Analysis: VR Headset Display Device General Specification Alliance Standard

After savage growth for up to one year, domestic VR practitioners finally ushered in the day when industry standards were announced:

On April 6, 2017, in the "Virtual Reality" International Cooperation, Open Winning Summit Forum and Industry Standards Conference, co-sponsored by Xinhuanet.com and China Electronic Technology Standards, "Virtual Reality Headset Display "General specification of equipment" was formally announced. As a result, new problems have emerged:

For domestic VR people who are still sticking to the position of “localization of VR hardware equipment”, what is in front of them is a well-documented new round of survival of the fittest, or is it a new situation that can be exploited by other people?

Let us take a closer look.

Under the Ordinance: More Flexible Than You Think

"Our standard is a self-developed group standard; when it comes to this self-developed 'group standard', comrades familiar with standardization must ask, what is this concept? Then we must mention that China's standardization reform : Starting from March 2015, the State Council issued No. 13 document on the notification of deepening the national standardization reform program. The State Council issued the No. 66 document and the No. 88 document issued by the National Standards Committee until February 2017. Li Keqiang The Prime Minister passed the reform plan of the Standardization Law at the State Council office meeting, and this series of national initiatives all show that our country is vigorously carrying out large-scale standardization reforms. What is the purpose of the reform? We can see that its purpose It is the establishment of a new standard system that is coordinated by the government-led formulation and the market's self-developed standards, and a standardized management plan that is jointly managed by the government and the market. In this respect, it is most important from the perspective of standardization legislation. Established the legal status of 'group standards'. In the past, we were single-government-led and now we have The market developed its own standards, 'government-led' protection of basics, 'market development' to improve competitiveness. Before our government led a total of six types of standards, now through standardized reforms, streamlined to four categories, are 'mandatory national standards' 'Recommended National Standards' 'Recommended Industrial Standards' and 'Recommended Local Standards'. Then you can notice that the last 'self-developed standards' are divided into 'group standards' and 'level standards', this 'group standards' 'This is the first time that we have been able to rise to a legal status, so our standard is the 'self-developed group standard'."

- The above content was the scene of the conference on April 6th, Wang Cong, chairman of the Virtual Reality Industry Alliance Standard Committee, made an excerpt. In short, the "General Specification for Virtual Reality Head-mounted Display Devices" announced this time is not a strict, unrelenting one-size-fits-all force-enforcement standard, but an elastic product formulated in accordance with the market's current mainstream product specification parameters. Specification - As for how large this floating range is, please look down:

The first is about product classification. “The external virtual head-mounted display device” refers to the VR head-mounted display connected to the host computer, such as the HTC Vive and Oculus Rift. (Incidentally, the PSVR really did not appear in this speech.) The "integrated virtual reality head-mounted display device" is a VR head-mounted display device that integrates CPU, GPU, and other computing components. (In addition to being integrated in the head display body, products integrated in the handle and the like also belong to this classification.) Next) As for the "case-type virtual reality head-mounted display device", we are not unfamiliar with the mobile phone VR box. As a result, at least in terms of product classification criteria, it is well documented. If there is no special explanation, the following analysis will be carried out.

However, although there are three categories in terms of product type, it is not necessary that the standards implemented at the parametric level have to correspond one by one—for example, the parameters under the “angle of field” standard are only two levels. , Friends who are familiar with mainstream VR devices in the market know which products are included in the “level 1 indicator” nominally >100°. As long as >80° are qualified “secondary indicators”, the spokesperson clearly stated that this is “everyday The conventional perspective of the viewing experience - it is not difficult to see that this VR device industry standard is obviously designed based on the functional positioning of actual products, and it can be said that the degree of compliance is full.

Of course, the integration of financial and financial resources, but if the actual number, we can still find a few details of the slot: for example, there are only two standard "resolution" parameters, of which the "secondary index" at first glance The following is the low-end standard of the corresponding shell-type virtual reality head-mounted display device. Actually, the single-eye resolution of the PSVR is also this level - it is regrettable that the best-selling pillar VR devices on the global market are under the national standard. Actually falling to the same level as the 12.9 yuan mobile phone VR box of the micro-transporter, it was thought that the PSVR did not become a reference device for the classification criteria. The question of Sony's public relations in the end was really intriguing.

There may be a friend who is puzzled by the description of “communicating”. It doesn’t matter. Let's look at two key parameters. I believe everyone can suddenly realize – the first one is the “display refresh rate” in the above figure. Note and the first few The figure is different, this indicator parameter clearly defines the corresponding product type in front of it, and many one-machine products that are highly expected by industry players only need to meet the refresh rate higher than 60 Hz to declare compliance, and are considered as high-end products. The external virtual reality head-mounted display device also has a second-level indicator scheme that is ≥60Hz OK. This compares with the prevailing mainstream view of "90Hz is the VR device entry benchmark" that was popular in the industry last year. What is behind the compromise concessions? Intention, it is easy to understand that some domestically produced PC-side VR head-mounted advertising is not difficult to understand. At least in my opinion, the reduced standard line is obviously opening the way for a lower PC platform configuration demand. As for whether this concession is worth it, the immediate 60Hz picture can not be accepted by the public. In time, the market will give us an answer. .

In the end, let's look at the new indicator of the “system delay” parameter, which is the 33ms between the highest standard and the number of figures advertised in mainstream products last year. Regardless of whether it is on the PPT, or by product standards, "Exit" was clearly explained by the spokesperson at the conference venue at that time. Excerpts are as follows:

"In addition, you may have noticed that there is still a sentence, 'or given by the product standard' - it can be said that some manufacturers may not reach 45 milliseconds, then we also hope that they can promote this standard, We will continue to move forward and achieve transformation and upgrading as soon as possible."

Combining the previous paragraphs, what exactly does "community" mean? Everyone should understand it?

After standard: from device to content

In summary, it is not difficult to see that "general specification for virtual reality head-mounted display devices" does not lack market guidance, but a more direct role should be to filter low-end equipment that ignores the concept of product quality hype. - Although it is a fatal blow to the advocates of the VR market bubble, it is obviously not a bad thing for those who are still unwilling to give up the industry.

In addition, at the end of this specification's announcement, the spokesperson of the conference drew up another topic:

"In addition to starting with hardware, we will also have some plans for software and content. The basic requirements and test methods for virtual reality application software, and secondly, the classification and evaluation criteria for virtual reality content. This is also the work we will start next. ."

- Well, you're still stuck with the domestic developers who shoot the WAVE SHOOTER shooter and shoot the zombie game. Do you know what to do next?
