Web Accessibility Assessment Through Multi-Agent Support for Visually Impaired Users

摘要

In general, users who access Web sites do not necessarily have the same abilities in terms of cognitive, sensory and physical conditions. An accessible Web site is one whose content can be used by as many users as possible; and to improve accessibility, the use of evaluation tools has been incorporated among other resources. However, from the point of view of the end user, the evaluation obtained by most. of these tools does not fit to the individual needs and abilities of the users. On the other hand, there is a greater understanding of the need to automate the support to reach higher levels of accessibility.
