In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The following detailed description of specific implementations of the present invention is provided in conjunction with specific embodiments:
the first embodiment is as follows:
fig. 1 shows a flowchart of an implementation of a method for playing back a written script according to an embodiment of the present invention, and for convenience of description, only the parts related to the embodiment of the present invention are shown, which is detailed as follows:
in step S101, a touch signal on the writing area is detected, and the touch time and coordinate information of the touch signal are acquired.
In the embodiment of the present invention, a touch signal of a user during writing is acquired through a touch panel, where the touch panel may be a mobile terminal device with a touch screen function, and the touch panel includes: mobile phones, tablet computers, learning machines, and the like. In order to accurately acquire the coordinate information of the touch signal, the area of the writing area can be enlarged by setting, and when a larger writing area is set, the coordinate information can be acquired more accurately.
In step S102, the coordinate information of the touch signal is sequentially stored according to the touch time of the touch signal.
In the embodiment of the invention, when the touch time of the touch signal is acquired, the coordinate information of the current touch signal is acquired at the same time, and the coordinate information of the touch signal is stored in sequence according to the sequence of the touch time of the touch signal, so that the complete writing process of a user is recorded.
Preferably, the time interval between the touch signals is matched with a preset time interval;
storing the coordinate information of the touch signal as corresponding writing handwriting according to the matched preset time interval, wherein the writing handwriting comprises: stroke script and character script.
Specifically, in the process of writing a character, each stroke in the character is relatively coherent, a certain time interval exists between the strokes, meanwhile, a certain time interval also exists between the characters, whether a stroke is finished or a character is finished can be judged according to the time interval between the strokes and the time interval between the characters, the time interval between the strokes and the time interval between the characters can be acquired according to a large amount of experimental data or the writing habit of a user within a certain time, the time interval between the strokes and the time interval between the characters can be acquired, the time interval between the strokes and the time interval between the characters can form a preset time interval, when the user writes, the time interval between touch signals can be matched with the preset time interval, and therefore the preset time interval can be matched, and correspondingly storing the coordinate information as the corresponding writing handwriting, for example, if the matched preset time interval is the time interval between strokes, correspondingly storing the coordinate information as the writing handwriting, and if the matched preset time interval is the time interval between characters, correspondingly storing the coordinate information as the writing handwriting.
And further, forming a corresponding thumbnail according to the handwriting.
Specifically, after the coordinate information of the touch signal is stored as the corresponding writing, the image of the writing can be acquired to form a thumbnail, so that a user can conveniently and visually find the previous writing content, and particularly, under the condition of continuously writing a plurality of characters, the previous writing content can be visually seen through the thumbnail corresponding to the writing.
In step S103, when a playback request is received, coordinate information of the touch signal is sequentially displayed on the writing area according to the touch time of the touch signal.
In the embodiment of the invention, after the user finishes writing, the previous writing needs to be played back, and at the moment, the user can obtain the previous complete writing handwriting by sending a playback request. When a playback request is received, displaying the coordinate information of the touch signals on the writing area in sequence according to the sequence of the touch time of the touch signals, so that the previous complete writing process of a user is displayed on the writing area.
Further, when a playback request is received, a playback mode is acquired, the playback mode including: decomposing and replaying according to handwriting and decomposing and replaying according to strokes;
and adjusting the corresponding display rate according to the playback mode.
In the embodiment of the present invention, when a user sends a playback request, different playback modes can be selected according to their own requirements, including: and decomposing and replaying according to handwriting and decomposing and replaying according to strokes. Specifically, the handwriting decomposition playback means that a character takes strokes as a unit, and the playback speed of each stroke is accelerated during playback, and the playback mode is more suitable for the condition that whether the writing stroke sequence is wrong needs to be checked through playback; the stroke-resolved playback means that the playback rate of each stroke is slowed down during playback, and the playback mode is more suitable for the writing mode which needs to be checked specifically to each stroke through the playback.
Further, a corresponding character template is displayed on the writing area.
In the embodiment of the invention, in order to further help a user to improve the writing level, the corresponding character template can be displayed on the writing area, so that the user can copy and write by referring to the corresponding character template during writing, and the improvement of the writing level is facilitated.
In the embodiment of the invention, when a user writes on the touch panel, the touch signals on the writing area are acquired, and the coordinate information of the touch signals is recorded in sequence according to the sequence of the touch time, so that when the user requests playback, the original previous writing handwriting is also recorded in sequence according to the touch time, the user can see the whole writing process, the problems in details such as the writing sequence and the like can be found, the user is helped to correct the writing habit, and the writing level is improved.
