Virtual Reality， Also known as virtual reality, or VR for short, this emerging thing has spread all over the world in just one or two years, and various VR devices have sprung up in people's vision, Oculus Rift、 HTC Vive 、 PlayStation VR Wait a minute. This kind of equipment belongs to high-end equipment, which needs to be used with powerful computers or game consoles. Another type is Gear VR and Google Cardboard, which just need to put your mobile phone into it for use, and the same is true for the author's Xiaomi VR.
VR looks like VR
Xiaomi VR, as its name implies, is a VR device, which is similar to most of today's products of the same type in appearance. The main body uses milk white as the color matching, which is very clean. But the white shell has a strong sense of plastic, and the traces of each piece of plastic on the splicing are slightly obvious.

Xiaomi VR claims to be able to adapt to people with myopia of 200 to 600 degrees, and this small gear is the principle of realizing this function, but this principle is also very simple. The module supporting the mobile phone is pushed out by rotating this gear, that is, the deeper your myopia, the more you need to push the mobile phone screen closer to your eyes, This is a little bit like a smart method, which is very effective.

All the parts in contact with the human body are made of "island velvet". The name sounds very tall, and feels good with FEEL, but the appearance is ordinary. Some parts have fuzzing, leading to a feeling of cheap.
The strap of Xiaomi VR can be expanded and contracted through the round button at the back to adapt to children's shoes with different head sizes.
Wear for one hour
Since the inner lens is exposed for a long time, it needs to be cleaned frequently during normal use, otherwise a pile of dust will fly in and stick to it from time to time. When Xiaomi VR is worn on the head, its light weight and comfortable "island velvet" make the overall wearing experience OK, The buttons on the top left of VR are solid, and the press feedback and key schedule are good. The author has been experiencing it for a whole hour without interruption. To be sure, Xiaomi VR will not bring me any sense of oppression and dizziness. In the whole 3600 seconds, there is no discomfort at all. It is that the mobile phone used with it is slightly heavier, causing it to slide from time to time.
After wearing Xiaomi VR, the sealing is very good. Except for a tiny gap at the bottom, there is no light leakage in other parts. There are cooling holes on both sides of the VR device, and even if it is used for a long time, there is no fogging of the lens. Another advantage is that the top of the head wear is hollow design, which will not affect the user's hair style after wearing. For handsome people: extra points.
The minor complaint is that this strap can not be fixed on my head, and the damping at the connection between the strap and the VR body is slightly lacking.
Critical content
In the "Xiaomi VR" app, you can find all kinds of content for you to amuse yourself, including VR videos that allow you to participate in live concerts, ordinary movies simulated in theaters, scary first person horror videos and all kinds of extreme sports videos. In addition to Xiaomi's own content, you can also download Youku, iQiyi VR platforms such as WeWhale are highly playable, enough for users to play for several hours.
There are still a lot of entertainment content available, but it is a little single. Sports, terror and beauty are the abbreviations of the entire content library. However, as a small member of the ecological chain, it is good to be able to do so at the beginning.
Subjective feeling
To measure the quality of a VR product, the most important thing is immersion, whether it can bring you a sense of immersiveness and whether you can fully immerse yourself in the virtual world. During the experience of Xiaomi VR, I can only say that I am only half immersed in the world, and the Xiaomi 5s Plus is used together with it. It is equipped with a 5.7 inch 1080p screen, 386ppi, and the average DeltaE is 3.2. The overall use is OK, but the 386 ppi is somewhat low for playing VR.
First, let's talk about the actual experience. The author's myopia is nearly 400 degrees. Using the scroll wheel on Xiaomi VR, I can easily adjust it to a position suitable for me. I can play happily without wearing glasses. This is very commendable. Insert the 5s Plus into the VR device, connect a pair of earphones conveniently, fix the buckle, and then put on the headwear. Xiaomi VR has a distance sensor inside, when it detects an object in front, the VR software on the mobile phone will automatically activate, and you can play happily at this time, Xiaomi VR is equipped with Bosch's 6-axis motion sensor with a 1600Hz refresh rate. The whole experience process is just like the official website promotion - low latency, no jam.
Since it is VR, the first thing to experience is VR content. The author downloaded several apps in the app store, which contain a lot of content, mainly including extreme sports from the first person perspective, the temptation to enjoy various beauties in the first person, and various creative VR videos... Most apps are different in content. When watching VR videos of extreme sports, the sense of substitution is quite strong. It is very fresh to use the first person perspective in various scenes. When you fall from a roller coaster, or a beautiful lady lures you around, There will be a kind of FEELING that has a fast heartbeat and seems to be immersive. In addition, there are many kinds of content in the Xiaomi VR application, and all kinds of VR videos will make you love it in a short time.

The quality of VR content is excellent, which is a big bonus. But when watching ordinary movie content, the experience is not so good, because its presentation form is relatively ordinary, that is, put a giant screen in front of you, and then use animation to create some virtual seats around you, but it doesn't feel like sitting in a real cinema, If you watch ordinary video content with Xiaomi VR for a long time, you will feel a little uncomfortable.
Most games require a handle. Xiaomi's handle is equipped with a 9-axis sensor. During use, the touchpad above the handle can serve multiple functions - sliding and clicking. The entire touchpad can be pressed. The two buttons below are the return button and the confirmation button. If it is too troublesome to hold the handle, You can also only use the button on the top left of your head. In most cases, this button can complete most operations. It can be used as a controller in somatosensory games, and has high playability. However, there are few somatosensory games, or the overall number of games is relatively small. Most of them are leisure oriented, which does not attract me to spend too much time on them. In general, it is OK to have a drink when I am free, but compared with VR video entertainment content, I prefer the latter to kill time.
As the title of the article shows, there is only half of the immersion after experiencing, and the factor that restricts my full immersion is that the number of pixels per inch is too small. In short, The ppi is too low. When I open the video, music and enter the virtual world, what brings me back to reality is that I can see every pixel clearly, and it is very difficult not to pay attention to it. Of course, this is not to blame Xiaomi VR, but the problem of the mobile phone screen itself. At present, this device only supports several Xiaomi phones, And all of them are 1080p resolution screens.
objective evaluation
It seems that Xiaomi can be seen wherever there is a market in any field, but it is undeniable that no matter which field they enter, they will not do too badly, and the same is true for Xiaomi VR. Its excellence lies in the combination of experience one hundred and ninety-nine From the price of RMB, it can be said that it is very good to achieve this level. The simple design, comfortable wearing experience and acceptable content make Xiaomi VR very competitive.
However, there are still some shortcomings. Xiaomi VR only supports Xiaomi VR applications. In short, it has very big limitations. All content and game platforms need to be settled in Xiaomi VR applications before you can enjoy them. At present, the number is not very large. In addition, Xiaomi VR only supports Xiaomi 5, 5s The 5s Plus and Xiaomi Note 2 have 1080p resolution, and the low ppi results in the poor viewing effect. VR applications occasionally crash or fail to open, but this is only a few cases, not serious.
Fortunately, Xiaomi VR can maintain its value. It doesn't need to update its internal components. It only needs new mobile phones to be compatible with it in the future. I believe that in the near future, Xiaomi will definitely launch mobile phones with higher resolution screens, and its content library will certainly be increasingly improved to provide consumers with more entertainment methods. Of course, It would be great if it could be compatible with other mobile phones.
