Upper body angles as output from Plug-in Gait

Upper body angles as output from Plug-in Gait

The following tables display the upper body segment angles from Plug-in Gait.

All upper body angles are calculated in rotation order YXZ.

As Euler angles are calculated, each rotation causes the axis for the subsequent rotation to be shifted. Xā€™ indicates an axis which has been acted upon and shifted by one previous rotation, Xā€™ā€™ indicates a rotation axis which has been acted upon and shifted by two previous rotations.
