Braille reading and writing device based on cold and heat signal

Abstract

The invention discloses a braille reading and writing device based on a cold and heat signal. The device comprises a system controller, a display screen, a writing screen, a control screen, a cold and heat pen, a data collector, a data storage and a power interface, wherein a cold and heat display part is embedded in the display screen; a temperature measuring part is embedded in the writing screen; a control screen temperature measuring part and a control screen cold and heat display part are embedded in the control screen; the cold and heat display part, the control screen cold and heat display part, the data collector, the data storage and the power interface are respectively connected with the system controller; and the temperature measuring part and the control screen temperature measuring part are connected with the data collector. The cold and heat signal is introduced into the braille reading and writing field for the first time to substitute a convex and concave characteristic, so that the large-area plane touch type braille reading and writing device without a movement component is realized. The device is novel and unique in principle, high in reliability, low in cost and large in display area and writing area, is easy to popularize and does not have the movement component.

Description

technical field [0001] The invention belongs to the field of information technology, in particular to a braille reading and writing device based on cold and hot signals. Background technique [0002] Braille, also known as Braille and raised characters, its smallest unit is "square", which is composed of six dots arranged in a certain irregular pattern. It is specially designed for the visually impaired and relies on tactile perception. It is also a visually impaired The primary means of written communication for people. The current international Braille "Braille" was created in 1824 by French blind Louis Blaille. Referring to the Blair Braille system in 1952, on the basis of the old Braille characters such as "Xinmu Keming Braille", after adjustment and innovation, China proposed "Mandarin" based on Putonghua, with Beijing phonetics as the standard, using the method of participle ligatures to spell Putonghua New Braille Program", which was promulgated and implemented nati...

AI Technical Summary

Problems solved by technology

However, at this stage, there is no in-depth research on smart phones for the visually impaired. Only simple modifications on ordinary mobile phones, such as replacing the buttons with buttons with Braille, or improving the voice function of the mobile phone, cannot really meet the needs of the visually impaired. mobile phone needs of the disabled

[0005] To sum up, the above-mentioned reader devices using braille embossed characters all have moving parts, which not only restricts the display area of ​​braille on the reader due to the complexity of the process, but also puts forward extremely high requirements on the reliability of the moving parts; However, readers and mobile phone systems that convert text information into language are complex in structure and expensive

So far, there is no large-area flat-touch Braille reading and writing device without moving parts
