Chapter 1067

Lying on the bed with his helmet, Chen Yushan obediently emptied his brain according to the instructions of Lu Zhou, without making any noise or thinking.

Gradually, a sense of sleepiness began to flow into my mind.

She could not help yawning, thinking that when she was going to sleep soon, there was a stab like an ant biting her back neck.

For a moment, something unexpected happened to her.

The darkness around her horizon, as shattered by a rainbow, instantly becomes fragmented and spreads out to the outside.

Surprised by this special effect, the darkness around Chen Yushan has been completely dispelled just as she is stupefied.

Like a cocoon, she has been in a blue grassland.

Yes, this grassland is blue.

And the sky is burning red.

Standing in this strange world, Chen Yushan raised her right hand and touched her cheek.

No touch.

But she did feel the hand on her face.

"And the helmet?"

Gone!?

His hands fumbled on his face strangely, Chen Yushan's expression became more and more surprised, his pupils were shaking unbelievable colors, and he murmured to himself, "am I asleep?"

Just as she hesitated to bite herself to confirm this, a familiar voice sounded in her ear.

"It's true to say that it's sleeping. The principle of this device is similar to the interference of dreams. Of course, there are some differences between this and the general situation when we dream. In contrast, it is more like an imagination actively induced by the stimulation of neural electrical signals Well, it's troublesome to explain it in popular language. You might as well understand it as being dreaming. "

The voice seemed to come from outside the world, but so close to where she is now.

Chen Yushan looks around and tries to stamp her feet.

It is expected that no sound will be made, and even the sole of the foot on the ground will not have any perception.

It's a strange feeling, just like your body doesn't belong to you, just use her perspective to explore the world. Everything here will not change because of her interaction, and she can't feel anything from the world's feedback to her except vision

She didn't remember whether she could feel pain when she was dreaming.

Most people don't pay attention to this kind of thing.

At least now, only when she speaks, can she perceive from the touch between lips and teeth that her mouth and throat belong to her, not like hands and feet. You have to confirm them with your eyes to perceive their existence.

Confused by this strange feeling, she tried to open her mouth and asked.

"Can you see my side?"

"Of course, I can see. I can even see you talking in bed. When the data output by the host computer is applied to your brain through a neural modem, I will also receive a corresponding message. This message is processed by the graphics card, and similar graphics can also be displayed on the screen Of course, after all, the pictures I see are made up of pixels, which is definitely not as high-definition as you see now. "

"Indeed I was just thinking that the details are too realistic. "

Squatting down, looking at the thin, firm blue grass, Chen Yushan carefully observed its details.

If she concentrated on it, she could even see the light blue lines on the grass.

This can no longer be described as realistic.

The word lifelike is an insult to it.

It's like a world.

A living, new world!

……

"How do you feel?"

Looking at the student sister who wakes up after the experience, standing beside the boat and asking, he handed her a cup of hot water.

“…… Incredible experience, I can't describe the shock in my heart, in a word, it's very amazing. You have tried it yourself. You should be able to understand the feeling in my heart. "

He took off his helmet and thanked Chen Yushan for her hot water in her hands. She recalled the strange world before. For a while, she felt reluctant.

After a pause, she continued.

"I've always wanted to travel around the world I feel that with this thing, let alone travel around the world, even the other world can go. "

Like land boat, she also gave up a lot of things after choosing a lifelong career. If it was before, she often carried her luggage on her back and went on a journey, but now it has almost become a beautiful ideal.Don't say there's no time.

As the CEO of starsky technology, those commercial and even non-commercial secrets she has come into contact with are not safe if she goes around casually.

This technology is quite attractive to her.

Hearing this interesting idea, Lu Zhou said with a smile.

"I'm afraid it's a little difficult. Most virtual entities actually borrow the impression from your own memory and use the fuzzy operation of your brain Popular point is realized by brain supplement. The more complex the scene, the more difficult it is to build. If it's just a grassland, I just need to set a few limited parameters such as color, shape, etc. But if you want to restore Shangjing in virtual reality I'm afraid we have to develop a special modeling tool specifically for this virtual reality system to deeply tap the potential of this system. "

In short, if the whole set of equipment is applied to the PC settings, the neural modulator and demodulator may play the same role as the CPU, while the video card is directly acted by the part of the brain responsible for generating images.

The problem is that the way human brain processes images and the computer graphics card are based on two completely different principles.

Among them, the most outstanding embodiment is that the general chip adopts logic operation, and the data processing is accurate and linear. The brain uses fuzzy operation, which is not accurate and nonlinear for information processing.

And it is this characteristic that determines that the compilation of programs for the brain and for the video card are two different, or even large, ways of compiling.

For example, if you want to build a scene through this virtual reality system, you don't need to draw every detail of the whole scene with a brush. You just need to set a grassland programmatically. There are many grasses on the grassland. They are blue, how high they are, or in other words, what kind of grass they are like, you can complete the whole scene. And this Scenes can be easily "read" by most of the brain.

