The Lego Foundation, which is funded by the Lego Group, the Danish toy company that makes the blocks, announced a new project that will repurpose the usual knobs atop the bricks as Braille dots. And because the blocks will also be stamped with the corresponding written letter, number or punctuation symbol, they can be played with by blind and sighted children alike. The project, called Lego Braille Bricks, is in a pilot phase and is expected to be released in partnership with schools and associations for the blind in 2020.
Braille, once widely taught in schools for the blind, has fallen by the wayside since the 1970s, when the law began requiring public schools to offer equal education to children with disabilities. Blind students were able to join their sighted peers in the classroom, but traditional schools, biased toward sight and facing a lack of specialized teachers, often pushed children with any sight at all to rely on magnified print. And an explosion of accessible technologies, including audiobooks, apps and screen readers, has strengthened reliance on audio, which advocates say cannot effectively teach critical skills like spelling and grammar, let alone complicated math.
