Description

Technical Field

[0001] The present invention relates to the field of touch technology, and in particular to a touch pressure degree recognition method, a touch pressure operation control method, a computer device and a storage medium. Background Art

[0002] With the continuous advancement of automotive technology, vehicle intelligence has become a core issue in the development of today's automotive industry. In this context, the displays equipped inside the car and those smart surfaces that cleverly combine decorative aesthetics and practical functions, such as door trims, dashboards, steering wheels, etc., are bringing users unprecedented intelligent and convenient driving experience, greatly promoting the friendliness and humanized design of the human-computer interaction interface. The emergence of touch chip technology marks a profound change in the traditional button operation method. Touch operation is more flexible and comfortable. At the same time, the design of the display panel is increasingly tending to be fashionable and visually attractive. The gradual replacement of physical buttons by touch buttons in display panels is undoubtedly an inevitable trend and direction of technological development.

[0003] At the application level of display panels, different levels of touch pressure have opened up a broad space for diversified applications and interactive designs. Specifically, users can select and switch multiple functions in the same operation by applying different levels of pressure. For example, lightly touching the screen to realize the preview function, and heavy pressure directly opens the target application. This design greatly simplifies the operation process and improves the operation efficiency. At the same time, it also effectively reduces the user's usage cost and learning threshold. At present, in the field of touch pressure degree recognition technology, the mainstream method relies on pressure sensors to detect the pressure applied by the user's finger on the display panel to determine the degree of touch pressure. Unfortunately, however, this method of detecting the pressure force faces the disadvantage that the user may need to apply a large force to trigger the operation in actual application, which will cause user fatigue after long-term use.

[0046] Embodiment 1

[0047] In view of the defects of the above-mentioned prior art, the applicant, based on many years of rich practical experience and professional knowledge in this field, and in conjunction with the application of theory, actively conducts research and innovation in the hope of creating a technology that can solve the defects of the prior art. After continuous research and design, and after repeated trial production and improvement, the present invention with real practical value was finally created.

[0048] Please refer to Figure 1 , is a flow chart of a touch pressure degree recognition method provided in Embodiment 1 of the present invention, which is applicable to a scenario where a user performs touch control on a display panel. The method specifically comprises the following steps:

[0049] S101 : Detecting the contact area between the user's finger and the display panel.

[0050] It should be noted that this step, as the basis of the entire recognition process, uses high-precision sensor technology to accurately detect the actual contact area between the user's finger and the display panel. The implementation of this step provides key data support for the subsequent determination of the touch pressure degree.

[0051] For step S101, this embodiment provides a variety of detailed and feasible implementation strategies, each of which is based on different sensor technologies and principles to adapt to different application scenarios and requirements, but can ultimately determine the contact area between the user's finger and the display panel. The following is a detailed description of these implementation strategies:

[0052] In the first implementation strategy, step S101 can be further refined into the following contents:

[0053] The image when the user's finger contacts the display panel is detected by a visual sensor arranged on the display panel, so as to determine the contact area between the user's finger and the display panel.

[0054] It should be noted that in this implementation strategy, high-precision visual sensors are first integrated at appropriate locations on the display panel. These visual sensors have the characteristics of high resolution and fast response, and can capture and record image information when the user's finger touches the display panel in real time. In order to improve the accuracy and stability of recognition, advanced image processing algorithms and machine learning technologies can be used to carefully analyze and process the captured images.

[0055] Specifically, when the user's finger touches the display panel, the visual sensor captures the image at that time. Subsequently, the image processing algorithm pre-processes the image, including steps such as denoising and contrast enhancement, to ensure the accuracy of subsequent analysis. Then, the algorithm uses edge detection, shape recognition and other technologies to accurately outline the contours of the user's finger touching the display panel.

[0056] After obtaining the contact contour, mathematical calculation models such as polygonal approximation and pixel counting are used to calculate and determine the actual contact area between the user's finger and the display panel. This process not only relies on advanced algorithms and models, but also requires a lot of experimental data and calibration work to ensure the accuracy and reliability of the calculation results.

[0057] Through this detailed and specific implementation step, the contact area of ​​the user's finger can be quickly and accurately determined when the finger contacts the display panel.

[0058] In the second implementation strategy, step S101 can be further refined into the following contents:

[0059] The strain amount generated by the deformation of the display panel due to force is detected by a strain sensor arranged on the display panel, so as to determine the contact area between the user's finger and the display panel.

