China brain-computer interface patent application.

Since the concept of brain computer technology came into being in the 1970s, the United States first realized the virtual classification of EEG in 1988. The application progress of brain-computer technology is a bit ahead of schedule. For example, in the medical field, computer technology in the brain is used to help paralyzed patients control their limbs, and to help electric drivers control prosthetic limbs or control seizures to control their limbs.

Brain computer technology realizes the functional control of the brain by establishing an information channel between the brain and external devices, and then using bioelectrical signals. This technology is to collect signals, process them, translate them into computer language, and finally get the effect through feedback. According to the different ways of brain wave acquisition, brain computer technology can be divided into invasive technology and non-invasive technology. An invasive method is to inject brain activity detection equipment into the brain to obtain brainwave biological signals. Non-invasive brain-computer technology, that is, setting a brain signal catcher in vitro to obtain brainwave biological signals.

Brain computer technology is expected to become a new technology sweeping the world after artificial intelligence technology, triggering another global technological revolution. BCI will be widely used in medical treatment, virtual reality, educational technology, smart home and other fields. According to news reports, the market of brain-computer interface is quite huge. From the commercial field where brain-computer technology was first applied, brain-computer interface technology is likely to become a crucial technology to promote the future social development. The competition between China and the United States in the research and development of brain computer technology can be said to be very fierce. In the patent application of brain computer technology, both countries are far ahead of other countries in the world. The main research direction of brain-computer technology in various countries is electronic digital data processing.

The development of brain computer technology can greatly benefit mankind. For example, this technology can help some patients with functional disorders to express their ideas better and provide creativity. It can help people recover their lost consciousness: people who lose their perceptual ability can help them gain their perceptual ability in the future, besides controlling some equipment to think, which is the five senses of people. This can also realize the transformation of external perception. For example, human beings can realize the perception of ultrasonic waves and realize the perception of ultrasonic waves from the perspective of sensing magnetic fields. And in the field of teaching, this technology can help teachers quickly understand the classroom environment, change the current situation of education, and then help students improve the efficiency of classroom acceptance.
