Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The term "comprises" and any variations thereof in the description and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

Referring to fig. 1, fig. 1 is a schematic diagram of a handwriting input device 100 according to an embodiment of the present application. The handwriting input apparatus 100 is used for communication connection with an external device 200. Specifically, the handwriting input device 100 includes a tablet 1, a pen 2, and a notebook 3. The writing tablet 1 has a surface F1. The writing pad 3 is arranged on the surface F1 of the writing pad 1. The writing book 3 includes a plurality of sheets 31 arranged in a stack. One side of the plurality of sheets 31 is fixed to the surface F1 of the tablet 1, and the plurality of sheets 31 can be turned around the side. The stylus 2 is used for writing on a sheet 31 of a writing pad 3 placed on the writing pad 1. The tablet 1 is configured to sense a touch trajectory of the stylus pen 2 when writing on the paper 31 of the notebook 3 placed on the tablet 1, recognize corresponding writing content data according to the touch trajectory, and send the writing content data to the external device 200 so that the external device 200 displays corresponding writing content. The handwriting pen 2 is a touch pen with ink such as ink, and when the handwriting pen 2 writes on the paper 31 of the notebook 3 placed on the handwriting board 1, an actual writing is formed on the paper 31, and simultaneously, an electronic handwriting corresponding to the actual writing is formed on the handwriting board 1.

Referring to fig. 2, fig. 2 is a block diagram of the handwriting board 1. The writing pad 1 comprises a processor 11 and a sensing module 13. The sensing module 13 is electrically connected to the processor 11. The sensing module 13 is disposed at a position where each sheet 31 passes during the flipping process, and a sheet identification code 131 (shown in fig. 3) is disposed at a position of each sheet 31 corresponding to the sensing module 13. When the paper 31 turns, the sensing module 13 senses the paper identification code 131 of the corresponding paper 31 and sends the sensed data to the processor 11, and the processor 11 determines the page number of the currently exposed paper 31 through the paper identification code 131. Here, the currently exposed paper 31 refers to the paper 31 that is currently facing the user and is not covered by other paper 31. It is understood that the presently exposed sheet of paper 31 may be one or two sheets of paper. If the last turned paper 31 is the first page or the last page of the writing book 3, the number of the currently exposed paper 31 is one; otherwise, the number of pages of the currently exposed paper 31 is two, including one page of the last flipped paper and one page of a paper adjacent to the last flipped paper.

Therefore, in the application, no matter one paper 31 is turned over or a plurality of papers 31 are turned over simultaneously, the page number of the currently exposed paper 31 can be accurately determined, and the page positioning is more accurate.

Specifically, in one embodiment, the paper identification code 131 is disposed in the thickness direction of each sheet of paper 31.

Specifically, in one embodiment, when the sheets 31 turn, the sensing module 13 senses the turning of each sheet 31 and generates a sensing signal. The processor 11 receives the sensing signal and determines the last turned paper 31 according to the sensing signal, and determines the page number of the currently exposed paper 31 according to the paper identification code 131 of the last turned paper 3 and the turning direction thereof.

For example, when n sheets 31 are turned in a first direction from left to right, the sensing module 13 senses the turning of each sheet 31 and generates a sensing signal, and if the sensing module 13 does not generate a new sensing signal within a preset time period, the processor 11 determines that the sheet 31 corresponding to the currently and last received sensing signal is the last sheet 31 to be turned.

Specifically, in one embodiment, when at least one sheet 31 is turned, the sensing module 13 sequentially scans the sheet id 131 of each turned sheet 31 and sequentially generates a sensing signal. The processor 11 sequentially receives the sensing signals, and processes the first received sensing signal and the last received sensing signal in the sensing signals to identify the number of pages of the first flipped sheet 31 and the last flipped sheet 31 in the at least one flipped sheet 31, and determines the page number of the currently exposed sheet 31 according to the number of pages of the last flipped sheet 31 and the flipping direction thereof when the at least one sheet 31 is flipped.

