DAISY, the best way to author sign language publications

There is no standard electronic publication format for sign languages besides ad hoc video media such as the DVD. Sign language requires the structuring and navigational capabilities of DAISY, adapted to both video modalities and visual languages. This paper investigates how video playback can be introduced in DAISY by building on the DAISY 3 standard and on existing open-source software. The paper presents the process of creating and authoring a video-based sign language DAISY publication to serve as test cases. Additionally, the Ability Based Technical Intervention prototype demonstrates how content can be further adapted to users' abilities, learning style and literacy levels to make all-inclusive videobased publications.
