HeadPosition.AltitudeInDegrees Property

Definition

Namespace:

Windows.Devices.Sensors

Gets the elevation of the user's head relative to the horizontal plane of the human presence sensor, in degrees.

public:
 property IReference<double> ^ AltitudeInDegrees { IReference<double> ^ get(); };

IReference<double> AltitudeInDegrees();

public System.Nullable<double> AltitudeInDegrees { get; }

var iReference = headPosition.altitudeInDegrees;

Public ReadOnly Property AltitudeInDegrees As Nullable(Of Double)

Property Value

IReference<Double>

Nullable<Double>

IReference<double>

The elevation of the user's head relative to the horizontal plane of the human presence sensor, in degrees.

This value has a range of -90 degrees to 90 degrees and is positive in the direction of the Y-axis.

Remarks

The angle between Z-axis and XZ-projection of the vector pointing from the sensor device to the center of the user's head and its XZ-projection. Range is constrained by the maximum and minimum altitude sensor properties.

The following image shows how azimuth and altitude are described by the human presence APIs.
