When Comrade Li Gaoliang was equipped with the value of titanium alloy through neural access technology and let him stand up again, the information technology experts of the Institute for Advanced Study once lamented this topic with him.

It's not just about getting a paraplegic with damaged spinal nerves back on their feet.

If complex visual and auditory signals can be compiled and simulated like action signals, so that the device can be directly connected to a neuroprosthesis or brain, perhaps the fantasy of neural access virtual reality technology that allows the mind to sneak into the digital world will no longer be a fantasy.

At that time, Lu Zhou said that this was indeed an interesting topic that could be studied, but there were a bunch of more important things waiting for him to do at that time, and this matter was left behind by him.

Now, coinciding with an innovative breakthrough in carbon-based chip technology, there is no place to spend the points on his body, and after being reminded by the person named Ye Nan, this matter was rethought by Lu Zhou.

Thinking of Vera, who was still lying in the sleep pod, Lu Zhou felt that if he couldn't wake her up for the time being, he would at least try to do something for her.

Although he also knew that the hope that this thing would work on her was quite slim......

After changing his clothes, Lu Zhou, who was sitting in front of the computer, combed through what he had written down.

To put it simply, the core components of the technology can be divided into three modules.

One is the collection of nerve signals, the other is the processing of nerve signals, and finally the simulation of nerve signals, that is, the stage where the information is finally fed back to the brain.

The technical difficulty of these three core components is increased sequentially.

The acquisition of neural signals is very simple, and there has been such a thing as an EEG sensor since the 80s, which is called an EEG sensor. And today, how advanced this technology is has even exceeded the imagination of ordinary people who do not have access to this technology.

Whether it's Silicon Valley's Eyemynd's VR system that allows users to navigate virtual worlds with their minds, or the sensation caused by 16 students at the University of Florida in 18 years who completed the world's first brainwave drone race, it's all a manifestation of this technology.

As for the second item, that is, the processing of nerve signals, the difficulty is more complicated than the acquisition of nerve signals.

Although on the surface it seems to be a test of a computer's ability to process information, in fact it is a rather complex programmatic problem.

The complexity lies in the fact that humans know very little about their own brains, except in limited circumstances, and the visual, auditory, and olfactory signals stimulate the brain far less strongly than the action signals.

I want to distinguish between these signals and compile a set of instructions for building the virtual reality world, as well as the operating system...... A series of such tasks can be classified under the second item.

As for the third item, the transmission of the electrical signals processed by the neural signal modem to the brain, that is, the most intuitive presentation of the user's experience, is the most complex and difficult part of the entire neural access virtual reality technology.

The reason is simple.

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

At present, the more cutting-edge practice is to implant a neuroprosthesis in the location of the cerebral cortex.

However, at present, this technology is mainly used to repair the functional impairment caused by nerve damage, and there is still a long way to go to simulate a series of signals such as vision, hearing, and smell.

At present, at the forefront of this field is the Institute of Nanoscience and Nanotechnology of Catalonia in Barcelona, Spain, through graphene materials, the researchers of the institute are designing a "neural interface" for the interaction between electrodes and brain tissues.

In fact, for the third core component, Lu Zhou does not have a lot of technical reserves.

The "answers" he received through the exchange of points were mainly focused on the second part, that is, the debugging demodulator of neural signals.

As for getting the brain to read the signal from the modem, he can only do the visual analogue step.

As for the sense of hearing and smell, and even the sense of touch and excitement, a series of sensations can only be achieved with the help of external stimuli.

For example, a headset built into a helmet or something.

Thinking of this, Lu Zhou still had some regrets.

If we can achieve a comprehensive simulation of all perceptions, we will probably be able to realize the final form of virtual reality technology.

That is, to connect the whole consciousness to the virtual Internet world, and get a second life in virtual reality.

At that time, whether you want to experience skydiving, rock climbing, or other things that you want to do in reality but have never done, or live a lifetime with paper people, you can do it.

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

It's just a pity that his subject level is not enough for the system to answer the second half of his questions, and if he forcibly redeems his points, he will be punished by at least two levels of scientific research efficiency.

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

It's just that it's more difficult.

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

In the spirit of a scholar who is not as happy as being happy alone, he finally selected a theoretical part that was not so advanced and did not involve patents from the materials he sorted out and compiled it into a paper.

He didn't expect this paper to ignite a revolution in virtual reality technology all at once. I just hope that this paper can play a role in inspiring other scholars engaged in this field to make more valuable results in this field.

As for the author of the paper......

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

Thinking that he had made a fuss last time and was almost recognized by his own people, this time he learned to be obedient and did not touch Arxiv, but opened the biologist's preprint website, BioRxiv.

pondered the process of uploading the manuscript for a while, but just as Lu Zhou was about to hang up the paper, he suddenly reacted with a thrill.

Wait, if this is thrown on BioRxiv, wouldn't it mean that you don't recruit yourself?

With a secret cry in his heart, Lu Zhou closed the BioRxiv website with black lines on his head, and re-hung the paper on Arxiv.

Although there are not as many biologists who pay attention to Arxiv as BioRxiv, from another point of view, more and more researchers in mathematics, computer science, and physics have joined the research of biology over the years, and the probability of encountering scholars who are engaged in both machine neural network and biological neural network research on Arxiv should be much higher than that on BioRxiv.

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

In fact, Lu Zhou is looking forward to meeting researchers who are good enough and like-minded with him to perfect the technology...... It's better to be able to solve all the troubles for him.

But, in fact, he didn't have much hope for this.

The biggest purpose of his release of this paper is to warm up the technology, and when he takes out the whole technology completely, it will not be too abrupt.

After all, if this thing is taken out directly, the jump is still a bit big, and ordinary people may not be able to see it, but people who really study this field will definitely feel a lot of disobedience from it.

This sense of dissonance is probably like the relativistic mass-energy equation has not yet been deduced, and the atomic bomb has already been built.

Although he didn't care what others thought, since he had the conditions to avoid this incident, it was still worth his time to do it.

After uploading the paper, Lu Zhou leaned back in the chair and stretched, and sat up from the chair again.

"Xiao Ai, are you ready?"

The drone whined and floated over, and a string of text popped up on the small TV.

【Ready!】 Host master, where do we start? (??????)?? 】

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

"Let's get a deck chair first."

【…… Huh? Deck chair? (?????) 】

"Well, lying down and playing...... It should be more comfortable to use, and the experience can't be sloppy. I went to the Internet to search for pictures of human engineering chairs, and you are idle anyway, and the materials are all here, so I have to find something for you to do. And then there's the helmet...... This part has to be well designed, and the neural modem and EEG sensor have to be integrated on it, let me think about it...... Well, that's it......"

Sitting at the computer desk while thinking, Lu Zhou, who was operating professional 3D design software, had gradually entered the state of work.

At this moment, he did not know that the paper he hung on Arxiv with the name of Dr. Z, whether it was the name of the author or the content of the paper itself, was completely popular in the entire biological community.
