Portable Braille reader

Abstract

The invention belongs to the field of Braille readers and relates to a portable Braille reader which is convenient for the blind to use for reading e-books. An enclosure (1) is provided with a full-page-type Braille dot display screen (15), functional keys and a USB interface J2. A hardware control system is installed in the enclosure (1) and composed of an FPGA master control module (11), a USB communication module (10), a power management module (9), a high-voltage driving module (13) and a Braille dot matrix driving module (14). By operating the functional keys, selection is made as required, data information in a U-disk can be transferred to the FPGA master control module (11) through the USB communication module (10), corresponding software is executed, a corresponding function is completed, and thus the blind can read fast and conveniently through the Braille dot display screen (15). The portable Braille reader is small in size and convenient to carry; the portable Braille reader accords with the operation habit of the blind and thus is convenient for the blind to use for recognizing and reading; the reading cost can be reduced for the blind, the portable Braille reader is good for the blind to participate in the society equally, the living standard is raised, and the portable Braille reader has good 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 existing technology, for the blind people, the special group, the opportunities for reading and learning are very limited, and they are basically limited to direct reading of periodicals and books published in Braille. 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, for example, Microsoft and Pulse International Data Corporation jointly announced in 2000 that they planned to launch e-books for blind and visually impaired people, and the US government standardization agency also launched A book reader that converts electronic text to Braille; however, as far as the public Braill...

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)
