After an hour's traffic jam, before the rush hour, Hao Yun finally arrived at the brain computer interface research institute in Chengnan high tech park.

To be honest, he really didn't understand the connection between augmented reality and brain computer interface technology.

No matter what you think, the former should belong to the category of display technology, while the latter obviously has nothing to do with display technology.

And when it comes to augmented reality

It doesn't seem to be a particularly novel thing.

At least not in this world.

According to Hao Yun, the technology has been used in the military field as early as 50 years ago, and the related applications in the civil field have also developed rapidly after the first year of the new calendar.

Hao Yun didn't know what the breakthrough Wu fan was talking about.

In any case, it didn't sound like a joke to him.

With this idea in mind, Hao Yun followed Wu fan's steps and came to a laboratory in the depth of the Research Institute.

The layout of the laboratory is very simple. There is a half person high screen in the middle of the spacious room. On the table in front of the screen are two sunglasses.

"... strictly speaking, what we have accomplished is not augmented reality technology, but on the basis of augmented reality technology, we have made some improvements."

"Improvement?"

"That's right."

Walking to the screen, Wu fan picked up two glasses from the table and handed one to Hao Yun.

"Remember what I told you before? In the research of brain computer interface, the main problem we are facing is how to accurately identify brain wave signals and translate them into computer language that can be understood by machines

Hao Yun nodded his head, looked at his glasses strangely and said.

"It does seem to have been said... But what does this have to do with AR technology?"

"That's to say that we've made a breakthrough recently!" With a smile on his face, Wu fan continued in an excited tone, "after a year's efforts, the acquisition and modulation and demodulation technology of brain wave signals has been completed by our researchers!"

Before Hao Yun asked what it was, Wu fan took the initiative to introduce it to him.

The acquisition and modulation and demodulation of the EEG signal is the collection of the signals emitted from the human brain, and after processing, the modulation and demodulation is made into computer language.

As for why this technology is applied to AR devices, we have to start from the technical route selection of cloud dream technology in the research of brain computer interface technology.

For the sake of commercialization and security, Yunmeng Technology Research Institute mainly focuses on the research of "non-invasive" brain computer interface.

To put it simply, it's an extra brain patch, not an intracerebral intubation.

The main advantages of this technology route are user experience and security, but the existing problems are also obvious.

The first one is signal acquisition.

Compared with collecting signals directly from the cerebral cortex and observing brain activity indirectly through the changes of brain waves, the signal strength and accuracy are obviously inferior to the invasive brain interface.

Therefore, for Brain Computer Interface Research Institute, how to accurately identify and process brain wave signals has become a key problem.

But now, this technical problem has been solved.

Brain computer interface research institute not only successfully solved the problem of collecting and modulating and demodulating brain waves, but also applied it to AR technology, and realized the operation of "ar" equipment through the idea.

Compared with the AR device which used to complete human-computer interaction through gestures and body movements, this advanced operation mode not only looks less stupid, but also much safer and more convenient.

Under the guidance of Wu fan, Hao Yun, who wears ar glasses, soon mastered the essentials of using this device. Through the scene switching function, he instantly turned the laboratory into a castle, and then turned the castle into a golden paddy field.

Most of these materials came from the "Warcraft" crew next door, but it was because of this that Hao Yun's shock and joy became more intense.

If you use this device to play games, it's no more powerful than computers and mobile phones?

Especially now, there is no need to operate the equipment by hand gestures. Things like hitting the wall because of too much devotion or being looked at with strange eyes by others have become the past.

Looking at the happy expression on Hao Yun's face, Wu fan, who didn't know what the boss was thinking, continued with a smile.

"Next, the focus of our research is to find a way to interfere with brain activities through electrical signals! Now we can only achieve single signal acquisition, still need to use the display and speaker to feed back the picture to the user. In the next stage, we will try to completely abandon these two devices and directly transmit images and sound to the user's mind! "

"At present, our idea is to achieve a virtual reality like effect in the form of dreams with the help of deep sleep. Although some progress has been made in animals, there is another problem involved, that is, we can't ensure that users can go to sleep immediately after startup. "

"Just imagine, if we need to fall asleep every time we connect a virtual reality device, I'm afraid we have to spend more than ten minutes or even more than half an hour to turn on the machine."

"What's more, it's not easy to fall asleep with a burden."

Wu fan, who was standing on one side, was more and more excited, and his hands were constantly gesticulating. However, Hao Yun's attention was not on the content he was talking about, but was completely attracted by the picture he saw in his pupils.

This is a blockhouse, OK!

Whether it is used for playing games or daily use, I believe that as long as the price is appropriate, the vast majority of consumers will not refuse such an electronic product that can be easily controlled with ideas.

Interrupted Wu fan's talk, Hao Yun said immediately.

"How much does it cost to make one of these? Is it expensive? "

In the face of this sudden problem, Wu fan Leng next, after thinking about a face embarrassed to say.

"Well, I don't know that."

"But boss, if you want to put this thing on the shelf, I have to remind you that our patent reserve in AR technology is close to zero... Including the glasses in your hand, they are all improved versions through rice ar glasses."

"And because it takes a lot of computing power to process EEG signals, we have to equip the glasses with a Bluetooth connected host. It's like the glasses in your hand. Although they seem very convenient to use, they can't be used out of this room. "

Taking off AR's eyes and holding them in his hand, Hao Yun frowned and said.

"Let's not worry about patents. As long as there is a market, there should be a way to solve this problem... As for the glasses you said, it's really a problem that they need to be equipped with a host, but can't it be solved through cloud technology?"

Wu fan scratched the back of his head and said.

"Do you intend to provide cloud computing services for users? Theoretically, it can, but... I'm afraid the cost is not small. "

"As long as it can be realized technically, I think it's valuable to have a try," he said after returning the glasses to Wu fan. Hao Yun looked at him with a smile and continued, "I'll just worry about it. I'll consult professionals. You just need to be responsible for optimizing this device as I said!"
