Accessible graphics in web applications: dynamic generation, analysis and verification

Abstract

Accessibility for graphics in web applications is still not only a shortcoming for visually impaired people but may also be a request of people with other special needs. In the Access2Graphics project SVG (Scalable Vector Graphics) is used to dynamically generate graphics that are adapted to the user's individual requirements in order to make them accessible for each user. Beside the users also the graphics designer (provider) need support to be able to offer accessible graphics. The focus of this paper therefore mainly is on introducing the analysis as well as the verification component of Access2Graphics. Both, reuse of existing graphics and verification with respect to defined guidelines should make the generation process of graphics more efficient regarding the development time and quality. © 2008 Springer-Verlag Berlin Heidelberg.
