FIELD: medicine.SUBSTANCE: EEG frequency response is pre-determined by a period analysis in a highly-watchful live operator being involved in active visual-motor activities and in actual activities. Theta-, alpha- and gamma-wave count per second is measured. The derived values are compared. If the theta-, alpha- and gamma-wave count per second is stated to fall outside the values specific for high watchfulness, an EEG analyser converts a sequence of the values into a sensory signal and feeds a biofeedback-like warning signal automatically to state the control circuit logoff by the live operator.EFFECT: method improves the accuracy of the control measurements enabling feeding the sensory signal in due time that is ensured by pre-determining a combination of highly-watchful EEG theta-, alpha- and gamma-wave frequencies.1 dwg, 2 ex |
