Blackboard Ultra does provide a service within it called Ally. This service works in the background and will ‘convert’ files uploaded to Blackboard into multiple alternative formats. This means that students can choose formats that work best for them (e.g. HTML for improved reading on mobile phones, electronic braille for the visually impaired, and audio for learning on the go or for those who find reading difficult).
It is good inclusive practice for documents and other files to be designed and produced with some basic accessibility principles in mind. In addition, however, for Ally to undertake its work effectively, it is vital that the files uploaded originally are designed with basic accessibility principles applied. For example, if you upload a Word document with some images in, but the images have no ‘alt’ descriptions, then Ally will not be able to produce an audio version of that document that can provide a spoken description of that image at the point that the image appears.
