Embodiments

[0010] To make the description of the present disclosure more detailed and complete, reference may be made to the accompanying drawings and the following various embodiments, where the same numbers in the drawings represent the same or similar elements. For the convenience and clarity of description, the thickness or size of each element in the drawings is represented in an exaggerated or omitted or schematic manner for the understanding and reading of those skilled in the art, and the size of each element is not its actual size, and is not intended to limit the limiting conditions for the implementation of the present disclosure, so it does not have technical substantial significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects that the present disclosure can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed in the present disclosure.

[0011] Please refer to FIG. 1, which is a schematic diagram of the stylus 11 and the touch device D in the first embodiment of the present disclosure. The stylus 11 is communicatively connected to the touch device D, and the touch device D includes a touch panel TP. In some embodiments, the touch device D may be a device with a touch panel TP such as a tablet computer, a mobile phone, a graphics tablet, or a notebook computer.

[0012] In some embodiments, the stylus 11 may be a capacitive stylus, for example, a capacitive stylus that supports the USI (Universal Stylus Initiative) or MPP (Microsoft Pen Protocol) communication protocol.

[0013] The stylus 11 can perform touch input on the touch device D to control the touch device D, such as drawing in a drawing software, writing in a note software, etc. When the user needs to switch the mode of touch input (for example: switch the writing color, change the brush stroke), the stylus 11 can switch the mode through the following operations.

[0014] First, the stylus 11 obtains a mode code. Next, the stylus 11 switches from a first mode to a second mode based on the mode code, where the mode code corresponds to the second mode. Finally, the stylus 11 sends a switching instruction to the touch device D to instruct the touch device D to set a touch input of the stylus 11 to the second mode.

[0015] For example, assume that the original operation input of the stylus 11 on the drawing software of the touch device D is a black brush (i.e., the first mode), and the mode code corresponds to a red brush (i.e., the second mode). Further, after the stylus 11 obtains the mode code, it can confirm the corresponding mode (i.e., the second mode) by comparing the mode code and switch the operation input of the stylus 11 itself to a red brush. Finally, the stylus 11 sends a switching instruction corresponding to the red brush to the touch device D, instructing the touch device D to switch to a red brush.

[0016] In some embodiments, the stylus 11 also stores a look-up table for representing the correspondence between the mode code and the mode. After the stylus 11 obtains the mode code, it can confirm the mode corresponding to the mode code by comparing the look-up table and switch the stylus 11 to the corresponding mode.

[0017] Regarding the structure of the stylus 11, please refer to FIG. 2, which is a schematic diagram of the stylus 11a in the first embodiment of the present disclosure. The stylus 11a is one of the embodiments of the stylus 11. As shown in FIG. 2, the stylus 11a includes a first communication interface 111, a processor 113, and a reader 114, wherein the processor 113 is coupled to the first communication interface 111 and the reader 114 respectively.

[0018] In some embodiments, the first communication interface 111 may be an antenna supporting a stylus communication protocol (e.g., MPP communication protocol, USI communication protocol), and is disposed at one end of the tip of the stylus 11a for communicating and connecting to the touch device D through the corresponding stylus communication protocol.

[0019] In some embodiments, the processor 113 is used to determine the mode code received by the reader 114 and transmit a switching instruction to the touch device D through the first communication interface 111. The processor 113 may include a central processing unit (CPU), a multiprocessor, a microcontroller unit (MCU), a distributed processing system, an application specific integrated circuit (ASIC), and / or a suitable computing unit.

[0020] In some embodiments, the reader 114 may be a radio frequency reader for reading the mode code.

[0021] In some embodiments, when the stylus 11a transmits a switching instruction, it will determine whether the function adjusted corresponding to the second mode corresponds to the function supported by the communication protocol corresponding to the first communication interface 111. Further, in response to the function adjusted by the second mode corresponding to the function supported by the communication protocol corresponding to the first communication interface 111, the stylus 11a transmits a first switching instruction to the touch device D through the first communication interface 111 through the corresponding communication protocol, wherein the first switching instruction corresponds to the function supported by the communication protocol.

