Just forwarding an email that I wrote to AccessibleImage list when Prof.
Baldwin wrote about his program. Had questions and etc.
-------- Opprinnelig melding --------
Dear Professor Baldwin,
Congratulations!!! This is wonderful and long waited for. This is indeed
I am looking forward to trying your program and am sure many others will
be also will eagerly be doing so.
Perhaps you might consider informing the DIAGRAM Project about your tool
since they are working towards incorporation
of graphic contents for talking books.
I think you are pretty correct in saying that there is no existing
program free program for the blind and visually impaired
to draw pictures. The Talking Tactile Tablet from Touch Graphics, comes
close. It is a tool that lets a blind person draw from
a touch sensitive screen, it is not free though.
I'm sure you will be getting a long list of wish items /questions, even
before your program has been tried (hey it's 3 am here and am going to
wait a few more hours before trying) and here's a few from me:
1. Is there a library and naming possibility - that is after one has
drawn a figure one can give it a name and then have the figure
redrawn- say within another? Can you embed a SVG within a SVG?
2. Is there a grid command? Would be useful for checking if figure is in
the position wanted and for drawing. One could draw on the grid first
(using a WikkiStix for example) and then enter the coordinates
afterwards to draw the SVG. Would be useful for others that wanted to
draw with this and not just in STEM courses
3. Will this emboss directly to a Juliet, Index Express etc? As a SVG I
would see that it would to a ViewPlus embosser but what about the
embossers? Does one create a .Brl file? You write
"As a teacher, it is up to you to connect your blind and visually
impaired students to those available hardware embossing resources."
I am not sure, but one cannot emboss an SVG out from other embossers
than the ViewPlus embossers. To emboss drawings from these there are
other tools, QuickTac (free) and PictureBraille - but one needs to be
sighted to use them.With Quicktac, if one converted the SVG to a .bmp
and then saved it in QuickTac's fill file one could open it in QuickTac
and then emboss it (but need to be sighted).
4. Have you considered XMLForm? Thinking that it would be an easier
5. You mention a printer as output - are you thinking the use of Swell
paper as the embossed medium?
6. Have you thought to contact produsers of embossers? They might be
interested in expanding their product. ViewPlus? Index has a drawing
program for it's embossers and I think FreedomScientific many years back
also had a drawing program. Duxburry gives Quicktac for free - so they
are also interested in tactiles.
Will be sending your message on.
Thank you. Your work is very exciting and it is a breakthrough! For a
long time I have been looking for a drawing program for the visually
impaired. I believe for a visually impaired person that being able to
create drawings oneself is a great help in being able to understand and
interpret tactile graphics. Doing it oneself gives one a greater
