As far as I know you can't just turn off the screen
in the Windows settings and doing so may cause you real trouble if you can do
it. If you unexpectedly need sighted assistance, to deal with some sort of
maintenance or performance problem, the screen should be on.
The screen shade has the advantage that the screen
is still on and a sighted person can work with the machine if
needed.

Subject: Re: [nvda] Screen Shade/curtain?
I agree that we should only have features in screen readers
that many people will really need, and will help them do a job. Many features in
some screen readers are just not needed. You do not need a feature to do
searches for you, when you can do a Google search. You don’t need this screen
shade, because you can just turn off your screen in the Windows settings.
I really don’t know why anyone needs screen shade.
It is a useless feature, I think. How important is that for
someone to be employed. We need screen readers to help people work many jobs,
that should be the first importance. Next, intertainment uses need to be
accessible with a screen reader. If you work hard, you need to play hard
LOL!
NVDA does not have to have every feature that JAWS has
either. I am so glad it doesn’t.
It takes me a few seconds to install NVDA, and 15 minutes to
install JAWS, and JAWS leaves footprints all over my computer.

Hi
I agree with Joseph.
There might be things from other screen readers we might use or might not use
so I would rather the developers concentrate on screen reader features that
help.
if some one has got the smarts they can do it in a add on and that way if one
is made you have the choice of either adding it or not.
then down the track it could be added like you see with some addons that code
gets added to the core of nvda.

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

it does not work on my

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 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, 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

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

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.

Screen Shade/curtain?
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!
