Problems solved by technology

[0009] But obviously these existing input methods are very difficult to use for the blind;
[0010] Another method is to define 6 keys on the standard keyboard, corresponding to the six convex points of Braille, and use two hands to operate. The three fingers of the left and right hands correspond to the three points on the left and right of the Braille character. Correspondingly, relatively speaking, the blind do not need to spend too much time to learn, but it is still very inconvenient because several fingers are often required to press the keys at the same time during operation.

Embodiment Construction

[0061] In order to make the objectives, technical solutions and advantages of the present invention clearer, a Braille computer Braille input system, device and method of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0062] Aiming at the problems existing in the existing Braille input methods, the present invention proposes a Braille computer Braille input system, the basic principle of which is: according to the feature that the computer handwriting board 4 can read the trajectory of the writing pen, the blind people can use it on paper. The Braille template is installed on the computer handwriting board 4, so that when a blind person brailles on this board, he can input the coordinates of the Braille characters into the computer 6 through t...

Abstract

The system comprises: a handwriting board, a computer, a braille input guide board, a braille pen and a braille processing module. Said braille input guide board has a same size with the writing area of the handwriting board and is mounted on the surface of the handwriting board; said handwriting board is connected to said computer through an interface; said braille processing module is used for processing the braille input signals from the handwriting board when user uses the braille pen and braille input board to make input on the handwriting board.

Description

technical field [0001] The present invention relates to the field of computer input devices, in particular to a Braille computer Braille input system, device and method. Background technique [0002] There are two main types of Braille schemes commonly used in my country. One is the Braille scheme promulgated by the former Ministry of Education in 1953 and implemented nationwide, referred to as "Current Braille". This scheme has 21 initials, 34 finals, tone symbols and Punctuation. It takes Beijing pronunciation as the standard, Mandarin as the basis, word as the unit, and adopts the rules of word segmentation. Another Braille program is the Braille reform program approved by the State Language and Character Work Committee in 1988 for trial promotion, referred to as "Chinese Double Spelling Braille". The system includes: alphabet, punctuation, consensus differentiation method, abbreviation method, subsyllabic character method, etc., and also adopts the rules of word partici...
