Evidence and Research Needed

rachaelbradley edited this page Mar 12, 2025 · 3 revisions

Overview

The Accessibility Guidelines Working Group (AG) has identified requirements where we need additional research or evidence to include the requirement WCAG 3.

The types of research or evidence we are looking for includes:

  • Academic Research
  • User Studies such as interviews, surveys, usability studies, etc.
  • Requirements for Assistive Technology (AT) to better support people with disabilities or better work with user agents.

Research or evidence must provide transparent information on the methodology used and results. We prefer information that we can publicly reference.

Sometimes research may have been conducted but we haven't been able to locate it. Sometimes new research is needed.

Research Needed

Color Contrast Algorithm Support

Research Questions

  • What color combinations (and at what font sizes) best support reading on modern digital displays, particularly for users with visual and cognitive disabilities?
  • What color combinations best support distinguishing between elements on modern digital displays, particularly for users with visual disabilities?
  • Based on proven color combinations, what existing or possible algorithms support people with visual and cognitive disabilities?

Line Spacing

Research Questions

  • What line spacing best supports reading and comprehension for people with visual or cognitive disabiliites in non-Roman alphabets (particularly vertical written languages)?
