Embodiment Construction
[0022] The mixed-paradigm brain-computer interface that combines steady-state visual evoked potential (SSVEP) with the P300 component of event-related potential can simultaneously induce these two EEG components, expand the number of subjects, and have broad application prospects and technical advantages. The present invention designs a new strategy induced by SSVEP and P300 in parallel. For the first time, the mixed paradigm instruction set is expanded to 108, and finally the two kinds of feature information are identified and fused. The relevant research ideas of this coding strategy can be large instruction set, It provides a reference for the design and promotion of the mixed paradigm brain-computer interface system with high information transmission rate.
[0023] Its technical process is: design a new paradigm, build an experimental platform, collect data, and in the data processing stage, identify and classify through step-by-step linear discriminant analysis and typical...
