Hybrid brain-computer interface system based on steady-state visual evoked potentials and attentional EEG

Summary: Aiming at the multi-classification research of attentional EEG signals and the expansion of the experimental paradigm of brain-computer interface systems, a stableHybrid brain-computer interface system of state visual evoked potential (SSVEP) and attentional EEG.First, the multi-level classification of attentional EEG was explored, and a fusion was designed.An attentional paradigm for spatial attention and mental tasks to improve the classification performance of attentional EEG.In the brain-computer interface experiment, use αwave blocking signal to achieveSSVEPand attention-induced interface switching;SSVEPSignals are used to control the movement of the robot; attention levels are used to change the speed of the robot's movement.Experiment recruited10
