39th Annual CSUN Assistive Technology Conference Has Concluded

New Accessibility Platform "Chatty Library"

Date & Time
Thursday, March 21, 2024 - 1:20 PM PDT  
Orange County 1-2  

We have developed "Chatty Library" under the Nippon Foundation’s subsidy that is contributed to welfare-aimed innovative projects. This new accessibility platform is a web site that provides you with not only daisy books (we refer to Multimedia DAISY and Accessible EPUB3 all together as daisy books) themselves but also a variety of other innovative services related to them: playing them back with a popular browser, converting PDF into a daisy book automatically, sharing information on them, etc.

To realize automatic conversion, we have proposed a new type of daisy books, "Fixed-Layout DAISY." In it, the whole page is treated as a multi-layer picture, the front layer of which has the same form as the original PDF. A DAISY (EPUB3) player can read out any texts together with highlighting them. It does not have the reflow function. The page layout is always kept as same as the original. It does not have information either in which order texts blocks on the page should be read out, and readers need to click a text block on a page where they want to read. Dyslexic people can see and click a place where they want to read, and obviously, Fixed-Layout DAISY should work for them. Fixed-Layout DAISY can be produced almost automatically from an original "e-born PDF" with the AI-based conversion service in Chatty Library, and it should be very helpful for the dyslexic students to get accessible version of their textbooks.
