|`[CONTAINER][IOS]`| Data stream [container](../../datastreams/data-streams-introduction/) (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)
|
|
|`[EPISODE_THRESHOLD_BETWEEN_ROWS]` | Difference in minutes between any two rows for them to be considered part of the same activity episode

|
|`[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`
|
|
|`[ACTIVITY_CLASSES][VEHICLE]` | An array of the activity labels to be considered in the `VEHICLE` category choose any of `in_vehicule`
|

|
|
|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
|

|
!!! note "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](../../setup/configuration/#participant-files). |
