Braille inputting device and method based on micro button switch

Abstract

The invention provides a braille inputting device and a braille inputting method based on a micro button switch. A user presses someone micro button on the device, the micro button switch is closed to form a switch loop on one blind character point, and a processor on the device obtains the position information of the blind character point and converts the position information of the blind character point to a blind character code. According to the braille inputting device and the braille inputting method, the micro processor is used as a control component, and micro buttons form a braille array, so that the computer braille inputting function of the braille is achieved by a coding circuit and a braille processing program. The invention has the advantages of strong universality, low cost, convenience in use, and the like, accords with the use habit of a blind person in braille writing at ordinary times, and has a wide application prospect.

Description

technical field [0001] The invention relates to the input field of electronic information equipment, in particular to a braille input device and method based on micro-button switches. Background technique [0002] The Braille coding scheme currently adopted in my country is mainly "Chinese double-spelling Braille", which can represent the three elements of Chinese sound, rhyme, and tone in two-sided braille characters. Method, subsyllable character method, etc., and also adopts the word segmentation and continuous writing rules. [0003] The Braille coding scheme takes "blind characters" as the basic structure, and a braille character consists of six dots Composition, referred to as a "square". The corresponding code can be expressed by permuting and combining the six points with or without bumps. [0004] Braille writing and reading are quite special. Braille writing is commonly known as Braille. When Braille is used, special paper is first pressed between the upper and ...

AI Technical Summary

Problems solved by technology

[0012] This keyboard input method corresponds to blind characters. Relatively speaking, blind people do not need to spend too much time learning, but it is still very inconvenient because several fingers are often required to press keys at the same time during operation, and it will take a considerable amount of time to fully master it. , the input speed cannot be too fast
