The stylus pen 2 is a stylus pen having ink such as ink, and when the stylus pen 2 writes on the paper 3 placed on the writing pad 1, an actual writing is formed on the paper 3 at the same time.

Referring to fig. 2, fig. 2 is a block diagram of the handwriting board 1. The tablet 1 comprises a processor 11.

The processor 11 is further configured to obtain a standard word to be written currently when the handwriting board 1 enters a writing practice mode, and determine a reference coordinate area corresponding to each stroke of the standard word in the handwriting board 1 according to the handwriting of each stroke of the standard word. Wherein, the standard words can be the words on the copybook for copying.

The processor 11 obtains the touch track position of each stroke written by the user through the handwriting pen 2 and detected by the handwriting board 1, determines the coordinate area of the written stroke, determines the target area where the coordinate area of the written stroke is inconsistent with the reference coordinate area of the corresponding stroke of the standard word, and controls to generate a prompt signal in the target area.

Therefore, in the application, each time the user finishes writing one stroke of the character, the corresponding prompt is provided to prompt the stroke difference part of the standard character, so that the user can be reminded more timely, the user can pay more attention when writing the next stroke, and the improvement of the writing level is promoted more favorably.

As shown in fig. 2, the writing pad 1 further includes a transparent touch panel 12, a light emitting module 13, and a communication unit 14. The communication unit 14 is used to establish a communication connection with the external device 200.

Please refer to fig. 3, which is a schematic side view of the handwriting board 1. The light emitting module 13 is located below the transparent touch panel 12. The paper 3 is placed on the transparent touch panel 12, and when the stylus pen 2 writes on the paper 3 placed on the transparent touch panel 12, the transparent touch panel 12 simultaneously senses a touch track of the stylus pen 2 when writing on the paper 3 placed on the writing pad 1.

In some embodiments, the processor 11 controls the generation of the prompting signal in the target area to be a light-emitting signal for controlling the light-emitting module 13 to emit light in the target area, and the light-emitting module 13 emits light in the target area and emits the light through the transparent touch panel 12 for prompting.

Specifically, the processor 11 determines a coordinate area of each stroke written by the user through the stylus pen 2 according to the touch trajectory position of each stroke detected by the transparent touch panel 12, determines a target area where the coordinate area of the written stroke is inconsistent with a reference coordinate area of a corresponding stroke of a standard word, and controls the light-emitting module 13 to emit light in the target area and emit light through the transparent touch panel 12 for prompting.

The paper 3 placed on the transparent touch panel 12 is white paper, and the light emitted by the light-emitting module 13 can also be seen by the user through the paper 3. In some embodiments, the light emitted from the light emitting module 13 may be light with strong penetrating power.

It is understood that, in some embodiments, the paper placed on the transparent touch panel 12 may also be preferably paper with a higher light transmittance, which can better transmit the light signal for prompting sent by the light emitting module.

In some embodiments, the processor 11 determines that the stylus pen 2 has performed writing of the next stroke by the action of the stylus pen 2 detected by the transparent touch panel 12 leaving the transparent touch panel 12 and contacting the transparent touch panel 12, and determines that the change of the current continuously detected touch position is the touch track of the new stroke. The processor 11 detects the first touch track written by the handwriting pen 2 on the transparent touch panel 12 to start counting, determines that the current handwriting pen writes the second touch track and determines the current handwriting pen writes the second touch track as the second stroke of the standard character, and compares the current handwriting track with the reference coordinate area of the corresponding stroke of the standard character to determine the target area where the coordinate area of the current handwriting pen does not accord with the reference coordinate area of the corresponding stroke of the standard character.

In some embodiments, the processor 11 may control the handwriting board 1 to enter the calligraphy practicing mode when receiving an instruction of entering the calligraphy practicing mode from the external device 200. For example, the external device 200 may be installed with corresponding application software (APP), the application software is started in the external device 200 to communicate with the tablet 1, and the instruction for entering the handwriting practicing mode may be generated through a corresponding menu option, so that the processor 11 controls the tablet 1 to enter the handwriting practicing mode and obtains the standard word to be currently written.

In other embodiments, as shown in fig. 1, the writing pad 1 is further provided with a corresponding function key B1, and the processor 11 can control the writing pad 1 to enter a writing practice mode according to the operation of the writing pen 2 on the function key B1 of the writing pad 1, and obtain a standard word to be written currently.

In some embodiments, the processor 11 may obtain the standard word to be written currently by receiving information of the standard word to be written sent by the external device 200. For example, after entering the practice mode, the application software of the external device 200 may pop up a plurality of words or provide a search box for the user to search for a standard word to be practiced, and provide a font option for the user to select a font to be practiced, so as to generate information of a standard word to be practiced according to the standard word selected by the user and the font of the standard word and send the information to the handwriting input device 100, where the information of the standard word to be practiced includes the standard word and the font information of the standard word.

