Figure 4

ROC curves obtained for each movement. Panels A-G correspond to the results for each of the seven movements (SA, SF, SR, EF, ES, WE, and WR, respectively). On each panel, colored lines represent the different subjects, while the black line shows the average of the six subjects. Circles on each line represent the point of the curve with equal sensitivity and specificity, which are considered the optimal working points. Diagonal gray dashed lines represent the performance of a random classifier. Each legend box contains the AUC for each subject and the average of them.
