Results for the forward MDRT. (a) Comparison of the measured displacement provided by the depth camera (solid blue) and the inertial sensor (dashed red) for a representative participant. The positions of the defined control points are also shown; (b–d) mean time (with CI 95%), mean angular displacement (with CI 95%) and mean angular velocity (with CI 95%), respectively, over all the participants for the intervals defined by the control points; (e) Pearson Correlation Coefficient (r) (p < 0.005) between the devices for all the measured variables. (Time is expressed in seconds, angular displacement in degrees, and angular velocity in degrees per second).
