摘要：

Current literature shows the interesting opportunities of inertial measurement units (IMUs) for outdoor motion capturing. This study validated the accuracy of the TEA ergo IMU for full body joint angles tracking in diverse activities. One subject performed three exercises, consisting of a gait pattern, limb movements and cyclical arm movements. Comparison is Vicon infrared markers. For walking, the average root mean square error (RMSE) is 1.9 degrees for flexion/extension, 2.6 degrees for abduction/adduction and 3.7 degrees for rotation angles. The accuracy of the IMU decreases for fast and complicated limb movements (RMSE <= 8.0 degrees). However, these values are still acceptable, which demonstrates the applicability of the IMUs for use in various domains.
