SSVEP-based brain-computer interaction method and device, electronic device and storage medium

The invention relates to SSVEP-based brain-computer interaction, and an SSVEP-based brain-computer interaction method comprises the steps: obtaining a brain-computer interaction instruction, obtaining a plurality of visual interaction graphs based on the brain-computer interaction instruction, each visual interaction graph corresponding to interaction information, each visual interaction graph comprising a stimulation graph and a focus graph, converting the stimulation pattern and the focus pattern at different frequencies; obtaining electroencephalogram data generated by the collected person based on the target visual interaction graph, recognizing the electroencephalogram data, obtaining a recognition result, and the recognition result comprises the target visual interaction graph watched by the collected person; and obtaining corresponding interaction information based on the identification result. Through the method and the device, the problem that the brain-computer interaction effect is relatively poor
