Please refer to FIG. 1. FIG. 1 is a schematic flowchart diagram of a method for page turning of a terminal according to an embodiment of the present invention. As shown in FIG. 1, the terminal page turning method may include the following steps:

S101. The tablet acquires a writing stroke input through the tablet.

In the embodiment of the present invention, when the user needs to use the tablet, the user can pad a piece of paper on the writing board, and then write on the paper with a stylus matched with the tablet, and the tablet can sense the movement of the stylus. The track is used to obtain a written handwriting input by the user, and the written handwriting is sent to the terminal with which the communication connection is established. The manner in which the tablet and the terminal establish a connection may be to establish a Bluetooth connection, a WIFI connection, a data line connection, and the like.

The terminal can download the supporting APP (Application, application) of the tablet, and after the terminal establishes a communication connection with the tablet, open the APP, and then can receive the writing handwriting sent by the tablet, and display the received writing handwriting, optionally, The terminal can also store the received writing handwriting, which is convenient for the user to view later. It should be noted that the content displayed on the terminal is the same as the content on the paper on the tablet.

Specifically, the writing handwriting includes a first writing handwriting and a second writing handwriting, and the writing tablet detects the writing handwriting input by the user. If no new writing handwriting is detected within the time interval T0, the written handwriting is determined as the first writing. Handwriting, and acquiring the first writing area S1 corresponding to the first writing handwriting. The specific determination manner of S1 may be: obtaining the leftmost horizontal coordinate value X0, the rightmost horizontal coordinate value X1, the lowermost vertical coordinate value Y0, and the uppermost vertical coordinate value Y1 of the first written handwriting; A rectangular area in which Y1), (X0, Y1), (X1, Y0), and (X1, Y1) are vertices is the writing area S1. After the time interval T0, if the written handwriting input by the user is detected again, and no new writing handwriting is detected within the next time interval T0, the written handwriting detected again is determined as the second writing handwriting, and the first writing hand is obtained. 2. Writing a second writing area S2 corresponding to the handwriting.

It should be noted that the time interval T0 may be 3 seconds, 5 seconds, etc., which may be set by the R&D personnel at the factory, or may be set by the user, which is not limited by the embodiment of the present invention.

S102. The tablet determines whether the preset page turning condition is met according to the writing handwriting. If yes, step S103 is performed; if not, the current flow is ended.

Specifically, the tablet detects whether the writing strokes of the user overlap, and if the area of the overlapping portion is greater than the preset area threshold, determining that the writing stroke meets the page turning condition, specifically comprising: the tablet detecting the first writing area S1 and the second writing area Whether the area of the overlapping area of S2 is greater than a preset area threshold, and if so, the tablet determines that the writing handwriting satisfies the page turning condition, and step S103 is performed.

The preset area threshold may be 10 square centimeters, 20 square centimeters, etc., and may be set by a developer or may be modified by a user, which is not limited by the embodiment of the present invention.

In some feasible implementation manners, if the area of the overlapping area of the first writing area S1 and the second writing area S2 is less than or equal to the preset area threshold, the tablet may combine S1 and S2 to process the combined writing area. As a new first writing area S1, and continue to acquire a new second writing area S2, and judge whether the preset page turning is satisfied according to the area of the overlapping area of the new first writing area S1 and the new second writing area S2. condition.

Optionally, the tablet can also detect the number of intersection points of the user's writing handwriting. If the number of intersecting points of the writing handwriting is greater than the preset number threshold, it is determined that the writing handwriting meets the page turning condition, and specifically includes: the tablet detecting Whether the number of intersections of the first handwriting and the second writing handwriting is greater than a preset number threshold, and if so, the tablet determines that the writing handwriting satisfies the page turning condition, and step S103 is performed.

The preset number of thresholds may be 10, 20, or the like, which may be set by the researcher or may be modified by the user, which is not limited by the embodiment of the present invention.

In some possible implementations, if the number of intersections of the first writing stroke and the second writing handwriting is less than or equal to a preset number threshold, the tablet may combine the first writing handwriting and the second writing handwriting.

S103. The tablet sends a page turning instruction to the terminal.

In the embodiment of the present invention, after the tablet determines that the written stroke of the user meets the page turning condition, the page turning instruction is sent to the terminal, where the page turning instruction is used to instruct the terminal to page the display content, and the display content includes the Write the writing content corresponding to the handwriting.

