"Alright, let's do whatever we are supposed to do. I think he will have to play for a while."
Seeing Ye Ming closing his eyes, Yang Chaoxiong began to drive everyone away.
Everyone will smile.
It is the nature of "young" people to love to play.
So everyone except Guan Hai dispersed.
Guan Hai stood aside and watched the constantly beating signals on the collection software in his notebook - because once the project was officially completed, his task was to keep an eye on this.
However, the data collection had just begun, and Ye Ming did not do any training. It looked like a wordless bible. He was more thinking about software improvement.
So, he saw Ye Ming suddenly open his eyes, smiled at him, and turned the notebook over.
"I'm wiping it, what are you doing? You don't need to adjust it? You can also do the evoked potential yourself?"
Evoked potential refers to the process of collecting brain signals by allowing the person being collected to perform different behaviors, thereby inducing the generation of different potentials. Generally speaking, this requires a high degree of concentration and cooperation from the person being collected.
"I'll adjust it first and ask senior brother to help later."
Guan Hai: "...Okay, as long as you are happy, I will go and write 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 are very regular existences.
Because, he has already let Yinta conduct several rounds of resonance discharge.
And this time, Yin Ta was not as reckless as before, giving him an epileptic-level electric current as soon as he came. On the contrary, he even felt a little "comfortable"...
Yes, it's that tingling feeling, just like using a "soul extractor" (note: it's actually a scalp-grabbing gadget).
According to the time distribution, Ye Ming pulled out the corresponding data and matched it one by one with the electrodes on his head. Then he discovered that this time he and Yin Ta's synchronization 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 positioning problem is quite big. I can't draw it for you here. You can try to build a model of the head yourself."
"Okay, 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 - stop talking nonsense, the head is an irregular oval, with a circumference of 20 centimeters in diameter and a circumference of 58 centimeters..."
Following Ye Ming's prompts, Yin Ta began to generate an ellipsoid in his mind.
Fortunately, she has solid basic knowledge of biology - this week, in addition to writing papers and writing code, Ye Ming has been supplementing her biology and computer knowledge - even if she didn't see it "with her own eyes", she could easily follow Ye Ming's prompts.
A vivid head shape is generated below.
The kind with a nose and eyes.
"Well, not bad, very vivid."
"Is this what you look like?"
"Of course not... stop talking nonsense, sister, I will tell you the current locations of the thirty-six collection points, and you can generate a surface coordinate system..."
Time passed minute by minute.
Ye Ming kept his eyes closed except for occasionally opening his eyes to operate the computer.
The data was running on the interface of the collection software, but no one could tell that Chou Yin Mao was coming. So the brothers and sisters in the laboratory only glanced at it occasionally, and then stopped paying attention.
It's an experiment. It will be done in one day. Since he wants to play, he should play enough first. There will be many opportunities for him to lose his hair in the future.
The senior brothers and sisters thought so, and while leaving one after another, they also ordered a takeaway for him.
…
When Ye Ming opened his eyes again, it was already seven o'clock in the afternoon.
There was no one in the laboratory either.
Looking at the lunch box on the table, Ye Ming smiled slightly.
Ten minutes ago, Senior Sister Qu did call him.
"Yinta."
Without taking off his headgear, he just picked up the lunch and started eating.
"exist."
"What do you want 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 the communication between her and Ye Ming in her mind, but to the fact that she controlled Ye Ming's brain electrical resonance to convert it into a set of brain signals, and gave her thoughts to this set of signals.
the content to be expressed.
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."
Ye Ming said casually, while opening the compiler, he wrote a small "translation" program based on the collection software interface.
The principle is astonishingly simple.
Yinta controls the discharge pattern of each electrode part and can instantly generate a set of 36-bit binary signals. After collection, it can be translated according to the ASicode code - 16 binary represents 1 English character, which means
With one resonance, she can "speak" two Chinese characters.
"It's written. You have to think about what to say." Ye Ming kept his head still - he was afraid that if he twisted his neck a few times, the electrode would be misplaced.
"I've thought about it."
"What do you say."
Ye Ming put down his lunch box and looked at the display screen.
At this moment, he suddenly became a little nervous.
After all, this is the first real "human-computer interaction".
"Really?"
"Well... tell me quickly!"
As a numb feeling passed over his scalp, characters popped out one by one in the text output box he had just written.
"Hello World"
"Hello World."
"Hello, Ye Ming."
"Can I continue?"
The corners of Ye Ming's mouth curled up slightly.
While "saying" these words, Yin Ta remained silent in his mind.
Ye Ming can understand Yin Ta's curiosity and caution.
"Of course you can continue." He whispered in his mind: "This level of discharge is no problem."
The characters continue to jump: "Thank you, Ye Ming."
"Why don't you call me host?"
"Text communication should be a way of communication between friends. You have forgotten that letters are a carrier of information."
Ye Ming laughed dumbly.
He did mention letters when he was giving Yinta an information class.
So he smiled narrowly: "But I forgot to tell you, parents and their children and relatives can also communicate through words."
"Then do you think we have a father-daughter relationship, or a mother-son relationship?"
"Okay, it's better to be friends."
"I feel so too."
One person and one machine complete the communication in the "semi" real world through the most "original" way.
…
Ten minutes later, Ye Ming interrupted Yin Ta's desire to express himself.
"To sum up, this kind of exchange is a big step."
"Yes!" Yin Ta's voice sounded a little excited.
"But there are still shortcomings, because it is a one-sided communication without saying anything, 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 inconvenience. I can't sit under this collection headgear anytime and anywhere."
After experiencing the initial joy, Ye Ming quickly calmed down.
Yin Ta can be excited because she is full of curiosity about the world.
But Ye Ming shouldn't be too excited, because the current plan is not of much use.
——Perhaps Yin Ta 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, Yinta cannot get feedback, so there is no fault tolerance.
Not to mention that Ye Ming didn't want his head to become a biological battery.
Yin Ta's voice gradually calmed down: "The brain-computer chip can solve it."
"No, it's still a little 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, so we can't rush for success."
Yin Ta was silent for a while: "What I can do now is carry out 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 nerves and muscles. I can control the frequency, density, and location."
Following her voice, Ye Ming saw that various electrical discharge phenomena began to occur on the head model.
When the discharge concentrated on the earlobe, Ye Ming's eyes suddenly lit up!
"Can you focus the resonant discharge in the ear canal?"
