Chapter 1064

When Li Gaoliang was given the value of titanium alloy through neural access technology to stand up again, the information technology experts of the Institute of higher learning once lamented this topic with him.

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

If we can simulate the complex visual and auditory signals, just like the action signals after being compiled, and let the device directly connect with the neural prosthesis or brain, we can't say that the neural access virtual reality technology that makes the consciousness dive into the digital world in fantasy is no longer a fantasy.

At that time, Lu Zhou said that it was really an interesting topic to study, but at that time, there was still a lot of more important things waiting for him to do, which he left behind.

Now, just in time for the innovative breakthrough of carbon based chip technology, there is no place to spend more points on it. After being reminded by the person named Ye Nan, it was recalled by Lu Zhou.

Thinking of Vera, who is still lying in the sleeping cabin, Lu Zhou feels that if she can't wake her up for the time being, at least try to do something for her.

Although he also knows that the hope that this thing can work on her is quite slim

After changing clothes, I sat in the land boat in front of the computer and combed the things I wrote down.

Simply speaking, the core component 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 the last is the simulation of neural signals, that is, the last stage of feedback information to the brain.

The technical difficulty of these three core components increases in sequence.

The collection of neural signals is very simple. As early as the 1980s, there was the EEG sensor, the so-called EEG sensor. Today, how advanced this technology is, even more than the imagination of ordinary people who can't touch it.

Whether it's the VR system created by eyemynd in Silicon Valley that users can navigate the virtual world through their thoughts, or the sensation caused by the world's first brain wave UAV competition completed by 16 students from the University of Florida in 18 years, it's a manifestation of this technology.

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

On the face of it, it only tests the computer's ability to process information, but in fact, it is a rather complex procedural problem.

This complexity lies in the fact that human beings know little about their own brain, except for the limited situation, the visual signal, auditory signal and olfactory signal can not stimulate the brain as much as the action signal.

I want to distinguish these signals, and compile a set of instructions used to construct the virtual reality world, as well as the operating system Such a series of work can be classified into the second item.

As for the third item, it is the most complex and difficult part of the whole neural access virtual reality technology to transmit the electrical signal processed by the neural signal modem to the brain, which is the most intuitive presentation link of the user's experience.

The reason is simple.

Just like the difficulty people encounter in developing the second core component of the technology, if we can't even understand the brain machine, how can we output signals to the brain machine that can be read by it?

At present, the more advanced approach is to implant a neural prosthesis in the position of the cerebral cortex.

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

At present, in this field, the Research Institute of nanoscience and nanotechnology in Catalonia, Barcelona, Spain, is ahead of the comparison. Based on graphene materials, the researchers of the Institute are designing a "neural interface" for the interface between electrodes and brain tissue. As for the specific research steps, only they know.

As a matter of fact, for the third core component, there is not a lot of technical reserve for the ship.

The "answer" he got through integration mainly focuses on the second part, which is the debugging demodulator of neural signal.

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

As for the sense of hearing and smell, even the sense of touch and excitement, a series of feelings can only be realized by external stimulation.

For example, put a headset in the helmet.

Think of here, land boat still has some regrets.

If we can simulate all aspects of perception, we can probably achieve the final form of virtual reality technology.

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

At that time, whether you want to experience skydiving, rock climbing, things you want to do in reality but haven't done, or spend your whole life with a paper man, you can do it.As for other uses, you can think about them slowly.

Unfortunately, his subject level is not enough for the system to answer the second half of his questions. If he forcibly exchanges credits, he will be punished by at least two levels of scientific research efficiency.

The only thing that makes him happy is that at least the system has marked out the cost of points, which shows that the problem is still solved in his lifetime.

It's just that it's more difficult.

Thinking of this, I sat in front of the computer and thought for a while.

In the spirit of scholars that dullele is not as good as the others, he finally selected a less advanced theoretical part which does not involve patent from the collected materials and compiled a paper.

He didn't expect this paper to ignite the revolution of virtual reality technology at once. He just hoped that this paper could play a role in attracting more valuable achievements from other scholars in this field.

As for the author of the paper

Considering that the core content is mainly in the fields of computer and biology, Dr. Z's vest was put on again.

He thought that he had a black dragon last time and was almost recognized by his own people. This time, he learned well and didn't touch arXiv. Instead, he opened biorxiv, a preprint website dedicated to biologists.

After pondering over the process of uploading the manuscript for a while, Lu zhougang was just about to hang the paper when he suddenly got a sharp response.

Wait a minute. If it's thrown on the biorxiv, isn't it just a no brainer?

In his heart, he said that he was so dangerous that Lu Zhou shut down the website of biorxiv and hung his paper on arXiv again.

Although there are not as many biologists who pay attention to arXiv as those on biorxiv, from another perspective, in recent years, more and more researchers in mathematics, computer and physics have joined in the research of biology. The probability of encountering scholars who are engaged in the research of both machine neural network and biological neural network on arXiv is much higher than that on biorxiv.

Of course, biological neural network and mechanical neural network are among the most difficult parts in biology and computer science. It's no exaggeration to say that few scholars can master both fields at the same time.

In fact, although Lu Zhou is looking forward to meeting enough excellent researchers who share the same interests with him to improve the technology It's better to get rid of all the trouble for him.

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

The biggest purpose of his paper is to preheat the technology. When he takes out the whole technology completely, it will not seem too abrupt.

After all, if this thing is taken out directly, it's still a little jumping. Ordinary people may not see it, but people who really study this field must feel a lot of disobedience.

It's like the relativistic mass energy equation hasn't been derived yet, and the atomic bomb has been built.

Although he doesn't care what other people think, it's worth taking a little time to avoid it.

After uploading the paper, Lu Zhou leaned on the chair and stretched himself out, then he got up from the chair again.

"Ai, are you ready?"

The drone came whistling and a string of words popped up on the small TV.

[ready! Master, where shall we start? "(.

"Let's get a recliner out first."

【…… Hey? deck chair? (???)]

"well, lie down and play It should be more comfortable to use. You can't be careless in the experience. I'm going to search for a picture of an ergonomic chair on the Internet. Anyway, you are also idle. There are all kinds of materials here. I have to find something for you. And then the helmet This part needs to be well designed. The neural signal modem and the EEG sensor must be integrated on it. Let me think Well, that's it... "

Sitting in front of the computer desk, thinking and operating the professional 3D design software, the ship has gradually entered the working state.

At this moment, he didn't know that the paper he hung on arXiv in the name of Dr. Z, whether it was the author's name or the content of the paper itself, was completely hot in the whole biology field.
