a Devices used. b Average stimuli differentiation minimum distance across fingers and areas, where the magnitude of the distance is reflected in the color intensity of the areas. c Stimuli differentiation minimum distance across fingers and areas, where the median is denoted with a notch, + are outliers, and each box’s limits are the second and third quartiles. ∗, ∗∗, and ∗∗∗ represent statistical significance with p ≤ 0.05, p ≤ 0.01, and p ≤ 0.001, respectively.
