"The CT scan of the brain shows that everything is normal and there are basically no problems."
Jian Jianyun looked at Zhang Li's inspection report and showed a satisfied smile.
"The prognosis of the surgery is also very good. As expected of a young man, he has strong recovery ability."
"Fortunately, Lao Chen was not asked to undergo surgery. His recovery will definitely not be as fast as yours. He is probably still dizzy now."
"For young people in their twenties, who are young and healthy, even if a stent is implanted in the cerebral blood vessels, the possibility of sequelae, such as the most common cerebral thrombosis, is very low, if not impossible. Young, but it’s hard to say for someone in their forties.”
She rambled on for a long time and then stopped.
Chen Yiqing listened silently, smiling, nodding from time to time, and agreed: "Doctor Jian is right."
As for other people, they will naturally not express any opinions.
When Jian Jian Yun finished speaking, he picked up the tea cup on the table and poured water.
Chen Yiqing spoke at the right time: "The first human test was very successful and brought us an unexpected surprise."
"It turns out that the brain's ability to learn and adapt is far more powerful than we imagined. I think Lily can handle some things that require more skills."
"So, I think I can go straight to the ultimate move."
"I understand, are you going to make a bionic manipulator next?" Wang Dali asked excitedly, looking like he was gearing up.
Chen Yiqing did not answer, but directly stretched out his right hand, clenched his five fingers into a fist, and slowly stretched them out. He did this several times before looking at Wang Dali and asked.
"How long do you think it will take to build a robot hand that can move its fingers freely and make some fine movements flexibly?"
"This..." Wang Dali suddenly got stuck. He silently stretched out his hand, picked up a pen, and rotated it a few times between his fingers. He felt the strength and balance in it and couldn't help but feel a little pain in his balls.
He said with some uncertainty: "Three months? Half a year? It depends on the specific needs and how precise it is. If you pick up a pen to write, it will probably take a long time. It will be much easier just to pick up a glass of water."
Chen Yiqing smiled slightly: "What if you are surfing the Internet? Using mobile phones and computers to type, play games, or even shop and order takeout?"
Wang Dali breathed a sigh of relief, thought for a moment, and frowned again: "It's a bit difficult, but it's not a big problem. Give me three months and I should be able to solve it."
Chen Yiqing smiled and shook his head: "Dali, your train of thought has gone astray. When it comes to computers, we should consider software solutions rather than pure hardware."
Wen Renlong listened, nodding his head and approving greatly.
"That's right, it's understandable that you hardware people can't change your mind for a while. If I were to do it, I wouldn't need any manipulator at all. I could just convert the brain signals into operations on the application. What about sending messages? Write emails, order takeout, so easy.”
Wang Dali glared at him: "Then you chop your hands off and let the program take care of everything for you? You don't have a single horoscope, do you really think of yourself as a digital being?"
Seeing that the two were about to quarrel, Chen Yiqing hurriedly said: "It's not that we don't want to make a robot. This is relatively difficult at the moment. We can only do a few simple movements for the time being. If we want to make more precise movements, it may take a little longer."
"That's why I thought that through some simple signal conversion, paralyzed patients can first restore their ability to communicate with the outside world."
"If they use a brain-computer interface, they can operate computers and mobile phones and surf the Internet proficiently. At least they will no longer feel lonely, can communicate better with family and friends, and will be full of hope in life."
"They can even learn to play games, shop, chat, read books, and have entertainment. In the information age, if a person can access the Internet, his life will become full and full."
"A fully functional bionic manipulator, as you said, would take less than a year and a half to complete."
"Our project must produce certain results so that patients can see hope before they can persist in the experiment. Otherwise, they will not be able to wait that long. Therefore, using thoughts to surf the Internet is a very good early-stage product that can meet certain needs of patients."
"When the need for Internet access is met, we will then build a robot to meet the patient's needs for complex daily behaviors."
"What do you think?"
Wang Dali's eyes suddenly lit up: "That's right, Chen Bo, you are absolutely right."
"If Zhu Jun could use a brain-computer interface to play games, he would be extremely happy."
"Our experiments can take months and a half, but patients don't have the patience. When they see no results for a long time, they will definitely become discouraged and don't want to come back."
"It's like a monkey experiment. You have to give them a little sweetness to keep cooperating."
"I understand, I understand, I understand so well."
He patted his thigh and instantly remembered the pastry that his boss had drawn for him. It was really big, round, fragrant and sweet. Apart from not being able to satisfy his hunger and only being able to smell it, there was really nothing wrong with it.
