Description

Technical Field

[0001] This invention relates to the field of writing interaction technology, and in particular to a writing interaction method and device based on a physical writing medium. Background Technology

[0002] In scenarios such as handwriting instruction and cultural tourism interaction, existing handwriting interaction methods mostly employ image recognition technology and complex handwriting analysis algorithms to verify stroke order, relying on LCD screens as the core interaction medium. The former requires high-performance microprocessors to support complex calculations, resulting in high system costs and power consumption, as well as high response latency, difficulty in meeting real-time interaction needs, and susceptibility to fluctuations in verification accuracy due to factors such as ambient light and writing tools. While the latter offers intuitive interaction, prolonged use of LCD screens can cause visual fatigue, especially in children, which is detrimental to eye health. Therefore, existing handwriting interaction methods are insufficient to meet the demands of low-cost, low-power, and eye-friendly teaching and interaction scenarios. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a writing interaction method and a writing interaction device based on a physical writing medium.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a writing interaction method based on a physical writing carrier, wherein the physical writing carrier includes multiple detection elements with corresponding target character spacing, and the writing interaction method based on the physical writing carrier includes the following steps: acquiring a trigger signal sequence and performing sequential verification between the trigger signal sequence and a preset target signal sequence, wherein the trigger signal sequence includes trigger signals generated sequentially by multiple detection elements; if the sequential verification results match, outputting verification qualified result information; if the sequential verification results do not match, interrupting the current verification process and outputting verification unqualified result information.

[0005] Preferably, the physical writing carrier includes at least one stroke corresponding to the target character, and a plurality of detection elements are spaced apart on the stroke. The target signal sequence includes a target signal sub-sequence corresponding to the stroke. The step of acquiring the trigger signal sequence and performing sequential verification between the trigger signal sequence and the preset target signal sequence includes the following steps: acquiring the trigger signal sub-sequence of the current stroke and performing sequential verification with the target signal sub-sequence corresponding to the current stroke; if the sequential verification result matches, outputting feedback information corresponding to the current stroke and determining whether the current stroke corresponds to the last stroke of the target character; if not, adjusting the comparison position to the next stroke corresponding to the target character, updating the target signal sub-sequence, and returning to the step of acquiring the trigger signal sub-sequence of the current stroke and performing sequential verification with the target signal sub-sequence of the current stroke; if yes, performing subsequent steps.

[0006] Preferably, before acquiring the trigger signal sequence and performing sequential verification between the trigger signal sequence and the preset target signal sequence, the method further includes the following steps: loading the preset target signal sequence and setting the first corresponding signal of the target signal sequence as the starting comparison position; after interrupting the current verification process and outputting the verification failure result information if the sequential verification result does not match, the method further includes the following steps: performing a reset operation to restore the starting comparison position.

[0007] Preferably, the detection element is a switch-type detection element, and the triggering method of the detection element includes at least one of physical contact triggering and non-contact proximity triggering.

[0008] Preferably, the switch-type detection element includes at least one of a Hall switch, a mechanical contact switch, and a photoelectric switch.

[0009] To solve the above-mentioned technical problems, the present invention provides another technical solution as follows: a writing interaction device, comprising: a physical writing carrier, the physical writing carrier including a plurality of detection elements spaced apart corresponding to target characters, the detection elements being used to generate trigger signals; a control unit, the control unit having a preset target signal sequence generated based on the correct stroke order of the target characters, the control unit being electrically connected to the detection elements, the control unit being used to acquire the trigger signal sequence and perform sequential verification between the trigger signal sequence and the preset target signal sequence; and an output unit, the output unit being electrically connected to the control unit, being used to output verification pass result information or verification fail result information.

[0010] Preferably, the writing interaction device further includes a feedback unit, which is electrically connected to the control unit. The physical writing carrier includes at least one stroke portion corresponding to the target character, and a plurality of detection elements are spaced apart on the stroke portion. The feedback unit is used to output feedback information corresponding to the stroke portion.

[0011] Preferably, the feedback unit includes an indicator light corresponding to the stroke portion. When the sequence verification result corresponding to the stroke portion matches, the control unit controls the indicator light corresponding to the stroke portion to light up.

[0012] Preferably, the writing interaction device further includes a base, a receiving component, and an electric support rod. The receiving component has a receiving space, and the physical writing medium is housed in the receiving space. The electric support rod can extend and retract to connect the physical writing medium and the base. When the verification result information is output, the control unit controls the electric support rod to drive the physical writing medium to move from the receiving space toward the base.

[0013] Preferably, the electric strut includes an outer rod, an inner rod, and a drive assembly. The outer rod is disposed on the base and has a sliding hole. The inner rod is at least partially disposed in the sliding hole and is slidably connected to the outer rod. The drive assembly is drively connected to the inner rod. When the verification result information is output, the drive assembly drives the inner rod to move towards the base.

