(a) SNR violin plots for GRASP (upper one) and GESTURE (lower one) to show SNR values (in dB) distribution of all trials on multiple days. The x-axis represents the number of days and the y-axis represents SNR values. The green, orange, and yellow lines indicate the mean value of all SNR values of trials on the same day in Task 1 (10% MVC), Task 2 (30% MVC), and Task 3 (50% MVC). The red and black line segments in (a) indicate the median and mean value of trials on the same day. (b) CCN radar plots for GRASP (upper one) and GESTURE (lower one). Curves with different colors represent the mean value of CCN values of trials on the same day. Each axis represents different grasps (GRASP) or hand gestures (GESTURE). The nearest number to each text indicating grasps or gestures is the mean value of CCN values of trials of the grasp or gesture.
