Re: OCR: Interacting with items from recognized UI

You can use normal mouse control functions in NVDA to do this. See section 5.7. Navigating with the Mouse of the NVDA user guide.


OCR: Interacting with items from recognized UI

Luke Robinett <blindgroupsluke@...>
 

Hi,

 

For inaccessible UIs I’ll often run NVDA OCR on the UI and then press enter or space bar on the UI controls I find in the recognized text such as tabs, menus and buttons. I find this only works in some programs and other times seems to be ignored. I believe the issue in some cases is that some UIs only respond when an actual mouse is clicked on a control. Is there a way to have the mouse cursor move to the UI element corresponding with its label in the OCR viewer and produce a click on that element? If not, is this something I could submit on GitHub as a feature request? It would make the already helpful OCR feature even more useful.

 

Thanks,

Luke

 


Re: control click with nvda?

 

Might I ask several questions:

1.  What, precisely, are you actually attempting to do with CTRL+Click in this instance?

2.  Are you using a desktop?  If so, have you ever considered using a "hobbled mouse" that would allow you to use its buttons while eliminating the pointer movement?

3.  Are you using a laptop, where you likely have direct access to left click already, and could use CTRL+LeftClick without emulation?

Re: Double Tone

 

As a former programmer, I hesitate to even suggest the following, as it is likely far, far more complicated than the previous descriptions lead me to believe it might be.

But if NVDA is detecting that an error has occurred, and what would be sent to the NVDA developers (or add-on developers), and all of that content comes from the log file working backward from current logged error to the last one to extract what's needed, could this not be automated as a function (or, perhaps) add-on for the beta itself?

Based on what's been described, which I understand may not be comprehensive, grabbing that traceback should be relatively straightforward programatically and would result in far more data for developers than relying on manual reporting would.

[Now, let the explanations about why the above is, in actuality, impractical, begin.  It just can't be this straightforward or someone would have done it.]

Re: Double Tone

 

Hi,

Typical errors can include, but are not limited to:

  • Python specific errors such as inability to load a module, syntax errors with either NVDA or an add-on, errors associated with data structures such as key/index/value error exceptions, resource error such as inability to open a URL.
  • Errors from external modules, either wxWidgets/wxPython or something else.
  • Recently, garbage handler messages while managing resources.

When an error tone is heard, as Tyler noted, pressing NVDA+F1 will open the log viewer, from where you can scroll up to read the last error associated with the tone (technically a traceback). We (developers) need the complete traceback from the last error to determine what’s going on so we can either resolve it from NVDA side or reported to add-on authors (in case of my add-ons, I can guarantee a fix in minutes once I identify a possible cause and test a fix live; I use alpha builds for this purpose, and I try my best to make my add-ons error-free as much as possible before NVDA betas are released).

Cheers,

joseph

I really wish I knew "what sort of error."  Ninety-nine times out of one hundred I can see absolutely no difference from typical behavior, so it's unclear what's been identified as being off.

Re: Double Tone

 

Hi,

Specifically, to help you report bugs to developers easily, as these tones indicate some sort of error.

Cheers,

You've actually answered your own question, kinda, sorta.  The only time I have had those double-tones is when I'm running a beta version, once something goes to the release candidate or actual release version those disappear.

I have to believe this is an intentional design element so that one knows that a beta is in use.

Re: Double Tone

The tones indicate an error of some sort. The tones are enabled on betas so users are aware of when errors occur. They are disabled in production releases. Most of the time, such program errors don't affect the functioning of the program.

That's the error tone. If you look in the log viewer after it plays, you'll see what happened.

Tony's add-ons: new and updated

Tony Malykh
 

Hello all,

This is Tony, author of many NVDA add-ons. During holidays I updated many of my add-ons, and wrote two new add-ons, so I would like to share them with you guys. This is a long email, so please feel free to navigate by headings!

Please note that links on the official website have not been updated, as it seems that nobody has access to that website anymore. Therefore, please download directly from Github, download links included below.

 

New add-ons:

WordNav

It takes word navigation to the next level in NVDA. It standardizes what exactly does word mean, e.g. does it include punctuation before and after, moreover, it offers various definitions of word, some of which might be useful for software developers, for example when they are working with camelCaseIdentifiers. It redefines Control+Left/Right keystrokes, as well as it adds optional Control+Windows+Left/Right keystrokes. Configuration panel included!

·       Github: https://github.com/mltony/nvda-word-nav/

·       Download: https://github.com/mltony/nvda-word-nav/releases/download/v1.2/wordNav-1.2.nvda-addon

 

Console toolkit

This is a collection of tools for heavy console users. Among its features are:

·       More realtime speaking of console output

·       * Beep on update

·       Control+V shortcut now works in ssh connections

·       Editing of current prompt in accessible window

·       Capturing command output, including multi-page, and displaying it in an accessible window

 

Please note, it supports the default Windows console, a.k.a. command prompt, as well as windows PowerShell.

