Hi Sally and all,

That's an excellent point. It's important for a blind person to know
enough about how visual material is presented to be able to make
graphs, charts and posters either independently using software or by
accurately directing a reader. In my graduate career I must often
generate graphs and charts for data presentations. I don't have a
perfect idea of what these look like to sighted people, which is why I
work rather heavily with readers, but I must know enough to be able to
give them basic direction and to evaluate their work based on their
verbal descriptions of what they have produced for me. It's also
important for me to "visualize" a data set well enough to keep track
of how the rows and columns in an Excel spreadsheet are set up, even
when I am not using a Braille display. This is not hard for me, but
perhaps would have been harder if I had not been exposed to Brailled
tables and basic bar graphs while growing up. I know that if I start
teaching, I will face additional challenges in trying to generate
materials that are memorable and informative for sighted people.

Personally I find three-dimensional representations of things to be
much more helpful than graphics on paper. For example, in basic
geometry classes my TVI would give me cubes, trapezoids, etc. that I
could actually hold in my hands whenever she could. It is very hard
for me to assess the volume of a shape on paper, but much easier for
me to understand the concept of height/depth when I am holding a
physical object. Also, I learned organic chemistry by using modeling
kits to build molecules by stringing together balls that represented
atoms (and were different colors and textures for different kinds of
atoms). I had an amazing professor who would hand me these models
whenever he placed a picture on his overheads and even allowed me to
use the models on tests. Fortunately, these modeling kits were
mainstream tools for all O-chem students, so no special blindness
accommodation was needed. I suspect that using three-dimensional
representations more often would help many students, not just blind
students, but it's cheaper and easier to use a two-dimensional image
in many cases.
