I wrote a couple of months ago about my colleague Sheryl Burgstahler and her DO-IT projects to help students with all kinds of disabilities work with computing.
Now Sheryl, along with Richard Ladner and Rajesh Rao of the Computer Science department and Melody Ivory-Ndiaye or the Information School have won a big new grant from National Science Foundation to find the best ways to represent in tactile form the graphical images found in scientific, engineering, and mathematical books and papers, as well as in digital formats, and to automate as much of this work as possible.
The project web site is here. Nice work!
