mark and cut very beautifully with either a utility knife or sharp scissors.

2 Pairs 3.25 Magnification Wide Frame Reading Glasses: Dollar Tree

Price: 2.00 Dollars. This is quite profitable. Other stores like pharmacies have them hard to find and sell a lot more (+10.00 per pair).

1 pair 1.5 Prism Wedge lens pair: Berezin stereo photography products http://www.berezin.com/3d

Price $7.95 per pair.

1 Plastic Box: Amazon: Whitmor 6362-2691-4 clear vu collection of women's shoe box by Whitmor

Price: $11.99 You need 1 window, but you get a set of 4. You can make at least 6 viewers through 3 boxes, and use another box for other plastic parts other than the body (plastic body)

1 roll of glue dots (high strength):

Price: about 5 dollars. Without this amazing glue, it would be impossible for the viewer. Please note that you are not using it from the video. You use the scribe (see above) to pick up the point and place it where needed.

3 templates: PDF files that need to be printed.

Cut it out and stick it on the plastic, then you can scribe the spare part you need. They are in color, but you can use the color code on the screen and still have them printed in black and white.

Step 3: Cut and connect the reading glasses.

Using a Dremel with a cutting blade (diamond works great), cut off the handles and nose of both pairs of glasses. Then apply glue in dots along the edge of the glass and on the bridge of the nose and stick together. Ready!

Step 4: Scribe, cut, then staple the side supports.

Tape plastic through the template supports, and scribe using a ruler. Then we cut out the supports and fasten them along the marked line, then fold them as shown in the picture. Repeat for the second support.

Step 5: Cut out the prism supports, place in the sliding metal, attach the side supports.

Cut out the prism supports, staple them along the marked line, then slide two of them onto the metal strip, and fold the sides down on both ends so that it fits into the glasses support. Metal strips from sliding onto a file folder.

Step 6: Pour hot glue into the side supports to make them rigid.

Apply glue in dots on the corners of the glass on both sides and place the glass in the side supports. Then fill the side supports with hot glue to make them rigid.

Step 7: making the body. Cut and scribe a plastic shoe box.

Cut into a shoebox using a template. In a shoebox it's long enough to cut out each end to get two sleeves.

Step 8: Cut and bend the metal strip, place it in the casing and seal the sides.

Again using the file folder metal strips, cut them to size using the templates, bend them, and place them inside the bottom of the casing. Fold back the casing and secure the metal strips in place.

Step 9: Put the latches on the top of the case.

You can use any type of schnapps or even staples to finish the frame. The ones I used are plastic latches that cost about $4 for 60 will fit, but you need special pliers that sell for about $20.00 (Walmart). Metal latches work well and you don't need an expensive tool to use them.

Step 10: Attaching the prism lens to the prism supports.

Remove the metal strip from the glass and apply glue in dots on the prismatic supports. Make sure the prism lens position is from the thin side towards the nose, hold the two prism lenses together and push them onto the supports. Place the metal strip on the glasses there.

Step 11: Make a back support, and staple and glue to the body.

Many of you have heard about Google Cardboard! A long time ago we wrote on our website about the exit of this device! Now every owner Android smartphone can buy it and download a bunch of games and applications under Google Cardboard on the official website!

Buying it is of course all great. But what about making a virtual reality headset yourself? And so, we will now tell you how to do this.

1. Take everything you need

What do we need to do this miracle? So, you need to get: cardboard (you can buy it at a creative supply store), lenses, magnets, as well as Velcro and elastic.

2. Download the drawings

In the future, if our readers want and are active in the comments, we will write instructions in Russian.

Non-standard solutions

When you make your virtual reality glasses, don't forget that you can get creative with your ideas. Decorate your Cardboard beautifully. The image above shows a very nice Google Cardboard called POWIS VIEWR. This model will cost you $30. Now it’s about 2,000 rubles. It may not seem expensive, but making something original yourself is much cooler!

Camera Jump

If you are very pleased with these gadgets and you have extra money, then you can get a gadget like Jump. What is it? This is a peculiar design of 16 chambers, it all looks like a ring.

Turning your smartphone into excellent quality virtual reality glasses is not at all difficult. To do this, you don’t need to buy any expensive devices; it’s enough to show ingenuity using improvised means. We have compiled for you small guide: “How to make virtual reality glasses.” For virtual reality glasses, a touchscreen phone running Android 4.1 and higher, iOS 7 and higher, and Windows Phone 7.0 and higher.

We make our own virtual reality glasses.

To make virtual reality glasses you will need: cardboard, scissors, a utility knife, paper glue, a printer, 2 flat-convex lenses, Velcro (which is used in clothing), a smartphone.

It is very important that the display is at least 4.5 inches. The phone must be equipped with an accelerometer, magnetometer and gyroscope. In the absence of a gyroscope and accelerometer, virtual reality cannot be assessed.

Next you will need a sheet of cardboard. It is advisable to take micro-corrugated cardboard, which is often used to make various containers (pizza packaging is ideal). You also need a template for cutting out glasses, printed on A4 sheet, and you will need three sheets. This template can be easily found on the Internet.

