On-Device Features
Sentiance offers a variety of features whose processing happens strictly offline on the device. These are the on-device features that are available via the Sentiance SDK.
The features listed on this page must first be enabled by Sentiance for your app, before you can start using them. Please reach out to our support team to have a feature enabled.
Some features that are listed here are released as Early Access. Please check out our Production Readiness page to find out more.

Vehicle Crash Detection

This feature offers the ability to detect vehicle crashes (collisions) in real time, during trips. Sentiance processes various sensor and location data in real time on the device, in order to detect crashes and notify your app.
Crash data includes information such as location, magnitude of the detected peak, and confidence.
You can learn more about this feature in our Vehicle Crash Detection page.

Activation for Android

For Android apps, in order to activate vehicle crash detection and receive crash data, you must add the com.sentiance:sdk-crash-detection artifact as a dependency. You can then subscribe for vehicle crash events via the CrashDetectionApi class.
app/build.gradle
dependencies {
implementation(platform('com.sentiance:sdk-bom:<sentiance-version>'))
implementation('com.sentiance:sdk-crash-detection')
...
}

Activation for iOS

For iOS apps, crash detection is included in the main SDK framework. No additional steps are needed to activate it.

Activation for React Native

For React Native apps, to activate and access crash detection, install the @sentiance-react-native/crash-detection module.

Transport Classification

The Sentiance SDK processes various sensor and location data in real-time, directly on the device, to segment a user's trips into the various transport methods used, such as walking, biking, vehicle. The SDK uses Sentiance's state of the art deep learning model to achieve this.
The classification results are exposed in the user's context information, part of the user's recent events.

Activation for Android

For Android apps, this feature is included after adding a dependency on the com.sentiance:sdk-user-context or com.sentiance:sdk-lifestyle artifact.

Activation for iOS

For iOS apps, transport classification is included in the main SDK framework. No additional steps are needed to activate it.

Activation for React Native

For React Native apps, this feature is included after installing the @sentiance-react-native/user-context module.

User Current Context Information

A user's current context includes contextual information about the current state of the user. This includes things like:
  • Recent transport and stationary events, with venue type information if available.
  • The user's last known location.
  • The user's home and work venues, if detected.
  • The user's segments, if detected.
The population of this context information happens offline, on the device.

Activation for Android

For Android apps, in order to activate and access the user's current context information, you must add the com.sentiance:sdk-user-context artifact as a dependency. By default, this artifact excludes segment detection. To activate segment detection, you can add a dependency to the com.sentiance:sdk-lifestyle artifact instead, which will activate all lifestyle profiling features.
app/build.gradle
dependencies {
implementation(platform('com.sentiance:sdk-bom:<sentiance-version>'))
implementation('com.sentiance:sdk-user-context')
// or
implementation('com.sentiance:sdk-lifestyle')
...
}
You can then subscribe for user context updates, or request the context directly, via the UserContextApi class.

Activation for iOS

For iOS apps, the user's current context information is available via the main SDK framework. No additional steps are needed to activate it.

Activation for React Native

For React Native apps, to activate and access the user's current context, install the @sentiance-react-native/user-context module.

Venue Type Mapping & Home/Work Detection

The Sentiance SDK can enrich a user's stationary data with information about the significance of the stationary (i.e. home, work, or a point of interest), and type of venue (i.e. restaurant, fitness center, etc). This is possible with Sentiance's on-device, fully offline, venue type mapping feature.
The SDK uses venue data that is available for the entire globe, by downloading and storing it on the device on an as-needed basis. The data is divided into large geographic areas (town or city level), and is updated as the user navigates to different areas.
With the use of Sentiance's state of the art deep learning model for venue type mapping and home/work detection, the user's stationary data gets enriched, and refined as more data gets collected.
The venue information is exposed in the user's context, part of the user's recent stationary events, and as separate home and work venue properties.

Activation for Android

For Android apps, this feature is included after adding a dependency on the com.sentiance:sdk-user-context artifact.

Activation for iOS

For iOS apps, this feature is included in the main SDK framework. No additional steps are needed to activate it.

Activation for React Native

For React Native apps, this feature is included after installing the @sentiance-react-native/user-context module.

Segment Detection

The Sentiance SDK can enrich a user's context by assigning different segmentation profiles, e.g. heavy commuter, low/medium/high social activity, and more. This is possible with Sentiance's multi-platform decision engine which runs directly on the device. It consumes a user's timeline data, and in return produces segments that apply to the user.

Activation for Android

For Android apps, this feature is included after adding a dependency on the com.sentiance:sdk-lifestyle artifact.

Activation for iOS

For iOS apps, this feature is included in the main SDK framework. No additional steps are needed to activate it.

Activation for React Native

For React Native apps, to activate this feature, add a dependency on the com.sentiance:sdk-lifestyle artifact in your android app. For iOS apps, no additional steps are needed to activate it.
