Assistive Technology Research
Project 1: Mathematics Accessible to Visually Impaired Students (MAVIS)
This projects deals with making mathematics, science, and technology
accessible to blind students. A translator is being developed from
Nemeth Math Braille notation (the Braille based notation for marking
up Mathematics for the blind) to Latex. The Nemeth Math Braille notation was
designed in 1951, and is quite complex. Use of denotational
semantics-based techniques as well as logic programming has
allowed us to develop a translator to Latex, a task that is
extremely hard using traditional compiling technology. An equation
editor for blind users is also being developed (that work is headed
by Art Karshmer). The project is funded by NSF.

Project 2: Making WEB Accessible to the Visually Handicapped
Tools are being developed to enable visually impaired users
to navigate the WEB more effectively. In particular, techniques
are being developed for effective navigation of web-pages with
tables, frames, and forms. Other Participants: A. Karshmer,
E. Pontelli, D. Gillan (Psych.). The project is funded by NSF.
