Chapter 383 Retina Screen

In order to successfully simulate the scene of sensory cells after seeing the image on his retina, Lin Hong spent two days exploring, and finally displayed "HELLO SUPER BRAIN" on his retina "display".

He actually wants to use Chinese, but it's a little too complicated.

An advantage of English is that all the characters that make up the words are only 26. As long as the encoding of these 26 characters is completed, it means that the English display is completed.

Chinese is different. Its most basic components are indeed only a limited number, but they are not a simple combination, and simple coding alone is not enough for this task.

I have to admit that English has its natural advantages in the computer field.

"Looking" at the words "Hello, super brain" that appeared in front of him, a smile appeared on Lin Hong's face again.

He couldn't help shaking his hand a few times in front of his eyes, and his hand shook behind the word.

As the head rotates, the words that appear in front of you also follow the rotation. Compared with the position of the eyeball, it is completely fixed.

Lin Hong closed his eyes again, which is the same effect, and due to the lack of interference from outside light, the pattern displayed at this moment is clearer.

After experiencing it back and forth through various methods, Lin Hong began to fine-tune the display effect of the text.

He found that in addition to the function of the usual display, it is also necessary to add a parameter to the display element inside, that is, the distance.

The scene seen by people's eyes has a sense of distance. The picture displayed by the three-dimensional and ordinary display is a flat one. Lin Hong just wanted to display it before, and did not consider this effect at all.

After experiencing it in this way for a period of time, I found that the words in front of me were like a spot in the eyeball, sticking to the eyeball, which felt strange.

Therefore, he began to fine-tune the simulated light-sensing cells. The state of the light-sensing cells in the two eyes is somewhat different, not exactly the same.

It is a continuous test and experiment, which has a relatively satisfactory effect.

When he "looks", the picture displayed in front of him is about the same as a computer display screen in the front 50 centimeters. If it is a little farther away, the display area will be larger.

He fixed this parameter for the time being, and then consider adding a function that can be automatically adjusted according to the size of the content at any time.

The display resolution of this retina screen is super high. Compared with the resolution of this retina screen, the resolution of 640*480 pixels popular on the market is simply different. Considering the compatibility problem in the future, Lin Hong has only designated a small area to limit the resolution to it for the time being. Four times the size, that is, 1280*960 pixels.

In this way, the characters displayed on the Retina screen are clearly visible and quite comfortable.

Although the limit can display characters on it, there is no system installed in the eye of heaven now. This situation is a bit similar to electrical engineers. They directly use manual methods to spell out the corresponding patterns on the display, which only realizes the corresponding interface and structure.

If you want to be able to display content and even images, videos and other materials on the retina screen at will, you must also have supporting software support, and to run these software, you must have a fully functional super brain system.

Lin Hong has been in his laboratory for a long time these days in order to realize the computer to transfer data to the brain and the function of retina display. His mother Feng Wan came to his room many times to ask if she was stimulated by the last time she talked to his grandfather.

It's really a little long to stay in the room. Lin Hong didn't continue to work during the day.

After breakfast, he said to Pan Pan and Xia Tian, "Don't go out today. Let's do business."

"I've been waiting for your words for a long time." Pan Pan suddenly refreshed his spirits.

Summer also said, "Yes, these days, we go to the market every day, and we are a little tired of it."

These days, the two of them have not only traveled the whole Zhongguancun, but also visited the customers of Bei J.

In fact, the two of them have been thinking about this matter for a long time. They have been here for a long time. The company still has something to deal with. If Lin Hong doesn't do anything, they will consider going back to deal with things first.

Lin Hongxian called him according to the phone number given by Xu Zhizhong before. After receiving Lin Hong's call, he was very happy. Hearing him say that he had made the prototype of the real-time operating system he mentioned last time, he was very surprised and let them go there directly.

Xu Zhizhong's unit is an Air Force Radar Research Institute under the First Aviation Academy. He is the director of this institute.

He still attaches great importance to Lin Hong's visit. Originally, there was a more important meeting this morning, but it was postponed because of Lin Hong's phone call, waiting for the arrival of Lin Hong and others in the institute.

Xu Zhizhong is not a person who tends to be possessed. He did so because he was really looking forward to the real-time embedded system mentioned by Lin Hong, not because of his grandfather's relationship.

