Abstract

The invention relates to a communication terminal supporting Braille input, and a relative Braille input method, wherein the communication terminal comprises a key input unit with key group arranged in matrix structure, a key recognizer for recognizing if the key input unit is operated and outputting key operation information, a Braille point combination recognizer for receiving key operation information, and combination recognizing the key operation information according to the relation between the keys and the Braille points and the standard Braille point structure, to output Braille character point information, a Braille display driver for receiving key operation information or Braille character point information to drive the Braille point display, a display unit driven by the Braille display driver to display Braille points, and a communicator for communicating with external devices. Via the invention, blind can input text of message without voice prompt.

Description

technical field [0001] The invention relates to the technical field of communication, more specifically, to a communication terminal supporting Braille input and a method for sending a Braille short message on the communication terminal. Background technique [0002] According to the World Health Organization, there are between 40 and 45 million blind people in the world. In China alone, the number of blind and visually disabled people is about 5 million, accounting for 0.4% of the total population. It is one of the countries with serious blindness and visual impairment in the world. These people need special help to be able to cope with daily life. Technological developments in recent years have brought many improvements to their lives, but there are still many aspects that are not as convenient as sighted people. [0003] Today, with the rapid development of communication, portable phones or various communication terminals can meet people's communication needs anytime and...
