AWARE: Pedometer

CI Status Version License Platform

The Pedometer sensor allows us to manages historic pedometer data which is provided by CMPedometer. The pedometer object contains step counts and other information about the distance traveled and the number of floors ascended or descended.

Requirements

iOS 10 or later

Installation

com.awareframework.ios.sensor.pedometer is available through CocoaPods.

  1. To install it, simply add the following line to your Podfile:
pod 'com.awareframework.ios.sensor.pedometer'
  1. Import com.awareframework.ios.sensor.pedometer library into your source code.
import com_awareframework_ios_sensor_pedometer
  1. Add a description of NSMotionUsageDescription into Info.plist

Public functions

PedometerSensor

  • init(config:PedometerSensor.Config?) : Initializes the pedometer sensor with the optional configuration.
  • start(): Starts the pedometer sensor with the optional configuration.
  • stop(): Stops the service.

PedometerSensor.Config

Class to hold the configuration of the sensor.

Fields

  • sensorObserver: PedometerObserver: Callback for live data updates.
  • interval : Int: A sampling duration (minute) of a sample. (default = 10)
  • enabled: Boolean Sensor is enabled or not. (default = false)
  • debug: Boolean enable/disable logging to Xcode console. (default = false)
  • label: String Label for the data. (default = "")
  • deviceId: String Id of the device that will be associated with the events and the sensor. (default = "")
  • dbEncryptionKey Encryption key for the database. (default = null)
  • dbType: Engine Which db engine to use for saving data. (default = Engine.DatabaseType.NONE)
  • dbPath: String Path of the database. (default = "aware_pedometer")
  • dbHost: String Host for syncing the database. (default = null)

Broadcasts

Fired Broadcasts

  • PedometerSensor.ACTION_AWARE_PEDOMETER fired when pedometer saved data to db after the period ends.

Received Broadcasts

  • PedometerSensor.ACTION_AWARE_PEDOMETER_START: received broadcast to start the sensor.
  • PedometerSensor.ACTION_AWARE_PEDOMETER_STOP: received broadcast to stop the sensor.
  • PedometerSensor.ACTION_AWARE_PEDOMETER_SYNC: received broadcast to send sync attempt to the host.
  • PedometerSensor.ACTION_AWARE_PEDOMETER_SET_LABEL: received broadcast to set the data label. Label is expected in the PedometerSensor.EXTRA_LABEL field of the intent extras.

Data Representations

PedometerSensor Data

Contains the raw sensor data.

Field Type Description
startDate Int64 The start time for the pedometer data by unixtime milliseconds since 1970
endDate Int64 The end time for the pedometer data by unixtime milliseconds since 1970
numberOfSteps Int64 The number of steps taken by the user.
distance Double The estimated distance (in meters) traveled by the user.
currentPace Double The current pace of the user, measured in seconds per meter.
currentCadence Double The rate at which steps are taken, measured in steps per second.
floorsAscended Double The approximate number of floors ascended by walking.
floorsDescended Double The approximate number of floors descended by walking.
averageActivePace Double The average pace of the user, measured in seconds per meter.
label String Customizable label. Useful for data calibration or traceability
deviceId String AWARE device UUID
label String Customizable label. Useful for data calibration or traceability
timestamp Int64 Unixtime milliseconds since 1970
timezone Int Raw timezone offset of the device
os String Operating system of the device (e.g., ios)

Example usage

var pedometer = PedometerSensor.init(PedometerSensor.Config().apply{config in
    config.debug  = true
    config.dbType = .REALM
    config.sensorObserver = Observer()
})
pedometer.start()
class Observer:PedometerObserver {
    func onPedometerChanged(data:PedometerData){
        // Your code here..
    }
}
