Abstract
Vietnam has about 2 million visual impairments people. In which only 8% go to school, 15% are trained in vocational centers and 20% have job opportunities. The blinds have many difficulties in living as well as learning and socializing. For the blind, learning Braille is the best way to minimize difficulties in all aspects of life. Each Braille is made up of 6 points; these points form a rectangular frame of two columns and three rows. The combination of six floatingsink points creates encoding for all characters. The scientific and technological solution that we have proposed with the goal of supporting Braille children to learn Braille in IoT applications. The product system includes many Braille coding devices for the blind; each module is used by a blind person. Each device is connected to the system’s server which is designed on the internet.
