Chen Yushan obediently laid on the bed with the helmet on. She obediently followed Lu Zhou's instructions and emptied her mind. She didn't make a fuss and didn't think about anything else.
Gradually, a trace of sleepiness began to fill her mind.
Just when she couldn't help but yawn and think that she was going to fall asleep if she didn't start soon, she felt a tingling sensation on the back of her neck like she was bitten by an ant.
In the next instant, something unexpected happened.
The darkness that imprisoned her vision seemed to have been shattered by a rainbow. In an instant, it turned into fragmented fragments and scattered outwards.
Chen Yushan was shocked by the special effects of this scene. While she was still in a daze, the surrounding darkness had been completely dispelled.
Like a cocoon being reborn, she saw the light source again. She was already in a blue grassland.
Yes, this grassland was blue.
And the sky was burning red.
Standing in this bizarre and dazzling world, Chen Yushan raised her right hand in disbelief and touched her cheek.
She didn't feel anything.
But she did feel that this hand was on her face.
"Where's the helmet?"
Gone?!
Her hands touched her face in disbelief. Chen Yushan's expression became more and more surprised. Her pupils shook with disbelief, and she whispered to herself, "Am I asleep?"
Just as she was hesitating whether to bite herself to confirm this point, a familiar voice rang in her ears.
"It's actually not wrong to say that you are asleep. The principle of this device is similar to interference in dreams. Of course, this is still a little different from the state when we dream. In contrast, it is more like an imagination that is actively induced by nerve electrical signals … Forget it, it's troublesome to explain it in layman's language. You should just think of it as a dream. "
The voice seemed to come from outside the world, but it was so close to her current position.
Chen Yushan looked around and tried to stomp her feet.
As expected, there was no sound. Even the soles of her feet on the ground didn't feel anything.
This feeling was very strange. It was as if her body didn't belong to her, and she was only using "her" perspective to spy on this world. Nothing here would change because of her interaction, and she could not feel any feedback from this world other than her vision …
She couldn't remember if she could feel pain in her dreams before.
Most people probably wouldn't pay attention to such things.
At least for now, only when she opened her mouth to speak could she feel that her mouth and throat belonged to her. Unlike her hands and feet, she had to use her eyes to confirm 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. I can even see you lying on the bed talking. When the data output by the mainframe is sent to your brain through the neural modem, I will also receive a corresponding message on my side. This piece of information is processed by the graphics card and can also be displayed on the screen … Of course, after all, the image I see is composed of pixels, so it's definitely not as high-definition as what you see now. "
"Indeed … I was just thinking that the details are too realistic."
Squatting down, Chen Yushan looked at the blue grass that was as fine and straight as wheat awns. She carefully observed its details.
If she concentrated, she could even see lines of light blue veins on the blade of grass.
This couldn't be described as realistic anymore.
The word "realistic" was an insult to it.
This is like a world.
A living, brand-new world!
…
"How do you feel?"
Lu Zhou looked at Chen Yushan, who woke up after the experience ended. He stood next to her and handed her a cup of hot water.
"… Incredible experience, I can't describe the shock in my heart, it's very, very amazing. You tried it yourself, you should be able to understand the feeling in my heart. "
Chen Yushan reluctantly took off her helmet and thanked Lu Zhou. She held a cup of hot water in her hand and recalled the previous strange world. For a while, she felt a sense of reluctance.
She paused for a second and continued.
"I've always wanted to travel around the world … I feel like with this thing, forget about traveling around the world, I can even go to another world."
Just like Lu Zhou, after choosing a lifelong career, she also gave up a lot of things. If it was in the past, she would often carry a backpack and go on a trip. But now, it had almost become a beautiful ideal.
Not to mention that she didn't have time.
She was now the CEO of Star Sky Technology, and she had access to commercial and even non-commercial secrets, so it wasn't safe for her to wander around.
This technology was quite tempting to her.
Lu Zhou smiled and spoke.
"That's a bit difficult. Most virtual entities actually borrow the impression from your own memory bank and use the brain's fuzzy calculations … Basically, it's achieved with your imagination. 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, shape, and so on. But if you want to restore the original appearance of Beijing in virtual reality … I'm afraid we have to specifically develop a modeling tool for this virtual reality system and dig deep into the potential of this system. "
In short, if the whole set was applied to a PC, the neural adjustment demodulator probably played a role similar to the CPU, while the graphics card was directly responsible for generating images in the brain.
The problem was that the way the human brain processed images and the graphics card of a computer were based on two completely different sets of principles.
The most prominent embodiment was that the general chip used logical operations, and the processing of data was accurate and linear. The brain used fuzzy operations, and the processing of information was not accurate and nonlinear.
It was this characteristic that programs compiled for the brain and programs compiled for the graphics card had two completely different approaches to compiling.
For example, if he wanted to build a scene with this virtual reality system, he didn't need to draw every detail of the entire scene with a brush. He only needed to set up a grassland with a lot of grass on the grassland. They were blue, and they were tall. In other words, he could build the entire scene, and this scene could be easily "understood" by most people's brains.
Just like how Chen Yushan could see in the immersive state, she could even clearly see the lines on the grass.
