From black technology to super engineering

"Okay, what should everyone do, I guess he will be playing for a while."

Seeing Ye Ming close his eyes, Yang Chaoxiong began to drive away the crowd.

Everyone smiled knowingly.

"Young" people, it is their nature to love to play.

So except for Guan Hai, everyone else dispersed.

Guan Hai, on the other hand, watched the constantly beating signal on the acquisition software in his notebook—because once the subject was formalized, his task was to keep an eye on it.

It's just that the data collection has just started, and Ye Ming hasn't done any training. It looks like a book without words. He is thinking more about software improvement.

So, he saw Ye Ming suddenly opened his eyes, smiled at him, and turned the notebook over.

"Damn it, what are you doing? You don't need to debug it? You also make the evoked potential yourself?"

Evoked potential refers to the process of brain signal collection, allowing the subject to perform different behaviors, thereby inducing different potentials. Generally speaking, this requires the subject to be highly concentrated and highly cooperative.

"I'll adjust it first, and I'll ask my brother to help me later."

Guan Hai: "...Okay, as long as you're happy, I'll go and brush up some papers."

...

Ye Ming opened the historical data of the previous minute.

In Guan Hai's eyes, these signals are wordless scriptures, but in Ye Ming's eyes, they exist very regularly.

Because, he had made Ita undergo several rounds of resonant discharges.

And this time, Ita was not as reckless as before, giving him an epileptic-level high current as soon as he came, on the contrary, he was even a little "comfortable"...

Yes, it's that crispy, numb feeling, just like using a "soul extractor" (note: it's actually a small gadget for scratching the scalp).

According to the time distribution, Ye Ming dragged out the corresponding data, and then corresponded with the electrodes on his head one by one, and then he discovered that this time he synchronized with Ita, but actually only collected less than 10 electrode signals.

Looking at the data, he was silent for a few seconds and then quickly closed his eyes.

"It seems that the problem of positioning is quite big. I can't draw it for you here. You can try to build a model of the head yourself."

"Well, it's a sphere, right?"

Ye Ming: "...it is not allowed to say that the head is like a ball."

"Why?"

"Because it's a curse word—don't talk nonsense, the head is an irregular ellipse, with a diameter of 20 centimeters and a circumference of 58..."

Following Ye Ming's prompt, Ita began to generate an ellipsoid in his mind.

Fortunately, her basic knowledge of biology is solid—this week, Ye Ming was just supplementing with knowledge of biology and computers in addition to writing papers and writing codes—even if she didn’t see it “with her own eyes”, she easily followed Ye Ming’s prompt. Next, a vivid head shape was generated.

The one with the nose and the eyes.

"Well, not bad, very vivid."

"Is this what you look like?"

"Of course not...don't talk nonsense big sister, I'll tell you the current location of the thirty-six collection points, you generate a surface coordinate system..."

Time passed minute by minute.

Ye Ming kept his eyes closed except for occasionally opening and operating the computer.

The data on the interface of the collection software is running, but no one can see that he is ugly. So the brothers and sisters in the laboratory just glanced at it occasionally, and then stopped paying attention.

As for the experiment, it will be finished in one day. Since he wants to play, he should play enough first. There will be plenty of opportunities for him to lose his hair in the future.

Thinking so, the brothers and sisters left and ordered a takeaway for him by the way.

...

When Ye Ming opened his eyes again, it was already seven o'clock in the afternoon.

The lab was also empty.

Looking at the lunch box on the table, Ye Ming smiled slightly.

Ten minutes ago, Senior Sister Qu did call him.

"Ita."

Without taking off the headgear, he picked up the boxed lunch and started eating.

"exist."

"What are you going to say later?"

"I'm thinking."

It can be heard that the voice in my head is a little nervous.

——Ye Ming asked her what she wanted to say, not referring to her communicating with Ye Ming in her mind, but referring to her converting Ye Ming's brain electrical resonance into a set of brain signals, and giving her thoughts on this set of signals. what to express.

This is the first time she expresses her will to the world.

That's why Ye Ming asked her.

"Then think about it slowly, you will convert the signal directly into binary later, and I will write a small program."

While talking casually, Ye Ming turned on the compiler and wrote a small "translation" program based on the acquisition software interface.

The principle is shockingly simple.

That is, ita controls the discharge law of each electrode part, and can instantly generate a set of 36-bit binary signals. After collection, it can be translated according to the corresponding ASCII code and Unicode code——16 binary signals represent 1 Chinese character , which means that she can "speak" two Chinese characters with one resonance.

"It's finished, do you think about what to say?" Ye Ming kept his head still - he was afraid that the electrodes would be misplaced if he twisted his neck a few times.

"Thought it out."

"What do you say."

Ye Ming put down his lunch box and looked at the display screen.

At this moment, he also suddenly became a little nervous.

After all, this is the first real "human-computer interaction".

"Really?"

"Well... hurry up!"

As a tingling sensation passed over his scalp, characters jumped out one by one in the output box of the text he wrote just now.

"Hello World"

"Hello World."

"Hello, Ye Ming."

"Can I continue talking?"

The corners of Ye Ming's mouth curled up slightly.

While "saying" these words, Ita kept silent in her head.

Ye Ming could understand Ita's curiosity and caution.

"Of course you can continue." He whispered in his mind: "This level of discharge is no problem."

The characters continued to beat: "Thank you, Ye Ming."

"Why is it not called the host anymore?"

"Text communication should be the way of communication between friends. You have forgotten that letters are the carrier of information transmission."

Ye Ming laughed dumbfounded.

He did mention letters when he gave Ita an information class.

So he smiled narrowly: "But I forgot to tell you that parents, children and relatives can also use text to communicate."

"Then what do you think, are we a father-daughter relationship, or a mother-son relationship?"

"Well, it's better to be friends."

"I feel so too."

One person, one machine, through the most "primitive" way, completed the communication in the "semi" real world.

...

Ten minutes later, Ye Ming interrupted Ita's desire to express.

"To sum up, such communication is a big step."

"Yes!" Ita sounded excited.

"But there are still shortcomings, because it is a one-sided communication and it is not efficient."

"That's right!"

"So, the next upgrade plan can be to add more electrodes—but there is another bigger problem, which is inconvenient. I can't sit under this collection headgear anytime, anywhere."

After experiencing the initial joy, Ye Ming quickly calmed down.

Ita can be excited because she is full of curiosity about the world.

But Ye Ming can't be too excited, because the current plan is not very useful.

——Maybe Ita can use this method to complete some data/information input work for him, such as writing a code for him.

But since this is only a "unilateral" output, Ita cannot get feedback, so there is no fault tolerance.

Not to mention that Ye Ming doesn't want his head to become a biological battery.

Ita's voice gradually calmed down: "The brain-computer chip can solve it."

"No, it's still too early to talk about brain-computer chips. Even if I can promote the technology, it won't work." Ye Ming's eyes flashed, and then he said softly: "That should be a task for a long time in the future, and we can't rush for success."

Ita was silent for a while: "What I can do now is to perform wave-related resonance, which can be controlled to a very precise level."

She once again generated a head model in Ye Ming's mind.

"Your bioelectricity exists in the nerves and muscles, and I can control the frequency, density, and location."

Following her voice, Ye Ming saw that various discharge phenomena began to be generated on the head model.

When the discharge concentrated on the earlobe, Ye Ming's eyes suddenly lit up!

"Can you focus a resonant discharge in the ear canal?"

"sure."

Ye Ming took a deep breath.

"I think I probably have an idea."

"This place is too small to write."

Ye Ming smiled and said the classic side note.
