Let's talk about VR's past, present and future. A few netizens left a message for me. I'll read it one by one. A friend with the internet name of Dashan Zhishi said, can we use a simple metaphor to briefly describe the differences and interrelations between VR, AR and holographic projection. So, man, give you the simplest way to judge. The first one is to wear a helmet and not to see the reality, but to see the man-made virtual structure of VR. Second, with glasses, you can see both reality and virtual ar. third, take off all of them. What you can see with your eyes is holographic projection. Therefore, human beings will realize VR first, then ar. finally, holographic projection is the ultimate mode.

Another netizen named Jason Li asked, what's the difference between VR and AR devices in the market price? The price of VR is wide. The cheapest one is about 100 yuan, and the expensive one is more than 4K yuan. The AR equipment is about 7k-20k. By the way, the price of holography, a set of slightly more mature holographic equipment, at least more than 3 million. Netizen T.I said, Long Ge can introduce a set of VR equipment with high cost performance. I will use it to play games with a budget of less than 3K. Ah, if you mainly play games, I suggest you still use PC VR, because what kind of all-in-one machine and what mobile phone rack can only watch video. However, if it is within 3k, I recommend 3 glasses D2 is quite good in terms of comfort and image quality. There is no problem playing the game. You can still have 500 meals left

Is VR not enough? And ar?

In the last issue, we talked about the essence of VR's innovation power. It is a way that human beings try to use virtualization to simulate and change the world, so as to reduce the cost of obtaining information. And the purpose of AR is to further improve the efficiency. Of course, when it comes to holographic projection, all communication and information transmission between human society will reach the extreme of high efficiency. We're not going to talk about holographic projection today, because it's so far away from us. Let's talk about AR today, augmented reality. Although we can get information through mobile phones, TV and other ways, it is still a bit troublesome. We have to take out our mobile phones and send wechat messages. You have to use computers to work and play games. You have to get images through TV screens. There was an ad called a day made of glass, which describes that human beings have entered a multi screen era, For example, PCs, mobile phones, computers, televisions, car navigation, doorbells and even watches, refrigerators and routers all have screens. These screens are used to display information. But when human beings are constantly switching back and forth between various screens, those Frankenstein scientists in Silicon Valley begin to think that if everyone has his own glasses, even contact lenses, Is it not a wonderful thing that we can connect all things? At this time, the ubiquitous screen around should disappear. Mobile phones, computers, TVs and all kinds of monitors are not needed. When you need to get information, smart glasses will show you everything you need and interact with it more intuitively. Behind it is the support of cloud computing, big data and high-speed wireless network. At this time, you will understand that life is not just about the present, but also a mirage.

Major companies compete for the AR sector

Some people say that AR is not as mysterious as I said. Now many of these app applications, such as IKEA furniture selection, you just open the app and mobile phone camera, scan the room, and the image of IKEA furniture will appear in your mobile phone, and the size and position can be adjusted as you like. Isn't it also called ar? It's not that amazing. But in essence, I can only say too young too simple Sometimes is also naive. All these apps on the market claim to be ar, which involves a little concept of ar. it uses cameras to capture the real world, and then render some elements to present to users in the form of video. This technology sprouted in 2008, and has matured in 10 years. It is not only simple, but also not easy to use, so it has not been an industry Chain.

Of course, there is a VR + camera = ar mode in the world now. For example, HTC's vive has a camera installed on it. Although it is relatively simple to implement AR in this way, you can imagine that the image captured by the camera is only a 2D image, and the quality of the world directly seen by the naked eye is still very poor. And the video from the acquisition to the display is always delayed. If it is inconsistent with the somatosensory signal, it will cause the feeling of dizziness and vomiting, want to vomit, want to vomit, understand?

And then I'll tell you what kind of products can be called real ar. We commonly call transparent glasses AR, which is the virtual image that can be directly seen through the lens. This method is also the research direction of the most powerful companies, such as Microsoft and Google. OK, so what principle does transparent glasses use to let people see the picture is 3D? So there are two mainstream technologies on the market to realize ar 3D effect of transparent glasses: stereoscopic 3D (stereoscopic 3D) and light field (light field). Let's talk about Stereocopic 3D. What's its core principle? I don't understand. The game player wants to know more about the 3D. We can see the relevant articles in our official account. We simply put the light into your retina, so that you can see the real world and see the illusion of the virtual world. However, almost all AR and VR glasses on the market, such as Google glasses, Microsoft hololens, oculus and so on, can imitate 3D effects, but there is a problem. The human eye has the function of auto focusing and convergence. For example, when you focus on something, only this thing is clear, and all the surrounding objects will become blurred, but stereoscopic The 3D images are clear in every corner, and there is no focusing function. These are not in line with the laws of the human eye in nature. Therefore, the brain will be confused, and it will cause dizziness and vomiting for a long time. Do you understand? I feel like vomiting!

