The handwriting pad 100 generates writing handwriting by sensing the writing operation of the stylus 200. It is understood that, in an embodiment, the tablet 100 is disposed on the electronic apparatus 500, and the tablet 100 is an input device on the electronic apparatus 500 and is controlled by the electronic apparatus 500.

Please refer to fig. 2-3, wherein fig. 2 is a schematic structural diagram of a handwriting device 300 according to an embodiment of the present application, and fig. 3 is a schematic block diagram of the handwriting board 100 in fig. 2. As shown in fig. 2, the stylus pen 200 is detachably mounted on the tablet 100. When writing is needed, the writing pen 200 is removed from the writing pad 100.

The writing pad 100 includes a touch pad 10 and a processor 20, and the touch pad 10 is electrically connected to the processor 20. The touch panel 10 includes a writing area 11 and an operation area 12, and the operation area 12 is located on one side of the writing area 11. The touch panel 10 senses writing operation of the stylus pen 200 in response to the writing area 11 and generates first touch coordinate data, and also generates an adjustment instruction in response to a first specific operation received by the operating area 12. The processor 20 obtains the first touch coordinate data, generates a writing trace according to the first touch coordinate data, and adjusts the writing trace according to the adjustment instruction in the process of generating the writing trace. In this way, the writing device 300 provided by the present application can perform corresponding adjustment on the writing handwriting during the writing process.

The Processor 20 may be a Central Processing Unit (CPU), other general-purpose Processor, a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field-Programmable Gate Array (FPGA) or other Programmable logic device, a discrete Gate or transistor logic device, a discrete hardware component, or the like. The general purpose processor may be a microprocessor or the processor may be any conventional processor or the like, the processor being the control center for the tablet 100 and connecting the various parts of the entire tablet 100 using various interfaces and lines.

In the present embodiment, the writing area 11 is provided with a display screen, that is, the writing area 11 has a display function, that is, the writing area 11 can also display the generated writing. The operation area 12 is not provided with a display screen, has no display function, and is only used for responding to the first specific operation input by the user. In other embodiments, the operation area 12 is also provided with a display screen, which has a display function, that is, the entire touch panel 10 is a touch display screen, and one part of the touch display screen is divided into a writing area 11, and the other part is divided into the operation area 12. The specific positional relationship between the writing area 11 and the operation area 12 is not limited herein, and preferably, the operation area 12 is located on the left side of the writing area 11 to facilitate writing.

Specifically, the first specific operation includes, but is not limited to, clicking the operation region 12, touching the operation region 12 with a single finger and sliding from one side of the operation region 12 to the other side (i.e., single-finger sliding), touching the operation region 12 with two fingers and sliding from one side of the operation region 12 to the other side (i.e., double-finger sliding), and the like. The adjusting instruction comprises a handwriting color adjusting instruction, a handwriting type adjusting instruction or a handwriting thickness adjusting instruction. Wherein the handwriting types include but are not limited to ball-point pen handwriting, sign pen handwriting, brush pen handwriting, pencil handwriting, and the like.

It is to be understood that each adjustment instruction corresponds to a different first specific operation. For example, the handwriting type can be changed by clicking the operation area 12; the color of the handwriting can be changed by sliding a single finger on the operating area 12; the thickness of the handwriting can be changed by double-finger sliding on the operating area 12. Of course, the corresponding relationship between each adjustment command and the first specific operation is not limited to this, and may be set according to specific requirements, for example, the handwriting color may also be changed by sliding the two fingers.

It should be noted that in a specific design, the type of handwriting can be changed by clicking different positions on the operation area 12; the thickness of the handwriting can be gradually thicker along with sliding or gradually thinner along with sliding; the handwriting color can be gradually changed into other different colors along with sliding, and the specific transformation corresponding relation is not specifically limited herein.

Referring to fig. 4 again, fig. 4 is a schematic diagram illustrating a handwriting pen 200 according to an embodiment of the present application writing on the handwriting board 100. When the writing pen 200 is used for writing, a writing paper 400 may be covered on the writing area 11, a real handwriting (as shown by a in fig. 6) may be formed on the writing paper 400, and the writing pad 100 may be driven to form a writing handwriting corresponding to the real handwriting at the same time. In this embodiment, the touch panel 10 is a capacitive touch panel, and is configured to sense a capacitance change generated by the contact of the stylus pen 200 or a finger of a user to determine a position where touch occurs, so as to obtain first touch coordinate data.