Correspondingly, after receiving the page turning instruction sent by the tablet, the terminal stores the currently displayed content, and then clears the displayed page. The new handwriting sent by the tablet is then received and displayed and stored.

For example, the terminal acquires the first writing handwriting and the second writing handwriting input by the user, and the corresponding first writing area S1 and the second writing area S2, as shown in FIG. 4, when the overlapping area of S1 and S2 is smaller than the pre-predetermined area When the area threshold is set, the tablet performs a merge process of S1 and S2, and the merged writing area is used as the new first writing area S1. As shown in FIG. 5, when the area of the overlapping area of S1 and S2 is greater than the preset area threshold, the tablet sends a page turning instruction to the terminal, and the terminal saves the writing handwriting in S1 in one page, and performs a page turning operation, in the new The written strokes in S2 are displayed in the blank page.

Optionally, the terminal may also store pages overlapped by S1 and S2.

In the embodiment of the present invention, the tablet obtains the written handwriting input by the user, determines whether the preset page turning condition is satisfied according to the writing handwriting, and if yes, sends a page turning instruction to the terminal, where the page turning instruction is used to indicate The terminal performs page turning for the display content, and the display content includes the content corresponding to the writing handwriting. The above method can implement page turning of the terminal according to the handwriting input by the user on the tablet, and avoid overlapping of the content displayed in the terminal.

Referring to FIG. 2, FIG. 2 is a schematic flowchart diagram of another method for page turning of a terminal according to an embodiment of the present invention. As shown in FIG. 2, the terminal page turning method may include the following steps:

S201. The tablet acquires a first writing handwriting input through the tablet, and a first writing area corresponding to the first writing handwriting.

In the embodiment of the present invention, after the tablet receives the first written handwriting input by the user, the first writing area corresponding to the first written handwriting is detected.

Specifically, the shape of the first writing area may be a polygonal area, and the specific shape of the polygon is determined by the first writing handwriting detected by the tablet, and optionally, the writing board is divided into a plurality of square areas, when the square area is When the first writing stroke is detected, the tablet records the area of the square, and the first writing area is a collection of all the square areas recorded. It should be noted that the composition of the tablet area can be 4×3, 16×9, 100×60, etc., which is specifically set by the research and development personnel, and is not limited by the embodiment of the present invention.

For example, as shown in FIG. 6a, the tablet is divided into 4×3 block areas, and the user inputs a handwriting on the tablet as “the weather is good today”, and the

block areas

604, 605, 606, 607, 608 609 is recorded by the tablet, and the first writing area is a collection of the six block areas.

S202. The tablet acquires a second writing stroke input through the tablet, and a second writing area corresponding to the second writing stroke.

Specifically, after the first writing area is determined by the tablet, it is detected whether a writing operation for the first writing area is received, and if received, the received writing hand is used as the second writing hand.

For example, as shown in FIG. 6a, the first written handwriting input by the user is the

block area

604, 605, 606, 607, 608, 609. When the tablet detects the writing handwriting input for the block area 604 again, the square is displayed. The written handwriting detected by the area 604 and the written handwriting detected in other areas thereafter are used as the second writing handwriting.

Optionally, after the writing board obtains the writing area through which the writing handwriting passes, it is determined whether the writing area of the writing handwriting of the adjacent time period passes backwards, and may be determined by whether the number of the square area is decreased, and if the number is decreased, It is determined that the writing area is reversed, and the reversed writing handwriting is used as the starting point of the second writing handwriting.

For example, the tablet is divided into 4×3 block areas, and the first written handwriting input by the user is the

block area

604, 605, 606, 607, 608, 609, and the writing input for the block area 601 is detected again when the tablet is detected again. In the case of handwriting, the number of the square area 601 is reduced with respect to the

square area

604, 605, 606, 607, 608, 609 through which the first written handwriting passes, and the tablet can determine that the writing area is reversed, and the writing of the square area 601 is detected. The handwriting detected in the handwriting and other areas thereafter is used as a writing handwriting. For example, if the user inputs a handwriting on the tablet as "day is sunny", the

square area

601, 602, 603, 604, 605, 606 is written by the tablet. Recording, the second writing area is a collection of the six square areas, as shown in Figure 6b.

S203. The tablet detects an overlapping area between the first writing area and the second writing area.

