  • Personalized Assistive Web for Improving Mobile Web Browsing and Accessibility for Visually Impaired Users

    Dongsong Zhang, Lina Zhou, Judith O. Uchidiuno, Isil Y. Kilic · 2017 · ACM Transactions on Accessible Computing

    This paper addresses a critical gap in mobile web accessibility: while screen readers enable blind users to access web content, they do not effectively support skimming—the ability to quickly scan content to find relevant information. The authors propose PAW (Personalized…

  • An Analysis of Age, Technology Usage, and Cognitive Characteristics Within Information Retrieval Tasks

    Michael Crabb, Vicki L. Hanson · 2016 · ACM Transactions on Accessible Computing (TACCESS)

    This paper challenges the common practice of using chronological age as the primary metric for distinguishing user performance in HCI studies, arguing that Internet confidence and cognitive factors — particularly perceptual speed — are far better predictors of browsing…
