Accelerometer data‏

[deleted6]

Hi!
I am building an app where I have to compare accelerometer data. That is, I am calculating vectors, and then using cosine similarity to compare them. Now this app is supposed to be cross-platform, I've registered the main data (ie the one that the others compare to) on an Android device, then I launched the app on a Linux (non-Android) device. Even though I am doing the same thing, my similarity is around 0 (it is between -1 - complete opposite and 1 - exactly the same). Could this be due to the platform change, or does Qt perform some kind of normalization?
Thanks.

Hi and welome to devnet,

Are you user you have an accelerometer on your Linux device ? If so is it known to Qt ? You should be able to identify the plugin used by launching your application with QT_DEBUG_PLUGINS=1 set.

@SGaist Yes it works perfectly, it's just that the data is different (because one system uses QtSensors/Android and the other QtSensors/Linux, so I am asking if Qt performs normalization)
