Description

Technical Field

[0002] In a touch device using infrared technology, the writing operation relies on the precise occlusion of light to determine the position of the touch point. Specifically, when a user writes with a stylus, the system accurately locates the writing position by detecting the occlusion of infrared rays by the tip of the stylus. However, in practical applications, if a single user attempts to write in a natural way - that is, writing with a stylus while using the palm as a support - problems will occur. Since the palm covers a large area, it will block a large amount of infrared light, which causes difficulties for the infrared touch frame to accurately identify the exact position of the stylus and makes it impossible to accurately determine the actual contact point of the tip of the pen. Therefore, inaccurate positioning may occur during the writing process, affecting the user's writing experience.

[0042] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0043] To better understand the technical solutions of the present application, the following will be described in detail in combination with the accompanying drawings of the specification and specific embodiments.

[0044] The main solution of the embodiment of the present application is: identifying the signal type of the touch signal, where the signal type includes a nib signal; in the case where the touch signal is detected to include the nib signal, determining an anti-mis-touch area in the touch device based on the nib signal; reporting the target nib signal in the anti-mis-touch area.

[0045] In this embodiment, for the convenience of description, the following will be described with the touch device as the execution subject.

[0046] In a touch device using infrared technology, the writing operation relies on the precise occlusion of light to determine the position of the touch point. Specifically, when a user writes with a stylus, the system accurately locates the writing position by detecting the occlusion of infrared rays by the tip of the stylus. However, in practical applications, if a single user attempts to write in a natural way - that is, writing with a stylus while using the palm as a support - problems will occur. Since the palm covers a large area, it will block a large amount of infrared light, which causes difficulties for the infrared touch frame to accurately identify the exact position of the stylus and makes it impossible to accurately determine the actual contact point of the tip of the stylus. Therefore, inaccurate positioning may occur during the writing process, affecting the user's writing experience.

[0047] In summary, how to achieve anti-misoperation of writing in an infrared touch device to improve the user's writing experience has become an urgent problem to be solved in this field.

[0048] To address the above problems, this application provides an anti-misoperation method. When this application recognizes a touch signal, it identifies the type of the touch signal. Among them, the signal type includes a nib signal. When it is recognized that the touch signal includes a nib signal, it indicates that the user currently needs to write. At this time, an anti-misoperation area is determined in the touch device based on the nib signal. When reporting the signal, only the target nib signal in the anti-misoperation area is reported, and other touch signals in the anti-misoperation area are not reported, thus avoiding misoperation.

[0049] In summary, it can be seen that this application identifies the nib signal and generates an anti-misoperation area based on the nib signal in the touch signal. Compared with ordinary infrared touch devices, this application can generate an anti-misoperation area based on the nib signal, only report the nib signal in the anti-misoperation area, and do not report other touch signals in the anti-misoperation area, thus avoiding the problem of incorrect identification of the nib signal caused by palm misoperation.

[0050] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication, and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device, a touch device, etc. that can implement the above functions. Hereinafter, a touch device is taken as an example to illustrate this embodiment and the following embodiments.

[0051] Based on this, an embodiment of this application provides an anti-misoperation method, referring to Figure 1 , Figure 1 which is a schematic flowchart of the first embodiment of the anti-misoperation method of this application.

[0052] In this embodiment, the anti-misoperation method is applied to a touch device, and the anti-misoperation method includes steps S10 to S30:

[0053] Step S10, identify the signal type of the touch signal, where the signal type includes a nib signal;

[0054] It should be noted that in this embodiment, the touch device is mainly a touch screen device that uses infrared for identification. The infrared touch screen uses an infrared matrix densely arranged in the X and Y directions to detect and locate the user's touch. An infrared touch screen installs a circuit board frame in front of the display. The circuit board arranges infrared emitting tubes and infrared receiving tubes on the four sides of the screen, corresponding to each other to form a crossed infrared matrix. When the user touches the screen, the finger will block the infrared rays passing through that position, so the position of the touch point on the screen can be judged.

[0055] In this embodiment, the touch device first receives and analyzes touch signals from users or other external sources. These touch signals may be generated by various different input methods, including but not limited to finger touch, glove touch, nib (such as a stylus) touch, etc. The signal recognition module built into the device will conduct a detailed analysis of the received signals to determine their specific signal types. By accurately identifying the signal types of touch signals, the touch device can distinguish signals generated by different input methods. The recognition of the nib signal helps the device to perform more refined processing for specific input methods (such as writing, drawing, etc.).

