() Studied angles: swivel angle plus the shoulder, elbow, and wrist joint angles () Reference angles: obtained from custom-made inertial MOCAP; homologation-calibration of the readings is not reported () Movements: compound movements () Sensitivity analysis: no
Mean RMSE: 4.8 deg. (best-case scenario)
Hybrid exoskeleton-optical MOCAP
() Studied angles: shoulder angles () Reference angles: simulated () Movements: 1-DOF and multi-DOF shoulder movements () Sensitivity analysis: method accuracy w.r.t. marker position errors produced by marker drift or calibration errors
(a) Mean RMSE: 0.9 deg. (assuming no marker drift or calibration errors) (b) Mean RMSE: 3.6 deg. (with marker drift or calibration errors up to 20 mm)
