=== 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 module for XKB witch would not include contraction and abbreviations
this 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.


Create plugable braille extention for GTK and QT. This will be
2 - Develop plugins for Qt and Gtk which can be used with Qt and Gtk apps.
 
These are only for supporting braille layout(from XKB) to enable contractions and abbreviations. These plugin will check current layout and if it is braille it will enable contractions and abbreviations with respect to current braille language.
Integrate third grade contractions for english and malayalam.


Add punctuation and numerals as separate map for these two extentions.
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 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 combination.


Integrate Orca screen reader(via making orca script) along with this XKB layout so that there exists no accessibility issue.
Pros :
Same layout in everywhere.
There  exist no duplication in any of layers.
Cons :
Implementation is not easy
User have to use extra key to get vowels.

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)


Do you have any past involvement with the Swathanthra Malayalam Computing or another open source project as a contributor ?

with swathanthra malayalam computing i used to share ideas and attended meetings, i have produced opensource software for visually impaired on opensource platform(it is mentioned at the end of this proposal).


Did you participate with the past GSoC programs, if so which years, which organizations?

Yes in 2013 with Tux4kids, This is my second time.


Do you have other obligations between these months ? Please note that we expect the Summer of Code to be a full time, 40 hour a week commitment ?

No , I don't have any other commitment. I am willing to put the required hours during GSoC period.


Will you continue contributing/ supporting the Swathanthra Malayalam Computing after the GSoC 2013 program, if yes, which area(s), you are interested in?

Yes i will continue maintain this gsoc project along with my all other open-source applications.


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 for producing text. 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. 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 to learn Braille with six key layout.

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 as an input.

1. it is very simple, uses only six keys of the keyboard.

2. It is specially important for indic languages which use more than fifty alphabets.

3. Having the same code for all the languages of india unified, known as bharathi braille there is no need for learning different layouts.

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 persons with limited hand movements and visually impaired

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 languages along with english. And also i have developed braille extension for Tuxtype.


How i intend to implement my proposal

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 use the mapping files of key(to be pressed simultaneously) -> letter. Eg:

f      a
fd     b
fj     c
fsjl   x
fdsjk  q
....

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

And middle list will be as follows

fsl  ു
fdkl ൂ
dl   െ
fk   േ
sj   ൈ
fsjl ൊ

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

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.

It is nice to see that Wayland and Mir also using XKB like X Window System. see hear 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 module for XKB witch would not include contraction and abbreviations this 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

2 - Develop plugins for Qt and Gtk which can be used with Qt and Gtk apps. These are only for supporting braille layout(from XKB) to enable contractions and abbreviations. These plugin will check current layout and if it is braille it will enable contractions and abbreviations with respect to current braille language.

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 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 combination.

Pros :

There  exist no duplication in any of layers.

Cons :

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 .

Additional

Add map file for other indian languages.

Add punctuation and numerals as separate map.

Add contraction and abbreviation maps for English,Malayalam and Hindi.

Create Gui(Gtk) for managing languages,adding,editing, removing map files, and editing abbreviation/contraction list.

Integrate Orca screen reader(via making orca script) along with this so that there exists no accessibility issue.

A rough timeline for your progress with phases