[0014] Compared with the prior art, the writing interaction method and writing interaction device based on a physical writing carrier provided by the present invention have the following beneficial effects: 1. This invention provides a writing interaction method based on a physical writing carrier. The physical writing carrier includes multiple detection elements spaced apart to correspond to target characters. The writing interaction method based on the physical writing carrier includes the following steps: acquiring a trigger signal sequence and performing sequential verification between the trigger signal sequence and a preset target signal sequence, wherein the trigger signal sequence includes trigger signals generated sequentially by multiple detection elements; if the sequential verification results match, outputting a verification pass result; if the sequential verification results do not match, interrupting the current verification process and outputting a verification fail result. The above writing interaction method targets target characters by using multiple detection elements spaced apart to represent the target characters. The multiple spaced detection elements on the physical writing carrier acquire the trigger signal sequence and perform sequential verification with the preset target signal sequence. This eliminates the need for image recognition, complex handwriting analysis algorithms, or LCD screen interaction, thus simplifying the verification logic. Therefore, it also eliminates the need for a high-performance microprocessor, significantly reducing system cost and power consumption. At the same time, it avoids the visual fatigue caused by LCD screens and achieves eye protection; the interval-set detection elements respond quickly by directly generating trigger signals after detecting user operation, which can meet the needs of real-time interaction and is not affected by factors such as ambient light and writing tools, effectively improving the accuracy of verification and effectively adapting to teaching and interactive scenarios with high requirements for low cost, low power consumption and eye protection.

[0015] 2. In this embodiment of the invention, the physical writing carrier is divided into at least one stroke portion corresponding to the target character. Multiple detection elements are spaced apart along the stroke portion. By comparing the trigger signal subsequence of each stroke portion with the target signal subsequence, providing feedback, and updating the comparison position, stroke order verification becomes more targeted. Users can know in real time whether each stroke is written correctly, which not only improves the interactive experience and learning and memory effect, but also helps users accurately locate incorrect strokes, especially suitable for beginner stroke order teaching scenarios. The logic of stroke-by-stroke verification further simplifies the signal processing flow, reduces response latency, and avoids repeated writing due to the failure of whole-character verification, thus improving the efficiency and practicality of writing interaction.

[0016] 3. In this embodiment of the invention, by loading the target signal sequence and setting the starting comparison position before verification, a clear benchmark and execution starting point are established for subsequent sequential verification, avoiding confusion in the comparison logic and ensuring the orderliness and accuracy of the verification. After verification failure, a reset operation is performed to restore the starting comparison position, eliminating the need for the user to manually restart the system, simplifying the operation process and improving ease of use. This avoids verification errors caused by the lack of a clear comparison starting point during initial verification. Furthermore, the automatic reset step reduces interaction interruption time, adapting to the needs of frequent interactions in teaching and cultural tourism scenarios, while further reducing the complexity of system operation, matching the user's needs for low cost and ease of use.

[0017] 4. In this embodiment of the invention, the detection element is defined as a switch-type detection element, and physical contact triggering or non-contact proximity triggering is adopted. The switch-type detection element has a simple structure, low cost, and fast response speed, which can further reduce the overall system cost and power consumption, meeting the low-cost requirement. Diverse triggering methods adapt to different writing tools and usage scenarios. Whether it is contact triggering by a physical writing pen or non-contact triggering by magnetic components, signals can be stably acquired, improving the versatility and adaptability of the writing interaction method. At the same time, the switch-type detection element has strong anti-interference ability, which can reduce the impact of environmental factors on signal acquisition, ensure verification accuracy, and avoid the defects of existing image recognition technologies that are susceptible to interference.

[0018] 5. In this embodiment of the invention, the switch-type detection element includes at least one of Hall switches, mechanical contact switches, and photoelectric switches. These elements are all mature and low-cost general-purpose devices, which can further control system costs. Different types of detection elements can be adapted to different application scenarios. For example, Hall switches are adapted to non-contact writing with magnetic suction, mechanical contact switches are adapted to contact writing with traditional writing instruments, and photoelectric switches are adapted to contactless precise triggering, improving the flexibility of the method in adapting to different scenarios. In addition, the above-mentioned switch-type detection elements have the advantages of low power consumption and fast response, which can ensure the low-power operation and real-time interaction requirements of the system. At the same time, they are structurally stable, have a low failure rate, extend the service life of the system, and solve the problems of high cost and poor adaptability of existing complex detection elements.