·       Github: https://github.com/mltony/nvda-console-toolkit/

·       Download: https://github.com/mltony/nvda-console-toolkit/releases/download/v0.2dev/consoleToolkit-0.2dev.nvda-addon

 

Updates

SentenceNav

This add-on allows to read text sentence by sentence using Alt+Up/Down keystroke. I managed to improve its performance a lot, now it reads sentences much faster, especially in large paragraphs. I also added experimental support for Microsoft Word and WordPad – before this version built-in NVDA logic applied to sentence navigation in these programs, and many users have complained about that. Also, a number of bugfixes. Also I wrote extensive documentation, since sentence finding code has become so complicated, even I myself is having a hard time reading my own code after a couple of years since first release 😊

·       Github: https://github.com/mltony/nvda-sentence-nav/

·       Download: https://github.com/mltony/nvda-sentence-nav/releases/download/v2.9/SentenceNav-2.9.nvda-addon

BrowserNav

BrowserNav contains a set of improvements to browse mode in NVDA. Besides a number of bugfixes, this new version includes command to jump to next text written in different style (bound to tilde, that weird key right above Tab), and a command to scroll down to reveal all the hidden content, bound to backslash. That last command might be useful for websites, that load content dynamically. This includes Youtube, that doesn’t load the entire page and expects users to scroll down to reveal certain elements, and also so called infinite scroll webpages, such as Amazon and Facebook.

·       Download: https://github.com/mltony/nvda-browser-nav/releases/download/v1.12/browsernav-1.12.nvda-addon

Tony’s enhancements

This add-on is an incubator for my experimental ideas, yet I believe many of them might be quite handy for many users. In particular, this time WordNav and Console toolkit mentioned above have graduated from this incubator. 😊 Among new features that I added are QuickSearch command, that allows to quickly find predefined text or regular expression in text files. I personally find it useful for editing markdown, because you can set the regular expression to search for next/previous heading, and also for programming. Another new feature allows to set system priority for NVDA process – this might improve responsiveness of NVDA, especially when CPU load is high.

Other

NVDA Symbols

This is not an add-on, but rather a comprehensive (more or less) table of unicode characters with their proper English names. In particular, it includes math symbols (the ones that are not defined in NVDA), Greek letters, technical symbols, various arrows, etc. If you’re Greek, you would probably want to exclude Greek letters from this dictionary. If you speak CJK languages, you would probably want to exclude fixed-width punctuation page from that dictionary. This table would need to be added manually to your symbols.dic file in NVDA user config directory.

Let me know what you think!

tablet question

Charlotte
 

Hello. I am considering purchasing a Windows tablet. I have a desktop PC but with my small business it would be great to be able to use the Windows platform that I am familiar with when I am out and about versus having to manipulate apps on my phone. Can anyone recommend a Windows tablet that supports NVDA and has a decent amount of ram and processing power? Any info is appreciated. Thanks.

Re: beta 3 and closing programs (Using Powershell)

 

Just FYI, just like you can create command prompt scripts in batch files, that are simply text files that have the extension .bat, you can do the same for PowerShell commands.  The extension for a PowerShell batch file is .ps1

If you activate either a .bat or .ps1 file, it will run.  So if you use these extensions, and want to edit the file later, you must gain focus on it, bring up the context menu, and choose Edit from it.

I've seen people (including myself) get burned by double-clicking/activating .bat or .ps1 files because doing either of those things for most other file extensions will open the editor for same.  Not so for these two.

Re: Reducing the reading speed of NVDA

 

Before I answer your question, I want to make you aware of one of the handiest commands for a new NVDA user when it comes to finding the keyboard shortcuts used to control the vast majority of "commonly used" features:   NVDA+N,H,Q  (which is INS+N,H,Q in desktop keyboard layout) will cause the Commands Quick Reference to open in your default web browser.  The question you're asking is about one of the common features/tweaks, and the keyboard shortcuts for changing the reading rate, is found there under Synth Settings Ring, copied here:

Synth settings ring

Name Desktop key Laptop key Description
Move to next synth setting NVDA+control+rightArrow NVDA+shift+control+rightArrow Moves to the next available speech setting after the current, wrapping around to the first setting again after the last
Move to previous synth setting NVDA+control+leftArrow NVDA+shift+control+leftArrow Moves to the next available speech setting before the current, wrapping around to the last setting after the first
Increment current synth setting NVDA+control+upArrow NVDA+shift+control+upArrow increases the current speech setting you are on. E.g. increases the rate, chooses the next voice, increases the volume
Decrement current synth setting NVDA+control+downArrow NVDA+shift+control+downArrow decreases the current speech setting you are on. E.g. decreases the rate, chooses the previous voice, decreases the volume

You'd have to get yourself to the speech rate for your chosen synth using one or the other of the first two commands, then increment/increase or decrement/decrease the rate using the third and fourth commands, respectively.

Open settings and go down to speech, then press tab until you here
"rate" then use your left and right arrows to adjust it to your
liking.