[0056] Further, in a feasible implementation manner, please refer to Figure 2 , the signal type further includes: a palm signal; the above step S10 includes steps S11 to S13:

[0057] Step S11, when the touch signal is recognized, recognize the trigger area of the touch signal;

[0058] In this embodiment, since different types of input methods (such as a nib, a palm, etc.) usually generate different trigger areas, when the touch signal is received, the touch device will first measure the trigger area of the signal. The trigger area refers to the area occupied by the touch signal on the device screen, and it can be determined by analyzing the distribution and intensity of the signal on the screen.

[0059] Step S12, when the trigger area meets the first preset interval, determine that the touch signal is a nib signal;

[0060] In this embodiment, after measuring the trigger area of the touch signal, the device will compare it with the preset first preset interval. If the trigger area meets the first preset interval (that is, within the range of this interval), the device will determine that the touch signal is a nib signal. The first preset interval is usually set according to the size of the trigger area generated when the nib touches the screen to ensure accurate recognition of the nib signal. For example, the first interval can be set to 2mm to 10mm.

[0061] Step S13, when the trigger area meets the second preset range, determine that the touch signal is a palm signal, where the minimum value of the second preset range is greater than the maximum value of the first preset range.

[0062] In this embodiment, if the trigger area of the touch signal does not meet the first preset range but meets the preset second preset range, the device will determine that the touch signal is a palm signal. The minimum value of the second preset range is greater than the maximum value of the first preset range to ensure that the pen tip signal and the palm signal can be distinguished. The palm signal usually has a larger trigger area because the palm covers a larger area when touching the screen.

[0063] Further, after the above step S10, the method may further include step A10:

[0064] Step A10, when the palm signal is recognized, if the pen tip signal is recognized within a preset time, determine that the touch signal includes the pen tip signal.

[0065] In this embodiment, when the touch device recognizes the palm signal, it will enter a special monitoring state. In this state, the device will continuously monitor the change of the touch signal, especially whether the pen tip signal appears within the preset time. This preset time can be set according to the actual application scenario and user requirements to ensure that the action of the user switching from palm touch to pen tip writing can be captured.

[0066] If the device does recognize the pen tip signal within the preset time, then it will determine that the current touch signal does include the pen tip signal. This means that the user may be using a stylus for writing or drawing operations, and the previous palm signal may be caused by the user accidentally touching the screen with the palm or supporting on the screen. Through combined recognition, the device can more accurately recognize the user's true intention, thus avoiding misjudgment and misoperation.

[0067] In addition, in the operation logic of the touch device, if the system first recognizes the pen tip signal, then in the subsequent detection process, regardless of whether the palm signal is detected, as long as the pen tip signal does not disappear or interrupt, the system will continuously determine that the current touch signal contains the pen tip signal. This mechanism is based on the understanding and simulation of the user's operation behavior: when the user uses a stylus for writing, the palm may accidentally touch the screen surface; however, the user's intention is obviously to perform precise input through the pen tip.

[0068] From a technical principle perspective, this determination method relies on the real-time monitoring and analysis of the characteristics of different touch signals. Once the pen tip touches the screen and is recognized, the system will enter a state focused on tracking the position of the pen tip. Even if palm signals appear during this period - which usually means a larger contact area - as long as the pen tip signals remain continuous and stable, the system will not regard the palm contact as the main operation intention. Instead, it will continue to use the pen tip as the main interaction point to respond to the user's input actions. This method not only improves the convenience and naturalness of users when writing or drawing, but also reduces operation errors caused by accidental touches.

[0069] Step S20, when it is detected that the touch signal includes the pen tip signal, determine an anti-accidental touch area in the touch device based on the pen tip signal;

[0070] In this embodiment, after detecting that the touch signal contains the pen tip signal, the touch device will dynamically determine an anti-accidental touch area on the device screen according to the specific position and movement trajectory of the pen tip signal. This area can be centered around the center point of the pen tip signal and has a certain expansion range to ensure that when the pen tip performs fine operations, even if the user's finger or other objects touch the screen, they will not be misrecognized as valid input. By dynamically determining the anti-accidental touch area based on the pen tip signal, the touch device can significantly reduce the probability of accidental touches during pen tip operations and improve the accuracy and comfort of user input.

[0071] Furthermore, in a feasible implementation manner, the above step S20 may include steps S21 to S22:

[0072] Step S21, real-time identify the graphic center of the pen tip signal;

[0073] In this embodiment, when it is detected that the touch signal contains the pen tip signal, the touch device will enter a real-time recognition mode. In this mode, the device will continuously and dynamically analyze the position and shape of the pen tip signal on the screen to real-time determine the graphic center of the pen tip signal. The graphic center usually refers to the geometric center point of the pen tip signal on the screen, which reflects the specific position where the pen tip currently touches the screen.

[0074] Step S22, determine a target area with a preset size in the touch device based on the graphic center and use the target area as the anti-accidental touch area.

[0075] In this embodiment, after real-time identifying the graphic center of the pen tip signal, the touch device will determine a target area around the graphic center according to the preset size and shape. This target area is the anti-accidental touch area, which is used to shield the accidental touch signals that may be generated by the user's finger or other objects.

[0076] The size and shape of the anti - accidental touch area can be set according to the actual application scenario and user requirements. For example, in a drawing application that requires high - precision input, the anti - accidental touch area may be set relatively small to ensure that the user can accurately control the position of the pen tip; while in a handwritten note application that requires fast input, the anti - accidental touch area may be set relatively large to reduce the possibility of accidental touch by the user's palm.

[0077] Further, in a feasible implementation, step S21 described above may include step B10:

[0078] Step B10, determine a circular target area with a preset size in the touch device centered on the center of the graphic, and use the circular target area as the anti - accidental touch area.

[0079] In this embodiment, after the center of the graphic of the pen - tip signal is recognized in real - time, the touch device will further determine a circular target area with a preset size centered on the center of this graphic. This circular target area is the anti - accidental touch area, which is used to shield the accidental touch signals that may be generated by the user's finger or other objects around the pen tip.

[0080] The size of the circular anti - accidental touch area can be set according to the actual application scenario and user requirements. Usually, this size will be large enough to ensure that it can cover the screen area that the user's finger may touch during writing or drawing, but not too large so as not to affect other normal operations of the user.

[0081] Through the above steps, the touch device can more accurately determine the circular anti - accidental touch area centered on the center of the graphic, improving the efficiency of anti - accidental touch.

[0082] In another feasible implementation, step S21 described above may also include steps C10 - C20:

[0083] Step C10, identify the moving speed and moving direction of the center of the graphic;

[0084] In this embodiment, after the center of the graphic of the pen - tip signal is recognized in real - time, the touch device will further analyze the moving speed and moving direction of the center of this graphic. The moving speed reflects how fast the pen tip moves on the screen, and the moving direction indicates the moving trajectory of the pen tip.

[0085] Step C20, determine an elliptical target area with a preset size in the touch device according to the moving direction of the center of the graphic, and use the elliptical target area as the anti - accidental touch area, where the major - axis length of the elliptical target area is positively correlated with the moving speed.

[0086] In this embodiment, after identifying the moving speed and direction of the center of the graphic, the touch device determines an elliptical target area with a preset size on the screen as the anti-mis-touch area according to this information. The length of the major axis of the ellipse is positively correlated with the moving speed of the center of the graphic, that is, the faster the moving speed, the longer the major axis of the ellipse; conversely, the slower the moving speed, the shorter the major axis of the ellipse. The length of the minor axis of the ellipse can remain fixed or be appropriately adjusted according to actual needs.

[0087] The design of the elliptical anti-mis-touch area takes into account the dynamic characteristics of the pen tip during movement. When the user writes or draws quickly, the movement trajectory of the pen tip may be wider, so a larger anti-mis-touch area is required to shield mis-touch signals. When the user moves the pen tip slowly, the anti-mis-touch area can be correspondingly reduced to reduce interference with normal operations.

[0088] At the same time, the direction of the major axis of the ellipse is consistent with the moving direction of the center of the graphic, which helps to ensure that the anti-mis-touch area can cover both sides of the movement trajectory of the pen tip, thereby more effectively shielding mis-touch signals.

[0089] Through the above steps, the design of the elliptical anti-mis-touch area can be dynamically adjusted according to the moving speed and direction of the pen tip, which helps to ensure that the anti-mis-touch area can always cover the potential mis-touch areas around the pen tip, thereby improving the accuracy and efficiency of input.

[0090] The above are only two feasible implementation manners of step S21 provided in this embodiment, and the specific implementation manner of step S21 in this embodiment is not specifically limited.

[0091] Step S30, report the target pen tip signal in the anti-mis-touch area.

[0092] In this embodiment, after determining the anti-mis-touch area, the touch device further filters out the pen tip signals located in this area as target signals. These target signals are the effective inputs made by the user through the pen tip or other similar objects. The device will report them to the upper-layer application or system for processing. At the same time, the device will ignore other signals in the anti-mis-touch area to avoid interference caused by mis-touch. By reporting the target pen tip signal in the anti-mis-touch area, the touch device can ensure that the user's effective input is accurately recognized and transmitted to the upper-layer application or system, while filtering out irrelevant signal interference.

[0093] Further, after the above step S30, the method may further include steps S40 to S50:

[0094] Step S40, adjust the thickness of the handwriting display in the touch device according to the triggering area of the target pen tip signal;

[0095] In this embodiment, the touch device has reported the target nib signals in the anti-mis-touch area. On this basis, the device will further analyze the trigger area of these target nib signals. The size of the trigger area is usually related to the contact area between the nib and the screen, which can reflect the writing force and style of the user. According to the trigger area of the target nib signals, the touch device will adjust the thickness of the handwriting display. Specifically, if the trigger area is large, the device can set the handwriting to be thicker to simulate the effect of the user writing forcefully; if the trigger area is small, the device can set the handwriting to be thinner to reflect the user's gentle writing style. By adjusting the thickness of the handwriting display according to the trigger area of the target nib signals, the touch device can provide a more realistic and natural writing experience for the user.

[0096] Step S50, display the signal trajectory of the target nib signal in the touch device based on the thickness.

[0097] In this embodiment, after adjusting the thickness of the handwriting display, the touch device will display the signal trajectory of the target nib signal according to these settings. The signal trajectory refers to the path left by the nib when moving on the screen, which reflects the user's writing or drawing process. The device will draw the corresponding handwriting on the screen according to the thickness to present the writing effect expected by the user. This display method not only provides instant visual feedback but also allows the user to intuitively see the result of their writing or drawing.

[0098] In addition, in the operation mechanism of the touch device, if the system fails to detect the presence of the nib signal but recognizes the palm signal, it will automatically regard this palm contact as an eraser command. Specifically, when the user touches the screen only with the palm without using a stylus, the system will consider this as an intention to clear the existing handwriting on the screen and trigger the corresponding eraser function accordingly.

[0099] Exemplarily, to help understand the implementation process of the anti-mis-touch method obtained by combining this embodiment with the above Embodiment 1, please refer to Figure 3 , Figure 3 A brief flowchart of the anti-mis-touch method is provided, specifically:

[0100] When writing on the whiteboard, first determine whether a palm falls within the touchable range of the all-in-one machine. At this time, the infrared touch will recognize that an area is blocked by the palm, and it can be determined that a palm has fallen. When the palm is recognized to have fallen, the timing starts: when the pen tip is recognized to have fallen near the palm within 0.6S, the touch data of the pen tip will be reported to the application layer, and the area recognition within the radius of 20cm with the pen tip as the center will be shielded. Only the touch data of the pen tip will be reported, and the hand can be held within the touch screen range to write with the touch pen. When the 0.6S time is up, but the pen tip signal has not been recognized, the touch data of the touch screen will be reported normally.

[0101] When the palm does not fall first, it is necessary to determine whether a thick pen or a thin pen falls within the range of the touch screen first. If not, the thick pen or the thin pen falls within the range of the touch screen, and the touch screen data is reported normally; when a thick pen or a thin pen falls within the range of the touch screen, the timing starts at this time. If a palm falls within 0.6S, the touch data of the pen tip is reported to the application layer, and the area recognition within the range of 20cm with the pen tip as the center of the circle is shielded. Only the touch data of the pen tip is reported, and the hand can be held within the range of the touch screen to write with the touch pen; if the palm falls after 0.6S, it is necessary to determine whether the pen tip that fell before is lifted up again. If it is not lifted up, the anti-mistouch mode is entered again to start reporting the touch data of the pen tip to the application layer, and the area recognition within the range of 20cm with the pen tip as the center of the circle is shielded. Only the touch data of the pen tip is reported, and the hand can be held within the range of the touch screen to write with the touch pen; if the palm falls after 0.6S, it is necessary to determine whether the pen tip that fell before is lifted up again. If it is not lifted up, the anti-mistouch mode is entered again to start reporting the touch data of the pen tip to the application layer, and the area recognition within the range of 20cm with the pen tip as the center of the circle is shielded. Only the touch data of the pen tip is reported, and the hand can be held within the range of the touch screen to write with the touch pen;

[0102] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the method for preventing accidental touches of the present application. More simple transformations based on this technical concept are all within the protection scope of the present application.
