A method for sharing, by a secondary machine, an interactive region of a predefined application, executed on a primary machine to which the secondary machine is connected by a physical communications network, including learning a behavior, defining at the primary machine an interactive region to be shared, the interactive region being created within the application and not covering all of the application, exporting at the primary machine the interactive region to be shared to at least one secondary machine, and reproducing an interactive reflection of the interactive region on a secondary machine, the behavior of the interactive reflection being identical to that of the defined and exported interactive region such that identical inputs produce identical results.