[0019] 6. This invention provides a writing interaction device, comprising a physical writing carrier, a control unit, and an output unit. The physical writing carrier includes multiple detection elements spaced at intervals corresponding to target characters, which generate trigger signals. The control unit has a preset target signal sequence generated based on the correct stroke order of the target characters. The control unit is electrically connected to the detection elements and is used to acquire the trigger signal sequence and perform sequential verification between the trigger signal sequence and the preset target signal sequence. The output unit is electrically connected to the control unit and is used to output verification pass / fail result information. This writing interaction device, by setting up a physical writing carrier, a control unit, and an output unit, can achieve the same beneficial effects as the aforementioned writing interaction method based on a physical writing carrier. The control unit has a preset target signal sequence and is directly electrically connected to the detection elements, eliminating the need for complex algorithms and high-performance processors, significantly reducing device cost and power consumption. The physical writing carrier provides a real writing interaction carrier, avoiding visual fatigue caused by LCD screens and achieving eye protection. Simultaneously, the direct triggering signal method of the detection elements provides a rapid response, meeting real-time interaction requirements. This writing interaction device is particularly suitable for low-cost, low-power, and eye-protection-oriented teaching and interactive scenarios.

[0020] 7. In this embodiment of the invention, a feedback unit electrically connected to the control unit is provided. This feedback unit can output feedback information corresponding to each stroke, allowing the user to obtain the verification result of each stroke in real time during the writing process, without waiting for the entire character to be written, thus improving the immediacy and relevance of the interaction. The feedback unit effectively enhances the interactivity between the user and the writing interaction device, helping the user quickly correct incorrect stroke order, especially suitable for beginner stroke order teaching scenarios, improving learning effectiveness. Simultaneously, the feedback unit does not require the complex display of an LCD screen like traditional devices, maintaining eye protection. Furthermore, the feedback unit has a simple structure and low cost, without increasing the overall power consumption and cost of the writing interaction device, further optimizing the practicality and adaptability of the writing interaction device.

[0021] 8. In this embodiment of the invention, the feedback unit includes indicator lights corresponding to the strokes. When verifying and matching, the corresponding indicator light illuminates, providing intuitive and clear visual feedback. Users can quickly associate the indicator light with specific strokes to confirm the correctness of their writing. The indicator lights emit light gently, without the strong glare of an LCD screen, maximizing eye protection and meeting eye care requirements. Furthermore, the indicator light structure is simple and consumes very little power, without increasing the power consumption of the writing interaction device. The stroke-by-stroke illumination design also enhances the fun and ritual of writing, increasing user engagement, especially among children, and adapting to the needs of teaching and cultural tourism interactive scenarios. This solves the problems of existing feedback methods being insufficiently intuitive and having poor eye protection effects.

[0022] 9. In this embodiment of the invention, the structural design of the base, the receiving component, and the electric support rod realizes the storage function of the physical writing medium. When not in use, it can be stored in the receiving space, saving storage space and improving the portability and neatness of the writing interaction device. After the verification is qualified, the control unit controls the electric support rod to move the physical writing medium towards the base. The physical writing medium is recessed relative to the receiving component, thus intuitively presenting the writing verification result. Linking the writing verification result with mechanical movement further enhances the fun and sense of ritual of the interaction, especially suitable for cultural and tourism interaction scenarios, effectively improving the user experience. The linkage design of the electric support rod does not require additional manual operation. The structure is relatively simple and highly automated, maintaining the low cost and low power consumption advantages of the writing interaction device, and solving the problem of the single interaction form of existing writing interaction devices.

[0023] 10. In this embodiment of the invention, the electric support rod includes an outer rod, an inner rod, and a drive assembly. The outer rod is connected to the base, and the inner rod is slidably disposed within the sliding hole of the outer rod. The drive assembly is connected to the inner rod for transmission, thereby ensuring precise and stable extension and retraction of the electric support rod, guaranteeing the consistency and reliability of the movement of the physical writing medium. Through the sliding connection structure of the outer and inner rods and the transmission design of the drive assembly, the extension and retraction of the electric support rod is made more stable and reliable. The outer rod provides guiding support, and the inner rod slides smoothly within the sliding hole, preventing deviation or jamming during the movement of the physical writing medium. The drive assembly drives the inner rod, ensuring efficient power transmission and guaranteeing that the physical writing medium can move accurately and smoothly from the storage state to the usage position, improving the stability of the writing interaction device's movement.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0033] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0034] In this invention, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing the invention and its embodiments, and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to be constructed and operated in a specific orientation.

[0035] Furthermore, in addition to indicating direction or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in certain situations to indicate a dependency or connection. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0036] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0037] It should be noted that the target text refers to the specific characters presented on the physical writing medium. The target signal sequence refers to the correct order in which the various detection elements spaced apart on the physical writing medium should be triggered according to the correct stroke order of the target text.

