Using OpenSense with self IMU orientations #3264

Closed kai0122 closed 1 year ago

Hello,

I am trying to use the quaternions generated by multiple Shimmer IMUs to generate movements with the model using OpenSim. My original signal is recorded with a 360 degree turning movement. But after inverse kinematics, only the Pelvic IMU seems to be turning (correct), while the IMU's on the femur, tibia, calcn are not correct.

Do you have any suggestions on how to solve this issue? Thank you!
