FIELD: medicine. ^ SUBSTANCE: system comprises a biological signal measurement unit, an electroencephalogram interface unit for discriminating a user's request and identifying a function which is linked to the user's request, an analysis unit for measuring and the analysing a physical value, an event-related potential waveform storage unit, a user's characteristic extraction unit and a setup unit. A procedure consists in setting up a discrimination method in the electroencephalogram interface unit and provides measuring a visual and/or acoustical stimulation related physical value to be accepted as a characteristic value of stimulation. It is followed with finding variations of the characteristic value of stimulation which has an effect on the event-related potential. The event-related potential waveform is saved, and a user's characteristic value is extracted while being based on the saved event-related potential waveform. A random-access memory stores a computer program and activates a computer to follow the steps of said setup procedure. ^ EFFECT: simplified calibration, more precise identification of electroencephalogram and high-manipulation interface. ^ 16 cl, 15 dwg |
