Making an animation accessible (Option)
It seems like an impossible mission to adapt all the interactive possibilities of a Fluidbook to the visually impaired. Our solution is to provide alternative content only presented to this audience. Images, illustrations, animations etc., are replaced by Text-to-Speech descriptions. You can substitute all the content of a page with adapted and well-organized text to be read by the fluidbook or screen reader. Why not add a welcome message when the fluidbook is opened?
Some content like charts or complex illustrations can be hard to describe by text. An excellent solution to this problem is to use the fluidbook zoom areas (more info). When clicked, these areas expanded to fill the whole screen and drastically increase the readability.