[0038] Please see Figure 1 The first embodiment of the present invention provides a writing interaction method based on a physical writing carrier. The physical writing carrier includes multiple detection elements with corresponding target text spacing. The writing interaction method based on the physical writing carrier includes the following steps: Step S1: Obtain the trigger signal sequence and perform sequential verification between the trigger signal sequence and the preset target signal sequence, wherein the trigger signal sequence includes trigger signals generated sequentially by multiple detection elements; Step S2a: If the sequence verification results match, output the verification success result information; In step S2b, if the sequential verification results do not match, interrupt the current verification process and output the verification failure result information.

[0039] Understandably, the aforementioned writing interaction method based on a physical writing medium targets the target text by using multiple detection elements spaced at intervals to represent it. These spaced detection elements on the physical writing medium acquire trigger signal sequences and perform sequential verification with a preset target signal sequence. This eliminates the need for image recognition, complex handwriting analysis algorithms, or LCD screen interaction, simplifying the verification logic and thus eliminating the need for a high-performance microprocessor, significantly reducing system cost and power consumption. It also avoids the visual fatigue issues associated with LCD screens, achieving eye protection. The spaced detection elements' direct generation of trigger signals upon detecting user interaction provides a rapid response, meeting real-time interaction requirements and is unaffected by ambient light or writing tools, effectively improving verification accuracy and making it suitable for low-cost, low-power, and eye-friendly teaching and interactive scenarios.

[0040] Optionally, for the target text, multiple detection elements can be set at uniform intervals with the same spacing, or at non-uniform intervals with different spacings. Both of these arrangements can avoid a large number of detection elements continuously covering the entire stroke trajectory by setting the intervals, thereby reducing the number of detection elements used. Detection elements can exist only at key nodes of the target text strokes, thus reducing costs while ensuring the accuracy of stroke order verification.

[0041] Please see Figure 2 Furthermore, the physical writing carrier includes at least one stroke corresponding to the target character, multiple detection elements are spaced apart on the stroke, and the target signal sequence includes a target signal subsequence corresponding to the stroke. Step S1 includes the following steps: Step S11: Obtain the trigger signal subsequence of the current stroke and perform order verification with the target signal subsequence corresponding to the current stroke; Step S12: If the sequence verification result matches, output the feedback information corresponding to the current stroke part, and determine whether the current stroke part corresponds to the last stroke of the target character. If not, in step S13a, adjust the comparison position to the next stroke of the target character, update the target signal subsequence, return to obtain the trigger signal subsequence of the current stroke, and perform order verification with the target signal subsequence of the current stroke. If so, proceed with the following steps in step S13b.

[0042] Understandably, a stroke portion refers to the part of a physical writing surface corresponding to the strokes of the target character. By dividing the physical writing surface into at least one stroke portion corresponding to the target character, multiple detection elements are spaced along the stroke portion. By comparing the trigger signal subsequence of each stroke portion with the target signal subsequence, providing feedback, and updating the comparison position, stroke order verification becomes more targeted. Users can know in real time whether each stroke is written correctly, which not only improves the interactive experience and learning and memory effect, but also helps users accurately locate incorrect strokes, especially suitable for beginner stroke order teaching scenarios. The logic of stroke-by-stroke verification further simplifies the signal processing flow, reduces response latency, and avoids repeated writing due to the failure of whole-character verification, improving the efficiency and practicality of writing interaction.

[0043] Optionally, as a specific implementation manner, the spacing between multiple detection elements arranged horizontally on the stroke part is different from the spacing between multiple detection elements arranged vertically on the stroke part; or, the spacing between multiple detection elements on the stroke part is the same. By setting the spacing between multiple detection elements arranged horizontally and vertically on the stroke part to be different or the same, the adaptability and flexibility of the physical writing carrier are enhanced. When the spacing between multiple detection elements arranged horizontally and vertically on the stroke part is different, the spacing between multiple detection elements in the horizontal and vertical directions can be adjusted according to the writing rhythm of different strokes and the compactness between strokes. A larger spacing is suitable for strokes that extend longer and have a slow writing rhythm in the horizontal or vertical direction, thereby reducing redundant triggers. A smaller spacing is suitable for relatively compact and faster-written strokes in the horizontal or vertical direction, which can improve detection sensitivity. When the spacing between multiple detection elements arranged horizontally and vertically on the stroke part is the same, it is beneficial for standardized production to reduce processing costs, and different solutions can be flexibly adjusted according to specific scenarios such as the type of target text.

