I, the delivery boy, will be invincible after signing in for three years

It's just that this comfortable life was broken by a phone call from Ren Xiaochuan after only two or three days.

Mr. Ren, what happened to you calling me over in such a hurry?

Professor Chen, good news or bad news, which one do you want to hear first?

Ren Xiaochuan took a folder and sat opposite Chen Nuo.

Let me talk about the bad ones first, let me see how bad it can be?

Chen Nuo made himself a cup of tea, no matter how bad it was, it was better than the previous one.

Let me say yes first!

Mr. Ren sighed: The good news is that the six-sense data of 2000 people in the first phase have all been collected, and we have established a preliminary six-sense resource library through distributed arrangement.

我们对这2000人的六感做了统计和分析，有87.25%的试验者的六感数据波动在2%以内，有8.26%的人波动在2-5%，有4.16%的波动在5-10%，0.33%的人波动在10以上，最夸张的一个波动到了25%。

Ren Xiaochuan handed over the document in his hand, and Chen Nuo looked through the data carefully with a serious expression on his face.

A fluctuation of 2% has almost no big deviation, but a deviation of more than 5% will make things worse.

For example, the international definition of pain is level 12. In the future, in the virtual world, you can choose to adjust it yourself. It was originally level 25 pain, but when there was a 8% deviation, it became nearly level [-] pain. This is easy to cause accidents. of.

Found a problem?

Have!

Ren Xiaochuan answered very quickly, but the answering voice was a bit weird, with a wry smile.

The problem is with the group of people you're looking for.

People with normal numerical fluctuations are office workers, while those with large fluctuations are people who travel outside all the year round, with extremely strong psychological quality, and the fluctuations in external stimuli are much gentler than normal people.

For the group of Secret Service people, this is more obvious. When you prick him with a needle, his brain fluctuations are almost flat, there is no fluctuation, as if he has no pain!

After listening to Mr. Ren's analysis, Chen Nuo couldn't laugh or cry. How could he think that there was such a problem in it.

Therefore, we need a large base of ordinary people to collect data for accurate summary analysis, but once a large number of ordinary people are found, the news will inevitably leak, so it is up to you to make up your mind.

Chen Nuo stared at the report for a while: Mr. Ren, if we recruit volunteers, how soon can you get results?

If it's only a few months, it's easy to keep secret. If it's too long, then we can only find another way.

Ren Xiaochuan's face turned serious.

This is related to the bad news I will say next. If the bad news cannot be resolved, the advancement of the virtual reality project will be far away.

Chapter 433 The Dilemma of Virtual Reality

you come with me!

Ren Xiaochuan stood up and walked outside, Chen Nuo also followed.

In a spacious laboratory, there are dozens of helmets, large and small, each of which has a different shape, and it is full of technological sense from the outside.

Professor Chen, you have to experience it first, and then we will talk about the problem!

Under the guidance of the staff, Chen Nuo lay down on a strangely shaped white sofa chair, and then put on a device that was the same as a battery car helmet, except that several wires were connected to the back.

Professor Chen, we are ready to start, please calm down and don't resist!

Just as Chen Nuo lay down, the staff next to him said something and turned on the device.

Chen Nuo felt a faint negligible pain, and then there was nothing else.

On the computer screen on one side, two sets of brainwaves were jumping back and forth, but they just didn't match up.

Chen Nuo lay on the sofa and hadn't entered the virtual reality for a long time. When Chen Nuo was in a daze, he suddenly found himself in a garden of about [-] square meters.

Professor Chen, welcome to the virtual reality testing space!

The voice sounded in the garden, and Chen Nuo looked at the garden curiously. The flowers in the garden were in full bloom, very delicate and beautiful.

He bent down and touched the blooming lily, clearly feeling the softness of the petals and the faint fragrance of the flower. When he squeezed hard, he could even feel the water oozing from the petals.

Just as he was observing carefully, a majestic roar suddenly came from outside the garden. Before he could react, he saw a three-meter-long tiger appearing and pounced on him with its bloody mouth wide open.

