A portable braille reader

Abstract

A portable braille reader belongs to the field of braille readers and solves the problem that blind people can read electronic books conveniently; 2 , the casing (1) is equipped with a hardware control system, which consists of an FPGA main control module (11), a USB communication module (10), a power management module (9), a high voltage drive module (13) and a Braille dot matrix drive module (14) Composition; by operating the function buttons and selecting the needs as required, the data information in the USB flash drive can be transmitted to the FPGA main control module (11) through the USB communication module (10), and the corresponding software is executed to complete the corresponding functions. The display screen (15) can be read quickly and conveniently; it is small in size and portable, conforms to the operating habits of the blind, is convenient for the blind to use, identify and read, can reduce the cost of reading for the blind, is beneficial to the equal participation of the blind in society, and improves their living standards. public welfare.

Description

technical field [0001] The invention belongs to the field of braille reading devices, and relates to a portable braille reader. Background technique [0002] In the prior art, for the special group of the blind, the opportunities for reading and learning are very limited, and are basically limited to direct reading of periodicals and books published in Braille, and the variety and quantity of Braille publications are very strange.

Problems solved by technology

[0002] In the prior art, for the special group of the blind, the opportunities for reading and learning are very limited, and are basically limited to direct reading of periodicals and books published in Braille, and the variety and quantity of Braille publications are very strange. It is far from being able to meet the increasing reading needs of blind readers

[0003] With the development of electronic publishing technology and attention to the improvement of the quality of life of disadvantaged groups, such as Microsoft and Pulse International Data Corporation jointly announced in 2000 that they planned to launch e-books for the blind and visually impaired, and the US government standardization agency also launched A book reader that converts electronic text to Braille; but as far as the disclosed Braille electronic reading devices are concerned, most of them are Braille reading devices based on text and graphic recognition and / or voice broadcasting. A Braille electronic reader for reading e-books (referring to e-books in plain text Chinese character file format) stored in a USB flash drive or a removable hard disk on a Braille touch-sensitive screen (hereinafter referred to as a Braille dot display screen)
