Blind people who have been trained can use their hearing to interpret echo information, judge the distance between an object and themselves, the size and even density of the object itself, etc., thereby forming a rough image of the object in the brain to assist them in walking, sitting and lying.

However, the training itself is quite difficult, requires effort and time, and sometimes has high requirements on the financial ability of the participants. Even if these conditions can be met, there are very few blind people who can actually do it.<

/p>

The fundamental problem lies in the human brain. Although the human brain is very powerful and has huge and complex computing power, few or even no one can fully utilize the brain's capabilities. People cannot explain clearly the sounds and images that appear in the brain.

How it was formed? I just naturally recalled a melody and a picture.

This "instinct"-like processing method is not the same as the algorithm of an intelligent computer that "knows the whole picture, so it runs". It is full of randomness and cannot be reproduced perfectly. It cannot summarize causal relationships and lessons learned, and it cannot be sorted out.

Systematic knowledge and methods are left for future generations to learn and imitate.

Therefore, it is difficult for blind people who have mastered brain imaging skills to pass on their experience, and it is even more difficult for sighted researchers to understand what it is like to rely on feedback information from other senses for visual processing.

Insufficient samples, slow research progress, no obvious breakthroughs in results, and low willingness of employers to produce related instruments... For various reasons, the most common assistive tools/creatures for the blind on the market are still blind canes and guide dogs, and their significance is "

"Guidance" and "obstacle avoidance" are the main ones, and little help is provided for "whether you can see or not".

This is a kind of second best, a helpless compromise.

But now, the situation has taken a turn for the better.

Qin Yuqiao, who has echolocation and brain imaging capabilities, is not blind in the objective sense.

She herself can become the control group, collect data, summarize experience, and even... sort out a more streamlined and convenient algorithm.

This is the reason why Qin Jue's mind is shaken.

In the apocalypse, the little fox's mental power is as vast as the sea. He can distinguish obstacles and walk freely just by relying on the sound and color formed by synesthesia. Other people who have lost their vision due to various reasons do not need others to teach them. They must first do it themselves.

Under the pressure of survival and combat, I automatically mastered the ability to rely on other senses.

In that environment, when everyone sees a disabled person, the first reaction is not "Okay! I caught a weakling", but a strong fear, because if you think about it with your toes, you will know that a physically weak person can still be well.

Those who have survived to this day must have horrors that are incomparable to ordinary people.

But now is not the end of the world, it is a time of peace.

There are many people in society who are born unlucky or encounter disasters the day after tomorrow, just like Qin and Qing in "The Crucible". They are flawed and weak, but this does not mean that they do not have the right to live a good life.

Qin Yuqiao's face was soaked with tears.

What Qin Jue thought of, she also thought of. Surprise and joy filled his chest and lungs in an instant. Qin Yuqiao's throat was tight and he was choked with sobs, unable to say anything.

Suddenly, she took the violin, and the tiny notes gathered into a long and surging river. The sound of the water was full of ecstasy, as if every water droplet was clapping enthusiastically, dancing and singing.

Qin Jue was simultaneously infected by the cute behavior of playing the piano without speaking and the joyful and intense music, and he laughed out loud unconsciously.

Qin Yuqiao played the impromptu for several minutes passionately. When he opened his eyes again, his eyes had regained focus and were as bright as morning stars.

"I'm so happy!!...Ah woo!"

She subconsciously got up and rushed towards Qin Jue, forgetting that she was still barefoot in the slippery bathroom, and immediately fell into her sister's arms with her piano, and a small red mark appeared on the bridge of her nose and forehead.

Qin Jue laughed so hard that he caught a handful of little foxes that were having sex, and moved his slippers over for her to step on.

"I really want to go find the deputy team now!" Qin Yuqiao held up the violin and bow, "I suddenly feel very useful!!"

"What are you talking about? You are already very useful." Qin Jue rubbed her red forehead.

"Well, it's more useful this time!" Qin Yuqiao waved excitedly.

"Okay, okay." Qin Jue coaxed, "Super useful little fox, why don't you put on your clothes first?"

"(??.)/!…………"

The violin and bow were frozen in mid-air. Qin Yuqiao looked down, blushed and gathered up his bathrobe, "I forgot...!"

"What a little fool hhhhh" Qin was unkindly amused. While laughing, he stood up and pulled over a small trolley containing bath towels and a change of clothes.

Qin Yuqiao: "Woo."

It was rare that the usually shrewd and cunning little fox was so happy that she forgot about herself. Qin Jue couldn't help but persecute her in a malicious way.

"Okay, let's take a shower first. Generally speaking, it went very well, and there are some unexpected surprises." Qin Jue said gently, "Remember to let A Ran move out, it will be easy to lose control after a long time."

Qin Yuqiao nodded, with a little bit of shame and anger still remaining on his face. Qin Jue smiled and pinched her cheek.

After a while, the sound of the hair dryer came. Qin Jue, who was sitting on the sofa in the living room, saw the TV screen light up and said hello to his daughter with a smile.

"Is everything okay?" she asked.

"Well! The previous mental force field explosion was because Lili has been exercising her synesthesia ability during this period, and her mental power has increased a lot, so it happened to break through during the genetic optimization, which is a good thing!" Moriran said on the screen

Swimming around.

"Not bad." Qin Jue breathed a sigh of relief.

After a pause, she added: "Aran, let your grandma know, echo imaging for the blind... I guess it is another composite project, let's see how he arranges it."

Previously, Qin Jue and Cheng Zheng discussed letting Qin Yuqiao go to the Acoustic Research Institute of Qinyi Technology. Now that the little fox accidentally has new abilities, the plan should be adjusted accordingly.

"Okay -" Mori Ran spit out the snake letter, "But dad, why don't you tell grandma yourself?"

"..." Qin Jue coughed, "Children don't ask about adults' sense of ritual."

Moriran's snake tail coiled up into a question mark.

"You guys are so weird, that's great." She shook her head inexplicably and plunged into the lower left corner of the screen like a dolphin diving into water, quickly disappearing from the screen.

Qin Jue felt a little guilty as he watched his daughter leave.

The retribution came very quickly. She was persecuting the little fox just now, but in the blink of an eye, she was also being persecuted a little.

Man, it's really weird. We haven't seen each other for a long time. I don't know if it's because of the shyness of being close to home or something else. Since receiving the invitation letter, Qin Jue and Cheng Zheng haven't contacted each other again. Although they said they were busy, they were really busy.

But whether it is because they are too busy to have time or because they are avoiding it because of confusion, both parties involved know the answer clearly.

And then continue to maintain this damn tacit understanding...

"It's just like online dating." Qin Jue muttered.

Another thought, what is the general process of online dating? Go to the airport or station to pick up someone, have a meal, chat, go shopping and watch a movie, and then maybe go on a date in the evening...

Cough cough cough.

Don't make it sound like online dating is so immoral. There are so many innocent young lovers out there. Who like you can't stop thinking about that kind of thing.

Qin Jue complained silently in his heart and apologized for slandering those innocent lovers.

She belatedly heard Qin Yuqiao's footsteps and quickly raised her head.

"All done?"

Qin Yuqiao nodded, blinking and still a little confused.

Why was my sister's breathing sound just now dark orange... mixed with scarlet and light pink-purple? It felt like the kind of vampire who couldn't help but want to eat... Oops.

She patted her cheek sheepishly, I don’t know, the little fox doesn’t know anything.jpg

"Huh?"

"Ahem! It's nothing."

Qin Yuqiao immediately changed the topic, "Speaking of which, did it affect other people just now..."

"It's a power outage. Mingzi sent a message." Qin Jue shook his phone, "The time is short and the problem is not big. If you feel embarrassed, you can try mental training in the past two days to convey peace and tranquility.

He's spiritual force field covers the past, allowing the residents of this building to sleep more peacefully."

"Huh? Okay."

Qin Yuqiao's eyes lit up, "Can this kind of thing be done? Will it cause another power outage?"

"It won't happen if you control it well." Qin Jue said with a smile, "You used to be quite good at this."

Then he put away his cell phone, stood up and stretched:

"Come on! Go downstairs and do a few tricks. Let me see how your physical fitness is now."
