Handwriting Input Recognition via Track Set Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices have a low recognition rate for input characters like punctuation marks in handwriting input mode, leading to a large range of candidate characters and reduced input efficiency due to difficulty in accurately distinguishing between punctuation and simple characters.
Innovation Solution
An input method and electronic device that detect a first track set corresponding to a predetermined identifier, allowing association of a second track set with related characters, thereby improving recognition and reducing candidate characters by using predetermined identifiers and position relations to narrow down possible inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If handwriting input mode is used, then ease of operation is improved, but recognition rate deteriorates
Solution Approach 1:
The system performs preliminary recognition on the first track set before final recognition of the second track set. By pre-identifying punctuation marks and special symbols in the first track set, the system narrows down the candidate characters for the second track set, thereby improving recognition rate while maintaining handwriting input convenience
Solution Approach 2:
The input method divides the handwriting input into two separate track sets: first track set for preliminary character input and second track set for refined character input. This segmentation allows the system to process recognition in stages, first identifying punctuation/symbols and then determining the final character, which resolves the contradiction between ease of operation and recognition accuracy
2Adaptability or versatility
If database search is performed for similar characters, then adaptability is improved, but productivity deteriorates
Solution Approach 1:
The system extracts and removes punctuation marks and special symbols from the general character database search process. By identifying these characters in the first track set and excluding them from the second track set candidate pool, the system reduces the database search scope from all similar characters to only relevant alphanumeric characters, thereby improving input efficiency while maintaining adaptability
Solution Approach 2:
The system performs preliminary filtering of the character database by using recognition results from the first track set to constrain the candidate pool for the second track set. This preliminary action reduces the number of characters that need to be searched and compared, improving productivity while maintaining the system's ability to handle diverse character inputs

AI summary
An input method and an electronic device are provided. The input method includes: detecting a presence of a first track set which corresponds to a first predetermined identifier, wherein the first track set comprises at least one track and is inputted into the electronic device; and if the first track set corresponds to the first predetermined identifier, associating a second track set with at least one second predetermined character that is related to the first predetermined identifier, wherein the second track set comprises at least one second track and is inputted into the electronic device after the first track set has been inputted. Recognition ability of the electronic device for the character is improved, and the input efficiency is increased.
