Description
An application can inspect whether the system is capable of receiving face tracking input by extending the XrSystemProperties with XrSystemFaceTrackingProperties2FB structure when calling xrGetSystemProperties.
If an application calls xrCreateFaceTracker2FB only with unsupported
XrFaceTrackerCreateInfo2FB::requestedDataSources
, the runtime
must return XR_ERROR_FEATURE_UNSUPPORTED
from
xrCreateFaceTracker2FB.
For example, if an application calls xrCreateFaceTracker2FB only with
XR_FACE_TRACKING_DATA_SOURCE2_AUDIO_FB
in
XrFaceTrackerCreateInfo2FB::requestedDataSources
when the
runtime returns XR_FALSE
for supportsAudioFaceTracking
, the
runtime must return XR_ERROR_FEATURE_UNSUPPORTED
from
xrCreateFaceTracker2FB.
