Chinese scientists have introduced the brain-computer interface (BCI), which establishes communication between the brain and the
It is noted that the presented electromagnetic metasurface with a brain-computer interface can not only translate signals from the operator's brain into commands, but also carry out wireless "mental communication" between two operators.
A display is placed in front of the person to display commands. The operator simply looks at the desired command, and the system understands this and works.
Scientists have already demonstrated the operation of the prototype.They carried out the wireless transmission of text from one operator to another. It has been shown that when a target letter is decoded from an EEG signal, an ASCII-based encoding sequence is performed on the metasurface. The second operator system receives the signal and presents the result on the display. The average input time for each character was about 5 seconds.