The next light field is really black technology. Compared with other UAV bracelets VR head display, they are all black fungus. The academic concept of light field has been proposed as early as 1939. It is used to describe the intensity, direction and wavelength of light at any point in space at any time. This passage is from Baidu Encyclopedia. I feel a little dizzy. In short, remember that the light field will make you really unable to distinguish whether what you see is true or not, and it completely feels that it is real.

Magic leap is a fraud company?

At present, the most popular and controversial ar company, magic leap, has spread a lot of videos from this company in October 2015, such as what whales jump up on the basketball court, aliens raid offices and play real CS In just a few days, these videos have exploded in the circle of friends. As the insiders of the industry know, this is definitely a concept film. It's duangduang's stunt. The video is a combination of special effects, which can't be achieved by the existing technology. However, don't underestimate magic leap. It has now obtained round C financing, including Alibaba, Google and other giants. Now the market value is $5.4 billion, and it has definitely become a star in the AR industry. But the problem is, as of now a few years have passed, burning more than a billion dollars. So far, the company has not released any products, and some even doubt whether this company is the most powerful deceptive company in history.

Why is there a dispute? The tech giant still wants to vote. I believe that the projects followed up by Google and Ali are totally deceptive to the company. Should there be one or two brushes? If so, how can it be achieved? We know that the fidelity of general devices depends on the resolution of the screen, but magic Leap uses the light field of black technology just mentioned by me to restore the image, which is the same as that of the human eye. Let's talk about the principle briefly. When a person is in front of us, the light emitted by every cell on his skin will be superimposed to form a light field. In theory, as long as we have such a device, it can not only record the person's light field completely, but also restore the information of the light field to the original light and emit it like a projector. Then when your retina receives the light, you will think that you have seen a real person in front of you. Magic leap is to use the natural image production method, and the technology is the same as the daily work of human eyes. Whether you close one eye or under strong light and weak light, the experience will not be affected. What you see is not a computer-generated monster, but an absolutely real image of 3D model displayed in front of you. This kind of effect is very real and cool. It is hard to describe in words. This is the real AR and the real augmented reality. How do I feel that magic leap is paying me for advertising, right. OK, when can magic leap make real ar products for everyone? Seriously, I don't know, but I searched their teams and investors on the Internet, and I can introduce them to you.

The founder is Rony, an optical fiber robot scientist. Other people are the top computer vision bulls in Silicon Valley. I don't know a lot of English names. Of course, in addition to the team force, Google, a top technology company, has invested $580 million in direct Angel round, which means that you can do the underlying technology safely in a fully closed state, and don't worry about being unable to pay wages. Google also brings Qualcomm as a strategic investor to assist in the development of photonic field chips. You can see that other chips have started their own research and development, and they will come out at the end of April The prototype of optical core; also let the No.2 person and the person in charge of core products join the board of directors to participate in the management; in short, Google is fully committed to magic leap.

Why does Google love magic leap?

To give money, to people, to technology, to the market, why does Google treat a start-up company as its own son for no reason? Why is Google so persistent in AR when it fails the glass generation and wants to vote for magic leap? If you think it's just for money, like a woman who would rather cry in a BMW than laugh on a bicycle? That's too small to look at Google's intelligence quotient, from Google's earliest search engine to Android open source algorithm, from taking care of world go Master Li Shishi's elfagou to Google's moon landing plan The ultimate goal of all this is to achieve the true meaning of Artificial Intelligence AI, and to make robots beyond the human brain technology singularity into reality. Artificial intelligence can change the world or replace human beings only with hands, feet and bodies composed of hardware. Ruling human beings is the ultimate goal of Google. In science fiction movies, the reality that companies dominate human beings really needs to be realized. I beg your pardon? Baidu, oh yes, baidu is also a search engine. It also successfully solved the problem that our office workers eat takeout at noon every day, which is also a kind of black technology with Chinese characteristics socialism.

However, it will take more than 3 years for us to realize the full maturity of VR, so AR with more technical problems than VR obviously needs to continue to make more efforts. In addition to a series of problems of VR itself, AR has its own display and lens problems. Nowadays, most of AR glasses are based on spectroscope, such as Google glass, hololens and meta 2. A simple spectroscope is a 45 degree angle, which reflects the light produced by the monitor from the eyeglass frame into the human eye, and at the same time allows the light of the real world to penetrate in. Although it is simple and cheap, the lenses are too thick and heavy to be worn for a long time. An Israeli company, lumus, made a photoconductive technology to make the lens very thin. Unfortunately, the process is complex and the cost is too high. To be thin, and the field of view is more than 120 degrees, the lens still has a long way to go.

How long will it take for AR to become the mainstream product in our life? Compared with VR, I am more pessimistic about it. I estimate it will take 8-10 years, maybe even longer. Because the maturity of AR industry chain can not be solved by quantitative change, it must be determined by qualitative change. However, there is no doubt that this is the inevitable direction of human computer development.

After reading the current situation of Longmen's energy industry, I talked about the current situation of our energy industry in detail. (end)