You can download the template on the official website, at the bottom of the page you will find the Built It Yourself block and click the Download Instructions: Cardboard button

Or the Russian version: Cardboard

You also need two lenses, namely aspherical lenses with a diameter of 25 mm with a focal length of 45 mm. These lenses can be purchased at an optical store or ordered online.
Note that the larger the focal length, the further the phone should be removed from the lens. If you don’t know the focal length, you will have to create a device that adjusts the distance of the lens from the smartphone.

Among other things, you need magnets. One round magnet is inserted inside the structure, and the other is attached outside. The second magnet is held in place by magnetic field first magnet. When interacting with the virtual world, the magnet must be moved downwards with your finger and then returned back.
Also, to create VR glasses you will need Velcro for clothing. Such Velcro is sold in any fabric store at a cheap price. Finally, you will need a utility knife and double-sided tape.

Now you need to print the template and glue it to the cardboard. Then the parts are cut out and the necessary cuts are made. Then Velcro is attached to the left and right side so that the structure does not move apart. It is recommended to cover glasses with foam rubber in places of contact with the eyes.
DIY virtual reality glasses made from recycled cardboard:

As we can see, making VR glasses yourself is absolutely not difficult. The main thing here is to have all the necessary details and follow the steps consistently. You can also buy virtual reality glasses for a small amount on Amazon, Ebay or Aliexpressand assemble them yourself.

Collecting virtual points reality cardboard:

This video tutorial will show you how to make cardboard 3D virtual reality glasses. To do this we need a phone, two lenses, a pen, a ruler and carton(thick cardboard). It is recommended to use lenses 5-7x, diameter 25 mm. The article consists of two parts. The first contains the basic steps for creating glasses, the second contains recommendations for improving the product and a description of applications for 3D games.

Buy ready-made cardboard glasses you can in this Chinese store.

From cardboard you need to cut out all the parts that will be needed to create the glasses. To do this, it is very convenient to use the diagram, which you can download from the link. It will make everything much easier to do. You can download this drawing for printing on a printer.

Now, according to this diagram, you need to draw out all the details on cardboard and cut them out using scissors. Next you need to collect it all, which is, in principle, not difficult to do. In all places where there are bends, you need to bend the cardboard and connect everything using hot glue. Next you need to insert two lenses.

If you made the hole a little smaller than the lenses themselves, then you can simply place them very tightly and they will not fall out, but just in case better a couple drops of hot glue.

Now we need to download an application called cardboard to our phone. There's a lot in it different games for 3D glasses and videos. You can download the demo version from the Play Store.

Let's finish the 3D glasses. We insert the cardboard with lenses and we are all ready!

Go to the cardboard program. There are two sections here. There are many different games and videos here. We launch the one we like and insert it into our 3D glasses and enjoy virtual reality.

Since the phone has a built-in accelerometer, we can move our heads and the picture will also move.

There are many applications for these 3D glasses on the play market. Make these glasses or buy ready-made ones. In general, this cannot be explained, it’s very cool! Until you try it yourself, you won’t understand what it all looks like.

How to make a reality simulator for a personal computer

Next, we will show you how to make a reality simulator for a personal computer, these are virtual reality glasses like the Oculus Rift. To do this, we need straight hands and a well-functioning head and motivation to create homemade products. If you do not have any of these qualities, but have money, then it is better to immediately buy ready-made virtual glasses.

We will need a virtual reality helmet, which you could make using the video tutorial above. The current version adds larger lenses, head mounts, and Velcro to help the phone hold better. In general, this craft is assembled more carefully.

Where can I find lenses? You can take from the magnifying glass which contains two lenses that are perfect for these virtual glasses.

We will need a more powerful computer and a telephone with good characteristics so that all programs work stably and do not freeze.

You need to download a program called droidpad to your computer or phone. This application will help us use our phone as a virtual joystick. Namely, use the phone’s accelerometer itself. This application supports two types of connecting your computer to your phone: using USB and WiFi. We don't need it using usbi, because the phone will be inserted into the virtual glasses. Therefore, we will use the wi-fi method. It is desirable that the Internet speed be good and stable.

Now we have the most difficult work ahead of us. We need to calibrate the accelerometer of the iPod phone to our computer. After installing this program, the phone will be used by default as a virtual phone in games. Certainly not all games will be supported. Instructions for calibrating a phone with a computer are available on the 4PDA website.

After we have calibrated according to the phone instructions for the computer, you can go into any game and test your magic glasses. The mechanism of this application is that using the phone's accelerometer, when you turn it, the screen rotates. It turns out to be a replacement for a computer mouse. Additionally, we need a program called cardboard. This program is needed to make the phone screen split in half. There is a special function, be sure to find it and configure it correctly so that everything works for you. Check that the phone screen is correctly divided not only on the desktop, but also in other programs.

Finally, download the latest program called Splashtop. This is a program so that we can view the computer screen through the phone. How to set up the program, instructions are also available on the 4PDA website.

After we have downloaded the program to the computer and phone, we need to launch the droidpad program to control the accelerometer, the cardboard program to divide the screen in half. These two programs must be running in the background. You need to open the Splashtop program and check if everything works. Launch the game on your computer and enjoy.

There is one caveat - the higher the pixel density on the phone, the clearer the picture will be. Besides games, of course, you can watch movies.

Everything voluminous is becoming fashionable, and many people want to have it in their home for creativity.
