Note that the contents displayed on the terminal are the same as those in the paper on the tablet.
Specifically, the writing handwriting includes a first writing handwriting and a second writing handwriting, the handwriting board detects the writing handwriting input by the user, if no new writing handwriting is detected in the time interval T0, the written handwriting is determined as the first writing handwriting, and a first writing area S1 corresponding to the first writing handwriting is obtained. The specific determination manner of S1 may be to obtain a leftmost abscissa value X0, a rightmost abscissa value X1, a lowermost ordinate value Y0, and a uppermost ordinate value Y1 of the first handwriting; a rectangular region having the coordinates (X0, Y0), (X0, Y1), (X1, Y0), (X1, Y1) as vertices is the writing region S1. After the time interval T0, if the writing input by the user is detected again and no new writing is detected in the next time interval T0, the writing detected again is determined as the second writing, and the second writing area S2 corresponding to the second writing is obtained.
It should be noted that the time interval T0 may be 3 seconds, 5 seconds, and the like, and may be specifically set by a developer when the developer leaves a factory, or may be set by a user, which is not limited in the embodiment of the present invention.
S102, judging whether preset page turning conditions are met or not by the handwriting board according to the handwriting, and if yes, executing a step S103; if not, the process is ended.
Specifically, the handwriting pad detects whether the handwriting of the user overlaps, and if the area of the overlapping part is larger than a preset area threshold value, it is determined that the handwriting meets a page turning condition, and the method specifically comprises the following steps: the handwriting board detects whether the area of the overlapping area of the first writing area S1 and the second writing area S2 is larger than a preset area threshold, if so, the handwriting board determines that the handwriting meets the page turning condition, and step S103 is executed.
The preset area threshold may be 10 square centimeters, 20 square centimeters, or the like, and may be specifically set by a developer or modified by a user, which is not limited in the embodiment of the present invention.
In some possible embodiments, if the area of the overlapping area of the first writing region S1 and the second writing region S2 is smaller than or equal to the preset area threshold, the tablet may perform a merging process on S1 and S2, regard the merged writing region as a new first writing region S1, continue to acquire a new second writing region S2, and determine whether the preset page turning condition is satisfied according to the area of the overlapping area of the new first writing region S1 and the new second writing region S2.
Optionally, the handwriting board may also detect the number of intersection points of the handwriting of the user, and if the number of intersection points of the handwriting is greater than a preset number threshold, it is determined that the handwriting satisfies the page turning condition, which may specifically include: and the handwriting board detects whether the number of the intersection points of the first handwriting and the second handwriting is larger than a preset number threshold, if so, the handwriting board determines that the handwriting meets page turning conditions, and step S103 is executed.
The preset number threshold may be 10, 20, or the like, and may be specifically set by a developer or modified by a user, which is not limited in the embodiment of the present invention.
In some possible implementations, if the number of the intersection points of the first writing trace and the second writing trace is less than or equal to the preset number threshold, the handwriting board may combine the first writing trace and the second writing trace.
S103, the handwriting board sends a page turning instruction to the terminal.
In the embodiment of the invention, after the handwriting board judges that the handwriting of the user meets the page turning condition, a page turning instruction is sent to the terminal, the page turning instruction is used for indicating the terminal to turn pages for the display content, and the display content comprises the writing content corresponding to the handwriting.
Correspondingly, after receiving the page turning instruction sent by the handwriting board, the terminal stores the currently displayed content and then clears the displayed page. And then receiving the new handwriting sent by the handwriting board, and displaying and storing the new handwriting.
For example, the terminal acquires the first writing script and the second writing script input by the user, and the corresponding first writing area S1 and second writing area S2, as shown in fig. 4, when the area of the overlapping area of S1 and S2 is smaller than the preset area threshold, the tablet merges S1 and S2, and the merged writing area is used as a new first writing area S1. When the area of the overlapped area of S1 and S2 is larger than the preset area threshold, the handwriting pad sends a page turning instruction to the terminal, the terminal stores the writing in S1 in one page, and performs a page turning operation, and the writing in S2 is displayed in a new blank page, as shown in FIG. 5.
Optionally, the terminal may further store the page where S1 overlaps S2.
