There are four different Biomech Markersets (Motive 1.9): Biomech (54), Biomech(49), Biomech Upper Body (27), and Biomech Lower Body (26). When attaching the markers, you should reference the skeleton avatar from the Skeleton Pane for relative locations. The following charts provide anatomical conventions as well as additional descriptions to where each marker should be place. Find respective markers from the chosen markerset and use the chart for more accurate placements.
For Motive 1.10 and above, Biomech Markersets have been replaced with Rizzoli Markerset. Only the Biomech Markerset (49) will be available. Please read more at Rizzoli Markerset.
List of Biomech Markersets
Asymmetry is the key to avoiding the congruency for tracking multiple markersets. When there are more than one similar marker arrangements in the volume, marker labels may be confused. Thus, it is beneficial to place segment makers — joint markers must always be placed on anatomical landmarks — in asymmetrical positions for similar rigid bodies and skeletal segments. This provides a clear distinction between two similar arrangements. Furthermore, avoid placing markers in a symmetrical shape within the segment as well. For example, a perfect square marker arrangement will have ambiguous orientation and frequent mislabels may occur throughout the capture. Instead, follow the rule of thumb of placing the less critical markers in asymmetrical arrangements.
