  gnopernicus is a free gnome desktop application that provides assistive technologies (at) for blind and visually impaired users. the development of gnopernicus was led by baum engineering, a partner company of baum retec ag. gnopernicus is a "one-size-fits-all" screen reader that provided speech, braille, and magnification for users with a range of visual impairments. gnopernicus provided for a fair amount of user interface customization - including customizing the speech output and voices, customizing the keystroke commands to drive it, customizing the braille display key input, and customizing the way magnification is rendered. it was also possible to edit the xml files that describe the speech and braille output renderings. gnopernicus was bundled as the default screen reader in gnome 2.4 in september 10, 2003, however, the development of gnopernicus was started in 2001. orca, with its radical different coding approach of making applications accessible, had more flexibility than the original gnopernicus design and replaced it as the default screen reader in gnome 2.16 in september 2006.{{cite news|title= ge
