Good morning,
Does anyone know if the Gyro axis in the watches are aligned with the Accelerometer axis in the X/Y/Z planes?
I kind of assumed that they would be, but without any way to test real data yet, if they are not aligned and are some random orientation, makes life much more complicated.
If they were aligned, and the watch was oriented, It would be very easy to translate a Gyro rate, for example 30 degree per second forward roll, into a new orientation of the watch and therefore orientation of the acceleration values.
