Problems solved by technology

These people need special help to be able to cope with daily life. In recent years, targeted technological developments have also brought many changes to their daily life and work, but there are still many aspects that are not as convenient as those with normal vision.
[0003] With the rapid development of information technology today, information products developed for the blind only need to focus on the development of communication terminals that support Braille input to send short messages, and have achieved relatively good promotion and application value and technical effects. It is possible for people to enjoy the convenience brought by information technology, but this technology is also limited to enable blind people to input and send short messages, and it cannot reali

Abstract

The invention relates to a digital terminal supporting Braille input and a Braille input method, wherein the digital terminal comprises a key input unit including a Braille position input key group and an operation functional key group, a key identification unit, a Braille processing unit, an application layer unit, a character and speech synthesis unit, an audio frequency drive unit and an audio frequency generating unit, wherein the audio frequency driving unit is used for driving the audio generating unit to generate audio frequency. The digital terminal supporting Braille input and the Braille input method can realize barrier-free character communication between the blind and persons with vision disorder, thereby being beneficial to popularization and application.

Description

technical field [0001] The invention relates to Braille input technology, in particular to a digital terminal supporting Braille input and a Braille input method thereof. Background technique [0002] According to authoritative statistics, at present, there are more than 45 million blind people in the world. In China alone, the number of blind and visually impaired people is more than 5 million, and 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. In recent years, targeted technological developments have also brought many changes to their daily life and work, but there are still many aspects that are not as convenient as those with normal vision. [0003] With the rapid development of information technology today, information products developed for the blind only need to focus on the development of communication terminals that support Braille input to send short messages,...
