MotionReading Structure

MotionReading Structure

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Contains information about the orientation and movement of the device.

Namespace:  Microsoft.Devices.Sensors
Assembly:  Microsoft.Devices.Sensors (in Microsoft.Devices.Sensors.dll)

public struct MotionReading : ISensorReading

The MotionReading type exposes the following members.

Public propertyAttitudeGets the attitude (yaw, pitch, and roll) of the device, in radians.
Public propertyDeviceAccelerationGets the linear acceleration of the device, in gravitational units.
Public propertyDeviceRotationRateGets the rotational velocity of the device, in radians per second.
Public propertyGravityGets the gravity vector associated with the MotionReading.
Public propertyTimestampGets a timestamp indicating the time at which the MotionReading was calculated. This can be used to correlate readings across sensors and provide additional input to algorithms that process raw sensor data.

Public methodEqualsIndicates whether this instance and a specified object are equal. (Inherited from ValueType.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeReturns the hash code for this instance. (Inherited from ValueType.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns the fully qualified type name of this instance. (Inherited from ValueType.)

The Motion class processes data from multiple device sensors, including the Compass, Gyroscope, and Accelerometer sensors and computes the current orientation and acceleration of the device.

To obtain a MotionReading object, create a Motion object, call the Start() method, and then use the CurrentValue property or implement a handler for the CurrentValueChanged event.


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.
