Disclosed is a motion digitizing and evaluating device, capable of preparing recordings or motion files more accurate—from several aspects—than those known so far, even without a permanent external reference signal. In addition to the inertial measurement units fixed to the separately moving body parts or spare parts of the examined person, living creature or objects, basic parts of the device are also the pressure-sensitive sole units and the pressure sensor gloves, thanks to which the location-changing movements can be truly tracked by the virtual bone system mapped by the software. With more accurate motion detection, the external magnetic orientation—which has so far been inevitable for such purposes in the previous systems—or the application of multi-axial magnetometers can be easily eliminated. A part of the patent is a strap vest for the more precise fixing of the strain-related sensors on the back.
