Differences in usability score and upper limb kinematics. (a). In this plot, HCP and IHP’s median of BBT-VR-C, BBT-VR-HT and MD-MR SUS scores are presented as histograms with error bars. Each error bar represents the 3rd quartile of the given test’s score. The * corresponds to a significant difference. (b). In this plot, HCP and IHP’s mean movement smoothness, as measured by the spectral arc length, are presented in the form histograms with error bars. Each error bar represents the positive standard deviation of the given test’s score. The * corresponds to a significant difference
