ABSTRACT
We address the practical problem of automating the process
of translating figures from mathematics, science, and en-
gineering textbooks to a tactile form suitable for blind stu-
dents. The Tactile Graphics Assistant (TGA) and accompa-
nying workflow is described. Components of the TGA that
identify text and replace it with Braille use machine learning,
computational geometry, and optimization algorithms. We
followed through with the ideas in our 2005 paper by creat-
ing a more detailed workflow, translating actual images, and
analyzing the translation time. Our experience in translat-
ing more than 2,300 figures from 4 textbooks demonstrates
