SD Threshold for Idle?

[muschellij2]

What is the threshold for idle?

In the paper "Zee: Zero-Effort Crowdsourcing for Indoor Localization" it indicates 0.01

but the autocorrelation code uses 0.02

Line 228 in 364c00c

if (sd < 0.02):

and it is set 0.02 in main.py
https://github.com/hermanwongkm/OneStepAtATime/blob/master/main.py#L84

OneStepAtATime/main.py

Line 84 in 364c00c

if(sd < 0.02):

Also the cutoff for "DRIVING" is different between main and autocorrelation, which should be used?

elif (autoCorrelationValue > 0.4 and sd < 0.08):

elif (acChosen > 0.4 and sd < 0.05):
