[accessibleimage] Re: New to Tactile Graphics

Greetings all,

The tactile graphics produced by the Tiger are quite good. But,
unfortunately, many braille readers find the braille produced even by the 
recent Tiger embossers difficult or
annoying to read because of the relative closeness of the braille dots, 
especially in large amounts. The problem is not related to  the size of 
anyone's hands, but, to the optimum spatial configuration for
easily discerning the symbols when using the pad of one's finger, related to
average nerve sensitivity in the pad of a finger.

Best regards,

Sylvie

 Well it depends on what you mean by smaller braille.  Tiger technology 
places dots exactly 0.100 inches apart within a braille cell.  Other 
embosser range
from 0.092 to 0.100.  Spacing between braille cells is 0.250 inches 
horizontally and 0.400 inches vertically for virtually all braille embossers 
including
Tiger embossers.  I suspect that you are referring to the sharpness of 
braille that was typical of Tiger embossers a few years ago.  If the punch 
force
was set high, the dots could be sharp.  Current generation Tiger embossers 
have dots that are much less sensitive to precise punch settings.  They are
pretty much identical to all others braille dots on top but have slightly 
smaller bases in order to get 20 dots per inch when embossing graphics.  I 
do
not believe that braille readers can feel the dot base, at least not without 
trying hard, so current generation Tiger braille should certainly not feel
"small".
Hope this is helpful.

Yes, it is smaller but when I requested a sample graphic (to see if the
tiger embosser was something I want eventually), the Braille labels on the
graphic did seem smaller (to me) but no harder for me to read (I do have
small hands though).

It is my understanding that due the fineness of the embossing of the tiger
braille embossers, the braille text is a bit smaller and harder to read. Can
anyone tell me if this is true. I have never used a tiger embosser so I
don't know the quality of braille. Thanks.
Bret

Hello Bret, if you are getting a Tiger embosser, you'll get TSS with it. TSS
has a good braille translator application that lets you translate everything
in MS Word, including math, and in Excel, including Excel charts and
graphics. And you can print graphics from any standard application.

Duxbury also supports math braille from MS Word I believe, so it is no
longer necessary to use Scientific Notebook.

Hi All,
I am a Braille Transcriber with a school district, and am visually impaired.
One of our students is going to be taking an algebra/geometry class next
year. We will be required to create all of the charts, graphs, and other
graphics for the class. I am using Duxbury as my translation software and am
using a program called Scientific NoteBook to create all of the mathematical
text. I was told that there is a program that works with Duxbury called TGD
Pro which allows you to copy an image and then import it into a duxbury
file. Does anyone have any good ideas or suggestions for me on the best way
to create a tactile graphic electronically? I have limited sight, so being
able to draw or create things by hand may be out of the question. Our
district will be getting one of the new Tiger braille embossers so I think I
can create tables and charts with excel and then emboss them. Thanks for any
suggestions or advice.
Bret
