[orca-list] Sound icons__was: Is Orca support plug-in architecture ?

I am still of a mixed opinion re building ESpeak in to the screenreader. I think it is a good thing for 
NVDA/Windows as 
there are so many public computers running that OS, thus the need to be able to access them exists for many, 
including 
myself on rare occasions. Who has a public Linux box in their neihborhood? Some schools certainly do, but in 
those 
situations it's best to install speakup and Orca on some or all of them if there's any need, and of course 
the underlying 
accessibility stack that will usually include espeak. As for the progress beeps I;'m very much in favor of 
this, and one 
would think that this should not be hard to implement in Orca. I also like the other sound icon proposal, 
focus/browse 
mode switching sounds. A tone can prsent the information faster, i.e. with less interruption than words. This 
is the blind 
man's equivalent of a picture being worth a thousand words. A tone that uses frequency in both senses, i.e. 
lower or 
higher and the frequency which it is played, (interval between tones in other words), can last a tenth of a 
second and is 
worth two two syllible words. How many of us can actually listen/understand synth speech at 2X10X60, or in 
other words 
1200 words per minute? Even if the tone lasts twice that long it is less intrusive to me and I think a 
majority of users 
than the words. I can hear the tone with out interupting my voice stream and process the information no 
problem. Words are 
a bit more distractiing, and I suspect require more processing by the brain than would a good sound icon, but 
I have no 
real evidence of this, more of a guess/ hypothesis that is probably worth some body testing in some 
university. And 
although many of us do listen at 600 wpm or higher, the vast majority do not as they are not hacking there 
systems to do 
so, and default top voice rate is 450 WPM now I think for espeak with Orca or speakup. Even a relatively slow 
listener can 
process the mode switch or progress update information at a wpm equivalent of 600WPM or perhaps double this 
with out 
breaking a mental sweat, where as they may be listening at 250 or 350 WPM to process textualy transmitted 
data. 
Seems a no brainer unless there is some technical hurdle I can;'t think of. 
Another thought along these lines is how about a sound icon to tell us when switching from carrot browsing on 
to off and 
visa versa. 
I keep the ask if I really want to turn it on message around because I often have no idea which mode I'm in, 
and this way 
I can keep track of it. 
A tone to let me know which mode I'm switching in to wold save me a keystroke and lisstening time as well. 
Are there any other instances where sound icons might be of value, perhaps, but too many could be counter 
productive for 
some, and I really do not see any other place that Orca should logically use them. 
None of these things have anything to do with a potential plug-in archetecture, and in case some were 
thinking it, I 
really doubt that a univrsal system could be easily created so that NVDA and Orca could interchange these, 
even if it were 
designed from scratch, an I'd bet a good part  of what I do not have on this being some where between 
incredibly 
impractical and impossible when it comes to using what exists for NVDA currently.

hi
Beeping on progress bar updates, possibly that little click thing it
does when entering and exiting form fields, probably more accurately
said as when it enters and exits focus/browse mode, and a builtin espeak.
That's my two cents

It will very useful that orca will support plugin feature i.e
add-ons , so it will possible that we can add NVDA's plugins in
orca if possible, so it will enhance Orca's power , feature
support list . so if we have to make orca support for plugin
architecture, what changes need to do in orca, it will affects
orca's architecture ?


Ok, lets look at this another way. What functionality would you
like in Orca that NVDA has?