In the embodiment of the present invention, after the first writing area and the second writing area are acquired by the tablet, the overlapping area of the first writing area and the second writing area is detected, wherein the overlapping area is the first writing area and the second The intersection of the square areas contained in the writing area.

As shown in Figure 6c, the overlap region is a collection of

block regions

604, 605, 606.

S204. The tablet recognizes the writing type of the writing handwriting.

In the embodiment of the present invention, the type of writing handwriting includes characters or paintings. The determining method of the writing handwriting may specifically be: acquiring a written handwriting in the process of inputting the first writing handwriting through the tablet, determining whether the written handwriting is increasing along a preset writing direction, and if yes, determining the The type of writing handwriting is text.

Optionally, the preset writing direction is a horizontal direction, and when the tablet detects that the writing stroke input by the user is laterally increased, determining that the writing handwriting input by the user is a text.

Optionally, the preset writing direction is a vertical direction, and when the tablet detects that the writing stroke input by the user is increasing vertically, it is determined that the writing handwriting input by the user is a character.

It should be noted that the foregoing preset writing direction is only an example, and the specific one may be set by a user or a researcher.

For example, as shown in FIG. 6a, the preset writing direction is horizontal, and the tablet is divided into 4×3 square areas, and the user inputs a “good weather today” writing handwriting on the tablet, and the

square area

604, 605 606, 607, 608, 609 are recorded by the tablet, and the recording sequence of the first row of the square area detected by the tablet is 604, 605, 606, 607, 608, 609, and the direction of the written handwriting is determined to be horizontal, and preset If the writing direction is the same, it is determined that the type of writing handwriting is text. When it is detected that the recording order of the block area is 601, 603...607, 602, the tablet detects that the direction of the writing handwriting is different from the preset writing direction, and then determines that the writing handwriting is a painting.

When it is determined that the written handwriting is a text, step S205 is performed, and when it is determined that the writing handwriting is a drawing, the flow is ended.

S205. If the writing type is a character, the tablet determines whether the area of the overlapping area is greater than a preset area threshold. If yes, step S206 is performed; if not, the current process ends.

Specifically, after the overlapping area is detected by the tablet, the area of the overlapping area is calculated, and it is determined whether the area of the overlapping area is greater than a preset area threshold. If it is greater than, the tablet determines that the page needs to be turned, and then step S206 is performed; otherwise, This process can be ended. The preset area threshold may be 10 square centimeters, 20 square centimeters, etc., which may also be set by the user, which is not limited by the embodiment of the present invention.

Optionally, the tablet can determine whether the page needs to be turned over by other means, and specifically includes:

(1) The tablet directly determines whether the number of square regions included in the overlap region is greater than a preset number. If yes, step S206 is performed, and if not, the current flow is ended.

(2) the tablet acquires the area of the overlapping area, and acquires at least one of the area of the first writing area, the area of the second writing area, and the area of the writable area provided by the tablet, and the area of the overlapping area calculated by the tablet a first ratio of the writing area, and determining whether the first ratio is greater than the first preset ratio, or the tablet calculates a second ratio of the area of the overlapping area to the second writing area, and determining whether the second ratio is greater than the second ratio The preset ratio, or the tablet calculates a third ratio of the area of the overlap area to the maximum writing area provided by the tablet, and the tablet determines whether the third ratio is greater than the third preset ratio. Alternatively, the tablet combines the above determinations, such as determining whether the first ratio is greater than the first preset ratio and the second ratio is greater than the second preset ratio, and if yes, executing step S206; if not, ending the process .

S206. The tablet sends a page turning instruction to the terminal.

In the embodiment of the present invention, after the tablet determines that the area of the overlapping area is greater than the preset area threshold, the page turning instruction is sent to the terminal, the page turning instruction is used to instruct the terminal to page the display content, and the display content includes the writing handwriting Corresponding content.

After receiving the page turning instruction sent by the tablet, the terminal will save the written handwriting included in the first writing area in one page, and display a new blank page for recording the content in the second writing area.