[0044] It should be noted that for the convenience of understanding, as a specific implementation manner, an example in this embodiment is as follows: Please refer to Figure 3 , taking the target character "中" as an example, for the entire stroke trajectory of the target character "中", a total of eleven detection elements 11 are arranged at intervals on the physical writing carrier 10, namely: the first detection element 1101, the second detection element 1102, the third detection element 1103, the fourth detection element 1104, the fifth detection element 1105, the sixth detection element 1106, the seventh detection element 1107, the eighth detection element 1108, the ninth detection element 1109, the tenth detection element 1110, and the eleventh detection element 1111. The stroke part of the first stroke "丨" of the target character "中" corresponds to the first detection element 1101, the second detection element 1102, and the third detection element 1103; the second stroke " The stroke parts of the first stroke "|" of the target character "中" correspond to the first detection element 1101, the second detection element 1102, and the third detection element 1103. When the trigger signal subsequence of the stroke part of the first stroke "|" is the same as the target signal subsequence corresponding to the current stroke part and the sequential verification result matches, the feedback information corresponding to the stroke part of the first stroke "|" is output, and it is determined that the stroke part of the first stroke "|" does not correspond to the last stroke of the target character "中", and the comparison position is adjusted to the stroke part of the second stroke of the target character "中" ", and the target signal subsequence is updated to the target signal subsequence corresponding to the stroke part of the second stroke " ". Step S11 is repeatedly executed until all stroke parts of the target character "中" are compared.

[0045] It should be noted that the specific settings of the above target characters and detection elements are only for illustrative purposes, and the number and arrangement of other target characters and detection elements are not limited here.

[0046] Furthermore, before step S1, the following steps are also included: Step S0, load a preset target signal sequence, and set the first corresponding signal of the target signal sequence as the starting comparison position.

[0047] It can be understood that by loading the target signal sequence and setting the starting comparison position before verification, a clear benchmark and execution starting point are established for subsequent sequential verification, avoiding confusion in the comparison logic, and ensuring the orderliness and accuracy of the verification.

[0048] Furthermore, after step S3, the following steps are also included: Step S3a, perform a reset operation to restore the starting comparison position.

[0049] Understandably, resetting the system after a verification failure restores the initial comparison position, eliminating the need for users to manually restart the system. This simplifies the process and improves ease of use. It avoids verification errors caused by the lack of a clear comparison starting point during initial code verification. Furthermore, the automatic reset process reduces interaction interruption time, adapting to the frequent interaction needs in teaching and cultural tourism scenarios, while further reducing system operational complexity, matching the user's requirements for low cost and ease of use.

[0050] Please see Figure 3 Furthermore, the detection element 11 is a switch-type detection element, and the triggering method of the detection element 11 includes at least one of physical contact triggering and non-contact proximity triggering.

[0051] Understandably, by defining the detection element 11 as a switch-type detection element and employing physical contact triggering or non-contact proximity triggering, the switch-type detection element boasts a simple structure, low cost, and fast response speed, further reducing the overall system cost and power consumption, thus meeting the low-cost requirement. Diverse triggering methods adapt to different writing tools and usage scenarios. Whether it's contact triggering with a physical writing pen or non-contact triggering with magnetic attachments, signals can be stably acquired, improving the versatility and adaptability of the writing interaction method. Simultaneously, the switch-type detection element has strong anti-interference capabilities, reducing the impact of environmental factors on signal acquisition, ensuring verification accuracy, and avoiding the susceptibility to interference inherent in existing image recognition technologies.

[0052] Furthermore, the switch-type detection element includes at least one of Hall switches, mechanical contact switches, and photoelectric switches.

[0053] Understandably, by incorporating switch-type detection elements, including at least one of Hall switches, mechanical contact switches, and photoelectric switches—all mature and low-cost general-purpose devices—system costs can be further controlled. Different types of detection elements can be adapted to different application scenarios. For example, Hall switches are adapted to non-contact writing with magnetic attachments, mechanical contact switches are adapted to contact writing with traditional writing instruments, and photoelectric switches are adapted to contactless precision triggering, thus improving the flexibility of the method in adapting to different scenarios. Furthermore, the aforementioned types of switch-type detection elements have the advantages of low power consumption and fast response, ensuring low-power operation and real-time interaction requirements of the system. They also exhibit structural stability, low failure rate, and extended system lifespan, solving the problems of high cost and poor adaptability of existing complex detection elements.

[0054] Optionally, as one specific implementation, the switch-type detection element adopts a Hall switch, and the operating part used by the user for writing is provided with a magnetic element. The Hall switch generates a trigger signal based on the induction effect between the user and the magnetic element during the writing operation.

[0055] Please combine Figure 4 and Figure 5 The second embodiment of the present invention provides a writing interaction device 1, which includes: The physical writing carrier 10 includes a plurality of detection elements 11 arranged at intervals corresponding to the target characters. The detection elements 11 are used to generate trigger signals. Control unit 20, which is preset with a target signal sequence generated based on the correct stroke order of the target character, is electrically connected to detection element 11. Control unit 20 is used to acquire trigger signal sequence and perform sequential verification between trigger signal sequence and preset target signal sequence. Output unit 30 is electrically connected to control unit 20 and is used to output verification result information or verification failure result information.

