Feasibility of a Hybrid Brain-Computer Interface for Advanced Functional Electrical Therapy
Figure 1
Block scheme of stage I of the hybrid BCI operation, SSVEP-BCI. While the subject gazes at one of the three objects equipped with LEDs flickering at frequencies , EEG (Oz-Cz) is analyzed for detecting associated SSVEP response. With the SSVEP detection, FES pattern for corresponding type of grasp is selected and stage II is initiated. The three graphs represent EEG (Oz-Cz) power spectra, normalized by the peak value.
