Abstract

Testing accessibility of a web site is still an art. Lack of appropriate definitions of accessibility and of standard testing methods are some of the reasons why Web accessibility is so difficult to achieve.

The paper describes a heuristic walkthrough method based on barriers; it then discusses how methods like this can be evaluated, and it shows experimental data about validity and usefulness of the method when compared to standards review.
