markers

Hi,

We studied the gait model in which you have put marker coordinates. We
would like to do the same for the upper extremity, however we don’t
completely understand how it is done. Are the marker coordinates
defined in the local reference frames? And how did you calculate these
points, was this done outside of Anybody?

Hi Carolien

The model basically has two sets of identical markers;

The first set of the markers are attached to the bones so these marker
coordinates are defined in the local coordinate system of the bones segments.
These nodes has been fitted manually to the bones, their definition can be found
in the file MarkerPosOnBody.any.

The second set of markers are “free floating” and driven in space by measured
mocap data.

The free floating markers are then used as drivers for the equivalent markers on
the bones. This is done by specifying linear measures between equivalent marker
set and drive these measures.

There has been a webcast about the Gait model please log into the members area
