Since the concept of brain-computer technology arose in the 1970s, the first virtual staging of an EEG was realized in the United States in 1988. The progress of the application of brain-computer technology is a little ahead of schedule. For example, in the medical field, computer technology in the brain is used to help paralyzed patients control their limbs, to help trolley hands control prosthetic limbs or to control seizures to control limbs.
Computer-in-the-brain technology enables functional control of the brain by creating an information pathway between the brain and an external device, and then utilizing bioelectrical signals. This technology is based on the collection of signals and their processing, then translated into computer language and finally feedback to get the effect. According to the different ways of acquiring brain waves, brain computer technology can be categorized into invasive and non-invasive technology pathways. An invasive approach is obtaining brainwave biosignals by injecting brain activity detection devices into the brain. A noninvasive brain-machine technology, in which a brain signal trap is set up outside the body to obtain brainwave biosignals.
Brain computer technology is expected to become an emerging technology sweeping the world after artificial intelligence technology, and trigger another global technological revolution.BCI will be widely used in medical treatment, virtual reality, education technology, smart home and other fields. News reports say that the brain-computer interface market is quite large. Judging from the commercial areas where brain-computer technology was initially applied, brain-computer interface technology is likely to become a crucial technology that will drive the development of society in the future. The competition between China and the United States in the development of brain computer technology can be fierce, with both countries far ahead of the rest of the world in terms of patent applications for brain computer technology. The main research and development direction of brain computer technology in each country is data processing of electronic numbers.
The development of brain computer technology can greatly benefit mankind. For example, this technology can help some patients suffering from dysfunction to better express their ideas and provide creativity. It can help people regain lost perception: In addition to thinking by controlling certain devices, those who have lost the ability to perceive can be helped in the future to gain the ability to perceive, that is, the five human senses. This could also enable the transformation of external perceptions. For example, it is possible for humans to realize the perception of ultrasonic waves, by perceiving magnetic fields from the point of view. And in the field of teaching, this technology can help teachers quickly understand the classroom environment, change the status quo of education, and then help students improve the efficiency of classroom acceptance.