In some embodiments, the information of the standard word to be practised and written received by the processor 11 further includes handwriting information of each stroke of the word, and the processor 11 determines a reference coordinate region corresponding to each stroke of the standard word according to the handwriting information of each stroke in the information of the standard word to be practised and written.

In other embodiments, the writing pad 1 further comprises a memory 15, and the memory 15 stores therein related data of a plurality of standard words, and the related data of each standard word comprises handwriting information of each stroke of the standard word in different fonts. After receiving the information of the standard word to be written from the external device 200, the processor 11 obtains the handwriting information of each stroke of the word under the corresponding font from the memory 15 according to the standard word to be written and the font, and determines the reference coordinate area corresponding to each stroke of the standard word according to the handwriting information of each stroke.

In some embodiments, the processor 11 determines the size and the whole area of the standard word according to the preset size and position of the word written on the tablet 1, and then determines a coordinate set formed by coordinates included in each stroke according to handwriting information of each stroke of the word, where the coordinate set corresponding to each stroke is a reference coordinate area corresponding to each stroke, so as to obtain a reference coordinate area formed by the coordinate set corresponding to each stroke. Wherein the size and position of the words written on the tablet 1 may be set by the user in advance through application software in the external device or by setting the relevant function key B1 of the tablet 1.

Please refer to fig. 4, which is a schematic diagram of the tablet 1 after entering the practice mode. In an embodiment, the processor 11 further controls the light-emitting module 13 to emit light at least a part of the position of the reference coordinate region of the first stroke of the standard word to generate a prompt, so as to prompt the user of the writing position of the first stroke and the size of the first stroke, and guide the user to write at the corresponding position with the corresponding size.

In some embodiments, the processor 11 controls the generation of the cue signal at least in part of the position of the reference coordinate region of the first stroke of the standard word. Further, the processor 11 controls the light-emitting module 13 to emit light at the boundary of the first stroke and the tail part of the first stroke of the standard word to generate a prompt. For example, as shown in fig. 4, if the word practiced by the user is "wang" and the first stroke is a horizontal word, "one", the processor 11 determines the coordinate positions of the boundary regions of the first and last cuts J1 and J2 of the first stroke of the standard word, and controls the light-emitting module 13 to emit light to indicate the boundary regions of the first and last cuts of the first stroke of the standard word.

Please refer to fig. 5, which is a schematic diagram of a tablet 1 after entering a practice mode according to another embodiment. In another embodiment, the processor 11 controls the light module 13 to emit light in the whole reference coordinate region of the first stroke of the standard word to generate a more striking prompt. For example, as shown in fig. 5, the word that the user practises is "wang" word, the first stroke is a horizontal "one", and after the processor 11 determines the reference coordinate region of the first stroke of the standard word, the processor controls the light-emitting module 13 to emit light in the whole region of "one" to make a more striking prompt.

FIG. 6 is a schematic diagram of hinting at a target area where a written stroke is inconsistent with a corresponding stroke of a standard word. In some embodiments, the target areas determined by the processor 11 to have coordinate regions of the written strokes that do not coincide with the reference coordinate regions of the corresponding strokes of the standard word include a first target area Z1 that is located outside the reference coordinate regions of the corresponding strokes of the standard word. That is, the first target region Z1 is a region where a stroke written by the user is outside the reference coordinate region of the corresponding stroke of the standard word.

The processor 11 controls the light emitting module 13 to emit light of a first color in the first target area Z1 for prompt, for example, to emit red light for prompt.

As shown in fig. 6, the target region determined by the processor 11 that the coordinate region of the written stroke does not coincide with the reference coordinate region of the corresponding stroke of the standard word further includes a second target region Z1 that does not coincide with the coordinate region of the written stroke within the reference coordinate region of the corresponding stroke of the standard word. That is, the second target region Z2 is a region where the stroke written by the user is not filled in the reference coordinate region of the stroke within the reference coordinate region of the corresponding stroke of the standard word.

The processor 11 controls the light emitting module 13 to emit light of a second color in the second target area Z2 for prompt, for example, blue light for prompt.

Thus, through the prompt, the user can quickly know which parts of the current written stroke are positioned outside the corresponding stroke of the standard character, and which parts are not filled with the corresponding stroke of the standard character.

In some embodiments, the luminous cue for the last written stroke will also remain while the cue for the next written stroke is made.

Please refer to fig. 7, which is a schematic structural diagram of the light emitting module 13, wherein the light emitting module 13 includes a plurality of L ED (light-emitting diode) lamp sets L arranged in a matrix, each L ED lamp set L forms an indication point, and each L ED lamp set L includes L ED lamps with multiple colors, as shown in fig. 7, each L ED lamp set L includes red L ED lamps 121, blue L ED lamps 122, and green L ED lamps 123, so as to form a light emitting point with three primary colors, and each L ED lamp set L corresponds to at least one coordinate position on the tablet 1.

