Scientific diagrams made easy with IVEO

Virtually all modem scientific documents and textbooks use graphical illustrations and/or data displays. The ViewPlus IVEO technology, based on Scalable Vector Graphics (SVG) is being developed to permit scientists to publish such graphics in a form fully usable by all people. The first release of IVEO was designed to make simple graphics accessible. Development of the second release, which includes improved text accessibility, linking, and interactivity, is described in this paper. We also discuss new research to expand accessibility of quantitative data in IVEO documents by using non-speech audio.
