A Universal Amazigh Keyboard for Latin Script and Tifinagh LES RESSOURCES LANGAGIERES : CONSTRUCTION ET EXPLOITATION A universal Amazigh keyboard for Latin script and Tifinagh Paul Anderson [email protected] 1. Introduction Systems of Amazigh text encoding and corresponding keyboard layouts have tended to be narrowly aimed at specific user communities, because of differences in phonology and orthography across Amazigh language variants1. Keyboard layouts for language variants have therefore lacked orthographic features found in other regions. This restricted focus impedes users' experimentation with the writing of other Amazigh regional variants and converged literary forms where they differ in orthographic features or in script. So far there has been no way to type more than a handful of Amazigh variants intuitively on any one layout even within one script. This fragmented development has meant that keyboard driver implementations have often lagged behind advances in technology, and have usually failed to take into account general keyboard layout design, ergonomy and typing speed, and solutions from other Amazigh regions or non-Amazigh languages. Some users even preferred to improvise key definitions based on their own understanding, which often resulted in mistaken use of lookalike letters and diacritics. Keyboard layouts have also failed to provide for Amazigh minority populations around the world, and have considered the multilingual context of Amazigh language use only locally. Several scripts are commonly used to write Amazigh variants, and even within a script there are different orthographies in use. Some orthographies are formal 1 I use the term 'language variant' since distinguishing 'dialect' and 'language' is not necessary here. ~ 165 ~ LES RESSOURCES LANGAGIERES : CONSTRUCTION ET EXPLOITATION standards. In others, some features are obsolete but still in use, some features are still disputed, and some features are regional usages or personal initiatives, or are required only for writing more phonetically. Complete descriptions of phonology and orthographies are often difficult to find. It is therefore complex to determine, for each script, a sufficient and practical superset of features for writing a large set of language variants so that keyboard layouts can be harmonised. This project began because I was creating a Kabyle dictionary document for my own use and existing Amazigh keyboard layouts did not produce a suitable set of letters. Keyboard layout design ties in closely with Unicode encoding, fonts, and font rendering capabilities of software. To facilitate good design, the project spawned a separate but related investigation into the possible ways of encoding Tifinagh text based on the existing Tifinagh set in Unicode, and their effectiveness in representing different regional Tifinagh repertoires and orthographies. The results of the investigation (Anderson, 2010a) were submitted to the Unicode consortium and considered by the Technical Committee in late 2010. The investigation also led to two of the letters that were presented but deferred in the original Tifinagh Unicode proposal (Andries, 2004) being proposed (Anderson, 2010b) and accepted into the encoding process by the consortium. Quality Amazigh keyboard layouts would allow easy production of well-encoded text. Their widespread use, with fonts of equivalent standard, would promote good document production without mistaken use of look-alike characters or diacritics, and stimulate creative output. Quality layouts would also promote the use of Unicode, consistent with other languages, and show a solid base in technology for Amazigh, boosting its prestige. Further, if all regional keyboards could be used to type converged literary forms of Amazigh, there would be no technical barrier to prevent experimentation and adoption by potential users. Also, if keyboards could be used to type many regional forms, writers of a variant would easily be able to type it correctly even in a place that used a different standard orthography. It would be easier to become familiar with other variants. Freely available keyboard layouts (and fonts) that were reusable across Amazigh variants would allow resources to be pooled to achieve high quality more quickly. These tools would form a stable foundation for work in other areas of technology for the language and in language maintenance. ~ 166 ~ LES RESSOURCES LANGAGIERES : CONSTRUCTION ET EXPLOITATION This project's results are intended to fulfil those needs. Viewing the scripts and all the varied orthographic solutions within them as writing tools to be evaluated and adapted across all Amazigh variants, encourages technical evolution of the writing systems, and also creativity in Tifinagh typography. Local traditions become simply styles of writing Amazigh, rather than constraints. The Tifinagh script and its future belong entirely to writers of Amazigh. 