As shown in fig. 7, the handwriting input apparatus 100 further includes a power supply 16 and a switch array 17, wherein the power supply 16 is electrically connected to each L ED lamp group L1 including a red L ED lamp 121, a blue L ED lamp 122 and a green L ED lamp 123 through the switch array 17.

The processor 11 is connected to the switch array 17, the aforementioned controlling, by the processor 11, the light module 13 to emit light in a certain area includes, when the processor 11 determines that a certain area needs to be prompted by emitting light, controlling the switch array 16 to conduct the electrical connection between the power supply 15 and L ED lamps of corresponding colors in the L ED lamp group L1 corresponding to the corresponding area, so that the corresponding area displays light of corresponding colors for prompting.

Specifically, after determining a target area where the coordinate area of the written stroke does not coincide with the reference coordinate area of the corresponding stroke of the standard word, the processor 11 determines L ED lamp group L1 corresponding to the target area, and controls the switch array 17 to turn on the power supply 16 to electrically connect with L ED lamps of corresponding colors in L ED lamp group L1 corresponding to the target area, so that the target area displays light of corresponding colors for prompting.

For example, the processor 11 controls the switch array 17 to conduct the electrical connection between the power supply 16 and the red L ED lamp 121 in the L ED lamp group L corresponding to the first target area Z1 outside the reference coordinate area of the corresponding stroke of the standard word, and controls the lighting module 2 to emit red light in the first target area Z1, so that the corresponding first target area Z1 displays red for prompting.

Obviously, since each L ED lamp group L1 is composed of L ED lamps of three primary colors, the processor 11 controls one or more L ED lamps in the corresponding L ED lamp group L1 to emit light to generate corresponding colors when the user sets other colors.

The area of each L ED light group L1 may correspond to multiple coordinates on the tablet 1, for example, the resolution of the tablet 1 is 1280 × 720 or higher, and the area distinguishable to human eyes is much larger than this area, so that the light emitted from each L ED light group L1 may cover multiple coordinates on the tablet, for example, 4 × 4 — 16 coordinates on the tablet, and still be a light emitting point for human eyes, without affecting the indication of the target area.

Fig. 8 is a schematic diagram of a partial region of the light emitting module 13 and the switch array 17, as shown in fig. 8, the switch array 17 includes a plurality of switch groups 171 arranged in an array, wherein fig. 8 illustrates connections of four L ED lamp groups L1 and four switch groups 171, and fig. 8 illustrates connections of only one L ED lamp group L1 and a corresponding switch group 171.

As shown in fig. 8, each switch group 171 includes three switches 172, and each switch is electrically connected to one of the power source 16 and one of the red L ED lamp 121, the blue L ED lamp 122, and the green L ED lamp 123 of the corresponding L ED lamp group L.

Therefore, after the processor 11 determines the target area, the processor 11 may determine the L ED lamp set L corresponding to the coordinates of the target area, further determine the corresponding switch set 171, and then control the corresponding switch 172 in the corresponding switch set 171 to turn on, so that the corresponding L ED lamp is powered on to emit light to indicate the corresponding color.

In some embodiments, the light emitting direction of the red L ED lamp 121, the blue L ED lamp 122, and the green L ED lamp 123 of each L ED lamp group L1 is to emit light toward the transparent touch panel 12.

In some embodiments, the switches 172 may be MOS transistors or BJT transistors, and the processor 11 controls the corresponding switch 172 to be turned on or off by outputting a corresponding level signal.

In other embodiments, as shown in fig. 9, which is another schematic view of the light emitting module 13, the light emitting module 13 further includes a barrier 120, the barrier 120 forms a plurality of grids G1 arranged in a matrix, each L ED lamp group L1 is accommodated in one grid G1, and the barrier 120 is made of a light shielding material, so that the light emitted from each L ED lamp group L1 cannot be emitted to the periphery, but can be emitted only in the direction of the transparent touch panel 12, thereby achieving the light focusing effect.

Therefore, in the application, if a stroke of a writing word is not consistent with the stroke of a standard word, the light emitting module 13 emits light with a specific color in the inconsistent area to prompt, so that the user can timely see the stroke difference between the stroke written by the user and the standard word, thereby giving prompt to the user more timely, allowing the user to pay more attention when writing the next stroke, and more favorably promoting the improvement of the writing level.

As shown in fig. 1, in some embodiments, the handwriting board 1 further includes a connecting shaft R1 disposed in the middle of the handwriting board 1, the handwriting board 1 specifically includes two small handwriting boards 101, and the two small handwriting boards 101 can be closed around the connecting shaft R1, so as to be convenient to carry.

Wherein, the processing 13 can be a central processing unit, a singlechip, a digital signal processor, a microcontroller and the like. The memory 15 may be a solid state memory, a memory card, or the like.

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.
