A children’s classic that already is a candidate for the all-time best feel-good book, “Goodnight Moon,” has gotten a boost: A team from the University of Colorado Boulder team printed the first 3D version of it, allowing visually impaired children and their families to touch objects in the story. In fact, more than 40 million copies has been printed and translated into dozen languages. Tom Yeh, a computer science professor at the university – started the Tactile Picture Books Project to create customized solutions for young readers whose needs aren’t met by conventional publishing methods. The books were created using computer algorithms and the vision of the design team.The idea of tactile picture books is not new, but making 3D printing more accessible and interactive to the parents and teachers is new. And numerous highly popular children’s books are in the same process.
