3D printing makes itself useful for blind children
" Hands of search " is a wonderful project initiated by Yahoo! Japan which demonstrates once again that 3D printing can have healing and educational virtues. At a school for blind children, engineers built a machine that combines voice recognition research with a 3D printer . The idea behind this is to allow children to feel, to touch the outlines of items they can not see. Touch is a primary meaning for the visually impaired. The principle is quite simple, the child presses a button and states something he would like to touch (dragons, giraffe, dinosaur, etc.). The machine searches among its bookseller for available 3D files . If she finds the object, the child just has to press another button to start printing the 3D model . For now the database of "Hands of search" includes 110 3D models but is destined to grow thanks to the contribution of individuals and companies.
