Description

Technical Field

[0001] This invention relates to the field of handwriting devices and handwriting methods, and in particular to a specific linear realization method, a stylus, a handwriting system, a computer device, and a computer-readable storage medium. Background Technology

[0002] Traditional notebooks record text on paper. However, due to the fragility and low reusability of paper, writing large amounts of text on traditional paper can be wasteful in certain applications, hindering sustainable development. To achieve recyclable writing materials, touch input is commonly used, allowing users to handwrite text on smart devices. For example, using a stylus on a tablet or computer displays a pattern that closely resembles the actual handwriting. This touch input method effectively replaces traditional paper, allows for erasing and reuse, and promotes sustainable development.

[0003] Currently, handwriting tablet technology can be mainly divided into two categories. The first type of handwriting tablet senses the position of the pen tip first through a specific structure, and then displays color at the corresponding position through its control system, thereby generating handwriting information on the writing path. This type of handwriting tablet sensing method can be divided into resistive pressure type, electromagnetic pressure type, and capacitive touch type. Resistive pressure type sensing consists of a deformable resistive film and a fixed resistive film. When pressure is applied to the surface of the handwriting tablet, the deformable film contacts the fixed film at the pressure point, thereby sensing the position of the pen or finger. Electromagnetic pressure type sensing uses the electromagnetic field generated by the internal circuit of the handwriting tablet. By sensing the interaction between the induction coil of the pen tip and the electromagnetic field, the position of the pen tip is obtained. Capacitive touch type sensing uses the capacitance of the human body to sense the position of the finger. When the finger touches the handwriting tablet, capacitance is generated on the surface of the tablet. With the assistance of a sensing matrix and a special chip, the handwriting tablet can continuously track the trajectory of the user's handwriting capacitance and accurately locate the position of the finger. After confirming the trajectory of the object being written on, this type of writing tablet can generate pattern information on the corresponding trajectory to achieve a writing experience close to that of traditional paper. However, the accuracy of the writing trajectory generated on this type of writing tablet depends on the accuracy of the sensor and the pixel density of the display on the tablet. Furthermore, the step of sensing before displaying introduces a certain delay. High-speed and high-precision handwriting generation places higher demands on the writing tablet and will result in higher costs.

[0004] The second type of handwriting tablet is represented by liquid crystal display (LCD) tablets, which integrate sensing and display, providing a writing experience closer to traditional paper. LCD tablets have a simpler structure, requiring no complex sensing and control circuits. Their sensing and display rely solely on the physical properties of bistable liquid crystals. Under normal conditions, bistable liquid crystals can maintain two states: "transparent" and "opaque." When the entire screen is in a "transparent" state, no handwriting information is displayed. When a stylus is applied to the screen, the resulting physical pressure alters the local state of the liquid crystal, thus displaying the handwriting. When a specific voltage signal is applied to the liquid crystal surface, it returns to a "transparent" state, and the handwriting is erased. LCD tablets rely on the intrinsic physical properties of liquid crystals for sensing and display, resulting in a simple structure and low power consumption. Furthermore, the handwriting on an LCD tablet is not composed of pixels but of individual liquid crystal molecules in an "opaque" state, easily achieving ultra-high resolution. Compared to the first type of handwriting tablet, LCD tablets have significant advantages in cost, power consumption, and resolution, but they also have certain drawbacks. The first type of handwriting tablet separates the sensing and display processes, relying more on program control. It can easily erase localized handwriting. In contrast, LCD handwriting tablets, which rely on the physical properties of materials, are a single unit, and can refresh the entire page through overall bias. However, compared to the first type of handwriting tablet, it is difficult to achieve localized erasure, and it is also difficult to easily create dashed lines, dotted lines, and other line shapes as easily as electronically controlled screens.

[0005] Currently, no effective solutions have been proposed for the problems existing in related technologies, such as the difficulty in achieving specific lines on LCD handwriting tablets, the high cost and high power consumption caused by relying on program control to achieve specific lines.

