Twilight swept across the sea and finally landed next to the hotel building.

There was a minibus, and a group of people were queuing up to get on the bus.

Seeing that the students he brought were all going up, Ji Rong himself also stepped forward.

"Professor Ji!

Turning his head and looking at the back of the car, it was Atletico who greeted him.

At this time, he had already changed his outfit, fruit-printed short sleeves, light-colored five-quarter pants, and a straw hat, full of tropical style, looking no different from those tourists outside.

Not only him, but everyone else around him was dressed similarly to him, and they all wore the same flat hat, looking very neat.

Quickening his pace and walking over, Ji Rong sat next to Atletico Madrid.

Waving to drive, Atletico smiled and said to him: "You're early." In fact, you can play for a while, and it's too late to wait until 19 o'clock to set off. ”

"That's not good!" Ji Rong waved his hand, "You are all gone, and when I get down at 7 o'clock, I have to pay for a ticket out of my own pocket, isn't it cost-effective?"

The dignified distinguished professor of Ludao University, it is naturally impossible to take a taxi without money, and this is just talking. Looking at the top of his Atletico head, Ji Rong asked curiously: "What's going on? It's almost dark, why do you still wear hats to go out?"

"Naturally, it's useful," Atletico smiled, "Brother Rong, do you want to have one, it's free!"

Teacher Ji stood up and said that I was not fooled: "There is no free lunch in the world, it is not sent early or late, and at this time, there must be a conspiracy." ”

"There's no conspiracy," Atletico chuckled and shook his head, "but this thing does have something to do with our pre-dinner activities, and we'll need it later." ”

Since people didn't say it, Ji Rong didn't ask, took out the plastic box containing the black jade concept machine from his bag and returned it to the other party, "By the way, this will be returned to you!"

Atletico took Zhu Lingling, who was handed to the front seat, turned his head and asked, "How is it?"

"Black, very black!" Ji Rong read out a string of cool new features like a few treasures, "C4 processor, NPU, 4K butterfly screen, ceramic body, face recognition, remote pickup, not to mention, after all, other machines have more or less of them." I really didn't expect you to play so big, in addition to the ultrasound fingerprint and the under-screen camera, you actually did directional sound, can you say that you are all monsters?"

"Well, this is a concept machine after all, and of course it can be loaded with advanced technology regardless of the cost. ”

The so-called directional sound is a directional sound, some of which are like the condensation of family dialect into a line, and the sound is transmitted into a dense, only people in the transmission direction can hear the sound, but people in other areas are not aware of it.

Roll a horn with cardboard, you can make the simplest directional sound equipment, of course, the effect is also the worst. Further optimize the shape and add an acoustic lens structure, and the effect will be much better. But if you want better performance, you need to use more advanced technologies, and ultrasound modulation and demodulation technology is one of them. It loads the sound signal onto the ultrasonic wave and projects it, and transmits the sound with the help of the directivity of the ultrasonic wave, as long as the modulation is appropriate, the low-frequency content in the sound will be demodulated by itself and heard, while people in other directions will not feel it throughout the whole process.

In the online news, hundreds of residents were harassed by square dance aunts, and raised 260,000 yuan to buy a "loudspeaker" placed on the roof of the building to disperse the crowd in the square, and its core technology is this.

The mobile phone speaker does not need to be as powerful as the former, and the distance is tens or hundreds of meters, but the actual difficulty is only high. No way, the mobile phone is too small, and the designer only left a microhole for the speaker in order to look good for "face", and the difficulty of making a dojo in the screw shell can be imagined.

Fortunately, the bee has finally done it, with the blessing of directional sound technology, the mobile phone can achieve long-distance sound with less power, and it can also effectively avoid voice calls, especially the problem of sound leakage and microphone echo during video conversations. Ji Rong only knew a little about it, and he was impressed by this technology, he had studied humming search technology before, and he had a certain understanding of the acoustic field, so he naturally knew how difficult this thing was.

Seeing that Atletico Madrid said it lightly, he was a little excited, "How can it be so simple? I know how difficult these things are, and they can't be done if you want to do it." Which of those senior tuners and sound engineers out there is not a core employee of the audio and headphone company? Tell me, where did you find people?"

The color is caused by the mixing of light waves of different frequencies, and the sound is caused by the mixing of sound waves of different frequencies.

