Bluetooth Features

We use all features from RAPIDS-Bluetooth, including the number of scans of participants' own devices and others' devices, as well as the unique count of these devices.

Feature Name	Unit	Description
`countscans`	scans	Number of scans (rows) from the devices sensed during a time segment instance. The more scans a bluetooth device has the longer it remained within range of the participant’s phone.
`uniquedevices`	devices	Number of unique bluetooth devices sensed during a time segment instance as identified by their hardware addresses.
`meanscans`	scans	Mean of the scans of every sensed device within each time segment instance.
`stdscans`	scans	Standard deviation of the scans of every sensed device within each time segment instance.
`countscansmostfrequentdevicewithinsegments`	scans	Number of scans of the most sensed device within each time segment instance.
`countscansleastfrequentdevicewithinsegments`	scans	Number of scans of the least sensed device within each time segment instance.
`countscansmostfrequentdeviceacrosssegments`	scans	Number of scans of the most sensed device across time segment instances of the same type.
`countscansleastfrequentdeviceacrosssegments`	scans	Number of scans of the least sensed device across time segment instances of the same type per device.
`countscansmostfrequentdeviceacrossdataset`	scans	Number of scans of the most sensed device across the entire dataset of every participant.
`countscansleastfrequentdeviceacrossdataset`	scans	Number of scans of the least sensed device across the entire dataset of every participant.
