Researchers at the University of Colorado Boulder have designed a series of children’s books for the visually impaired.
U-Boulder’s Tactile Picture Books Project uses 3D printing technology to turn classic children’s books including Margaret Wise Brown’s Goodnight Moon and Harold and Crockett Johnson’s Harold and the Purple Crayon into books with three dimensional tactile experiences.
Colorado.edu has more: “The main idea is to represent 2D graphics in a 3D, tactile way on a scale appropriate for the cognitive abilities and interests of young children, said Yeh. The team combines this information with computational algorithms — essentially step-by-step instructions for mathematical calculations — providing an interface that allows parents, teachers and supporters to print their own customized picture books using 3D computers.” (Via Electric Literature).