For example, the tablet is divided into 4×3 block areas, and the user writes “writing weather is good today” in the tablet, and the tablet detects the

block areas

604, 605, 606, 607, 608, 609. . Then the user replaces the paper on the pad on the tablet, and hopes to write a "write today is sunny" writing stroke on a new page. When the user writes on the new paper "Today is sunny", the tablet is detected. The block areas occupied by "Today is sunny" are 601, 602, 603, 604, 605, and 606, which overlap with the first writing area, and the area of the overlapping area is larger than the preset area threshold, wherein the preset area threshold When the area of the two block areas is set in advance, the tablet determines that the user has replaced the paper and sends a page turning instruction to the terminal. Correspondingly, as shown in FIG. 7a, the terminal saves the written handwriting content of “Today's weather is really good” in the first writing area, and performs a page turning operation. As shown in FIG. 7b, the terminal records the user in a new blank page. The written handwriting content of "Today is sunny" in the second writing handwriting area of the input.

In the embodiment of the present invention, the tablet obtains the first writing handwriting input by the user, and the first writing area corresponding to the first writing handwriting, and then the tablet obtains the second writing handwriting, and the second writing area corresponding to the second writing handwriting, Detecting an overlapping area of the first writing area and the second writing area, determining whether an area of the overlapping area is greater than a preset area threshold, and the tablet sends a page turning instruction to the terminal. Because the user usually has a certain regularity for the writing of the text, such as writing from left to right, or writing from top to bottom, and there is no regularity for the painting, so the terminal turning method is when writing the writing is text. Good results can be achieved. When writing a handwriting, the page may be mistakenly turned over. Therefore, before the tablet sends a page turning command to the terminal, the type of the writing handwriting is also judged. When the writing handwriting is text The page flipping command is sent to avoid accidental page turning. In summary, the above method can automatically perform paged storage display of overlapping content, thereby avoiding content overlap caused by the user forgetting to press the page button.

FIG. 3 is a schematic flowchart of a page turning of a terminal according to an embodiment of the present invention, where the method may include:

The shape of the preset symbol may be a circle, a triangle, a rectangle, or the like. The preset symbol may be one or more, and the implementation of the present invention is not limited. When the tablet detects that the writing stroke input by the user includes drawing of the preset symbol, step S303 is performed.

Optionally, the preset symbol is displayed in a writable area of the tablet. On the special paper for the tablet, a preset symbol for filling in the map can be set at a specific position (such as the lower right corner), corresponding to the area where the preset symbol in the tablet is located, and the user can be prompted to finish writing on a sheet of paper. Then, by filling in the position on the paper, a page turning instruction may be sent to the terminal, and the terminal performs page turning processing on the current display page after receiving the page turning instruction.

For example, the specific area is the lower right corner of the tablet, the preset symbol is a triangle, the user puts the paper for input on the tablet, and then writes the writing stroke of "Today's weather is good" on the paper, the tablet recognition The handwriting is sent out and the recognized handwriting is sent to the matching terminal, and the terminal simultaneously displays the content input by the user on the paper. After the user finishes writing the page, he or she wants to replace the paper, and then writes the content of the next page. Then, the triangle shown in the lower right corner of the figure can be filled in. After the tablet detects the user's mapping operation, the steps are executed. S303. Preferably, when the tablet detects the triangle input by the user in the lower right corner, the content of the handwriting is not sent to the terminal, and the terminal does not display the shape drawn on the paper, but directly performs the page turning operation, but if the user is When the shape of the handwriting entered in the lower right corner is not a triangle, the tablet will transfer the content of the handwriting to the terminal, and the terminal will display the content of the handwriting without performing a page turning operation. It should be noted that the specific area may exist in any position of the tablet, or may be the writing area of the entire tablet, and may be specifically set by the user, which is not limited in the embodiment of the present invention.

The method can enable the user to input a preset symbol directly in the tablet when the paper is replaced to realize the synchronous page turning of the terminal, thereby reducing the user to press the page turning button provided in the tablet, or manually sending the page to the terminal. Page instructions to achieve the trouble of page turning.

S303. The tablet sends a page turning instruction to the terminal.

In the embodiment of the present invention, after the tablet recognizes that the written handwriting input by the user includes the preset symbol, the page turning instruction is sent to the terminal. After receiving the page turning instruction sent by the tablet, the terminal stores the current displayed page, and displays a new blank page, and displays the handwriting content of the subsequent tablet transmission under the page.

In the embodiment of the present invention, when the tablet detects the preset symbol input by the user, the page turning instruction is sent to the terminal, thereby implementing page turning of the terminal. The method of turning the page of the terminal can be enriched, and the user needs to press the page turning button provided in the tablet, or manually send a page turning instruction to the terminal to realize page turning, thereby enhancing the intelligence of the tablet.
