An Accessibility Heuristic Evaluation of Bulgarian and Polish Academic Web Sites: Visually Impaired Users’ Perspective

Accessibility issues are actively involved in the field of information and communication technologies. To improve human-machine interfaces, it is necessary to study the specifics of the interactions of people with special needs, including to improve their security of access to various digital resources. Thanks to the state of the art, people with disabilities have wide access to the Internet, including educational resources. The aim of this paper is to propose an approach for the heuristics evaluation of web accessibility based on the analytic hierarchy process (AHP) method. As there are many groups of people with disabilities, to narrow the scope of this study, we turn our attention to the perspective of the visually impaired users. To approve the approach, the authoring team applies it using Bulgarian and Polish academic websites.
