Syntax

Public NotInheritable Class Gyroscope _
    Inherits SensorBase(Of GyroscopeReading)

public sealed class Gyroscope : SensorBase<GyroscopeReading>

<Gyroscope .../>

The Gyroscope type exposes the following members.

Constructors

	Name	Description
	Gyroscope	Initializes a new instance of the Gyroscope class.

Properties

	Name	Description
	CurrentValue	Gets an object that implements ISensorReading that contains the current value of the sensor. This object will be one of the following types, depending on which sensor is being referenced: AccelerometerReading, CompassReading, GyroscopeReading, MotionReading. (Inherited from SensorBase<(Of <(TSensorReading>)>).)
	IsDataValid	Gets the validity of the sensor’s data. (Inherited from SensorBase<(Of <(TSensorReading>)>).)
	IsSupported	Gets or sets whether the device on which the application is running supports the gyroscope sensor.
	TimeBetweenUpdates	Gets or sets the preferred time between CurrentValueChanged events. (Inherited from SensorBase<(Of <(TSensorReading>)>).)

Methods

	Name	Description
	Dispose	Releases the managed and unmanaged resources used by the sensor. (Inherited from SensorBase<(Of <(TSensorReading>)>).)
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from SensorBase<(Of <(TSensorReading>)>).)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	Start	Starts acquisition of data from the sensor. (Inherited from SensorBase<(Of <(TSensorReading>)>).)
	Stop	Stops acquisition of data from the sensor. (Inherited from SensorBase<(Of <(TSensorReading>)>).)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Top

Events

	Name	Description
	CurrentValueChanged	Occurs when new data arrives from the sensor. (Inherited from SensorBase<(Of <(TSensorReading>)>).)

Remarks

The gyroscope sensor is used to determine the rotational velocity of the device in each axis. You can use the values obtained from the gyroscope sensor to determine how quickly a device is rotating about each axis. You can then integrate these values over time to determine how far the device has rotated since you began sampling. Because a gyroscope measures rotational velocity and not angle, it is susceptible to issues related to drift. If you are interested in determining the attitude (yaw, pitch, and roll) of the device, you should use Motion instead.

Capabilities

If you use this API in your app, you must specify the following capabilities in the app manifest. Otherwise, your app might not work correctly or it might exit unexpectedly.
