• Adapting data table to improve web accessibility

  Pauli P. Y. Lai · 2013 · Proceedings of the 10th International Cross-Disciplinary Conference on Web Accessibility (W4A)

  This paper addresses the challenge of making web data tables accessible to screen reader users, particularly when tables are not properly marked up with semantic HTML tags like <th>, <thead>, and <tfoot>. Screen readers present content linearly, so large tables become…

• Experiential Transcoding: An EyeTracking Approach

  Yeliz Yesilada, Simon Harper, Sukru Eraslan · 2013 · Proceedings of the 10th International Cross-Disciplinary Conference on Web Accessibility (W4A)

  This paper introduces "experiential transcoding" — a user-centred approach to web page transformation that uses eye-tracking data from sighted users to understand how people actually experience web pages, then uses those patterns to guide transcoding for blind and situationally…

• What Health Topics Older Adults Want to Track: A Participatory Design Study

  Jennifer L. Davidson, Carlos Jensen · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '13)

  This paper presents a participatory design study investigating what health topics older adults (aged 65+) want to track using mobile health (mHealth) applications. The authors argue that most mHealth app developers fail to conduct needs assessments with older adult end users,…

• Follow That Sound: Using Sonification and Corrective Verbal Feedback to Teach Touchscreen Gestures

  Uran Oh, Shaun K. Kane, Leah Findlater · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '13)

  This paper proposes and evaluates two techniques for teaching touchscreen gestures to users with visual impairments: gesture sonification (mapping finger position to audio using pitch for the y-axis and stereo panning for the x-axis) and corrective verbal feedback…

• The Feasibility of Eyes-Free Touchscreen Keyboard Typing

  Keith Vertanen, Haythem Memmi, Per Ola Kristensson · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This poster paper proposes a novel approach to eyes-free touchscreen typing where users imagine a QWERTY keyboard somewhere on the device and tap out an entire sentence without seeing the keyboard and without receiving any intermediate feedback about letters or words typed. This…