[0062] Example 1

[0063] This embodiment relates to a specific linear implementation method, computer device, and computer-readable storage medium of the present invention.

[0064] Figure 1 This is a flowchart (a) of a specific linear implementation method according to an embodiment of the present invention. For example... Figure 1 As shown, a specific linear implementation method includes:

[0065] Step S102: Obtain instruction information;

[0066] Step S104: In response to the instruction information, generate handwriting tablet control information and stylus control information, wherein the handwriting tablet control information is used to instruct the handwriting tablet to change the display mode, and the stylus control information is used to instruct the stylus to change the illumination mode.

[0067] Among them, the specific line shape is a non-continuous line shape, and the specific line shape includes at least dashed lines and dotted lines.

[0068] Among them, the handwriting tablet is a light-erasable handwriting tablet.

[0069] The handwriting tablet's display modes include a writing mode and a partial erase mode. The writing mode allows you to write anywhere on the tablet and create handwriting; the partial erase mode allows you to erase handwriting in a specific area while preserving handwriting in other areas.

[0070] The stylus's light-emitting modes include constant-on mode and flashing mode. Constant-on mode means that the stylus's light-emitting unit emits a single wavelength of light signal; flashing mode means that the stylus's light-emitting unit switches between emitting a single wavelength of light signal and not emitting light signal at a preset frequency, or the stylus's light-emitting unit switches between emitting a first wavelength of light signal and emitting a second wavelength of light signal at a preset frequency (the second wavelength is not equal to the first wavelength).

[0071] In this invention, a stylus is used to simultaneously control both the stylus and the writing tablet, thereby enabling the display of specific line shapes on the writing tablet. Specifically:

[0072] (1) The handwriting tablet is in partial erase mode, and the stylus is in flashing mode;

[0073] (2) The handwriting tablet switches between writing mode and partial erasure mode at a preset frequency, and the stylus is in constant light mode;

[0074] (3) The handwriting tablet switches between writing mode and partial erasure mode at a preset frequency, and the stylus is in flashing mode.

[0075] For methods (1) to (3), the stylus may or may not have a specific line shape built in.

[0076] In step S102, the instruction information is the instruction information sent by the user to the stylus. Specifically, the user can send instruction information to the stylus through mechanical operation (such as pressing a button, touching a specific area, etc.), or the user can send instruction information to the stylus through voice.

[0077] In step S102, the instruction information includes at least the information to switch to a specific linearity.

[0078] Further, in step S104, as Figure 2 As shown, the generated handwriting tablet control information includes:

[0079] Step S202: Generate first handwriting tablet control information, wherein the first handwriting tablet control information is used to instruct the handwriting tablet to switch between writing mode and partial erasure mode at a preset frequency;

[0080] Step S204: Generate second handwriting tablet control information, wherein the second handwriting tablet control information is used to indicate that the handwriting tablet is in partial erase mode.

[0081] Among them, steps S202 and S204 are parallel and mutually exclusive steps, that is, only the first handwriting tablet control information is generated or only the second handwriting tablet control information is generated.

[0082] Furthermore, generating handwriting tablet control information also includes:

[0083] Step S206: Generate third handwriting tablet control information, wherein the third handwriting tablet control information is used to indicate that the handwriting tablet is in writing mode.

[0084] Among them, steps S206, S202, and S204 are parallel and mutually exclusive steps, that is, only the first handwriting tablet control information is generated, or only the second handwriting tablet control information is generated, or only the third handwriting tablet control information is generated.

[0085] Further, in step S104, as Figure 3 As shown, the generated stylus control information includes:

[0086] Step S302: Generate first stylus control information, wherein the first stylus control information is used to indicate that the stylus's light-emitting mode is constant-on mode;

[0087] Step S304: Generate second stylus control information, wherein the second stylus control information is used to indicate that the stylus's light-emitting mode is flashing mode.