[0022] For example, when the communication interface corresponding to the first communication interface 111 is the USI communication protocol, and the stylus 11a switches the black pen to a red pen after obtaining the mode code. Since the USI communication protocol supports the conversion of pen colors, the stylus 11a can transmit a first switching instruction to the touch device D through the C.SetColor function in the USI communication protocol to switch the pen color after determining the support status.

[0023] In some embodiments, the stylus 11 and the touch device D can be communicatively connected via a stylus communication protocol such as USI or MPP and transmit a switching instruction. However, different communication protocols support different switching functions. For example, the MPP protocol does not support the switching of the pen color. In this way, the stylus 11 also needs to transmit a switching instruction via other communication protocols to supplement the deficiencies of the stylus communication protocol.

[0024] To solve the above problems, please refer to FIG. 3, which is a schematic diagram of another stylus 11b in the first embodiment of the present disclosure. As shown in FIG. 3, the stylus 11b includes a first communication interface 111, a second communication interface 112, a processor 113, and a reader 114, wherein the processor 113 is coupled to the first communication interface 111, the second communication interface 112, and the reader 114 respectively.

[0025] In some embodiments, the first communication interface 111, the processor 113, and the reader 114 of the stylus 11b can be the same as those of the stylus 11a shown in FIG. 2.

[0026] In some embodiments, the second communication interface 112 can be a wireless communication interface such as Bluetooth, near field communication, or Wi-Fi, for communicatively connecting to the touch device D via a corresponding communication protocol.

[0027] As shown in FIG. 3, the stylus 11b can transmit a switching instruction via the first communication interface 111 and / or the second communication interface 112, wherein the stylus 11b can switch the corresponding function according to the function supported by the first communication protocol (i.e., the stylus communication protocol), and for the function not supported by the first communication protocol, transmit a switching instruction via the second communication protocol (e.g., Bluetooth) to switch the remaining functions (i.e., the functions not supported by the first communication protocol).

[0028] Specifically, in response to the function adjusted in the second mode not corresponding to the function supported by the first communication protocol, the stylus 11b can transmit a second switching instruction to the touch device D via the second communication interface 112 via the second communication protocol, wherein the second switching instruction corresponds to the function adjusted in the second mode that does not correspond to the function supported by the first communication protocol.

[0029] For example, assume that the stylus 11b communicates with the touch device D via the first communication interface 111 using the MPP communication protocol. When the stylus 11b switches from a black pen to a red pen, since the MPP communication protocol does not support the switching of pen colors, the processor 113 of the stylus 11b can choose to transmit a second switching instruction via the second communication interface 112 using Bluetooth to switch the pen color.

[0030] Regarding the operation of the processor 113 transmitting the second switching instruction via the second communication interface 112 using Bluetooth, in one example, the processor 113 can transmit the second switching instruction to the touch device D via Bluetooth using the Human Interface Devices (HID) protocol in the Universal Serial Bus (USB) standard. For example, in the digitizer category of the Human Interface Devices protocol, when the function identifier (Usage ID) of a switching instruction is set to 76, the switching instruction is used to switch the brush type. In addition, when the function identifier of a switching instruction is set to one of 78 - 7F, the custom function can be switched. In other words, when the content of the switching instruction corresponding to the function is pre-set, the stylus 11b can transmit a switching instruction to the touch device D via the Human Interface Devices protocol to switch a specific function (e.g., pen color, button function, brush type).

[0031] In another example, when the stylus 11b switches from a brush stroke to a highlighter stroke, since the MPP communication protocol supports the switching of stroke types, the processor 113 of the stylus 11b can choose to transmit a first switching instruction via the first communication interface 111 using the MPP communication protocol to switch the stroke type.

