[0037] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.
[0038] This disclosure provides an input device that can interact with the touchscreen of a touch terminal to perform input functions. For example... Figure 1 As shown, the input device includes a device body 100, which includes an interaction terminal 101, an electromagnetic module 102, an inertial measurement module 103, a data processing module 104, and a wireless module 105.
[0039] The electromagnetic module 102 is used to actively emit electromagnetic signals after the input device is started (the electromagnetic signal emitted when no feedback is received from the touch terminal is regarded as the first electromagnetic signal), and in response to the touch terminal receiving the electromagnetic signal, it continues to emit electromagnetic signals (the electromagnetic signal emitted after receiving feedback from the touch terminal is regarded as the second electromagnetic signal) to realize the input function of the input device in the first input mode, which is the input mode when the distance between the interactive terminal 101 and the touch terminal does not exceed a preset distance; the inertial measurement module 103 is used to acquire the dynamic data of the device body 100 in response to the touch terminal not receiving the first electromagnetic signal; the data processing module 104 is used to obtain the displacement information of the device body 100 based on the dynamic data; the wireless module 105 is used to send the displacement information to the touch terminal to realize the input function of the input device in the second input mode, which is the input mode when the distance between the interactive terminal 101 and the touch terminal exceeds a preset distance.
[0040] Specifically, upon activating the input device, the wireless module 105 (such as a Bluetooth module) in the main body 100 establishes a connection with the wireless module of the touch terminal. After successful connection, the electromagnetic module 102 is activated, and the electromagnetic module 102 begins to transmit a second electromagnetic signal.
[0041] When the electromagnetic module 102 emits the first electromagnetic signal, if the touch terminal receives the first electromagnetic signal, it will send back a feedback signal to indicate successful signal reception. If the touch terminal can successfully receive the first electromagnetic signal, it means that the distance between the interactive terminal 101 and the touch terminal is within a preset distance, for example, the distance between the interactive terminal 101 and the touch terminal is within the range of 0-10mm. The preset distance can be determined based on the effective sensing distance of the electromagnetic signal and the actual usage scenario. After receiving the feedback signal, the electromagnetic module 102 will send a second electromagnetic signal. At this time, the touch terminal can calculate the specific position coordinates of the interactive terminal 101 on the touch screen by analyzing the intensity, phase, and other parameters of the second electromagnetic signal and using a specific positioning algorithm, thereby realizing the input function in the first input mode, such as handwriting and drawing.
[0042] When the electromagnetic module 102 emits the first electromagnetic signal, if the touch terminal fails to receive the first electromagnetic signal, it will not send a feedback signal. This means that the distance between the interactive terminal 101 of the input device and the touch terminal exceeds a preset distance, for example, the distance between the interactive terminal 101 and the touch terminal exceeds 10mm. When no feedback signal is received, the electromagnetic module 102 will stop emitting the first electromagnetic signal. Subsequently, the inertial measurement module 103 starts, monitors the dynamic data such as acceleration and angular velocity of the device body 100 in real time, and transmits the monitored data to the data processing module 104. The data processing module 104 performs filtering, integration, and other processing on these dynamic data to obtain the displacement information of the device body 100 in space. Finally, the displacement information is sent to the touch terminal through the wireless module 105. The touch terminal updates the cursor position on the touch screen in real time according to the received displacement information, realizing the input function in the second input mode, such as selection and dragging.
[0043] If the pressure value detected at the interaction terminal 101 is 0, indicating that the interaction terminal 101 is not currently in contact with any medium surface, the input device will be turned off until the pressure value generated by the interaction terminal 101 is regenerated, at which point the input device will be restarted.
[0044] The input device disclosed herein can automatically switch input modes according to the usage scenario (i.e., the distance between the interactive terminal 101 and the touch terminal), significantly improving the usability of the device and the user experience. When the distance between the interactive terminal 101 and the touch terminal does not exceed a preset distance, it is in the first input mode, and the input function is realized in the first input mode through the electromagnetic module 102. When the distance exceeds the preset distance, it automatically switches to the second input mode, and the input function is realized in the second input mode using the inertial measurement module 103, the data processing module 104, and the wireless module 105. This input device breaks the spatial limitations of traditional input devices and provides users with a more flexible and efficient interaction method.
