Graphical information is very important in common information publishing. For visually impaired users this information is usually not accessible. Scalable Vector Graphics, a recommendation of the World Wide Web Consortium, describes graphical information in an XML document. We propose a transformation scheme into a tactile representation for this kind of graphics. Navigation modes, filters, and the output of meta information support the exploration of the graphics. Furthermore our software environment can simulate this transformation for all sizes of tactile devices. 1 Motivation Nowadays it is common to have bitmap graphics on web pages.