[0032] In another example, when the stylus 11b switches both the pen stroke and the pen color at the same time, such as switching from a black brush to a red highlighter, since the MPP communication protocol supports the switching of stroke types but does not support the switching of pen colors, the processor 113 of the stylus 11b can transmit different switching instructions via the first communication interface 111 and the second communication interface 112 respectively. That is to say, transmit a switching instruction via the second communication interface 112 to switch the pen color, and transmit a switching instruction via the first communication interface 111 to switch the stroke type.

[0033] In this way, the stylus 11b can select different communication interfaces to send switching commands according to the functions supported by the communication protocol, so that the stylus 11b is not restricted by the communication protocol and cannot switch specific functions. For the convenience of explanation, the above paragraph only uses the pen color and the type of brushstrokes as examples for illustration. In fact, the switching commands transmitted by the stylus 11b can also include the switching of more functions.

[0034] In some embodiments, the stylus 11 further includes an output component such as a light-emitting element, a vibrator, etc., and the stylus 11 sets the output component to an output mode corresponding to the second mode based on the mode encoding. Through the above operations, when the stylus 11 switches modes based on mode encoding, the stylus 11 can also switch the mode of the output component based on mode encoding.

[0035] For example, the stylus 11 includes a vibrator, which is used to output different forms of vibration according to different types of brushstrokes of the stylus 11 when the user writes with the stylus 11 to simulate the writing touch of different brushstrokes. Suppose the stylus 11 originally writes with a brushstroke of a Chinese brush, and the vibrator also outputs the vibration corresponding to the Chinese brushstroke. When the stylus 11 switches to the highlighter mode after receiving the mode encoding, the stylus 11 further switches the vibrator to the highlighter mode and outputs the vibration corresponding to the highlighter brushstroke.

[0036] For the convenience of explanation, the above paragraph uses the vibrator as an example. In other embodiments, the stylus 11 can also switch other types of output components through the same operation. For example, when the stylus 11 has a light-emitting element, the color of the light-emitting element can also be switched based on different modes.

[0037] In some embodiments, the user can operate the function corresponding to the custom mode encoding on the touch device D. Specifically, the stylus 11 can perform a touch input on the touch panel TP of the touch device D, where the touch input is used to cause the touch device D to generate a display output based on the touch input and a custom mode.

[0038] For example, assume that the original mode encoding corresponds to a red paintbrush. The user can change the mode encoding to correspond to a yellow paintbrush through software on the touch device D (such as a drawing software). Further, when the stylus 11 obtains the mode encoding and transmits the corresponding switching instruction to the touch device D, the touch device D can, based on the original switching instruction corresponding to the red paintbrush, change the touch input of the stylus 11 to be set as the yellow paintbrush. In this way, when the stylus 11 touches the touch panel TP, the touch device D will generate a drawing result (i.e., a display output) showing a yellow paintbrush based on the movement trajectory of the stylus 11 (i.e., the touch input) and the user-defined mode (i.e., the user-defined mode).

[0039] In this embodiment, the function corresponding to the mode encoding is actually determined by the touch device D (determined by the user's input on the touch device D). Therefore, after the stylus 11 reads the mode encoding, it can first convert the mode encoding into a switching instruction (or directly use the mode encoding as the switching instruction) and transmit it to the touch device D. The touch device D confirms the corresponding function through the switching instruction and executes the function (such as the aforementioned yellow paintbrush). In some embodiments, the touch device D can also transmit the mode information corresponding to the function to the stylus 11 to instruct the stylus 11 to switch to a specific mode and adjust its function as necessary (such as changing the emission color, vibration pattern).

[0040] In some embodiments, the stylus 11 further includes an operation interface (not shown in the figure). One of at least one function of the second mode corresponds to the operation interface, and the switching instruction is further used to instruct the touch device to set an operation input of the operation interface to the second mode.

[0041] Specifically, the stylus 11 can further include operation interfaces such as buttons and knobs. When the stylus 11 obtains the mode encoding and switches the mode, the stylus 11 can also switch the function of the operation interface.

