According to the enterprise research app, the Agricultural Bank recently announced a patent for “a banking system interaction method and device based on a hybrid brain-computer interface”. The patent abstract for enterprise investigation shows that the application collects eye electrical signals in real time. When the eye electrical characteristic value of the collected eye electrical signal is less than the eye electrical characteristic threshold, this indicates that the EEG signal has not been contaminated by the eye electrical signal. The collected EEG signal is relatively accurate data, so the noise reduction of the eye electrical signal is further reduced, and then the spectral value of the denoyed EEG signal is monitored to obtain the power spectrum characteristic value of the denoyed EEG signal. If the power spectral characteristic value of the EEG signal after denoising is higher than the EEG characteristic threshold value, this indicates that the EEG signal is effective. Then it goes further to the EEG signal Stimulus sources are classified, and the operating banking system is controlled based on the classification results of EEG signals. The application improved the robustness and control accuracy of the banking system.
