Beautiful interfaces. From user experience to user interface design

The paper is aimed to explore and to conduct a critical review of the latest position in the debate of the aesthetic dimension of visual design applied to graphical, multimodal and virtual interfaces in the digital field and its impact on the experience of people. The relationship between form and function -aesthetic values and technical issues-has become the juxtaposition between graphic and usability in the digital field. The mobile revolution in 2007 has forced designers to rethink the interaction and interface concepts, since the introduction of the desktop metaphor in 1984. The skeuomorphism style and the transition to flat patterns are a strong evidence of the ongoing discussion about the visual paradigms adopted. Brutalism start by Deville in 2014 is a deep reaction that recalls to design its role and its own value.
