Explaining Accessibility: Possible Variables in Users’ Abilities, Tasks, and Contexts in IT Artefact Use
Year: 2023
Type: article
Abstract: The interconnection between the two information technology (IT) artefact qualities, accessibility and usability, is challenging to define. Efforts to design and develop accessible IT artefacts should encompass the broadest range of user abilities in identified tasks and contexts. We lack sufficient research on information systems and human-computer interactions that presents a comprehensive model to explain what variables these key components of accessibility contain and how they interconnect. To address this gap in the literature, I draw on theories beyond human-computer interactions, tasks, and contexts to posit the influence of human abilities on IT use by referring to the International Classification of Functioning, Disability, and Health (ICF) framework that the World Health Organization developed. In this paper, I theoretically describe accessibility, its components, and their relationships in the IT use context based on which I present an accessibility model. Furthermore, I argue that accessibility is a moderating variable between system features and usability. Therefore, accessibility is a major determinant of user acceptance.