[0088] Among them, steps S302 and S304 are parallel and mutually exclusive steps, that is, only the first stylus control information is generated or only the second stylus control information is generated.

[0089] Further, in step S104, as Figure 4 As shown, the generated tablet control information and stylus control information include:

[0090] Step S402: Generate first handwriting tablet control information and first stylus control information, wherein the first handwriting tablet control information is used to instruct the handwriting tablet to switch between writing mode and partial erasure mode at a preset frequency, and the first stylus control information is used to instruct the stylus to be in constant light mode.

[0091] Step S404: Generate second handwriting tablet control information and second stylus control information, wherein the second handwriting tablet control information is used to indicate that the handwriting tablet is in partial erasure mode, and the second stylus control information is used to indicate that the stylus's light emission mode is flashing mode.

[0092] Step S406: Generate first handwriting tablet control information and second stylus control information, wherein the first handwriting tablet control information is used to instruct the handwriting tablet to switch between writing mode and partial erasure mode at a preset frequency, and the second stylus control information is used to instruct the stylus to light up in flashing mode.

[0093] Among them, steps S402, S404, and S406 are parallel and mutually exclusive steps, that is, only the first handwriting tablet control information and the first handwriting pen control information are generated, or only the second handwriting tablet control information and the second handwriting pen control information are generated, or only the first handwriting tablet control information and the second handwriting pen control information are generated.

[0094] For step S402, the process of forming a specific linear shape is as follows:

[0095] When the handwriting tablet is in writing mode, the stylus can be used to write on the tablet, forming lines (or dots);

[0096] When the handwriting tablet is in partial erase mode, the stylus cannot form lines (or dots) when writing on the handwriting tablet.

[0097] Because the writing tablet switches between writing mode and partial erasure mode at a preset frequency, the stylus can be used to write on the writing tablet to form dotted lines or dashed lines.

[0098] In step S402, the preset frequency can be:

[0099] 1) The retention time in writing mode is longer than that in partial erase mode;

[0100] 2) The retention time of writing mode is equal to the retention time of partial erase mode;

[0101] 3) The retention time of writing mode is shorter than that of partial erase mode.

[0102] The preset frequency can be any one of the three methods mentioned above, or any combination of two or three.

[0103] By setting a preset frequency, the distance between two "lines" ("line" and "dot", two "dots") can be adjusted; by changing the preset frequency, the length of the line can be adjusted, and the shape of the line can be changed (i.e., from "line" to "dot", or from "dot" to "line").

[0104] For step S404, the process of forming a specific line shape is as follows:

[0105] (a) The stylus flashing mode is on and off.

[0106] When the stylus is illuminated, writing on the writing tablet with the stylus cannot form lines (or dots);

[0107] When the stylus is not illuminated, writing on the writing tablet with the stylus can form lines (or dots);

[0108] Because the stylus switches between emitting light and not emitting light at a preset frequency, it can be used to write on the writing tablet to form dotted lines or dashed lines.

[0109] In step S404, the preset frequency can be:

[0110] 1) The time spent emitting light is longer than the time spent not emitting light;

[0111] 2) The time it emits light is equal to the time it does not emit light;

[0112] 3) The time it emits light is less than the time it does not emit light.

[0113] The preset frequency can be any one of the three methods mentioned above, or any combination of two or three.

[0114] By setting a preset frequency, the distance between two "lines" ("line" and "dot", two "dots") can be adjusted; by changing the preset frequency, the length of the line can be adjusted, and the shape of the line can be changed (i.e., from "line" to "dot", or from "dot" to "line").

[0115] (ii) The stylus flashing mode consists of emitting a first wavelength light signal and emitting a second wavelength light signal.

[0116] When the stylus emits a light signal of the first wavelength, it cannot form lines (or dots) when writing on the writing tablet.

[0117] When the stylus emits a light signal of the second wavelength, the stylus can write on the writing tablet to form lines (or dots);

[0118] Because the stylus switches between a first wavelength light signal and a second wavelength light signal according to a preset frequency, the stylus can write on the writing tablet to form dotted lines or dashed lines.

