—The graphical user interface (GUI) of an interactive system is nowadays the most frequently used interaction modality. While the contents are of high importance, the Look and Feel is an equally essential factor determining the GUI quality that is impacted by several determinants such as but not limited to aesthetics, pleasurability, fun, etc. Therefore, GUIs aesthetics is a potential element to focus on in order to facilitate communication between device and user. On that basis, one question that comes up is: “Is it possible to evaluate the quality of a GUI by estimating its aesthetics through a series of measurable geometric metrics?”. This paper suggests possible directions to address the previous question by, ﬁrst, introducing a simplifying model of GUIs aesthetics that captures aesthetics aspects and regions-related metrics. In a second phase, a methodology for the evaluation of GUIs aesthetics is deﬁned based on the underlying model. The paper ﬁnally puts forwards a model-based implementation of the aforementioned methodology in the form of a web service tool for metric-based evaluation of GUIs and discuss the results of a survey on users aesthetics perceptions.
