Abstract: This invention relates to a method to control at least one actuator to carry out at least one task comprising repetitive sequences of operations, shorter than 1000 milliseconds by acquiring of endogenously generated electrical potentials within gamma frequency range generated by the brain and/or by the muscles of the body, head, or eyes of a human user, by acquiring electrical signals with sampling rate of at least 250 samples/s, by extracting the features of the signals related to high-frequency gamma waves between 30-200 Hz, by classifying, mapping and converting the signals into actions in real time, and by sending feedback and neurofeedback to a human user to enable him to control the interface.
