Leporini B., Andronico P., Buzzi M., Castillo C. Evaluating a modified Google user interface via screen reader. In: Universal Access in the Information Society, vol. 7 (3) pp. 155 - 175. Springer, 2008.
This paper describes the progress of a research project aimed at improving the usability of web search tools for blind users who interact via screen readers and voice synthesizers. In the first stage of research, specific guidelines were proposed for simplifying the interaction with search engines for the blind. To evaluate these criteria, they were applied to Google user interfaces, by re-implementing the search form as well as the results page. Finally, the redesigned interfaces were evaluated through remote testing with 12 totally blind users. The results highlighted how Google, although already accessible, may be further improved in order to simplify interaction for people with impaired vision.
