Towards the Improvement of W3c Web Content Accessibility Guidelines

This paper presents the results of a study about possible improvements to the ISO 40500 standard, which contains the web content accessibility guidelines established by the World Wide Web Consortium in WCAG 2.0. Expert web developers from twelve different countries have participated in the study. In order to ensure the objectivity of the results, the experts interviewed were unrelated to each other’s. Interesting coincidences in opinions have been found, especially those relating to changing the levels of conformance of some success criteria established by WCAG 2.0. Suggestions about possible improvements were collected, such as modifying the existing criteria or including new ones. The study shows that, in the opinion of the experts, there are still some aspects of the standard that could be improved.
