Read-write learning instrument for visually impaired students

Abstract

The invention discloses a read-write learning instrument for visually impaired students. The instrument comprises a base, a book placing position, a control module, a camera, a touch dot matrix and a mode switching switch, the camera, the touch dot matrix and the mode switching switch are connected with the control module, the book placing position and the touch dot matrix are distributed on the top face of the base, and a groove is formed in the book placing position and used for placing materials to be read; a support is arranged on the base, and the camera is arranged above the book placing position through the support so as to collect images of materials to be read and send the images to the control module; the control module recognizes text information in the image, converts the text information into corresponding braille codes and then controls the touch dot matrix, and the touch dot matrix comprises a plurality of heating tube dot matrixes distributed in a dot matrix mode. According to the invention, the visually impaired students can conveniently recognize braille alphabets by sensing the temperature difference of the braille alphabet touch dot matrix through fingers so as to read character information, and the braille alphabets can be input through the touch dot matrix so as to realize the reading and writing of the braille alphabets.

Description

technical field [0001] The invention relates to a reading and writing learning instrument for visually impaired students. Background technique [0002] According to a report released by the World Health Organization in 2018, about 285 million people in the world are visually impaired, of which 39 million are blind. For them, it is extremely difficult to read independently except for Braille materials; the visually impaired Students mainly rely on hearing and touch to obtain information. There are two main types of reading resources: one is braille publications that are read by fingers, and the other is audiobooks that are read by fingers; products for visually impaired students are mostly voice-controlled or the method of converting text information into sound information; audiobooks have relatively large limitations, such as the sound they make will affect others, and the sound will reveal privacy, etc.; the types of Braille publications are limited, the information lags be...

[0002] According to a report released by the World Health Organization in 2018, about 285 million people in the world are visually impaired, of which 39 million are blind. For them, it is extremely difficult to read independently except for Braille materials; the visually impaired Students mainly rely on hearing and touch to obtain information. There are two types of reading resources: one is braille publications that are read by fingers, and the other is audiobooks that are read by fingers; products for visually impaired students are mostly voice-controlled or the method of converting text information into sound information; audiobooks have relatively large limitations, such as the sound they make will affect others, and the sound will reveal privacy, etc.; the types of Braille publications are limited, the information lags behind, and it is impossible to obtain the latest news Newspapers and other real-time information, and Braille publications cannot be reused. When you need to read other materials, you need to buy new Braille publications again; touch products have not been fully developed and utilized, and there are relevant Chinese character conversion Braille programming. Disciplinary research, but the sales price of market products is extremely expensive

[0003] In the process of learning, listening, speaking, reading and writing all complement each other. For students, it is far from enough to only read information to acquire knowledge without thinking and write down their own experience. The learning of words cannot be replaced by sound. Therefore, how to enable visually impaired students to read and write efficiently and conveniently has become a big problem
