What is Braille?

Braille is a tactile system of reading and writing made up of raised-dot patterns for letters, numbers and punctuation marks.  This format is used almost exclusively by people with visual impairments.  Braille may be either embossed (a permanent printed document) or refreshable (electronically generated and accessed via a Braille display device).

What is digital text?

Digital text is electronic text that can be delivered via a computer or by another device.  A key accessibility consideration is that digital text is malleable and can be easily transformed in many different ways depending upon student needs and the technology being used for rendering.  To accommodate the needs and preferences of a user, various features of the technology which control how the content is presented to the user can be manipulated such as size, fonts, colors, contrast, highlighting, and text-to-speech, etc.  It can be navigated by unit, chapter, section, and page number.  Images include alternative text and long descriptions when appropriate.  Math equations are provided as images with text descriptions.  Order of content, levels, and headings are appropriately formatted.
