2. Braille dot display V3
Tsinghua Braille Dot Display V3 can display the information on the computer synchronously in Braille, which is convenient for blind readers to touch and read. Tsinghua THDZ40 Braille pointer consists of 40 automatic Braille units, which can translate the text information on the computer into Braille and display it automatically through screen reading software. Blind readers can touch the ever-changing Braille on the Braille unit with their hands to get the information displayed on the computer screen. Braille dot display is very important for blind readers to learn. Because of the introduction of touch when using the computer, it can greatly deepen the learning effect of blind readers and deepen their memory of learning content. At the same time, the speed of touching and reading is faster than that of listening and reading, which is beneficial for blind readers to master what they have learned more efficiently. For the convenience of blind readers, every blind computer can be equipped with a Braille dot display.

The world's first reading machine that can be connected with Braille point display equipment can not only read by voice, but also display Braille, providing touch reading, making reading easier, especially suitable for libraries. Blind readers, also known as blind readers, can directly convert written words into speech, which is suitable for blind people to "listen" to read. The system consists of a desktop scanner and corresponding Chinese character recognition software. The former is connected with a computer, and the latter recognizes the scanned Chinese characters, stores the recognition results in an editor, and then reads them out. The operation of this system is very simple, and there are voice prompts at every step. Blind readers can master the usage with a little learning and operate independently without the help of others.
4. Braille printer
The engraving machine can engrave the files on the computer into raised Braille files on paper. The DOG series Braille Engraving Machine, launched by the Language and Character Information Processing Research Center of the Department of Automation of Tsinghua University in cooperation with Japanese companies, is an internationally advanced product with high cost performance, which is used in many libraries and blind schools in China. DOG series braille printers are the lowest noise braille printers in the world, which are not as noisy as ordinary braille printers and are very suitable for libraries. In addition to the dog-based Braille engraving machine, the dog multi-Braille engraving machine can also print the contrast between Braille and Braille at the same time, which is convenient for the blind to touch and read. DOG-PRO32 Braille printer can also print double-sided Braille at the same time, which greatly improves the printing efficiency.

For readers with low vision, CCTV screen vision AIDS (also known as vision amplifiers and vision AIDS) are composed of image scanners and high-definition electronic display screens, which can enlarge images and characters on paper, books and even three-dimensional objects, and can be displayed in various contrast modes and magnifications such as color, black and white, which is convenient for students with low vision and different eye sensitivities. There are many products for CCTV screen auxiliary equipment to choose from, such as portable and desktop. It makes up for the defect that low-vision readers' perception of things is affected by blurred vision, and makes it more convenient for low-vision readers to consult books and newspapers.
Auxiliary parameters of CCTV screen vision: performance parameters: display screen size 17/ 19 inches. The screen can be adjusted at will. The mobile response time is 8ms, and the zoom factor of quick response is 2.7 ~ 58 times. 6. Blind screen reading software.
Screen reading software for the blind adopts Tsinghua Double Star screen reading software. According to the operating habits of the blind, the software makes full use of the hearing of the blind. Under the existing Windows system environment, various application softwares are specially developed for specific use requirements. It also adopts voice prompt, which is suitable for blind people to operate independently, convenient and flexible. Software integrated voice navigation relies on auditory operation, taking into account the compatibility of software and the particularity of blind operation. Blind people can make full use of all kinds of general software (such as Word, IE browser, etc. ) and give full play to the specialty of blind software.
7. Chinese-blind translation conversion typesetting software
The system adapts to the mainstream computer operating system, and can directly translate Chinese articles into Braille and electronic Chinese into Braille. It can output pure Braille text or blind Chinese contrast text, and provide synchronous editing and modification function of blind Chinese contrast text. With the help of Braille printer (refer to the introduction of Braille printer in item 4 above), it can print Braille for blind readers on paper. The system can automatically handle the typesetting of Braille, and the system can choose typing points, Chinese Pinyin and other input methods, which provides convenience for the discerning and blind. The system provides the output interface of Braille printer.