Chen Nuo was startled suddenly, his body stepped back suddenly, and his hands drew an arc to stick to the tiger.

The next moment the tiger was thrown out. After the tiger landed on the ground, its two brass bells stared at Chen Nuo, and disappeared after a few seconds.

After Chen Nuo let out a long breath, the ground suddenly trembled.

I am!

He came in a hurry, the ground cracked, and Chen Nuo fell down.

When he opened his eyes again, he returned to reality.

This?

Taking off the helmet with the help of the staff, Chen Nuo leaned on the sofa and frowned.

He seemed to have discovered the bad news that Academician Ren Xiaochuan said.

Professor Chen, it seems that something has been discovered!

Ren Xiaochuan smiled at Chen Nuo's appearance, and Chen Nuo nodded.

Mr. Ren, there are two points in the question, please see if I am right!

First point, the time to enter the virtual space is too long, if my guess is correct, I just used it for about 15-20 minutes.

Second, the virtual space is unstable. When suddenly frightened or for other reasons, it will flash back, and when the mood swings are relatively large, the things formed in the virtual reality will be illusory.

Snapped!Snapped

Mr. Ren applauded, his eyes filled with amazement, and the other professors also showed expressions of admiration.

Chen Nuo is so frankly a monster, just by experiencing it, he discovered the problem.

Professor Chen, to enter the virtual space, the user’s brainwaves must be consistent with the brainwaves collected for the first time. on, it's hard to get in.

We use the method of cerebral cortex microcurrent, which sends a group of hypnotic brain waves to the brain to calm down the user, but this method varies from person to person, and it enters very quickly. Among the people we tested The slowest took more than two hours.

When Ren Xiaochuan said this, the mouth corners of the professors next to him twitched. In that experiment, the tester did not enter the virtual space, but almost fell asleep the person in charge of measuring the data.

Difficult to enter in an instant, this kind of experience is terrible. For example, when you meet to play a game, but one person enters the game and dies more than ten times, the teammate only enters, that is really terrible.

For another example, if you use this office and clock in at eight o'clock, but you can't enter the void world for a long time, you must be late every day.

Professor Chen, the second flashback problem is mainly caused by two problems. One is a hardware problem. The chip placed in the helmet is not working, but this can be solved as long as the chip technology breaks through or two more chips are installed.

The main root cause is that when people enter virtual reality, they are in a latent sleep state. The International Health Organization divides sleep quality into five types from high to low, which are sweet, comfortable, bitter, restless, and sleepless. In a state of restlessness.

At least 2000% of the 92 people we tested were below bitterness, only a few reached comfort, and as for sweetness, none.

When Ren Xiaochuan said this, Chen Nuo immediately understood the problem.

If you are in a light sleep state, your brain is actually still working, and the amount of information processed is much more than when you are awake. At this time, you are dreaming.

This is why some people sleep for 10 hours, but still can't wake up and sleep well!

The reason for this is that we receive too much information from the outside world, such as playing with mobile phones and watching TV before going to bed, as well as work pressure and so on.

In the latent sleep state, people are easy to wake up, and of course they will flash back when they enter the virtual world and are frightened.

Thinking of this, Chen Nuo's face became a little ugly. Could it be that when launching virtual reality, it is necessary to improve the sleep quality of the user first, so that the user can achieve the sweetest and best sleep state?

Isn't this bullshit?It is much more difficult than the four major projects.

Of the 76 billion people in the world, more than half have sleep problems.

If there was a way to solve this problem, he would have the Nobel Prize in Physiology or Medicine, worth trillions of dollars every year.

Mr. Ren, how did you get the hypnotic brain waves?Did you let the user wear a helmet to sleep, and then get it through data monitoring?

Yes, we used this most primitive method!

Chen Nuo nodded, no wonder there was such a result.

