AI Technical Summary

Technical Problem

Existing Braille Chinese character input technologies have shortcomings in terms of encoding capacity, input efficiency, error tolerance, and feedback mechanisms. They are unable to simultaneously support rapid input of high-frequency Chinese characters, extended input of low-frequency Chinese characters, effective error handling, and multimodal collaborative feedback, thus affecting the input efficiency and operational stability of visually impaired users.

Method used

The method of eight-point Braille hierarchical coding is adopted, which divides the coding space into control code, single-cell high-frequency Chinese character code and prefix code set. Non-high-frequency Chinese characters are encoded using double-cell coding. Combined with candidate sorting and error correction mechanism, multimodal feedback is provided, and system parameters are dynamically adjusted to improve input efficiency and stability.

Benefits of technology

It combines single-grid direct output of high-frequency Chinese characters with double-grid input of non-high-frequency Chinese characters, reducing the probability of errors, improving input efficiency and operational stability, enhancing users' ability to instantly confirm input results, and adapting to different user habits.

Abstract

The application discloses a kind of based on eight-point braille hierarchical coding Chinese character input method and system, belong to braille information processing and barrier-free man-machine interaction field.The input method will the global coding space of first input grid be divided into control code set, single grid high frequency Chinese character code set and prefix code set, suffix code set only in extended waiting state in second input grid, realize high frequency Chinese character single grid input and non-high frequency Chinese character double grid extension input.Input system includes code table configuration module, input acquisition module, decoding processing module, candidate sorting and error correction module, result output module and adaptive updating module, for acquisition eight-point braille signal, carry out single grid direct translation or double grid decoding, and carry out error correction search when coding result is illegal coding, and candidate sorting parameter is updated based on user historical use record according to error correction candidate combination comprehensive score and confidence degree sorting.The application improves the Chinese character input efficiency and operation stability of visually impaired user.
