Method and device for gradually blanking character strokes

Abstract

The invention discloses a method for gradually blanking character strokes, comprising the following steps of: collecting a user stroke input handwriting and recording a two-dimensional coordinate array for each stroke; respectively storing each input new stroke into a cache region; carrying out gradual blanking treatment on history strokes in each cache region; and displaying the newly input strokes in the cache region and the history strokes after the gradual blanking treatment in real time in a writing area. With the method disclosed by the invention, the gradual blanking treatment on the character strokes are effectively provided for overlapped handwriting input at the same position or within a certain area. In a process of inputting by a user, the gradual blanking treatment is carried out on the strokes in the former characters in sequence with inputting a plurality of the characters, so that the user can clearly see the character which is input currently. Therefore, more characters can be input once and the input efficiency of handwriting identification technology is improved overall.

Description

technical field [0001] The invention relates to the technical field of handwriting input, in particular to a method and device for gradually changing and hiding character strokes. Background technique [0002] When a user uses an electronic device that supports handwriting input, the screen range of the electronic device is relatively limited due to technical and cost reasons during the handwriting input process. Therefore, most electronic devices that support handwriting input support overlapping handwriting technology. Redundant handwriting is a way of handwriting input. In traditional redundant handwriting input, after the user continuously inputs several characters, the strokes of each character will be completely mixed together, making it impossible to distinguish the currently input character, resulting in input errors and affecting the overall Accuracy and efficiency of handwriting recognition. [0003] The above-mentioned problem of inability to accurately and effic...

Redundant handwriting is a way of handwriting input. In traditional handwriting input, after the user continuously inputs several characters, the strokes of each character will be completely mixed together, making it impossible to distinguish the currently input character, resulting in input errors and affecting the overall Accuracy and efficiency of handwriting recognition

[0003] The above-mentioned problem of inability to accurately and efficiently distinguish input characters also exists in the line recognition overwriting technology. Input the entire line of characters on the terminal device, and achieve a higher writing effect by cross-writing left and right, but after writing multiple characters , the strokes will be mixed and overlapped, which will also make it impossible to continue normal input

[0004] In view of the above problems, the prior art proposes a solution, which can realize the function of fast input of character superimposition in the overlapping character and line recognition technology, but due to the problem of mixed strokes, it is impossible to continuously input multiple characters, even if using The method of superimposing writing on the left and right in turn may still have the problem of unrecognizable stroke superposition