Once upon a time, he was like a monkey in the laboratory. As long as the boss gave him a few "pine nuts", he would be full of energy when working, as if he never knew what fatigue was.
However, one thing that humans are better than monkeys is that they have more desires and higher thresholds.
When the "pine nuts" couldn't satisfy him, he began to learn how to fish and mess around.
It wasn't until he came to Sanqing that the boss gave him enough bananas and they were delicious enough, which aroused his strong desire and worked happily.
Wang Dali came to his senses and asked the next question.
"Chen Bo, how will we implement it next?"
"Aren't we studying motor neurons? Aren't we studying each hand movement program? How can we let it directly control the computer?"
Chen Yiqing smiled: "Actually, the principle is still the same. We humans cannot operate computers as deeply as artificial intelligence, so we need to use the mouse, keyboard, and click on the screen to operate."
"The same goes for brain-computer interfaces. Instead of letting the brain directly control the computer, we let the brain imagine using its hands to control the computer through the keyboard and mouse. In this way, the relevant motor nerve signals can be converted into program instructions and communicated to the computer. ”
"The underlying logic of humans and computers is different. The brain is more advanced, the information processing is more three-dimensional, and the operation method is four-dimensional, because the human body's movements not only move in space, but also extend in time, and are a space-time integration.
"Computers can only process two-dimensional information. No matter how complex the image fragment is, it must be broken down into pixels for operation."
"The two sides are temporarily unable to communicate directly and can only control through indirect methods."
"Our research on the brain still has certain limitations. We are currently focusing on motor neurons, so we can only do this one step."
Wang Dali suddenly realized: "Wonderful, wonderful."
His thoughts began to diverge: "In that case, wouldn't it be possible to control the direction and movement of the wheelchair in the same way?"
Chen Yiqing nodded slightly: "Theoretically, it is indeed feasible. Let the patient imagine that he is operating the wheelchair forward and steering with both hands, and then convert it into electromechanical signals. After certain training, he can do it."
"Of course, this also depends on the person. Mutual learning and adaptation between the patient and the machine is also very important."
"Achieving the goal of maneuvering a wheelchair in a natural environment requires neuroplastic reorganization in the cerebral cortex."
"Some people's brains can quickly adapt to this change, while some people's brain activity patterns cannot adapt to this change, and the effect is not much better."
Having said this, he looked at Zhang Li next to him, with a hint of tenderness on his face.
"People like Lily have the best brain learning and adaptability, so they are very suitable as initial learning templates."
"With such an excellent program template, it will not be so difficult for newcomers to learn."
Wang Dali instantly understood why Chen Yiqing chose Zhang Li as the first tester.
He was greatly touched by this good intention and couldn't help but look at Zhang Li.
Her expression was very calm, her eyes contained expectation, and she did not show any irrational emotions at all.
Such a young scientist who is self-sacrificing, soft on the outside but strong on the inside, and emotionally stable is indeed the best experimental subject.
He understood the other party's behavior for a while. It might be just like his own college entrance examination. For a certain life goal, he must achieve it even if he sacrifices everything.
As for Wen Renlong on the side, his eyes were always on Zhang Li. There was admiration, pity, and tenderness in his eyes. The complex emotions were intertwined, and he was already fascinated by it.
****
What happens next, everything falls into place.
Zhang Li sat in front of the screen again.
This time, what appeared in front of her was a common computer interface, a keyboard and a mouse.
"It's much more difficult, but I believe you can do it, come on!"
Chen Yiqing and Wen Renlong cheered for her at the same time.
Zhang Li smiled lightly, made an OK gesture, then faced the computer and started operating it skillfully.
Kaka~
The mouse kept clicking, opening every icon on the desktop.
The browser is opened, the web page starts to scroll, after reading it, click the X and close it.
Then came the email window, with fingers flying, typing, and clicking send.
Finally, open Goudong's page, search for products, keep jumping, carefully select each product, enter the address, and click to place an order.
While Zhang Li was doing these things, her brain signals were continuously collected and transmitted to the laboratory computer for in-depth analysis, trying to extract a motor program model for operating the computer.
A week later, the data collection was completed and the algorithm optimization phase entered.
"How is it?" Chen Yiqing looked at Wen Renlong and asked with his eyes.
Wen Renlong nodded: "You can try it."
His hair was messy, his chin was covered with stubble of varying shades, and there was a faint smell coming from his clothes.
Chen Yiqing glanced at him gratefully and whispered: "It's done this time. I'll give you a long vacation and have a good rest for a few days."
Wen Renlong was typing on the keyboard intently without realizing it. It took him a while to react and casually responded: "Yeah."