[0056] Understandably, this writing interaction device 1, by setting up a physical writing carrier 10, a control unit 20, and an output unit 30, can achieve the same beneficial effects as the aforementioned writing interaction method based on a physical writing carrier. The control unit 20 has a preset target signal sequence and is directly electrically connected to the detection element 11, eliminating the need for complex algorithms and high-performance processors, thus significantly reducing device cost and power consumption. The physical writing carrier 10 provides a real writing interaction carrier, avoiding visual fatigue caused by LCD screens and achieving eye protection. At the same time, the detection element 11 responds quickly by directly triggering signals, meeting real-time interaction requirements. This writing interaction device 1 is particularly suitable for low-cost, low-power teaching and interactive scenarios with high eye protection requirements.

[0057] It should be noted that, Figure 4 This demonstrates the contracted state of the physical writing medium 10. Figure 5 The storage state of the physical writing medium 10 is shown. As an optional implementation, the different states of the physical writing medium 10 can be used to output a sequence verification result signal.

[0058] Optionally, the control unit 20 includes an MCU (Microcontroller Unit). Understandably, the control unit 20 includes an MCU, which can fully utilize the low cost, low power consumption, and high integration of the MCU. The MCU can efficiently process the sequence verification of the trigger signal sequence and the preset target signal sequence, and can meet the logical operation requirements of the sequence verification without the need for a high-performance processor, thus greatly reducing the hardware cost and power consumption of the writing interaction device 1.

[0059] Optionally, the output unit 30 may output verification pass / fail result information in the form of optical signals, sound signals, etc.

[0060] Please continue to combine Figure 4 and Figure 5Furthermore, the writing interaction device 1 also includes a feedback unit 40, which is electrically connected to the control unit 20. The physical writing carrier 10 includes at least one stroke portion 12 corresponding to the target character, and multiple detection elements 11 are spaced apart on the stroke portion 12. The feedback unit 40 is used to output feedback information corresponding to the stroke portion 12.

[0061] Understandably, stroke portion 12 refers to the part on the physical writing medium 10 corresponding to the stroke of the target character. The feedback unit 40 can output feedback information corresponding to stroke portion 12, allowing the user to obtain the verification result of each stroke in real time during the writing process, without waiting for the entire character to be written, thus improving the immediacy and pertinence of the interaction. The feedback unit 40 effectively enhances the interaction between the user and the writing interaction device 1, helping the user to quickly correct incorrect stroke order, which is especially suitable for beginner stroke order teaching scenarios and can improve learning effectiveness. At the same time, the feedback unit 40 does not need to use the complex display of an LCD screen like traditional devices to output feedback information, thus maintaining the advantage of eye protection. Moreover, the feedback unit 40 has a simple structure and low cost, and will not increase the overall power consumption and cost of the writing interaction device 1, further optimizing the practicality and adaptability of the writing interaction device 1.

[0062] Please continue to combine Figure 4 and Figure 5 Furthermore, the feedback unit 40 includes an indicator light 41 corresponding to the stroke section 12. When the sequence verification result corresponding to the stroke section 12 matches, the control unit 20 controls the indicator light 41 corresponding to the stroke section 12 to light up.

[0063] Understandably, by setting the feedback unit 40 to include indicator lights 41 corresponding to the stroke section 12, the corresponding indicator light 41 is illuminated during verification and matching, providing intuitive and clear visual feedback. Users can quickly associate the indicator light 41 with specific strokes to confirm the correctness of their writing. The indicator light 41 emits light gently, without the strong glare of an LCD screen, maximizing the protection of the user's eyesight and meeting eye protection needs. In addition, the indicator light 41 has a simple structure and extremely low power consumption, without increasing the power consumption burden of the writing interaction device 1. The design of illuminating each stroke also enhances the fun and ritual of writing, increasing user engagement, especially among children, and adapting to the needs of teaching and cultural tourism interactive scenarios, solving the problems of existing feedback methods being insufficiently intuitive and having poor eye protection effects.

[0064] Please combine Figures 4 to 6 Furthermore, the writing interaction device 1 also includes a base 50, a receiving member 60, and an electric support rod 70. The receiving member 60 has a receiving space 61, in which the physical writing carrier 10 is stored. The electric support rod 70 can extend and retract to connect the physical writing carrier 10 and the base 50. When the verification result information is output, the control unit 20 controls the electric support rod 70 to drive the physical writing carrier 10 from the receiving space 61 toward the base 50.