Just like Chen Yushan's virtual entity in immersion, she can even see the lines on the grass leaves.

After all, most people have seen what the grass looks like. Even if they haven't seen the grassland in reality, they have seen it more or less in film and television works or Internet pictures.

However, if there is not only grass but also a house on the grassland, he must try his best to describe what the house looks like, whether it's a luxury house or a small dilapidated house, a few windows and doors, etc. Moreover, he can't use the general description of "a villa like a professor's villa in Zhongshan International"

after all, we have seen lawn, but Lu Zhou His villa, in addition to his relatives, friends and neighbors, is only seen by himself.

The most interesting thing about this technology is that, according to the difference of information settings, even the same piece of data, after the fuzzy processing of different brains, the images presented in different people's "eyes" may be slightly different.

But there is also a problem.

That's how to use procedural language to "completely" describe something that no one has ever seen, and to minimize the error in accuracy.

After all, the greatest significance of the Internet is the transmission and exchange of information.

If everyone sees what they want to see, not what it should be - or what developers want it to look like, then the meaning of the Internet doesn't exist.

And this set of equipment has become a toy that can only be used for self entertainment.

Chen Yushan: "that is to say, I can only go where I have been?"

Lu Zhou: "not necessarily, the pieces stored in your memory are much larger than you think. Even things you haven't seen can be presented through complete settings It's just that it's going to be very difficult. Just like I described a person's appearance with you, even if I said it in more detail, I would not give you a picture to know him, even if I passed you by, it would be difficult to recognize him in the street. "

Chen Yushan could not help but write a trace of regret on her face.

"It turns out That's a pity. "

Lu Zhou nodded his head: "well, this thing is just a prototype."

"Not only the problem I just mentioned, including the simulation of a series of signals such as hearing, smell, taste and touch, has not been completed. You should also notice that when you enter the immersion mode, the sounds you hear are all from the outside world, and when you speak, they are also made directly through the vocal cords. "

Chen Yushan nodded.

"Indeed If I can't see my hands, I can't even feel my existence in that virtual world. "

"That's the problem that hasn't been solved yet," Lu said, nodding his head. "For the time being, I can only simulate the visual signal. The sound still depends on the headset, and the sense of touch has no solution for the time being. Not only these, including the entire virtual reality system, and even the most critical neural signal modem architecture, many things are not processed well, which takes time. "But even though there are many shortcomings, this device is still quite powerful compared with the traditional "vision Department" VR device.

At least, don't worry about motion sickness or eye injury.

And from the perspective of image quality, it is much more efficient to present the image directly in the brain than to present it in front of human eyes through the screen, and then transmit it to the brain through the retina and visual nerve.

The most ideal situation is to let users forget their body in reality, without worrying about what their hands are doing at the moment, just like a dream, completely immersed in the virtual world, just need to focus on the "immediate" things.

After all, as one of the VR concept founders said, no matter how advanced the imaging technology is, the ideal hardware to create a new reality is not an external head display, but "a chip in the brain", or something similar.

"Let's not talk about these technical problems," said the boat with a smile after a pause. "Well, I didn't cheat you, did I?"

Chen Yushan was slightly stunned, then smiled and said, "it's true If I take it back, it's really a disruptive technology. I even have a hunch that it will change not only the concept of VR, but also people's understanding of network interaction. "

Lu Zhou nodded his head and said, "I think so, too."

Soon the world will enter the 5g era. With the increase of Internet speed by an order of magnitude, what has changed is not only the download speed of users of sand sculpture, but also the operation ecology of the whole Internet.

People will rely on the Internet more frequently, even connecting WiFi or Bluetooth to toilets and pools. In such a big era, the breakthrough of virtual reality technology will bring subversive changes to the whole Internet Ecology.

Also think of this, Chen Yushan's eyes write a trace of obvious excitement, tone full of expectation said.

"Is there anything I need to do?"

After thinking for a while, Lu Zhou said, "actually No. "

Chen Yushan: "...?"

Looking at the expression on Xuejie's face, Lu Zhou is a little embarrassed.

Of course, he didn't say that he just called her here to "share the joy of success", so he coughed softly.

"After all, you can see that this technology is not perfect However, if you want to help me, you can help me find a way to get some experimenters to come here, or directly put the experimental model to the market. After all, I also need to improve the whole research through the data fed back by the experimenters. "

Of course, this thing is not cheap after all. If the land boat is not sure to be sold, can ordinary people afford it.

He is more inclined to the former.

If someone wants to be a mouse, his research will be much better.

As soon as she heard about the demand of the land boat, Chen Yushan immediately asked, "what is the cost of the whole set of equipment?"

Lu Zhou thought for a moment and said, "it's not good to say mass production, but this one It's probably over 100000. "

Chen Yushan took a breath of cool air.

It's not because it's too expensive.

It's because

"I dare say that if one hundred thousand It's going to sell like crazy. "
