Classification accuracies using EOG versus EEG. For each participant, only those direction pairs are depicted which yielded significant classification results based on EEG and/or EOG. Notably, high accuracy for EEG-based classification usually comes with low accuracy for EOG-based classification, and vice versa. This suggests a dissociation between EEG- and EOG-based classification.