[0065] Understandably, the structural design of the base 50, the housing 60, and the electric support rod 70 enables the storage function of the physical writing medium 10. When not in use, it can be stored in the housing space 61, saving storage space and improving the portability and neatness of the writing interaction device 1. After the verification is successful, the control unit 20 controls the electric support rod 70 to move the physical writing medium 10 towards the base 50. The physical writing medium 10 is recessed relative to the housing 60, thus intuitively presenting the writing verification result. Linking the writing verification result with mechanical movement further enhances the fun and sense of ritual of the interaction, especially suitable for cultural and tourism interactive scenarios, effectively improving the user experience. The linkage design of the electric support rod 70 does not require additional manual operation. The structure is relatively simple and highly automated, maintaining the low cost and low power consumption advantages of the writing interaction device 1, and solving the problem of the single interaction form of the existing writing interaction device 1.

[0066] Please continue to combine Figures 4 to 6 Furthermore, the electric strut 70 includes an outer rod 71, an inner rod 72, and a drive assembly 73. The outer rod 71 is mounted on the base 50 and has a sliding hole 711. The inner rod 72 is at least partially mounted in the sliding hole 711 and is slidably connected to the outer rod 71. The drive assembly 73 is drively connected to the inner rod 72. When the verification result information is output, the drive assembly 73 drives the inner rod 72 to move towards the base 50.

[0067] Understandably, by configuring the electric support rod 70, which includes an outer rod 71, an inner rod 72, and a drive assembly 73, with the outer rod 71 connected to the base 50 and the inner rod 72 slidably disposed within the sliding hole 711 of the outer rod 71, and the drive assembly 73 drivingly connecting to the inner rod 72, the telescopic movement of the electric support rod 70 is made precise and stable, ensuring the consistency and reliability of the movement of the physical writing medium 10. Through the sliding connection structure of the outer rod 71 and the inner rod 72, and the transmission design of the drive assembly 73, the telescopic movement of the electric support rod 70 is made more stable and reliable. The outer rod 71 provides guiding support, and the inner rod 72 slides smoothly within the sliding hole 711, preventing deviation or jamming during the movement of the physical writing medium 10. The drive assembly 73 drives the inner rod 72, ensuring efficient power transmission and guaranteeing that the physical writing medium 10 can move accurately and smoothly from the storage state to the use position, thus improving the stability of the movement of the writing interaction device 1.

[0068] Compared with the prior art, the writing interaction method and writing interaction device based on a physical writing carrier provided by the present invention have the following beneficial effects: 1. This invention provides a writing interaction method based on a physical writing carrier. The physical writing carrier includes multiple detection elements spaced apart to correspond to target characters. The writing interaction method based on the physical writing carrier includes the following steps: acquiring a trigger signal sequence and performing sequential verification between the trigger signal sequence and a preset target signal sequence, wherein the trigger signal sequence includes trigger signals generated sequentially by multiple detection elements; if the sequential verification results match, outputting a verification pass result; if the sequential verification results do not match, interrupting the current verification process and outputting a verification fail result. The above writing interaction method targets target characters by using multiple detection elements spaced apart to represent the target characters. The multiple spaced detection elements on the physical writing carrier acquire the trigger signal sequence and perform sequential verification with the preset target signal sequence. This eliminates the need for image recognition, complex handwriting analysis algorithms, or LCD screen interaction, thus simplifying the verification logic. Therefore, it also eliminates the need for a high-performance microprocessor, significantly reducing system cost and power consumption. At the same time, it avoids the visual fatigue caused by LCD screens and achieves eye protection; the interval-set detection elements respond quickly by directly generating trigger signals after detecting user operation, which can meet the needs of real-time interaction and is not affected by factors such as ambient light and writing tools, effectively improving the accuracy of verification and effectively adapting to teaching and interactive scenarios with high requirements for low cost, low power consumption and eye protection.

[0069] 2. In this embodiment of the invention, the physical writing carrier is divided into at least one stroke portion corresponding to the target character. Multiple detection elements are spaced apart along the stroke portion. By comparing the trigger signal subsequence of each stroke portion with the target signal subsequence, providing feedback, and updating the comparison position, stroke order verification becomes more targeted. Users can know in real time whether each stroke is written correctly, which not only improves the interactive experience and learning and memory effect, but also helps users accurately locate incorrect strokes, especially suitable for beginner stroke order teaching scenarios. The logic of stroke-by-stroke verification further simplifies the signal processing flow, reduces response latency, and avoids repeated writing due to the failure of whole-character verification, thus improving the efficiency and practicality of writing interaction.

