Ubuntu is based on Linux - the open source operating system and has apparently become the most popular of all the Linux distributions. It is currently used by the French national police force, which runs its operations on the open source OS; computer systems supporting Spanish schools have their own version; the online encyclopaedia runs its hundreds of servers on Ubuntu and SFIA's internal computer system is based around it.

Magnification and speech synthesis

Orca is a screen reader and magnifier that enables users with limited vision, or no vision, to use the Gnome desktop and associated applications. The magnifier features automated focus tracking and full-screen magnification. The screen reader enables low-vision and blind users to access applications via speech and braille output. Key-mapped functions are organised on layers giving control over navigation, mouse, magnifier, speech and Braille devices. Orca can be customised to individual applications. This can make otherwise difficult interfaces, such as those of instant messaging clients, easy to use. Orca is available on the Ubuntu Desktop CD.
