Vinux allows blind and visually impaired computer users to install a version of Ubuntu independently. It includes Orca (a screen reader and magnifier), Speakup (a console screen reader), Compiz (a magnifier based on 3d technology), and support for Braille displays. Braille displays operate automatically when connected and support grade 1 and 2 Braille. Vinux can run from a live cd or Live USB without making any changes to a current operating system. It can be installed to a USB or hard drive alongside a current operating system or as a complete replacement.
