PCT is a brand that creates tactile content and hardware for the visually impaired. For visually impaired people, manipulating blocks and hearing sounds provides a fun and practical learning experience. Since this positive experience can increase learning motivation and encourage continuous learning, we designed it with the theme of 'a toy familiar to everyone' rather than a learning tool. It is designed to be easy to get used to by placing a block in the hole of the Braille learning device and operating it to produce a sound corresponding to the corresponding Braille.