Referring again to fig. 3, in some embodiments, the touchpad 10 may include a touch sensor 11 and a touch controller 12. The touch sensor 11 is configured to sense contact between the stylus pen 200 and/or the user's finger and the touch pad 10 to generate a corresponding touch sensing signal, and the touch controller 12 generates first touch coordinate data according to the received touch sensing signal, and generates an adjustment instruction according to the first touch coordinate data from the operation area 12 when it is determined that the first touch coordinate data is from the operation area 12. When the touch controller 12 determines that the first touch coordinate data is from the writing area 11, the touch controller 12 directly sends the generated first touch coordinate data from the writing area 11 to the processor 20. Specifically, the number of the touch sensors 11 is multiple, each touch sensor 11 corresponds to a coordinate, the touch controller 12 determines the touch sensor 11 generating the touch sensing signal after receiving the touch sensing signal, and further obtains first touch coordinate data according to the coordinate corresponding to the touch sensor 11. When the first touch coordinate data is from the operation area 12, the touch controller 12 further generates a corresponding adjustment instruction according to the acquired first touch coordinate data. The touch controller 12 further determines a first specific operation including information such as a touch action and a touch trajectory according to the position change of each coordinate in the first touch coordinate data, and determines a corresponding adjustment instruction according to the first specific operation. For example, the touch controller 12 prestores different corresponding relationships between the first specific operation and the adjustment instruction, and when the touch controller 12 determines that the acquired set of the first touch coordinate data is from the operation area 12 and determines the first specific operation according to the first touch coordinate data, the adjustment instruction corresponding to the first specific operation is further determined.

It can be understood that, in this embodiment, in order to prevent the erroneous touch operation caused by the non-pen-touch signals of the finger, the palm, and the like, the writing area 11 of the touch pad 10 may be set to shield the non-pen-touch signals except the touch sensing signal generated by the stylus pen 200, so as to improve the accuracy of detecting the pen-touch signals and optimize the touch writing experience. In other embodiments, the area of the touch panel 10 corresponding to the writing area 11 may further include an electromagnetic induction screen, and the electromagnetic induction screen generates the first touch coordinate data by sensing an electromagnetic signal of the stylus pen.

Referring to fig. 5, in some embodiments, the touch panel 10 further includes a plurality of induction coils 101 arranged in an array, the plurality of induction coils 101 respectively correspond to a coordinate, and the attributes of the plurality of induction coils 101 are different, where the attribute of each induction coil 101 includes a cross-sectional area, a number of turns, an induction intensity, and the like of each induction coil 101. When the stylus pen 200 contacts one of the induction coils 101, the attribute of the contacted induction coil 101 is sensed and the corresponding induction coil 101 coordinate is identified according to the attribute to generate the second touch coordinate data.

In other embodiments, as shown in FIG. 3, the tablet 100 further comprises a wireless communication module 30. The wireless communication module 30 is electrically connected to the processor 20 and configured to receive second touch coordinate data sent by the stylus 200, and the processor 20 is configured to combine the first touch coordinate data with the second touch coordinate data and generate a writing trace according to the combined touch coordinate data, so that accuracy of coordinates of each touch point of the stylus 200 can be improved, accuracy of generation of the writing trace can be improved, and the writing trace can be optimized.

In this embodiment, the wireless communication module 30 is a bluetooth low energy module, and the wireless communication module 30 may be integrated in the processor 20. In other embodiments, the wireless communication module 30 may also be other chips with communication functions, such as a WiFi chip. The wireless communication module 30 may also be a stand-alone communication module.

Referring to fig. 6 again, fig. 6 is a schematic diagram illustrating the generation of three-dimensional handwriting of the handwriting board 100 disclosed in the present application. The wireless communication module 30 is further configured to transmit the adjusted handwriting to the electronic device 500, so as to trigger the electronic device 500 to generate a corresponding three-dimensional handwriting (shown in b). Wherein, the color, thickness or handwriting type of the three-dimensional handwriting is different from the real handwriting.

In the present embodiment, when the user performs a writing operation in the writing area 11 with the stylus 200 and performs a sliding operation in the operation area 12 with a finger, the writing trace dynamically adjusts the thickness of the trace as the sliding position of the user in the operation area 12 changes. For example, when the user performs a slide-up operation on the operation area 12, the writing gradually adjusts the thickness of the writing as the user's finger slides up to different positions of the operation area 12 at different times during the slide-up operation. I.e. the handwriting thickness is related to the sliding direction and the position of the user's finger in the operation area 12.

In other embodiments, the touchpad 10 is further responsive to a second specific operation received by the writing area 11 and generates modification instructions. The processor 20 is further configured to modify the generated handwriting according to the modification instruction. When the generated handwriting has formed a pattern, the touch panel 10 responds to the second specific operation and generates the modification instruction for modifying the generated pattern. In this embodiment, the modification instruction includes a shading modification instruction or a coloring modification instruction. In other embodiments, the modification instruction may further include smearing or erasing the generated handwriting, and the like.