[0042] For example, the mode encoding corresponds to the function switching of the button on the stylus 11. After the stylus 11 obtains the mode encoding, the button can be switched to have the function of switching between a paintbrush and an eraser. In other words, the original button of the stylus 11 has a preset function (for example: when the user presses the button, the vibration function can be turned on or off), but after the stylus 11 obtains the mode encoding, the function of the button is changed so that the button of the stylus 11 has other functions (for example: the user can press the button to switch the stylus 11 to the paintbrush function or the eraser function).

[0043] In another example, the pattern encoding corresponds to the function switching of the knob on the stylus 11. After the stylus 11 obtains the pattern encoding, the knob can be switched to the function of adjusting the brush thickness. In other words, the knob of the original stylus 11 has a preset function (for example: the user can rotate the knob to adjust the vibration strength), but after the stylus 11 obtains the pattern encoding, the function of the knob is changed so that the knob of the stylus 11 has other functions (for example: the user can rotate the knob to adjust the thickness of the brush of the stylus 11).

[0044] According to the above embodiments, the stylus provided by the present disclosure allows the user to quickly switch the functions of the stylus.

[0045] The present disclosure also provides a stylus mode switching system for implementing the function and mode switching of the styluses 11, 11a, and 11b in the foregoing first embodiment. Please refer to FIG. 4, which is a schematic diagram of the stylus mode switching system 1 in the second embodiment of the present disclosure. The stylus mode switching system 1 includes a stylus 11 and a switch 12, wherein the stylus 11 is communicatively connected to the switch 12, and the switch 12 is used to store the pattern encoding.

[0046] It should be noted that the stylus 11 in the stylus mode switching system 1 can be the stylus 11 in the first embodiment, or the foregoing stylus 11a or stylus 11b.

[0047] In some embodiments, the switch 12 can be a radio-frequency identification tag (RFID tag), and the pattern encoding is the unique identifier (UID) of the radio-frequency identification tag. Thereby, when the stylus 11 reads the switch 12, the stylus 11 can obtain the pattern encoding.

[0048] In some embodiments, the switch 12 can further include a near-field communication (NFC) interface and a user interface. The user can input the function to be adjusted for the stylus 11 through the user interface, and when the stylus 11 reads the switch 12, the stylus 11 can obtain the pattern encoding corresponding to the function input by the user.

[0049] Specifically, the switch 12 can be provided with a user interface for providing user input, such as buttons, knobs, display screens, touch panels, etc., and the user can adjust and confirm the functions of the stylus 11 by operating the user interface. Then, the switch 12 generates a mode code based on the functions input by the user and transmits it through the near-field communication interface.

[0050] In some embodiments, the user can also customize the functions corresponding to the mode codes stored in the switch 12 by operating the touch device D. For example, assuming that the original mode code of the switch 12 corresponds to a red pen, the user can change the mode code of the switch 12 to correspond to a yellow pen through software (e.g., drawing software) on the touch device D.

[0051] In the stylus mode switching system 1 of the present embodiment, first, the stylus 11 obtains a mode code from the switch 12. Then, based on the mode code, the stylus 11 switches from a first mode to a second mode, where the mode code corresponds to the second mode. Finally, the stylus 11 transmits a switching instruction to the touch device D to instruct the touch device D to set a touch input of the stylus 11 to the second mode.

[0052] For example, assuming that the original operation input of the stylus 11 on the drawing software of the touch device D is a black pen (i.e., the first mode), and the mode code preset and stored in the switch 12 corresponds to a red pen (i.e., the second mode). Further, after the stylus 11 reads the mode code obtained from the switch 12, it can confirm the corresponding mode (i.e., the second mode) through the mode code and switch its own operation input to a red pen. Finally, the stylus 11 transmits a switching instruction corresponding to the red pen to the touch device D, instructing the touch device D to switch to a red pen.

[0053] In this way, the user can quickly switch the functions of the stylus 11 by approaching and reading the switch 12. Further, the switch 12 can also be provided with multiple tags storing different mode codes, so that the stylus 11 can be switched to more different modes. In addition, the switch 12 can also be designed with a corresponding appearance (e.g., the red area on the switch corresponds to the mode of the red pen).

