Method, device and equipment for man-machine interaction based on brain wave signals

The invention discloses a method, device and equipment for man-machine interaction based on brain wave signals. The method comprises the steps that original brain wave signals are acquired through brain wave acquisition equipment and preprocessed; based on the currently started man-machine interaction mode, according to at least one state index required in each man-machine interaction mode, performing feature extraction on the preprocessed brain wave signal; determining the state value of each current state index according to the brain wave feature information corresponding to each state index obtained after feature extraction; and according to the state value of each state index, when it is determined that a control starting condition in any man-machine interaction mode is satisfied, executing a control function corresponding to the man-machine interaction mode. The real mental state of the user is monitored based on the brain wave signal, the recognized real intention of the user is converted into the corre
