Honestly lying in bed with a helmet, Chen Yushan obediently vented the brain according to Lu Zhou's instructions, no noisy, no more cranky.

Gradually, a little sleep began to come to my heart.

Just as she couldn't help but yawn, thinking that when she didn't hurry to start falling asleep, there was a feeling of puncturing that was bitten by the ants.

Immediately afterwards, something unexpected happened to her.

The darkness that was confined around her sight, as if it had been shattered by a rainbow, instantly turned into fragmented pieces and spread out to the outside.

I was shocked by the special effects of this scene. When Chen Yushan was screaming at the gods, the darkness around him was completely dispelled.

Like the rebirth, she re-visited the light source and was already in the blue grassland.

Yes, this grassland is blue.

The sky is burning red.

Standing in this grotesque world, Chen Yushan raised his right hand in an incredible face and touched his cheek.

There is no touch.

But she really felt that this hand was on her face.

"What about helmets?"

Missed! ?

The hands were groping on his face in an incredible way. Chen Yushan’s expression became more and more astonished. The color in the pupil was shaking and he couldn’t believe it. He whispered to himself, “Is I asleep?”

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

"It is true that it is asleep. The principle of this device is also a kind of interference similar to the dream. Of course, this is different from the state when we dreamed. In contrast, it is more It is like an imaginary evoked by the stimulation of nerve electrical signals... Well, it is very troublesome to explain in plain language, you still simply understand that you are dreaming."

The voice seems to come from outside the world, but it is so close to her current position.

Chen Yushan looked around and tried to squat.

Unexpectedly, no sound was emitted, and even the soles of the feet on the ground did not have any consciousness.

This feeling is very strange, just like your body is not your own, just borrowing the perspective of "her" to spy on the world. Everything here will not change because of her interaction. She also does not feel anything other than vision, everything from the world to her feedback...

She doesn't remember when she was dreaming, can she feel the pain.

This kind of thing wants to come to the vast majority of people will not deliberately pay attention.

At least for now, only when she speaks, can she feel from the touch between her lips and her teeth that her mouth and throat are her own, not like her hands and feet, she must use her eyes to confirm and perceive. To their existence.

There was a bit of confusion about this strange feeling. She tried to open her mouth and asked.

"Can you see the situation on my side?"

"Of course I can see that I can even see you lying in bed. The data output by the host is also sent to your brain through the neural modem. I will also receive a corresponding message. The message is processed by the graphics card, and similar graphics can be rendered on the screen... Of course, after all, the images I see are composed of pixels, and certainly not the HD you see now."

"Really... I was still thinking, this detail is too realistic."

He leaned down and looked at the blue grass that was as thin and firm as the wheat king, and Chen Yushan carefully observed the details.

If she concentrates on seeing it, she can even see a light blue texture on the grass.

This can no longer be described as realistic.

The word realistic is simply an insult to it.

It is like a world here.

A living, new world!

......

"how are you feeling?"

Looking at the sister who woke up at the end of the experience, I asked the side of the boat and asked for a cup of hot water.

"...the incredible experience, I can't describe the shock in my heart. In short, it is very, very amazing. You have tried it yourself, you should be able to understand the feeling in my heart."

I still haven't tried to take off my helmet. Chen Yushan, who is thankful to Lu Zhoudao, holds hot water in her hands. She recalls the previous grotesque world. For a time, there was a sense of reluctance.

Suddenly, she continued.

"I always wanted to travel around the world... I feel that after I have this thing, let alone travel around the world, and even the world can go."

Like Lu Zhou, after choosing a lifelong career, she also gave up a lot of things. If it was before, she often carried her bag up and went on a trip to go, but now it has become a beautiful ideal.

Don't say there is no time.

In the capacity of her current star technology ceo, and the commercial and non-commercial secrets that she is exposed to, it is not safe to go casually.

This technique is quite tempting and confusing for her.

Upon hearing this interesting idea, Lu Zhou smiled and said.

"That's probably a little difficult. Most virtual entities actually borrow the impressions in your own memory, through the fuzzy operations of the brain... The popular point is achieved by means of brain supplementation. The more complicated the scene, the more difficult it is to build. If it's just a piece of grassland, I only need to set a few limited parameters such as color, shape, etc. But if you want to restore the original appearance of Shangjing in virtual reality...we probably have to specifically target this Set up a virtual reality system, develop specialized modeling tools, and dig deep into the potential of this system."

In short, if the entire device is set to the PC settings, the neuromodulation demodulator will play a role similar to cpu, and the graphics card will be directly served by the part of the brain responsible for generating images.

The problem is precisely here, the way the human brain processes the image, and the computer's graphics card from the root, is based on two completely different principles.

The most prominent manifestation is that the general chip uses logical operations, and the processing of the data is accurate and linear. The brain uses fuzzy operations, and the processing of information is inexact and non-linear.

It is this characteristic that determines the program for brain compilation and the program for video card compilation. In the compilation idea, there are two very different and even different approaches.

