document: Accessibility : a Web engineering approach Currently , the vast majority of web sites do not support accessibility for visually impaired users . Usually , these users have to rely on screen readers : applications that sequentially read the content of a web page in audio . Unfortunately , screen readers are not able to detect the meaning of the different page objects , and thus the implicit semantic knowledge conveyed in the presentation of the page is lost . One approach described in literature to tackle this problem , is the Dante approach , which allows semantic annotation of web pages to provide screen readers with extra ( semantic ) knowledge to better facilitate the audio presentation of a web page . Until now , such annotations were done manually , and failed for dynamic pages . In this paper , we combine the Dante approach with a web design method , WSDM , to fully automate the generation of the semantic annotation for visually impaired users . To do so , the semantic knowledge gathered during the design process is exploited , and the annotations are generated as a by-product of the design process , requiring no extra effort from the designer .