[0045] In one possible implementation, such as Figure 2 As shown, the device body 100 also includes a pressure sensing module 107. The pressure sensing module 107 is connected to the interactive terminal 101 via an elastic component 109 such as a spring. One end of the interactive terminal 101 is located inside the device body 100 and connected to the elastic component 109 and other components, while the other end makes contact with the screen or other medium surface of the touch terminal. When the interactive terminal 101 contacts the screen or other medium surface, the elastic component 109 deforms, the pressure sensing module 107 detects the pressure change, and generates an electrical signal. After receiving the electrical signal, the data processing module 104 immediately triggers the electromagnetic module 102 to start emitting a first electromagnetic signal.
[0046] In another possible implementation, the device body 100 also includes a startup component. When the user triggers the startup component, the data processing module 104 responds to the triggering event and controls the electromagnetic module 102 to begin emitting a first electromagnetic signal.
[0047] In another possible embodiment of this disclosure, such as Figure 2 As shown, the main body 100 of the device also includes several triggering components 106. The data processing module 104 generates a control signal in response to the triggering component 106 being triggered. The wireless module 105 sends the control signal to the touch terminal to implement the target function corresponding to the triggering component 106 on the touch terminal.
[0048] In this embodiment, the device body 100 is provided with a plurality of trigger components 106, the specific number of which can be set according to the actual application scenario. When the user performs operations such as pressing or sliding on the trigger component 106, the data processing module 104 immediately generates a corresponding control signal and transmits it to the wireless module 105. The wireless module 105 then transmits the control signal to the touch terminal, thereby triggering the target function corresponding to the trigger component 106.
[0049] When the input device is in the first input mode, the target function corresponding to each trigger component 106 is configured to a function related to the first input mode, such as adjusting the pen stroke effect or undoing the previous operation. When the input device is in the second input mode, the target function corresponding to each trigger component 106 is configured to a function related to the second input mode, such as left-click and right-click functions.
[0050] For example, the main body 100 of the device is equipped with a first trigger component, a second trigger component, and a third trigger component. Initially, the distance between the interactive terminal 101 and the touch terminal is less than a preset distance, and the input device is in the first input mode. At this time, the target functions of the first, second, and third trigger components are switching brush types, adjusting brush parameters, and returning to the previous operation, respectively. Assuming the user presses the first trigger component, the data processing module 104 detects this operation and generates a control signal to switch brush types, which is transmitted to the touch terminal via the wireless module 105. Ultimately, the touch terminal switches between different brushes such as pencil and brush. If the distance between the interactive terminal 101 and the touch terminal exceeds a preset distance, the device automatically switches to the second input mode. At this time, the target functions of the first, second, and third trigger components become left-click, right-click, and scroll wheel, respectively. If the user presses the first trigger component, the data processing module 104 generates a control signal for left-click and transmits it to the touch terminal, ultimately selecting an object on the touchscreen.
[0051] In this embodiment, a trigger component 106 is provided on the main body 100 of the device. The trigger component 106 can automatically adapt to different functions according to different input modes, which greatly improves the operational flexibility and functional diversity of the input device.
[0052] In another embodiment of this disclosure, the triggering component 106 is a button or touch module.
[0053] The trigger component 106 can be configured as a physical button, a tactile switch, or other button-like device. It can also be configured as a capacitive touch module, a pressure-sensitive module, or other touch module. The specific configuration depends on the function of the trigger component 106 and the user's habits. For example, if the function requires frequent triggering (such as switching tools or undoing operations), a physical button can be used. If sliding adjustment is required (such as adjusting brush size or zooming the interface), a capacitive touch module can be used. This significantly improves the interactive adaptability and operational efficiency of the input device.