After all, most people had seen what grass looked like. Even if they hadn't seen a grassland in real life, they had more or less seen it in movies and television or on the Internet.
However, if the grassland wasn't just grass, there was also a house. He had to rack his brain to describe what the house looked like, whether it was a mansion or a dilapidated house, how many windows and doors there were, etc. Also, he couldn't use a general description like "a professor's mansion at Zhongshan International".
After all, everyone had seen things like lawns before. Other than his family, friends, and neighbors, only Lu Zhou himself had seen his own mansion.
The most interesting thing about this technology was that, based on the differences in information settings, even the same piece of data could be blurred by different brains and appear in different "eyes" of different people.
However, this also created a problem.
Which was how to use a programming language to "completely" describe something that no one had ever seen before, while minimizing the accuracy of the description.
After all, the biggest significance of the Internet was the transmission and exchange of information.
If everyone saw what they wanted to see, and not what that thing was supposed to look like, or what the developers wanted it to look like, then the Internet would be meaningless.
And this set of equipment had become a toy that could only be used for self-entertainment.
Chen Yushan: "In other words, I can only go to places that I've been to before?"
Lu Zhou: "Not necessarily, the fragments stored in your memory bank are probably much larger than you think. Even if it's something you haven't seen before, it can be displayed through a complete setting … It's just that this will bring a lot of difficulty to the work. It's just like when I describe a person's appearance to you. No matter how detailed I am, if I don't show you a photo, you won't be able to recognize him even if you pass by him on the street. "
Chen Yushan couldn't help but have a look of disappointment on her face.
"I see … That's a shame."
Lu Zhou nodded and said, "Yeah, this is just a prototype."
"Not just the problem I just mentioned, but the simulation of a series of signals such as hearing, smell, taste, and touch hasn't been completed yet. You should have noticed that after you entered immersion mode, the sounds you hear are coming from the outside world. When you speak, you speak directly through your vocal cords. "
Chen Yushan nodded.
"That's right … If I didn't see my hands, I wouldn't even be able to feel my own existence in the virtual world."
"This is the difficulty of this technology." Lu Zhou nodded and said, "For the time being, I can only simulate visual signals. I still have to rely on the headset for sound, and I can't simulate touch for the time being. Not just that, but the entire virtual reality system, even the most important neural signal modem architecture, has yet to be perfected. This will all take time. "
However, even though there were many shortcomings, this set of equipment was still quite nutty compared to traditional "visual" VR equipment.
At the very least, he didn't have to worry about motion sickness or hurting his eyes.
Also, from a picture quality point of view, directly presenting the image to the brain was far more efficient than presenting it to the human eye through a screen, and then transmitting it to the brain through the retina and optic nerves.
The ideal situation was to make the user forget about their body in the real world. They wouldn't have to worry about what their hands were doing at the moment. It would be like they were in a dream, completely immersed in the virtual world, and they would only need to focus on what was happening in front of them.
After all, just like a pioneer of VR said, no matter how advanced the imaging technology was, the ideal hardware to create a new reality was not an external headset, but a "chip in the brain" or something similar.
"Let's not talk about these technical problems." Lu Zhou paused for a second and suddenly smiled. "What do you think, I didn't lie to you, right?"
Chen Yushan paused for a second and said, "You're right … I take back what I said before, this is indeed a disruptive technology. I even have a feeling that it will change not only the concept of VR, but it will also change people's understanding of online interaction. "
Lu Zhou nodded and said, "That's what I think too."
Soon, the world would enter the 5G era. As the internet speed increased by an order of magnitude, not only would the download speed of netizens change, but it would also change the entire Internet ecosystem.
People would rely on the Internet more frequently, and even toilets and sinks would be connected to WiFi or Bluetooth. In this era, a breakthrough in virtual reality technology would definitely bring about disruptive changes to the entire Internet ecosystem.
Chen Yushan also thought of this. There was a trace of obvious excitement in her eyes, and she spoke with a tone full of expectation.
"Is there anything you need me to do?"
Lu Zhou thought for a second and said, "Actually … Not really."
Chen Yushan: "…?"
Lu Zhou looked at Chen Yushan's face and felt a little embarrassed.
Of course, he couldn't say that he called her here just to "share the joy of success", so he coughed and spoke.
"After all, as you can see, this technology is not perfect yet … But if you want to help, you can help me think of a way. You can get a few experimenters here, or you can directly introduce the experimental model to the market. After all, I also need the feedback from the experimenters to improve the entire research."
Of course, this thing wasn't cheap. Lu Zhou wasn't sure if the average person could afford it if he sold it.
He was more inclined to do the former.
If someone was willing to be his lab rat, his research would be much smoother.
When Chen Yushan heard Lu Zhou's request, she immediately asked, "How much does the entire machine cost?"
Lu Zhou thought for a bit and said, "I don't know if it'll be mass produced, but for this one … It'll cost around 100,000 yuan."
Chen Yushan took a deep breath.
It wasn't because it was too expensive.
It was because …
"I dare say, if it's 100,000 yuan per unit … This thing will definitely sell like crazy."
