Lying on the bed honestly with a helmet, Chen Yushan obediently followed Lu Zhou's instructions to empty her brain, did not make a fuss, and did not think nonsense.

Gradually, a hint of sleepiness began to well-rise in my heart.

Just when she couldn't help but yawn, thinking that she was going to fall asleep soon, there was a prickly feeling on the back of her neck like she had been bitten by an ant.

In an instant, something unexpected happened.

The darkness that had been imprisoned around her vision seemed to have been shattered by a rainbow, and in an instant it was shattered into fragments and scattered outward.

was shocked by the special effects of this scene, and just when Chen Yushan was stunned, the darkness around her had been completely dispelled.

As if she had been reborn from a cocoon, she saw the light source again, and she was already in a blue grassland.

Yes, this grassland is blue.

And the sky was burning red.

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

There is no sense of touch.

But she could really feel the hand on her face.

"Where's the helmet?"

It's gone!?

Groping with his hands on his face incredibly, Chen Yushan's expression became more and more surprised, her pupils shook with disbelief color, and she muttered to herself, "Am I asleep?" ”

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

"It's not wrong to say that you're asleep, and the original principle of this device is also a kind of interference similar to dreams. Of course, this is still a little different from the normal state when we dream, and it is more like an imagination that is actively stimulated by nerve electrical signals...... Forget it, it's cumbersome to explain in layman's language, so you might as well simply understand that you're dreaming. ”

The voice seemed to come from out of this world, yet so close to where she was.

Chen Yushan looked around and tried to stomp her foot.

As expected, no sound came out, not even the soles of the feet on the ground, and there was no sensation.

It's a strange feeling, as if your body doesn't belong to you, just borrowing "her" to peek into the world. Nothing here will change because of her interactions, and she won't feel anything from the world except for her visuals......

She couldn't remember if she could feel pain when she dreamed before.

This kind of thing is something that most people don't even bother to pay attention to.

At least for now, it was only when she spoke that she could perceive from the touch between her lips and teeth that her mouth and throat belonged to her, not like her hands and feet, and she had to confirm them with her eyes to perceive their existence.

Confused by the strange sensation, she tried to open her mouth and asked.

"Can you see what's going on on my side?"

"Of course, I can even see you talking while you're lying on the bed. When the data output by the host computer is applied to your brain through the neural modem, I will also receive a corresponding message. This message is processed by the graphics card to render a similar graphic on the screen as well...... Of course, after all, the images I see are made up of pixels, and they are certainly not as high-definition as what you see now. ”

"Indeed...... I was just thinking that this detail is too realistic. ”

Squatting down and looking at the slender and firm blue grass like the wheat king, Chen Yushan carefully observed its details.

If she looked closely, she could even see rows of pale blue veins on the grass.

This can no longer be described as realistic.

The word verisimilitude is simply an insult to it.

It's like a world here.

A living, new world!

……

"How does it feel?"

Looking at the senior sister who woke up after the experience, Lu Zhou, who was standing next to her, asked while handing it a cup of hot water.

“…… It's an incredible experience, I can't describe the shock in my heart, all in all, it's very, very amazing. If you've tried it yourself, you should be able to understand the feeling in my heart. ”

Chen Yushan, who took off her helmet and thanked Lu Zhou, held the hot water in her hand, recalling the strange world before, and felt reluctant for a while.

After a pause, she continued.

"I've always wanted to travel the world...... I feel that with this thing, not to mention traveling around the world, I can even go to another world. ”

Like Lu Zhou, after choosing a lifelong career, she also gave up many things. In the past, she used to pack her bags and go on a trip, but now it's almost a beautiful ideal.

Don't say if you have time.

With her current status as the CEO of Star Technology, and the commercial and even non-commercial secrets she has access to, it is not very safe to walk around.

This technique is still quite tempting to her. Confusing.

Hearing this interesting idea, Lu Zhou smiled and said.

"That's a bit difficult, I'm afraid, most virtual entities are actually borrowing impressions from your own memory bank, through the fuzzy operation of the brain...... The popular point is achieved with the help of brain supplements. The more complex the scene, the more difficult it is to build. If it's just a grassland, I only need to set a few limited parameters such as color and shape. But if you want to restore the original appearance of Shangjing City in virtual reality...... I'm afraid we will have to develop a special modeling tool specifically for this virtual reality system to dig deeper into the potential of this system. ”

In short, if you apply the whole device to the PC settings, the neural demodulator probably plays a similar role to the CPU, and the graphics card is directly responsible for the part of the brain that is responsible for generating the images.

The problem lies in the fact that the way the human brain processes images and the graphics card of a computer are fundamentally based on two completely different principles.

One of the most prominent manifestations is that the general chip uses logical operations, and the processing of data is accurate and linear. The brain, on the other hand, uses fuzzy operations, and the processing of information is non-precise and non-linear.

And it is precisely this characteristic that determines that the program compiled for the brain and the program compiled for the graphics card are two completely different, even very different ideas.

For a popular example, if you want to build a scene through this virtual reality system, he doesn't need to draw every detail of the whole scene with a brush, he only needs to procedurally set a grassland, there are a lot of grasses on the grassland, they are blue, how tall they are, or even in other words, what kind of grass they look like, the whole scene can be built, and the scene can be easily "read" by most brains.

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

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

However, if there is not only grass on this grassland, but also a house, he must dig out his mind to describe what this house looks like, whether it is a mansion or a small dilapidated house, a few windows and doors, etc., and he cannot use a general description of "like the villa of a professor in Zhongshan International".

After all, everyone has seen such things as lawns, and Lu Zhou's own villa, except for his relatives, friends and neighbors, is only seen by himself.

The most interesting thing about this technology is that according to the difference in information settings, even the same piece of data, after being fuzzy by different brains, may present a scene in the "eyes" of different people, there may be subtle differences.

But from this, this also creates a problem.

That is how to describe something in procedural language that no one has ever seen before, and to minimize the error in this accuracy.

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 what it should be – or what developers want it to be, then the Internet doesn't make sense.

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

Chen Yushan: "In other words, I can only go where I've been?" ”

Lu Zhou: "Not necessarily, the fragments stored in your memory bank are probably much larger than you imagined, even if you haven't seen something, it can be presented through a complete setting...... It's just that this makes the job difficult. Just like when I describe a person's appearance to you, even if I say it in detail, if I don't give you a photo, it will be difficult for you to recognize him on the street, even if you pass by. ”

Chen Yushan couldn't help but have a trace of regret written on her face.

"I see...... That's a shame. ”

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

"It's not just the problem I just mentioned, but the simulation of a series of signals such as hearing, smell, taste, touch, etc., is not yet complete. You should have also noticed that when you enter the immersion mode, the voices you hear are all coming from the outside world, and when you speak, you also speak directly through your vocal cords. ”

Chen Yushan nodded.

"That's true...... If I hadn't been able to see my hands, I wouldn't even feel my presence in that virtual world. ”

"This is the difficulty that this technology has not yet solved," Lu Zhou nodded, and continued, "For the time being, I can only simulate visual signals, and the sound still has to rely on the headset, and the sense of touch is not solved for the time being." Not only that, but the entire virtual reality system, and even the architecture of the most critical neural modem, a lot of things have not been processed perfectly, and these things will take time. ”

However, even if there are many shortcomings, this set of equipment is still quite awesome compared to the traditional "visual kei" VR equipment.

At the very least, you don't have to worry about "motion sickness" and you don't have to worry about hurting your eyes.

And from the perspective of image quality, it is far more efficient to present the image directly in the brain than to present it in front of people's eyes through the screen, and then transmit it to the brain through the retina and optic nerve.

Ideally, users can forget about their bodies in reality, without worrying about what their hands are doing at the moment, and fully immerse themselves in the virtual world as if they were in a dream, focusing only on what is happening "in front of them".

After all, as one VR concept pioneer put it, no matter how advanced imaging technology is, the ideal hardware to create a new reality is not an external headset, but "a chip in the brain," or something like that.

"Putting these technical issues aside," Lu Zhou paused for a moment, then suddenly smiled and said, "Well, I didn't lie to you, right?" ”

Chen Yushan was slightly stunned, and then said, "Indeed...... I take back what I said earlier, this is indeed a disruptive technology. I even have a hunch that it will change not only the concept of VR, but even the way people understand how they interact online. ”

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

Soon the world will enter the 5G era, and with the increase in network speed by an order of magnitude, it is not only the download speed of sand sculpture netizens that will change, but also the entire Internet operation ecology.

People will rely on the Internet more often, and even connect to WiFi or Bluetooth on toilets and pools. In such a big era, the breakthrough of virtual reality technology will surely bring subversive changes to the entire Internet ecology.

Also thinking of this, Chen Yushan's eyes had a hint of obvious excitement written on it, and her tone was full of anticipation.

"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 senior sister's face, Lu Zhou was a little embarrassed.

Of course, he couldn't say that he had only called her here to "share the joy of success", so he coughed lightly.

"After all, you also see that the technology is not perfect...... But if you are willing to help, you can help me find a way, get a few experimenters over, or directly bring the experimental model to the market, I have no objection, 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, and Lu Zhou is not sure if ordinary people can afford it if he really wants to sell it.

In contrast, he still prefers the former.

If someone were willing to be a guinea pig for him, his research would go much better.

As soon as she heard Lu Zhou's needs, Chen Yushan immediately asked, "How much does the whole equipment cost?" ”

Lu Zhou thought for a while and said, "It's not good to say mass production, but this one...... That's about 100,000. ”

Chen Yushan gasped.

Not because it's too expensive.

It's because ......

"I dare say that if 100,000 units...... This thing is going to sell like crazy. ”
