[accessibleimage] Re: Accessible graphics programming using Logo and The vOICe

P.S
One point more, once you make a Logo graphic, embosses out very nicely with Tiger. And to think of it, haven't tried it, but opening the graphic in say PictureBraille etc, could than make it suitable for other embossers.- Best,

Hi Peter,
I LOVE turtle graphics and the whole idea behind Logo. It's purpose was
to introduce children to the concepts of programing. Very intuitive.
I have often wondered if this would be a good technique for drawing for
blind people. It works with writing directions - ahead 10, turn left,
ahead 10 etc.
It was started at MIT by Seymour Papert http://papert.org/ resulting in
a "philosophy" called, if I remember correctly, functionalism.
Lego based it's Mindstorm kits on it. That is a kit for making robots.
There has been done some work by a MIT student some years back to make
that system accessible for low-vision users. Unsure if I posted that on
the list or not -if interested drop me a line and will send.
A great book to read about it's use in a school situation is Children
Designers by Idit Harel

To change the subject but stay on the same subject, I also wonder if SVG
would also be a useful tool for drawing for VI people. That is one uses
text to draw.  Similar, in that you write to define a form,  to Logo. It
is not very difficult to hand code - what do you think?
It is wonderful that you have this on your site Peter and for blind users!!! 

Best,
Lisa