[0119] In step S404, the preset frequency can be:

[0120] 1) The duration of the first wavelength light signal is greater than the duration of the second wavelength light signal;

[0121] 2) The duration of the first wavelength light signal is equal to the duration of the second wavelength light signal;

[0122] 3) The duration of the first wavelength light signal is shorter than the duration of the second wavelength light signal.

[0123] The preset frequency can be any one of the three methods mentioned above, or any combination of two or three.

[0124] By setting a preset frequency, the distance between two "lines" ("line" and "dot", two "dots") can be adjusted; by changing the preset frequency, the length of the line can be adjusted, and the shape of the line can be changed (i.e., from "line" to "dot", or from "dot" to "line").

[0125] For step S406, the process of forming a specific linear shape is as follows:

[0126] When the handwriting tablet is in writing mode, the stylus (whether or not it is glowing) can form lines (or dots) when writing on the tablet.

[0127] When the writing tablet is in partial erase mode and the stylus is not illuminated, writing with the stylus on the writing tablet can form lines (or dots);

[0128] When the writing tablet is in partial erase mode and the stylus is illuminated, the stylus cannot form lines (or dots) when writing on the writing tablet.

[0129] Because the writing tablet switches between writing mode and partial erasure mode at a first preset frequency, and the stylus switches between light-emitting and non-light-emitting modes at a second preset frequency, the stylus can write on the writing tablet to form complex lines.

[0130] In step S406, the first preset frequency can be:

[0131] 1) The retention time in writing mode is longer than that in partial erase mode;

[0132] 2) The retention time of writing mode is equal to the retention time of partial erase mode;

[0133] 3) The retention time of writing mode is shorter than that of partial erase mode.

[0134] The first preset frequency can be any one of the three methods mentioned above, or any combination of two or three.

[0135] In step S406, the second preset frequency can be:

[0136] 1) The time spent emitting light is longer than the time spent not emitting light;

[0137] 2) The time it emits light is equal to the time it does not emit light;

[0138] 3) The time it emits light is less than the time it does not emit light.

[0139] The second preset frequency can be any one of the three methods mentioned above, or any combination of two or three.

[0140] The first preset frequency and the second preset frequency may be the same or different.

[0141] The distance between two “lines” (a “line” and a “dot”, or two “dots”) can be adjusted by using the first preset frequency and the second preset frequency; the length of the line can be adjusted by changing the first preset frequency and the second preset frequency, and the shape of the line can be changed (i.e., from a “line” to a “dot”, or from a “dot” to a “line”).

[0142] Through the above steps, specific line shapes (such as dashed lines and dotted lines) can be achieved on the light-erasing writing tablet; compared with other styluses and writing tablets, it achieves the display of specific line shapes at a lower cost and with lower power consumption.

[0143] Figure 5 This is a flowchart (V) of a specific linear implementation method according to an embodiment of the present invention. For example... Figure 5 As shown, specific linear implementation methods also include:

[0144] Step S502: Obtain movement speed information, wherein the movement speed information is the movement speed of the stylus;

[0145] Step S504: In response to the movement speed information, generate handwriting tablet adjustment information and / or stylus adjustment information, wherein the handwriting tablet adjustment information is used to indicate the switching frequency of the handwriting tablet's adjustment display mode, and the stylus adjustment information is used to indicate the light emission frequency of the stylus's adjustment light emission mode.

[0146] Steps S502 to S504 are executed after steps S102 to S104.

[0147] In step S502, the stylus moves at a constant speed.

[0148] Step S504 includes the following methods:

[0149] 1) Only handwriting tablet adjustment information is generated. In this case, the handwriting tablet control information is the first handwriting tablet control information, and the stylus control information is the first stylus control information.

[0150] 2) Only stylus adjustment information is generated. In this case, the handwriting tablet control information is the second handwriting tablet control information, and the stylus control information is the second stylus control information.