[0060] It should be noted that in this implementation strategy, a series of strain sensors are first cleverly arranged on the back or edge area of ​​the display panel. These strain sensors have high sensitivity and high precision, and can sense in real time the tiny deformation of the display panel caused by the user's finger pressing. In order to improve the accuracy and stability of recognition, advanced signal processing technology and data analysis algorithms can be used to carefully analyze and process the data captured by the strain sensors.

[0061] Specifically, when the user presses the display panel with his finger, the display panel will produce a certain deformation in the contact area, and this deformation will be immediately captured by the strain sensor. Subsequently, the signal processing algorithm will perform pre-processing steps such as filtering and amplification on these strain signals to eliminate noise interference and enhance signal strength. Then, the data analysis algorithm will use the mechanical model and strain-displacement relationship to convert the strain signal into the degree of deformation of the display panel, that is, the strain amount.

[0062] After obtaining the strain, the actual contact area between the user's finger and the display panel is estimated using contact mechanics principles and mathematical calculation models, such as Hertz contact theory and finite element analysis. This process not only relies on accurate mechanical and calculation models, but also requires a large amount of experimental data and calibration work to ensure the accuracy and reliability of the estimated results.

[0063] Through this detailed and specific implementation step, the contact area of ​​the user's finger can be quickly and accurately determined when the user presses the display panel. At the same time, since the strain sensor is usually arranged on the back or edge of the display panel, it will not have any negative impact on the visual effect and user experience of the display panel.

[0064] In the third implementation strategy, step S101 can be further refined into the following contents:

[0065] The capacitive sensor disposed on the display panel detects the change in electrostatic capacitance formed between the user's finger and the display panel, thereby determining the contact area between the user's finger and the display panel.

[0066] It should be noted that in this implementation strategy, a capacitive sensor array is first integrated on the surface or inside of the display panel. These capacitive sensors are composed of a series of tiny electrodes that can sense and measure the changes in electrostatic capacitance formed between the user's finger and the display panel. In order to improve the accuracy and stability of recognition, advanced capacitance measurement technology and data processing algorithms can be used to analyze and process the data captured by the capacitive sensor in real time.

[0067] Specifically, when a user's finger approaches or touches the display panel, a tiny electrostatic capacitor is formed between the human body and the display panel because the human body is conductive. The size of this capacitance depends on factors such as the distance between the user's finger and the display panel, the contact area, and the dielectric constant between the two. Capacitive sensors can measure the change in this capacitance in real time and convert it into an electrical signal for output.

[0068] The data processing algorithm then performs pre-processing steps such as filtering and amplification on these electrical signals to eliminate noise interference and enhance signal strength. The algorithm then uses the relationship model between capacitance and contact area, such as the parallel plate capacitor formula, to convert the change in capacitance into the contact area between the user's finger and the display panel.

[0069] After obtaining the contact area, this data can be further used to determine the degree of touch pressure of the user's finger, thereby achieving a more accurate and sensitive touch interaction experience. Since capacitive sensors have the advantages of fast response speed, low power consumption, and easy integration, this implementation strategy is conducive to the widespread application of touch technology.

[0070] Through this detailed and specific implementation step, the contact area of ​​the user's finger can be quickly and accurately determined when the finger contacts the display panel.

[0071] In the fourth implementation strategy, step S101 can be further refined into the following contents:

[0072] The electric field sensor disposed on the display panel detects the change in electric field strength caused by the user's finger contacting the display panel, thereby determining the contact area between the user's finger and the display panel.

[0073] It should be noted that in this implementation strategy, an electric field sensor array is first arranged around or inside the display panel. These electric field sensors can sense and measure the changes in electric field strength caused by the user's finger touching the display panel. In order to improve the accuracy and stability of recognition, advanced electric field measurement technology and signal processing algorithms can be used to analyze and process the data captured by the electric field sensor in real time.

[0074] Specifically, when the user's finger touches the display panel, the human body is conductive, which changes the electric field distribution around the display panel, resulting in a change in the electric field strength. This change is related to factors such as the contact area and contact position of the user's finger and the electrical characteristics of the display panel. The electric field sensor can measure the change in the electric field strength in real time and convert it into an electrical signal for output.

[0075] