Chapter 1068 A Living World!

Honestly laying on the bed with the helmet on, Chen Yushan obediently followed Lu Zhou's instructions and emptied her mind, without fussing or thinking about it.

Gradually, a trace of drowsiness began to well up in my heart.

Just when she couldn't help yawning, thinking that she was going to fall asleep soon, she felt a prickling sensation on the back of her neck, as if she had been bitten by an ant.

Immediately after that, something unexpected happened to her.

The darkness imprisoned around her field of vision, like being shattered by a rainbow, instantly turned into fragments and spread outward.

Surprised by the special effects of this scene, just as Chen Yushan was in a daze, the darkness surrounding her was completely dispelled.

As if 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 is burning red.

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

There is no touch.

But she could really feel that this hand was on her face.

"Where's the helmet?"

gone! ?

With her hands groping her face in disbelief, Chen Yushan's expression became more and more surprised, her pupils flickered with unbelievable colors, and she muttered to herself, "Did I fall asleep?"

Just when she was hesitating whether to bite herself to confirm this, a familiar voice rang in her ear.

"It's not wrong to say that you fell asleep. The principle of this set of equipment is also a kind of interference with dreams. Of course, this is still somewhat different from the state when we dream under normal circumstances. In comparison, it is more It's like a kind of imagination that is actively induced by the stimulation of nerve electrical signals... Forget it, it is very troublesome to explain in ordinary language, you should just understand it as a dream."

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

Chen Yushan looked around and tried to stamp her feet.

As expected, there was no sound, and even the soles of the feet on the ground did not feel any sensation.

This feeling is very strange, as if my body does not belong to me, I just use "her" perspective to spy on this world. Everything here will not change because of her interaction, and she will not feel any feedback from this world to her except for vision at all...

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

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

At least for now, only when she speaks, can she feel from the touch between her lips and teeth that her mouth and throat belong to her, unlike her hands and feet, which must be confirmed with her eyes to perceive to their existence.

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

"Can you see what's going on here?"

"Of course I can see it. I can even see you lying on the bed talking. When the data output by the host computer is applied to your brain through the neural modem, I will also receive a corresponding message here. This paragraph After the information is processed by the graphics card, similar graphics can also be presented on the screen...Of course, after all, the pictures I see are all composed of pixels, and they are definitely not as high-definition as what you see now."

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

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

If she concentrated her attention, she could even see rows of light blue veins on the grass.

This can no longer be described as realistic.

The word realistic is an insult to it.

It's like a whole world here.

A living, brand new world!

...

"How does it feel?"

Seeing the senior sister who woke up after finishing the experience, Lu Zhou, who was standing beside her, asked and handed her a cup of hot water.

"...It's an incredible experience. I can't describe the shock in my heart. In short, it's very, very amazing. Try it yourself, and you should understand the feeling in my heart."

Chen Yushan took off her helmet and thanked Lu Zhou, holding hot water in her hand, recalling the grotesque world before, feeling reluctant to part for a while.

After a pause, she continued.

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

Like Lu Zhou, after choosing a lifelong career, she also gave up many things. If it was before, she would often pack her bags and take a casual trip, but now it has almost become a beautiful ideal.

Don't tell me you have time.

With her current status as the CEO of Xingkong Technology, and the commercial and even non-commercial secrets she has come into contact with, it is not safe to walk around casually.

This technique is quite tempting to her.

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 bank, and through the fuzzy calculation of the brain... the popular point is to use brain supplementation to realize it. The more complex the scene, the more difficult it is to construct. .If it’s just a piece of 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 in virtual reality... I’m afraid we have to specialize in this It is necessary to develop a virtual reality system, develop specialized modeling tools, and deeply explore the potential of this system.”

In short, if you apply the entire setup to a PC, the neural modem would presumably play the same role as the CPU, while the graphics card would be the part of the brain responsible for generating images.

The problem is precisely here, the way the human brain processes images and the graphics card of the computer are fundamentally based on two completely different principles.

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

And it is precisely this characteristic that determines that the programs compiled for the brain and the programs compiled for the graphics card are two completely different, or even completely different, ideas in terms of compilation ideas.

