3D Printed Tactile Blissymbols
Volksswitch.org has created a next generation of tactile symbols based on Blissymbolics to teach language to individuals who are blind, deaf-blind, or visually impaired. The symbols may also be effective when used with individuals on the autism spectrum. These Bliss Tactile Symbols are opensource, customizable, extensible, and designed to be 3D-printed.
