Last year, we reported on a project that benefited the blind. New York 3DPhotoworks used a 3D printer to print out the famous museums, so that blind people can experience them with their fingers.

But now, there are more and more attempts to enter the blind life with 3D printing technology. Recently, the University of Colorado Boulder used 3D printing technology to make a series of children's literature masterpieces into tactile picture books.

Tom Yeh is a professor of computer science at the University of Colorado at Boulder. He notes that traditional publishing methods are no longer sufficient for the needs of visually impaired children, and that the tactile picture book project he led is tailored for this group. solution.

“My main idea is to replace 2D with 3D, which is more suitable for children,” said Professor Tom Yeh. “Our team is using information and mathematics to provide a solution for parents, teachers and 3D printing technology to print a variety of picture books.”

The story of each page in the book consists of a three-dimensional image and a Braille text description at the end of the page. Currently, Professor Tom Yeh's team has published children's books including The Very Hungry Caterpilla, Noah's Ark, and some intellectual game books and map atlases.

“The process of designing these tactile picture books is an exciting and exciting experience for me,” said Caleb Hsu, a student at Boulder, who said that Noah’s Ark was his project. “Especially the teacher’s concern about the individual needs of each visually impaired child has deeply touched me. I need to give up some of my daily work, but it’s better than designing the beautiful and interesting works that attract people’s attention. Begin to learn to consider the needs of others. For those who use the hand to perceive the world, what kind of design can help them, and it is also educational."

Currently, Professor Tom Yeh's team has uploaded the open source digital files of these picture books to the "Tactile Picture Books" online library, allowing any user to use the project for free using 3D printing technology.
