296 Proposal for Enhanced INSCRIPT keyboard layout 5.2 - submitted
by C-DAC GIST.3 HISTORY The first INSCRIPT keyboard was
standardized in 1986 under the auspices of the DOE. It was
subsequently revised in 1988 by a DOE committee and suitable
modifications were made to the then keyboard especially to
accommodate Nukta extended keys as well as to add certain matras
which were felt to be lacking. The last revision to the BIS
document was made in 1992, after which the document has not
undergone any revision. This was partly because very few new
characters were added to the ISCII code-set and these if at all
were handled by extending and generating out the character by the
use of the Nukta. The BIS document specifically mentions such
characters. Hence the INSCRIPT keyboards were felt to be
self-sufficient. With the advent of Unicode a few new characters
were added to each code-page; characters for which the BIS document
had not made any provision. In addition Unicode introduced the
concept of ZWJ and ZWNJ as well as that of normalization.These new
features had marked repercussions on storage as well as inputting
and an urgent need was felt for a revision whereby each and very
new character introduced in Unicode would be accommodated on the
keyboard and a uniform manner of entering data as well as storing
data would be devised.With this urgent requirement in mind, CDAC
GIST involved in the initiative all major players: IBM, Microsoft
and RedHat Linux 1 and hence in 2008, a joint meeting was organized
between CDAC GIST and senior representatives of these
multi-nationals to devise a common and uniform strategy for
inputting and equally important for storage. This would enable the
creation of one single keyboard and more importantly one single
storage, essential for all high-end NLP. A task-force was created
with two major briefs: 1. Evolve a design policy which would retain
the major features of the existing Inscript keyboard.2. Accommodate
on the keyboard all and very character proposed in Unicode 5.2 and
also ensure that the design could accommodate all future
additions.The present document is the result of the joint
deliberations of all these companies. 1 The names are provided in
alphabetical orderProposal for Enhanced INSCRIPT keyboard layout
5.2 - submitted by C-DAC GIST.4BACKGROUND TO THE Enhanced INSCRIPT
keyboard layout 5.2 :Implementation of Complex Scripts such as
those used for Indian Languages entails 3 different processes:-
Input - Display- Storage Unlike Latin Scripts (with a few
exceptions) where What you Enter is What you see and What is
stored, Complex Scripts do not have such a simple relationship. The
three processes are different and yet intricately bound to one
another. Thus to enter a ligature or a conjunct the user types the
two characters and joins them with the Halanta to generate out the
requisite display on the screen. The entry is done in a particular
manner, the display therefore shows a given shape, and the storage
can be or need not be the same as the Input keys.This particularity
of Indian scripts has marked repercussions especially with the
advent of Unicode. This is especially important in three
scenarios:a. Where the user feels a need for a given character
which is not in the Unicode repertory and which is therefore
generated out by storing the character in the Private Use Area and
providing a keyboard mechanism to access the character. The eyelash
ra is an example where different vendors have resorted to different
means to display the character on screen. b. Where the given
character(s) exist(s) but the user feels the need to display the
character(s) in a specific manner. A good example is the explicit
halanta where the user feels the need to show a character not as a
conjunct or ligature but as an explicit form composed of two
characters separated by a Halanta as in the case below::Within this
scenario the Inputting mechanism becomes a crucial player. While
Unicode has identified (to a certain extent) the unique glyphs or
graphemes of a given script, thereby ensuring a certain amount of
standardization, the very purpose of Unicode is defeated by the
different keyboards which allow different means of inputting a
given character in the scenarios shown above.c. Normalizing of
Data: This is especially the case where Unicode shows two variants
of the same character as represented by the sign: (Identical To). A
Vendor can choose one means or the other or even provide both,
thereby storing data differently. Normalization becomes a prime
issue in this case.Proposal for Enhanced INSCRIPT keyboard layout
5.2 - submitted by C-DAC GIST. 5Apart from the prime issue of
Usability (a person has to change the method of inputting to suit
the different keyboards put across by vendors), these lacunae have
serious repercussions in different areas:a. porting and
transferring a document input by one mechanism across OSs or even
within the same OS..b. all high-end applications in the area of NLP
such as Proofers, Checkers, Translation, TTS, CLIA to name only a
few; where storage plays a crucial role.c. Searching (especially
Search Engines) where the right storage ensures a rich search.d.
IDN where spoofing can occur because of such loop-holesBASIC
PRINCIPLESThe INSCRIPT keyboard is based on certain principles of
which the most important are: the division of the keyboard into
Vowel and Consonant groups on the middle two rows. the
accommodation of vowels as long and short on the same key, where
such distinction occurs the accommodation of consonants on the
basis of the Vargas with unaspirate and aspirate on the same key
the possibility to move from Indian scripts to Latin based scripts
a phonetic design which allows a person typing in one script to
type in any other script, thereby ensuring accommodation of all
Indian languages on one single keyboard.It was decided to retain
these features of the keyboard in the new design, but while
retaining these features, two additions were made:Make the
keyboards language dependent instead of the existing script
dependency. This ensured that the ecology of languages was
respected and users of each language had their own keyboard.
