* The GazeTracker (e.g. ``USFGameInstance::Get()->GetGazeTracker()``) provides:
*``GetCurrentGazeTarget()``: returning the name (``TargetName`` or actor name) of the currently gaze at target or an empty string if nothing "gazeable" is looked at.
*``LaunchCalibration()`` to launch a calibration from code.
* ~~:warning: **NOT IMPLEMENTED YET** :warning:~~ (implemented in feature/gaze_logging branch) logs the currently gaze at target name and the gaze direction per frame into a separate file per participant. The participant's gaze tracking logs are located in the StudyLogs/GazeTrackingLogs folder.
