I have got data from accelerometer,gyroscope and magnetometer .It also give me Euler angle data in X,Y,Z coordinates in degree.

this is the data from hand movement where I am holding a weight in my hand and moving it up and down.I have to find out out of these given data which data is useful,I need to calculate the kinematics of joint angles,range of motion and transform the data from local coordinates to cartesian coordinates.I also need to find out position vector of centre of mass and weight.
