1. Activity

Science Accessibility Net (sAccessNet) is a nonprofit organization whose mission is to, "support students with print disabilities" wishing/needing to learn and excel in STEM (science, technology, engineering and math) disciplines. A person with a print disability cannot effectively read and acquire knowledge from print materials because of a visual, physical, perceptual, developmental, cognitive, or learning disability. Using our software applications (described below) sAccessNet produces K-12 STEM-based e-textbooks in accessible formats. These formats include Braille, ePub3, and multimedia DAISY which is an international standard format for accessible e-books. In addition, we conduct "jump-to-science" summer camps every two years to encourage visually impaired highschool students leaning science, and are making school textbooks / science books in accessible formats in braille and multimedia DAISY: (Japanese site).

2. Software development and release

sAccessNet, in cooperation with the "InftyProject" research group, has been researching1 and developing advanced applications, designed to enable students with print disabilities to accessing STEM content and successfully acquire knowledge from it. These advanced applications are also being used by sighted professionals who support students with print disabilities. Our applications are described below:

1. InftyReader (Latest release: Ver. on Jan. 5, 2022)

"InftyReader" is an Optical Character Recognition (OCR) application that automatically recognizes and translates print, e-born PDF, and Image-based STEM documents (including math symbols) into LaTeX, MathML and XHTML. InftyReader. InftyReader can recognize tables containing math expressions within its cells.  Its recognition results can be output in various accessible formats such as, LaTeX, MathML, IML (Infty-original XML), Human readable TeX in support of students with print disabilities including students who are totally blind. (Japanese version outputs also in Japanese Braille). The output results in IML can be edited using InftyEditor and ChattyInfty below.

The documents written in InftyEditor can be saved in different formats: XML of InftyEditor, LaTeX, MathML, Human Readable TeX for the blinds, PDF, as well as MS Word document. If InftyReader is installed in your PC, you can input texts and math expressions from printed document via scanner into InftyEditor directly.
