White common sense: 10 yuan and 7K VR what's the difference?

What is VR?

VR, the full name of Virtual Reality, is literally translated into virtual reality in Chinese. It was proposed by Jaron Lanier, the founder of VPL in the United States, in the early 1980s. Simply put, it is through the computer to build a virtual world, people can get a real world sensory experience in this virtual world, specifically refer to the science fiction movie "Matrix" and the animation "Sword Art Online."

Currently, devices that experience VR are mainly head-worn devices, ie, head-mounted displays with two optical lenses. The principle is that the two display screens have a certain picture difference, and then the professional optical lens enlarges the display screen to obtain a 3D experience, which can be simply understood as the principle of a 3D movie for the left and right eyes. Because the enlarged screen covers the entire human eye's visible range, it will produce a certain degree of immersion, as if it were in the virtual world.

In fact VR is such a two screen

VR equipment has various names, is it right?

Since it needs to be worn on the head and covers the eyes during use, the VR device is also called "VR helmet" or "VR glasses." Another VR device has a built-in display, so it will also be called "VR Headset" (head-mounted display). In addition, VR devices have different product classifications and different names. After sitting down, Xiao Bian is ready to drive.

Currently, VR devices are mainly divided into three categories: "VR Headsets" used by connected PCs, "VR Integrated Machines" with built-in processors that can be used independently, and "Mobile Phone VR Boxes" that need to be used with mobile phones. Just form a high school low, three product grades, the price is from very high to very low:

HTC Vive is currently the only high-end VR headset sold by the State Bank. The bare metal price is 6888 yuan.

Search "VR" on Taobao, the lowest price mobile VR box is only 9.8 yuan

Also under the name of VR, why VR head display will be so expensive, why mobile VR box so cheap! First, VR head display built-in high hardware parameters of the screen, and second, VR head display has a more professional optics Lens and technology, the third is VR head display has the top content of mobile phone VR box. After reading the detailed description below, you will know the huge gap between the mobile VR box and the VR headset. Don't say why the HTC Vive or Oculus is so expensive.

VR heads: parameter cattle experience strong selling price

As we all know, the current three major VR heads are HTC Vive, Oculus Rift and PS VR, the first two have been on the market, PS VR international version listed in October. As a representative of the VR headset, the hardware parameters of the HTC Vive and Oculus Rift are very similar: two 1080 x 1200 OLED displays, a refresh rate of 90 frames per second, a delay of within 22 milliseconds, and a field of view of about 110 degrees. Corner (The larger the field of view, the wider the range of images that can be seen and the more immersive).

Due to the above-mentioned hard power, VR head display can provide a relatively clear picture at present, with extremely fast response speed, almost no smearing of the picture, and low vertigo feeling.

In addition, the VR head display is equipped with a spatial positioning and motion capture system, such as the HTC Vive, and all actions after wearing a helmet can almost obtain 1:1 motion feedback in the VR. For example, the top GIF image, when the bullets shoot over, the body can escape and feedback to the game! This is the VR head shows the strongest weapon for high-end VR devices, whether it is a mobile phone VR box or a VR machine, there is currently no Supporting space positioning & motion capture system.

The Oculus and PS VR have a much smaller spatial activity range than the HTC Vive. However, with the same motion capture system, they can achieve almost 1:1 hand movement feedback, although they cannot move around in a wide range.

However, the VR headset has the biggest problem. It needs to be used with a relatively high-profile PC host. The graphics card has to be GTX970-class, and the CPU can also play i3. Assuming you only need to buy a GTX970 graphics card, playing VR headset costs at least 1W. VR head shots are really expensive, but expensive is justified. Don't say anything is not clear enough. The game is not fun. You first played HTC Vive and Oculus. Besides, now more and more VR games, masterpiece will certainly have.

In the end, the Sony PS VR, which is widely mentioned, is also a VR head display. However, the PS VR must be connected to a PS4 host and cannot be used by a PC (unless it is a big god, you can play HTC Vive and Oculus games). PS VR announced the international version of the price of 399 US dollars, about 2600 yuan, while the PS4 console price is only 2,000 yuan, and the penetration rate is very high, so PS VR's attention is so high!

However, 399 US dollars is only the price of the head, but also with the PS VR transmission box, PS Camera motion capture camera and PS Move handle. Sony's package price is 500 US dollars, about 3,200 yuan, and bareheaded bare metal price difference is not much, then look forward to the Hong Kong Bank and State Bank prices. The number and quality of games must be dominated by PS. HTC Vive and Oculus also need game masterpieces to support content.

The above is the VR headshot in the consumer field. The consumer version of VR is a trade-off between cost and performance. In the commercial field, there are many VR heads with relatively high costs but hardware parameters and performance. Here, Xiao Bian also introduced it by the way.

