Problems solved by technology

Although this fast input method is accurate and fast, because the logos allowed to be used are generally simple strokes or special symbols, when the user defines too many logos or does not use the custom logo for a long time, it is easy for the user to Forget or confuse what the logo represen

example 1

[0066] see figure 2 , in this example, the judgment of the enclosing line can be completed in the following ways:

[0067] Step 201, acquiring a specific trace in the handwriting information; the specific trace is the first trace or the last trace;

[0068] Step 202, obtaining the maximum value and minimum value of the X coordinate and the maximum value and minimum value of the Y coordinate of the specific trajectory;

[0069] Step 203, obtaining the maximum value and minimum value of the X coordinate and the maximum value and minimum value of the Y coordinate of other stroke trajectories;

[0070] Step 204, compare the coordinate extreme values ​​of the above-mentioned specific stroke trajectory and other stroke traces; if the X coordinate extreme values ​​of the other stroke traces are all located between the X coordinate maximum value and minimum value of the specific stroke trajectory, If the extreme values ​​of the Y coordinates of the other stroke trajectories are all...

example 2

[0075] In this example, the judgment of the enclosing line can be completed in the following ways:

[0076] Obtain the first trace in the handwriting information;

[0077] Obtain the maximum value and minimum value of the X coordinate and the maximum value and minimum value of the Y coordinate of the first trajectory;

[0078] Obtain the maximum and minimum values ​​of the X coordinate and the maximum and minimum value of the Y coordinate of other stroke trajectories;

[0079] Compare the coordinate extremums of the above-mentioned first stroke trajectory and other stroke trajectory;

[0080] If the extreme values ​​of the X coordinates of the other stroke trajectories are all located between the maximum and minimum values ​​of the X coordinates of the first stroke trajectory, the extreme values ​​of the Y coordinates of the other stroke trajectories are all located in the first stroke trajectory Between the maximum value and the minimum value of the Y coordinate, then deter...

example 3

[0084] In this example, the judgment of the surrounding line can be completed in the following way: obtain the curve area of ​​the first stroke or the last stroke (if it is not closed, it can be virtual closed), and then count whether the coordinate points of other stroke traces fall in the above area Otherwise, if not, determine that the first or last trace is an enclosing line.

[0085] A specific embodiment is given below to further illustrate the present invention.

[0086] Define "Hanwang Technology Co., Ltd." as the identification character "Hanwang" in advance, so that when the user needs to input such a long sentence frequently in the text editing state, he only needs to write "Hanwang" on the handwriting input device and draw a Surrounding line, encases "Hanwang" (hereinafter referred to as the character with picture) (referring to attached Figure 4A ); when the system detects the encircling line, it will query the character recognition result "Hanwang" in the mappi...

Abstract

The invention provides a method of fast handwriting input, which comprises the steps: receiving handwriting information of a user; judging whether the handwriting information comprises predetermined trigger marks or not; if yes, identifying the handwriting information corresponding to the trigger marks; according to an identifying result, acquiring bulk information corresponding to the identifying result from a preset mapping table; using the mapping table to store all identification characters and bulk information corresponding to the identification characters; and outputting the bulk information. The invention distinguishes the identification characters from common characters by means of the trigger marks, so the user can freely set marks which are familiar to the user or are convenient for memorization without avoiding the common characters(for instance, a key word can represent a long sentence or a related command, and the like), therefore, the invention can greatly relieve the memory burden of the user, enlarges applicable occasions of mark transformation and further improves the efficiency of the handwriting input of the user.

Description

technical field [0001] The invention relates to the technical field of computer information input processing, in particular to a method and system for fast handwriting input on electronic equipment. Background technique [0002] In recent years, as the use of handwriting electronic devices has become more and more popular, such as PDA (Personal Digital Assistant), mobile phone, HPC (Handheld Computer) etc., the handwriting input method that arises with it has also become more and more important. Although there are many types of input methods in these electronic devices on the market, as people need to input and process more information, the requirements for handwriting input methods are also getting higher and higher. [0003] The handwriting input method in various electronic equipments on the market generally requires the user to write each character in sequence on the handwriting input device (such as a touch screen) of the equipment before the corresponding single charac...
