Research Abstract

This research consists of two parts : 1. A Development of an Optical character recognition system for materials in print including mathematical expressions and 2. A development of acomputerized aloud-reading system for results obtained by OCR.We have achieved the following through the research, respectively.
1. The method to separate mathematical expressions from scanned images is investigated. We give several new procedures concerning precise recognition of mathematical expressions. Furthermore, we develop a utility to output results of OCR as a variety of file formats ; for instance, LaTeX.User interfaces for persons with visual disabilities are also prepared.
2. We develop a speaking macro for a generally used editor on Microsoft Windows in Japan. It analyzes LaTeX files and read aloud mathematical expressions in Japanese, using a generally used screen reader. We have performed several evaluations and improved this macro. The newest model works for scientific and technical materials of rather high level. Combining these two techniques, even if students had visually disabilities, they could access technical materials in print.
