Abstract：
 The invention belongs to neuro engineering in biomedical engineering. The method includes following steps: placing brain electrode on scalp of testee; using blinker light in different frequency to stimulate testee; making scalp of testee generate brain wave in same frequency and harmonic component; through amplification, brain wave is converted to digital signal, which is sent to computer; computer analyzes and detects main frequency component; based on coincidence relation list between frequency of brain wave and mouse action or control command, the method sends mouse action or control command corresponding to flash concentrated by testee so as to realize interactive interface between human brain-computer. The invention can help handicapped person to use computer, or normal person in situation of not convenient to use hand to operate computer, for example astronaut in airship or space capsule.
