The system includes a control unit for ascertaining a position of the virtual tip based on the captured position and alignment of the real component and for arranging for the image output unit to display, with a mark, the position of the virtual tip in the displayed captured portion of the object. An operating method, a pointer device suitable as a real component and a computer program product are provided.
