Gyroscope Class
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Provides Windows Phone applications access to the device’s gyroscope sensor.
Microsoft.Devices.Sensors::SensorBase<GyroscopeReading>
Microsoft.Devices.Sensors::Gyroscope
Assembly: Microsoft.Devices.Sensors (in Microsoft.Devices.Sensors.dll)
XMLNS for XAML: Not mapped to an xmlns.
The Gyroscope type exposes the following members.
| 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<TSensorReading>.) |
| IsDataValid | Gets the validity of the sensor’s data. (Inherited from SensorBase<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<TSensorReading>.) |
| Name | Description | |
|---|---|---|
 | Dispose | Releases the managed and unmanaged resources used by the sensor. (Inherited from SensorBase<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<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<TSensorReading>.) |
| Stop | Stops acquisition of data from the sensor. (Inherited from SensorBase<TSensorReading>.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Name | Description | |
|---|---|---|
 | CurrentValueChanged | Occurs when new data arrives from the sensor. (Inherited from SensorBase<TSensorReading>.) |
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.
