Hello everyone, I am An Di. Recently, we received a mobile VR headset from the domestic fireworks workshop. The first generation of this is the hand-held machine that was sent to the media. The consumer version is also available now. 　　
Before you get started, let's do your homework in this area. The reason why I specially gave it a review, is because the domestic mobile VR headset, most of the products are done on the pure optical box, which is the vr box that we often say in the player's mouth, except for the optical, the other basic is almost the same For example, pitch adjustment, object distance adjustment, and compatibility with various sizes, so we often see products that use this concept of gimmicks.
Then many people began to ask questions. What kind of vr box experience do you think? It is not just a plastic shell. It is too big compared with the mainstream PC head. In fact, I want to understand the gap between the two. How many, we look at the principle, all PC head display (without spatial positioning) are almost equipped with a standard 1000hz sampling gyroscope, the screen depends on the host's powerful graphics output, so you get a very real picture output, The only thing that is different from the PC head after the mobile head is optimized is the gyroscope. The terminology is called IMU sensor. Don't underestimate the gyroscope. The self-contained sampling rate of the mobile phone itself is very low. Poor, even if the picture is optimized, you will not get a stable picture, and developers will not continue to waste time developing excellent content.
The product of Samsung and oculus cooperation is gearvr. The reason why the experience is not inferior to the ordinary PC head display is that there is such an IMU board in the vr box, and it is a good idea. The fan of the fireworks is equipped with this depth-optimized nine-axis sensor. Adapt to most mainstream smartphones.
Below we will specifically test the experience of this product.
Exterior:Appearance believes that everyone has become accustomed to this homogenized shape, with the most powerful force represented by gearvr, and the violent five generations, the bird watch, and the replicas of countless Huaqiang North, but this follow the mainstream The appearance of the product is not annoying at all, and the volume can be controlled very well.
Take a closer look and the straps on both sides are tilted at an angle. We have said that this is to make the direction of force in the upper part of the back of the brain, so that the face can also fit well.
We did not test the weight of the phone to 249 grams, in line with current standards, plus the phone can be controlled at more than 400 grams.
The front panel feels comfortable and matte.
Open the front panel, the phone is the clamping method of the upper and lower buckles, pay attention to a detail, the upper buckle can slide, in order to avoid touching the power button.
On the side is the usb line, which can be pulled out and inserted into the mobile phone to transmit the gyroscope data.
The lens barrel is two perfect circles, which can make a better cutting process for the picture, and the image is closer to the elliptical field of view of the human eye.
The mask is foam and flannel, which is basically the same as similar products, the comfort is not bad, the space in the mask is enough, and it can support the wearing of myopia glasses.
The new version of the optical lens of the extreme screen we compared with the gearvr, the result is surprisingly similar data, diameter 37mm, focal length of about 37mm, the experience is basically the same, the most obvious features are clear lens edge, low dispersion, low distortion, and optical The algorithm of this fireworks curtain basically uses the data of gearvr. In fact, it is not surprising that whether it is the IMU sensor or the underlying technology, the domestic fireworks are constantly learning its strengths.
Of course, like the Samsung gear vr, the fireworks curtain does not have the adjustment of the distance, which is related to the fact that the single screen of the mobile phone cannot be scientifically adjusted.
Software and hardware customization: powerful underlying technical support
We didn't focus on hardware, because Fireworks is a startup that focuses on the underlying development of software. ATW is one of the core technologies. From the beginning of gear vr, this keyword has been popularized in the industry. The role is to use the frame interpolation technology to maintain the stability of the picture and better rendering quality, so the GPU is better played.
Its built-in high-precision nine-axis sensor is a standard module for experience. The high-performance MCU chip is responsible for collecting the data of the nine-axis sensor, and then doing the preliminary data processing and outputting it to the screen of the mobile phone. The biggest benefit is that the user is experiencing the experience. In VR, the delay is low, the picture is smooth and not stuck, no drift phenomenon, accurate direction, and it is more comfortable than ordinary mobile VR application, and it is not easy to be dizzy.
Other hardware parameters: adapt to micusb and type c, compatible with 5-6 inch mobile phone, need to comply with Android 4.4 system and above and OTG function, support visual acuity adjustment 0-600 degrees at the top, and three buttons on the right side for light interaction.
Infrared distance sensorThe sensor that automatically senses the face, the standby screen when we take off the headset, automatically calibrates the screen directly in front of the screen, without the need for a second calibration screen. Of course, if the user changes a position, change direction, recalibrate the front only needs to be long Press the Escape button, we strongly agree with its intimate and convenient operation.
The actual app experience of the Essence Store gave us a high score of 80 (gearvr100 points).
Test Methods:The method we tested is rather rough. Several mainstream apps are installed on the average mobile phone, and the fireworks are compared. The test method: test the normal app around the eight characters, look at the restored location. After several tests, we found that the screen appeared in addition to shaking the phone. Obvious afterglow and delay, basically when we return to the original position, the picture is not in the original position. We returned to the curtain, the test method is that the mobile phone is placed on the desktop, we shake the body to do multiple sports, see the reaction of the picture, no matter how we shake, and finally return to the initial position. Its final performance is summarized in three points: low latency, no drift, high frame rate.
At present, there are 6 exclusive applications for the Essence store. At least three or four games are updated every month. There are already extreme OS, Fireworks, Cat Adventure, Fruit Ninja Dart, InfiniteFlight, Smash Way, among them Fireworks Cinema It has been introduced in detail in the third class of the Pirates of the Dream Geek. The rendering, lighting, and spatial ratio have restored a real IMAX theater. In the Extreme Screen OS, we can see a lot of 23D movies and panoramic videos online. This has made up for the content shortage to a certain extent, at least with the fireworks theater to watch the video, the effect is still somewhat shocking. The update of the game has to be supported by more users and developers. At present, the VR content of the entire market is still very scarce, and the final market share can generate energy for the follow-up of an excellent product. Future Fireworks will make corresponding VR underlying technical support for various mobile phone manufacturers. With the release of Android7, VR will be more excavated. The pirate geek has learned that the Fireworks Workshop is doing the new vr mode. Adaptation, the VR experience of the mobile phone will become stronger and stronger. If you let me comment on today's product in one sentence, it is: the polar screen system is a very good VR system.
end:As a technology company, Fireworks Workshop has made great progress in the optimization of the bottom layer. When we put on the experience for the first time, our comparison object is Samsung gearvr. If the actual test is performed with Samsung's flagship machine, it is infinitely close to the level of gearvr. ATW's low-latency technology has also been applied to this product. The fireworks sdk developed independently by itself has also been released at the same time. Both the gyroscope and the picture performance are very smooth, which is on the low-end machine, such as the charm blue note3 thousand yuan machine. It is also possible to run VR applications with an acceptable delay.
In a word, we only recommend the right product. A team that is serious about the underlying development technology is worthy of respect. There is not much nonsense. How can the product be experienced by itself? The Pirates of the Dream is a public The media welcomes all kinds of Tucao. Interested friends can leave a message in our official forum.