[0151] 3) Generate at least one of the handwriting tablet adjustment information and the stylus adjustment information. In this case, the handwriting tablet control information is the first handwriting tablet control information and the stylus control information is the second stylus control information. That is, it is possible to generate only the handwriting tablet adjustment information, generate only the stylus adjustment information, or generate both the handwriting tablet adjustment information and the stylus adjustment information simultaneously.

[0152] In step S504, the specific implementation method includes:

[0153] In response to movement speed information, first frequency information is generated;

[0154] Determine the relationship between the first frequency information and the preset frequency information;

[0155] If the first frequency information is equal to the preset frequency information, frequency maintenance information is generated, wherein the frequency maintenance information is used to instruct the handwriting tablet and / or stylus to maintain the existing frequency unchanged;

[0156] If the first frequency information is not equal to the preset frequency information, frequency change information is generated, wherein the frequency change information is used to indicate that the frequency of the handwriting tablet and / or stylus is adjusted to the first frequency information.

[0157] In some embodiments, when the first frequency information is not equal to the preset frequency information, the method further includes:

[0158] In response to the first frequency information and the preset frequency information, a first frequency difference information is generated;

[0159] Determine the relationship between the first frequency difference information and the preset frequency difference information;

[0160] If the first frequency difference information is not greater than the preset frequency difference information, frequency maintenance information is generated;

[0161] If the first frequency difference is greater than the preset frequency difference, frequency change information is generated.

[0162] Through steps S502 to S504, distance control of a specific line shape can be achieved, so that the distance between two adjacent shapes in the specific line shape remains consistent. For example, the distance between two adjacent dashed lines remains consistent, and the distance between adjacent dashed lines and points remains consistent.

[0163] Figure 6 This is a flowchart (VI) of a specific linear implementation method according to an embodiment of the present invention. For example... Figure 6 As shown, specific linear implementation methods also include:

[0164] Step S602: Obtain acceleration information, wherein the acceleration information is the acceleration of the stylus;

[0165] Step S604: In response to the acceleration information, generate handwriting tablet adjustment information and / or stylus adjustment information, wherein the handwriting tablet adjustment information is used to indicate the switching frequency of the handwriting tablet's adjustment display mode, and the stylus adjustment information is used to indicate the light emission frequency of the stylus's adjustment light emission mode.

[0166] Steps S602 to S604 are executed after steps S102 to S104.

[0167] In step S602, the stylus moves at variable speed. This variable speed movement can be accelerated, decelerated, or a combination of both (i.e., a period of accelerated movement followed by a period of decelerated movement).

[0168] In some embodiments, the variable speed motion can be a mixed variable speed movement of accelerated motion and uniform motion, a mixed variable speed movement of decelerated motion and uniform motion, or a mixed variable speed movement of accelerated motion, decelerated motion and uniform motion.

[0169] Step S604 includes the following methods:

[0170] 1) Only handwriting tablet adjustment information is generated. In this case, the handwriting tablet control information is the first handwriting tablet control information, and the stylus control information is the first stylus control information.

[0171] 2) Only stylus adjustment information is generated. In this case, the handwriting tablet control information is the second handwriting tablet control information, and the stylus control information is the second stylus control information.

[0172] 3) Generate at least one of the handwriting tablet adjustment information and the stylus adjustment information. In this case, the handwriting tablet control information is the first handwriting tablet control information, and the stylus control information is the second stylus control information. That is, it is possible to generate only the handwriting tablet adjustment information, generate only the stylus adjustment information, or generate both the handwriting tablet adjustment information and the stylus adjustment information at the same time.

[0173] In step S604, the specific implementation includes:

[0174] In response to acceleration information, a second frequency information is generated;

[0175] Determine the relationship between the second frequency information and the preset frequency information;

[0176] When the second frequency information is equal to the preset frequency information, frequency maintenance information is generated, wherein the frequency maintenance information is used to instruct the handwriting tablet and / or stylus to maintain the existing frequency unchanged;

[0177] If the second frequency information is not equal to the preset frequency information, frequency change information is generated, wherein the frequency change information is used to indicate that the frequency of the handwriting tablet and / or stylus is adjusted to the second frequency information.

[0178] In some embodiments, when the second frequency information is not equal to the preset frequency information, the method further includes:

[0179] In response to the second frequency information and the preset frequency information, a second frequency difference information is generated;

[0180] Determine the relationship between the second frequency difference information and the preset frequency difference information;

[0181] If the second frequency difference information is not greater than the preset frequency difference information, frequency maintenance information is generated;

[0182] If the second frequency difference information is greater than the preset frequency difference information, frequency change information is generated.

[0183] Through steps S602 to S604, distance control of a specific line shape can be achieved, so that the distance between two adjacent shapes in the specific line shape remains consistent. For example, the distance between two adjacent dashed lines remains consistent, and the distance between adjacent dashed lines and points remains consistent.

[0212] Example 3

[0213] This embodiment relates to a specific implementation of the present invention.

[0214] A specific embodiment of the present invention, such as Figure 10As shown, a stylus for achieving specific line shapes on an optically erasable writing tablet includes a control system 1A, a power supply system 1B, and a light-emitting system 1C. The control system 1A draws power from the power supply system 1B; it receives control information from the user and emits specific wireless signals to control the optically erasable writing tablet, and outputs a special voltage waveform to control the light-emitting system 1C; the light-emitting system 1C receives the special voltage waveform emitted by the control system 1A and emits light of different frequencies, thereby controlling the writing to be erased at specific intervals during the writing process to achieve specific line shapes.

[0215] The control system 1A includes an information receiving module, a control module, a wireless communication module, and an adjustable output module. Its operation is as follows: information received by the information receiving module is transmitted to the control module, which further converts it into specific signals and outputs them to the wireless communication module and the adjustable output module.

[0216] The information receiving module is preferably a mechanical button, but other wireless communication methods can also be used.

[0217] The control module can be an 8051 series microcontroller, or other commonly used microcontrollers.

[0218] The wireless communication module can be either an infrared communication module or a Bluetooth module. The wireless communication module can send wireless signals to the optical erasing tablet, controlling it to switch between writing and partial erasing states at a specific frequency.

[0219] The adjustable output module can be a traditional DAC chip or other related adjustable components. It is controlled by the control module and outputs a voltage signal of a specific waveform to control the light-emitting system IC.

[0220] In addition, the control system 1A may also include a displacement detection module.

[0221] The displacement detection module can be a commonly used acceleration sensor, which can detect the acceleration of the user when writing and then transmit the signal to the control module.

[0222] The power supply system 1B is preferably powered by a lithium battery or several button batteries, but other power-generating components are also acceptable. Preferably, the power supply system 1B can charge the stylus via a Type-C port, wireless charging module, or other charging methods.

[0223] The light-emitting system 1C can be an LED of the corresponding wavelength or other light-emitting elements of the corresponding wavelength, which can achieve flashing at a specific frequency under the control of a specific output waveform.

[0224] The usage method of this embodiment is as follows:

[0225] The user sends commands to the control system 1A through the information receiving module;

[0226] The control system 1A receives the user's instructions, draws power from the power supply system 1B, and adjusts the wireless signal and output waveform in real time according to the sensing information of the displacement detection module therein. This causes the light erasing handwriting tablet to switch between writing mode and partial erasing mode at a certain frequency, and the light-emitting system 1C to flash at a certain frequency, ultimately achieving a specific line shape during the writing process.

[0227] The technical effects of this invention are as follows:

[0228] 1) Compared to ordinary LCD writing tablets, the combination of the stylus and the light-erasable writing tablet of this invention can achieve specific line shapes;

[0229] 2) Compared with other combinations of styluses and electronic tablets, the stylus and light-erasable writing tablet of the present invention have lower costs and lower energy consumption.

Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
