Chapter 383 Retina Screen

In order to successfully simulate the scene after the sensory cells see the image on his retina, Lin Hong spent two full days exploring, and finally displayed the "hello_super_brain" on his retinal "display". Pen % fun % Pavilion www.biquge.info

He actually wanted to use Chinese, but it was a little too complicated to do.

One of the advantages of English is that there are only 26 characters in all the words that make up the words, as long as the encoding of these 26 characters is done, it means that the English display is completed.

Chinese, on the other hand, has only a limited number of basic elements, but it is not a simple combination, and simple coding alone cannot do this job.

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

"Looking" at the words "Hello, Super Brain" that appeared out of thin air in front of him, a smile appeared on Lin Hong's face again.

He couldn't help but reach out and dangle it in front of his eyes a few times, his hand shaking behind the words.

As the head turns, so do the words that come to mind, and they are fixed in relation to the position of the eyeball.

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

After experiencing this 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 usual function of the display, it was also necessary to add a parameter to the display element inside, that is, distance.

The scenery seen by human eyes is distant and three-dimensional, but the picture displayed by an ordinary monitor is a flat one, and Lin Hong only wanted to show it before, and he didn't consider this effect at all.

After experiencing this for a while, I found that these words in front of me were like a spot in the eyeball, sticking to the eyeball, which felt weird. 《》

So, he began to fine-tune the simulated light-sensing cells, and the state represented by the light-sensing cells in the two eyes was different, not identical.

It was another period of continuous testing and experimentation, which led to a more satisfactory result.

In his "look", the picture displayed in front of him was about the same as a computer display screen 50 centimeters in front of him, and the distance was a little farther, and the area that could be displayed was larger.

He fixed this parameter for the time being, and later considered adding a feature 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, and the resolution of those 640*480 pixels that are popular on the market now is 108,000 miles different from the resolution of this retina screen.

Considering the compatibility problem later, Lin Hong only demarcated a small area for the time being, limiting the resolution to four times its 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, but there is no system installed in the current Tianyan, this situation is a bit similar to an electrical engineer, directly using a manual way, spelling out the corresponding pattern on the display, but the corresponding interface and structure are just implemented.

In order to be able to display content and even images, videos and other materials on the retina screen as you like, you must also have supporting software support, and to run these software, you must have a well-functioning superbrain system.

Lin Hong has been spending a little time in his laboratory these days in order to realize the function of transmitting data from the computer to the brain and the display of the retina screen, and his mother Feng Wan has come to his room many times to ask, and is worried about whether he was stimulated by the last time he talked to his grandfather.

The time spent in the room was indeed a little long, and Lin Hong did not continue to work during the day.

After breakfast, he said to Pan Pan and Xia: "Don't go out today, let's go and get down to business." 《》”

"I've been waiting for you for a long time." Pan Pan suddenly perked up.

Summer also said: "Yes, these days, we run the market every day, and we are a little tired." ”

These days, the two of them have not only run the entire Zhongguancun, but also visited all the customers of Beij.

The two of them had actually been thinking about this matter for a long time, they had been here long enough, the company still had things to deal with, and Lin Hong didn't make any moves, so they considered going back to deal with things first.

Lin Hong first called him according to the phone number Xu Zhizhong gave before, and the other party was very happy after receiving Lin Hong's call, and when he heard him say that he had made the prototype of the real-time operating system he said last time, he was immediately very surprised At the same time, let them go directly.

Xu Zhizhong's unit is an Air Force Radar Research Institute under the First Academy of AVIC, and he is the director of this institute.

He still attached great importance to Lin Hong's visit, and there was originally a relatively important meeting this morning, but it was postponed because of Lin Hong's phone call, and he was waiting for Lin Hong and his arrival in the office.

Xu Zhizhong is not a person who tends to be inflammatory, and he does this because he is really looking forward to the real-time embedded system that Lin Hong said, not because of his grandfather's relationship.