[0054] Compared with the prior art where the user needs to operate on the touch panel TP to switch the functions of the stylus 11, the stylus mode switching system 1 provided by the present disclosure allows the user to switch the functions of the stylus 11 more intuitively and quickly, saving operation time and simplifying operation steps. Moreover, the switch 12 has a simple structure and low cost, and does not increase the burden on the supplier or the user.

[0055] In some embodiments, the reader 114 can be a radio frequency reader. Thus, when the user brings the reader 114 of the stylus 11a close to the switch 12, the reader 114 can read the mode code from the switch 12.

[0056] In addition to the above steps, the stylus 11 in the second embodiment can also perform all the operations and steps of the stylus 11, 11a, and / or 11b described in the first embodiment, has the same functions, and achieves the same technical effects. Those of ordinary skill in the art to which the present invention pertains can directly understand how the second embodiment performs these operations and steps based on the above first embodiment, has the same functions, and achieves the same technical effects, so details are not described herein.

[0057] According to the above embodiments, the stylus mode switching system provided by the present disclosure allows the user to quickly switch the functions of the stylus. If combined with the appearance of the switch corresponding to its function, it can allow the user to switch functions more intuitively. In addition, the switch has a simple structure and low cost, and does not increase the additional cost burden.

[0059] The stylus mode switching method 200 is applicable to a stylus mode switching system (for example, the stylus mode switching system 1 in the second embodiment), which includes a switch (for example, the switch 12 in the second embodiment) and a stylus (for example, the stylus 11, 11a, 11b in the first embodiment). The stylus is communicatively connected to a touch device (for example, the touch device D in the first embodiment). The stylus mode switching method 200 includes steps S201 to S203. However, those of ordinary skill in the art to which the present disclosure pertains can understand that the stylus mode switching method 200 in the third embodiment of the present disclosure is not limited to being applied to the stylus mode switching system 1 in the foregoing embodiments, nor is it limited to the order of the steps in the flowchart of FIG. 5.

[0060] In step S201, the stylus obtains a mode code from the switcher. In step S202, the stylus switches from a first mode to a second mode based on the mode code, where the mode code corresponds to the second mode. In step S203, the stylus sends a switching instruction to the touch device to instruct the touch device to set a touch input of the stylus to the second mode.

[0061] In some embodiments, the stylus further includes a first communication interface for communicatively connecting to the touch device via a first communication protocol, where the first communication protocol supports at least one support function.

[0064] In some embodiments, the stylus further includes an output component, and the stylus mode switching method 200 further includes the stylus setting the output component to an output mode corresponding to the second mode based on the mode code.

[0065] In some embodiments, the stylus is further used to store a look - up table, and step S202 further includes the stylus comparing the look - up table based on the mode code to confirm an operating mode corresponding to the mode code; and in response to the operating mode corresponding to the mode code being the second mode, the stylus switches from the first mode to the second mode.

[0066] In some embodiments, the switch further includes an input interface, and step S201 further includes the switch receiving an input mode through the input interface; and the switch transmitting the mode code corresponding to the input mode to the stylus based on the input mode.

[0067] In some embodiments, the touch device further includes a touch panel, and the stylus mode switching method 200 further includes the stylus performing a touch input on the touch panel of the touch device, where the touch input is used to cause the touch device to generate a display output based on the touch input and a custom mode.

[0068] In some embodiments, step S202 further includes the stylus receiving a mode information from the touch device, where the mode information is generated by the touch device based on the switching instruction, and the switching instruction is generated by the stylus based on the mode code; and the stylus switching from the first mode to the second mode based on the mode information.

[0069] In some embodiments, the stylus further includes an operation interface, at least one of the functions of the second mode corresponds to the operation interface, and the switching instruction is further used to instruct the touch device to set an operation input of the operation interface to the second mode.

[0070] According to the above embodiments, the stylus mode switching method provided by the present disclosure allows the user to quickly switch the functions of the stylus.
