Propuesta de modelo para perfilamiento de usuarios de e-Learning con consideraciones de Accesibilidad

Abstract

In this study, a model for the generation of profiles of users with disabilities is proposed. This model allows e-Learning platforms to have information on the accessibility needs of users as an input for the automated adaptation of their interfaces. This would allow equitable access for all students with and without disabilities. In this context, different studies related to the creation of user profiles on e-Learning platforms were identified and analyzed. The presented model considers the Web Content Accessibility Guidelines (WCAG) that can be implemented in the interfaces of e-Learning platforms and the metadata that represent the accessibility needs of users based on Schema.org. The prototype testing was carried out using WAVE and the ARC Toolkit. The validation with the support of forty-four users was carried out using the System Usability Scale (SUS). The most prominent results of this study are the identification of the WCAG success criteria that can be implemented automatically, the inclusion of two special categories for the combined accessibility needs related to the elderly and linguistics, and the automatic generation of the profile as an XML file that contains the metadata.
