“…The test applied to the students consists of a pre-test questionnaire and a post-test questionnaire, which are carried out before and after the interaction with the video game, the above taking into account the conventional usability tests developed in a usability laboratory [9][10][11][12]. The pre-test questionnaire is given to the students at the beginning of the test and consists of a set of 5 single-choice questions (yes/no) related to the previous knowledge of the subject matter addressed by the serious video game.…”

“…One of the most effective ways to evaluate the usability of a software product is through the so-called user tests, in which a set of users perform tasks in a controlled environment or usability laboratory, which are supervised by a set of evaluators in order to determine the attributes that define usability, where the attributes defined by ISO 9241-11 (effectiveness, efficiency and satisfaction) are usually the most widespread [6,7]. In a conventional user test developed in a usability laboratory, effectiveness can be determined from the percentage of tasks completed by the users, efficiency can be obtained by relating the time spent by each user in performing a task with respect to the time estimated by the evaluator, while satisfaction is determined in the traditional way through the use of so-called perception surveys [1,10].…”

With the growth in the number of applications deployed in cloud app stores, usability has become a fundamental attribute to ensure end-user productivity and enterprise competitiveness. According to ISO 9241-11, the three attributes that determine the usability of a product are effectiveness, efficiency and satisfaction, the latter being the subjective attribute of usability. In conventional user tests, the satisfaction attribute is determined using perception questionnaires, being a challenge to determine this attribute more objectively, given the limitations of surveys in terms of veracity and subjectivity. Based on the above, in this article we propose as a contribution, the construction of a system based on fuzzy logic for the estimation of the usability satisfaction attribute in user tests, which has as inputs both the level of satisfaction obtained from the answers to the post-test questionnaire, and the level of satisfaction obtained from the polarities of the opinions of the test users, determined by means of sentiment analysis techniques. The proposed fuzzy system is intended to serve as a reference to be replicated at the academic and enterprise level in the conduct of usability tests and specifically in the more objective determination of the satisfaction attribute based on the advantages of fuzzy logic and sentiment analysis techniques.

Uno de los factores clave que contribuye con la mejora del posicionamiento de los portales web empresariales es la accesibilidad, teniendo en cuenta la gran cantidad de usuarios y el volumen de contenidos disponibles en la Web. La accesibilidad posibilita que los motores de búsqueda den prioridad a aquellos portales que han incorporado dichas características. El objetivo de este artículo es proponer un conjunto de recomendaciones de accesibilidad para mejorar el posicionamiento de portales web empresariales, las cuales fueron determinadas a partir de pautas y niveles de conformidad de la norma de accesibilidad colombiana NTC 5854. Para el desarrollo metodológico de esta investigación, se usaron las cuatro fases del patrón iterativo de investigación propuesto por Pratt: observar, identificar, desarrollar y probar. Estas permitieron definir las recomendaciones y verificar su pertinencia en una inspecciones de accesibilidad. Como resultado principal se obtuvo un conjunto de recomendaciones para el diseño accesible de portales web, enfocadas en mejorar el posicionamiento de estos sitios y agrupadas de acuerdo con los cuatro principios de la norma NTC 5854. Asimismo, se desarrolló una herramienta automatizada que permite la conducción de inspecciones de accesibilidad en portales web haciendo uso de las recomendaciones definidas. A modo de conclusión, la inspección desarrollada sobre el portal web Janus con la herramienta construida permitió verificar la pertinencia de las recomendaciones, de cara a posibilitar que un mayor número de usuarios puedan acceder, percibir, operar y comprender el contenido de la Web.
