There is software available on the Net for 3-D printing of math expressions encoded in LaTex. What such technology is available off-the-shelf for the visually impaired to learn mathematics? And, accompanying research/anecdotes on its effectiveness?

  • $\begingroup$ I'm trying to understand, when you ask about "what such technology", how closely related to 3D-printed formulas you're looking for the answers to fall. Are you interested specifically in 3D-printed formulas, or in printing other objects in lieu of visualizations, or are you talking about haptic learning aids in general? $\endgroup$

    $\begingroup$ @forritari: I meant to target the question for 3-D printing of mathematical expressions for the blind, but if you can link to other AT for learning math for the visually impaired, please do (reconfigurable pins, e.g.). (Would make a great project for team of math/engineering/CS majors.) It would also be beneficial to understand the differences in effectiveness of haptic aids and aural aids. $\endgroup$ Commented Mar 13, 2015 at 5:01
  • $\begingroup$ For problems in planar geometry, one blind student I knew of used rubber bands and pins on a board to assist her understanding. $\endgroup$ Commented Sep 13, 2022 at 13:38
