摘要
A brain-machine interface apparatus and a method of the same are provided. To elaborate the brain-machine interface apparatus may include a display where a plurality of light-emitting points (or lines) flickering with their individual set frequencies are arranged a flickering controller that divides the plurality of the light-emitting points (or lines) into a plurality of groups, and sets the set frequencies for the groups; an EEG measurement unit that detects EEG signals of a user who watches the display without gaze-shift; a frequency detector that detects one or more (their harmonic or combination) frequency components from the measured EEG signals; a shape analysis unit that decodes an originally intended shape according to the user's imagination based on the one or more detected frequency components and the set frequencies; and a result output unit that outputs information of the embodied originally intended shape.
