Development of a Nemeth Math to Latex Backtranslator System

The project extends and enhances the prototype developed in Phase 1 to obtain a reliable, robust, and complete software environment for backtranslating mathematical documents (containing mathematical expressions coded in Nemeth Math code and regular text coded in ASCII Grade 2 Braille) to Latex. The project is conducting research on: (1) automatic detection and recovery from errors in the Math document encountered using backtranslation; (2) automatic identification of parts of the documents that contain text, mathematics, and spatial arrangements respectively; and (3) allowance for hard copy input via Optical Braille Recognition. The system facilitates students, scientists and engineers with visual impairment to communicate with their signed instructors and colleagues.
