QUEZADA-BOLANOS, Edna P.  e  GALLARDO-LOPEZ, Lizbeth. TriSigEM: a Semiotic Model for Usability Evaluation of Graphical User Interface in Apps. Zincografía [online]. 2023, vol.7, n.14, pp.5-25.  Epub 01-Dez-2023. ISSN 2448-8437.  https://doi.org/10.32870/zcr.v7i14.204.

The percentage of user acceptance and adoption of some apps needs to be improved. Sometimes the app’s functionalities work correctly, but its GUI does not allow correct use. Our research subject is usability in implementing GUI Design Patterns. This paper describes the design and implement of TriSigEM (Peirce’s Triad of Signs Evaluation Model), a quantitative and hierarchical model that guides evaluators in observing the GUI’s signs: Index, Icon, and Symbol. TriSigEM can help us improve GUI’s implementation and, eventually, the app’s functionalities. Also, this paper presents a comparative analysis of TriSigEM with related works reported in the literature. This analysis shows that TriSigEM surpasses other models and highlights that the analyzed GUI patterns need specifications on the Triad of Signs.
