Use #eastUpSouthQTarget to get the quaternion from target to East-Up-South (EUS) coordinates instead. To determine a value analogous to the heading value, calculate the yaw, pitch, and roll values from #eastUpSouthQTarget. When the device is pointing downwards, i.e. perpendicular to the ground, heading is analoguous to roll, and when the device is upright in the device's default orientation mode, heading is analogous to yaw.
This is valid only for GARGeospatialTransform from GAREarth.cameraGeospatialTransform, and is 0 for all other GARGeospatialTransform objects. To get the yaw uncertainty, use #orientationYawAccuracy instead, which is analogous to the heading accuracy when the device is held upright in the default orientation mode.