Infinitus Prime's tVR, equipped with a 5K screen, a resolution of 5120x1440, a viewing angle of 140 degrees, close to the human eye of 160 degrees, but the volume is a bit large, the weight is also a bit heavy. Price $ 3,000, about 19,736 yuan, interested in in-depth understanding, please see "put on 5K screen VR headlights foreign media Xiaobian shocked! However, selling nearly 2W."

The StarVR produced by Starbreeze Studio, with a single eye resolution of 2560x1440 and a stunning 210° field of view, can be comparable to the true vision of the human eye. Acer has invested in StarVR and expects to bring a consumer version. The current price is expected to be US$1,000. About 6685 yuan. If you want to know more about it, please also look at "The VR Head Shot! Can you imagine the experience of a 5K screen with a viewing angle of 210 degrees?"

Mobile VR box: In addition to slag or residue

Why first introduce the mobile phone VR box? Xiao Bian is a mental machine BOY, introduced the high-end VR head display, immediately turned to the lowest-end mobile phone VR box, in order to tell you: the phone VR box is the residue, residue!

The mobile phone VR box was originally developed by Google to promote the concept of mobile VR. It used cardboard to create a “Google Cardboard” cardboard VR box. With the use of mobile phones, it was possible to experience the VR experience at a very low cost. However, there was no interpupillary distance. The adjustment of the distance, the clarity should not be entangled, the purpose is mainly to popularize VR.

Subsequently, taking advantage of the blazing VR, some manufacturers began to develop the concept of Google cardboard VR box into a mobile VR box, mainly to replace the plastic shell with a design sense, after a certain design of the optical lens, and to adjust the interpupillary distance, object distance The design can get a superior VR experience.

Because of the low manufacturing cost, the word VR is the hottest thing in the IT world. Therefore, various copycat factories have launched VR boxes and have advertised various slogans to capture eyeballs and boast various performances. In fact, the current market for mobile phone VR box, basically no technical content, the main performance processing is completed by the phone, content processing, display, head movement and other sensors. The mobile phone VR box only serves as a shelf! Hey, hit the face! Differentiating also wearing comfort, and the quality of the optical lens used.

However, Gear VR, which Samsung and Oculus have jointly launched, allows industry and gamers to see the possibility of high-end mobile VR boxes, with a touchpad and a VR application store with high-quality content. The domestic manufacturers with a very sensitive sense of smell naturally follow suit.

After the Samsung Gear VR was launched, various domestic VR application stores were also launched. A mobile phone VR box was not embarrassed to be sold without a dedicated APP.

As for content, in fact, the contents of domestic VR application stores are basically the same, nothing more than panoramic video + beautiful panoramic video + 3D movies + VR games without connotation, the difference is who the APP interface looks better, better operation, BUG less slightly .

Samsung also has its own VR application store. To know that Gear VR was developed in cooperation with Oculus, Oculus also compatible Samsung mobile phones with some games, such as "GUNJACK" in the above picture, so Samsung VR stores are basically exclusive content. The quality of the game is also unmatched by domestic production. Samsung Gear VR must be used with Samsung mobile phones, the minimum requirement is S6, this is to ensure a high quality VR experience, domestic mobile phone manufacturers, of course, have to follow suit.

Currently, Huawei, LeTV, ASUS, and ZTE have launched a mobile VR box similar to Samsung Gear VR, which must be used with their own mobile phones. The main difference lies in the hardware configuration of the mobile phone. As for content, it is difficult to compete with the Samsung VR App Store in a short period of time, sharing the same content as an ordinary mobile phone VR box. Meizu, Xiaomi, OPPO, VIVO and other domestic mobile phone manufacturers are expected to launch similar VR devices, but solving content bottlenecks is the most important.

Back to create a mobile VR device Google, this year's I / O conference released a mobile VR platform "Daydream", literal translation of daydreaming. Simply put, this is a VR mode built into the latest Android N system. It is not a physical VR device. The purpose is to unify the mobile VR standard so that content and game makers can develop high-quality mobile VR content. .

Google at the conference exhibited a set of "Daydream" entity VR reference design, it is currently unknown whether Google will launch its own mobile VR box. In addition, Google also said that mobile phones supporting the Daydream platform must have powerful CPUs and GPUs, as well as high-response, low-afterglow displays. Currently, a number of mobile phone manufacturers are developing mobile phones that comply with Daydream standards, including domestic manufacturers such as Huawei's Xiaoxing ZTE. But Google also said that there is currently no cell phone on the market that meets the standard, but Google internally uses the Nexus 6P as a development machine.

