Development of Single-Channel Hybrid BCI System Using Motor Imagery and SSVEP

Figure 8

Classification accuracies of 32-, 3- (from [26]), and single-channel MI + SSVEP hybrid systems in a two-class task. The black bars represent the results of this study. The three- and single-channel systems utilize EEG electrodes located in the central area (C3-Cz-C4, C3, and C4, resp.).