2. Aims The project targeted typing Northern Amazigh in Latin script across Morocco and Algeria, and typing as many major Amazigh variants as possible in vowelled Tifinagh (to provide support for the latest orthographic advances). Prioritisation of Amazigh variants was by level of representation in modern Amazigh literature and by whether they are currently written in either the Latin script or Tifinagh. Arabic script was judged out of scope2, as an ordinary Arabic keyboard can be used, and Arabic Amazigh orthography is not official or prevalent (though it has significant representation in modern literature in Morocco, on Algerian state television and some official Algerian websites). Here, I use the loose term 'Northern Amazigh' to group language varieties having one short vowel and three long vowels, distinguishing them from the 'Tuareg' varieties with their richer vowel repertoire, while recognising that varieties such as Siwi and Ghadamsi evade these categories. As well as local Amazigh variants, the project considered Northern Amazigh as a whole, targeting the superset of orthographic features needed for both Ircam's standard Amazigh and possible future converged forms. Similarly, Tuareg was considered as a whole. The project also examined the extent to which orthographies and text encoding could be shared across all Amazigh variants. The Latin style used in Algeria for Tuareg transcription was a priority, to cover Algerian needs also for Tuareg. Another priority was to include experimental features to allow a Latin transcription even more consistent with Northern Amazigh orthography. Support for West African-style Latin script for Tuareg was only a secondary aim because the Tuareg zone has Amazigh variants as recognised 2 Versions of the project's Latin and Tifinagh layouts adapted to match Arabic keytops might however be a useful future development for those used to Arabic keyboards or Arabic Amazigh orthography. ~ 167 ~ LES RESSOURCES LANGAGIERES : CONSTRUCTION ET EXPLOITATION national languages and there is official support for them in Latin script (but not for Tifinagh). Provision for typing Tuareg Tifinagh in classical style with limited vowel marking and with ligatures was similarly desirable but non-essential. Other Amazigh variants were to be covered for Latin and Tifinagh to the extent that information was available, but not necessarily for typing intuitively (letters could be fitted in ad hoc), and for transcription rather than practical use where there was no local Latin or Tifinagh writing tradition. The project aimed to provide drivers for keyboard arrangements covering the writing of the targeted Amazigh variants in Tifinagh and Latin. Each arrangement, for a set of variants, was to enable a complete set of orthographic features for a script – hence 'universal' – while remaining intuitive for typing its supported variants. If possible the letters were to be laid out similarly for different regions and scripts, so that users could type different regional forms, in either Latin or Tifinagh, without confusion, but with the Tifinagh layout remaining natural for Tifinagh and the Latin layout natural for Latin. The ideal was a single arrangement per script sufficient for typing all targeted Amazigh variants, and intuitive enough to be preferred for that script by users. One secondary aim was provision of obsolete features, to encourage users to adopt the new keyboard layouts and learn to bring their writing up-to-date. Another aim was to provide the ability to mix non-Amazigh languages. Another was to ensure that keyboard driver installation provides both Latin and Tifinagh capability together, for widest usability and to make it easy for Latin script users to try typing Tifinagh. The layouts were to target primarily the French AZERTY physical keyboard found across North Africa, but also to contain intuitive adaptations for other physical keyboards used in countries outside Africa with significant Amazigh populations. All adaptations were to have equivalent Amazigh capabilities, so that any supported orthography could be typed on any adaptation. Compatibility with Ircam's Tifinagh keyboard was a priority as an established standard. Windows and Linux were to be the initial target platforms, in that order. Windows installations are widespread and familiar to users, and were the primary target. Linux is easy to contribute to, free, known in North Africa, and likely to grow in use there as technical knowledge of it increases, so it was the secondary target. ~ 168 ~ LES RESSOURCES LANGAGIERES : CONSTRUCTION ET EXPLOITATION Apple is significant in publishing, and in mobile devices.

