Qu'est-ce qu'une surface d'affichage?: une analyse rétrospective

The use of display surfaces, that is windows as well as monitors or projection surfaces, is growing in diversity and complexity. Designers and programmers need a conceptual model of display surfaces to describe this diversity. We show how the conceptual models of windows and monitors have evolved during the last decades up to the current situation where the two concepts are converging. We analyse this evolution along three axes that provide the basic requirements for a unified model: the geometrical attributes of surfaces, their relationships with other display elements, and their position in space.
