[Nfb-science] Hello

[Salisbury, Justin Mark]

I think there are plenty of ways to make 3-D models that you can feel to understand, but a flat, 2-D drawing with raised lines will be quite difficult.  3-D models are often better for sighted students, too, so perhaps it will help you to pitch it to your teachers so that they understand that these models will be better for everyone and ask them to construct such models.  They may just say yes.

A drawing representing three dimensions is an optical illusion.  The key word here being optical.  I don't think it is possible to create a three d tactical allusion.  No matter how you arrange the lines they will still feel two d.

Hello,
    This tactile graphics is an issue that keeps coming up.  As a sighted
person, and a "science person" who has transcribed science/math materials as
well as tutored some blind students, I believe that the tactile graphics are
fine if use with an educated reader who can clearly explain what you are
feeling.  I think too often the graphic looks good to a sighted person, and
yet is misleading to someone who doesn't see.  Also, since some people with
visual impairment see well enough to have images enlarged on the computer,
it is only a subset of the blind community who truly relies on tactile
images.  I would like to see if we can have educated individuals who can
give a verbal description that accompanies tactile images/materials.  I have
repeated seen blind individuals not have the same understanding of a graphic
image as sighted ones.  This is just based on the "snap shot" view that a
sighted indivual has that is not duplicated when you are feeling the whole
image.  Simple verbal descriptions that give an understanding of what the
"larger picture is" and possible 3D models rather than images would be a
great improvement. I have been trying to encourage educators of this
approach, but they complain about the costs and state this is how it has
always been done.  If anyone on the list agrees and have an ideas on how we
could make this improvement, I believe that is would help many.
