modified 6back for indian language script(s)

[peekay]

trying to include/attach .jpg file of th modified 6back for
use in entering indian language script(s) was not successful
when trying from gmail 'compose mail' page

(it works when emailing from outlook express .. using
insert picture .. not 'attach picture' .. the picture gets
inserted INTO the email, and appears in the post to
the group)

so, i have uploaded the picture gkos_indic.JPG
to the group's 'Files' section

hmmm...

I wonder what might the purpose of those extra keys if they just act
the same as pressing two adjacent keys. and then, you still have 3+3
fingers on them. - you can press any combination you wish without
those extra keys.

the purpose of the extra keys on a 6back device is simply to

make the user of the 10key h/w on the desktop/notebook pc

get the same 'feel' of '10key' usage when in reality he is

using a 6back device

 

the simpler logic on the QWERT YUIOP hardware where -

G1L1=QY (क..ka..grp1Ltr1)

(needs LL+RI .. LeftLittle & RightIndex fingers)

G1L2=QU (ख..kha..grp1Ltr2)

(needs LL+RM..LeftLittle & RightMiddle fingers)

G1L3=QI (ग..ga..grp1Ltr3)

(needs LL+RR..LeftLittle & RightRing fingers)

 

will confuse the user on a 6back IF -

G1L1 needs TopLeft+TopRight Buttons ..

(needs LI+RI fingers)

G1L2 needs TopLeft+TopRight+MiddleRight Btns

(needs LI+RI+RM fingers)

G1L3 needs TopLeft+MiddleRight Btns

(needs LI+RM fingers)

 

for the 2nd set of G1L2 (pressing TWO btns with TWO TopRight+MiddleRight fingers becomes a very different method on a 6back from the 10key h/w

 

Pressing  ONE btn with the  ONE MiddleRight finger on the 'modified' 6back device is simpler to understand (although the 'second' button actually pressed the first/top AND second/middle buttons of the 6back device)

 

> you can press any combination you wish without those extra keys.

teaching combinations of

Q+Y  or LI+RI,

Q+U  or LI+RM

Q+I   or LI+RR

Q+O or LI+RL 

Q+P of LI+RLextended

for both the 10Key AND 6back makes life much simpler

 

we can and shd presume that the user resistance to multiple key presses .. the logic .. the learning .. the practice .. all will face stiff resistance ..

 

learning to press only TWO keys for any and each character is much more 'acceptable' .. at least for indian script character .. with their unique 'grouping' structure already built into the character set

But it's no longer a 6 back, it's a 10back. It seems like you're
trying to invent a whole new piece of hardware.

Pressing multiple keys is the whole concept of a chording keyboard.

The grouping of the characters can still be maintained by using
chordons.

well .. it 'seems' like that .. but in reality, the 4 additional
buttons are not the same as the 6back buttons

in a 6back we have 6 live switches pressed by 3+3 fingers

this design remains the same ..

the additional keys are dummies which serve to press
TWO of the 6back's keys

what i am trying here is to make the user 'feel' that he
is pressing the second/fourth key when in reality
the first&second/second&third keys are being pressed
by the second/fourth key respectively

this is more like the logic of the 'ONE' button in some
recently launched notebooks which works like the
ctrl-alt-del trio but make life easy for training a new
user .. trying to make a NEW user understand that
sometimes THREE buttons have to be pressed all
together does 'confuse' some new users

> Pressing multiple keys is the whole concept of a chording keyboard.

true .. for me and you, it is an easy concept to understand ..
for a novice user (especially low education and poorer
section of indian script users), explaining chording concepts
with many keys being pressed simultaneously would confuse,
and further spawn resistance rather than acceptance

only TWO keys being pressed .. in permutation ..
(Q+Y giving different character than Y+Q) should
make teaching the raw hands a bit easier

yes .. but i guess using ONLY TWO keys even for chordon
will make things easier to implemnet

all this is not just my opinion and feeling .. but the result of
studying in great detail the many many types of input devices
(twidler, frogpad, agenda, cykey, shorthandWriter) and also
many s/w solutions using java/javascript

simplyfying things is a complicated process .. the solutions
usually don't show the tremendous hardwork that goes into
the 'simplifying' process .. like the years and years it has
taken to standardize the GKOS layout for the english alphabet

someone already has invented one .. checkout the picture (from the original website :

someone's invented another input method using the
number-keypad ..
(though the purpose is different..braille !)

http://www.iu.hio.no/~frodes/numpad.html

picture is in the 'Files' area of this group
(file name is numpad2.jpg)

this could be the way to use gkos in 6back
8back or 10back mode .. all we would need
to do is cover the numpad with a 2mm
acrylic (flexible-glass) sheet with opening
above the keys that we would want to use
