What are things inside a VR Headset?

Every company has set up different features and functions for its products. With time, they upgrade the product, add the latest features, and improve the product capabilities. So the average manufacturing cost is around 300 to 500 USD. Besides, the price factor if we actively look into the components of the product, then we figure out the major components are:

  • Body 
  • Lens
  • Phone holder 

How to make a cardboard VR headset?

Most VR headsets are made of plastic by corporate manufacturing companies. They used lightweight plastic and were covered with a cushion, durable, and good-looking design.

There are a few components that are necessary for a homemade project.

  1. Google cardboard (shoebox)
  2. X-Acto Knife (Scissors/cutter)
  3. Glue stick
  4. Instant dry epoxy
  5. Clear plastic bottle made of Polyethylene Terephthalate.
  6. Syringe with needle
  7. Velcro or rubber band
  8. Smartphone (iOS/Android)

Step 1 

Firstly, cut out the shoebox using scissors according to your phone height and width. The screen size and diagonal vary from brand to brand. So before cutting the cardboard, measure the length and width of your phone. 

And cut out two rectangular pieces from the cardboard box. Make two circles for eye positioning, cut them out, and attach them into two rectangular pieces with glue. Then cut a small trapezoid shape from the middle part under your nose.

Step 2:

Cut another piece according to your smartphone height, but keep your cardboard’s width a few inches longer than your phone. It will ensure a little distance between your eye and your smartphone. The standard width measurement is about 11 centimetres or 7 inches. Cut a semicircle from the pieces. And cut another semicircle for your nose holder.

Now we need two identical rectangles, and the measurement would be 7 inches by 4 inches. Then we add those two lower portions with glue.

Step 3:

We will now keep some distance from the front piece to 1st piece that we earlier to create space for the smartphone holders. And you may want to add some extra parts in the middle of the box that will separate your eyes while watching and create a 3D effect.

Step 4:

According to the measurements, we will stick to the front of the box. Before adhering to it, we will make a camera hole for the position of the camera. Finally, we attach the top, and our cardboard VR set is ready to use. But when an object is coming close to your eyes, then. 

What about the lens

The lenses are needed when we want to see our mobile close to our eyes. So an exciting fact, when we look at things, usually, our focus on the object, when light rays come from the infinity. We can easily see something, but if the item is coming close to your eyes, you need to bend your lenses to observe the object closely. 

If the object again comes to you, and eventually you lose the focus and images seem to be blurry. When our eyes try to focus on something up close and draw a picture of it right behind your retina, we ensure this problem will never occur again. We use lenses in VR headsets for consistent focusing.


How to make VR lenses at home?

Find the empty bottle, make a circle 20 mm in diameter, and cut circular pieces from the bottle. Cut out four pieces like this because you will join two elements to create a single biconvex lens. So make two biconvex lenses.

Carefully seal all sides of the biconvex-shaped plastic frame you have joined using instant dry epoxy. And the biconvex shape filled up with clear water. To make sure to remove all the bubbles in it. Lastly filled it again and sealed the hole.

Dry it for a few moments, then test your lens on a small letter that can magnify things. And repeat that procedure for the second lens; if you build that successfully, congratulations! You are on the way to build up your own Google cardboard.

How to fix and testing your lenses with a Google cardboard box?

Now you have a pair of lenses and cardboard that we make earlier. Place that lens on the slot of eyes positioning that remains empty, and testing your iPhone or Android which one you have. Download the VR apps and load them on your phone. Now place it inside the VR headset and view it.

Why do most VR games have bad graphics when normal games are being played in VR by YouTubers? what is the main difference between them?

Most VR games have poor graphics is a bit exaggerated, although there are many games Recall or Archangel that have excellent graphics. But it is true that in general, the graphics of VR games are inferior to any standard desktop game.

Standard games have to render one frame at 25 FPS; VR games have to render two frames at 90 FPS. Definitely, there is a much higher requirement that’s why it is impossible to reach the same level of graphics fidelity.

Frames drops in standard games are not a big issue, frame drops in VR games mean is motion sickness for players. Since VR is still not mainstream, A studios are not making VR games. So most of the games are made by indie studios that have smaller budgets and so can afford only worse graphics.