Xu Zhizhong was reading a scientific research report submitted by the following scientific research team in his office at this moment, when Feng Anguo, the director of the office, knocked on the door and walked in.

"Director, why was this morning's meeting postponed? Is there a new change? Feng Anguo, as the director of the office, was in charge of the administrative work organization of these daily meetings, but the meeting that had been prepared was suddenly postponed, and he was not given any notice in advance, so he had to come over to inquire about the situation in order to better arrange the work.

"Actually, it's not a big deal, the main thing is that a friend is coming over this morning." Xu Zhizhong explained, "This meeting will be the same tomorrow, and there are just a few comrades who have some materials that are not ready, so let them be fully prepared." ”

"That's right."

Although Xu Zhizhong's reasons are relatively sufficient, Xu Anguo knows that this kind of meeting, under normal circumstances, according to his strict temper, will not casually postpone such a meeting.

He couldn't help but feel very curious about the person who was coming today.

He asked, "Is there someone from above coming today?" Should I make a special preparation? ”

In normal times, it is not that there are no people from higher-level units who come down to fight the autumn breeze, in the name of inspection work, come down to eat and drink, and their subordinate units, although disgusted by this, have to entertain, after all, the people who can come down are not simple, if they offend each other because of these things, maybe when they will stumble on them at a critical moment.

This phenomenon is common in many units, so basically there is a special entertainment fund set aside in the unit.

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

"No, it's not a superior unit, but a person from a cooperative unit, and at the same time a friend of mine who has known me for many years. They came over this time and brought their latest research results. ”

Speaking of this, Xu Zhizhong suddenly saw the ore radio in his window, and remembered that he had told him about Lin Hong back then, so he said: "By the way, he is the student I told you, that is, the maker of this ore radio." ”

"Oh?" When Feng Anguo heard this, he was immediately interested, he had admired this proud protégé of Director Xu for a long time, and this ore radio had made him covet it for a long time.

"Director, when he comes, you have to help me introduce him, but I'm still thinking about your ore radio, if I have the chance, I have to ask him to give me the whole one."

"Haha, the referral must be fine, but I can't guarantee the ore radio."

After Feng Anguo left, Xu Zhizhong suddenly remembered something and thought: "I heard that this Feng Anguo has a very good background, and the surname Feng in the north is more famous, there should be only one Feng family, could it be that Feng Anguo has anything to do with Feng Lao?" ”

Xu Zhizhong didn't care about these intricate relationships in the institute, and Feng Anguo was relatively low-key in the institute, and he had never told others about his family history, so he didn't know that Feng Anguo was Feng Yuanzheng's second son.

And Xu Zhizhong and Feng Yuanzheng only had a one-sided relationship, such a character, even he couldn't see it casually, if it weren't for Lin Hong's matter, he wouldn't have had anything to do with the other party at all.

"If that's the case, Feng Anguo should also know Xiao Hong, why didn't he know Xiao Hong's name when he heard it?" Xu Zhizhong shook his head and denied his conjecture. He couldn't remember it at all, in fact, he had never mentioned Lin Hong's name to Feng Anguo.

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

This is a military stronghold, and the idle people all stopped, and the driver of the panel car got the front of the car and left in a smoke.

"This is a military stronghold, if it's okay, please leave." The guards looked at Lin Hong and said.

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

"Director Xu?" The guard looked again, and saw that they were carrying a notebook and a small car full of electronic devices, which was a bit high-tech, but the three of them were too young to arouse suspicion.

"Do you have any credentials?" The guard said patiently, he didn't receive a notification that someone was coming, and usually, if there is an appointment, they will have a record here. By credentials, he refers to introductory documents, which are rare outside, but are often seen in the system or in the military.

Lin Hong said: "No. I can give him a call, though. ”

He didn't expect that he was actually blocked at the door, but he could understand it, after all, this is the Air Force Radar Research Institute, and the level of secrecy is very high.

At this moment, a middle-aged man walked out of it, and when he saw this scene, he came over and asked:

"What's going on?"