However the governing principle of the Inscript keyboard was
maintained in the sense that across different languages, as far as
possible the position of similar letters was maintained on the same
keys. Different positions were kept only for characters specific to
a particular script/language.The Enhanced INSCRIPT keyboard layout
5.2 provides three layers and this to accommodate all the extra
characters and yet make the keyboard as ergonomic and efficient as
possible.Layer 1: Keeping in view the Bi-Lingual facility provided
by the earlier INSCRIPT keyboard, this layer has English characters
and punctuations as mentioned in English-India keyboard.. Proposal
for Enhanced INSCRIPT keyboard layout 5.2 - submitted by C-DAC
GIST. 6Layer 2: All standard and commonly used characters are
accommodated here with Shift and Unshift positions. As far as
compatible this corresponds to the existing INSCRIPT keyboard.Layer
3: All new characters and which are not frequently used are placed
on Shift and Unshift positions in this layer. Here the principle of
Mnemonic ease is used i.e. the character is placed on a key which
corresponds as closely as possible to the character on Layer 1.
Thus which is accommodated in this layer is placed at the same
position as . The toggling between Layer2 and Layer3 will be done
through AltGr key. For those keyboards which do not have AltGr key,
Ctrl+Alt combination can behave as AltGr.Though toggling between
Layer1(which is English layer) and Layer2 will remain through the
Caps-Lock key as mentioned in Annexure-D of Bureau of Indian
Standard document for ISCII-91 which is as follows:The Inscript
overlay gets selected when Caps-Lock is active, otherwise normal
lower case English overlay gets selected.The document comprises In
the Part I, the guiding principles behind the design of each
keyboard are presented followed up in Part II by the keyboards
themselves and code-charts of Unicode 5.2 for ready
reference.Proposal for Enhanced INSCRIPT keyboard layout 5.2 -
submitted by C-DAC GIST. 7GUIDING PRINCIPLESThe revisions proposed
in the Inscript Keyboard are based on certain basic principles,
each of which is enunciated and clarified below. PRINCIPLE 1:
USABILITYThe super-principle has been one of USABILITY i.e.
backward compatibility to ensure that users who have mastered the
keyboard do not have to unlearn their touch typing and learn new
habits. In other words the existing keyboard layout will be
maintained as far as possible and new characters will be added
on.PRINCIPLE 2: COMPATIBILITY WITH MAJOR OPERATING SYSTEMSIndian
languages are used today on a large variety of Operating Systems
such as Windows, Mac, LINUX (various flavors). The Keyboard is
designed such that it will be compatible across the board for all
Operating Systems, ensuring that no new learning habits need be
mastered when one emigrates from one system to another. This issue
is particularly important when one migrates a document from one OS
to another, especially insofar as the character modifiers are
concerned. Character modifiers are devices to ensure that a
character is joined/not joined within an Indic syllable. These are
used for two ends: to provide variant display such as showing a
half consonant with a dead halanta or in its half form which does
not join to the next consonant as in the cases below: To create a
new shape which is not present in the Unicode list as in the case
of the eyelash RA or the JA_PHALA:This was accommodated on the
existing keyboard by the use of INV and the soft halanta generated
out by the HALANTA+NUKTA combinations. Different OSs deploy the 2
modifiers in different manners:OS Mechanism Joining Not
JoiningWindowsMicrosoftUniscribe ZWJ ZWNJWindowsCDAC GISTUniscribe
Halanta+NuktaStored as ZWJDouble HalantaStored as ZWNJMacintosh MIF
(automata) Halanta+Nukta Double halantaRedHat Pango ZWJ ZWNJFedora
ICU ZWJ ZWNJThe modified keyboard will allow for these modifiers to
be used so as to ensure compatibility across the board.Proposal for
Enhanced INSCRIPT keyboard layout 5.2 - submitted by C-DAC GIST.
8PRINCIPLE 3: PHONETIC PARALLELISMAs far as possible the principle
of phonetic typing has also been retained and a user familiar with
one language say HINDI can easily type in GUJARATI since the key
positions are the same. CAVEAT:The existing keyboard was designed
with ISCII as base which provided uniformity across the board for
all scripts. While Unicode which was based on ISCII 88 continued
this practice, with the result that in earlier versions of Unicode
offsets of characters were possible, with the addition of new
characters the principle is no longer valid and parallels between
characters in different languages/scripts are no longer possible.
