Figure 9.

Example of an erroneous classification in an opened-loop trial. The image corresponds to the training trial 5 of subject S4. The poor %MI classification (52.8%) produced three FP and an Acc of 37.5%. If the attention paradigm had been considered, the three FP marked by the arrows would not have been computed. However, the exoskeleton would have been activated for a shorter period of time (between 33 and 38 s), stopping before the count event starts. This would have had a 50% Acc as the stop would have been commanded before the MI period ended. Compare Table 1 results for both paradigms of training trial 5 of S4.