  • How to Enter Foreign Language Characters on Computers
    How to Enter Foreign Language Characters on Computers Introduction Current word processors and operating systems provide a large number of methods for writing special characters such as accented letters used in foreign languages. Unfortunately, it is not always obvious just how to enter such characters. Moreover, even when one knows a method of typing an accented letter, there may be a much simpler method for doing the same thing. This note may help you find the most convenient method for typing such characters. The choice of method will largely depend on how frequently you have to type in foreign languages. 1 The “ALT Key” Method This is the most common method of entering special characters. It always works, regardless of what pro- gram you are using. On both PCs and Macs, you can write foreign characters in any application by combining the ALT key (the key next to the space bar) with some alphabetic characters (on the Mac) or numbers (on PCs), pro- vided you type numbers on the numeric keypad, rather than using the numbers at the top of the keyboard. To do that, of course, also requires your NumLock Key to be turned on, which it normally will be. For example, On the Mac, ALT + n generates “ñ”. On the PC, ALT + (number pad) 164 or ALT + (number pad) 0241 generate “ñ”. A list of three- and four-digit PC codes for some common foreign languages appears at the end of this note. 2 The “Insert Symbol” Method Most menus in word processors and other applications offer access to a window displaying all the printable characters in a particular character set.

  • Belgian AZERTY Keyboard
    Belgians, Flemings: Demand your Swiss Keyboard! Serge Y. Stroobandt Copyright 2013–2015, licensed under Creative Commons BY-NC-SA Belgian AZERTY keyboard Three variants: French, Belgian and Tamazight (Berber). The AZERTY layout is used in France, Belgium and some African countries. It differs from the QWERTY layout in this: • The location of the [A] and [Q] keys are interchanged. • The location of the [Z] and [W] keys are interchanged. • [M] is moved to the right of [L] (where [; :] is on a US keyboard), • The digits [0] to [9] are on the same keys, but to be typed the shift key must be pressed. The unshifted positions are used for accented characters, • [Caps lock] is replaced by [Shift lock] , thus affecting non-letter keys as well. However, there is an ongoing evolution towards a [Caps lock] key instead of a [Shift lock] . It is used by most French speakers based in Europe, though France and Bel- gium each have their own national variations on the layout. Luxemburg and the French-speaking part of Switzerland use the Swiss QWERTZ keyboard. Most of the residents of Quebec, the mainly French-speaking province of Canada, use a QWERTY keyboard that has been adapted to the French lan- guage, although the government of Quebec and the Canadian federal gov- ernment stipulate and use the Multilingual Standard keyboard CAN/CSA Z243.200-92.[1][2][3] Het is de meest gebruikelijke indeling in België en in Frankrijk. Het toetsen- bord is ontworpen om gemakkelijk Franstalige teksten te kunnen invoeren, doch wordt niet alleen in Franstalige gebieden gebruikt: in heel België, waaron- der het Nederlandstalige Vlaanderen, is AZERTY de norm.

  • An Improved Arabic Keyboard Layout
    Sci.Int.(Lahore),33(1),5-15,2021 ISSN 1013-5316; CODEN: SINTE 8 5 AN IMPROVED ARABIC KEYBOARD LAYOUT 1Amjad Qtaish, 2Jalawi Alshudukhi, 3Badiea Alshaibani, 4Yosef Saleh, 5Salam Bazrawi College of Computer Science and Engineering, University of Ha'il, Ha'il, Saudi Arabia. [email protected], [email protected], [email protected], [email protected], [email protected] ABSTRACT: One of the most important human–machine interaction (HMI) systems is the computer keyboard. The keyboard layout (KL) dictates how a person interacts with a physical keyboard through the way in which the letters, numbers, punctuation marks, and symbols are mapped and arranged on the keyboard. Mapping letters onto the keys of a keyboard is complex because many issues need to be taken into considerations, such as the nature of the language, finger fatigue, hand balance, typing speed, and distance traveled by fingers during typing and finger movements. There are two main kinds of KL: English and Arabic. Although numerous research studies have proposed different layouts for the English keyboard, there is a lack of research studies that focus on the Arabic KL. To address this lack, this study analyzed and clarified the limitations of the standard legacy Arabic KL. Then an efficient Arabic KL was proposed to overcome the limitations of the current KL. The frequency of Arabic letters and bi-gram probabilities were measured on a large Arabic corpus in order to assess the current KL and to design the improved Arabic KL. The improved Arabic KL was then evaluated and compared against the current KL in terms of letter frequency, finger-travel distance, hand and finger balance, bi-gram frequency, row distribution, and most frequent words.

But the Romanization you are supposed to use for the word processor is not quite the same as the one you learned in class. You have to interpret Romanization as a mere substitution for the written syllables, HIRAGANA. You first have to consider how the word you want to type is written in HIRAGANA and then transcribe each HIRAGANA character into corresponding romaji. After typing in the Romanization, hit ‘Enter’ key (do not hit ‘Space’ key before hitting ‘Enter’ key, that will convert HIRAGNA into Kanji). Hit space key after each word if you want to have a space.

    TRATHCLYDE S DISCUSSION PAPERS IN ECONOMICS LOCK IN, PATH DEPENDENCE, AND THE INTERNATIONALIZATION OF QWERTY BY NEIL M KAY NO. 13-10 DEPARTMENT OF ECONOMICS UNIVERSITY OF STRATHCLYDE GLASGOW Lock-in, path dependence, and the internationalization of QWERTY Neil M. Kay Department of Economics, University of Strathclyde e-mail for correspondence: [email protected] 1 “Professor Kay’s simulation technique, applied to French and German texts and QWERTY’s European cousins, could show whether Sholes solution works in these other environments”. (Stephen Margolis,2013, A tip of the hat to Kay and QWERTY, Research Policy) 2 Abstract This paper looks at the emergence of what is described here as the QWERTY family of standards (QWERTY and its international adaptations QZERTY, AZERTY, and QWERTZ). QWERTY has been described as an inferior solution and an accident of history. However, the analysis here finds that each member of the family represented highly efficient adaptations to specific user needs and technical challenges encountered in their own environments. These findings may be seen to have wider implications given QWERTY’s role as paradigm case in the literature on increasing returns and path dependence, and these are pursued in the paper 3 1. Introduction Increasing returns and path dependence have become two of the most influential concepts in modern social science. Arthur (1983 and 1989) and David (1985) created much of the foundation for later work and while the initial applications were mostly economics-oriented, it has subsequently had major influences on areas as diverse as the location of cities, strategic management, and the development of languages and legal frameworks.