Xu Zhizhong is now reading a scientific research report submitted by the following scientific research team in the office. At this time, Feng Anguo, the director of the office, knocked on the door and came in.

"Sont. Director, why was the meeting this morning postponed? Is there a new change?" As the director of the office, Feng Anguo is responsible for the administrative work organization of these daily meetings. The meetings that had been prepared were suddenly postponed, but he did not receive any notice in advance. He had to come and ask about the situation in order to better arrange the work.

"Actually, it's not a big deal. The main reason is that a friend is coming this morning.

Xu Zhizhong explained, "This meeting will be the same until tomorrow. It happens that a few comrades have some materials that have not been prepared yet, so let them be fully prepared."

"That's it."

Although Xu Zhizhong's reasons are relatively sufficient, Xu Anguo knows that such a meeting, generally according to his rigorous temper, will not casually postpone such a meeting.

He couldn't help but be very curious about the people coming today.

He asked, "Is there someone from above coming today?" Do I need to make special preparations?"

Usually, it is not that there are no people from higher units to come down to play the autumn wind. In the name of inspecting the work, they come down to eat and drink. Although they are disgusted with this, they have to entertain them. After all, the people who can come down are not simple. If because of these Things offended the other party, and maybe they will get into trouble at the critical moment.

This phenomenon is common in many units, so basically there are special hospitality funds in the units.

This kind of work is also within the scope of Feng Anguo's work, so it is not abrupt for him to take the initiative to intervene.

"No, it's not a superior unit, but a person from a cooperative unit, and it's also a friend I've known for many years. They came here this time and brought their latest research results.

At this point, Xu Zhizhong suddenly saw the ore radio in his window. He remembered that he had told him about Lin Hong, so he said, "Well, he is the student I told you about, that is, the maker of this ore radio."

"Oh?" When Feng Anguo heard this, he suddenly became interested. He had admired this proud disciple of Director Xu for a long time. This ore radio made him greedy for a long time.

"Station, when he comes, you have to help me introduce him. I'm still thinking about your ore radio. If there is a chance, I have to ask him to give me the whole one."

"Haha, there must be no problem with the introduction, but I can't guarantee the ore radio."

After Feng Anguo left, Xu Zhizhong immediately remembered one thing and thought, "I heard that this Feng An country has a lot of background. Bei J Feng's surname is relatively famous, and there should be only one Feng family. What is the relationship between Feng Anguo and Feng Lao?"

Xu Zhizhong is not concerned about these intricate relationships in the institute. In addition, Feng Anguo is also relatively low-key in the institute and has never told others about his family background, so he does not know that Feng Anguo is the second son of Feng Yuanzheng, and Xu Zhizhong and Feng Yuanzheng have only had a relationship. Such a person Even he can't see it casually. If it hadn't been for Lin Hong's affairs, he would have no contact with the other party at all.

"If this is the case, Feng Anguo should also know Xiao Hongcai. Why didn't he know Xiao Hong's name?" Xu Zhizhong shook his head and denied his conjecture. He can't remember at all. In fact, he has never mentioned Lin Hong's name to Feng Anguo.

After more than an hour's drive, the van rented by Lin Hong and others sent them outside the wall of the Radar Research Institute, and then they were not allowed to enter and stopped by the guards at the door.

This is a military heavy place, and the idle people all stopped. After the driver of the panel car got in front of the car, he left.

"This is a military area. If you have nothing to do, please leave." The guard looked at Lin Hong and others and said.

"Hello, comrade, we are here to find Director Xu."

"Shang Xu?" The guard looked at it again and saw that they were carrying a notebook and a car full of electronic devices, which was a little high-tech, but the three of them were too young and suspicious.

"Do you have any credentials?" The guard said patiently that he did not receive a notice that someone was coming. Usually, if there is an appointment, they will have a record here. The credentials he refers to documents such as introductory. Although this kind of thing is rare outside, it is often seen in the system or in the army.

Lin Hong said, "No. But I can call him."

He didn't expect to be blocked at the door, but he could understand. After all, this is the Air Force Radar Research Institute, which has a high level of confidentiality.

Just then, a middle-aged man came out of it. Seeing this scene, he came over and asked, "What's going on?"