To give a popular example, if you want to build a scene through this virtual reality system, you don't need to paint every detail of the whole scene with a brush. You only need to programmatically set a grassland. There are many grasslands. Grass, they are blue, about how high, or even in other words, which grass can complete the construction of the entire scene, and this scene can be easily "read" by most brains.

Just like the virtual entity Chen Yushan saw in the immersive state, he could even see the lines on the blades of grass.

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 the pictures of the film or television or the Internet.

However, if there is not only a grass on the grassland, but also a house, he must dig into it to describe what the house looks like, whether it is a mansion or a small broken house, a few windows, a few doors, etc., but still can not Using the general description of "a villa like a professor at Zhongshan International",

After all, the lawn has been seen by everyone, and Lu Zhou’s own villa, except his neighbors and relatives, has only seen it himself.

The most interesting part of this technology is that, depending on the difference in information settings, even the same piece of data, through the different processes of the brain, the scenes that appear in different people's "eyes" may be subtle.

But this also gave birth to a problem.

That is how to use a procedural language to "completely" describe something that no one has ever seen, and to minimize this precision error.

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

If everyone sees what they want to see, rather than the thing that should have been presented or what the developer wants it to appear, then the meaning of the Internet does not exist.

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

Chen Yushan: "That is, I can only go where I have been?"

Lu Zhou: "Not necessarily, the debris stored in your memory is probably much larger than you think. Even things you haven't seen can be presented through complete settings... just, This will bring a lot of work difficulty. Just like I describe the appearance of a person with you, even if I say it in detail, I will not give you a photo, even if you pass by, it will be difficult for him to be on the street. recognize."

Chen Yushan could not help but write a regret.

"It turned out to be like that... that's a pity."

Lu Zhou nodded: "Well, this thing is just a prototype."

"Not just the problem I just said, including the simulation of a series of signals, such as hearing, smell, taste and touch, etc., has not been completed yet. You should also notice that after you enter the immersive mode, the sounds you hear are all From the outside world, when you speak, you also speak directly through the vocal cords."

Chen Yushan nodded.

"It's true... If you can't see your own hands, I can't even feel my existence in that virtual world."

"This is the difficult point that this technology has not yet solved," Lu Zhou nodded and continued. "For the time being, I can only do simulations of visual signals. The sound has to rely on the headset, and the touch is temporarily unsolvable. Not just These, including the entire virtual reality system, and even the most critical neural signal modem architecture, many things are not handled well, which takes time."

But even if there are many deficiencies, this device is quite powerful compared to the traditional "visual system" vr device.

At least, don't worry about "motion sickness", don't worry about hurting your eyes.

Moreover, from the perspective of image quality, it is much more efficient to present images directly in the brain than to be presented to the human eye through the screen and then transmitted to the brain through the retina and visual nerves.

The ideal situation is to let the user forget his own body in reality, without having to worry about what his hands are doing at the moment, just like being completely immersed in the virtual world as a dream, just focus on what happens in front of the eyes. thing.

After all, as a vr concept pioneer said, no matter how advanced imaging technology, the ideal hardware to create a new reality is not an external head, but a "chip in the brain", or similar. thing.

"Don't talk about these technical issues," Lu Zhou paused for a moment, suddenly said with a smile, "How, I didn't lie to you?"

Chen Yushan squatted slightly, and then she said, "Really... I retracted the previous words. This is indeed a subversive technique. I even have a hunch that it will change not only the concept of vr, but even change. People understand the interaction of the network."

Lu Zhou clicked and said, "I think so too."

Soon the world will enter the 5G era. As the speed of the Internet increases by an order of magnitude, it is not just the download speed of the sand sculpture users, but the change will be the operating ecology of the entire Internet.

People will rely more on the Internet more frequently, even connecting wifi or Bluetooth to the toilet and pool. In such a big era, the breakthrough of virtual reality technology will surely bring subversive changes to the entire Internet ecosystem.

I also thought of this point. Chen Yushan’s eyes were filled with a hint of excitement, and the tone was full of expectations.

“Is there anything I need to do?”

Lu Zhou thought for a while and said: "Actually... no."

Chen Yushan: "...?"

Looking at the expression on the sister's face, Lu Zhou was a little embarrassed.

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

"After all, you have seen that this technology is still not perfect... But if you are willing to help, you can help me think about it, get a few experimenters, or directly push the experimental model to the market. I don't object. After all, I also need to improve the entire study through the data fed back by the experimenter."

Of course, this stuff is not cheap after all. If Lu Zhou is not sure if he wants to sell it, most people can afford it.

In contrast, he is more inclined to the former.

If someone is willing to give him a mouse, his research will be much smoother.

Upon hearing the demand of Lu Zhou, Chen Yushan immediately asked: "What is the cost of the whole set of equipment?"

Lu Zhou thought about it and said: "The mass production is not good, but the words of this station... it is probably more than 100,000."

Chen Yushan took a cold breath.

Not because it is too expensive.

But because...

"I dare say that if it is 100,000 units... this stuff will definitely sell crazy."
