Re: [ros-dev] no replies about making reactos accessible for the blind

[M. Ziggyesque]

The console itself is still a graphical user mode app; it or a DOS box simply 
uses a DefConsoleProc (sic) instead of DefWindowProc behind the scenes to 
manage the GUI aspects and system menu, and may use an OEM code page instead of 
an ANSI one in full screen mode. Windows may eventually be able to boot to a 
native mode full screen console instead of explorer, but that is real low on 
the priorities list, afaik.

The primary bar to using braille in the installer, that I see, is that it 
requires at least two code pages to represent various text and line delimeters 
and the 8 dots of graphics defined for it, or G0, G1 and G2 charmaps for 
systems that support ISO-2022, and the installer is only designed to use one 
code page, that maps to one defined GL and GR charmaps as inputs, for ANSI code 
pages. This is because no video card or terminal I'm aware of currently 
supports multi-byte encodings at power up / boot time as a hardware limitation, 
not software; at most a BIOS may use additional graphics for chars that index 
into the C0 and C1 charmaps on output, like with VGA/VESA's support for CP437.

The assumption has been boot time applications like installers would limit 
themselves to ISO-646 variants like ASCII, to make writing BIOS ROMs easier. 
People needing special peripherals like braille bump printers or bump scanners 
would have these supported once a sighted person configured their system for 
them.

You can if you implement a Win32 to console translator. Nothing is
impossible.

[ros-dev] no replies about making reactos accessible for the blind

[Dick]

Hi,
I did not receive anny replies about my question to make reactos 
accessible for the blind. I would really suggest to do that while building 
the os, instead of doign it when the whole system is fully built.

Re: [ros-dev] no replies about making reactos accessible for the blind

[M. Ziggyesque]

I'm not saying it isn't possible to support the hardware, just I have not seen 
any pre-boot environment that the installer might need to communicate with 
attempt to provide this support, so it is also available to whatever gets 
installed, after reboot. The installer may be fine using only 6-dot 
combinations, but I'd consider it likely some varieties of applications will 
assume all 8 dots may be input or output over the single channels most 
compilers support.

Braille will not be output by GPU, it will be output by CPU onto either
USB or serial Braille bumper. Two different output channels may use two
different codepages. If they were somewhat dependent as in multi-monitor
situation, you would need to drive both via GPU. However they are
independent output channels, which just happen to share contents.
Commonly used Braille is a six dot encoding and most letters and numbers
are encoded by this encoding. Eight dot encoding is used for music and
mathematical notations.

You unset the lower line of a 8-bit matrix and you get 6-bit display.
This is simple bit masking and will not require complex driver operations.

Jumping in here with a quick reply as a *lurker*, not a developer:

Don't think anyone would mind if you supplied patches :). You have to
understand, with people still working on kernel things, making applications
actually work, stop crashing, hardware support...

Most that would interface with screenreaders would *probably* be handled by
WINE anyway. Is there something specific you have a problem with not
working? If so, do file a bug report! But first check that the same fault
doesn't pop up with wine under linux.

The installer itself needs to be accessible enough. WINE does not use a
Windows style installer by itself.

Re: [ros-dev] no replies about making reactos accessible for the blind

[Dick]

Hi magnus,
unfortunately this is not how screenreaders work. screenreaders rely on 
accessibility libraries built into the operating system. running a windows 
screenreader in linux will not work, you need to use orc(the linux 
screenreader).
fortunately some realy helpfull packages are already ported to 
windows(brltty to use braille displays and espeak to give speech output). 
but these applications are just part of the proces. for example  when 
running brltty in graphic mode it will just show lines filled with the ? 
symbol.
the main problem of screenreaders is they have to find out what developers 
had done to make an app accessible. for example, when a screenreader give 
access to firefox version 40 that same version will probably run into 
problems when running version 60, the screen reader needs to be updated 
and adjusted to the changes made in the app. Reactos is an os built from 
the ground. what i think would be helpfull is to do it the other way this 
time: built functionality into the os to display just text on braille 
displays instead of graphics for example. when the accessibility is fully 
built into the os updated apps will have much less influence because the 
os itself is doing the tasks needed to make everythign accessible. I think 
it is a much harder job to build this into a fully finished os than to 
include such features in an os that is still in heavy development.

Some software will not work that way because they supply UI not text,
just images. That kind of software will not work with screenreaders nor
hi-contrast unless it is explicitly programmed for.

of course, you are right. but like in linux, much software can be ran

WINE's accessibility stuff is handled by underlying desktop's UI kit,
not by WINE itself.
