Hi @LBord.1 .
you can refer to this thread for a precise description of the calculation performed by the MotionSP library.
In particular, the Speed can be “estimated�? starting from the acceleration values through a numerical integration method.
One of the most used method is known as TRAPEZOIDAL Rule, and it has been implemented inside the MotionSP.
The “lambda�? factor is just a parameter fixed to 0.5, giving the opportunity to the user to change. In this way is possible to estimate the speed using a recursive formula as described below.
Note that every speed value is evaluated using two consecutive acceleration samples, the time sampling (DT = 1/ODR), and the previous speed value.
