Problems solved by technology

[0006] First, at the input trajectory level, it is impossible to intervene in the written strokes, and it is impossible to optimize the input trajectory or the combination of strokes to obtain more accurate candidate characters
[0007] Second, at the recognition level, there is no effective solution for the situations that are unfavorable for the input method system to recognize characters, such as "continuous strokes", "wrong strokes", and "wrong stroke order" that will occur when writing multiple Chinese characters in a continuous writing manner in an overlapping manner. way of correcting mistakes
[0008] Third, the simple intervention method of clearing wrong words is relatively simple, and if the number of written characters is long and there are many mistakes that need to be corrected, the amount of writing by the user will increase significantly, and the total time spent on writing by the user will increase significantly

Abstract

A Chinese character input system and method for continuous writing of Chinese characters and supporting interaction, relating to a Chinese character input system and method, in order to solve the problems of limited input function, low interactivity and low efficiency in the prior art. The system includes: an input module for receiving stroke trajectories input by users; an input module for collecting stroke trajectories input by users or collecting stroke trajectories corresponding to replacement strokes sent by the interactive optimization module, and collecting stroke trajectories according to the collection density The acquisition module of the above point; recognize the strokes and stroke order and score the candidate words and candidate word strings formed, and record the highest candidate word and candidate word string identification module of the scoring information; used to display the highest scoring information Candidate words, A display module for strings composed of consecutive characters; an interactive optimization module for monitoring the user's confirmation information and feedback actions on alternate incorrect candidate characters and incorrect strokes. The invention is suitable for error correction and input of Chinese characters.

Description

technical field [0001] The invention relates to a Chinese character input system and method. Background technique [0002] Information input When a user writes multiple Chinese characters continuously in overlapping or continuous writing, it is different from the user writing a single Chinese character. When writing, there will be "continuous strokes", "wrong strokes", "wrong stroke order", etc., which are not conducive to the input method. The case where the system recognizes the character. [0003] "Continuous strokes" usually refers to the connection between the last coordinate of the previous stroke and the first coordinate of the next stroke. Here, it is defined as when the user writes two or more independent strokes and writes them in a connected stroke. Case. "Wrong stroke" means that what should be written as one stroke is written as another stroke. "Wrong order of strokes" refers to writing Chinese characters not according to the uniform rules of stroke order of ...
