Método para la construcción de interfaces de usuario táctiles con mecanismos de accesibilidad mediante técnicas de desarrollo dirigido por modelos

Abstract

Over the years, the use of technology has increased and has become essential in everyday life. Consequently, most of the world's population has become a software user at some point. Many of these users are part of the population that has accessibility problems, that is, some type of sensory, motor, or cognitive impairment that restricts their ability to perform activities of daily living. Thus, the user interface is the main way of interaction between users and the software, this interaction is carried out through various devices. However, currently, the use of touch screens has increased significantly so that they have become ubiquitous in industrial, commercial, and consumer applications. Taking this information into account, it is important to prioritize accessibility aspects in the development of touch user interfaces, seeking solutions that allow adapting the wide variety of accessibility problems that may arise, without wasting time and resources in the development of the interfaces. This work proposes a method for the creation of touch interfaces using accessibility mechanisms through model-driven development (MDD) techniques. This method, which has been called MBAUI, allows using MDD to solve the creation of touch interfaces, taking into account the variations and combinations between accessibility criteria that can be obtained by analyzing the degree and types of impairments of the users. Finally, the method is empirically validated through the execution of a quasiexperiment. This quasi-experiment assesses the user's perception of performing various tasks after a training session
