Vinux is a remastered version of the popular Ubuntu 10.04 Lucid Lynx distribution optimised for the needs of blind and partially sighted users.. It provides three screen readers, two full-screen magnifiers, global font-size and colour changing facilities, and out-of-the-box support for USB Braille displays. The Vinux live CD boots into the Orca screen reader which makes it easy to navigate the graphical GNOME desktop using keybindings. For those who prefer to work in a simple text-based console there is the Speakup screen reader as well as YASR, a hybrid screen reader which can be run in either console mode or in a virtual terminal on the GNOME desktop. The latest version is Vinux3.0 and is based on Ubuntu 10.04 Lucid Lynx.
The reason I put this link up is that I have several visually impaired and blind friends which could benefit from this OS greatly as opposed to using jaws or some other proprietary windows based software and OS distro which can end up costing thousands of dollars…