To give a popular example, if he wants to build a scene through this virtual reality system, he does not need to draw every detail of the whole scene with a brush, but only needs to programmatically set a grassland, and there are many Grass, they are blue, how tall they are, or even what kind of grass they look like in other words, can complete the construction of the entire scene, and this scene can be easily "read" by most brains.

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

After all, the vast majority of people have seen what grass looks like. Even if they haven’t seen grasslands in reality, they have more or less seen them 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 has to rack his brains to describe what the house looks like, whether it is a mansion or a small shabby house, how many windows and doors, etc. Using a general description like "a villa of a certain professor in Zhongshan International",

After all, everyone has seen things like lawns, and Lu Zhou's own villa, apart from his relatives, friends and neighbors, has only been 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 may be slightly different in the "eyes" of different people after being blurred by different brains.

But from this, a problem was born.

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

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 the thing should be presented—or the way the developer wants it to be presented, then the meaning of the Internet will not 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 fragments stored in your memory bank are probably much larger than you imagined. Even things you have never seen before can be presented through complete settings... But, This will bring huge difficulties to the work. Just like I describe a person’s appearance to you, even if I describe it in detail, without giving you a photo to recognize him, even if you pass by, it will be difficult for you to recognize him on the street. recognize."

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

"So that's how it is...that's a pity."

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

"It's not just the problem I just mentioned, including the simulation of a series of signals such as hearing, smell, taste and touch, which have not yet been completed. You should have noticed that after entering the immersive mode, the sounds you hear It comes from the outside world, and it is also directly produced through the vocal cords when speaking."

Chen Yushan nodded.

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

"This is the unsolved difficulty of this technology," Lu Zhou nodded, and continued, "Temporarily speaking, I can only simulate the visual signal, and the sound has to rely on the headset, and the tactile sense is temporarily unsolvable. Not only These, including the entire virtual reality system, and even the most critical neural signal modem architecture, many things have not been perfected, and it will take time."

But even with many shortcomings, this set of equipment is still quite awesome compared to traditional "visual system" VR equipment.

At 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 images directly in the brain than to present them in front of people's eyes through a screen, and then transmit them to the brain through the retina and optic nerve.

The ideal situation is to allow users to forget about their bodies in reality, without having to worry about what their hands are doing at the moment, and fully immerse themselves in the virtual world as if they were dreaming, and only need to focus on what is happening "in front of them" matter.

After all, as one pioneer of the VR concept put it, no matter how advanced the imaging technology, the ideal hardware for creating a new reality is not an external headset, but "a chip in the brain", or something similar thing.

"Aside from these technical issues," Lu Zhou paused for a moment, then suddenly said with a smile, "How about it, I didn't lie to you, did I?"

Chen Yushan was slightly stunned, and then said with a smile: "Indeed... I take back what I said earlier, this is indeed a subversive technology. I even have a hunch that it will not only change the concept of VR, but even the concept of VR. people’s understanding of network interactions.”

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

Soon the world will enter the 5G era. As the network speed increases by an order of magnitude, not only the download speed of sand sculpture netizens will change, but also the entire operating ecology of the Internet.

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

Thinking of this as well, Chen Yushan's eyes were clearly filled with excitement, and she said in a tone full of expectation.

"Is there anything I can 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 felt a little embarrassed.

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

"After all, you have also seen that this 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 push the experimental model to the market. I have no objection. After all, I also need the data fed back by the experimenters to improve the whole research.”

Of course, this thing is not cheap after all, Lu Zhou is not sure if he really wants to sell it, whether ordinary people can afford it.

In contrast, he still prefers the former.

If someone is willing to be a guinea pig for him, his research will go much smoother.

Upon hearing Lu Zhou's request, Chen Yushan immediately asked, "How much does the whole set of equipment cost?"

Lu Zhou thought for a while and said, "Mass production is hard to say, but for this machine... it's probably more than 100,000."

Chen Yushan gasped.

Not because it's too expensive.

but because...

"I dare say, if one hundred thousand units... this thing will definitely sell like crazy."