In the embodiment of the invention, the handwriting board acquires the handwriting input by the user, whether the handwriting meets the preset page turning condition is judged according to the handwriting, if yes, a page turning instruction is sent to the terminal and used for indicating the terminal to turn pages for the display content, and the display content comprises the content corresponding to the handwriting.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating another method for turning pages of a terminal according to an embodiment of the present invention. As shown in fig. 2, the terminal page turning method may include the steps of:
s201, a first writing script input through a writing board and a first writing area corresponding to the first writing script are obtained through the writing board.
In the embodiment of the invention, after the handwriting board receives the first writing handwriting input by the user, the first writing area corresponding to the first writing handwriting is detected.
Specifically, the shape of the first writing area may be a polygonal area, the specific shape of the polygon is determined by the first writing trace detected by the writing pad, optionally, the writing pad is divided into a plurality of square areas, when the first writing trace is detected on the square area, the writing pad records the square area, and the first writing area is a set of all recorded square areas. It should be noted that the composition of the square area of the handwriting pad may be 4 × 3, 16 × 9, 100 × 60, etc., which is specifically set by the developer, and the embodiment of the present invention is not limited thereto.
For example, as shown in fig. 6a, the handwriting board is divided into 4 × 3 square areas, and a piece of handwriting input by the user on the handwriting board is "today's weather is really good", the square areas 604, 605, 606, 607, 608, 609 are recorded by the handwriting board, and the first writing area is a collection of the 6 square areas.
S202, the handwriting board obtains a second handwriting input through the handwriting board and a second writing area corresponding to the second handwriting.
Specifically, after the handwriting board determines a first writing area, whether a writing operation for the first writing area is received or not is detected, and if the writing operation is received, the received writing is used as a second writing.
For example, as shown in fig. 6a, the first writing input by the user is a square area 604, 605, 606, 607, 608, 609, and when the writing input for the square area 604 is detected again by the tablet, the writing detected by the square area 604 and the writing detected by other areas later are taken as the second writing.
Optionally, after the handwriting board acquires the writing area through which the writing trace passes, whether the writing area through which the writing trace passes in the adjacent time period backs up is determined, specifically, whether the number of the square area is reduced or not is determined, if the number is reduced, the writing area is determined to back up, and the reversed writing trace is used as the starting point of the second writing trace.
For example, the handwriting board is divided into 4 × 3 square areas, the first writing script input by the user is the square areas 604, 605, 606, 607, 608, 609, when the handwriting board detects the writing script input for the square area 601 again, the number of the square area 601 is reduced relative to the square areas 604, 605, 606, 607, 608, 609 through which the first writing script passes, the handwriting board can determine that the writing area is reversed, and then the writing script detected by the square area 601 and the writing scripts detected by other areas are taken as writing scripts, for example, if the user inputs a piece of handwriting on the handwriting board, "today is sunny", the square areas 601, 602, 603, 604, 605, 606 are recorded by the handwriting board, and the second writing area is the set of the 6 square areas, as shown in fig. 6 b.
S203, detecting an overlapping area of the first writing area and the second writing area by the handwriting board;
in the embodiment of the invention, after the handwriting board acquires the first writing area and the second writing area, an overlapping area of the first writing area and the second writing area is detected, wherein the overlapping area is an intersection of square areas included in the first writing area and the second writing area.
As shown in fig. 6c, the overlap region is a set of square regions 604, 605, 606.
And S204, recognizing the writing type of the handwriting by the handwriting board.
In the embodiment of the invention, the type of handwriting comprises characters or paintings. The method for judging the handwriting specifically comprises the steps of acquiring the written handwriting in the process of inputting the first handwriting through the handwriting board, judging whether the written handwriting is increased progressively along a preset writing direction, and if so, determining that the type of the written handwriting is a character.
Optionally, the preset writing direction is a horizontal direction, and when the handwriting board detects that the writing input by the user is increased horizontally, the writing input by the user is determined to be a character.
Optionally, the preset writing direction is a longitudinal direction, and when the handwriting board detects that the writing input by the user is increased longitudinally, the writing input by the user is determined to be a character.
It should be noted that the preset writing direction is only an example, and may be specifically set by a user or a developer.
For example, as shown in fig. 6a, the preset writing direction is a horizontal direction, the handwriting board is divided into 4 × 3 square areas, the user inputs a writing trace of "today's weather is really good" on the handwriting board, the square areas 604, 605, 606, 607, 608, 609 are recorded by the handwriting board, and the handwriting board detects that the recording sequence of the first row of square areas is 604, 605, 606, 607, 608, 609 determines that the direction of the writing trace is a horizontal direction, and is consistent with the preset writing direction, and determines that the type of the writing trace is a character. When the recording sequence of the square areas is detected to be 601, 603 … 607, 602, and the direction of the handwriting detected by the handwriting board is different from the preset writing direction, the handwriting is determined to be drawing.
If the writing is judged to be a character, step S205 is executed, and if the writing is judged to be a drawing, the flow is ended.
S205, if the writing type is a character, the handwriting board judges whether the area of the overlapping area is larger than a preset area threshold value, if so, the step S206 is executed; if not, the process is ended.
Specifically, after the handwriting board detects the overlap area, the area of the overlap area is calculated, and whether the area of the overlap area is larger than a preset area threshold is judged, if so, the handwriting board determines that page turning is needed, and then step S206 is executed, otherwise, the process may be ended. The preset area threshold may be 10 square centimeters, 20 square centimeters, or the like, and may also be set by the user, which is not limited in the embodiment of the present invention.
Optionally, the handwriting board may further determine whether to turn pages in other manners, which may specifically include:
(1) the handwriting board directly determines whether the number of square areas included in the overlapping area is greater than a preset number, if so, step S206 is executed, and if not, the process is ended.
(2) The handwriting board obtains the area of the overlapping area, and obtains 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 handwriting board, the handwriting board calculates the first ratio of the area of the overlapping area to the first writing area, and judges whether the first ratio is larger than the first preset ratio, or the handwriting board calculates the second ratio of the area of the overlapping area to the second writing area, and judges whether the second ratio is larger than the second preset ratio, or the handwriting board calculates the third ratio of the area of the overlapping area to the maximum writing area provided by the handwriting board, and the handwriting board judges whether the third ratio is larger than the third preset ratio. Or, the handwriting board combines the above determinations, and determines whether the first ratio is greater than a first preset ratio and whether the second ratio is greater than a second preset ratio, if so, step S206 is executed, and if not, the process is ended.
S206, the handwriting board sends a page turning instruction to the terminal.
In the embodiment of the invention, after the handwriting board determines that the area of the overlapping area is larger than the preset area threshold, a page turning instruction is sent to the terminal, the page turning instruction is used for indicating the terminal to turn pages for the display content, and the display content comprises the content corresponding to the handwriting.
After receiving the page turning instruction sent by the handwriting board, the terminal stores the handwriting included in the first writing area in one page, and displays a new blank page for recording the content in the second writing area.
For example, the handwriting board is divided into 4 × 3 square areas, the user writes a handwriting of "today's weather is good" in the handwriting board, and the handwriting board detects the square areas 604, 605, 606, 607, 608, 609. Then, the user changes the paper padded on the handwriting board, hopes to write the handwriting of 'today is sunny' on a new piece of paper, after the user writes the handwriting of 'today is sunny' on the new paper, the handwriting board detects that the square areas occupied by the 'today is sunny' are 601, 602, 603, 604, 605 and 606, the square areas overlap with the first writing area, and the area of the overlapping area is larger than a preset area threshold value, wherein the preset area threshold value is preset to be the area of two square areas, the handwriting board judges that the user has changed the paper, and sends a page turning instruction to the terminal. Correspondingly, as shown in fig. 7a, the terminal stores the writing contents of "today's weather is good" in the first writing area, and performs a page turning operation, as shown in fig. 7b, the terminal records the writing contents of "today is sunny" in the second writing area input by the user in a new blank page.
In the embodiment of the invention, a handwriting board acquires a first writing handwriting input by a user and a first writing area corresponding to the first writing, then the handwriting board acquires a second writing and a second writing area corresponding to the second writing, an overlapping area of the first writing area and the second writing area is detected, whether the area of the overlapping area is larger than a preset area threshold value or not is judged, and the handwriting board sends a page turning instruction to a terminal. Because the user has certain regularity for writing of characters under normal conditions, such as writing from left to right or writing from top to bottom, and no regularity can be obtained for painting, the terminal page turning method can achieve a good effect when the handwriting is the characters, and the situation of mistaken page turning can occur when the handwriting is the painting, so that before the handwriting board sends a page turning instruction to the terminal, the type of the handwriting is judged, and the page turning instruction is sent when the handwriting is the characters, so that the situation of mistaken page turning can be avoided. In conclusion, the method can automatically perform paging storage display on the overlapped contents, and avoids the phenomenon of content overlapping caused by the fact that a user forgets to press a paging key.
Referring to fig. 3, a schematic flow chart of page turning of a terminal according to an embodiment of the present invention is shown, where the method includes:
s301, the handwriting board obtains the handwriting input through the handwriting board.
In the embodiment of the invention, the handwriting board can acquire the handwriting input by the user.
S302, the handwriting board identifies whether the handwriting input through the handwriting board contains preset symbols.
In the embodiment of the present invention, the preset symbol may be set at a specific position in the handwriting board, such as the lower right corner, which may be preset by a developer or may be set by a user, which is not limited in the embodiment of the present invention. The shape of the preset symbol may be a circle, a triangle, a rectangle, etc., and the preset symbol may be one or more, which is not limited in the embodiments of the present invention. When the handwriting pad detects that the handwriting input by the user includes the depiction of the preset symbol, step S303 is executed.
Optionally, the preset symbol is displayed in a writable area of the tablet. On the special paper for the handwriting board, a preset symbol for filling in a drawing can be arranged at a specific position (such as the lower right corner), and a region where the preset symbol is located in the handwriting board can prompt a user to fill in the drawing at the position on the paper after writing on a page of paper is finished, so that a page turning instruction can be sent to the terminal, and the terminal performs page turning processing on a currently displayed page after receiving the page turning instruction.
For example, the specific area is the lower right corner of the handwriting board, the preset symbol is a triangle, the user pads paper for inputting on the handwriting board, then writes a handwriting of "today is good" on the paper, the handwriting board recognizes the handwriting and sends the recognized handwriting to a terminal matched with the handwriting board, and the terminal synchronously displays the content input by the user on the paper. After the user finishes writing on the page of paper, the user wants to change the paper, and then writes the next page of content, the triangle shown in the lower right corner of the drawing can be filled, and after the handwriting board detects the drawing filling operation of the user, step S303 is executed. Preferably, when the handwriting board detects that the triangle input by the user at the lower right corner is not sent to the terminal, the terminal does not display the shape drawn on the paper and directly executes the page turning operation, but if the shape of the handwriting input by the user at the lower right corner is not the triangle, the handwriting board transmits the content of the handwriting to the terminal, and the terminal displays the content of the handwriting without executing the page turning operation. It should be noted that the specific area may be present at any position of the handwriting board, may be a writing area of the entire handwriting board, and may be specifically set by the user, and the embodiment of the present invention is not limited thereto.
The method can ensure that a user can directly input a preset symbol in the handwriting board to realize synchronous page turning of the terminal when the user changes the paper, thereby reducing the trouble that the user presses a page turning key provided in the handwriting board or manually sends a page turning instruction to the terminal to realize page turning.
S303, the handwriting board sends a page turning instruction to the terminal.
In the embodiment of the invention, after the handwriting input by the user is recognized by the handwriting board to contain the preset symbol, a page turning instruction is sent to the terminal. And after receiving a page turning instruction sent by the handwriting board, the terminal stores the current display page, displays a new blank page and displays the handwriting content transmitted by the subsequent handwriting board under the page.
In the embodiment of the invention, when the handwriting board detects the preset symbol input by the user, the page turning instruction is sent to the terminal, so that the page turning of the terminal is realized. The method can enrich the page turning mode of the terminal, and does not need a user to press a page turning key provided in the handwriting board or manually send a page turning instruction to the terminal to turn pages, thereby enhancing the intelligence of the handwriting board.
The terminal page turning device according to the embodiment of the present invention will be described in detail with reference to fig. 8.