"let's start!"
With a command, the brain-computer interface switch was turned on again.
The difference is that this time the connection is not to the robotic arm next door, but to the computer in front of you.
The keyboard and mouse were taken away.
Zhang Li drank the orange juice in the cup and put it back.
The hands hang down naturally, and the whole person lies relaxedly on the chair.
He began to concentrate on dealing with the computer in front of him.
She stared intently at the mouse arrow on the screen.
Soon, the arrows started to move, and I kept clicking on the icons on the desktop, popping up one window after another.
After a while, the WeChat chat window was opened.
The cursor flashes.
Zhang Li thought for a few seconds and then slowly typed a line of words.
"Hello, world."
At the other end of the room, Wen Renlong suddenly jumped up from his chair and said with a trembling voice.
"She, she sent me a message."
Looking at the words "hello world" in the dialog box, Wenrenlong's nose felt sour, and a line of hot tears flowed down uncontrollably.
He murmured to himself: "I understand, it turns out, it turns out, she has had this intention for a long time."
Chen Yiqing and Wang Dali couldn't help but look at each other in shock when they saw Wen Renlong's excitement.
Wang Dali whispered: "Aaron, what's wrong with you? Can't you just say hello? I see you are so excited that you shed tears. Are all of you algorithm makers so sentimental?"
Chen Yiqing asked with concern: "Are you too tired? The work here is almost completed. Do you want to take a rest?"
"You don't understand the meaning of this sentence to programmers. She said this to me, I understand, I understand, we are really connected."
Wen Renlong waved his hands while wiping his tears. The expression on his face changed. He was surprised and moved, moved and mixed with infinite joy, and even a trace of inexplicable shyness.
His heart was beating rapidly at the moment, and he was filled with fear and joy.
"Ah ah ah, what should I do? She actually said such a thing to me. How should I reply?"
A veteran in love for many years, at this moment, he was like a fledgling boy, at a loss, his mind went blank, he could only giggle.
The two people next to him looked at him more and more strangely. After exchanging glances again, they decided not to speak and just ignored him.
Chen Yiqing coughed lightly and said with joy on his face: "Very good, the function of connecting the mind to the Internet has been realized, and the project has been a great success."
"An extremely great and romantic technological miracle will be shown to the world in our hands."
"I think this is the true meaning of what Lily said to us."
"By the way, Aaron, since Lily said hello, you should also say hello to her."
This sentence brought Wen Renlong back from his endless reverie.
"good!"
He agreed immediately, then thought for a moment and typed a sentence happily.
while (i.findYou()){
if (()==you {
.print("Hello, World!");
}
}
Mouse click to send.
Watch this scene.
Chen Yiqing: "???"
Wang Dali: "???"
The two of them looked at each other with black lines on their heads, and at the same time showed expressions of "I'm afraid he's not a fool."
Chen Yiqing's forehead was throbbing with veins, but he took one look at the two huge bags under Wen Renlong's eyes and immediately swallowed back his words.
"What is Aaron trying to do now? Forget it, the project has been successful anyway, so don't worry about him."
Chen Yiqing comforted himself and turned around to walk away. He was afraid that if he continued to look at it, he would be tempted to take action and drive Wen Renlong out.
Wen Renlong, on the other hand, was completely unaware of everything around him. All his attention was focused on the dialog box in front of him.
He was uneasy and uneasy at the moment, enduring the torment and anxiously waiting for the other party's reply.
A few seconds seemed like an eternity to him.
Finally, the other party responded.
Zhang Li: "???"
Three big question marks appeared in the dialog box.
Wen Renlong felt as if he had been slapped in the head, staring blankly in front of the computer.
It took him a while to react, his brows furrowed, and he tried hard to think about the meaning.
"What's the meaning?"
"Could it be that my message was too profound and she didn't understand it?"
"Impossible, she is so smart, how could she not understand."
"It's not impossible. She has never learned programming."
"Then, how about changing to something simpler?"
"Forget it, it's a girl. She must be shy. Even if she understands, she pretends she doesn't understand."
He was scratching his head and scratching his head, restless, and his mood was like riding a roller coaster, floating to the clouds for a while, and falling into the mortal world for a while.
At this time when my thoughts are flying and turning over and over again.
Suddenly, there were two beeps.
Zhang Li sent another message, this time it was simple, just a smiley face.
However, Wen Renlong instantly beamed with joy as if he had seen the most beautiful words in the world.
All the gloom in my heart disappeared in an instant, just like the sky cleared after the rain.
All that was left was a wild laugh.
"Hahaha, I knew it, she must have understood it."
