Detailed Description
The following describes the embodiments of the present invention with reference to the drawings and examples.
An embodiment of the present invention provides a method for correcting an error of a touch screen, as shown in fig. 1, including the following steps:
step s101, receiving an input stroke action;
and step s102, judging that the stroke action is an erasing action according to the stroke action or the stroke model, correcting according to the erasing action, and displaying the character corrected by the erasing action on the touch screen.
In this step, if it is determined that the stroke motion is not the erasing motion according to the stroke motion or the stroke model, it is determined that the stroke motion is the writing motion. Wherein, judging the stroke action to be the erasing action according to the stroke action or the stroke model comprises the following steps:
and when the stroke model accords with the first threshold condition, judging that the stroke action is an erasing action according to the stroke model.
Meanwhile, when the stroke model accords with a second threshold value condition, the stroke action is judged to be a writing action according to the stroke model.
The first threshold condition and the second threshold condition can be flexibly set as follows: the first threshold condition is that the range of the touch screen covered by the hand or the handwriting device is set to be thick, and the second threshold condition is that the range of the touch screen covered by the hand or the handwriting device is set to be thin and the range is one scale of thick and thin fingers; similarly, when the first threshold condition is that the range of the touch screen covered by the hand or the handwriting device is set to be thin, the second threshold condition is that the range of the touch screen covered by the hand or the handwriting device is set to be thick.
On the other hand, the determination that the stroke action is the stroke erasing action according to the stroke action or the stroke model in the embodiment includes the following steps: when the stroke action is to move along the original stroke and/or against the original stroke within a certain range of the original stroke, or to move frequently left and right of the original stroke, the stroke action is judged to be an erasing action.
In the foregoing description of this embodiment, displaying the characters after the erasing action is corrected on the touch screen specifically includes: and displaying a plurality of matched characters corrected by the erasing action on the touch screen, acquiring selection information, and displaying characters corresponding to the selection information.
The second embodiment of the present invention provides a method for correcting errors of a touch screen, which applies the second embodiment to a specific scenario, as shown in fig. 2, and includes the following steps:
step s201, determining whether the user performs stroke erasure correction according to the stroke model in the stroke input action received by the touch screen.
In this step, the handwriting device may be a handwriting device as shown in fig. 3, and is composed of a writing end 10, a handheld end 20, and an error correction end 30; wherein the stylus 10 and the stylus 30 may define the thickness dimension of the port differently in different application scenarios. Meanwhile, the handwriting device shown in fig. 2 can be directly replaced by fingers, and the distinguishing processing is carried out according to the range of the fingers covering the touch screen, so that the handwriting device shown in fig. 3 represents error correction when the thumb covers the touch screen in a large area, and represents writing when the thumb covers the touch screen in a small area, namely new handwriting input. In this step, since the determination of the input stroke model and stroke action is performed simultaneously, that is, when the user performs writing or erasing stroke input, the system also obtains the input stroke model simultaneously.
And step s202, correcting according to the stroke input action of the user, and displaying a plurality of matched characters after the stroke erasing action is corrected on the touch screen.
For example: the \ "Shen \" is corrected to \ "day \", the user's input action is to erase the original strokes by covering the vertical area of the strokes of the \ "Shen \" with the error correction end 30 of the handwriting device, and then the system displays the characters \ "day \" and \ "on the touch screen, which are matched with or similar to the stroke erasure action. Some similar characters can be further displayed when the system function allows; for example: "Tian", "Yi", "Jia", etc.
And step s203, acquiring the selection information and displaying characters corresponding to the selection information.
And if the user selects the characters which are consistent with the self error correction intention, such as the date, the touch screen receives the selection information of the date and displays the date on the touch screen.
In this embodiment, the erased stroke may be a whole stroke, or a part of the stroke may be erased, for example: the 'Shen' is corrected to be 'A', the user only needs to locally erase on the upper part of the vertical stroke, the function of the error correction end 30 of the handwriting device is equivalent to that of an eraser, similarly, the system can call characters matched with the user intention or similar characters in the character library to be displayed on the touch screen, and the user can select and confirm the characters.
The third embodiment of the invention provides a method for correcting errors of a touch screen, which applies the third embodiment to a specific scene, and corrects the errors according to the input stroke actions, wherein the processing process comprises the following steps:
the user directly performs handwriting input by using the handwriting terminal 10 of the handwriting device shown in fig. 3, and determines that the stroke motion is an erasing motion when the obtained stroke motion is frequently stroked left and right in the original writing stroke or stroked along the original stroke and/or the inverse original stroke within a certain range of the original stroke. For example: when the user needs to correct the 'shen' into 'first', the writing end 10 is directly used for carrying out multiple strokes left and right on the part needing to be erased on the upper part of the vertical stroke of the 'shen' character or carrying out strokes along the original stroke and/or the inverse original stroke in a certain area of the erasing part, the system judges that the erasing action is carried out, and the upper part of the stroke is erased.
In the description of the above embodiment, it is determined whether the stroke action is a stroke erasing action according to a stroke action or a stroke model; wherein the determination of the stroke type is actually that the finger or handwriting device port entity covers the range of the touch screen. Meanwhile, the technical scheme of the invention also comprises the step of clicking a certain button by using a handwriting device to delete the whole font, namely writing a wrong character, and also can directly erase the whole character.
