ABSTRACT
The computers that are now invading our daily life seem to be increasingly trying to emulate human models of communication. This is not just at the level of information representation, from numerical codes of the first forms of human-computer communications to highly iconic figures of actual software interfaces (on the evolution of human-machine interfaces, see Anceschi, 1993), but most of all because these machines have progressively developed the acquired capacities of the perception of sensory data.
