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.
