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

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

First of all, the structure of Chinese characters is very complex. Not only is there a lot of strokes, but it is also very difficult to write, and the diversity of homophones, similar characters, synonyms, rare characters, and traditional Chinese characters also makes the test difficult.

The sentences made up of these Chinese characters are even more complex.

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

One of the simplest methods is to use contextual association recognition technology similar to intelligent speech system, or intelligent input method, etc., to associate and judge the accurate vocabulary in the sentence through a whole sentence.

This technology largely solves the problems of multi-sound, multi-meaning, and proximity of words and Chinese characters, which improves the efficiency of input recognition.

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

However, the brain's thoughts and thoughts change rapidly, and with this associative recognition technology, some of them cannot keep up with the speed of the brain's thinking, and there may be errors.

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

When Cai Tao looked at the original text of this article and read it, each word was transmitted to the brain through the eyes, and a specific EEG signal was formed, which is the memory signal of the text in our brain and recorded by our brain.

As for the brain-computer sensing system, it captures this EEG signal and recognizes it, and restores it into the text itself, which 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 these relay information, which is also a topic that the scientific research team needs to study, and it is also the main difficulty.

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

Just like when Cai Tao reads the preface of this familiar Lanting collection, he can't help but think back to his middle school life, as well as 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 reads this kind of article that he is familiar with, he will inadvertently speed up. This is true for reading, and the same is true for the brain. How to capture these EEG signals under this kind of fast thinking is also a technical problem in front of the R&D team.

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

Sure enough, the results of this test were far less good than the previous one. In the "Lanting Collection Preface" produced by Cai Tao's EEG signals captured and recognized by brain-computer sensing equipment, there were many errors.

Typos, typos, misstatements, and even other things mixed in.

In the face of such data, the big guy can't help but be a little frustrated. Sure enough, it still doesn't work.

Of course, Wu Hao also felt this atmosphere, and then he smiled and clapped his hands and encouraged everyone: "Don't be discouraged, in my opinion, this test result has been very successful." Without the assistance of intelligent association recognition technology, it has been able to capture and recognize articles, and the accuracy rate has reached 87%, which is already very remarkable.

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

So, don't be too discouraged, let's keep up the good work. I believe that with the efforts of all of us, this technology will definitely be carried forward in our hands. ”

"Mr. Wu is right, let's not be too decadent, this technology has been developed from scratch to the point where it is very powerful. I'm proud of our whole team and of each and every one of us. We continue to work hard and I am sure that these problems will be solved soon. Ding Zifei also opened his mouth to boost the morale of everyone.

Sure enough, he started his own business, and in just a few words, he was able to cheer everyone up. Of course, what Wu Hao said earlier also played a vital role. Otherwise, it would be impossible for these people's emotions to be appeased in such a short period of time.

"Alright, let's move on to the next test." Ding Zifei opened his mouth to order, and then introduced himself to Wu Hao.

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

Wu Hao knew that at the artificial intelligence conference before, there were related research teams that did a similar test link, typing through brain consciousness.

At that time, the test was very eye-catching and attracted the attention of the whole society. Some experts even say that the brain-computer sensing device will soon be put into commercial use, bringing good news to patients with high paraplegia and ALS who are plagued by diseases, and even to vegetative people.

But after all these years, the technology has not been commercially available, as the expert said.

Looking back at the conscious typing technology displayed at that time from the current perspective, it is still very rudimentary, and the fourth degree is very slow, basically through pinyin, letter by letter, and the efficiency is very low.

"The test begins, Cai Tao, write down the "Lanting Collection Preface" you read in the last test."

"Okay!"

Immediately, in the blank Word document, Cai Tao quickly began to type. The speed is very fast, and the entire Lanting set preface, a total of 400 characters, was written down silently in less than thirty seconds. And the speed is very fast, I only see the input box flashing constantly, and the text and vocabulary input are not clear at all.

"27 seconds, which is equivalent to 14.814 words per second, an increase of 0.6 words from the last test, a good result!" Ding Zifei looked at the data on the screen and said with a smile,

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 put on the market for commercial use!" Wu Hao applauded and praised Ding Zifei.
