Figure 7From: Performance evaluation of a motor-imagery-based EEG-Brain computer interface using a combined cue with heterogeneous training data in BCI-Naive subjects Result of the comparison between homogeneous and heterogeneous experiment. The heterogeneous CV combination is higher than the homogeneous CV combination (p < 0.05). For the VC combination, the heterogeneous accuracy is lower than the homogeneous accuracy (p < 0.05).Back to article page
