plotMVNXData

This script was created to visualise and compare data from different segments recorded via the {{XSENS}}. Therefore several diagrams issued showing the development of acceleration, velocity and positions (regarding a global center) of different segments during the running time of the record. The diagrams are either showing the development of single components (X, Y, Z) of the plotted variables, or the calculated absolute vectors of these components. Some example outputs are shown below.

Example output of R/plotMVNXData:

The global coordinate system achses are defined as follows:

  • X: pointing to the local magnetic north
  • Y: according to the right hand coordinates (pointing the west)
  • Z: pointing up

Comparison of Two Segments

The segments LeftFoot and RightFoot during several steps of a natural walk are shown in the gallery below.

Comparison of Three Segments

The segments LeftFoot, RightFoot and Pelvis during several steps of a natural walk are shown in the gallery below.

Please note that the comparison diagram for the absolute velocities with the euclidian distance between two segments only is available when two segments are compared.
