Recently, as the smart phone market grows explosively, there exists a large difference of utilization of the smart phone between an usual people and the visually impaired people. In this paper, We propose the character and numer ic input system based on the low cost of braille film and braille for the visually impaired people in order to reduce to information literacy gap for the visually impaired people. The proposed system is designed with the braille film and keyboard layout based on the braille character layout. Additionally, the telephone, the SMS, the abbreviated dial and location transfer function for the emergency situation are designed. The character which inputs using the braille keyboard can be automatically copied in the clip board and used in the other applications. Hence, the visually impaired people can easily use the smart phone for getting plentiful information on the device and network.
