Chapter 25-Annexure 678
Chapter 6: Hong Bo, Associate Professor of the Institute of Nervous Engineering at Tsinghua University, commented on China's brain control technology.
Brain-computer interface technology had been a hot topic in the field of neural engineering in the past decade. The basic principle was to record and analyze the brain's signals (brainwave signals, optical signals, MRI signals, etc.), infer the brain's thinking activities, and translate them into corresponding commands to control computers or other electronic devices. This technology was originally intended to help disabled people who had lost their ability to move, allowing their brains to directly control prosthetics, wheelchairs, household appliances, computers, and so on.
In fact, China, the United States, Austria, and other countries were currently leading the world in this field. Japan had only begun to study this technology in recent years. It mainly used optical imaging methods, which were slow and had low accuracy. Tsinghua University had been researching the " brain-computer interface " technology since 1999. Currently, it was at the forefront of the world in terms of communication speed and accuracy. It could make phone calls, remotely control television, command robots to play football, and so on. The technology was mature and stable, and it was closer to being practical. In the last two international brain-computer interface data competitions, China won many first places. At present, China already had a core technology that had obtained a US patent, and many other technologies had obtained domestic patents. In recent years, Tsinghua University and relevant research institutions in Hong Kong have cooperated to conduct experiments on the use of brain-computer interface for patients with paralysis. It is expected that in the next three to five years, disabled people are expected to truly benefit from this technology in their daily lives.
The so-called "things follow the heart" was just an image. What really made the "object" move was not the "heart" but the electronic device that was commanded by the computer. This command was interpreted from the brain's thinking activity. At present, computers could only distinguish very few simple thinking activities, such as imagining hand and foot movements, performing mathematical operations, humming songs, and so on. On the one hand, the human brain's thinking was very complicated, and the rules of fine thinking had not been studied clearly. On the other hand, with the current level of technology, the brain activity that could be detected was very weak, and it was drowned in all kinds of noise. It was very difficult to analyze and process. (Interviewer: Our reporter Yang Xuan)

(Editor's note: From the comments of the authoritative expert Professor Hong Bo, China's brain control technology has already developed to the application stage.) This showed that the human brain mind control technology, which was based on the acquisition, interpretation, transmission, and control of information in the brain, did exist in China. It proved the reality of the brain thinking and communication technology involved in this case in China.）
Chapter 7: Tsinghua University's brain-computer interface system can control computers with thoughts
June 15, 2006? 07:22 Beijing News
(Reporter Wu Di) Yesterday, in a laboratory of the Department of Biological Engineering at Tsinghua University Medical College, a special football match was going on. The two intelligent robot dogs on the field were the "striker" and the "goalkeeper". The red robot dog "goalkeeper" had a football placed behind it. The gray robot dog "striker" on the other side of the field had to cross the obstacle (teacup) in front of it, charge to the end of the field, and successfully avoid the "goalkeeper" to kick a ball.
Playing football with imagination
This was the venue where Tsinghua University was displaying their world-leading brain-computer interface system. One of the project leaders, Hong Bo, a doctor from the Department of Bioengineering at Tsinghua University Medical School, explained on the spot, Before a person considered whether to go left or right, they would first form a thinking activity in the corresponding nerve center. It was these thinking activities that controlled every specific action of a person. A person's thought activity would form corresponding brainwaves. As long as these brainwaves were collected, it was equivalent to collecting what a person's thought activity was. Therefore, the key to this competition was to extract the brainwave signals of the two students and directly turn them into the control commands of the intelligent robot dog.
Use your eyes to dial the phone
Similar to the principle of controlling the robot dog to play football, Tsinghua University demonstrated the ability to "dial" the phone with their eyes.
One of the students had lost the ability to move his limbs due to an accident and could only use his mind to call his relatives and friends. In front of this "disabled" student was a phone panel with the numbers "1-9" and a B(backspace) and C(call) keyboard. He stared at each number for 3-5 seconds. After 1 minute and 18 seconds, the call was successfully dialed.
This technology recorded brain waves in real time, interpreted people's simple thoughts to a certain extent, and translated them into control commands to realize the control of computers, household appliances, robots, and other equipment.
Hong Bo introduced that this cutting-edge combination technology of artificial intelligence and biological intelligence was initially used to help disabled people who had lost their ability to move but had normal brain function. Through such a system, they could use their own thoughts to directly control wheelchairs, prosthetics, and even use computers to surf the Internet. At present, the technology had already applied for a national patent.
On-the-spot mental attack illusory contest
Different from the regular robot dog soccer game, the command and control of this soccer game was not a computer program, but two Tsinghua University students, a man and a woman. The man and the woman each wore an electric cap on their heads and faced the brainwave display screen that recorded their thoughts.
The game began. The " goalkeeper " on the field cleverly moved to the right and successfully crossed the obstacle to advance forward. Seeing that the " striker " was only charging at the target behind him, the " goalkeeper " hurriedly moved to the left to intercept.
The forward, who was about to intercept the goalkeeper, suddenly changed his tactics and moved to the right quickly. The goalkeeper, who could not react in time, immediately panicked and quickly moved to the left. Seeing that the goalkeeper had an empty spot, the striker immediately pounced on the ball and kicked it in.
"Wow!" The audience burst into applause. The entire match only took five minutes.

"Mind Control of Objects"-China's Brain Wave Interpretation Technology Is at the Leading Level in the World
CCTV International, cctv.com. July 16, 2007 18:57 Source: CCTV.com
CCTV.com news (News broadcast on July 16):
Using " thoughts " to control the switch of electrical appliances and the movement of objects, this scene in science fiction movies has now become a reality by Chinese scientists through " brain-computer interface technology."
The test he was doing now was to use his " thoughts " to make a call. The tester only needed to stare at a number flashing at a different frequency on the keyboard, and the computer would automatically dial the number.
Gao Xiaorong, Professor of the Department of Biomedicine Engineering, Tsinghua University School of Medicine: When he looks at a flashing number, there will be different frequencies in his brainwaves that our computer can recognize.
This moving robot was even more interesting. If you wanted it to turn left, you would have to move your left hand. If you wanted it to turn right, you would have to move your right hand.
Hong Bo, associate professor of the Department of Biomedicine Engineering at Tsinghua University School of Medicine: When we imagine the movement of our left hand, right hand, or foot, there will be different patterns in our brainwaves. By detecting these different patterns, we can translate this imagination into commands to control the machine.
Scientific research had found that when the human brain thought, the brain nerves would produce tiny electric waves that were one-millionth the size of an A-5 battery. By analyzing these electric waves, one could determine the brain's intentions. This was the brain-computer interface technology, which had a wide range of application prospects in improving the quality of life of disabled people. In the most recent international brainwave data interpretation competition, the Chinese research team won first place in three of the seven tests.
Academician Yu Mengsun of the Chinese Academy of Engineering, leader of the Tenth Five-Year Science and Technology Research and Inspection Team: The most important part of the brain-computer interface is the interpretation of brainwaves. We are already in the international leading position in this area.
At present, China's "brain-computer interface" technology has been included in the "Eleventh Five-Year" National Science and Technology Support Plan and other key projects.
