Summary: | The invention relates to a brain-computer interaction device, system and method, the brain-computer interaction device comprises a display module, an acquisition module and a processing module, the display module comprises a plurality of pixel points of which the switching frequency can be independently adjusted, and all pixel points in a preset area flicker according to a preset flicker frequency to form a to-be-identified interaction image; all pixel points outside the preset area are refreshed according to the refresh frequency of the display interface; the acquisition module is used for acquiring an electroencephalogram signal generated by an acquired person based on the to-be-identified interactive image and transmitting the electroencephalogram signal to the processing module; the processing module is used for receiving the electroencephalogram signals and recognizing the electroencephalogram signals to obtain a recognition result, and the recognition result comprises the target interaction image watche |
