Detecting method for multi-modal brain switch based on SSVEP and P300

The invention discloses a detecting method for a multi-modal brain switch based on SSVEP and P300. The method comprises the following steps: generating a scalp electroencephalogram signal by a user according to a working interface command in a display device; collecting the scalp electroencephalogram signal by an electrode cap, and transferring the signal by an I/O interface module of a computer to a signal processing module in the computer after the signal is converted by a digital-to-analogue conversion module and is amplified by a signal amplifier; copying the scalp electroencephalogram signal into two copies, and respectively performing P300 electric potential detection and SSVEP detection; classifying the control state and the idle state by combining the respective detection output of the P300 electric potential and the SSVEP, and determining goals. For the detecting method, the problem that pages with complex contents cannot be browsed for a browser based on the non-mouse control can be solved, the control speed is greatly improved, and the precision is greatly improved.
