- Urdu keyboard
The Urdu keyboard is any
keyboard layout for anUrdu computer andtypewriter keyboard s. Since the first Urdutypewriter was made available in 1911, the layout has gone through various phases of evolution.Zia (1999a)] With time, the variety of layouts introduced in the 1950s for mechanised compositions have reduced to very few that are compatible with the new digital age. Modern improvements in Urdu keyboard were pioneered by theNational Language Authority ("Muqtadra Qaumi Zaban") inPakistan , which standardised the linguistic aspects such asorthography andlexicography . These developments helped the keyboard layout to evolve from thetypewriter s to be compatible withcomputer s, to increase theproductivity and textual efficiency of the language, especially through modernelectronic media .Evolution of the Urdu keyboard
Urdu is a versatile
language with the potential to expand and grow to fulfil the needs of modern communications technologies. When it was declared as thenational language of the independent Pakistan in 1947, a variety of keyboard designs were quickly brought into the market by various individuals and organisations. [Dil (1962)] However, differences remained in the order of the keys and the number of characters. This underscored an urgent need for a standard form of keyboard adaptable for diverse users..First generation
In 1963, the newly established Central Language Board in Pakistan standardardised the typewriter keyboard. The new standard keyboard also incorporated special characters of other provincial languages, such as Sindhi and Pushto. Languages spoken in Punjab and Balochistan could be easily accommodated within the Urdu characters.
Second generation
The keyboard was again modified in 1974. This time the layout was based on the frequency tables and bifurcation (balancing load on typist's fingers) techniques, and the characters relating to other languages were replaced with the
numeral s.Third generation
In 1980, the National Language Authority of Pakistan developed a new keyboard layout for typewriters based on Naskh script. The keyboard had 46 keys to type 71 Urdu
consonant s,vowel s,diacritic s, andpunctuation marks, and 21 key symbols forarithmetic calculations and digits. However, with the arrival of the digital age, the layout became inadequate for computerised processing that requiredsoftware [Afzal (1997)] backup to select the shape of the character appropriate to the context, and the ability to store multiple language character sets [Zia (1996)] . These issues were addressed through the standardisation of keyboard [Zia (1999b)] for a bilingualteleprinter to use both English and Urdu. The new layout was found appropriate for use in computer-based applications and was immediately adopted with modifications forword processor s.Fourth generation
In 1998 National Language Authority, under Dr.
Attash Durrani 's supervision started working on a research and development project to standardise the Urdu encoding. This resulted in the formation of "Urdu Zabta Takhti" (اردو ضابطہ تختی) (UZT). In July 2000, UZT 1.01 was standardised for all kinds of electronic computing, communications, and storage. [Afzal and Hussain (2002)] Based on this version, Urdu language support was incorporated into the Versions 3.1 and 4.0 ofUnicode . The Keyboard version 1 was finalized by NLA on Dec.14 , 1999 .In 2001, theNational Database and Registration Authority of Pakistan fully adopted this keyboard for Data Entry operations of the Computerised National Identity Cards.Microsoft included this keyboard along with Urdu Language Locale in itsWindows XP operating system forpersonal computer s. [ [http://www.microsoft.com/middleeast/arabicdev/urdu/urdu_support.aspx Urdu language support] at [http://www.microsoft.com Microsoft website] . Retrieved on3 June 2008 .] This keyboard is now standard for the Urdu language. Developments in earlier part of 2008, led to the introduction of the 'ghost character theory' at the NLA, which allows for computerised orthographic representation ofPerso-Arabic script . This enables wider scope of editing with the option of switching between the languages such as Arabic, Balochi, Pashto, Persian, Punjabi, and Sindhi respectively. [Parekh, R. (2008).
