Re: More flexible line length in browsing mode

Martin J. Dürst <duerst@...>
 

Hello Quentin,

Many thanks for your reply. Creating an issue is a good idea, but we first want to try to implement and test it ourselves. We will look at Tony's SentenceNav add-on for some ideas on implementation.

Also, if you can give us a pointer on where the code for breaking text into lines of equal length is, that would be fine. If there is another list for such questions, please just tell us.

Regards, Martin.

As Gene noted, the line length in NVDA is a simple number - and it doesn't
look to see if it can "just add the last word of a sentence". I can see
that it might be advantageous though, I would suggest the best thing to do
is create an issue on our tracker at:
https://github.com/nvaccess/nvda/issues requesting the feature.
Kind regards
Quentin.

I believe in browse mode lines are defined visually, I don't recall NVDA
setting that would define line length.

If you would like to read by sentences, you can install my SentenceNav

Hello everybody,

I have been using NVDA on and off for a few weeks. It's really a great
help. I'm new to this mailing list, so please forgive me if I'm asking
something old.

When reading text from a Web page, the text is read in "lines", and
the user presses arrow-down for each line. NVDA has a setting for line
length, which is at 100 characters originally. So well, so good.

What I find somewhat confusing, and possibly a place for improvement,
is that often a "line" ends a word or two before the end of a
sentence, or includes a word or two of a new sentence. I suspect that
quit a bit of thought must have gone into this, but I haven't found
any details yet.

I would really appreciate if somebody could explain why "lines" end at
arbitrary positions in sentences, and are not done a bit more flexibly
so that they more often end at the end of a sentence.

If this has been discussed already, I would appreciate pointers. Also
if there's some scientific paper about the issue.

I have tried to think about why things are as described above, and
have come up with various possible reasons. If any of these reasons
applies, please just tell me.

- There is already a setting/add-on for this, just use it.

- Having more variable line lengths would make it more difficult to read
Web pages (e.g. because the intervals between the presses of the down
arrow would be more irregular). If that's the case, then I haven't yet
had enough practice to notice it.

- Finding better positions to split text into lines is a much harder
problem than it looks. It is difficult to find actual sentence
boundaries in text (not all periods are sentence endings), and
long sentences without punctuation are also difficult to split.

- Finding better positions to split is possible, but good algorithms
are too slow. Text-to-speech conversion already uses quite a bit
of processing power.

- Finding sentence boundaries is quit language dependent, and therefore
difficult to implement in a general way.

- The overall architecture of NVDA (and other screen readers) makes
it too difficult to implement such a feature.

- Some other screen readers already do a better job at this, but we
at NVDA just have not had time to get around to do something here.
Help is appreciated. (I might want to help.)

- That's how screen readers always have done it, and everybody is
used to it, and so changing it isn't a good idea.

If there are any other actual or potential reasons, please tell me.

Many thanks in advance for your help.

Re: More flexible line length in browsing mode

Martin J. Dürst <duerst@...>
 

Hello Gene,

Many thanks for your mail. We want to try and find out whether there is a difference between various ways of reading text (fixed one-hundred characters or somewhat more flexible). Of course, if there's a link, and NVDA is set to read that separately, I guess we will read that separately.

Regards, Martin.

Re: Rearrange Pinned Items

 

For rearranging pinned items on the taskbar I really recommend using the mouse with left click and drag even if you cannot see, after you've routed the mouse to the screen reader object.  Though things can be dragged in to the taskbar from the desktop to create a pinned item, the reverse is not true.  Pinned items in the taskbar can only be removed or moved left and right relative to each other.

Though you may have to give it a couple of tries to get a sense of how far your mouse moves in the taskbar relative to how far you've moved it left/right with the left mouse button held, you can safely practice moving these icons around, checking their order, and lather, rinse, repeat until you've got the order you want.

Though drag and drop with unconstrained 4-directional movement and movement in and out of windows with focus is an absolute nightmare for a blind user, bidirectional constrained movement within something like the taskbar is significantly easier and practice does make perfect, or something near to it.

This is one of those rare times when actually using the mouse fully as intended works because of exactly what you're trying to do and the inability to drag something out of the taskbar.  But it does take some playing around, as mouse movement speed and the like can vary from computer to computer.

accessible way of moving playlists to folders in spotify?

Orhan Deniz
 

Hello there,

I'm aware that drag+drop in browse mode rarely works. Has anyone however found a way to move playlists to designated folders in spotify? As a bit of a dj its important for me to have stuff filed properly and currently what I have to do is create a new playlist in the folder, copy the old playlist, then delete it. Needless to say this is cumbersome when in theory I should be able to just move them. But of course, cut+paste commands only work within playlists, not to move playlists to folders.


Best,

Orhan.


Re: Is the Windows 10 (and, I'd presume, 11) Sandbox Feature Accessible?

 

Hi,

Regarding keyboard shortcuts, it will feel like logging onto a Remote Desktop session - you would press Control+Alt+Break (Pause) key to switch between host (the computer you are using) and guest (sandboxed environment). The way I run NVDA (or for that matter, any screen reader other than Narrator) inside Windows Sandbox is:

  1. On the host computer, prepare the screen reader files - NVDA installer or a portable copy of NVDA.
  2. Copy the screen reader file(s) to the clipboard.
  3. Go to Windows Sandbox and switch to the guest environment.
  4. Open a folder location (say, Documents). The easiest way is typing the name of the folder from Run dialog.
  5. When the desired folder opens in the guest environment, paste the just copied scren reader file(s).
  6. Because it will take time for files to be copied (especially if you are copying a folder containing portable NVDA files), switch out of sandboxed environment, then use Windows OCR (NVDA+R) to recognize what Windows Sandbox is displaying.
  7. Once the copy operation is complete, switch back to the sandboxed environment, locate NVDA executable and run it.

You can also do all these with Narrator on - just before opening the folder in the guest environment (just after performing step 3), press Control+Windows+Enter while switched to the guest environment to start Narrator inside the sandbox. When NVDA starts, close Narrator.

I belive Windows Sandbox was covered somewhat on WinAccess forum (may need to check the archive for that one).

Cheers,

Joseph

Lukasz,

That was very helpful indeed.

I doubt that anything more could be said about how one goes about gaining accessibility inside Windows Sandbox.  I don't use it, and it is clearly a VM-ish sort of environment, but it behaves even more like a true VM than I had suspected.  It appears you get a perfectly "clean slate" on invocation and must do any necessary setup each time.

Since it is a separate Windows instance it is necessary to start a
screen reader inside Sandbox so first Narrator with an appropriate key
combination and then if desired you can install NVDA as you would on a
fresh installation of Windows.
