Website Accessibility Metrics: Introduction to the Special Thematic Session

摘要

In many situations it is useful to measure the level of accessibility of websites using a more continual scale rather than the rather limited set of four ordinal values (none, A, AA, and AAA) proposed by the W3C/WAI Web Content Accessibility Guidelines (WCAG). For example, a continual scale allows more granular benchmarking of websites to compare them or to help assess improvements made over time. However, finding reliable metrics is a non-trivial challenge for a variety of reasons. This paper introduces a Special Thematic Session to explore this challenge, further to a previously held online symposium of the W3C/WAI Research and Development Working Group (RDWG).
