Gesture is linked with Gaze. When the user Air Taps on an object, it will return the HitInfo property only of the object Gazed on at that point of time. The HitInfo property is checked and updated by GazeManager. Air Tap on an object if HitInfo does not refer to any Game Object, the Air Tap will be skipped and no action will be taken. Input clicked event is driven by the GestureInput and InputManager class. OnInputClicked() method in SpeakerGestureHandler class finally handles the operation for a click event.
