Fig. 6

Bland Altman style plots showing the difference between OMCS and IMU sensors as a function of the mean of the two methods, for each component of displacement. Each plot is based on the samples collected for all subjects and conditions of walking speed. The line fitted to the plotted data is reported in blue. The upper and lower limits of agreement based on the regression approach described in [24] are reported in red; the green lines represent the constant limits of agreement computed without the regression-based correction
