Teaching materials presented as film or video are likely to present difficulties for blind and visually impaired students. There are two main ways to make them more accessible.
The Scottish Sensory Centre has produced a useful resource on making video more accessible to visually impaired learners.
Deaf and hard of hearing students require transcriptions or subtitled videos for the content to be accessible.
Ensure that any off air recordings that you make to support your course use a VCR that can record embedded subtitles. If you are using bought videos try to ensure that they have embedded subtitles and use a caption decoder. Films on DVD usually have a subtitle option.
Subtitles or transcriptions are needed for these materials to be accessible to deaf students. Make a transcript available for the BSL interpreter or lipspeaker prior to the viewing to give them time to prepare.