[0054] In another possible embodiment of this disclosure, such as Figure 3 As shown, the input device also includes a storage shell 200 for accommodating the device body 100. The shape of the storage shell 200 is complementary to the shape of the device body 100. Placing the device body 100 in the storage shell 200 can prevent loss or damage.
[0055] In another possible embodiment of this disclosure, such as Figure 4 As shown, the housing 200 is an elastically deformable shell, and the device body 100 can tilt in any direction when placed in the elastically deformable shell. This enables the input device to perform input functions in a third input mode, which is the input mode when the interaction terminal 101 is placed in the elastically deformable shell.
[0056] The storage shell 200 is made of elastic deformable materials such as silicone and rubber. When the main body 100 of the device is placed in the storage shell 200, the pressure sensing module 107 detects the pressure value generated by the contact between the interactive terminal 101 and the storage shell 200 in real time. When the detected pressure value is within a preset range (e.g., 1-1.5N) and lasts for more than a preset time (e.g., 5 seconds), and the distance between the interactive terminal 101 and the touch terminal exceeds a preset threshold (e.g., 10mm), the device automatically switches to the third input mode.
[0057] In the third input mode, the inertial measurement module 103 acquires the tilt state of the device body 100 within the storage shell 200. The data processing module 104 calculates displacement information based on the acquired tilt state. The tilt state includes the tilt direction and tilt angle. Specifically, the tilt direction corresponds to the displacement direction of the device body 100 (e.g., tilting to the left corresponds to a leftward cursor movement), and the tilt angle corresponds to the displacement speed of the device body 100 (e.g., a 30° tilt corresponds to a cursor movement speed of 10px / second, and a 60° tilt corresponds to a speed increase to 20px / second). By converting the tilt direction and tilt angle into displacement information, the processed displacement information is finally sent to the touch terminal via the wireless module 105, realizing the input function of the input device in the third input mode.
[0058] This embodiment places the main body 100 of the device in an elastic deformation shell and uses the tilt direction and angle of the device to realize the input function. This design does not rely on a large operating surface. The cursor control can be completed by simply holding the main body 100 of the device and tilting it. This effectively saves the space on the desktop and other surfaces. It is especially suitable for small scenes or mobile demonstration scenarios. While improving space utilization, it provides users with a more convenient and flexible interactive experience.
[0059] In another embodiment of this disclosure, the bottom end of the storage shell 200 has a suction cup structure, allowing it to adhere to the surface of a medium. The suction cup design at the bottom end of the storage shell 200 enables it to firmly adhere to surfaces such as glass, metal, and smooth wood. By pressing the storage shell 200, the air inside the suction cup is squeezed out, and atmospheric pressure generates an adhesive force, which can firmly fix the storage shell 200 to surfaces such as desktops and the back of tablets, effectively improving the stability of input operations.
[0060] In another embodiment of this disclosure, the dynamic data includes angular velocity data and acceleration data, and the inertial measurement module 103 includes a gyroscope and an accelerometer. The gyroscope is used to acquire the angular velocity data of the device body 100; the accelerometer is used to acquire the acceleration data of the device body 100.
[0061] In this embodiment, to realize the function of the input device in the second input mode, a gyroscope and an accelerometer work together to acquire dynamic data of the device body 100. The specific process is as follows: First, a three-dimensional coordinate system is established, such as... Figure 5 , Figure 6As shown, with the center point of the top view of the device body 100 as the origin of the coordinate system, the line connecting the trigger component 106 and the center of the device body 100 is set as the Y-axis, with its direction pointing from the origin to the trigger component 106. The direction perpendicular to it is defined as the X-axis. The direction from the bottom of the device body 100 to the top of the device body 100 is the Z-axis, forming a complete spatial positioning system. This coordinate system corresponds to the touch terminal screen, where the X-axis corresponds to the left-right direction of the screen, the Y-axis corresponds to the up-down or front-back direction of the screen, and the Z-axis corresponds to the depth dimension or viewing angle scaling parameter of the screen.
[0062] In actual operation, the gyroscope continuously monitors the angular velocity data of the device body 100, capturing its rotational motion in the X, Y, and Z axes. The accelerometer continuously monitors the acceleration data of the device body 100, sensing its linear motion in various directions. Based on the above data, the data processing module 104 performs integration, filtering, and other processing using a specific algorithm to calculate the displacement vector of the device body 100 in a preset coordinate system. Subsequently, the direction vector of the displacement vector is mapped to the cursor movement direction on the screen. Simultaneously, according to a preset ratio, a correspondence is established between the displacement amount of the displacement vector and the cursor displacement amount on the screen. The finally determined displacement information is sent to the touch terminal to realize interactive functions in the second input mode, such as cursor movement and page scrolling.
[0063] By using gyroscopes and accelerometers to collect angular velocity and acceleration data of the main body 100 of the device in real time, the motion state of the device in three-dimensional space can be accurately captured and converted into precise displacement information, which significantly improves the accuracy and response efficiency of the input function.
[0064] In another embodiment of this disclosure, in the first input mode, a gyroscope and an accelerometer can be used to sense the tilt angle, rotation direction, and acceleration changes of the device body 100, thereby providing richer interactive dimensions. For example, when a user is drawing or writing, the gyroscope can detect the tilt angle of the device body 100 relative to the screen and dynamically adjust the width, transparency, or texture effect of the pen strokes based on this data to simulate real pen strokes. The accelerometer can capture changes in writing pressure to achieve pressure-sensitive recognition, allowing the line thickness to transition naturally with the amount of force applied.
[0065] In the first input mode, the gyroscope and accelerometer sense the tilt angle, rotation direction, and acceleration of the device body 100, providing more realistic and nuanced input feedback for close-range operation. For example, when writing or drawing, the pen stroke effect can be dynamically adjusted according to the device's tilt angle, simulating the traditional pen-and-paper writing and drawing experience. In the second input mode, the two sensors work together to monitor the displacement information of the device body 100 in three-dimensional space, converting the device's spatial motion trajectory into remote operation commands such as cursor movement and page scrolling in real time, meeting the needs of remote control. In the third input mode, the two sensors work together to monitor and detect the rotation state of the device body 100 within the storage shell 200, similarly converting the device's rotation state into remote operation commands such as cursor movement and page scrolling in real time, meeting the needs of remote control. This greatly expands the functional dimensions and application scenarios of the input device.
[0066] In another embodiment of this disclosure, such as Figure 2 As shown, the main body 100 of the device also includes a sliding groove 108 for guiding and engaging the interactive end 101.
[0067] The sliding groove 108 fixes the interactive end 101 in a radial direction perpendicular to the device body 100 (i.e., the direction surrounding the circumference of the device body 100), ensuring that the interactive end 101 does not shift circumferentially in this direction. In the axial direction parallel to the device body 100 (i.e., from the bottom end to the top end of the device body 100), the sliding groove 108 allows the interactive end 101 to slide linearly within a small range. This design ensures the stability of the interactive end 101 in the circumferential position and also provides elastic buffering of the interactive end 101 in the axial direction through the limiting structure of the sliding groove 108 (such as the axial retraction of the pen tip after being pressed during writing), effectively improving the accuracy and realistic tactile feedback of the input operation.
[0068] In another embodiment of this disclosure, the device body 100 further includes a printed circuit board, which carries the data processing module 104, the inertial measurement module 103, the wireless module 105 and the power module 110, and connects to the front-end pressure sensing module 107, the electromagnetic module 102 and the trigger component 106, etc. Through integrated circuit design, the electrical connection and collaborative operation of each functional module are realized, making the internal structural layout of the device body 100 more reasonable.
[0069] It should be understood that the various forms of processes shown above can be used to rearrange, add, or delete steps. For example, the steps described in this disclosure can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution of this disclosure can be achieved, and this is not limited herein.
[0070] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0071] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure.
