Fig. 3From: Psychometric characterization of incidental feedback sources during grasping with a hand prosthesisOverall JNDs for Exp I. The boxplots represent the overall JNDs across subjects for each feedback condition (SND in blue, VIS in red, VIS + SND in green) at the low (left) and high (right) standard-stimulus level, with the horizontal line indicating the median JND (also given as number), the box the interquartile range, the whiskers the range, and the pluses the outliers. Statistically significant differences between feedback conditions or between low and high levels within one feedback condition are depicted by asterisksBack to article page
