On June 21, 2019, the Act on Promotion of Reading Environment for the Visually Impaired (Reading Barrier-Free Law) was passed and enacted at a plenary session of the House of Representatives and promulgated and enforced one week later on June 28. Through this project, Morpho AIS will work to achieve compliance of the Reading Barrier-Free Law, which “promotes the comprehensive and systematic development of reading environments for the visually impaired and others and contributes to the realization of a society where all citizens, regardless of disability, can equally enjoy the benefits of the written and printed word through reading” (*1).


Upon preparing the proposal for the Project, Morpho AIS sought the cooperation of Toppan Inc., which has experience in constructing OCR learning data sets, and commissioned the Project. Partnering with Toppan Inc., Morpho AIS will work on the commercialization of AI-OCR based on the knowledge acquired through this project.
