The brain-computer interface, sometimes referred to as a "brain port" or "brain-computer fusion sense", is a direct connection path established between the human or animal brain or a culture of brain cells and an external device. In the case of a one-way brain-computer interface, the computer either accepts commands from the brain or sends signals to the brain, such as video reconstruction, but cannot send and receive signals simultaneously. While a bi-directional brain-computer interface allows bi-directional information exchange between the brain and external devices. The brain-computer interface is a direct communication and control channel established between the human brain and a computer or other electronic equipment, through which a human can express ideas or manipulate the equipment directly through the brain without requiring language or actions, which can effectively enhance the ability of a severely physically disabled patient to communicate with the outside or control the external environment to improve the quality of life of the patient. The brain-computer interface technology is a cross technology relating to multiple disciplines such as neuroscience, signal detection, signal processing, pattern recognition and the like.
The noninvasive brain-computer interface is to wear an electroencephalograph (EEG) cap containing a plurality of electrodes on the head instead of implanting a microchip for operation on the brain, collect and record weak bioelectric signals generated by the head, and then amplify the signals.
