Abstract
Description
Technical Field
[0001] This invention relates to the field of electronic pen technology, and in particular to an electronic pen and a touch interaction system. Background Technology
[0002] With the widespread adoption of touchscreen devices (such as tablets, smartphones, and interactive whiteboards), electronic pens have become important auxiliary input tools for fine writing, drawing, and other operations. However, the functions of existing electronic pens are relatively limited, mainly restricted to touch or electromagnetic induction input via the pen tip. When users need to perform non-writing operations such as interface navigation (moving the cursor, clicking icons, scrolling pages), they usually need to put down the electronic pen and use their fingers to operate the screen directly, or use separate peripherals such as a mouse or touchpad.
[0003] While some electronic pens possess interface navigation capabilities, current pens rely on built-in gyroscopes and accelerometers for this purpose. This method suffers from drift issues and difficulty in achieving precise positioning. Furthermore, it requires users to raise their arm and move the entire pen in the air to control the cursor, leading to fatigue over extended periods. Additionally, this method struggles to reliably perform actions requiring rapid, precise confirmation, such as double-clicks. Summary of the Invention

[0009] In one embodiment, the control component is further configured to: Timing begins after the image content corresponding to the image detection signal undergoes a first change; If the timing duration is within the second preset duration and the image content corresponding to the image detection signal undergoes the first change again, a third confirmation control signal is output, wherein the second preset duration is longer than the first preset duration.
[0010] In one embodiment, the control component is further configured to: When the image content corresponding to the image detection signal undergoes a second change, a fourth confirmation control signal is output, wherein the second change is that the image content corresponding to the image detection signal is converted from the first image content to the second image content and then restored to the first image content after a third preset time, wherein the third preset time is longer than the first preset time.

[0024] With the widespread adoption of touchscreen devices (such as tablets, smartphones, and interactive whiteboards), electronic pens have become important auxiliary input tools for fine writing, drawing, and other operations. However, the functions of existing electronic pens are relatively limited, mainly restricted to touch or electromagnetic induction input via the pen tip. When users need to perform non-writing operations such as interface navigation (moving the cursor, clicking icons, scrolling pages), they usually need to put down the electronic pen and use their fingers to operate the screen directly, or use separate peripherals such as a mouse or touchpad.
[0025] While some electronic pens possess interface navigation capabilities, current pens rely on built-in gyroscopes and accelerometers for this purpose. This method suffers from drift issues and difficulty in achieving precise positioning. Furthermore, it requires users to raise their arm and move the entire pen in the air to control the cursor, leading to fatigue over extended periods. Additionally, this method struggles to reliably perform actions requiring rapid, precise confirmation, such as double-clicks.
[0026] To solve the above problems, refer to Figure 1 This invention proposes an electronic pen, comprising: Electronic pen body 10; Control component 20, wherein the control component 20 is disposed inside the electronic pen body 10; A cursor pointer navigation component 30 is disposed inside the electronic pen body 10. The detection end of the cursor pointer navigation component 30 is disposed in the grip area of the electronic pen body 10, and the output end of the cursor pointer navigation component 30 is electrically connected to the control component 20. The cursor pointer navigation component 30 is used to detect image information in the grip area and output an image detection signal. A communication component 40 is disposed inside the electronic pen body 10. The communication component 40 is electrically connected to the control component 20 and is communicatively connected to an external interactive device. The control component 20 is used to receive the image detection signal, confirm the motion state of the target to be measured, and output the corresponding navigation control signal through the communication component 40.
[0027] In this embodiment, the electronic pen body 10 includes a pen tip, a pressure sensor, a rod-shaped housing, and structural components. The electronic pen body 10 has corresponding receiving cavities to accommodate electronic components of the corresponding structure. The pen tip is typically made of conductive rubber, plastic, or composite material and is used for contact with the screen. Furthermore, the pen tip and the rod-shaped housing can be detachably connected to facilitate replacement of the pen tip after wear. The pressure sensor detects the pressure applied to the pen tip by the user when writing or drawing, thereby enabling precise control over line thickness or transparency. The rod-shaped housing and structural components can be made of aluminum alloy, plastic, or composite materials.
