C Specification

The XrSystemEyeTrackingPropertiesFB structure is defined as:

// Provided by XR_FB_eye_tracking_social
typedef struct XrSystemEyeTrackingPropertiesFB {
    XrStructureType    type;
    void*              next;
    XrBool32           supportsEyeTracking;
} XrSystemEyeTrackingPropertiesFB;

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.

  • supportsEyeTracking is an XrBool32, indicating if the current system is capable of receiving eye tracking input.

Description

An application can inspect whether the system is capable of eye tracking input by extending the XrSystemProperties with XrSystemEyeTrackingPropertiesFB structure when calling xrGetSystemProperties.

If a runtime returns XR_FALSE for supportsEyeTracking, the runtime must return XR_ERROR_FEATURE_UNSUPPORTED from xrCreateEyeTrackerFB.
