Trust me it does not extend the battery of any i device.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.

Re: Screen Shade/curtain?
Hi,
toggle quoted messageShow quoted text
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

Inaccessible web sites
Rick
Hello NVDA community members:
Next month, I will be working with human resources in the company that I work for, promoting web accessibility for our internal web-based tools. Initially, I will introduce them to the importance of alt text and keyboard navigation. These are areas they can experience poor behavior without using a screen reader. Please send me links to any web sites that you are aware of that are not navigable or hard to navigate using the keyboard (or exhibits keyboard lock behavior) and /or sites with no alt text.
Thanks in advance and happy holidays.
Rick

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. Cheers,

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.

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. Brian bglists@blueyonder.co.uk Sent via blueyonder.

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!
