Brain Computer Interface

Brain-Computer Interface (BCI) is a technology that enables direct communication between the brain and external devices such as computers or machines, without the need for muscle or peripheral nerve activity. BCI works by detecting and interpreting brain signals, converting them into commands to control external devices or providing feedback information to the user, thus establishing a bidirectional communication pathway between the brain and the device. This technology can be implemented primarily through non-invasive methods like Electroencephalography (EEG) or invasive electrode implants, and it holds significant medical application value.
