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).
Ally creates alternative files that are easier to use by all students. Ally works within your online course so it’s available right where you need it. Alternative files include readable text for screen readers, pictures with captions, and easy-to-navigate content. Ally creates multiple alternatives from the original documents in your course. You can download these alternative formats anywhere that files are used.
