Abstract

Since the late Eighties, technological change and transition from analog to digital, led to a challenging of the classical categories of modernist design. With the development of Human Computer Interaction and its impact on theories of Functionalist Design, it has begun a process of interrogation – initially in a cognitive sense and then in the more properly aesthetic sense – which, through theories and practices increasingly dependent on computerization , brings modernist theories about functionality to shift their interest on Usability and, then, from Usability to User Experience
