Re: Accessibility for person with a motor disability

[Mats L]

 Eric,

It's always very good to have a person speaking on behalf of himself or
herself as a user representing an actual need. There is a lack of this for
people with mobility based access problems in these forums for free
software, compared to the areas of low or no vision. Part of the problem is
the really wide and diverse range of needs regarding physical access -
disabilities as well as abilities. (Regarding cognitive disabilities and
needs there is a general lack of people at all able and interested in
speaking and doing things on behalf of those needs in the GNU/Linux world.)
So thanks for stepping in! I'll be looking at your ideas with great
interest.

I can agree with some of what you're saying, but not with all of it. I can
definitely in great parts understand and share your frustration and
dissatisfaction about the situation. I agree with and can confirm your
picture of the situation regarding speech recognition in the GNU/Linux
based environments. We don't even have decent text-to-speech solutions for
wider user needs (even in English and major languages, far less in smaller
languages - see for example
https://opensource.com/life/15/8/interview-ken-starks-texas-linux-fest).
But remember that speech input is a dead end for a large part of users with
mobility based access problems, those who have impaired or no speech.

Eye-gaze input is another hot area where it seems unrealistic to expect any
decently competitive and user-friendly solutions in the free software
domain in any near future.

This said, I think it's very good to have Alex ask these questions about
what's available. A decent awareness about the state of the art is always a
necessary starting point for some improvement. And people have difficulties
even finding their way to existing solutions. Things like decent
head-tracking, on-screen keyboards (OSK) etc are really important to have
available, and are life savers for some users, even though there is a huge
potential of improvements.

One thing that makes me frustrated is the sustained tendency of unnecessary
fragmentation and lack of collaboration even in this area of handling basic
accessibility needs. Why don't for example the people involved in
maintaining and developing Caribou and Onboard team up and unite on one
common OSK with a wider range of functionality and options - for all
GNU/Linux distros and flavours, and with support from them?

Dasher is really an example of the
kind of needs based, unorthodox and innovative solutions for text input
that you were asking for. Have you tried it? As a second best, compared to
excellent speech recognition, I think it could be relevant for you? But
there I guess we now also have a problem with continued maintenance since David
MacKay  so unfortunately
passed away.

Maintaining decent accessibility for all in an ever changing ICT universe
is not an easy task, and particularly not on the free software platforms it
seems, so far ...

I also think part of the challenge with providing mobility related
accessibility features is that those of us who are technical enough to
understand what to do no longer have hands to make it happen so we count
on people like you to work with us building prototype features. I did
that with togglename when I had enough money to pay somebody to write
code for me.

Yes. Speech recognition is useful only if the person has a functioning
vocal apparatus. I'm reminded of this every time I get a cold. :-)

This is a place where a foundation could really help. Like you point
out, all the accessibility features we have are really important and can
mean the difference between watching the clock tick for the rest your
life and being able to participate in society at some level.

I wish there were some foundation money to help us build new interfaces,
not accessibility tools but different interfaces for using tools like
speech recognition, I tracking, head tracking etc. to operate in larger
chunks and not emulating the fine-grained motions of a mouse or keyboard.

You've hit on a really big issue. Too much fragmentation, not enough
concentrated support to solve the problem and use it everywhere.

dasher doesn't work for me because I can't move the mouse fast enough or
accurately enough to pick off letters and I'm terrible at spelling. By
the way, that's a serious side effect of using speech recognition. Your
ability to spell degrades...

For a while, I was going to the local A11y meet up and when I described
my issues, I got back a bunch of blank looks. These people had no idea
how to deal with accessibility needs like mine. part of the challenge of
using speech recognition is not just the speech recognition and the
application modifications but it's that using speech recognition in open
office is kind of counterproductive to other people's work. It's about
as easy to relax and speak as it would be to try to take a pee in a
bucket in an open office.

So if you want, I'll be glad to keep chiming in and be as constructive
as possible. If someone feels like trying to prototype fitting the
Dragon browser extensions into something like electron, I'd be glad to
work with them.

That goes for switch users too: Dasher may be very efficient for text entry
(if you are a relatively fluent reader and can learn to cope with the
navigation mode), but you will need an appropriate OSK for editing and for
the handling of your system in general.

Dasher comes to mind:



I've tested it, looks good to me.
Is Dasher should be configured to replace the keyboard when I open a 
text edition field? I've found how to write text but it's only from the 
dasher window so imagine if I would like to enter text on Firefox, how I 
can do that? Maybe there is a documentation I could look on? (I've 
already read some documentation I've found on the dasher website).