The final object of light color and sound is the human eye and human ear, which is inevitably affected by the subtle differences in the structure of the eyes and ears and even the state of mind of the environment. The same set of light waves and sound waves, falling on different people, will produce different feelings, and then there are all kinds of "metaphysics", you think it's okay, I think it's very bad, and it's difficult to reconcile people to make people helpless.

When tuners and sound engineers adjust equipment to modify sound sources, they are actually choosing for consumers to listen to. Only by maximizing compatibility with the tastes of the target users can we ensure that the product is accepted by more people. Without them, even if you make audio products with excellent indicators, it is still difficult to win the love and even trust of users in the end.

"It's no one else," Facing Ji Rong's question, Atletico Madrid indifferently pointed back to himself, "It's just below." ”

"Huh?" The former was slightly stunned, but quickly reacted, if it was Atletico Madrid, it was not unacceptable, this guy's talent in all aspects is just a middle-class appearance, but he has a strong learning ability, hands-on ability, and single-handedly led the design work of the bee operating system, bee processor, butterfly screen, etc., and now with the directional sound speaker, it seems that there is nothing wrong.

After glancing at someone deeply, Ji Rong sighed in a tone that was more powerful than others: "You are really capable of anything! I don't know what the school thought at the beginning, and it didn't pull you back as a visiting professor." ”

"The dean did look for me, but I pushed it down, my level is limited, my education is too low, and I am afraid of misleading people's children. ”

"Are you still at a low level?" Ji Rong glared at a certain pretending convict in annoyance.

The School of Information submitted so many papers (especially those published in foreign journals in Chinese to English), and finally 4 papers were included in the CVPR, and none of them entered the ORAL (oral) stage, while the Bee Research Institute had 3 ORAL.

This year's CVPR included nearly 800 papers in the field of image pattern recognition, but only 144 were invited to give short highlight speeches, and only 70 were qualified to give long oral speeches.

"Of course," Atletico nodded, "I'm just a pretty good application engineer, and without you experts to create a theoretical direction, we would have been blind." ”

"I'm older than you, and I haven't published as many papers as you. ”

At this moment, the bus suddenly stopped, interrupting Ji Rong's self-humility and praise.

Turning his head to look at the side of the road, he was amazed to see a hair salon, "This is it?

Atletico nodded calmly, "We're going to get a collective haircut." As the old saying goes, 'If you're full, you won't shave your head, and if you're hungry, you won't bathe', so make your head before you eat. ”

"Poof!" Professor Ji burst out laughing at the time, "Isn't there a hairdresser in China?

As a pure handicraftsman, the labor efficiency of barbers is difficult to improve due to technological progress, and the cost cannot be diluted because of technological dividends.

However, in addition to the inflationary environment, the level of urban income also has a significant impact on the price of haircuts. No matter how much the price of domestic barbers rises, they can't be compared with developed countries in Europe and the United States, not to mention that it is still a famous island tourist city of Honolulu. In terms of the input-output ratio alone, it is not worth it to go here for a haircut, especially when Atletico Madrid says "shaving the head", whether the bald head is beautiful or not, and it doesn't all depend on personal appearance?

Atletico was also a little embarrassed, but still explained: "I didn't have a plan to shave my head before, and then there was something wrong with the brainwave helmet, so I had to try to fix it in this way." ”

The CVPR Organizing Committee is very interested in the paper "Synaesthesia Synesthesia Synesthesia Technology Implementation Based on Novel BMI Interface" of the Bee Research Institute, and the author team was invited to give a long oral lecture here. The Bee Research Institute pushed the boat down the river and brought a batch of developed version of the "Heart Ring" equipment over, intending to take the opportunity to sell it to academia and industry.

However, the afternoon experience encountered problems, and many people complained that they were unaware of it, and even suspected that the Bee Research Institute was cheating academically.

Hearing these reasons, Ji Rong couldn't help but get nervous, stared at Atletico and asked, "You can't really fake it, right?"

"How is it possible?" Atletico shook his head, stood up and motioned for the other party to get out of the car quickly, and then said as he walked: "It's a problem with the 'internal force meridian' demo used to demonstrate, foreigners don't have the concept of meridian internal force in their hearts, it's hard to imagine those things, and the effect is naturally much worse." ”

Ji Rong is a 34-year-old distinguished professor, and his IQ is naturally online, and he walked into the salon behind Atletico Madrid, "Without hair blocking, brain electrodes can send and receive stronger signals, thereby improving the final effect." So you came up with the idea of shaving your head, shaving your head yourself is not the goal, the key is to induce others to shave their heads to participate in the experiment?"

"That's right," Atletico nodded, "The domestic team is urgently making a new demo demo, and this time we have prepared the 'cannibal zombie' and 'angel holy light' that foreigners like, which should be able to significantly improve the perception in the body." ”

Hearing him say this, Ji Rong relieved himself and secretly breathed a sigh of relief, "That's good, these things are very appetizing to others as soon as they hear them." By the way, doesn't it mean that the resolution of BMI synesthesia is very poor, and it can only make users feel the blurred line information? ”

"If it's only 'Heart Ring 2', that's true," Atletico nodded and shook his head, "but what we're bringing this time is a full-featured set that integrates a headset and a sensor suit, but there is no such problem." ”

Ji Rong nodded, then remembered something again, and threw out two questions: "Do all those who wear hats have to shave?

"No, it's all voluntary, all hats are worn just to stay in formation. ”

"What about you?"

Atletico touched his hair a little reluctantly, "Well, I'm naturally going to play an exemplary role." ”

"Haha!" Professor Ji couldn't help it anymore, took out his mobile phone and said with a smile: "Atletico led the Bee Research Institute to cut the invention aspirations, I must take a picture and post it on the Internet." ”

"Whatever you want," Atletico pretended to be helpless, waved his hand to signal the others to get it first, and then said: "Let me take a look after the shooting, there are some things that can't be sent out." ”

"Okay, no problem, anyway, I'm not ready to post it now, there must be a bunch of people on Weibo who are busy lighting wax. ”

One of Professor Su's research results is "social media public opinion forecasting", and he naturally understands these techniques very well.

"Well, it will be fine in a few days," Atletico nodded.

Immediately afterwards, he also took out his mobile phone, opened the domestic version of the scarf and looked at the popular rankings.

It is now 18 o'clock on the 20th Hawaii time, and it is 12 o'clock on the 21st in China. So unsurprisingly, Candle, .p. also captured the scarf and Weibo.

Under the pain of the egg, he ran to see the number of hot search words in Honey Search, and then found a very fact, the popularity of the deceased "Chester Bennington" has surged 10 times from 200+, and the popularity of his band "Linkin Park" has jumped from 1500 to 100,000. It's only noon, and by 21 or 22 o'clock in the evening, the heat can be even more.

Although these numbers can only represent Misou users, they also reflect a trend: today, we are all rock and roll fans!

casually glanced at the analysis articles that were quickly released by various self-media, and Atletico Madrid also followed the trend to remember the rock star who was defeated and killed by himself.

Instead of saying "Transformers and League of Legends wouldn't be complete without the Linkin Park song", he simply talked about the incident he encountered when he checked into the hotel in the morning, and finally put a photo with the lost music fan, and he was all gone.

Seeing him put down his mobile phone, Ji Rong suddenly grabbed his arm.

"How?"

"I've decided!" Professor Ji made up his mind, "I'll shave my head later!"

Of course, Atletico Madrid understood that the other party wanted to join the experience, but they still made a little joke: "You think about it? ”

Hearing his words, Ji Rong immediately smiled and asked to confirm, "You also watch 'One Punch Man'?"

"I have learned a little, as the source of the creative industry chain, comics naturally need to pay attention. ”

"Are you going to harm Saitama again?"

Atletico Madrid's face was full of black lines, "We have official authorization, excellent picture quality, full dubbing, gorgeous special effects, no jams, no collapse, how can it be said to be a scourge? You are slandering!"

Professor Ji snorted very lightly: "The adaptation of domestic mobile games is recognized by the world, and the mobile game of Bee You is just a tall man in the, so do you still use me to slander me?"

"That's because you don't have the right mentality," Atletico explained with a smile, "God pretending to be a god card or something, just appreciate it as a high-end figure, you can only be happy if you do what you can, and forcing it will only increase the trouble." ”

"Hey, how can it be so easy?" Lao Ji shook his head, and was about to ask this guy for money, but someone came over there, but he was ready to finish it, and asked the boss to shave it first.
