public	accel: number[]
public	available: Boolean true if the acceloremeters are available on the device, false otherwise
public	gAccel: number[]
public	gravityVector: Object the gravity orientation vector based on accel including gravity.
public	kFilteringFactor: number
public	rotationRate: Object The accel rotation rate.
public	smoothedAcc: {"x": , "y": , "z": *}
public	userAcc: Object The accel values without gravity.

Method Summary

public	off()
public	on()
public	onDeviceMotion(event: *)
public	setup()

public	chain(component: Component) Adds a component to this chained component array
public	getChainedComponents(): Array Returns the array of attached children components
public	off() Deactivate the component
public	on() Activate the component A call to this method calls the setup method if it has not been run yet
public	postUpdate() Run code after the update of all components is run This empty method is usually overriden to perform post-update actions for the component It is called periodically by an internal Mobilizing mechanism
public	preLoad() preLoad the component This empty method is usually overriden to perform preLoad actions for the component.
public	preUpdate() Run code before the update of all components is run This empty method is usually overriden to perform pre-update actions for the component It is called once per component by an internal Mobilizing mechanism
public	prepare() prepare the component This empty method is usually overriden to perform preparation actions for the component, from external process as a server.
public	setup() Set's up the component This empty method is usually overriden to perform setup actions for the component This is where all the initialization (such as adding event listeners)should be done It is called automatically by an internal Mobilizing mechanism and should thus not be called directly
public	update() Update the component This empty method is usually overriden to perform update actions for the component It is called periodically by an internal Mobilizing mechanism

Public Constructors

public constructor() source

Motion gives access to the embbeded accelerometers data of you device. !WARNING! On iOS 13+ you must call on() in a user interaction (i.e "touchend" on Mobile Safari). See examples!

Override:

Component#constructor

Public Methods

public getSmoothedAcc(factor: Number): Object source

Method to get the filtered accel including gravity.

Params:

Name	Type	Attribute	Description
factor	Number		The number to use for the filtering aglorithm (0.07 gives good results)

Return:

Object

smoothedAcc object composed by x, y & z components

public off() source

Deactivate the component

Override:

Component#off

public on() source

Activate the component A call to this method calls the setup method if it has not been run yet

Override:

Component#on

public onDeviceMotion(event: *) source

Params:

Name	Type	Attribute	Description
event	*

public setup() source

Set's up the component This empty method is usually overriden to perform setup actions for the component This is where all the initialization (such as adding event listeners)should be done It is called automatically by an internal Mobilizing mechanism and should thus not be called directly

Override:

Component#setup

Private Methods

private computeGravityVector() source

Method to compute the gravity orientation vector based on accel including gravity. The result can also be get through the event onAccelerationGravityVector

private computeUserAcc() source
