Differentiate between left and right gait events

[rmndrs89]

It is generally difficult to distinguish between left and right gait events from a lower back-worn IMU. However, some example algorithms exist and it might be nice to have them implemented. A recent one applied a machine learning classifier, and maybe we could do somehting likes this and then compare to the McCamley naive implementation?

I guess with Elke's Keep Control and the Mobilise-D dataset, we can validate the left/right assignment easily from the foot-worn IMUs.
