Inertial motion capture works by tracking the 3D orientation of the body parts, so by definition is a kind of technology that makes really hard to achieve things like touching one body part with another.
In order to get closer the body proportions of the avatar should match the ones of the person wearing the suit. Currently the way to achieve this is to modify the armature using blender editing tools. We plan to add an easier way to customize the armature proportions but we are currently focusing in other developments as I described above. I forgot to include pose-calibration among those, we are currently focusing on improving the arms.
What I can comment about the video you sent me:
The base sensor is really important for the rest of the pose, but is by far the harder one to position. Make sure to tighten the elastic bands that hold it, and that the KCeptor sits in the place where the sacrum is closer to the skin surface, right above both gluteous muscles, as described in the documentation. Also try to separate as much as possible the "belt" that carries the rpi and battery. I'm able to tell that this KC might not be correctly positioned because when you go down to touch your feet the hips remain practically in the same position, preventing the whole upper part to go down.
There seems to be an issue with the left foot. Does that KC give you correct results when tested alone?
