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 | (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 | (Inherited from Object.) |
| GetType | (Inherited from Object.) |
| MemberwiseClone | (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 | (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.
