Important terms and concepts when purchasing a VR headset
What should you pay attention to when buying a VR headset? There are so many terms that tell you something about the quality of a headset, but if you are not at home in the technological world, it can quickly make you dizzy. That is why we have drawn up a glossary for you in which all technical terms that describe a Virtual Reality headset are briefly and concisely explained.
For example, the resolution of a VR headset says something about the number of pixels that can be displayed. This is usually shown as width x height (eg. 1080x1200). The higher this resolution, the sharper the image. Note that with VR glasses the image is often displayed on two screens (one for each eye).
The type of screen, also called display, is important for your viewing experience. In general, three types of screens are used: OLED, (super) AMOLED and (dual) LCD. One is not so much better than the other, but they do have different properties. The first in this list, and perhaps the longest on the market, is LCD. By using color efficiently, it consumes the least energy. The disadvantage is that the black colors can appear as dark gray. OLED, on the other hand, is 'off' in black light. This makes everything that is black look really black. Last in the list is AMOLED. The advantage is that it has a faster refresh rate, which makes the screen response time run smoother. But this also ensures that he uses more energy.
As mentioned with AMOLED, the refresh rate (or refresh rate) says something about the number of times the image is 'refreshed'. This is measured in Hz. In general, the higher the number of Hz, the smoother the picture. The combination of refresh rate and frames per second plays a major role in so-called 'motion sickness'.
Field of view
The field of view, also called field of view (FoV), shows how far you can see next to and above you without turning your head. This is always indicated in a number of degrees (º) and can sometimes be referred to as horizontal (left and right) and vertical (top and bottom). So you would think; 'the higher the better', but this must be in balance with the weight and size of the headset. The sweet spot on most high-end models is around 110º.
In addition to all the hardware facts, weight also plays a role. After all, you have to be able to keep the headset on for a longer period of time while gaming or watching a movie. In general it applies; the lighter, the more comfortable, but keep in mind that the hardware in the headset plays a part in the weight. For example, a Google Cardbox is many times lighter than a Samsung Oddysey, simply because the cardbox contains no hardware and consists for the most part of cardboard.
VR is generally offered on three platforms; mobile, PC and via console. The platform on which you play says something about the range of games and apps. For example, a mobile platform depends on apps that you can download on your mobile and the console depends on the games that have been released specifically for it. For a console, this can have the advantage (or disadvantage) that exclusive games are released, which you can only play with a Playstation VR for example. The PC currently has the largest library of games with SteamVR.
