This research addresses the need for a dyslexia-friendly Arabic typeface, responding to a gap in Arabic-language resources for dyslexic readers. While dyslexia-friendly typefaces have been developed for Latin-based languages, the scarcity of equivalent Arabic typefaces reveals a typographic and educational imbalance in dyslexia support. Utilising a user-centred design methodology guided by Maag’s Accessible Type principles, this thesis introduces and evaluates the Mubassat typeface, a dyslexia-friendly Arabic typeface tailored for improved readability among dyslexic readers. Through three empirical studies, the research identifies core visual characteristics that enhance legibility for dyslexic readers, adapts these characteristics into Arabic letterforms, and assesses the typeface's efficacy using subjective and objective evaluations. Findings indicate that Mubassat improves dyslexic readers’ reading speed and accuracy, contributing to the development of accessible educational resources. Beyond type design, this research advocates for greater dyslexia awareness within Arabic-speaking regions, promoting typographic inclusivity and systemic change in Arabic education. The outcomes underscore the importance of culturally adaptive design in addressing neurodivergent needs, offering a pioneering model for future accessible Arabic typography.
