[COMPUTE] Set to True to extract EMPATICA_ACCELEROMETER features from the DBDP provider
[FEATURES] Features to be computed, see table below


Feature Units Description
maxmagnitude m/s2 The maximum magnitude of acceleration (\(\|acceleration\| = \sqrt{x^2 + y^2 + z^2}\)).
minmagnitude m/s2 The minimum magnitude of acceleration.
avgmagnitude m/s2 The average magnitude of acceleration.
medianmagnitude m/s2 The median magnitude of acceleration.
stdmagnitude m/s2 The standard deviation of acceleration.


  1. Analyzing accelerometer data is a memory intensive task. If RAPIDS crashes is likely because the accelerometer dataset for a participant is too big to fit in memory. We are considering different alternatives to overcome this problem, if this is something you need, get in touch and we can discuss how to implement it.
