Exploring Variability of Visual Accessibility Options in Operating Systems

Digital technologies are an opportunity to overcome disabilities, provided that accessibility is ensured. In this paper, we focus on visual and the way it supported in Operating Systems (OS). The significant variability support has practical consequences, e.g., difficulty recommend or select OS, migrate from one OS another. This suggests building a model for would classify them serve as reference. We propose methodology build such with help of Formal Concept Analysis (FCA) framework. addition, can be divided into several concerns (e.g., zoom, contrast), leverage extension FCA, namely Relational Analysis. also ontology dispose standardized description options. apply our proposal analysis few representative operating systems.
