Vinux is a Ubuntu derived distribution optimised for the needs of blind and partially sighted users. By default Vinux provides two screen-readers, Braille display support and a friendly community.
When you boot the live Vinux image, you will be greeted by the Orca screen reader enabling you to navigate the graphical Gnome desktop using keyboard commands. Finally, Brltty provides Grade 1 and 2 Braille output via Orca.
