Resumen
Descripción
La usabilidad se ha convertido en un aspecto fundamental en el desarrollo de un producto software por ser un atributo primordial de la calidad. Este concepto está ligado al carácter de uso del software y puede ser evaluado a través de una prueba de usabilidad. Dicha evaluación, se realiza de manera cuantitativa mediante métricas para dos de los atributos (eficacia y eficiencia) que la definen. La satisfacción como tercer atributo asociado es de carácter cualitativo, cuya estimación es subjetiva, pues depende de la ausencia de incomodidad del usuario de prueba durante la interacción con el producto. Este artículo es resultado de una investigación que postula una propuesta para la estimación de la satisfacción en test de usuarios, teniendo en cuenta el análisis de la expresión facial. Esta idea está soportada en el desarrollo de un sistema software para el seguimiento emocional de un usuario durante una prueba.
Usability has become a fundamental aspect of the development of a software product for being a primordial feature of quality. This concept is linked to the use nature of software and can be evaluated through ausability test. This testing is made quantitatively through measurement for two of the features (efficacy and efficiency) that define it. The satisfaction as a third associated feature is of a qualitative kind which estimation is subjective given that it depends on the absence of discomfort by the test user during its interaction with the product. This article is the result of a research that proposes an approach for the estimation of the satisfaction in user tests involving facial expression analysis. This idea is supported in the development of a software system for the emotional monitoring of a user during a test.
