Bland-Altman Plots for each combination of task/population. Subplot (a) presents the results for ML direction, subplot (b) for the AP direction and subplot (c) for the total path length. Y axis of each plot presents the difference between FP and WBB, while X axis presents the average between the two measures. All the plots show a decrease in accuracy of the WBB with respect to the FP as the magnitude of the estimated value increases
