Abstract: The operating method according to the invention is implemented in a computing device comprising a central processing unit, man-machine interface means including a display screen, and an operating system including a graphical user interface. The method comprises an implementation in the graphical user interface of a first metaphor in the form of a zoomable space (E3) appearing on the viewing screen and of a second metaphor in the form of a card (CT1, CT2) contained in the zoomable space, and a display in the cards of graphical representations corresponding to various types of digital objects as a function of a plurality of links between the objects and the cards, the plurality of links being established between the objects and the cards by at least some interactions via the graphical user interface between a user and the operating system.
