The main purpose of this essay is to build a taxonomy of screens, inspired by Michel Callon’s and Bruno Latour’s Actor-Network Theory. Five fields are considered. Importing a model from the field of epistemology (1) screens will be seen as lenses; importing a model from the field of fictional narratives (2) screens will be seen as doors; importing a model from the field of art (3) screens will be seen as picture-hanging systems; importing a model from the field of reading (4) screens will be seen as tablets; importing a model from the field of leisure (5) screens will be seen as toys. Combination of two, three, four or even five categories is possible, depending from the “situation” in Erving Goffman’s meaning, i.e., the encounter of a technical apparatus, of a kind of image and of a type of gaze.
