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: http://www.saccessnet.com (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:
We release a new set of InftyReader, ChattyInfty and ChattyBooks, freely usable during this Corona Pandemic, to help teachers to make math PDF to accessible content for their students. The free use period is set up to the end of September, 2020. To get the offer packages, please visit here..
