Tactonom Reader seems like an interesting multi-modal approach that is readily available: https://www.tactonom.com/en/product/tactonomreader/ https://www.tactonom.com/en/product/tactonomreader/ In general, tactile graphics is a long-standing issue. In the past, the most basic simple mechanical solution wasn't that bad. Just needs a special kind of paper and a ballpoint pen. My teachers used to hand-draw curves for me on demand, however, that was at high-school level... The more complex the solution gets, the more work/knowhow is required to prepare a particular graphic. Turnaround time gets longer, and the expertise expected from the educator gets more complex. Its questionable how many casual educators end up being able/willing to prepare graphics for/on a complex digital system...
