Unifying Braille Notation for Convenience and Public Facilities

Ministry of Culture, Sports and Tourism Revises 'Korean Braille Regulations'... Establishes Physical Standards for Braille

On the 10th, the Ministry of Culture, Sports and Tourism announced that it has established physical standards for braille to provide accurate information to visually impaired individuals. The "Korean Braille Regulations" were updated to include different usage standards depending on materials such as paper, stickers, PVC, and stainless steel. An official explained the background of the revision, stating, "There was an issue where braille signs installed in convenience and public facilities did not provide accurate information because the protrusion height of the dots was too low or the spacing between dots or characters was too wide."

To ensure uniformity in braille notation, the Ministry conducted research on "Standardization of Braille Utilization Specifications" in 2016 and established physical standards for braille after deliberation by the Braille Policy Advisory Committee. The height of the dots was set between 0.6 mm and 0.9 mm. The diameter and spacing between dots were set at 1.5 mm to 1.6 mm and 2.3 mm to 2.5 mm, respectively. The spacing between characters was set to be used as 0.6 mm to 0.9 mm for paper and stickers, 5.5 mm to 7.3 mm for PVC, and 5.5 mm to 7.6 mm for aluminum and stainless steel. The minimum line spacing was specified as 10.0 mm. The official added, "We will distribute the revised regulations to relevant organizations promptly and publish an explanatory guide on braille standards on the National Institute of the Korean Language website."
