Improving Accessibility and Usability of Geo-referenced Statistical Data

Several technology breakthroughs are needed to achieve the goals of universal accessibility and usability. These goals are especially challenging in the case of geo-referenced statistical data that many U.S. government agencies supply. We present technical and user-interface design challenges in accommodating users with low-end technology (slow network connection and low-end machine) and users who are blind or vision-impaired. Our solutions are presented and future work is discussed. (UMIACS-TR-2003-37) (HCIL-2003-11)
