A computing system for displaying a GUI element on a natural user interface is described herein. The computing system includes a display configured to display a natural user interface of a program executed on the computing system, and a gesture sensor configured to detect a gesture input directed at the natural user interface by a user. The computing system also includes a processor configured to execute a gesture-recognizing module for recognizing a registration phase, an operation phase, and a termination phase of the gesture input, and a gesture assist module configured to first display a GUI element overlaid upon the natural user interface in response to recognition of the registration phase. The GUI element includes a visual or audio operation cue to prompt the user to carry out the operation phase of the gesture input, and a selector manipulatable by the user via the operation phase of the gesture.