Dear Alex,

Dasher has a "direct mode" that you can activate from le File menu. In 
this mode, you can click in a text input widget in any application and 
come back to dasher window to type text that will directly appear in 
this widget. I have typed part of this e-mail this way in thunderbird 
using dasher.


I don't use dasher on a daily basis myself, so I can't judge whether 
it's reliable or practical for daily use. For sure it does not play nice 
with mouse or sloppy focus.


Also, due to how it is implemented, direct mode works only under X11, 
not in Wayland:

https://bugzilla.gnome.org/show_bug.cgi?id=778151

So by default direct mode works in Debian Stretch (current stable), but 
not in Buster (current unstable).


Kind regards, Thibaut.

We need more than just an accessibility tool, we need a different way of
accessing functionality and data embedded in applications. I've been
trying for years to figure out how to write code by speech and here's
the current state of thinking. I did this is a proposal to github for
talk it github universe.

https://docs.google.com/document/d/1M14DEoC2uTWtQv1HtRyUwK5NKT6Wb0vutu98F9Yl1b0/edit?usp=sharing

It just occurred to me that another example of building your own
interface for the moment is what I'm doing right now. I'm extracting
bank statements to give to my accountant for tax prep. When you download
a statement, my bank labels every statement PDF.pdf. Yeah, I was
thinking the same thing. So I built a grammar that I can say "statement
in June" and it creates a file name of "1234-2018-06.pdf". I still have
to, display in PDF and then click the download button before I can get
to the point where I need to enter a filename but being able to generate
filenames by speech makes it much easier.

I'm not using a GNU/Linux distribution because well people of promised
speech recognition on Linux for as long as I've been disabled and it
just hasn't happened. what I use is Windows with NaturallySpeaking and
what ever hacks I can get to drive free software. I'm missing tons of
functionality that's present in NaturallySpeaking plus word (i.e.
Select-and-Say and easy misrecognition correction) but I do what I can.

I think it's safe to assume that we will not see speech recognition on
linux in the near future. there are at least a half a dozen projects I
can name off the top of my head that were going to provide speech
recognition on Linux "any day now". If you going to use speech
recognition today, the recognition environment must be available now. 

The question then becomes what can we do if we put speech recognition
"in a separate machine" like a VM or an android phone. the idea is to
isolate the nonfree components so that a disabled person can make a
living, participate online etc. using a mostly free environment. I
propose this because the assumption that every machine should be
equipped with  the accessibility tools the user needs raises the cost of
accessibility and limits the disabled user to just one machine that has
been customized for them. If on the other hand, if we put the
accessibility interface in a separate box like a smart phone and provide
a gateway to drive applications then many more machines could be made
accessible at very low overhead.

remember what I said about solving the disabled person's needs? As I
said to one free software advocate, take care of the needs of the
disabled person to make them as independent as possible, to earn a
living, to live a life first. Advocate free software second if it fits
their needs. I know this is not a popular attitude in some circles but,
quite frankly if I had to wait for speech recognition from the free
software community, I would be living on disability, wasting my life
because I wouldn't be able to work, I wouldn't be able to go to school,
and I just can't tell you how many things you lose when your hands don't
work right.

I'm frustrated by this kind of question because frequently, this is the
wrong question. you should be asking what is the appropriate interface
to enable the person with a disability to write, and more importantly,
edit text.  much of this thread has been proposing answers based on
what's available, not what the person needs.

I can't use keyboards much because of a repetitive stress injury. I
would say that the most efficient way to write text with a head tracking
software is to not even try at all. It's the wrong tool. For many kinds
of mobility-based disabilities (RSI, arthritis, amputation etc.) speech
recognition would be a better tool.

your question touches a hot spot for me because I've been living with a
disability for about 25 years now. I've also seen, for the same 25 years
people without disabilities proposing the same solutions over and over
again, either not able to or unwilling to hear that those solutions are
, at best crap, at worst humiliating.

As a person with a disability, I will tell you anytime you try to
emulate/simulate a mouse and keyboard with tools like on-screen
keyboards, I tracking etc.,  you are solving the wrong problem. the
right problem (my opinion) is digging into applications and revealing
internal information and providing access to internal controls so that
you can build an interface that matches the person's disability.

It's also very important to build the interface it lets the person
automate or extend that interface without counting on anybody else to
create that extension. For example, my hands don't work right so if I'm
going to extend my speech recognition interface, I need to do it with
speech recognition.

