Method for Accessibility Assessment of Heading in Online Editors

This paper presents the evaluation results of online content editors TinyMCE and Atto installed on the Moodle 3.3.1 platform with respect to the production of accessible headings. Previous studies have shown that lack of accessibility in headings affects the navigability of people using assistive technologies, as well as people who are slower readers or have short-term memory. The evaluation was carried out applying a model oriented to evaluate the accessibility of heading, images and tables in online editors. This model was developed by the authors of this research considering the compliance of the Authoring Tool Accessibility Guidelines 2.0 (ATAG 2.0), the Web Content Accessibility Guidelines 2.0 (WCAG 2.0), as well as related compliance levels and techniques. The results obtained in this study demonstrate that the evaluated online content editors have a low level of compliance of ATAG 2.0 with respect to the creation of accessible content.
