Chapter 439 (1/2)

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.
