Parameters

Parameter Descriptions

Description

xrGetFineTrackingEyesInfoANDROID function gets the information for eye states and poses with higher precision than xrGetCoarseTrackingEyesInfoANDROID.

The runtime must return XR_ERROR_PERMISSION_INSUFFICIENT if the application does not have the android.permission.EYE_TRACKING_FINE permission.

The eyes information is resolved and relative to the base space at the time of the call to xrGetFineTrackingEyesInfoANDROID using XrEyesGetInfoANDROID::time, XrEyesGetInfoANDROID::baseSpace. The runtime must resolve the location defined by XrEyesGetInfoANDROID::baseSpace at the time of the call.

At any point of time both the position and direction of the eye pose is tracked or untracked. This means that the runtime must set both XR_SPACE_LOCATION_POSITION_TRACKED_BIT and XR_SPACE_LOCATION_ORIENTATION_TRACKED_BIT or clear both XR_SPACE_LOCATION_POSITION_TRACKED_BIT and XR_SPACE_LOCATION_ORIENTATION_TRACKED_BIT on the supplied XrEyesANDROID::eyes, and set XrEyesANDROID::mode to indicate the tracking states.
