Re: Next version of noughtsAndCrosses - adding a (simple) form of narration to a webpage itsself

Ok, I'll have to pass that on, since the way it's hosted at the moment, you 
won't see anything apart from the standard HTML tags, linking to external 
script source files, and, again, the one real one, with the actual 
implementation script in it is hidden by a PHP session variable check.

Firstly, the two sort of script libraries I am making use of are, JQuery 
(simpler/clean access point for a version/implementation of DHTML):
http://jquery.org/

and, SoundManager, which implements the embedded flash object to handle the 
sound playback etc.:
http://www.schillmania.com/content/projects/soundmanager2/

Then, there's around 360 lines of javascript, handling everything from 
initialising the objects containing/wrapped around the sounds, attaching event 
handler functions to the objects on the page - using basic javascript syntax, 
but approaching it a bit other than normal, along the lines of the JQuery 
methods/approach, etc., and if you want, I can try post some of that again, 
etc., since the only real change have made this time around is to in fact 
handle a sort of queueing of sound playback, using an array to store the 
identifiers of the sound objects to be played, one after the other, and all I 
did extra there was add a bit of a check to the onFinish event of the sound 
objects to then check if another sound in fact needs to be played, and if so, 
to then play it, etc.

My theory is that javascript, PHP and C# are relatively similar in terms of 
basic syntax, but they all have each of their own peculiarities, etc., and this 
then gets a slight add-on from using JQuery (unless I'm just not used to really 
taking javascript to this full level or something), and the only other 'funny' 
thing about javascript is that along the lines of defining a variable inside a 
method/function in other languages, and not having it available to other parts 
of the whole overall structure, variables generally defined within a script 
block <script...></script> are to a certain extent limited to being seen 
therein, but the DOM (document object model), with the window object sort of at 
the top of it, can be seen/accessed from all around, etc. - and this is all 
just my sort of general version of an explanation of my version of an 
understanding of javascript, etc.

Stay well

  This is very interesting.

  While I don't have a lot of knowledge or experience with HTML and the various 
scripting I am looking forward to looking at the source in detail when I get 
some time.

  Very clever.

    The voice is scansoft/realspeak daniel, but I did output/render the clips 
at quite a fast speaking rate to partly try drop their file size/running time, 
and I also dropped them to 24kbps (kilobits per second) to make all 10 of them 
that might get used amount to a total of 14kb, and the idea with the embedded 
flash object preloading them is that they get sort of cached at load time, 
instead of needing to be reloaded/refreshed each time they need to get played, 
etc., and it seems to me like they do each sort of play a bit quicker from 
their 2nd time onwards, but, yes, it's not 100% real time as such either way.

    I was also testing/trying out catching actual keystrokes via the 
document/webpage itsself for navigation etc., but you would then need to turn 
off things like jaws since it's catching of the navigational keystrokes for 
it's virtual buffer block the javascript DOM from noticing them as 
such...<smile>

      Ah!

      That works more like it.

      Cool. I have a little trouble with the voice, a little difficult to hear 
particularly over Jaws but without Jaws it would probably be better.

      I am guessing that with dial-up the delay would be unacceptable but here 
it isn't much.

      Very clever.

        You will at this stage need to tab onto the buttons to in fact focus 
windows on them as such since just normally moving around in the screen reader 
virtual viewer doesn't really focus on them as far as javascript is concerned.

        If you are using jaws, and you route jaws to virtual cursor, it should 
also speak since I have also attached the playing of the relevant sound clips 
to the mouse cursor hover event, but anyway.

        Thanks for trying it out...<smile>

        Stay well

          Hi Jacob,

          When I press space on a location I do hear "knot" but moving around I 
get nothing else. If I space on a button I have already checked I hear sorry 
but I don't hear the state of the button when landing on it. I take it I should?

          The delay isn't bad, an interesting approach.

          Cool.

          Dale Leavens.

            http://www.blindza.co.za/noughtsAndCrosses/

            There should now be a form of narration in that when you focus on 
one of the buttons, or even hover a mouse cursor over it, you should hear the 
narrative sound clips, etc.

            Issue is still something to do with preload timeframes etc., since 
even though the sound clips are pretty small/tiny, it still pauses a bit, but 
anyway...

            Stay well