[0070] 3. In this embodiment of the invention, by loading the target signal sequence and setting the starting comparison position before verification, a clear benchmark and execution starting point are established for subsequent sequential verification, avoiding confusion in the comparison logic and ensuring the orderliness and accuracy of the verification. After verification failure, a reset operation is performed to restore the starting comparison position, eliminating the need for the user to manually restart the system, simplifying the operation process and improving ease of use. This avoids verification errors caused by the lack of a clear comparison starting point during initial verification. Furthermore, the automatic reset step reduces interaction interruption time, adapting to the needs of frequent interactions in teaching and cultural tourism scenarios, while further reducing the complexity of system operation, matching the user's needs for low cost and ease of use.

[0071] 4. In this embodiment of the invention, the detection element is defined as a switch-type detection element, and physical contact triggering or non-contact proximity triggering is adopted. The switch-type detection element has a simple structure, low cost, and fast response speed, which can further reduce the overall system cost and power consumption, meeting the low-cost requirement. Diverse triggering methods adapt to different writing tools and usage scenarios. Whether it is contact triggering by a physical writing pen or non-contact triggering by magnetic components, signals can be stably acquired, improving the versatility and adaptability of the writing interaction method. At the same time, the switch-type detection element has strong anti-interference ability, which can reduce the impact of environmental factors on signal acquisition, ensure verification accuracy, and avoid the defects of existing image recognition technologies that are susceptible to interference.

[0072] 5. In this embodiment of the invention, the switch-type detection element includes at least one of Hall switches, mechanical contact switches, and photoelectric switches. These elements are all mature and low-cost general-purpose devices, which can further control system costs. Different types of detection elements can be adapted to different application scenarios. For example, Hall switches are adapted to non-contact writing with magnetic suction, mechanical contact switches are adapted to contact writing with traditional writing instruments, and photoelectric switches are adapted to contactless precise triggering, improving the flexibility of the method in adapting to different scenarios. In addition, the above-mentioned switch-type detection elements have the advantages of low power consumption and fast response, which can ensure the low-power operation and real-time interaction requirements of the system. At the same time, they are structurally stable, have a low failure rate, extend the service life of the system, and solve the problems of high cost and poor adaptability of existing complex detection elements.

[0073] 6. This invention provides a writing interaction device, comprising a physical writing carrier, a control unit, and an output unit. The physical writing carrier includes multiple detection elements spaced at intervals corresponding to target characters, which generate trigger signals. The control unit has a preset target signal sequence generated based on the correct stroke order of the target characters. The control unit is electrically connected to the detection elements and is used to acquire the trigger signal sequence and perform sequential verification between the trigger signal sequence and the preset target signal sequence. The output unit is electrically connected to the control unit and is used to output verification pass / fail result information. This writing interaction device, by setting up a physical writing carrier, a control unit, and an output unit, can achieve the same beneficial effects as the aforementioned writing interaction method based on a physical writing carrier. The control unit has a preset target signal sequence and is directly electrically connected to the detection elements, eliminating the need for complex algorithms and high-performance processors, significantly reducing device cost and power consumption. The physical writing carrier provides a real writing interaction carrier, avoiding visual fatigue caused by LCD screens and achieving eye protection. Simultaneously, the direct triggering signal method of the detection elements provides a rapid response, meeting real-time interaction requirements. This writing interaction device is particularly suitable for low-cost, low-power, and eye-protection-oriented teaching and interactive scenarios.

Simultaneously, the feedback unit does not require the complex display of an LCD screen like traditional devices, maintaining eye protection. Furthermore, the feedback unit has a simple structure and low cost, without increasing the overall power consumption and cost of the writing interaction device, further optimizing the practicality and adaptability of the writing interaction device.

[0075] 8. In this embodiment of the invention, the feedback unit includes indicator lights corresponding to the strokes. When verifying and matching, the corresponding indicator light illuminates, providing intuitive and clear visual feedback. Users can quickly associate the indicator light with specific strokes to confirm the correctness of their writing. The indicator lights emit light gently, without the strong glare of an LCD screen, maximizing eye protection and meeting eye care requirements. Furthermore, the indicator light structure is simple and consumes very little power, without increasing the power consumption of the writing interaction device. The stroke-by-stroke illumination design also enhances the fun and ritual of writing, increasing user engagement, especially among children, and adapting to the needs of teaching and cultural tourism interactive scenarios. This solves the problems of existing feedback methods being insufficiently intuitive and having poor eye protection effects.

The structure is relatively simple and highly automated, maintaining the low cost and low power consumption advantages of the writing interaction device, and solving the problem of the single interaction form of existing writing interaction devices.

[0077] 10. In this embodiment of the invention, the electric support rod includes an outer rod, an inner rod, and a drive assembly. The outer rod is connected to the base, and the inner rod is slidably disposed within the sliding hole of the outer rod. The drive assembly is connected to the inner rod for transmission, thereby ensuring precise and stable extension and retraction of the electric support rod, guaranteeing the consistency and reliability of the movement of the physical writing medium.
