- The Organización Nacional de Ciegos Españoles (ONCE) sells a braille guidebook to Barcelona, provides information about restaurants which have braille menus, and can arrange trips for blind and visually-impaired people. Moreover, in 2003 ONCE has developed a system based on GPS to guide blind people. The system called "Tormes" is a computer with a Braille keyboard and satellite navigation technology that gives verbal directions. They also play host to occasional events.