After introducing the mobile phone VR box, why is it far less than the VR head? The key factors are three:

First, many mobile phones do not use OLED screens. The screen response speed is slow, and it also causes screen smearing. Most people will not notice it under normal use conditions, but it is very obvious when placed in a VR box: the picture response is slow, and when the head rotates, the picture responds slowly after half a beat. Then there is serious smear, which leads to a sharper decline in the overall picture. Seriously, it can also cause dizziness and nausea.

Second, the FOV (Field of View) is an important parameter that determines the visual range of the VR screen. The mobile phone VR box is basically 96 degrees, and the three VR heads are between 110 and 120 degrees. The StarVR introduced above has a terrible 210 degrees. The larger the FOV, the greater the range of images that can be seen, just as the different visual displays provide different visual enjoyment. Some poor quality, cottage mobile VR boxes, FOV even only 5,60 degrees, is simply looking at the telescope.

Third, easy to make halo! As almost all mobile phone VR box, do not have a spatial positioning system and motion capture system, can only rely on the sensor of the mobile phone to get a simple somatosensory: turn the head, the picture also follow the move, only That's it. However, including Samsung, as well as domestic manufacturers are also looking for partners, or develop their own positioning, motion capture system. But not yet, if you play on those more intense games, minutes will dizzy, especially when the screen moves back and forth, just like motion sickness!

If you do not want to faint, it is best to look at some simple video, movies, such as small movies, so the biggest use of mobile VR box is to look at the film! Although the mobile phone VR box and VR head display technology gap is very large, but in Looking at the film experience, the $10 cell phone VR box is almost no different from the $6888 HTC Vive. Mobile phone VR box, born for watching movies.

VR machine: that is, the built-in mobile phone

Congratulations, this article is finally coming to an end. Can a small partner who can watch it all the way down, do you think that you already know very much about VR? NONONO! VR device has an intermediate product between the mobile VR box and VR headset: VR machine .

VR machine, simply speaking, is an evolutionary version of the mobile VR box. The mobile phone is built into the VR box. There is no difference between the VR box and the phone. However, as the overall hardware can be customized by the manufacturer, optical technology can also be optimized, and the screen quality will be much higher than the mobile VR box. At present, the VR integrated machine on the market can basically provide high response speed comparable to high-end VR heads, low-brightness without smearing, and 2K or even 4K screens.

The birth of VR all-in-ones is more of a selling point with “no cables”, because VR headsets need to be connected to PCs, and they will be picked up by the cable during play. However, the mobile phone VR box is actually not a cable, and the performance of the all-in-one machine is the same as that of a high-end mobile phone. The only advantage is that the screen quality and optical technology are stronger. The three key factors summarized above are equally applicable to the VR all-in-one.

Not to mention that the VR all-in-one machine does not have a spatial positioning and motion capture system. The content is more directly the content of the mobile phone VR, there is no exclusive high-quality applications and games. At this point, the largest domestic friend is the most daring (this is not a soft text, Xiao Bian said the truth), after the release of its VR one machine M2.

Although M2 shipped, users were disappointed not to see the big difference from the mobile VR box. Da Peng has repeatedly stated that he will establish cooperation with famous game developers and will launch a series of high-quality VR games. However, no competitive VR games have yet been seen in M2.

In addition, DaPin and Ximmerse are collaborating to develop a motion tracking controller for spatial positioning and motion capture solutions, and also announced that they will launch two sets of mobile VR spatial positioning systems. One is M-Polaris mobile VR high-precision optics. The space positioning program and the second is a large-space high-precision mobile VR laser positioning solution that cooperates with G-Wearables. It can be seen that such domestically produced VR manufacturers such as Da Peng have courage in their ideas.

However, for VR all-in-one manufacturers, the first-of-its-kind spatial positioning and motion capture system allows the VR all-in-one to widen the gap with the VR box of the mobile phone and approach the VR head. Secondly, we need to improve the quality of content, especially after Google releases Daydream. Should we continue to develop our own ecosystem, or should we embrace Google? The VR all-in-one machine needs to solve these problems. Otherwise, the price of RMB 2,3000 will be exceeded. Obviously.

What VR to buy, I think you already have the answer

The 10 yuan mobile phone VR box, 3,000 yuan VR one machine, 7000 yuan VR head display, different prices determine the different VR experience grades, the equipment itself and the technology involved in the technology is also the corresponding price. If someone asks you: "I heard that VR is very hot recently. I want to experience it. What should I buy?", please decisively say "On the Taobao search VR buy the cheapest, small movie resources to sweep down the QR code on the line ".

Most people only want to experience VR's screen experience, and they are more often bought for small movie resources. The VR machine is not much different from a cell phone VR box at present and it is not worth buying. As for the VR head, want to play games or decisively buy PS VR, as for the other two heads, to experience the game play like. If you are fascinated by the 1:1 somatosensory, then it will start HTC Vive.
