(1)PC VR is characterized by its strong computing performance and good display effect, and it needs to be connected to a PC or a host computer for use, so it can walk in space. (a special case is PS VR, which connects PS game consoles and has more resources to play. )
The representative products of PC VR are HTC Vive and Oculus Rift. You can walk in the virtual world with it, but there are certain restrictions (for example, HTC Vive needs about 20 square meters of space).
(2) Mobile VR (divided into mobile phone box and all-in-one machine)
Representative products of mobile phone boxes are Samsung Gear VR and Google Cardboard. The principle is to put a lens on your mobile phone to let you watch VR. The advantage is that it is convenient and can be seen with a mobile phone; However, due to the small size of the mobile phone, the VR operation is large, and the fever is serious, so it is stuck when used.
The all-in-one machine is a mobile phone, but the core components of this mobile phone are integrated inside VR glasses. Because of its large size, better heat dissipation and stable performance, the effect is similar to that of the mobile phone box used in the flagship mobile phone.
(3)NOLO
This can be understood as the combination of PC VR and mobile VR. NOLO consists of a positioning receiver, a handle and a detector. After being installed on the mobile phone box, it can also realize the ability of walking in virtual space.
What are the highlights of buying VR?
resolution ratio
(1) mobile phone box resolution
In addition to the screen resolution of the mobile phone itself, the lens is the most important accessory that affects the quality of the mobile phone box. However, major manufacturers generally claim to use imported lenses, but the effect is relatively general and there is not much difference. When buying, you can choose a good brand or buy according to your personal preference.
(2) Resolution of all-in-one machine
For the all-in-one machine, the 2K screen is an entry-level choice. Try to buy 2K or higher resolution. (2K means that the horizontal resolution is above 2000px, for example, the equipment with the resolution of 2 160 x 1200px meets the 2K standard).
(3) Resolution of computer virtual reality
The starting point is that the monocular reaches 1080 x 1200px, and the binocular screen resolution is 2 160x 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 and sharpened on the lens, which is not worth the loss.
stay
Delay will directly affect whether playing VR equipment will make you dizzy! Generally, the delay (working frequency) can be guaranteed at 90Hz (all products will be marked with this parameter, and the lower the value, the better); If the picture delay rate is high, you will get dizzy.
Viewing angle (FOV)
Angle of view: refers to the field of view that can be seen on the lens. Generally, the viewing angle of VR equipment can be kept between 96 and120. Because of the somatosensory rotation technology, there is no need for a large viewing angle.
In addition, most people support adjusting the focal length, which means that people with mild myopia can see clearly without glasses. The general adjustment range is about 600 degrees. If it is myopia above 600 degrees, you should wear glasses.
Wear comfort
When it comes to comfort, the best is PC VR, because it needs external equipment, so it is usually designed as a helmet, which is better in comfort and fit.
PC-side VR is: HTC vive and Oculus are better.
Others belong to all-in-one machines or mobile phones +VR devices. If possible, I personally think that HTC vive equipment is outstanding in all aspects.