The second specific operation includes, but is not limited to, touching and moving the writing on the writing area 11 with a single finger, touching and moving the writing on the writing area 11 with a double finger, and the like. The second specific operation corresponding to each modification instruction is different, for example, the drawn line can be modified into a shading effect by touching the generated handwriting with a single finger and moving along the track of the handwriting, and the drawn pattern can be colored by touching the generated handwriting with two fingers and moving in the corresponding pattern area. Of course, the second specific operation corresponding to each modification instruction may be set according to specific design requirements, and is not limited herein.

Similarly, when the touch panel 100 includes the touch sensor 11 and the touch controller 12, after the touch controller 12 receives the touch sensing signal, the touch sensor 11 generating the touch sensing signal is determined, and the coordinate corresponding to the touch sensor 11 is further obtained to obtain the first touch coordinate data. When the touch controller 12 determines that the touch area is located in the writing area 11 according to the first touch coordinate data, it further determines a second specific operation including information such as a touch action and a touch trajectory according to a position change of each coordinate in the first touch coordinate data, and determines a corresponding modification instruction according to the second specific touch operation.

Referring to fig. 7 again, fig. 7 is a schematic diagram of three-dimensional handwriting generation disclosed in another embodiment of the present application. The wireless communication module 30 is further configured to transmit the modified handwriting to the electronic device 500, so as to trigger the electronic device 500 to generate a corresponding three-dimensional handwriting (shown in c). Wherein, the color, thickness or handwriting type of the three-dimensional handwriting is different from the real handwriting.

It can be understood that the handwriting board 100 may also transmit the handwriting and the adjustment instruction and/or the modification instruction to the electronic device 500 in real time, such as a smart phone, a tablet computer, and the like, so as to trigger the electronic device 500 to adjust and/or modify the handwriting according to the adjustment instruction and/or the modification instruction, and generate a corresponding three-dimensional handwriting, thereby implementing real-time display of the three-dimensional handwriting on a screen of the electronic device 500, and implementing digital storage of the three-dimensional handwriting.

In order to distinguish the second specific operation input by the user's finger from the writing operation of the stylus pen 200 to avoid confusion between a modification instruction and a handwriting generation, in some embodiments, the touch controller 12 is further configured to determine whether a contact area of the writing area 11 of the touchpad 10 when generating the first touch coordinate data is greater than a preset value, when the contact area is greater than the preset value, the touch controller 12 determines that the input is currently performed by the user's finger, and the touch controller 12 generates the modification instruction according to the first touch coordinate data. When the contact area is not greater than the preset value, the touch controller 12 determines that the input is currently performed by the stylus pen 200, and the touch controller 12 does not process the generated first touch coordinate data, that is, directly sends the generated first touch coordinate data to the processor 20. Wherein the preset value is larger than the maximum area of contact between the stylus pen and the touch panel 10 and smaller than the minimum area of contact between the user's finger and the touch panel 10. Of course, in other embodiments, if the stylus pen 200 generates the touch signal by other methods, this embodiment may be omitted.

Wherein, the touch controller 12 can determine the contact area between the stylus pen 200 or the user's finger and the touch pad 10 according to the number of touch coordinates of the user's finger or the stylus pen 200 at a single touch point.

Referring to fig. 3 again, in order to prevent the erroneous touch operation caused by the non-pen-touch signal of the finger, palm, etc. during the process of generating the handwriting, the handwriting pad 100 further includes a switch 40. The switch 40 is electrically connected to the processor 20. The processor 20 is further configured to receive a switch signal generated by the switch 40 in response to the trigger, and when the processor 20 receives the first switch signal, the processor 20 controls the touch panel 10 to respond to the second specific operation received by the writing area 11. In this embodiment, the first switching signal is a high-level signal, but it is understood that in other embodiments, the first switching signal may also be a low-level signal.

Specifically, in one embodiment, the switch 40 may be connected to the positive terminal of the power supply through a resistor, the other terminal of the switch is connected to the ground, the processor 20 is connected to a node between the switch 40 and the resistor, and when the switch 40 is turned on or off, the processor 20 will receive a low signal and a high signal, respectively, so as to control the second specific operation of the touch pad 10 responding to the input of the user's finger through the writing area 11 according to the received signals. The switch 40 may be a physical switch, such as a key switch or a toggle switch disposed on a side of the casing of the tablet 100. In other embodiments, the switch 40 may also be a virtual switch, for example, by forming a touch icon and displaying it on the touch panel 10, and by sending different switch signals to the processor 20 in response to a touch.

In addition, in some embodiments, when the touch panel 10 also responds to a third specific operation received by the operating area 12 and the writing area 12 of the touch panel 10 does not receive a writing operation, a control instruction is generated according to the third specific operation. The processor 20 also controls the handwriting board 100 to execute corresponding control according to the control instruction.