[0028] In this embodiment, the control component 20 can be implemented using at least one controller, such as an FPGA (Field Programmable Gate Array), MCU (Microcontroller Unit), DSP (Digital Signal Processor), or SOC (System on Chip). The control component 20 is located in a corresponding area inside the electronic pen body 10 to receive corresponding sensor signals, such as pressure detection signals, and output corresponding control signals to the electronic components, causing the electronic components to perform corresponding operations.
[0029] In this embodiment, the cursor pointer navigation component 30 can be implemented using an optical pointer navigation sensor. An optical pointer navigation sensor is a miniature sensor based on optical imaging principles used to detect the movement of a finger or object on a surface. By providing a corresponding grip area on the electronic pen body 10, the user's fingers can fit against a fixed area when holding the electronic pen for writing or control. Under these conditions, by correspondingly positioning the detection end of the optical pointer navigation sensor in the grip area of the electronic pen body 10, the image information of the grip area is detected, and a corresponding image detection signal is output to confirm the user's finger movement state. Based on the confirmed finger movement state, the user's function selection execution tendency is determined. The user's finger is the target to be measured, preferably the thumb or index finger. Therefore, the detection end of the cursor pointer navigation component 30 is correspondingly positioned in the thumb grip area of the electronic pen body 10. Furthermore, a microlens is placed in the area of the grip region of the electronic pen body 10 corresponding to the detection end of the cursor pointer navigation component 30. The optical axis of the lens is perpendicular to the pen surface or at an optimized angle (e.g., 75-90 degrees) to ensure clear imaging of finger skin texture or microstructures on the pen surface. A wear-resistant, light-transmitting window covers the lens; this window is flush with or slightly convex with the pen shell and can be made of sapphire glass or high-strength composite plastic. In addition, the cursor pointer navigation component 30 may include supplementary lighting elements, such as one or more side-emitting infrared LEDs (typically with wavelengths of 850nm or 940nm) driven by the control component 20. The LED light illuminates the thumb grip region of the electronic pen body 10 at a certain angle (e.g., 30-45 degrees), forming uniform illumination and reducing surface reflection interference. The sensor chip in the cursor pointer navigation component 30 can be connected to the control component 20 via an SPI or I2C interface to detect image information in the grip region and output corresponding image detection signals. The control component 20 receives image detection signals to confirm the movement state of the user's finger at the detection end of the cursor pointer navigation component 30. Based on the movement state and the preset program algorithm, it confirms the function that the user needs to perform and outputs the corresponding navigation control signal to the communication component 40 so that the communication component 40 can output to the external interactive device.
[0030] In this embodiment, the communication component 40 can be implemented using a Bluetooth component or a 2.4G wireless communication component 40. The communication component 40 can be configured independently or integrated into the control component 20. By placing the communication component 40 inside the electronic pen body 10, and preferably in an area away from the grip area, such as the upper part of the electronic pen body 10, the shielding effect on hand grip is reduced. The communication component 40 establishes a communication connection with an external interactive device, thereby enabling communication and interaction between the electronic pen and the external interactive device. When the communication component 40 is implemented using a Bluetooth component, its communication protocol is compatible with the standard HID over GATT (HOGP), allowing the electronic pen to be plug-and-play by mainstream operating systems (Windows, macOS, Android, iOS, etc.) and recognized as a mouse device.
[0031] By employing the electronic pen of this application, the accuracy and convenience of interface navigation functions in the electronic pen can be effectively improved. The electronic pen includes an electronic pen body 10, a control component 20, a cursor pointer navigation component 30, and a communication component 40. The cursor pointer navigation component 30 is located inside the electronic pen body 10, and its detection end is positioned in the grip area of the electronic pen body 10 to detect image information in the grip area and output corresponding image detection signals. The control component 20 receives the image detection signals to confirm the motion state of the target object and outputs corresponding navigation control signals to an external interactive device via the communication component 40, causing the external interactive device to perform corresponding actions, such as single-clicking or double-clicking. By setting the cursor pointer navigation component 30, the user can adjust the movement state of their fingers placed in the grip area, thereby allowing the control component 20 to confirm the interface navigation action required by the user.
[0032] refer to Figure 2 In one embodiment of the present invention, the control component 20 is further configured to: Step S100: If, based on the image content corresponding to the image detection signal, it is determined that the moving distance of the target to be tested is within a first preset moving distance range, the moving direction of the target to be tested is confirmed based on the image detection signal; and Step S200: Based on the moving distance of the target under test, the moving direction of the target under test, and the preset moving mapping relationship, output the corresponding first confirmation control signal.
[0033] In this embodiment, the first confirmation control signal includes a cursor movement control signal. It is understood that when the electronic pen performs mouse functions, the user does not need to operate on the screen surface of the external interactive device to generate a cursor on the screen of the external interactive device. The control component 20 outputs the cursor movement control signal, i.e., the first confirmation control signal, through the communication component 40, thereby controlling the cursor to move on the screen of the external interactive device, and thus selecting the corresponding target on the screen of the external interactive device. The cursor pointer navigation component 30 can detect image information of the grip area of the electronic pen body 10 and output the corresponding image signal to the control component 20, so that the control component 20 can confirm the direction and distance of the user's finger movement in the grip area of the electronic pen body 10, i.e., the movement distance and direction of the target to be measured, by comparing the image signal at the previous moment with the image signal at the current moment. It is understood that by embedding a preset movement mapping relationship in the control component 20, the movement distance and direction of the target to be measured can be converted into the corresponding cursor movement control signal. The preset motion mapping relationship is the correspondence between the movement distance and direction of the target object corresponding to the image detection signal output by the cursor pointer navigation component 30 and the movement distance and direction of the cursor. For example, the control component 20 calculates the movement distance and direction of the user's finger in the grip area of the electronic pen using a streaming light algorithm or an acceleration curve algorithm, and outputs the corresponding cursor movement control signal through the preset motion mapping relationship, thereby causing the cursor in the external interactive device to move accordingly. For example, if the control component 20 receives an image detection signal and confirms that the image corresponding to the image detection signal has a displacement of 1-3 pixels, it outputs the corresponding cursor movement control signal through the preset motion mapping relationship, causing the cursor on the screen of the external interactive device to move accordingly. In addition, for rapid and large-scale sliding of the target object on the grip end of the electronic pen body 10, a nonlinear acceleration algorithm is applied to make the cursor on the screen of the external interactive device quickly cross the screen. In this way, the user only needs to move their finger in the grip area of the electronic pen to make the cursor of the external interactive device move, which improves both the accuracy and convenience of cursor movement.
[0034] In one embodiment of the present invention, the control component 20 is further configured to: When the image content corresponding to the image detection signal undergoes a first change, a second confirmation control signal is output, wherein the first change is that the image content corresponding to the image detection signal is converted from the first image content to the second image content and then restored to the first image content, and the duration of the change in the image content from the second image content to the first image content is within a first preset duration.
[0035] In this embodiment, the second confirmation control signal is a single-click control signal. It is understood that a mouse typically has a left button and a right button, and the left button usually has two triggering methods: single-click and double-click, each corresponding to a different function. The function of a single-click is typically to select, activate, or focus on an object, such as selecting a file, icon, text, or button; positioning the cursor in a text editing area; switching the focus of a window or control; or clicking a link on a webpage. In this embodiment, the cursor pointer navigation component 30 can continuously detect the image information of the grip area of the electronic pen body 10 and output the corresponding image detection signal. When the image detection signal corresponds to an image in the grip area of the electronic pen body 10 where there is no target to be measured (i.e., no finger is present), the corresponding image content is the first image content; when the image detection signal corresponds to an image in the grip area of the electronic pen body 10 where there is a target to be measured (i.e., a finger is present), the corresponding image content is the second image content. Specifically, when the electronic pen is in mouse mode, the cursor pointer navigation component captures images of the grip area of the electronic pen body 10 at a high speed of 3000 frames per second. When the user's finger does not touch the grip area of the electronic pen body, the image information corresponding to the image detection signal output by the cursor pointer navigation component indicates that the user's finger is not present in the grip area of the electronic pen body, meaning that the cursor pointer navigation component has not detected the target in the grip area of the electronic pen body. At this time, the first image content is that the cursor pointer navigation component has not detected the target in the grip area of the electronic pen body. When the user's finger touches the grip area of the electronic pen body, the image information corresponding to the image detection signal output by the cursor pointer navigation component indicates that the user's finger is present in the grip area of the electronic pen body, meaning that the cursor pointer navigation component has detected the target in the grip area of the electronic pen body. At this time, the first image content is that the cursor pointer navigation component has detected the target in the grip area of the electronic pen body. At this time, the control device will start timing. If the user's finger is removed from the grip area of the electronic pen body within a first preset time period, the cursor pointer navigation component will again fail to detect the target in the grip area of the electronic pen body. It is understandable that the change in image content constitutes the first change. At this time, the control device outputs a first confirmation control signal. In addition, the first preset duration can be set by the R&D personnel in actual testing, for example, 150ms, to avoid both failure to recognize the function selection corresponding to the change in image content and accidental activation.In other words, the image content corresponding to the image detection signal is converted from the first image content to the second image content and then restored to the first image content. The time it takes for the second image content to be converted back to the first image content is generated within a first preset time period. That is, the user's finger moves from the area of the grip area of the electronic pen body 10 that is not in contact with the detection end of the cursor pointer navigation component 30 to the area that is in contact with the grip area of the electronic pen body 10, and then the finger leaves the area of the grip area of the electronic pen body 10. Through this triggering method, the control component 20 can output a click control signal to the communication component 40, causing the external interactive device to perform the corresponding action. The click control signal is recognized by the external interactive device as a left-click and generates a "left mouse button pressed and immediately released" HID event.
[0036] Optionally, the first image content may correspond to the presence of a target to be tested in the grip area of the electronic pen body 10, and the second image content may correspond to the absence of a target to be tested in the grip area of the electronic pen body 10.
[0037] refer to Figure 3 In one embodiment of the present invention, the control component 20 is further configured to: Step S300: After the image content corresponding to the image detection signal undergoes a first change, start timing; Step S400: When the timing duration is within the second preset duration and the image content corresponding to the image detection signal undergoes the first change again, output a third confirmation control signal, wherein the second preset duration is longer than the first preset duration.
[0038] In this embodiment, the third confirmation control signal is a double-click control signal. As mentioned above, a mouse typically has a left button and a right button, and the left button usually has two triggering methods: single click and double click, each corresponding to a different function. A quick, consecutive double left click is used to perform a default operation, such as opening a file or folder; launching an application; selecting a word by double-clicking it in a text editor; or maximizing / restoring a window in some software. In this embodiment, the cursor pointer navigation component 30 can continuously detect the image information of the grip area of the electronic pen body 10 and output the corresponding image detection signal. When the image detection signal corresponds to an image in the grip area of the electronic pen body 10 where no target is to be measured (i.e., no finger is present), the corresponding image content is the first image content; when the image detection signal corresponds to an image in the grip area of the electronic pen body 10 where a target is to be measured (i.e., a finger is present), the corresponding image content is the second image content. When the image content corresponding to the image detection signal changes from the first image content to the second image content and then back to the first image content, and the time taken for the image content to return to the first image content is within a first preset time period, the control component 20 will execute a timing action. If, within the second preset time period, the image content corresponding to the image detection signal again changes from the first image content to the second image content and then back to the first image content, and the time taken for the image content to return to the first image content is within the first preset time period, then it can be confirmed that the user needs the electronic pen to send a double-click confirmation control signal to the external interactive device. The second preset time period can be set by the R&D personnel in actual testing, for example, 300ms. It should be noted that the second preset time period needs to be greater than the first preset time period to distinguish between left-click and left-click confirmation. In other words, the user's finger moves from the area of the grip area of the electronic pen body 10 that is not in contact with the detection end of the cursor pointer navigation component 30 to the area of the grip area of the electronic pen body 10 that is in contact with the detection end of the cursor pointer navigation component 30, and then the finger leaves the area of the grip area of the electronic pen body 10 that is in contact with the detection end of the cursor pointer navigation component 30, and the above action is performed again within 300ms. Through this triggering method, the control component 20 can output a double-click control signal to the communication component 40, and the communication component 40 can send a third confirmation control signal to the external interactive device, so that the external interactive device can perform the corresponding action.
[0039] In one embodiment of the present invention, the control component 20 is configured as follows: When the image content corresponding to the image detection signal undergoes a second change, a fourth confirmation control signal is output, wherein the second change is that the image content corresponding to the image detection signal is converted from the first image content to the second image content and then restored to the first image content after a third preset time, wherein the third preset time is longer than the first preset time.
[0040] In this embodiment, the fourth confirmation control signal is a right-click control signal. As mentioned above, a mouse typically has a left button and a right button. The right button's function is to bring up a context menu, displaying operation options related to the current object. For example, right-clicking on the desktop, file, or folder brings up options such as "Open," "Copy," "Delete," and "Properties"; right-clicking on a browser webpage brings up options such as "Refresh," "View Page Source," and "Inspect"; right-clicking in a text editing area often provides functions such as "Cut," "Copy," and "Paste." Specifically, when the image detection signal corresponds to an image within the grip area of the electronic pen body 10 where the target is not being tested (i.e., no finger is present), the corresponding image content is the first image content; when the image detection signal corresponds to an image within the grip area of the electronic pen body 10 where the target is being tested (i.e., a finger is present), the corresponding image content is the second image content. Furthermore, the third preset duration can be set by the researchers during actual testing, for example, 500ms. The third preset duration is longer than the first preset duration. This avoids both the inability to recognize the function selection corresponding to the change in image content and the risk of accidental touches leading to incorrect function selection. In other words, the image content corresponding to the image detection signal changes from the first image content to the second image content and then returns to the first image content after the third preset duration. That is, the user's finger moves from the area of the grip area of the electronic pen body 10 that is not in contact with the detection end of the cursor pointer navigation component 30 to the area of the grip area of the electronic pen body 10 that is in contact with the detection end of the cursor pointer navigation component 30, and then the finger leaves the area of the grip area of the electronic pen body 10 that is in contact with the detection end of the cursor pointer navigation component 30. It can be understood that the difference between the triggering of the right-click control signal and the single-click control signal is only that the single-click control signal needs to change from the second image content to the first image content within the first preset duration, while the right-click control signal needs to change the second image content back to the first image content after the third preset duration. In other words, the difference between the first change and the second change is the different interval duration between the change from the second image content to the first image content. Specifically, the first change requires the second image content to change to the first image content within a first preset time period, and the second change requires the second image content to change to the first image content after a third preset time period. This triggering method allows the control component 20 to output a right-click control signal to the communication component 40, which then sends the right-click control signal to an external interactive device, causing the external interactive device to perform the corresponding action.
[0041] refer to Figure 4 In one embodiment of the present invention, the control component 20 is further configured to: Step S500: If the moving distance of the target to be tested is determined to be greater than the first preset distance based on the image content corresponding to the image detection signal, the moving direction of the target to be tested is confirmed based on the image detection signal; Step S600: When the movement direction of the target to be measured is horizontal, output the corresponding fifth confirmation control signal; and Step S700: When the movement direction of the target to be measured is the vertical movement direction, output the corresponding sixth confirmation control signal.
[0042] It is understandable that a mouse has trigger buttons including the left and right buttons, as well as a scroll wheel for quick interface scrolling. Therefore, to enable the electronic pen to function like a mouse scroll wheel, a corresponding control program needs to be configured in the control component 20. This program allows the control component 20 to output a corresponding scrolling control signal based on the corresponding image detection signal. In this embodiment, the system checks whether the movement distance of the target being tested, as determined by the image detection signal, is greater than a first preset distance. This determines whether the user needs the electronic pen to output a scrolling control signal to an external interactive device to scroll the page on the external interactive device. The first preset distance can be set by the developers during actual testing, for example, 8 pixels. When the movement distance of the target being tested is detected to be greater than the first preset distance, the movement direction of the target is confirmed, and a corresponding horizontal or vertical scrolling control signal, i.e., a fifth or sixth confirmation control signal, is output.
[0043] refer to Figure 5 Optionally, the control component 20 is further configured to: Step S610: When the target to be tested moves horizontally to the left, output the seventh confirmation control signal; Step S620: When the target to be measured is moving horizontally to the right, output the eighth confirmation control signal; Step S710: When the target to be measured is moving vertically upward, output the ninth confirmation control signal; Step S720: When the target to be measured is moving vertically downwards, output the tenth confirmation control signal.
[0044] Understandably, the control component 20 can confirm the movement direction of the target by the image detection signal output by the cursor pointer navigation component 30. By confirming the movement direction of the target, it outputs a corresponding scrolling control signal to the external interactive device, causing the screen content on the external interactive device to scroll accordingly. Specifically, the seventh confirmation control signal corresponds to a horizontal left scroll wheel control signal; the eighth confirmation control signal corresponds to a horizontal right scroll wheel control signal; the ninth confirmation control signal corresponds to a vertical up scroll wheel control signal; and the tenth confirmation control signal corresponds to a vertical down scroll wheel control signal.
[0045] refer to Figure 6 In one embodiment of the present invention, the electronic pen further includes a mode switching component 50, which is disposed inside the electronic pen body 10. The trigger end of the mode switching component 50 is disposed in the trigger area of the electronic pen body 10. The mode switching component 50 is electrically connected to the control component 20. The mode switching component 50 is also used to output a mode switching signal to the control component 20 when triggered. The control component 20 is used to receive the mode switching signal and switch the current working mode according to the preset working mode sequence.
[0046] In one embodiment, the mode switching component 50 can be implemented using a physical button, a capacitive touch sensing component, a pressure-triggered component, etc. It is understood that the electronic pen's primary function is to connect with electronic devices such as tablets and digital drawing tablets to achieve writing and drawing input. Therefore, the purpose of setting the cursor pointer navigation component 30 in this embodiment is to enable the electronic pen to function as a mouse, thus giving it mouse functionality in addition to its inherent functions. To achieve the switching of electronic pen functions, a corresponding mode switching component 50 needs to be set on the electronic pen. The mode switching component 50 is located inside the electronic pen body 10, and the trigger end of the mode switching component 50 is located in the trigger area of the electronic pen body 10. It is understood that to facilitate quick and convenient switching of electronic pen functions when using the electronic pen, the trigger area of the electronic pen body 10 needs to be close to or located in the grip area. It should be noted that the trigger area of the electronic pen body 10 and the detection end of the cursor pointer navigation component 30 need to be distinguished within the area of the electronic pen body 10 to avoid accidental touches leading to incorrect function execution. For example, when the mode switching component 50 is implemented using a physical button, the trigger end of the physical button can be set on the opposite side or top of the detection end of the cursor pointer navigation component 30, and the user can switch functions by pressing. When the mode switching component 50 is implemented using a capacitive touch sensing component, the user can trigger the capacitive touch sensing component by double-clicking or making a specific slide, thereby switching functions. When the mode switching component 50 is implemented using a pressure sensor or an electromagnetic induction coil, the trigger end of the mode switching component 50 can be set at the tip of the electronic pen body 10, thereby automatically turning off the mouse function when the electronic pen is writing on an external interactive device.
[0047] refer to Figure 6 In one embodiment of the present invention, the electronic pen further includes a power supply component 60, which is disposed inside the electronic pen body 10; the output terminal of the power supply component 60 is electrically connected to the power supply terminal of the control component 20, the power supply terminal of the cursor pointer navigation component 30, and the power supply terminal of the communication component 40, respectively; the power supply component 60 is used to output a corresponding power supply voltage to the power supply terminal of the control component 20, the power supply terminal of the cursor pointer navigation component 30, and the power supply terminal of the communication component 40.
[0048] In this embodiment, the power supply component 60 can be implemented using a rechargeable lithium battery and a corresponding charging and discharging circuit, or a non-rechargeable button battery and a corresponding charging and discharging circuit. The structure of the power supply component 60 needs to correspond to the structure of the electronic pen body 10, so that the power supply component 60 can accommodate a large-capacity battery within the narrow space inside the electronic pen body 10, enabling it to power the internal electrical components of the electronic pen for a longer period of time. When the power supply component 60 is implemented using a rechargeable lithium battery, a corresponding USB-C interface or wireless charging coil can be provided to charge the lithium battery.
