• Adee: Bringing Accessibility Right Inside Design Tools

  Samine Hadadi · 2021 · The 23rd International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2021)

  This extended abstract introduces Adee, an accessibility testing plugin that integrates directly into popular design platforms — Adobe XD, Figma, and Sketch — to make accessibility checking a seamless part of the design workflow rather than an afterthought. The paper argues that…

• Analysis of automated contrast checking tools

  Rafael Almeida, Carlos Duarte · 2020 · Proceedings of the 17th International Web for All Conference (W4A)

  This paper evaluates the reliability and limitations of three free automated color contrast checking tools: the Color Contrast Accessibility Validator (from the Bureau of Internet Accessibility), WAVE (from WebAIM), and the WCAG Color Contrast Checker (a browser extension for…

• Still Not Readable? An Interactive Tool for Recommending Color Pairs with Sufficient Contrast based on Existing Visual Designs

  Fredrik Hansen, Josef Jan Krivan, Frode Eika Sandnes · 2019 · Proceedings of the 21st International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2019)

  This demonstration paper presents a web-based color contrast tool that goes beyond the pass/fail validation of existing contrast checkers by actively recommending how to fix insufficient color contrast while preserving the designer's original visual intent. The authors observe…

• Good Background Colors for Readers: A Study of People with and without Dyslexia

  Luz Rello, Jeffrey P. Bigham · 2017 · Proceedings of the 19th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '17)

  This paper presents the first large-scale user study measuring the effect of background colors on screen readability for people with and without dyslexia, providing empirical evidence for the widely recommended but previously unvalidated practice of using colored backgrounds to…

• Real-Time Mobile Personalized Simulations of Impaired Colour Vision

  Rhouri MacAlpine, David R. Flatla · 2016 · Proceedings of the 18th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '16)

  This paper extends personalized simulations of Impaired Colour Vision (ICV) to work in real time on mobile devices, enabling people with typical colour vision to see the world through the camera as someone with ICV would perceive it. At least 5% of the world population has some…

• Reconciling User and Designer Preferences in Adapting Web Pages for People with Low Vision

  Yoann Bonavero, Marianne Huchard, Michel Meynard · 2015 · Proceedings of the 12th International Web for All Conference (W4A)

  This paper addresses the challenge of adapting web pages for people with low vision while preserving the original design intent. Unlike simple approaches that override all colors or apply uniform changes, the authors frame web page adaptation as a multi-objective optimization…

• Layout Guidelines for Web Text and a Web Service to Improve Accessibility for Dyslexics

  Luz Rello, Gaurang Kanvinde, Ricardo Baeza-Yates · 2012 · Proceedings of the International Cross-Disciplinary Conference on Web Accessibility (W4A)

  This paper presents evidence-based layout guidelines for making web text more readable for people with dyslexia, derived from a user study with 22 dyslexic participants and a matched control group. The study is notable for being the first to combine eye-tracking data with…

• Accessible Icon Design in Enterprise Applications

  Eric Stilan, Amy Chen, Lulit Bezuayehu · 2011 · Proceedings of the International Cross-Disciplinary Conference on Web Accessibility (W4A)

  This paper from Oracle's design team presents case studies of designing accessible icons for enterprise software, focusing on the challenge of conveying complex meanings — conditional status, severity levels, data trends — within 16x16 pixel icons without relying on color as the…

• Accommodating Color Blind Computer Users

  Luke Jefferson, Richard Harvey · 2006 · Proceedings of the 8th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '06)

  This paper from the University of East Anglia presents an algorithm for recoloring digital images and documents so that color information is preserved for color blind viewers, particularly dichromats (people missing one type of cone cell). The algorithm addresses a fundamental…

• SmartColor: Disambiguation Framework for the Colorblind

  Ken Wakita, Kenta Shimamura · 2005 · Proceedings of the 7th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '05)

  This paper presents SmartColor, a framework that automatically repaints coloured documents so that people with colour vision deficiencies can perceive the same colour effects — such as contrast, shared colour grouping, and distinguishability — that the original author intended…

• The User Experience: Designs and Adaptations

  Vicki L. Hanson · 2004 · Proceedings of the 2004 International Cross-Disciplinary Workshop on Web Accessibility (W4A)

  This keynote-style paper from IBM's Watson Research Center by Vicki Hanson argues that web accessibility standards and guidelines, while necessary, do not guarantee a usable or satisfying experience for people with disabilities. The paper distinguishes between accessibility…
