An audiovisual and tactile matching method for Braille information barrier-free

Abstract

The invention discloses an audiovisual and tactile perception matching method for barrier-free Braille information. Traverse the initial text and the initial point sequence, read 37 bytes from the initial text each time as a text file, and read 126 bytes from the initial point sequence as a point sequence file; then according to the point sequence file Whether the 20th party and the 21st party are empty parties is judged and processed differently, and the point sequence file and the text file are intercepted and the point sequence is processed, and stored to form the final text file and the final point sequence file. The present invention can realize the synchronous presentation of visual, auditory and tactile multi-sensory information matching and presentation of text, sound and Braille dots, and can realize the correspondence between the contents of text files and point sequence files, so that the Braille learning machine can output visual stimulation and auditory stimulation of the same content. Stimulation and tactile stimulation, to solve the current Braille learning method based on paper books can only provide tactile stimulation of Braille dots, and there are problems such as non-portable, difficult to use, and outdated content.

Description

technical field [0001] The invention relates to a method for processing text information and point-order information in the barrier-free Braille information, in particular to an audio-visual touch perception matching method for the barrier-free Braille information, which can realize the visual, auditory and tactile effects of text, sound and Braille points. Simultaneous presentation of multi-sensing information enables the content of text files and point-order files to correspond to each other, so that the Braille learning machine can output visual, auditory and tactile stimuli of the same content, helping visually impaired people learn Braille correctly, efficiently and without obstacles. It belongs to the field of information accessibility technology. Background technique [0002] According to the World Health Organization, there are approximately 285 million visually impaired people in the world, of which 39 million are completely blind and 246 million are visually impair...

Problems solved by technology

In order to improve the learning efficiency of Braille, the present invention proposes a barrier-free audio-visual and tactile matching method for Braille information, which can realize the synchronous presentation of visual, auditory and tactile multi-sensory information of text, sound and Braille points, and can realize text files and The content of the dot sequence file corresponds to each other, so that the braille learning machine outputs the same content of visual stimulation, auditory stimulation and tactile stimulation, helping the visually impaired to learn braille correctly, efficiently and without barriers, and solves the problem of the current braille learning method based on paper books. It can provide tactile stimulation of Braille dots, but there are problems such as not portable, difficult to use, and outdated content
