When the nerve access technology was used to equip Comrade Li Gaoliang with the value of titanium alloy and let him stand up again, the information technology experts of the Institute of Advanced Studies once felt this topic with him.

It's not just the paraplegic patients who have damaged the spinal nerves.

If complex visual signals and auditory signals can be simulated and simulated like action signals, and the device can be directly connected to the neural prosthesis or the brain, it is impossible to let the imaginary neural access that allows consciousness to sneak into the digital world. Virtual reality technology will no longer be an illusion.

At that time, Lu Zhou said that this was indeed an interesting topic, so I could study it, but there were still a lot of more important things waiting for him to do, and this matter was thrown behind him.

Now, coincides with the revolutionary breakthrough in carbon-based chip technology, there is no place for more points on the body. After being reminded by the person named Ye Nan, this matter was re-thinked by Lu Zhou.

Thinking of Willa, who is still lying in the dormant cabin, Lu Zhou feels that if she can't wake her up for a while, she must at least try to do something for her.

Although he is also clear, the hope that this stuff can work on her is quite embarrassing...

After changing clothes, Lu Zhou, sitting in front of the computer, combed the things he had written down.

In short, the core components of the technology can be divided into three modules.

One is the acquisition of neural signals, the other is the processing of neural signals, and finally the simulation of neural signals, that is, the stage of finally feeding back information to the brain.

The technical difficulties of these three core components are sequentially increased in order.

The acquisition of neural signals is very simple. As early as the 1980s, there was already something like the eeg sensor, the so-called EEG sensor. Nowadays, how advanced this technology is, even surpasses the imagination of ordinary people who are not exposed to this technology.

Whether it is the vr system created by Silicon Valley's eyemynd, the user can navigate the virtual world through the idea, or the 16 students of the University of Florida completed the world's first brainwave drone competition, which is the technology. An embodiment of.

As for the second item, the processing of neural signals is more complicated than the acquisition of neural signals.

Although on the surface, this thing is only the computer's ability to process information, but in fact it is a rather complicated procedural problem.

This kind of complexity lies in the fact that humans know little about their own brains. Unless it is a limited situation, visual signals, auditory signals, and olfactory signals are far less irritating to the brain than motion signals.

The desire to distinguish these signals and compile a set of instructions for constructing the virtual reality world, as well as the operating system... and so on, can be categorized in the second.

As for the third item, the electrical signal processed by the neural signal modem is transmitted to the brain, which is the most intuitive presentation of the user experience, and is the most complicated and difficult part of the entire neural access virtual reality technology. .

the reason is simple.

Just as people encounter difficulties in developing the second core component of the technology, how can they output signals that can be read by the brain to the brain if they can't even understand the brain?

At present, the more advanced approach is to implant a neuroprosthesis at the location of the cerebral cortex.

However, for the time being, this technology is mainly used to repair the functional obstacles caused by nerve damage. There is still a long way to go before simulating a series of signals such as visual, auditory, and olfactory.

Currently in this field, in front of the comparison is the Catalonia Institute of Nanoscience and Nanotechnology in Barcelona, ​​Spain. Through the graphene-based materials, the researchers of the institute are designing an electrode to interact with the brain tissue interface. "Nerve interface", as to which step has been specifically studied, only they know it.

In fact, for the third core component, Lu Zhou has a lot of technical reserves.

The "answer" that he redeemed through the points is mainly concentrated on the second part, the debug demodulator of the neural signal.

As for letting the brain read the signal from the modem, he can only do the visual simulation step.

A series of feelings such as hearing and smell, even touch and excitement can only be achieved by external stimulation.

For example, a headset or the like is built into the helmet.

Thinking of this, Lu Zhou still has some regrets.

If you can do a full-scale simulation of all perceptions, you can probably achieve the final form of virtual reality technology.

That is, the whole consciousness is connected to the virtual Internet world, and the second life is obtained in the virtual reality.

Whenever you want to experience and experience skydiving, rock climbing, what you want to do in reality, but you haven't done it, you can do it with paper people for a lifetime.

As for other uses, you can think about it slowly.

It is a pity that his subject level is not enough for the system to answer the questions in the second half of his question. If the points are forcibly exchanged, at least two levels of scientific efficiency will be penalized.

The only thing that made him happy was that at least the system marked the amount of the points, which shows that the problem was solved in his lifetime.

It’s just that it’s more difficult.

Thinking of this, Lu Zhou, sitting in front of the computer, thought for a while.

In the spirit of scholars who are not as happy as the music, he finally selected a theoretical part that was not so advanced and did not involve patents, and compiled a paper.

He did not expect this paper to ignite the revolution of virtual reality technology at once. I just hope that this paper can play a role in inspiring the scholars who are engaged in this field to make more valuable achievements in this field. .

As for the author of the paper...

Considering that the core content is mainly in the fields of computer and biology, Lu Zhou once again put on the vest of Dr. Z.

I thought that I had an Oolong last time and I was almost recognized by my own people. This time he learned it and didn't touch arxiv. Instead, he opened the biologist's pre-printed website biorxiv.

I pondered the process of uploading manuscripts for a while, but when Lu Zhou was ready to hang up the papers, I suddenly felt a sensation.

Wait, if this is thrown on the biorxiv, doesn't it mean that you don't want to make a move?

In the heart of the dark road, a good risk, Lu Zhou turned off the biorxiv website with a black line, and ran the scalp to re-attach the paper to arxiv.

Although biologists who care about arxiv don't have as many biorxivs as above, from another perspective, more and more researchers in mathematics, computer, and physics have joined the research in biology over the years, and they have encountered arxiv. The probability of scholars working on both machine neural networks and biological neural networks should be much higher than that of biorxiv.

Of course, biological neural networks and mechanical neural networks are among the most difficult ones in biology and computer science. It is not an exaggeration to say that scholars who can master both fields at the same time are rare.

In fact, Lu Zhou expects to be able to meet the researchers who are good enough to be like-minded and improve the technology together... It is best to solve the troublesome things for him.

However, in fact, he did not have much hope for this.

The biggest purpose of his paper is to warm up the technology, and when he takes the whole technology out, it doesn't seem too awkward.

After all, if this thing comes out directly, the jump is still a bit big, and the average person may not see it, but those who really study this field will surely feel a sense of disobedience.

This kind of violation is probably like the relativistic mass equation has not been derived yet, and the atomic bombs have been created.

Although I don't care what other people think, since it is conditional to avoid this happening, it is worthwhile for him to take some time to do it.

After uploading the paper, Lu Zhou leaned back on the chair and regained his spirit and sat up from the chair.

"Xiaoai, are you ready?"

The drone floated over and a bunch of text popped up on the small TV.

【Ready! Master, where do we start? 】

Looking at the mechanical arm that had begun to dance up and down on the edge of the wall, Lu Zhou pondered for a while and said.

"Get a chair out first."

【……Eh? Lounge chair? 】

"Well, lying down and playing... It should be more comfortable, and the experience can't be sloppy. I went online to search the pictures of the personal engineering chair. Anyway, you are idle, and the materials are also here. I have to give You find something to do. Then there is the helmet... This part is well designed, the neural signal modem and the eeg sensor have to be integrated on it, let me think about it... well, just do it..."

Sitting at the computer desk and thinking about it, Lu Zhou, who is operating professional 3D design software, has gradually entered the working state.

At this moment, he did not know that the paper he had hanged on arxiv under the name of Dr. Z, both the author's name and the content of the paper itself, was completely ignited in the entire biological world.
