Syntax
Public Structure MotionReading _
Implements ISensorReading
public struct MotionReading : ISensorReading
The MotionReading type exposes the following members.
Properties
| Name | Description | |
|---|---|---|

Attitude | Gets the attitude (yaw, pitch, and roll) of the device, in radians. |
|
DeviceAcceleration | Gets the linear acceleration of the device, in gravitational units. |
|
DeviceRotationRate | Gets the rotational velocity of the device, in radians per second. |
|
Gravity | Gets the gravity vector associated with the MotionReading. |
|
Timestamp | Gets 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. |

Equals | Indicates whether this instance and a specified object are equal. (Inherited from ValueType.) |

Finalize | Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
|
GetHashCode | Returns the hash code for this instance. (Inherited from ValueType.) |
|
GetType | Gets the Type of the current instance. (Inherited from Object.) |
|
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
|
ToString | Returns the fully qualified type name of this instance. (Inherited from ValueType.) |

Remarks
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.
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.
