In 2016, more and more virtual reality devices were released one after another. Practitioners shouted the official arrival of “VR first yearâ€. However, driven by interests and capital, VR has become chaotic in the Chinese market, and the counterfeiters are coming. The more people, the more and more arrogant, from the concept of speculation, the falsification of parameters, to the content of the content, financing fraud, etc., all reflect the chaos of this industry, which also digs many "deep water" for VR products on the market. Area". Putting aside an article on the explosion of the article, I put down a press conference with a pile of cars and horses. The mixed and good, mixed, swindlers, and cottages have become the status quo of the VR industry. In addition to Oculus, HTC, Sony, IDEALENS, Samsung and many other companies that really master VR core technology, there are too many spoilers in the VR industry: mobile phone companies that are transformed by mobile technology. "0 technology" company that network technology and the cottage manufacturing company "forced" jointly; more "Pseudo-VR really hype" brand company only for brushing the sense of existence... This also caused most consumers and media to VR concept Blurring, misleading for the VR industry. When you see the gorgeous words of “Excellent immersionâ€, “Extreme experience†and “Super large viewing angle†on the official website of each brand, you may have mistakenly entered “the picture†when you want to pay for it. VR is not a "net red" product that is held by these vocabulary. Its technical content is extremely high, and FOV is a symbolic parameter that reflects the optical core technology. The FOV is the angle between the edge of the display device and the point of view (eyes). Simply put, you can clearly see the content of the picture + the afterglow. The angle AOB is the horizontal angle of view and the angle BOC is the vertical angle of view. The core of virtual reality lies in immersion, and the key to achieving immersion is panorama. FOV represents the panoramic angle you see. According to the characteristics of the human eye, horizontal scanning activities are more and more relaxed. Most of our browsing behaviors are horizontal scanning. The total horizontal viewing angle of ordinary people's eyes is close to 200~220°, but the clear viewing angle of both eyes can be imaged. 120°, that is, under normal conditions, the most convenient imaging angle of view of the human eye is 120°. The picture presented by the VR device is more in line with the human body structure and behavioral habits to ensure the realization of immersion, so the FOV is too low. Can't bring us immersion. Human eye angle of view For the current VR products, the 100° FOV has become an industry-standard minimum. Below this degree, you can see not only a limited range, but also the black side of the picture, so only 100~ 120° is likely to create a good virtual reality experience. Mainstream VR product viewing angle In fact, by shortening the distance between the eye and the lens, a thick lens can also be used to enlarge the viewing angle, but with the increase in weight of the product, if the magnification is too high, the crystal lattice of the screen will be more serious. Even causing eye damage. Shorten the distance to get a bigger FOV principle At present, there are also VR products with a FOV of 110° on the market, but this is not a limit. The VR all-in-one IDEALENS K2, which was just released in Seattle, claims to have reached the true FOV of 120°, which has become a A milestone in technological breakthroughs. According to IDEALENS officially, IDEALENS K2 can achieve 120° FOV and it has accumulated over the years. More importantly, IDEALENS has a new optical solution of more than 160° and established the protection of international patent barriers. The great prospect of VR has brought in the influx of various manufacturers and capital, which itself is a good thing for the development of VR. However, if we pursue short-term benefits without regard to the long-term development of the industry, it will bring great harm to the current VR market, and also consume the enthusiasm of users, which will eventually lead to more tortuous development of the entire industry, and even collapse. Only by making serious breakthroughs in technology and making good products in a down-to-earth manner is what all VR vendors and VR practitioners should do. For consumers, if you don't know how to identify, try to choose a technically recognized device like Oculus, HTC, IDEALENS, to ensure that you are opening the real VR world.
