Compared with the previous English letters, this "Lanting Collection Preface" is more difficult, and it has more stringent requirements for the EEG signal capture and recognition capabilities in the brain-computer induction system.

The first is the transition from a single English letter to Chinese characters, especially the complexity of our Chinese characters, which is a very severe test for the accuracy of the brain-computer sensor system to capture and recognize.

First of all, the structure of Chinese characters is very complicated. Not only is there a lot of gestures, but it is also very difficult to write, and the diversity of Chinese characters with homophones, similar characters, synonyms, rare characters, and traditional characters also increases the difficulty of the test.

The sentences composed of these Chinese characters are more complicated.

How to make the brain-computer induction system accurately recognize the words imagined in one's brain requires relevant technical support.

The simplest method is similar to the intelligent voice system, or the intelligent input method, etc., using contextual association recognition technology, through a whole sentence to associate and judge the accurate vocabulary text in the sentence.

This technology largely solves the problems of polyphonic, multi-meaning, and similar forms of vocabulary and Chinese characters, which improves the efficiency of input recognition.

If you just want to do an input method, then this kind of contextual association recognition technology is no problem in the field of brain-computer induction technology.

But the mind's mind is changing rapidly. Using this association recognition technology, some of them cannot keep up with the brain's thinking speed, and errors may occur.

Therefore, in the development of their project, Wu Hao asked the research team to avoid using this contextual association recognition technology as much as possible. It can only exist as the final optimization tool, not as the main technical body of this system.

When Cai Tao reads the original text of this article, every word is transmitted to the brain through the eyes, and forms a specific EEG signal, which is the memory signal of this word in our brain, and is Recorded by the brain.

The brain-computer sensing system captures this brain electrical signal and recognizes it and restores it to the text itself. This is the main content of this test.

To put it bluntly, in this test, the brain only plays a relay transmission function. Don't underestimate this function. How to ensure the accuracy and speed of the transfer information is also a topic that the research team needs to study, and it is also a major difficulty.

The second difficulty is interference, constant interference, especially when reading familiar articles, it is easy to be disturbed by other incidental memories.

Just like when Cai Tao was reading this familiar preface to Lanting, he couldn't help but think of his middle school life and some memory information closely related to this text. How to eliminate the interference of these memory information and accurately capture and identify the content of this text is also a very difficult problem.

The third problem is that when Cai Tao is reading this familiar article, he will inadvertently speed up. Reading is the same, so is brain thinking. How to capture these EEG signals under this fast thinking is also a technical problem facing the R&D team.

Of course, there are still many difficulties, so I won't list them all here.

Sure enough, the result of this test is far better than the previous test. In the "Preface to the Lanting Collection" produced by Cai Tao's EEG signals captured and recognized by the brain-computer sensing device, many errors appeared.

Wrong words, wrong words, wrong sentences, and even some other content.

Faced with such data, the big guys can't help but feel a little frustrated. Sure enough, it still doesn't work.

Of course, Wu Hao felt this atmosphere. He immediately smiled and clapped his hands to encourage everyone: "Don’t be discouraged. In my opinion, this test result has been very successful. Without the help of intelligent association recognition technology. I have been able to capture and identify articles, and the accuracy rate has reached 87%, which is already very remarkable.

It can be said that my test results, even if placed in the world, are definitely far ahead.

So, everyone, don't be too discouraged, let's keep working hard. I believe that with the hard work of all of us, this technology will be carried forward in our hands. "

"Mr. Wu is right, let's not be too decayed. This technology has grown out of nothing, and it has reached this point. I am proud of our entire team, and I am proud of each of us. We continue to cheer, I believe these problems will be resolved soon." Ding Zifei also opened his mouth to encourage everyone.

Sure enough, I started my own business. Just a few words can cheer everyone up. Of course, what Wu Hao said earlier also played a vital role. Otherwise, the emotions of these people cannot be soothed in such a short time.

"Okay, let's proceed to the next test content." Ding Zifei opened his mouth and ordered, and then introduced to Wu Hao.

"The content of this test is the normal text input method. The intelligent association input method is used for input testing. This is also a content we often test. The accuracy rate can reach more than 99%, and the input speed is ours The keyboard input speed is two to five times faster. It can be said to be the gospel of writers and the nemesis of tentacle monsters."

This test Wu Hao knew that at the artificial intelligence conference, a related research team had done a similar test session, typing through brain consciousness.

At that time, the test was very eye-catching and attracted the attention of the whole society. Some experts even said that brain-computer sensing devices will soon be put into commercial use, bringing the gospel to high-level paraplegia and frostbite patients suffering from disease, and even to vegetative people.

But after so many years, this technology has not been put into commercial use as the expert said. UU Reading www.uukanshu.com

Looking back at the conscious typing technique displayed at that time from the current point of view, it is still very basic, and the four degrees is very slow, basically using pinyin, one letter by letter, which is very inefficient.

"The test begins, Cai Tao, silently write down the Preface to the Collection of Orchid Pavilion you read in the last test content."

"Ok!"

Immediately in the blank Word document, Cai Tao quickly began to input. Very fast, the entire Lanting Collection Preface, with a total of 400 characters, was silently written in less than thirty seconds. And the speed is very fast, only to see the input box is constantly flashing, the text vocabulary input is not clearly visible at all.

"27 seconds, equivalent to words per second, 0.6 words higher than the previous test, good results!" Ding Zifei smiled as he looked at the data on the screen.

Bang bang bang...

Wu Hao took the lead in applauding, and soon the whole laboratory was filled with applause.

"Yes, I think this technology can be commercialized in the market!" Wu Hao applauded Ding Zifei while applauding.
