Designing Documentation for Visually-Impaired Users  

Preparing 'large-print' texts requires more than changing type size; it involves writing and structuring materials to meet the needs of an audience with varied physical challenges. For large print documents, format considerations include: using appropriate type, line length, and other design elements; setting all material flush left; and using lay-flat bindings. For braille documents, text may also need to eliminate or explain unusual symbols. Content considerations for both may include: replacement of graphics with descriptive text: brief orientation to the physical location and dimensions of objects; and reminders of help services. Cassette tapes offer one alternative to print or braille texts, plus serve other audiences.
