CARP Movisens Sampling Package

This library contains a carp_mobile_sensing (CAMS) sampling package for collecting data from Movisens devices:

• Move 4
• EcgMove 4
• EdaMove 4

NOTE - as stressed by Movisens, none of the Movisens devices are medical devices. Do not use them for medical purposes.

This packages supports sampling of the following Measure types:

• dk.cachet.carp.movisens.activity – Physical activity like body positions, step count, inclination, acceleration, and metabolic (MET) levels.
• dk.cachet.carp.movisens.hr - Heart Rate (HR), HR Variability (HRV), Mean HR
• dk.cachet.carp.movisens.eda - Elecrodermal Activity
• dk.cachet.carp.movisens.skin_temperature - Skin temperature.
• dk.cachet.carp.movisens.tap_marker - Markers of user tapping on the sensor.

These measures collect different types of data (note that the package defines its own namespace of dk.cachet.carp.movisens...):

Physical Activity:

• dk.cachet.carp.movisens.activity.steps
• dk.cachet.carp.movisens.activity.body_position
• dk.cachet.carp.movisens.activity.inclination
• dk.cachet.carp.movisens.activity.movement_acceleration
• dk.cachet.carp.movisens.activity.met_level
• dk.cachet.carp.movisens.activity.met

Heart Rate:

• dk.cachet.carp.movisens.hr.hr_mean
• dk.cachet.carp.movisens.hr.hrv
• dk.cachet.carp.movisens.hr.is_hrv_valid

Misc:

• dk.cachet.carp.movisens.eda
• dk.cachet.carp.movisens.skin_temperature
• dk.cachet.carp.movisens.tap_marker

For understanding how to use the Movisens Devices, please consult the Movisens Documentation.

See the wiki for further documentation on how to use the CARP Mobile Sensing (CAMS) framework. See the CARP Mobile Sensing App for an example of how to build a mobile sensing app in Flutter. For Flutter plugins for other CARP products, see CARP Mobile Sensing in Flutter.

If you're interested in writing you own sampling packages for CAMS, see the description on how to extend CARP on the wiki.

Installing

To use this package, add the following to you pubspc.yaml file. Note that this package only works together with carp_mobile_sensing.

dependencies:
  carp_core: ^latest
  carp_mobile_sensing: ^latest
  carp_movisens_package: ^latest
  ...

Android Integration

Add the following to your app's manifest.xml file located in android/app/src/main:

  <uses-permission android:name="android.permission.BLUETOOTH" />
  <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
  <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

Update the Android minSdkVersion to at least 19 in the android/app/build.gradle file.

iOS Integration

Add the following to your ios/Runner/Info.plist file:

<dict>
  <key>NSBluetoothAlwaysUsageDescription</key>
  <string>Need BLE permission</string>
  <key>NSBluetoothPeripheralUsageDescription</key>
  <string>Need BLE permission</string>
  <key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
  <string>Need Location permission</string>
  <key>NSLocationAlwaysUsageDescription</key>
  <string>Need Location permission</string>
  <key>NSLocationWhenInUseUsageDescription</key>
  <string>Need Location permission</string>

Usage

To use this package, import it into your app together with the carp_mobile_sensing package:

import 'package:carp_core/carp_core.dart';
import 'package:carp_mobile_sensing/carp_mobile_sensing.dart';
import 'package:movisens_package/movisens.dart';

Before creating a study and running it, register this package in the SamplingPackageRegistry.

 SamplingPackageRegistry().register(MovisensSamplingPackage());

Once the package is registered, Movisens measures can be added to a study protocol like this.

  // register this sampling package before using its measures
  SamplingPackageRegistry().register(MovisensSamplingPackage());

  // Create a study protocol
  StudyProtocol protocol = StudyProtocol(
    ownerId: 'owner@dtu.dk',
    name: 'Movisens Example',
  );

  // define which devices are used for data collection - both phone and Movisens
  Smartphone phone = Smartphone();
  MovisensDevice movisens = MovisensDevice(
    deviceName: 'MOVISENS Sensor 02655',
    sensorLocation: SensorLocation.Chest,
    sex: Sex.Male,
    height: 175,
    weight: 75,
    age: 25,
  );

  protocol
    ..addPrimaryDevice(phone)
    ..addConnectedDevice(movisens);

  // adding a movisens measure
  protocol.addTaskControl(
      ImmediateTrigger(),
      BackgroundTask(name: 'Movisens Task', measures: [
        Measure(type: MovisensSamplingPackage.ACTIVITY),
      ]),
      movisens);

This protocol collects physical activity data (steps, inclination, etc.) from a Movisens device with the name MOVISENS Sensor 02655. The default Movisens names of devices are MOVISENS Sensor <serial>, where serial is the 5-digit serial number written on the back of the device. Once this protocol is deployed on a phone and connected to a Movisens device using Bluetooth, it will start to collect the physical activity data from the device. Please see the CARP Mobile Sensing App for an example of how to build a mobile sensing app that can handle protocols and connect to devices.