Wherein the third specific operation includes, but is not limited to, clicking the operation area 12, double clicking the operation area 12, touching the operation area 12 with a single finger and sliding from one side of the operation area 12 to the other side (i.e., single finger sliding), touching the operation area 12 with a double finger and sliding from one side of the operation area 12 to the other side (i.e., double finger sliding), and the like. The control instruction includes a new page number instruction, a save page number instruction, a page turning instruction, or a communication connection establishment (for example, a bluetooth connection with the stylus pen 200 or the electronic device 500) instruction, and the like. It is to be understood that the corresponding relationship between each control instruction and the third specific operation is not limited herein, and each control instruction corresponds to a different third specific operation, for example, a single-finger upward sliding corresponds to an upward page-turning instruction, a single-finger downward sliding corresponds to a downward page-turning instruction, a double-click corresponds to a communication connection establishment instruction, and the like.

Please refer to fig. 8, which is a flowchart illustrating a writing method according to an embodiment of the present application. The writing method is applied to a writing pad 100, and the writing pad 100 comprises a touch pad 10 and a processor 20 electrically connected with the touch pad 10. The touch panel 10 includes a writing area 11 and an operation area 12 located at one side of the writing area 11, and the writing method includes the steps of:

step S801, acquiring first touch coordinate data generated by the touch panel 10 in response to the writing operation sensed by the writing area, and acquiring an adjustment instruction generated by the touch panel 10 in response to the first specific operation received by the operating area.

Specifically, the first specific operation includes, but is not limited to, clicking the operation area 12, touching the operation area 12 with a single finger and sliding from one side of the operation area 12 to the other side (i.e., single-finger sliding), touching the operation area 12 with two fingers and sliding from one side of the operation area 12 to the other side (i.e., double-finger sliding), and the like.

And S802, generating writing according to the first touch coordinate data.

And S803, adjusting the handwriting according to the adjusting instruction in the process of generating the handwriting.

The adjusting instruction comprises a handwriting color adjusting instruction, a handwriting type adjusting instruction or a handwriting thickness adjusting instruction. Wherein the handwriting types include but are not limited to ball-point pen handwriting, sign pen handwriting, brush pen handwriting, pencil handwriting, and the like.

It is understood that each adjustment instruction corresponds to a different first specific operation. For example, the handwriting type can be changed by clicking the operation area 12; the color of the handwriting can be changed by sliding a single finger on the operating area 12; the thickness of the handwriting can be changed by double-finger sliding on the operating area 12. Of course, the corresponding relationship between each adjustment command and the first specific operation is not limited to this, and may be set according to specific requirements, for example, the handwriting color may also be changed by sliding the two fingers.

Referring to fig. 9, in an embodiment, the writing control method further includes the following steps:

in step S901, a modification instruction generated by the touchpad 10 in response to the second specific operation received by the writing area is obtained.

In this embodiment, the modification instruction includes a shading modification instruction or a coloring modification instruction. In other embodiments, the modification instruction may further include smearing or erasing the generated handwriting, and the like.

And S902, modifying the generated handwriting according to the modification instruction.

In one embodiment, the touchpad 10 includes a touch sensor 11 and a touch controller 12. The touch sensor 11 is used for sensing the contact between the stylus pen 200 and the finger of the user and the touch pad 10 to generate a corresponding touch sensing signal. The touch controller 12 generates first touch coordinate data according to the received touch sensing signal. The modification instruction generated by the touchpad 10 in response to the second specific operation received by the writing area comprises: determining whether the contact area of the touch point is larger than a preset value according to the first touch coordinate data; and when the contact area is larger than the preset value, determining that the current input is through the finger of the user, and generating the modification instruction according to the first touch coordinate data. When the contact area is not larger than the preset value, it is determined that the input is currently performed through the stylus pen 200, and the first touch coordinate data is not processed, that is, the generated first touch coordinate data is directly sent to the processor 20, so that the processor 20 generates writing handwriting according to the first coordinate data.

Referring to fig. 10 again, in another embodiment, the step S902 further includes the following steps:

and step S9021, receiving a switching signal generated by the switch in response to the trigger.

The switch 40 may be a physical switch, such as a key switch or a toggle switch disposed on a side of the casing of the tablet 100. In other embodiments, the switch 40 may also be a virtual switch, for example, by forming a touch icon and displaying it on the touch panel 10, and by sending different switch signals to the processor 20 in response to a touch.

And step S9022, when the received switch signal is determined to be the first switch signal, modifying the generated handwriting according to the modification instruction.

In this embodiment, the first switching signal is a high-level signal, but it is understood that in other embodiments, the first switching signal may also be a low-level signal.

In the present embodiment, it is possible to avoid the occurrence of erroneous correction due to touching of a finger or a palm.

Referring again to fig. 11, in one embodiment, the writing control method further includes the steps of:
