C Specification

The XrSystemFaceTrackingPropertiesANDROID structure is defined as:

// Provided by XR_ANDROID_face_tracking
typedef struct XrSystemFaceTrackingPropertiesANDROID {
    XrStructureType    type;
    void*              next;
    XrBool32           supportsFaceTracking;
} XrSystemFaceTrackingPropertiesANDROID;

Members

Member Descriptions

  • type is the XrStructureType of this structure.

  • next is NULL or a pointer to the next structure in a structure chain. No such structures are defined in core OpenXR or this extension.

  • supportsFaceTracking is an XrBool32 indicating if current system supports face tracking.

Description

Important
Permissions

Android applications must have the android.permission.FACE_TRACKING permission listed in their manifest. The android.permission.FACE_TRACKING permission is considered a dangerous permission. The application must request the permission at runtime to use these functions:

(protection level: dangerous)

An application inspects whether the system is capable of face tracking by extending the XrSystemProperties with an XrSystemFaceTrackingPropertiesANDROID structure when calling xrGetSystemProperties.

If and only if a runtime returns XR_FALSE for supportsFaceTracking, the runtime must return XR_ERROR_FEATURE_UNSUPPORTED from xrCreateFaceTrackerANDROID.

Valid Usage (Implicit)
