Beijing, May 5 (Reporter Song Yusheng) "With the advancement of science and technology, brain-computer interface will become an indispensable technology for human beings. ”
After the parallel forum of the 5 Zhongguancun Forum "Brain-Computer Interface Innovation and Development" held on May 29, Gao Xiaorong, a tenured professor at Tsinghua University, described the importance of brain-computer interfaces in an interview.

"Humans need to interact with machines, for example, to drive a car, we have to have a steering wheel; To use a computer, we must have a mouse, a keyboard. With the advancement of artificial intelligence technology, these devices are not enough to meet the needs of human-computer interaction, and the future information transmission speed will be much faster than today. Therefore, new technologies must be needed, and brain-computer interfaces are such a more suitable technology. Gao Xiaorong explained.
However, limited to the current level of technology, brain-computer interface application scenarios are mainly clinical trials. And it has not been widely promoted in the field of medical clinics.
Zhao Jizong, academician of the Chinese Academy of Sciences and executive committee member of the World Neurosurgical Union (WFNS), believes that after this technology matures, it should first be applied to the field of clinical medicine to solve the problems of patients.

Zhao Jizong pointed out that at present, this technology is mainly used in the clinical trials of such types of patients, that is, for patients with consciousness disorders, brain-computer interface technology can determine whether the patient is awake; For patients with paralysis caused by spinal cord injury, brain-computer interface technology is applied to implant an electrical stimulator in the injury segment, which can promote the patient's walking by the signal sent by the electrical stimulator.
In Zhao Jizong's view, even in clinical trials, there are still problems in brain-computer interface technology such as materials, industrialization, and ethical compliance to be solved.
"For example, whether the materials of invasive brain-computer interface devices can be in the human body for a long time without side effects on the nervous system is an urgent problem to be solved upstream of brain-computer interfaces; At present, the research on brain-computer interface in various countries is still a case, and the existing industrialized equipment is still a certain distance from the real technical application. He said.
As for the ethical compliance of brain-computer interface technology, Zhao Jizong pointed out that once this technology is widely promoted and applied in the future, it will inevitably collect a large number of human brain signals, and this belongs to privacy, and relevant guidelines also need to be laid out in advance.
"There is a good side to any technology, and there is a dangerous side to it." Gao Xiaorong emphasized that in addition to clinical, human beings should also focus on preventing the risk of abuse of brain-computer interface-related technologies.
"One possible scenario in the future is that people who have access to brain-computer interface technology in the future may be better able to control machines than people who do not. This will widen the gap between people. He told reporters that human beings should not affect social equity due to the use of brain-computer interface technology, so the application of related technologies must be regulated. (End)
