Phone Activity Recognition

Sensor parameters description for [PHONE_ACTIVITY_RECOGNITION]:

Key                                                               Description
[CONTAINER][ANDROID] Data stream container (database table, CSV file, etc.) where the activity data from Android devices is stored (the AWARE client saves this data on different tables for Android and iOS). This can be a single container or an array of containers
[CONTAINER][IOS] Data stream container (database table, CSV file, etc.) where the activity data from iOS devices is stored (the AWARE client saves this data on different tables for Android and iOS). This can be a single container or an array of containers
[EPISODE_THRESHOLD_BETWEEN_ROWS] Difference in minutes between any two rows for them to be considered part of the same activity episode

Parameters description for [PHONE_ACTIVITY_RECOGNITION][PROVIDERS][RAPIDS]:

Key                              Description
[COMPUTE] Set to True to extract PHONE_ACTIVITY_RECOGNITION features from the RAPIDS provider
[FEATURES] Features to be computed, see table below
[ACTIVITY_CLASSES][STATIONARY] An array of the activity labels to be considered in the STATIONARY category choose any of still, tilting
[ACTIVITY_CLASSES][MOBILE] An array of the activity labels to be considered in the MOBILE category choose any of on_foot, walking, running, on_bicycle

Features description for [PHONE_ACTIVITY_RECOGNITION][PROVIDERS][RAPIDS]:

Feature Units Description
count rows Number of episodes.
mostcommonactivity activity type The most common activity type (e.g. still, on_foot, etc.). If there is a tie, the first one is chosen.
countuniqueactivities activity type Number of unique activities.
durationstationary minutes The total duration of [ACTIVITY_CLASSES][STATIONARY] episodes of still and tilting activities
durationmobile minutes The total duration of [ACTIVITY_CLASSES][MOBILE] episodes of on foot, running, and on bicycle activities
durationvehicle minutes The total duration of [ACTIVITY_CLASSES][VEHICLE] episodes of on vehicle activity

Assumptions/Observations

  1. iOS Activity Recognition names and types are unified with Android labels:

    iOS Activity Name Android Activity Name Android Activity Type
    walking walking 7
    running running 8
    cycling on_bicycle 1
    automotive in_vehicle 0
    stationary still 3
    unknown unknown 4

  2. In AWARE, Activity Recognition data for Android and iOS are stored in two different database tables, RAPIDS automatically infers what platform each participant belongs to based on their participant file.
