Sinusoid tracking experiment outcomes. (a) EMG signals and relative controlled DoF positions for a representative sinusoid. (b) Differences in performance metrics between subjects S1 and S2 and subjects S3 and S4. Asterisks denote statistically significant differences as computed by Wilcoxon rank sum tests. (c) Confusion matrices of the relative mean activity (RMA) and relative variance activity (RVA) from subjects S1 and S2 (experiment 2B). (d) Confusion matrices of the RMA and RVA from subjects S3 and S4 (experiment 2A).
