how can I extract movement like up/down/left/right that is always referenced to gravity from linear acceleration, quaternions, roll pitch yaw, gravity 3d vector, 3d gyro accel

how can I extract movement like up/down/left/right that is always referenced to gravity from linear acceleration, quaternions, roll pitch yaw, gravity 3d vector, 3d gyro, 3d accel, 3d magnato?

This question is too broad. You are basically asking how to do general navigation from sensor data, which is not trivial. Maybe you could post a sample of some specific data you have and some code that you have tried and tell us what specific problems you are having.
