Accuracies (ACC) and information transfer rates (ITR) of the online BCI experiment (EEG2Code model). Shown are the average results of all subjects using random stimulation patterns and optimized stimulation patterns. ITRs are calculated using Eq 5 with N = 32 and T = 2.75s (including an inter-trial time of 0.75s).
