Ergonomics and Human Factors with Inertial Sensor Technology
Xsens MVN Analyze is a full-body motion analysis system with 17 inertial motion trackers. Based on a biomechanical model MVN Analyze provides 3D joint angles, body Center of Mass as well as spatial parameters such as segment position and orientation.
When doing ergonomic measurements with IMU technology, one of the first setbacks you would typically encounter were metal objects. These objects have their own magnetic field and create distortions. The Achilles heel of Inertial Motion Capture has always been body segment drift due to magnetic field distortions. Typically, metallic objects and/or electrical engines in the vicinity could cause errors and drift in the data over time, causing unusable data or the need for additional and costly post-processing.
With the new MVN engine, we are leaving drift due to magnetic distortions behind us. Due to batch processing and a new framework we are fully magnetic immune. In total 10 years of manhours went into the development of the new engine, advanced soft tissue modeling is also included. Due to this giant next step in full body motion capturing Xsens is able to ensure consistent and reliable data in any environment, so also near the production line or even inside a car.