This is especially the case with the last two rows of code-pages
for Indian scripts where a marked divergence is noted. However the
modified keyboard still tries to retain the principle of PHONETIC
PARALLELISM and thus the AVAGRAHA as well as OM are fixed on the
same keys.PRINCIPLE 4: BI-LINGUAL FACILITYOne of the corner-stones
of the existing keyboard is the facility of moving from an Indian
script to Latin and vice-versa. The principle has been retained in
the revised keyboard not only because of usability criteria but
also because Indian languages often mix English and Indian
language, not only for word but especially for punctuation markers
which are borrowed from Latin1PRINCIPLE 5: LANGUAGE-DRIVEN
KEYBOARDSImplementation of Indian Languages on the digital medium
is over two decades old and with the experience gained in the area,
a necessity to distinguish between SCRIPT and LANGUAGE has made
itself felt. In certain cases script and language are co-terminus;
but in scripts such as Devanagari or Bangla, there is no one-to-one
correspondence between script and language. Thus Devanagari itself
caters to official languages: Hindi, Sanskrit, Marathi, Konkani,
Nepali, Bodo, Dogri and Santhali (co-terminus with Ol-Chiki)
whereas Bangla is used for Bengali, Assamese and Manipuri
(co-terminus with Meetei-Mayek). Instituting this dichotomy between
SCRIPT and LANGUAGE has certain advantages: Greater knowledge of
the script grammar of languages has shown that each language draws
from a script a certain number of graphemes and uses them in its
own pertinent manner. It was therefore felt that key-boards be made
Language compliant instead of Script compliant. This would not only
cater to national identity by giving each official language its own
keyboard and font but would also allow for better high-end NLP by
making the key-board exclusive to a given language rather than its
script. In addition it will also lead to economy of representing
characters on the key-board. Thus 0973 Chandra A is coterminous
with 090D Devanagari Letter Chandra E, since depending on the
language (Marathi or Hindi) both characters represent the same
conceptual grapheme: the English AE Proposal for Enhanced INSCRIPT
keyboard layout 5.2 - submitted by C-DAC GIST. 9as used in /at/
/and/ etc. The economy derived from the language-driven key-board
will allow for new high-frequency characters to be accommodated on
the existing key-board without resorting to an over-lay (see
Principle 6 below). Finally the dichotomy of script/language does
not abrogate the principle of usability: experiments have shown
that a language-wise key-board is better acceptable. PRINCIPLE 6:
PLACEMENT OF NEW CHARACTERS & VISUAL PERTINENCEWhere a
character to be added will be used across the spectrum of all
Indian Languages e.g. Avagraha, Om; such characters will be placed
uniformly on the same position for all key-boards.Additional
Consonants will be accommodated on the consonant pad and additional
vowels on the Vowel-pad.Characters such as Chillu-Aksharam which
were hitherto derived by adding modifying a character will be now
visually represented on the key-board to ensure that the user can
see the character (s)he types.New characters which have a high
frequency of use will be placed on the existing keyboard to ensure
ease of typing. PRINCIPLE 7: EXTENSIBILITYThe keyboard will be
extensible to accommodate all new characters which may eventually
be added by future versions of Unicode.PRINCIPLE 8: BACKWORD
COMPATIBILITYAlthough this issue is really not pertinent to
keyboard design, since the keyboard impinges on storage, the design
of the extended keyboard will be such that earlier data made with
the older keyboards will be compatible with that produced by the
new keyboard.PRINCIPLE 9: VISUAL DISPLAYThe characters pertinent to
a given script/language and shown in the Unicode chart will be
shown on the keyboard to ensure ease of use.Proposal for Enhanced

13LANGUAGEWISE KEYBOARD LAYOUTSLanguage : English-IndiaENGLISH
INDIA KEYBOARDWith the mandate given by the Government of India
that the Rupee sign shall be represented by the symbol , an urgent
need was felt that the same be also integrated in the exiting
keyboards: both Inscript for all 20 Indian official languages using
Brahmi based script systems2. It was decided that the following
criteria be deployed in implementation of the keyboards:1. That the
rupee sign be integrated on two keyboards:QWERTY and INSCRIPT 5.2.
2. That the said modified QWERTY keyboard shall be implemented in
all Operating Systems as English-India keyboard and that the user
shall have the possibility of implementing the same for input with
the proviso that the said keyboard shall be similar in all respects
to the existing QWERTY keyboard with the sole exception of the
integration of the Rupee sign on ALTGR+4, this to ensure that
earlier keying habits are not disturbed.3. That the rupee sign be
placed on the same key on both keyboards to facilitate ease of
entry.The layout of the English-India keyboard is given below.The
character placement convention followed in English-India keyboard
is as shown below.2 A meeting of the same was held on Aug 31, 2010
and it was decided that the rupee symbol be mandated in the
keyboard and that it be placed on ALTGR +4 .Proposal for Enhanced
