"Acceleration without g" algorithm
#4
The algorithm that subtracts Earth‘s acceleration is provided by the OS. Both options, acceleration with g in- and excluded, are directly obtained from the sensor APIs. You could (likely) do the same with your Android framework without wondering how to implement any sensor fusion concepts…

The accelerometer “sees” Earth‘s acceleration, however, on many occasion that‘s not what you want in scientific experiments, centrifugal acceleration being one of these examples like you said. Sensor fusion with gyroscope and magnetometer allows to identify the direction of Earth‘s acceleration and accordingly “remove” it. Since the latest release of phyphox, there is also this virtual gravity sensor included in https://phyphox.org/wiki/index.php/Phyph...le:_sensor
