摘要：
FIELD: medicine.SUBSTANCE: invention relates to medical equipment, namely to a method of controlling devices by recording and processing electroencephalogram (EEG) signals. EEG signal recording means with the help of associated sensors are used to record (212) electric brain activity with the possibility of separating alpha rhythm and beta rhythm of the user's brain. Analog-to-digital converter of recording means converts (212) obtained signal from analog data format to digital with sampling rate (fd), where fd is greater than or equal to the upper boundary frequency for the respective frequency band multiplied by two. Frequency range for alpha rhythm and / or for beta-rhythm of the user's brain is set by setting the lower (a) and upper (b) boundaries of the frequency range for each of the rhythms. Registered user's brain activity of the user is transmitted in the analogue or digital data format to the processing means. Processing unit of the processing means is used to decompose (222) the EEG signal into the spectrum for given spectral components in the frequency range from a to b, consisting of n discrete frequency components (fn), where fn is amplitude of n-th spectral component, with selection of rhythm of user's brain by removal of all frequencies preset outside preset range. Frequency extraction module calculates (232) the spectral power value by summation of discrete frequency components in the case of the digitized signal or by integration of spectral components f(x) of the signal at frequency x in the case of an analogue signal and the calculated value is transmitted to the solver. One of preset types of generated control commands is selected, where type of generated command is trigger or proportional control command. Solver is used to compare (242) the calculated spectral power value with a given threshold value and generate (252) a control command depending on the spectral power value. At the selected trigger command at value of the calculated spectral po
