Ferres, Leo, Verkhogliad, Petro, Sumegi, Livia, Boucher, Louis, Lachance, Martin and Lindgaard, Gitte (2008): A syntactic analysis of accessibility to a corpus of statistical graphs. In: Proceedings of the 2008 International Cross-Disciplinary Conference on Web Accessibility W4A 2008. pp. 37-44. Available online

“Designing graphs and charts visually by means of graphing applications such as OpenOffice or MS Excel is extremely efficient and cost-effective. However, one of the drawbacks of such approach is that graphs are sometimes involuntarily made less accessible by, for instance, using a text box as title. In this paper we evaluate a corpus of 120 ecologically-valid statistical graphs for accessibility problems, discuss possible algorithms to solve these problems and finally propose the OM (Object Model) Principle, which states that any digital object is made more accessible by simply using the application's model for that object: for instance, the TITLE field for the title text.”

Thomas, Kavita E., Sumegi, Livia, Ferres, Leo and Sripada, Somayajulu (2008): Enabling access to geo-referenced information: Atlas.txt. In: Proceedings of the 2008 International Cross-Disciplinary Conference on Web Accessibility W4A 2008. pp. 101-104. Available online

“We present Atlas.txt, a novel data-to-text natural language generation system which enables access to geo-referenced information like online census data. We first discuss initial findings from an accessibility study on geo-referenced data and outline needs requirements for visually-impaired users of such data. We then present work towards realising our data-to-text system and indicate how it aims to address this issue.”
