Graphical Structure Semantic Markup Languages (GraSSML) aims at defining high-level diagram description languages which capture the structure and the semantics of a diagram from which accessible and "smart" presentations can be generated in different modalities such as tactile, speech, text, graphic, etc.
Many methods making use of alternative presentation techniques (e.g. audio/tactile) have previously been explored. Although these approaches have been shown to partially address the accessibility problem of graphics, they still have limitations mainly due to the absence of information “behind” the graphical representation which is lost at the creation stage.
GraSSML makes the information of the diagram explicit at the creation stage. This opens up new possibilities for allowing Web Graphics to become accessible and "smart" as they carry their knowledge with them.
A proof-of-concept implementation and an evaluation of the approach will be described. We will then discuss how tactile diagrams presented on touch tablet (e.g. IVEO, T3) could benefice from the GraSSML approach.
