Visually Impaired Employees : Articulate 360

Hi All, does someone have any recommendations: We develop courseware in Articulate 360, including drag and drop question types, as well as sliders.

It appears that these are not navigable using a screen reader like JAWS ?

What is the best substitute to allow for the ineractivity of a drag and drop question, and still allow visually impaired participants to complete the training ?

Thanks

Graham
