"Acceleration without g" algorithm

[Jens Noriʇzsɔɥ]

The Android and iOS APIs support the “acceleration without g” right away (at least, as long as the required sensors are built-in) so there is no specific algorithm in phyphox. On other systems like microcontrollers, there are libraries supporting the so-called “sensor fusion” in order to remove “g” or compute an absolute position in space.

I find this series on sensor fusion rather instructive: https://www.youtube.com/watch?v=6qV3YjFppuc (if you want to go the hard way and implement it yourself )
