1 MVN BIOMECH Awinda 3D KINEMATIC MEASUREMENT SYSTEM WITH WIRELESS TRACKERS

2 MVN BIOMECH Awinda is an ambulatory 3D human kinematic measurement system like the MVN BIOMECH system. MVN BIOMECH Awinda uses fully wireless motion trackers allowing increased freedom of movement of the subject, reduced preparation time and lower on-body weight of the system. The MVN BIOMECH Awinda system is based on Xsens proven technology. Using state of the art inertial motion trackers, sensor fusion algorithms, specialized wireless protocols and validated biomechanical models, highly accurate kinematic data is generated. MVN BIOMECH Awinda can be used indoors and outdoors regardless of terrain or lighting conditions. The results of MVN BIOMECH Awinda trials require minimal postprocessing as there is no occlusion or lost markers. Exported MVN BIOMECH Awinda data can be easily used in other software applications.