Scientists can judge the user's sleep level through the tester's muscle activity, breathing rate, eye movement, and brain activity. Different sleep stages have different characteristics and functions, and then capture brain waves for analysis.

This kind of problem is that the quality of sleep of the testers is in the bitter stage, and the brain waves obtained can only hypnotize the user to the bitter stage.

If the user's spirit is in a state of excitement, then it's over, and it depends on who consumes the most, the user and the helmet.

Professor Chen, let's talk about the first entry problem. We have thought of several ways to shorten the time to enter virtual reality.

The first is to use the virtual reality ecological cabin to adjust the temperature, humidity and other factors that affect sleep in the ecological cabin, so that the ecological cabin can achieve the best sleeping environment.

When Ren Xiaochuan said this, he pointed to a device in the corner that looked like a freezer.

After Chen Nuo stepped forward and looked around, his eyes were full of weirdness, no matter how he looked at it, he seemed to be lying in a crystal coffin.

Cover it with a white cloth and sound the suona, and send it directly to the crematorium.

This is the most ideal at present, the testers can basically fall asleep within a few minutes, and 45.22% of the testers have entered a comfortable sleep state.

But this kind of cost is too high. Just such a set needs 50 RMB, and it is estimated to be around 40 RMB for mass production. How many of these are affordable?

Chapter 434 Lucid Dreaming

10 yuan!

The standard helmet cannot exceed 10 yuan, which is Chen Nuo's bottom line for the price of virtual reality helmets.

Although the ecological warehouse looks a bit like that, it is not impossible to consider it. It is possible to make some for those local tyrants.

The price is a bit more expensive, but it is better than safety.

Because after wearing the helmet, entering virtual reality after entering deep sleep, the perception of the outside world is reduced to the lowest point.

If someone has malicious intentions, it is an accident.

But if this kind of ecological warehouse is made of special materials, it can last for several hours even in the event of a fire or an earthquake.

Chen Nuo talked about this consideration with Ren Xiaochuan, asked the people in the laboratory to make a note, and then investigated the market later.

The second method is to use the principles of ergonomics to design a recliner. The sleeping posture and sleep quality are related, but it is not universal. Everyone is an individual and has different habits.

Chen Nuo got up and looked at the reclining chair under him. No wonder the shape of the chair was a bit strange, but it was very comfortable to lie on.

In the next ten minutes, Ren Xiaochuan explained more than a dozen methods piecemeal.

For example, adding lullabies, psychological hints, sleeping pills, etc. Chen Nuo shook his head when he heard it.

Professor Chen, in fact, the simplest method is also the most stupid method, which is to find testers whose sleep quality has reached a sweet state. According to our estimation, there are about one or two hundred data, and we can get a basis If you do more tests later, you will always get hypnotic brainwaves!

The method is as simple as it is simple, and as difficult as it is difficult.

Among the 2000 testers in the first phase, none of them were in a sweet state.

Even if it is one in two thousand, if 200 people are found, then 40 people will have to be tested. Based on 800 tests a day, it will take [-] days, which is converted into two and a half years.

This is still the best ideal state, and the actual time should be at least doubled, not to mention the financial, material and human resources used.

Besides, will the sweet state definitely solve the problem of crashing?

Chen Nuo stared at the helmet and let out a low cry in his heart.

System, sign in!

Ding!The sign-in is successful, congratulations to the host for getting a piece of garbage.

Hey!

Chen Nuo cursed secretly in his heart, as expected, he couldn't rely on the system at this juncture.

He had discovered a long time ago that the system would only provide assistance once on a project, either at the beginning or at the end, and he had to do the rest by himself.

That's fine, you can't just look for the system as soon as something goes wrong, what if the system is gone someday?

After cursing inwardly, Chen Nuo thought about whether to spend the [-] reputation points and draw a lottery for all of them.

One thousand times of gold consecutive draws, if the human mind experience card is drawn, there is probably room for solving this problem.

Do you want to do it?

Chen Nuo was in a daze.

Professor Chen!

Professor Chen?
