CARP Movisens Sampling Package

pub package

This library contains a sampling package for sampling data from the Movisens Move4 and ECGMove4 devices to work with the carp_mobile_sensing package. This packages supports sampling a Movisens data as configured using the MovisensMeasure. The type is:

  • dk.cachet.carp.movisens

See the wiki for further documentation, particularly on available measure types and sampling schemas.

When running, the MovisensProbe of this package return different MovisensDatum formats (note that the package defines its own namespace of dk.cachet.carp.movisens):

  • dk.cachet.carp.movisens.met_level
  • dk.cachet.carp.movisens.met
  • dk.cachet.carp.movisens.hr
  • dk.cachet.carp.movisens.hrv
  • dk.cachet.carp.movisens.is_hrv_valid
  • dk.cachet.carp.movisens.body_position
  • dk.cachet.carp.movisens.step_count
  • dk.cachet.carp.movisens.movement_acceleration
  • dk.cachet.carp.movisens.tap_marker
  • dk.cachet.carp.movisens.battery_level
  • dk.cachet.carp.movisens.connection_status

NOTE: Version 0.5.0 is migrated to AndroidX. This should not result in any functional changes, but it requires any Android apps using this plugin to also migrate if they're using the original support library. See Flutter AndroidX compatibility

iOS Integration

iOS is not supported.

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, a MovisensMeasure can be added to a study protocol like this.

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

  // create a study protocol using a local file to store data
  CAMSStudyProtocol protocol = CAMSStudyProtocol()
    ..name = 'Track patient movement'
    ..owner = ProtocolOwner(
      id: 'AB',
      name: 'Alex Boyon',
      email: 'alex@uni.dk',
    )
    ..dataEndPoint = FileDataEndPoint(
      bufferSize: 500 * 1000,
      zip: true,
      encrypt: false,
    );

  // define which devices are used for data collection - both phone and Movisens
  Smartphone phone = Smartphone();
  DeviceDescriptor movisens = DeviceDescriptor();

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

  // adding a movisens measure
  protocol.addTriggeredTask(
      ImmediateTrigger(), // a simple trigger that starts immediately
      AutomaticTask(name: 'Movisens Task')
        ..addMeasure(MovisensMeasure(
            type: MovisensSamplingPackage.MOVISENS,
            measureDescription: {
              'en': MeasureDescription(
                name: 'Movisens ECG device',
                description:
                    "Collects heart rythm data from the Movisens EcgMove4 sensor",
              )
            },
            enabled: true,
            address: '06-00-00-00-00-00',
            deviceName: "ECG-223",
            height: 178,
            weight: 77,
            age: 32,
            gender: Gender.male,
            sensorLocation: SensorLocation.chest)),
      movisens);