So I would go back to your disabled person and really look at what they
need. If they have enough physical ability enabling them to use speech
recognition, then that will make them more independent than head
trackers or on-screen keyboards would ever do.

Both Onboard and Caribou were intended as replacements of GOK, but are not
really.
GOK was an ambitious effort to provide tailorable access for individuals
with major motor difficulties, including need for single and double switch
input. But it was not a very suitable option for a wider group of users
with a need for a more basic on-screen keyboard for use with direct point
and click or touch selection.

Onboard and Caribou are more of that later kind, but lack features for the
previous kind of user needs.

So there we are, lacking an on-screen text input, communication and
computer control tool covering the full range of needs reasonably well, or
a couple of alternatives covering the full range of needs (including users
who are not fluent readers and writers).

Dasher is indeed a very interesting text generation tool for some users,
but again, not for all. I haven't properly tested Dasher in GNU/Linux
environments. On Windows there is a setting in Dasher where you select
whether text shall be sent to Dasher's own text field (with options to copy
and paste it into a target app), or whether it shall be sent directly to
the current active target app. I a not clear about if and/or to what degree
this is supported on various Linux distributions.
Anybody ?

Re: Accessibility for person with a motor disability

[Mats L]

Hi Alex and all,

I can confirm Cesar's description of the functionality of eViacam as a very
objective and accurate one (despite - or thanks to - his direct involvement
;-)

I have been doing som content management for OATSoft for several years, but
unfortunately the maintenance broke down a couple of years ago because of
server hosting problems etc outside of my control. In addition to Gregg's
link to the Unified Listing  (which is a very
comprehensive database merging data from many sources, but also a bit messy
and not specific for free software), there is also another new attempt to
replace the function of OATSoft in the OpenAssistive
 initiative. This latter is not yet very
comprehensive as it is new and depends on user input. I suggest that we all
check out these resources and try to help adding missing bits and pieces
and keeping them up-to-date for free software solutions.

Regarding access alternative solutions for GNU/Linux there is also the
Caribou on-screen keyboard:
https://wiki.gnome.org/action/show/Projects/Caribou. This is a rather basic
on-screen keyboard tool. It has been developing slowly, but I have noticed
some recent activity via the bug tracker.
Unfortunately the GNU/Linux environments are badly missing a full-featured
tailorable on-screen keyboard alternative (including switch input etc.)
following up on the GOK
project
since it was discontinued.

Cheers,
Mats

IIRC that has never been implemented.  It would be a matter of making it

* Does head-tracking is really efficient?


(Disclaimer: I'm the author of eViacam and EVA Facial Mouse)

If by efficiency you mean achieving the same throughput than a regular mouse, 
then the answer is no. I'm not aware about any head tracker solution able reach 
the same low difficulty level (in terms of the Fitt's law) and interaction 
speed as the mouse. In other words, interacting with the computer using a head 
tracker is slower than using a mouse.

However, if you mean whether is there a FOSS head tracker solution available 
for GNU/Linux as efficient as similar products, then I would say yes. I know 
about some eViacam users that say that it is almost as accurate as the best 
hardware based commercial solutions. This, of course, is opinionable and user 
experience depend on many factors such as practice and working conditions 
(quality of the camera, lighting, etc.).


* Do you know if there are other useful application? 


There was a website that collected many open source assistive technology 
software (not only for GNU/Linux). The site is now gone but could be still 
consulted here:

Hello all,

To help people with motor disability, I'm trying to search what software and 
technologies exist on GNU/Linux.

Sorry for the cross-list post but I don't know where to ask for help.

I've already found the following software:
* dasher: for writing text
* eviacam: a head tracking software
* mousetrap: another head tracking software
* onboard: a configurable on-screen keyboard

My questions are:
* Do you know if there is eye-tracking software?
* Does head-tracking is really efficient?
* Do you know if there are other useful application?
* Do you know how to use the numeric keyboard to move the mouse on Mate?
* Is there a mailing list or forum where there are people with motor disability 
using GNU/Linux?

Best regards.

Re: Accessibility for person with a motor disability

[Gregg Vanderheiden GPII]

have you tried the Unified Listing? http://ul.gpii.net  part of  
http://GPII.net  

use advanced search (or standard search) and type Linux in the search box.

I found 63 hardware and software accessibility products that cite LINUX in 
their descriptions.

Don’t see any eye trackers listed - but you can check with the mfgrs of all of 
the 30 products that include "eye track” in their descriptions to see if any 
work with LINUX.  (if you find one - please leave a note using the handy 
feature at the bottom of every page — so we can get LINUX added to the 
description.
