Hello, I'm Andy. Recently, we received a mobile VR headset from the domestic fireworks workshop, the pole screen generation. This one in hand is a prototype machine sent to the media. The consumer version has also been listed.Before the formal experience, I'd like to do this homework for you. The reason why we made a special evaluation for it is because most of the domestic mobile VR headwear products work on pure optical boxes, that is, the VR boxes we players often talk about are basically the same except for different optics, such as pupil distance adjustment, object distance adjustment and compatibility with various sizes. Therefore, we often see products hyped with this gimmick concept.
Then many people began to ask, what kind of VR box do you think has a good experience? It's just a plastic shell. Compared with the mainstream PC head display, it's too big. In fact, to understand how much the gap is, let's look at the principle. Almost all PC head displays (without spatial positioning) are equipped with standard 1000 Hz sampling gyroscopes, The picture depends on the powerful graphics card output of the host, so a very real picture output is obtained. After optimizing the picture, the only difference between the mobile headset and the PC head display is this gyroscope, which is called IMU sensor in professional terms. Don't underestimate this gyroscope. The sampling rate of the mobile phone is very low and the performance is poor. Even if the picture is optimized better, You won't get a stable picture, and developers won't continue to waste time developing good content.
The product of the joint cooperation between Samsung and oculus is gearvr. The reason why we experience the ordinary PC head display is that there is such an IMU board in the VR box. To get down to business, the pole screen generation of fireworks is equipped with this deeply optimized nine axis sensor, which is suitable for most mainstream smartphones.Let's test the experience of this product.appearance:
I believe everyone is used to this homogeneous appearance. Gearvr is the most powerful representative. There are storm five generations, bird look, and countless copies of Huaqiangbei. However, this appearance following the mainstream products is not annoying at all, and the volume can be controlled very well.Take a closer look. The belts on both sides are inclined upward at a certain angle. We once 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 fit well.The weight without mobile phone is 249g, which meets the current standard. In addition, the mobile phone can be controlled at more than 400g.
The front panel feels very comfortable and frosted.Open the front panel, and the phone is clamped by up and down clips. Pay attention to one detail. The upper buckle can slide to avoid touching the power button.On the side is a USB cable, which can be pulled out and inserted into the mobile phone for gyro data transmission.
The lens barrel is two positive circles, which can cut the picture better, and the imaging is closer to the oval field of view of the human eye.The mask is made of foam and flannelette, which is basically the same as similar products. It has a good sense of comfort. There is enough space in the mask to support wearing myopia glasses.Optical part:
We have compared the optical lens of the new polar screen with gearvr. The result is that the data are surprisingly similar. The diameter is 37mm, the focal length is about 37mm, and the experience effect is basically the same. The most obvious feature is that the lens edge is clear, low dispersion and low distortion. In fact, the application of optical algorithm for fireworks polar screen basically uses gearvr data. This is not surprising, Whether IMU sensor or underlying technology, domestic fireworks are constantly learning their advantages.Of course, like the Samsung gear VR, the fireworks pole screen does not have pupillary distance adjustment, which is related to the inability of the single screen of the mobile phone to scientifically adjust the pupillary distance.Software and hardware Customization: strong underlying technical support
We don't start with hardware, because fireworks is a start-up company that pays attention to the bottom development of software, and ATW is one of the most core technologies. The keyword has been popularized in the industry since gear VR. Its main role is to use framing technology to maintain the stability of the picture and better rendering quality, so GPU has been brought into better play.It has a built-in high-precision nine axis sensor, which is a standard module for experience. The high-performance MCU chip is responsible for collecting the data of the nine axis sensor, further doing preliminary data processing and outputting it to the mobile phone screen. The biggest benefit is that when users experience VR, the delay is low, the picture is smooth and does not get stuck, there is no drift phenomenon, the direction is accurate, and the experience is more comfortable than ordinary mobile VR applications, It's not easy to get dizzy.Other hardware parameters: suitable for micusb and type C, compatible with 5-6-inch mobile phones, above Android 4.4 system and OTG functions. Vision adjustment of 0-600 degrees is supported at the top, and three buttons are provided on the right to realize mild interaction.
Infrared distance sensorThe sensor that automatically senses the face will stand by when we take off the headset. After wearing it, it will automatically calibrate the front of the screen without secondary calibration. Of course, if the user changes the posture, changes the direction and recalibrates the front, he only needs to press the exit key for a long time. We highly agree with its intimate and convenient operation mode.We gave a high score of 80 (gearvr100) for the actual app experience of Jimu store.
Our test method is rough. Several mainstream apps are installed on ordinary mobile phones and compared with the fireworks pole screen. Test method: test the ordinary app around the eight characters and look at the restored position. After several tests, we found that except for the obvious afterglow and delay of the picture when shaking the mobile phone, basically when we return to the original position, the picture is not in the original position. We return to the pole screen. The test method is that the mobile phone is placed on the desktop. We shake the body for many times to see the response of the picture. No matter how we shake, we finally return to the initial position. Its final performance is summarized as three points: low delay, no drift and high frame rate.
At present, there are 6 exclusive applications in Jimu store. In the future, there will be at least three or four game updates per month. There are Jimu OS, fireworks theater, Mr. cat adventure, fruit ninja dart, infiniteflight and smash way. Among them, we have introduced the fireworks theater in detail in the third session of inception geek, and restored a real IMAX Theater in terms of rendering, light and shadow, space ratio, etc, In polar screen OS, we can see a lot of 23d movies and panoramic videos online. This makes up for the shortage of content to a certain extent. At least watching videos with fireworks cinemas has a shocking effect. The update of the game needs the support of more users and developers. At present, the VR content in the whole market is still very scarce, and the final market share can generate energy for the follow-up of an excellent product. In the future, the fireworks pole screen will provide corresponding VR underlying technical support for mobile phone manufacturers. With the release of Android 7, VR will be excavated to a greater extent. Inception geek exclusively learned that the fireworks workshop is adapting to the new VR mode, and the VR experience of mobile phones will be stronger and stronger. Let me comment on today's products in one sentence: the polar screen system is a very good VR system.
As a technology company, fireworks workshop has made great progress in the bottom optimization. When we put it on for the first time, our comparison object is Samsung gearvr. In the actual test, if we use Samsung flagship machine to experience, it is infinitely close to the level of gearvr. ATW's low delay technology has also been applied to this product, and the fireworks SDK independently developed by us has also been released at the same time, Both gyroscope and screen performance are very smooth, which can also run VR applications on low-end machines, such as Meilan note3000 Yuan machine, with an acceptable delay.
In a word, we only recommend the right products, a team that is seriously doing the bottom development technology is worth respectful. Make complaints about how the product can experience itself, the dream geeks as a public media, welcome all kinds of Tucao, and interested friends can go to our official forum to leave a message.
