OFweek VR network news VR can be described as a very hot word, and even CCTV have recommended, but because of high prices, technical vocabulary too much, VR equipment exactly how to choose? Xiaobian inventory VR equipment to buy so can not be wrong!
The type of VR
The current market for VR glasses can be divided into two major categories: PC VR and mobile VR.
(1) PC VR is characterized by: need to connect to the PC or the host to use is often a relatively strong computing performance, display effect is good, and can walk in space. (There is a special case of the PS VR, which is connected to the PS game console and has more playable resources.)
The representative product of PC VR is HTC Vive and Oculus Rift with three cameras. You can walk in the virtual world after you take it, but there is a certain range of restrictions (for example, HTC Vive probably needs a 20m2 site).
(2) Mobile VR (also divided into mobile phone box and one machine)
Mobile phone boxes represent Samsung Gear VR and Google Cardboard. The principle is to put a lens on the phone to let you see VR. The advantage is convenience, there is a mobile phone can see; but because of the small size of the mobile phone, and the large amount of VR calculations, so serious fever, with the use of the card.
The all-in-one machine is a mobile phone, but the core components of the phone are integrated inside the VR glasses. Because of its large size, the heat dissipation is better and the performance is more stable. However, the effect of using a mobile phone box on a flagship mobile phone is similar.
(3) NOLO
This one can be understood as a combination of PC VR and mobile VR. NOLO is composed of positioning receiver, handle and a detector. After being mounted on the mobile phone box, NOLO can also enable you to walk in virtual space.
What are the points for buying VR?
Resolution
(1) Resolution of cell phone box
Factors affecting the quality of mobile phone boxes In addition to the mobile phone's own screen resolution, the most important accessory is the lens; but the major manufacturers generally claim to be using imported lenses, but the results are more general, there is not much difference, buy Choose a brand with a good rating or buy it with your personal preferences.
(2) resolution of the integrated machine
For the all-in-one, the 2K screen is an entry-level choice, so try to buy 2K or higher resolution. (2K refers to a horizontal resolution of more than 2000px, for example 2160x1200px resolution of the device has reached the 2K standard).
(3) Resolution of PC VR
The starting point is that the single eyepiece achieves 1080 x 1200px. At this time, the resolution of the binocular screen is 2160 × 1200px, which can satisfy the smooth running of most games. Of course, it should not be too high. If the resolution is too high, the image will be compressed on the lens. Sharpening effects are not worth the candle.
?delay
Delay will directly affect the VR device will play dizzy! The general delay (running frequency) can be guaranteed at 90Hz (all products will be marked with this parameter, the lower the value, the better); if the picture has a high delay rate, it will be dizzy.
Perspective (FOV)
From the perspective: refers to the field of view can be seen on the lens, the general VR device can be maintained at the viewing angle between 96 ° -120 ° can be, because of the body rotation technology, so the perspective is too large and is not necessary.
In addition, most of them support the adjustment of focal length, which means that people with slight myopia can see clearly without wearing glasses. Generally, the adjustment range is about 600 degrees, and more than 600 degrees of myopia will need to choose to wear glasses.
Wearable comfort
To say comfort, the best is PC VR, because it requires external equipment, so it is usually designed as a helmet, whether it is comfort or fit is better.
Resource issues
That is to say, we bought a VR device, but we found that there is no support for compatible games, so it's awkward. Therefore, the problem of game resources when purchasing is also very important. The average VR device will provide a certain amount of videos and games for the experience, and major manufacturers will also update resources at any time.
Another very special one: PS VR is connected to the PS game console, although the picture quality is weaker than the PC VR, but the advantage is that the PS system has enough games, so players have more choices.
?Device Configuration
The most important one of the all-in-one machines is the processor, which can be Qualcomm 820 and it is fully enough.
For the PC VR, the specific configuration of the computer is as follows: NVIDIA GTX 970 or higher on the graphics card, CPU Intel Core i5, and 4GB RAM (8GB is the best) to experience the ultimate gaming experience.
In general:
Mobile phone boxes are suitable for beginners and people who want to play anywhere, anytime;
One machine orientation is medium-level demand, and it feels low at the low end, and there is no need for people to buy high-end products.
The PC VR positioning is a high-end user, is to experience the most pure VR audio-visual effects.
