== Why i want to work with the Swathanthra Malayalam Computing ==
To make a good contribution to open source which would make typing in indian languages as well as English and other European languages in fast and efficient using reduced number of keys(6)and for helping native malayali and other indian visually impaired persons.
== Why should we choose you over other applicants ? ==
I've been working for open source for more than three years. and i want to remain all of my applications as open source. from the below mentioned facts I prove myself to be the apt candidate to take up the proposed project.
== Proposal Description ==
I express my gratitude to swathanthra malayalam computing for accepting my idea of six key approch of br for producing textXKB,Gtk and QT. I here by express a brief overview of my project.
Braille is a writing and reading system using six raised dots. As a night writing method of writing developed by Charles barbier, it has been perfected by louis braille. The most relevant feature of braille system is that the world community became successful in creating a '''unified code for all the languages based on its phonetics.'''
[ Bharati braille] is a largely unified braille script for writing the languages of India. which use a 6-dot cell with values based largely on English Braille. It consists of 11 scripts including malayalam. Letters are assigned as consistently as possible across the various regional scripts of India as they are transliterated in the Latin script, so that Hindi, Urdu, Bengali, and English are rendered largely the same in braille. also bharati braille retains all the basic conventions relating to the representation of numerals, punctuation and special symbols just as in standard English Braille. Like english indian languages also have [ contractions] and special abbreviations which make text writing faster than normal, for example hear is the [ Grade-3] contraction list for English.
It is in consideration of this fact, lot of apps has braille output along with the screen readers(BRLTTY with orca)and braille translators (Dots,Liblouis). At the same time '''there is no input method using the six key approach of the braille to produce text.'''
Application's which are currently available in Linux Repositories.[edit][ BRLTTY] : is a background daemon which provides access to the linux console for a blind person using a refreshable braille display -
[ Dots] : - Dots is braille typesetting program for Linux, it can translate XML and MS DOC files and displays it both ASCII and braille dot notation.
[ liblouis] : - provides Braille translation and formatting for a large number of languages and Braille codes.
[ Orca] : a screen reader which support Braille refreshable display's
[ Sharada-Braille-Writer ] : one of my projects, it is a simple text editor which use six key approach of brailler to input text. But it has a big limitation that is it cannot be used for other application as a layout works.
[ Tuxtype] : A interactive game which help Since there is no existing braille layout, My plan is to learn make a Braille with six key layoutKeyboard layouts extension for XKB.
Since there is no existing braille input mechanisam, My plan is to make a common library which can be used
with X11,Wayland,Gtk and QT by creating adapters.
== Relevance of six_key_layout braille as an input.== 
1. it is very simple, uses only six keys of the keyboard.
4. braille is a highly efficient system for it can use contractions and abbreviations and it can enhance the text production speed to a great extend.
5. braille is a world standard and a braille input method will make it accessible and user friendly for visually impaired, persons with limited hand movements and visually impairedmovement, dysluxic
6. It can lead to designing small keybords that can be used with tablets.
== Any relevant experience you have ==
I have already developed the applications in this direction named Sharada-Braille-Writer. It is a text editor using six key approach to produce print in different Indian indian languages along with english.And also i have developed braille extension for Tuxtype.
Brailler is an equipment for producing braille(6 dots) materials in a fast and efficient manner, so i selected f, d, s, j, k and l representing 1, 2, 3, 4, 5, and 6 dots of the braille system.
f j 1 4 d k 2 5 s l 3 6
This will Create a Braille module and framework for XKB. for which use the mapping files of key(to be pressed '''simultaneously''') -> letter.Eg:
f a
In order to produce 'a' one has to press 'f' and for 'b' 'f' and 'd' '''together''' to be press, and for 'c' f and j like, 'h' will be used for letter deletion and 'g' and 'h' together for word deletion. There will be two main lists for each languages. They are beginning list and middle list.The beginning list will contain consonants and vowels middle list will contain vowel signs. The beginning list will be as follows f അ sjk ആ dj ഇ sk ഈ fsl ഉ fdkl ഊ dl എ fk ഏ sj ഐ fsjl ഒ fsk ഓ djl ഔ[ >> View complete Malayalam Beginning list ] And middle list will be as follows sjk ാ dj ി sk ീ fsl ു fdkl ൂ dl െ fk േ sj ൈ fsjl ൊ fsk ോ djl ൗ[ braille -3/blob/master/share/pyshared/sbw2/data/malayalam/middle.txt >> View complete Malayalam Middle list ] abbreviation key will be 'a'. Pressing 'a' after typing a abbreviation will replace current word(abbreviation) with it's expanded form. abbreviation list will be as follows ab about abv above ac according acc account ack acknowledge ackment acknowledgement acr across af after ag again agr agree[ >> View complete english abbreviation list ] Contractions list will be saved in different maps named with respect to there dots used. Unlike Braille we have to press contraction key before typing the letter to get the word. [ >> View English Dot 4-5-6 contraction list] '''It is nice to see that [ Wayland] and [ Mir] also using [ XKB] like X Window System.[ see hear ] map files for wayland, [ see hear] for MIR''' === Approach - 1 ===1 - Develop Gtk/Qt modules that will automatically and change the editable to braille mode. Hear we use key-release event from editable to implement this. The beginning list will be loaded at first. When user type something the middle list will be loaded and will continue in middle list till user press a space or enter. In this way the users don't have to switch manually from vowel to vowel sign and vice versa. Also there will be a special key to manually switch between the beginning and middle list. This is really what i have implemented on Sharada-braille-writer. 2 - Develop braille XKB module for XKB witch would not include contraction and abbreviationsthis will be active automatically when we are in none QT/Gtk application. Hear we can't implement a list jumping mechanism which is against the concept of modular approach. So we use an extra key(may be semicolon) to simultaneously pressed with vowels sign to get vowels. Pros : Easy to implement User not to be concern about vowels and vowel signs during typing which make typing simple and fast. Follows Perkins brailler approach in Gtk/Qt apps. Each layers are independent.Cons : User has to switch between layouts while using Gtk/Qt app or others. Duplication exist=== Approach - 2 ===
1 - Develop braille module for XKB as mentioned above.
2 - Develop plugins Create plugable braille extention for Qt GTK and Gtk which can QT. This will be used with Qt and Gtk apps.These are only Integrate third grade contractions for supporting braille layout(from XKB) to enable contractions english and abbreviations. These plugin will check current layout and if it is braille it will enable contractions and abbreviations with respect to current braille languagemalayalam.
Contractions list will be in the same layer. It will override XKB layer. Unlike Braille we have to press contraction key before typing the letter.if any contraction Add punctuation and numerals as separate map with that combination is available the Gtk/Qt plugin will load corresponding word for next user typed letter. if not it will simply give letter for that combinationthese two extentions.
Pros : Same Integrate Orca screen reader(via making orca script) along with this XKB layout in everywhere. There exist so that there exists no duplication in any of layers. Cons : Implementation is not easy User have to use extra key to get vowelsaccessibility issue. Not following Perkins brailler
''' The gtk and qt part will be done by creating respective im modules. in this way user can switch to braille mode by setting environmental variable (export QT_IM_MODULE=braille). for more details [ see hear for QT] and [ see hear for Gtk ]. '''