It can be understood that, in another embodiment, when at least one sheet 31 is turned over, the sensing module 13 sequentially scans the sheet id 131 of each sheet 31 in the at least one sheet 31 and sequentially generates a sensing signal. The processor 11 sequentially receives the sensing signals generated when the sensing module 13 scans the paper identification code 131 of each paper 31, and sequentially processes the sensing signals to identify the number of pages of each turned paper 31, and determines the last turned paper 31 when the turning of the paper 31 is finished, and determines the page number of the currently exposed paper 31 according to the number of pages of the last turned paper and the turning direction thereof.

For example, in one embodiment, if the number of pages of the last turned paper 31 is 3, the number of pages of the currently exposed paper 31 may be 4 and 5, or 6 and 7, and if the turning direction of the last turned paper 31 is backward, the number of pages of the currently exposed paper 31 is determined to be 4 and 5. If the turning direction of the last turned sheet 31 is the forward turning, the page numbers of the currently exposed sheets 31 are determined to be 6 and 7.

In an embodiment the tablet 1 further comprises a memory 14 and a communication unit 15. The memory 14 stores therein an electronic document. The communication unit 15 is electrically connected to the processor 11. When determining the page number of the currently exposed paper 31, the processor 11 further determines whether an electronic document corresponding to the page number of the currently exposed paper 31 is stored in the memory 14. If not, a blank electronic document is newly created, and if yes, the electronic document corresponding to the page number is called from the memory 14, and the blank document or the electronic document is sent to the external device 200 through the communication unit 15, so that the external device 200 performs corresponding display, for example, displaying a newly created blank page or displaying a corresponding electronic document, and the like.

In one embodiment, the surface F1 of the writing tablet 1 is provided with a binder 12, and the writing book 3 has a binding 33. The binding edge 33 of the notebook 3 is bound on the writing pad 1 by the binder 12, and the sheets 31 of the notebook 3 can be turned around the axis of the binder 12 to turn to the previous or next page. The sheets 31 have corner regions 311 adjacent the binder 12. The sensing module 13 is disposed on the surface F1 of the writing pad 1 and adjacent to the end of the binder 12 and the corner area 311, and the paper identification code 131 of each paper 31 is disposed in the corresponding corner area 311.

In an embodiment, the sensing module 13 is disposed on a side of the surface of the tablet 1 perpendicular to the binding edge 33 and located at one end of the binder 12, and the paper identification code 131 of the paper 31 is disposed within a detection range of the sensing module 13. Therefore, the paper identification code 131 of the paper 31 passes through the sensing module 13 during the whole turning process of the paper 31. Therefore, the sensing module 13 can sense and generate a sensing signal during the turning process of the plurality of sheets 31.

In an embodiment, the tablet 1 comprises two cover portions 14 and two sets of sensor arrays 16. The two sets of sensor arrays 16 are disposed on opposite surfaces of the two cover portions 14, respectively. The sheets 31 are spread apart, with one portion being placed on one of the sensor arrays 16 and the other portion being placed on the other sensor array 16. The two sensor arrays 16 are used for sensing a touch track of the stylus pen 2 when writing on the paper 31 on one sensor array 16, and deriving corresponding writing content data according to the touch track, and the writing content data is sent to the external device 200 to enable the external device 200 to display corresponding writing content. Wherein, after determining the page number of the paper 31 presented in front of the user, the processor 11 determines the page number of the current writing paper according to the writing position of the pen 2 on the sensor array 16 of the writing pad 1 and the page number of the paper 31 currently presented in front of the user.

In one embodiment, referring also to FIG. 3, each cover portion 14 has a writing area 141 and a border area 143. The border region 143 is "concave" and is disposed around the writing area 141. The sensor array 16 is disposed within the writing area 141. The processor 11 is disposed on the edge area 143 and electrically connected to the sensor array 16.

In an embodiment, referring to fig. 1 again, the edge area 143 is provided with a charging data interface 1431 and a video interface 1433. The charging data interface 1431 and the video interface 1433 are electrically connected to the processor 11. The charging data interface 1431 is used for charging connection or data transmission connection. The video interface 1433 is used for transmission connection of video data.

In an embodiment the tablet 1 comprises a connecting portion 17. The connecting portion 17 is located between the two cover portions 14 and connects the two cover portions 14 like a spine, so that the writing tablet 1 forms a book-shaped handwriting input device 100. The sensing module 13 is disposed at one end of the connecting portion 17 and adjacent to the binder 12.

In one embodiment, the two cover portions 14 have equal length and width dimensions. The connecting portion 17 is located between the two cover portions 14. That is, the connecting portion 17 is located on the axis of symmetry of the two face portions 14. Both ends of the connecting portion 17 extend to positions flush with both ends of the cover portion 14.

In one embodiment, the binder 12 is disposed on the connecting portion 17, and the extending direction of the binder 12 is the same as the length direction of the connecting portion 17; moreover, the binder 12 is shorter than the connecting portions 17 in the longitudinal direction, so that the connecting portions 17 form a receiving space at the position of the end of the binder 12. The sensing module 13 is disposed in the accommodating space and adjacent to an end of the binder 12.

It is understood that, in other embodiments, the sensing module 13 and the paper identification code 131 may be disposed at other suitable positions, and are not limited to the above listed positions, as long as the current page of the notebook 3 can be located.

In an embodiment, referring to fig. 3 and 4, the paper identification code 131 is formed by arranging a plurality of identification points 1311 at intervals. Each paper identification code 131 comprises a plurality of spaced identification points 1311, and the number of identification points 1311, the width of the identification points 1311 and the spacing width between the identification points 1311 contained in each paper identification code 131 are different and have uniqueness, and correspond to the number of pages of the paper 31 one by one. Therefore, the paper identification code 131 on each paper 31 is a unique identification code, and the identification code corresponds to the number of pages of the paper 31 one by one, and is combined with the turning direction of the last turning paper 31, so that the currently exposed page number of the paper 31 can be accurately positioned, and the page turning number cannot be identified due to the fact that a plurality of papers 31 are turned at one time.

Specifically, the identification points 1311 have a characteristic of reflecting the received light back, and the sensing module 13 receives the light data reflected by the identification points 1311 and generates a sensing signal. The processor 11 recognizes the paper identification code 131 according to the sensing signal, and calls a table of correspondence between preset paper identification codes and the number of sheets of paper from a database stored in the memory 14 to determine the number of sheets corresponding to the paper identification code 131, so that the page number of the currently exposed paper 31 can be determined by combining the number of sheets of paper 31 turned last and the turning direction thereof.

Specifically, in this embodiment, the identification dots 1311 are fluorescent printing ink dots. It is understood that in other embodiments, the identification dots 1311 are ink dots made of other materials with light reflection function.

Further, referring to fig. 5, fig. 6 and fig. 7, the sensing module 13 has a first sensing area 133 and a second sensing area 134. The first sensing area 133 and the second sensing area 134 are located at two positions on the writing pad 1, which are sequentially passed through when the paper 31 is turned, and when the processor 11 determines that the sensing signals of the first sensing area 133 and the second sensing area 134 are generated within a preset time after receiving the sensing signals generated by the first sensing area 133 and the second sensing area 134, the turning direction of the paper 31 of the writing book 3 is determined according to the sequence of the sensing signals received by the first sensing area 133 and the second sensing area 134.

Further, when the processor 11 receives the sensing signal of the first sensing region 133 and then receives the sensing signal of the second sensing region 134, it determines that the turning direction of the paper 31 of the written notebook 3 is to turn the page backwards. In other words, the page turning back means that the sheet 31 is turned from a position above the left cover section 14 to a position above the right cover section 14. When the processor 11 receives the sensing signal of the second sensing region 134 first and then receives the sensing signal of the first sensing region 133, it determines that the turning direction of the paper 31 of the notebook 3 is to turn the page forward. In other words, the page turning forward means that the sheet 31 is turned from a position above the right cover part 14 to a position above the left cover part 14.

Further, the first sensing region 133 and the second sensing region 134 are disposed side by side.

In some embodiments, after receiving the sensing signals generated by the first sensing area 133 and the second sensing area 134, the processor 11 further determines whether an interval between the receiving of the sensing signals generated by the first sensing area 133 and the second sensing area 134 is within a preset time (e.g., within 2 seconds), and when it is determined that the interval between the receiving of the sensing signals generated by the first sensing area 133 and the second sensing area 134 is within the preset time, determines the flipping direction of the paper 31 of the notebook 3 according to the sequence of the receiving of the sensing signals of the first sensing area 133 and the second sensing area 134. Therefore, by determining that the sensing signals generated by the first sensing area 133 and the second sensing area 134 are received successively within a preset time, misjudgment is avoided.

In some embodiments, the processor 11 determines that the turning direction of the sheet 31 of the notebook 3 is to turn the page backward (i.e. to turn to the next page) when receiving the sensing signal of the first sensing region 133 and then receiving the sensing signal of the second sensing region 134. The processor 11 determines that the turning direction of the sheet 31 of the notebook 3 is the forward page (i.e. the previous page) when receiving the sensing signal of the second sensing region 134 and then receiving the sensing signal of the first sensing region 133.

When the paper 31 is turned backward (i.e. to the next page), the paper 31 moves from the position close to the surface F1 of the tablet 1 to the position away from the surface F1 of the tablet 1, and passes through the first sensing region 133 and then the second sensing region 134. When the paper 31 is turned forward (i.e. turned to the previous page), the paper 31 moves from a position away from the surface F1 of the tablet 1 to a position close to the surface F1 of the tablet 1, and passes through the second sensing region 134 and then the first sensing region 133.

Thus, as before, the processor 11 determines that the page turning direction of the sheet 31 of the written text 3 is the page turning backward when receiving the sensing signal of the first sensing region 133 and then receiving the sensing signal of the second sensing region 134. The processor 11 determines that the turning direction of the sheet 31 of the notebook 3 is the forward turning direction when receiving the sensing signal of the second sensing region 134 and then receiving the sensing signal of the first sensing region 133.

It can be understood that, in the present embodiment, the sensing module 13 is an infrared light sensor, and the first sensing area 133 and the second sensing area 134 are two partitions of the infrared light sensor, which are disposed side by side. It is understood that in other embodiments, the first sensing region 133 and the second sensing region 134 are independent infrared light sensors disposed side by side.

In another embodiment, the sensing module 13 is a color recognition sensor, and the paper identification code 131 is a color identification point. It is understood that the color values of the color identification points of each sheet 31 of the written word 3 are different. The memory 14 stores therein a correspondence relationship between color values and the number of sheets of paper. The sensing module 13 senses the paper identification code 131 of the paper 31 and generates a sensing signal containing a paper color value. The processor 11 receives the sensing signal and determines the number of pages of the paper 31 according to the paper color value of the sensing signal. The first sensing region 133 and the second sensing region 134 are two regions of the same color recognition sensor, which are disposed side by side. It is understood that in other embodiments, the first sensing region 133 and the second sensing region 134 are independent color recognition sensors disposed side by side.

In another embodiment, the sensing module 13 includes a direction sensing unit and a page number identification unit. Wherein, the direction sensing unit may be an infrared light sensor or a color recognition sensor. The direction sensing unit is used for sensing the turning direction of the paper 31. The page identification unit may be a magnetic induction sensor. The paper identification code 131 is a magnetic powder identification point combination. It can be understood that the width of the magnetic powder mark points and the interval width between the mark points of each paper 31 of the writing book 3 are different. The page number recognition unit is used for recognizing the paper recognition code 131 of the flipping paper 31. The memory 14 stores therein a correspondence between a preset paper identification code and the number of sheets of paper. The sensing module 13 senses the paper identification code 131 of the paper 31 and generates a sensing signal. The processor 11 receives the sensing signal and determines the number of pages corresponding to the paper identification code 131 according to the sensing signal, so that the number of pages of the currently exposed paper 31 can be determined by combining the number of pages of the currently exposed paper 31 and the turning direction of the currently exposed paper 31.

It can be understood that, in other embodiments, when the writing book formed by stacking a plurality of sheets 31 is opened, the writing book has a first side located above one group of sensor arrays 16 and a second side located above the other group of sensor arrays 16, the sensing module 13 is a sensing module disposed adjacent to the first side or the second side, and the identification area of the sensing module 13 is large enough to identify all the sheet identification codes 131 of all the sheets 31 on the first side or the second side at a time, so that the page number of the uppermost sheet 31 on the first side can be known as long as the sheet identification codes 131 of all the sheets on the first side or the second side are identified. That is, when the paper 31 turns, the processor 11 determines the page number of the currently exposed paper 31 by sensing the paper identification code 131 of the currently exposed paper 31 through the sensing module 13.

It is understood that in other embodiments, the sensing module 13 is a sensing module 13 adjacent to both the first side and the second side, the sensing module 13 can identify the page turning direction, but the paper identification codes 131 of all the papers 31 can be the same, that is, the sensing module 13 identifies the number of the papers 31 turned each time and the page turning direction to determine the page number of the paper 31 finally positioned uppermost. That is, when the sheets 31 are turned, the processor 11 determines the number of pages of the turned sheets 31 by sensing the sheet identification codes 131 of the turned sheets 31 through the sensing module 13, and determines the number of pages of the currently exposed sheets 31 according to the number of pages of the turned sheets 31.

In this application, through set up on handwriting pad 1 when the position that paper 31 turned over the in-process and pass through with response module 13, when at least a paper 31 turned over, then can pass through response module 13, processor 11 then confirms the page number of the paper 31 that exposes at present through the sensing signal that response module 13 produced, and the page location is more accurate.

The processor 11 may be a central processing unit, a single chip, a digital signal processor, a microcontroller, or the like. The memory 14 may be a solid state memory, a memory card, or the like. The communication unit 15 can be a wireless module such as a bluetooth module, a WIFI module, a GPRS communication module, and can also be a wired interface unit such as a USB interface and a fire wire interface.

The first sensing region 133 and the second sensing region 134 are not specific to a particular sensing module, but are named as the first and the second for the convenience of distinguishing.

The external device 200 may be a mobile phone, a tablet computer, or the like, and is installed with application software (APP) that is matched with the handwriting input device 100.

Please refer to fig. 8, which is a flowchart illustrating a page positioning method according to an embodiment of the present application. The page positioning method is used in the handwriting input device 100, the handwriting input device 100 includes a handwriting board 1 and a writing book 3 placed on the surface of the handwriting board 1, the writing book 3 includes a plurality of paper 31, the handwriting board 1 includes an induction module 13, the induction module 13 is disposed at a position where each paper 31 passes through in the turning process, a paper identification code 131 is disposed at a position of each paper 31 corresponding to the induction module 13, and the induction module 13 induces the paper identification code 131 of the corresponding paper 31 and generates an induction signal. The page positioning method comprises the following steps.

Step S810: when the paper 31 turns, the sensing module 13 senses the paper identification code 131 of the corresponding paper 31 and generates a sensing signal.

Specifically, in one embodiment, when the paper 31 turns, the sensing module 13 senses the paper identification code 131 of the currently exposed paper 31 and generates a sensing signal.

Step S820: and determining the page number of the currently exposed paper 31 according to the sensing signal.

Specifically, in an embodiment, when the identification area of the sensing module 13 is large enough to identify all the paper identification codes 131 of all the paper 31 on the first side or the second side at a time, the sensing module 13 identifies the paper identification codes 131 of all the paper on the first side or the second side, so as to know the page number of the topmost paper 31 on the side. At this time, after the turning motion of the paper 31 is completed, the sensing module 13 senses the paper identification codes 131 of all the papers on the first side or the second side and generates a sensing signal. The processor 11 determines the page number of the currently exposed paper 31 according to the sensing signal.

Specifically, in another embodiment, the sensing module 13 is a sensing module 13 adjacent to both the first side and the second side, the sensing module 13 can identify the page turning direction, but the paper identification codes 131 of all the paper 31 can be the same, that is, the sensing module 13 identifies the number of the turned paper 31 and the page turning direction each time to determine the page number of the paper 31 finally positioned at the top. That is, when the sheets 31 are turned, the processor 11 determines the number of pages of the turned sheets 31 by sensing the sheet identification codes 131 of the turned sheets 31 through the sensing module 13, and determines the number of pages of the currently exposed sheets 31 according to the number of pages of the turned sheets 31.

Specifically, in another embodiment, the last turned sheet 31 is determined according to the sensing signal, and the page number of the currently exposed sheet 31 is determined according to the sheet identification code 131 of the last turned sheet 31 and the turning direction thereof.

Specifically, in an embodiment, the sensing areas corresponding to the sensing module 13 are a first sensing area 133 and a second sensing area 134, and the determining of the flipping direction of the last flipped paper 31 includes:
