Luciole (French for “firefly”) is a new typeface developed explicitly for visually impaired people. The result of a two-year collaboration between the Centre Technique Régional pour la Déficience Visuelle (the Regional Technical Center for Visual Impairment) and the type-design studio typographies.fr, this project received a grant from the Swiss Ceres Foundation and support from the DIPHE laboratory at the Université Lumière Lyon 2.
