Question: Information:  - Tibetan Braille is the braille alphabet for writing the Tibetan language . It was invented in 1992 by German socialworker Sabriye Tenberken . It is based on German braille , with some extensions from international usage . As in print , the vowel a is not written . Despite Tibetan and Dzonkha ( Bhutanese ) using the same alphabet in print , Tibetan Braille differs significantly from Dzongkha Braille , which is closer to international norms .  - The slate and stylus are tools used by blind persons to write text that they can read without assistance. Invented by Charles Barbier as the tool for writing night writing, the slate and stylus allow for a quick, easy, convenient and constant method of making embossed printing for Braille character encoding. Prior methods of making raised printing for the blind required a movable type printing press.  - A writing system is any conventional method of visually representing verbal communication. While both writing and speech are useful in conveying messages, writing differs in also being a reliable form of information storage and transfer. The processes of encoding and decoding writing systems involve shared understanding between writers and readers of the meaning behind the sets of characters that make up a script. Writing is usually recorded onto a durable medium, such as paper or electronic storage, although non-durable methods may also be used, such as writing on a computer display, in sand, or by skywriting.  - A refreshable braille display or braille terminal is an electro-mechanical device for displaying braille characters, usually by means of round-tipped pins raised through holes in a flat surface. Blind computer users who cannot use a computer monitor can use it to read text output. Speech synthesizers are also commonly used for the same task, and a blind user may switch between the two systems or use both at the same time depending on circumstances. Deafblind computer users may also use refreshable braille displays.  - Sabriye Tenberken (born 1970) is a German socialworker and co-founder of the organisation Braille Without Borders.  - A braille embosser is an impact printer that renders text as tactile braille cells. Using braille translation software, a document can be embossed with relative ease, making braille production efficient and cost-effective.  - Braille is a tactile writing system used by people who are blind or visually impaired. It is traditionally written with embossed paper. Braille-users can read computer screens and other electronic supports thanks to refreshable braille displays. They can write braille with the original slate and stylus or type it on a braille writer, such as a portable braille note-taker, or on a computer that prints with a braille embosser.

Question: Information:  - Citizenship is the status of a person recognized under the custom or law as being a legal member of a sovereign state. A person may have multiple citizenships and a person who does not have citizenship of any state is said to be stateless.  - Australian Americans are Americans who identify with an Australian ancestry .  - Nationality is the legal relationship between a person and a state.
