Further Info

People with very little or no vision, on the other hand, read web pages with the help of access technology installed on their computer. Synthesised speech software can read the content of web pages aloud through a speaker, while braille software can output the same content to a retractable braille display so that the web page can be read by touch. Good design is essential for people accessing the web in these ways - poor design can render a site completely inaccessible.
