Virtual reality glasses have in common that they open exciting virtual worlds and provide a three-dimensional interactive experience, but this pleasure is expensive, and to choose the right one, several tests must be conducted, and this is what the German experts in the Commodity Testing Authority have done.
3 different concepts of virtual reality glasses
The German Goods and Products Testing Authority stated that there are 3 different concepts of virtual reality glasses;
There are glasses with a computer, others without a computer, and a combination of the two methods, and here a question arises about the appropriate type of virtual reality glasses.
The authority added that the three types are very similar in terms of the quality of virtual reality, that is, diving into the virtual world. The German authority reached this conclusion after testing five types of virtual reality glasses.
However there are a variety of advantages and disadvantages;
The stand-alone glasses provide more freedom of movement, and create no tripping hazard;
Because it can be used without connectors, and the importance of this type of glasses appears when climbing mountain valleys, or during virtual sword fights.
On the other hand, virtual reality glasses connected to computers allow better quality in terms of graphics and graphics, and more accurate motion tracking.
Since the process of tracking players is not limited to internal sensors only, but external sensors are also relied upon.
In addition to the exorbitant cost of virtual reality glasses, they require high-performance computers at a very high cost. German experts advised using a gaming computer equipped with a Display-Port and a high-performance graphics card.

Basic requirements
Among the basic requirements for enjoying virtual reality glasses is the availability of sufficient space, so that the user does not collide with the wall or the cabinet, with the need for a fast Internet connection, and the experts of the German Authority advised that there be an area of at least two meters x two meters, and an Internet connection with a speed of not less than 50 megabits / second.
Ordinary glasses can be used in the internal range of virtual reality glasses at times, but they may not fit with them at other times, and some types allow glasses owners to adjust the distance between the eye and the virtual reality lenses, but in case of doubt it is better to use contact lenses.
applications used
The fun of virtual reality is not only associated with virtual reality glasses, but also depends to a large extent on the applications used, and there are many online stores specialized in virtual reality applications;
Such as: Steam, Oculus, or Viveport, and there are many free applications, while some other applications require paying costs, and German experts confirmed that virtual reality applications can be used from different stores.
German experts expressed their admiration for virtual reality games.
Such as: Beat Saber, Half-Life Alyx, or exploration apps;
Such as: Google Earth VR (Earth VR), but the playback of 3D visual clips was disappointing;
Since it appeared relatively inconspicuously;
Because the image material was in very high resolution (8K), which is not enough resolution to play 360-degree videos in 3D.
The test results of the German authority topped the virtual reality glasses (Index) connected to the computer, and the virtual reality glasses “HTC Vive Pro 2” came in second place, while the third place went to the virtual reality glasses “Meta Quest 2”. (Quest 2), which can be used without a computer, and it also allows more freedom of movement through the wireless connection function to computers.
