Hi,
VoiceOver has had screen curtain feature for a long while and JAWS recently got screen shade.
Does NVDA have a similar feature via an add-on or natively? Thanks!

Hi, Not yet, with a GitHub issue created to talk about this. I have some opinions about it, but won’t go there yet. Cheers, Joseph

Hi, I remember that GitHub post, as long as I read about pithon language, it does not allow us to do anything with the display, anyways, I glad to hear that Joseph has some idea about screen shaid, because I also need an addon like this, now jaws has this feature, and I’m waiting to use this feature in NVDA, please someone creat it regards, Abdulmuhamin Yousaf! head of content department at www.blindHelp.net

I think an addon to dim the screen would be nice. Does anyone
know if an external program exists to dim the screen?

From what I know about Windows and indeed most screenreaders, this function is just for privacy, ie its not going to save any battery. If that is what you want then I'd have thought it was possible to do it, kind of like a screensaver that never actually loses focus but then you need to be able to tell nvda that you want it to use the invisible window not the visible one.
In the issues tracker there is a thread on this. Also the ultimate way |of doing this on a desktop is called the monitor off switch..... ahem.

Monitors normally have one as do most laptops. However to me if its not going to do much for the battery then really all you need is to make it black from anyone hanging around point of view.
People tell me that many folk are very lax, even getting up in a library leaving the sscreen on with their personal data on it.

For what it's worth, I like this idea as far as privacy is conserned. If it isn't intigrated into nvda, then perhaps a member of the community can write an addon/standalone application? Just my thoughts.

Hi all,
I am not sure what this functionality is exactly about.
When it is about switching off / dimming the monitor, I do not understand why it would not save on battery....
The backlight of a monitor in a laptop, tablet, smartphone, ... whatever is one of the main power sinks in such systems.
On a laptop, you can often (this may vary between laptops) use Fn+f7 for switching between different display modes (signal send only to laptop monitor, signal send to external monitor only or signal send to both) or Fn+F5 to dim the backlight and Fn+F6 to light it up.When I am on battery power for a long time, I dim the backlight with Fn+f5 to save battery.
Thus you don't need a NVDA add-on for that, although such add-on may be useful to read the status of the screen (to which monitor is the signal send, on what level is the backlight). I have no clue whether windows has access to such info, let alone it provides an api to request that info (it might be the case that on some laptops this is a pure BIOS feature completely transparent to windows).
Once again, I am not sure what this functionality is supposed to be exactly, and thus I may be speaking about something completely different.
Kind regards,
Didier

Actually if you look on the screen brightness thing on ios or android it does bring the brightness all the way down to 0 so yes it does in effect shut off the display. I've seen my batery actually be extended this way.

Trust me it does not extend the battery of any i device. Now the purpose of screen shade is say you are in a work inviroment and you don't want people looking over your shoulder. Makes since.

Hi, As noted by some members, screen shade/curtain shows what appears to be a blank screen. This is used to "guarantee" privacy for screen reader users. Note the quotation marks around "guarantee", as it does not really guarantee privacy, as there are means to circumvent this (speech output, braille displays, remote access, etc.). From what I can gather, this function does not result in extended battery life nor power savings. When this function is turned on, an overlay window is imposed on top of other windows, and turning this off removes this overlay. As I said above, this does not provide privacy as many of you may think. As for this being part of a screen reader: my overall opinion is that it should not. If people want it, then I think an add-on would be a more appropriate solution. Only after looking at justifications and costs should developers consider adding this into NVDA, in my opinion, and personally for me, a justification that goes along the lines of, "because another screen reader has this" is something I won't even consider. Cheers, Joseph

This statement is based on what? 1) It is my experience it does extend the time you can do on a battery charge as I mentioned previously. 2) I just checked the battery usage on my android smartphone: 31% went to the screen, which is the winner. As it is a phone, the screen is relatively small: roughly speaking 4x the size of a laptop screen --> the powr usage of a laptop screen would thus be 4x higher. 3) Given my electrical engineering background, it makes perfectly sense to me the backlight of a screen is one of the most power hungry components in a laptop/tablet/smartphone. 4) Together with my father I repaired a couple of years ago the powr supply of the backlight (switching power supply transforming the 5Volt into something like 400Volt)of an external LCD monitor: everything in this monitor consists of minituraized SMD components, except this part that is built with large discrete components, indicating the backlight is not at all low power (otherwise they would not opt for such costly approach). 4) The backlight of a screen is one of the few components that is constantly consuming power (at the rate of the duty cycle, representing the dim level), while other periphery have a more intermittent power profile (you are not constantly transmitting data with your wireless interfaces, speakers are not constantly driven, most of the time the cpu is underutilized letting it switch down the clock frequency is mobile devices to save energy, etc). Now the purpose of screen shade is say you are in a work inviroment and you don't want people looking over your shoulder. Makes since.

Hi Joseeph,
Thanks for the clarification.
Indeed, showing a blank window would not save energy. But why not simply switching off the screen (power button on an external monitor, or using the Fn+F7 (or similar key combination) on a laptop? Then you have both advantages, the pseudo "privacy" thing, and the energy saving.
I agree with the rest.
If an add-on would be needed, then I believe it is more worth investing in an add-on that can report the status of the screen (backlight level, to what port/screen the video signal is send), a bit like the battery level feature in NVDA (nvda+shift+b)
Kind Regards,
Didier

Hi,
VoiceOver has had screen curtain feature for a long while and JAWS recently got screen shade.
Does NVDA have a similar feature via an add-on or natively? Thanks!

Hi, Sure, turning off the monitor may work, but not always. Cheers, Joseph

Hi all,
I am not sure what this functionality is exactly about.
When it is about switching off / dimming the monitor, I do not understand why it would not save on battery....
The backlight of a monitor in a laptop, tablet, smartphone, ... whatever is one of the main power sinks in such systems.
On a laptop, you can often (this may vary between laptops) use Fn+f7 for switching between different display modes (signal send only to laptop monitor, signal send to external monitor only or signal send to both) or Fn+F5 to dim the backlight and Fn+F6 to light it up.When I am on Fn+battery power for a long time, I dim the backlight with Fn+f5 to save battery.
Thus you don't need a NVDA add-on for that, although such add-on may be useful to read the status of the screen (to which monitor is the signal send, on what level is the backlight). I have no clue whether windows has access to such info, let alone it provides an api to request that info (it might be the case that on some laptops this is a pure BIOS feature completely transparent to windows).
Once again, I am not sure what this functionality is supposed to be exactly, and thus I may be speaking about something completely different.
Kind regards,
Didier

We ended up making our own via a physical solution of a black sheet and velcro, which is betwither than screen protectors I've tried, it's true privacy, and can be removed on-demand if I need to show someone something.

it does not work on my 2 all in ones and I tried a little program on my laptops that should do this but it didn't work. I think it should be in nvda and Joseph for you just to say that you won't consider it if people say other screen readers have it is very heavy handed.

Hi, Some JAWS users did report that it doesn’t work all the time. As for my justification statement: like some in the community, I believe that NVDA's purpose is screen reading. I think NVDA Core should focus on screen reading, with add-ons coming in with optional features. I do understand that I can be heavy-handed at times like the one pointed out below, but I'm speaking from experience that just following the lead of another screen reader just because NVDA should is something I'm uncomfortable with. Also, privacy is something a shade feature cannot guarantee 100 percent, as there are numerous ways of breaching it, including sounds, speech, remote access, data sharing and many others. Cheers, Joseph

There are so many things that screen reader developers are facing right now that impact our access to the internet that it seems time would be best spent there. At. Though I have not tried them, there seem to be a number of apps that are designed to let one turn off or dim a laptop screen. Quick search turned up Screen Off at: http://www.thewindowsclub.com/screenoff-turn-off-windows-laptop-screen

Hi,
VoiceOver has had screen curtain feature for a long while and JAWS recently got screen shade.
Does NVDA have a similar feature via an add-on or natively? Thanks!
Not at my laptop or I would give this a try. Maybe sharing the names of apps that work or don't work could be a shared effort here. Rick
