Description

Braille learning machine for converting plaintext into Braille

Technical Field

The utility model belongs to the technical field of the relevant technique of braille study and specifically relates to indicate a plaintext changes braille learning machine.

Background

Braille, also called braille and raised letters, is specially designed for blind people and is sensed by touch. It is created by French blind man Louis Blale in 1824, each Braille character is a rectangular blind symbol with six fixed positions, each point can be protruded or not protruded, forming 64 possibilities. The six points are divided into left and right columns, the upper row, the middle row and the lower row, the left column is called 1, 2 and 3 points from top to bottom, and the right column is called 4, 5 and 6 points from top to bottom. The current Chinese braille uses the Chinese pinyin to represent Chinese characters, and three blind symbols respectively represent initial consonants, vowels and tones to form a pronunciation.

There are many tools for visually impaired people to read, but few tools for teaching blind people to learn braille. The current braille learning activity is created through the braille environment, and the learning method is to learn 52 braille letters first and then learn pinyin, words and sentences. The method is characterized in that the blind feels the Braille information and experiences the Braille information by touching with fingertips, listening to the Braille, reading the Braille and the like in various Braille information, and basically needs to be taught by teachers, so that the self-learning possibility is very low. In the braille learning stage, the simple conversion from the auditory sense to the tactile sense or the simple conversion of the tactile sense as the first sense of understanding is very difficult, and if the existing braille learning machine can realize the function of converting the voice input into the corresponding braille output, the braille learning by the blind can become very simple, the learning efficiency can be greatly improved, and the function can not be realized by the existing braille learning machine at present.
