When you see the engineering prototype, you know how important it is to have a sufficient talent pool.

Not to mention the test of the chip itself to the tape-out, after the chip is designed, to embed the chip into the motherboard, a team is required to redesign the circuit layout of the motherboard. Sometimes a small change requires countless changes to the design drawing, let alone a big change like embedding a chip.

At the same time, hardware cannot exist without software.

In order to realize the chip function, it is also necessary to make the operating system able to support it, which requires several engineering teams to supplement the system functions and continuously test the compatibility of hardware and software.

If Wang Yufei is allowed to do all of this alone, of course, it is not impossible to complete, but it is impossible to produce results so quickly.

It seems that this chip itself uses the technology accumulated by Huaqing Brain Computer Laboratory for many years.

So even if this engineering prototype only implements a few simple functions, it is enough to amaze the insiders.

For example, brainwave unlocking.

By clearing the previously bound brainwaves, and then rebinding the tester's brainwaves, and silently thinking about the number of the boot in the brain, you can directly turn on the phone.

Although the technology is not mature, and the time-consuming is not as fast as fingerprint unlocking, it is stronger than fingerprint and facial recognition unlocking in terms of security.

For the time being, there is no technology that can fake the frequency of a person's unique brainwaves.

Another feature is the silent alarm.

This is also the original intention of Wang Yufei to design this brain-computer chip.

Reciting the alarm number of 110 silently in the bottom of your heart can automatically trigger the dangerous environment working mode of the brain-computer chip, directly adjust the mobile phone to silent mode, and dial 110 directly, after dialing, the mobile phone will vibrate slightly, and in silent mode, the hands-free function will be automatically turned on.

For the time being, these are two of the most useful features.

To add more features, you need the cooperation of software developers.

The interface is published by Weihua, and the software developer provides the corresponding functions within the software.

Weihua's own software has been able to achieve some simple functions, such as using brainwave control to automatically turn pages on the reading software launched by Weihua, realizing contactless backward and fast forward on Weihua video, and quickly taking screenshots.

It may seem like a few mediocre features, but in the eyes of those in the industry, it is definitely a remarkable achievement.

One could even say about the achievements of the Nobel Prize.

The only thing that makes Wang Yufei feel dissatisfied is still the problem of the accuracy of brainwave recognition.

Although the accuracy rate can reach about 90% according to the current results, this obviously does not meet the requirements of consumer level.

"Maybe there's a need for a wearable device that can amplify brainwave signals. ”

After Lu Yuxin tried to control the engineering prototype with brainwaves for ten minutes, and then talked about his own experience of using it, Wang Yufei gave a conclusion.

"The lab had previously designed a frame for collecting brainwave signals, which could be used with a brain-computer chip with an accuracy rate of more than 99 percent and a faster response time. Cao Luping said.

"Frames?"

"Yes, it was also a product that was inspired by cochlear implants and designed on a whim. The exterior is similar to a regular frame, with two electrode contacts where it touches the ear, wires inside, and a signal generator on each side and in the middle of the frame. At that time, we wanted to use a simple device that could directly implement brain-computer language input. It's typing with brain waves. ”

"What about the production cost of this frame?"

"If you don't count R&D expenses, it's not expensive. It's even cheaper than many of the regular frames sold in stores. The cost of the laboratory is about 100 yuan, and if it is mass-produced, it should be able to control it at 60 or 70 yuan?"

"Will the lenses make a difference?"

"It doesn't have much impact, it can be wet, but it can't be soaked in water for a long time, so you just need to pay attention to the cleaning method!"

"Then this frame in the laboratory can be used with a brain-computer chip!" Wang Yufei's eyes lit up.

"Theoretically, but if your eyesight is fine, who wants to wear glasses when you're fine?" Cao Luping shook his head and said.

"It's just an option, and there is room for improvement in brain-computer chips. But if you can do more with this frame, I think there are still a lot of people who will be willing to pay for it!

"I have to apply!"

"Congratulations, Senior Brother Cao, you have found another profit growth point for the laboratory!"

......

Wang Yufei and Cao Luping started a discussion on the engineering prototype of the brain-computer chip and its application in technology.

The conversation was very pleasant, and even the excited Gao Deyuan couldn't interject.

Some are faceless.

So Gao Deyuan simply didn't bother to pay attention to the two who were chatting hotly.

I found two teacups by myself, made a cup of tea for him and Lu Yuxin, drank it, and then looked at the two proud disciples, pointing at the engineering prototype and discussing some professional issues.

For example, how to increase the accuracy and speed of data collection by adding all-round built-in wires, how to update the algorithm of brain signal translation, which can make simple control faster, and the feasibility of docking external devices with brain-computer chips......

Then it was more than two hours.

Cao Luping also took a notebook and recorded some of the key points discussed by the two.

Obviously, I think that Wang Yufei said a lot of things that inspire him very much.

Of course, Wang Yufei also silently wrote down some of Cao Luping's inspiring suggestions and achievements, but he didn't need a notebook.

I have to say that the two cooperate very well, Wang Yufei has a talent that Cao Luping can hardly achieve, but Cao Luping has many years of experience in front-line research in this field that Wang Yufei can't get at his fingertips.

Exactly complementary.

So when they left the lab, both of them were satisfied.

"Yu Xin, Senior Brother Cao is a good person!" Wang Yufei sighed on the way back to the dormitory.

"That's pretty good, and then?"

"I want to help my brother!"

"Help him with what?"

"Help him find a girlfriend, today he is still complaining that he doesn't have a girlfriend in his thirties!" Wang Yufei said of course.

"Do you know a lot of girls?" Lu Yuxin asked, tilting her head to look at Wang Yufei.

"No, no, I didn't think about introducing him to a girlfriend. I'm thinking about whether we can design a software specifically for a professional talent like Senior Brother Cao, or a software that can be used with brainwave chips, and a software that can help them overcome social barriers!

"Huh, let the phone say hello and add friends by itself?"

Lu Yuxin blinked, this idea seems to be a little novel!
