Chapter 441 Changing the World of the Blind

When learning knowledge, you should follow a filter from simple to complex. You can't solve the most difficult problems overnight. In this way, the result of greed will lead to easy setbacks, which will create an impossible feeling about the content to be learned, and finally give up.

Therefore, when learning programming, many examples start from the simplest. Only in this way can people be easy to understand and obtain a kind of spiritual encouragement and satisfaction, so that they will have the motivation to continue learning.

It was the same when Lin Hong trained Shu Xiaoxian.

At the beginning, he asked her to sense larger and closer objects, which would be relatively easy to recognize, so he established a belief that "I can do it" in his heart, and then gradually increased the difficulty. With the previous experience and confidence, it was very helpful for the greater problem of customer service.

One of the strategies formulated by Lin Hong for Shu Xiaoxian is comparison. Through the comparison of the two incomparable situations, let them distinguish the differences and remember them. For example, the comparison of object size, the distance, and the material of the object.

This kind of training is not that he can practice wherever he wants, but through careful consideration.

Shu Xiaoxian is a very smart girl. Although Lin Hong did not tell her in detail why she trained like this, she also realized that later, without Lin Hong asking her to do it, she could take the initiative to train herself.

When Si Qian and the nurse pushed the instrument in, Shu Xiaoxian had begun to walk around the room, and there were chairs, bedside tables and other obstacles in the open space of the room.

When Si Qian returned to the room, she happened to see her walking around the room, making a strange sound in her mouth.

She couldn't help but be slightly stunned. She was puzzled to see that she was walking straight towards a chair. When she was about to shout at Si Qian, she suddenly saw Shu Xiaoxian moving directly to the side and go around the side of the chair.

She took a few more steps, and there was a wall right in front of her. When she was dozens of centimeters away from the wall, Shu Xiaoxian stopped directly as if she saw it.

She turned around, turned to the door and said, "Mom, is that you? Well, who is the other one?"

When Si Qian heard her words, she was immediately excited. She immediately ran over excitedly, hugged Shu Xiaoxian, and quickly asked, "Xiaoxian, can you see it?"

As she said, she kept shaking in front of Shu Xiaoxian's eyes with her hands. Unfortunately, the agate-like eyes did not respond at all, and she still turned by herself.

Si Qian also realized at this time that she was too excited about Xiaoxian's words just now. Obviously, she couldn't see it, but she just sensed someone coming in. Si Qian also has some awareness of Xiaoxian's hearing. It is not difficult to hear someone coming in.

But what happened just bypassing the chair?

Thinking like this, Xiaoxian said happily, "Mom, my brother gave me a way to see things through the sound. I can now see the things in the room very easily."

"Oh?" When Si Qian heard the words, she couldn't help looking at Lin Hong doubtfully.

Lin Hong smiled and said, "It's an echo positioning skill that I accidentally thought about before, but now it seems to be quite useful. It can just assist the activities of the little fairy. After being proficient, it should be very convenient.

Si Qian couldn't help but be even more surprised when she heard Lin Hong's words.

Ecphonic positioning?

When she heard this word, her first reaction was to think of the sonar system, and then to think of bats.

"Mom, it's true! Let me show you!"

With

, Xiaoxian broke away from Si Qian's arms and walked directly in the room.

After all, she is an eight-year-old child. She has learned such magical skills, as if she has found her favorite toy. She can't wait to perform to her closest people and get their praise.

The little fairy was like a butterfly, walking briskly back and forth in the room at a slightly faster speed than before. Whenever she met an obstacle in front of her, she seemed to really see it. She dodged the past accurately and smoothly, and it was the same when she met the wall. Every time she met it. It has stopped and turned before.

On the surface, she is no different from a normal person now.

Si Qian was completely stunned.

Only then did she know that these things in the center of the venue were deliberately placed in order to let her do the test.

At the beginning, she was still a little worried that her daughter would be injured by touching the chair in the center of the venue. After all, Xiaoxian was too easy to get hurt. She was like a porcelain doll, hurt as soon as she touched it. However, slowly, she gradually let go of this hanging heart, and Xiaoxian's performance surprised and made her happy.

It's not just Si Qian, but also the nurse who just came in. Of course, she knows that the lovely daughter adopted by Director Si is a blind man. When she walks, she often has to pull Si Qian's skirt to dare to move forward. Otherwise, she can only stretch out a pair of small hands and touch and touch in front of her, which is slower than a snail.

When did she see Shu Xiaoxian move as fast as she is now?

Thinking of their conversation just now, she couldn't help but be very interested in the echo positioning mentioned by the handsome man who was ill.

How can blind people see things? Isn't that amazing?

Tears in Si Qian's eyes came out. She hugged Shu Xiaoxian and then said sincerely to Lin Hong, "Lin Hong, thank you!"

Lin Hong shook his head with a smile: "Xiaoxian is very cute, and I also like her very much. Since she calls me brother, I should help her."

"Are you... able to speak?" Si Qian looked at Lin Hong in surprise.

At this time, she realized that she didn't know when Lin Hong had regained the ability to speak.

"It has been restored for the time being, but we still need to find the reason." Lin Hong pointed to his head, "Your massage was very effective before, and it felt very good."

Si Qian's massage technology is indeed excellent. When she pressed it before, Lin Hong was surprised to find that her brain, which had been calm, seemed to be a little loose, which showed that her previous speculation was probably correct.

As soon as Si Qian heard him talk about his illness, she immediately paid attention to it. She took a look at the nurse who had not left beside her and said, "Huihui, I can come here. You go ahead first."

"Ah?" The little nurse was slightly stunned, and then nodded with a little disappointment, "Then I'll go out first. If you need anything, just call me directly."

She actually wanted to listen carefully to Lin Hong talk about the echo positioning, but she had to listen to the director's words, so she had to leave reluctantly.

When Si Qian heard Lin Hong talk about his condition, she immediately paid attention to it, put other things aside first, then found a small notebook, carefully asked Lin Hong for details, and then recorded it in the notebook little by little.

After completing this step, she began to fix the advancing instrument, and then pasted the detection electrode to Lin Hong, and began to record his electroencephalogram and electrocardiogram.

After finishing these things, she turned her attention to the "e Echo Positioning" technology mentioned by Lin Hong before.

"Lin Hong, tell me carefully about the echo positioning you just mentioned. In such a short time, Xiaoxian can actually do this step. I have to say that you gave me a great surprise again." Si Qian looked at the man in front of her with complicated eyes.

"This technology, as you should know from the name, is actually derived from the echolocation of animals. It is to judge whether there are obstacles in front of you by echo. You should have noticed that when Xiaoxian is walking, she needs to make a sound in her mouth, just to make an echo.

Si Qian nodded: "Well, it's just that I can't figure out that people can do this? This... seems difficult, doesn't it?"

Echo positioning is not a new technology. Bionics has been very good in this regard for a long time. The sonar system on the submarine has not known what stage this technology has been developed. But why has no one ever mentioned the use of this technology on blind people?

"It's actually not very difficult." Lin Hong organized the language and said, "I guess there must be a blind person who has discovered such a technology, but it has not been made public. The plasticity of the brain is actually very strong. If blind people can't see, the corresponding hearing will be strengthened. Their sound ** sex is much higher than that of normal people. For them, it is just pediatrics.

Speaking of this, Lin Hong paused for a moment. He looked at Shu Xiaoxian, who stayed quietly and listened to their conversation obediently, and then continued, "Actually, I didn't expect Xiaoxian to learn so fast. This may be related to her strong hearing and memory, so she mastered this skill in just over 20 minutes. However, according to my estimation, if others want to master this skill, they may need at least a week of training to establish a conditioned reflex.

Hearing this, Si Qian's beautiful eyes couldn't help but light up: "You mean that others can also master this skill?"

"Of course, there is no threshold for this. Basically, as long as you have a certain amount of hearing. Even normal people with better hearing can master this skill after training. What he said was not open-minded, but had his own test parameters. Although he found that (Bookstore www.shushu5.com, the fastest update www.shushu5.com) was found through the superbrain, after detailed analysis, he found that in fact, to master this skill, there is no need to be too high requirements, all that is needed. It's just learning and effective training.

"I already have a preliminary idea. After being discharged from the hospital, I will set up such a research group in the company to conduct research on this area to see if this technology can be promoted among the blind. If it can be done, it can also be regarded as a welfare for blind people all over the world. Lin Hong has always wanted to change the world through his own efforts, and this kind of thing is actually a kind of change in the world.

Change the world, let's start with changing the world of the blind! Lin Hong said to himself.
