You have tried virtual reality and now you’re wondering how the technology works?
Let’s have a look at how strange looking goggles can take you to a different world.
A virtual reality headset makes you think you are at a different place or even in a different world. For you, this feels very real.
But it’s not.
Therefore virtual reality is a “reality that is not real”.
However, how can such a small object make you think you’re somewhere else?

The answer is: Because of screens. A virtual reality headset is a bit like a diving mask, except that there are two small screens instead of the lenses. You already know that screens captivate you. When you watch a movie on a cinema screen, you get so excited about the story that you forget everything else around you.
With virtual reality, this effect is even stronger. Once you put the googles on, you only see the screens. The real world is completely out of view. This makes you block it out pretty quickly.
in-built sensors record your head movement
How does a virtual reality headset know where you are looking?
Not only are the screens very close to your eyes. They also react to the way you move your head.
Imagine the little screens in the virtual reality headset show you an underwater world. Then you’ll see the water surface when you look up. And the bottom of the sea when you look down — just like in real life.
This works because somewhere inside your headset there is a little sensor that “feels” in which position the headset is.
What kind of virtual reality headsets are there?
Not every virtual reality headset is the same. The most important difference is the following:
Some headsets come in one piece,
Others consist of a smartphone and a so-called cardboard headset.
- The ready-made version
In the first form of headsets, the screens are fixed inside the headset and there is no way to take them out. Usually these headsets are attached to a computer or belong to a console.
They also come with some sort of controllers which you can use to walk around or play VR games. Since these headsets offer you more possibilities, they usually are more expensive.
- The Do-it-yourself version
The other form of headsets is a less expensive way to experience virtual reality.
As a downside, they often don’t have controllers so you rather observe the virtual world than interact with it. But before you can do that, you have to assemble your headset: from a so-called cardboard and a smartphone. A cardboard is basically a virtual reality headset without a screen inside. This is where the smartphone comes in: it has a screen.
It usually also has a position sensor to tell if you’re holding it upside down or not (however, some smartphones don’t; these are not fit for VR). This means a smartphone and a cardboard together make a functioning virtual reality headset.
Of course, this doesn’t work for anything. You cannot just read your text messages in virtual reality by putting your smartphone into a headset. All you will get is a blurry mess.
Instead, you need to open something on your phone that has been specially designed for virtual reality — for example a 360° video on Youtube or a VR app. Additionally, you will need to go to virtual reality mode before putting the smartphone into your cardboard. There usually is a small headset symbol to activate the VR mode. Then the smartphone screen will split. Instead of one big screen you get one little screen for each eye. Like this:
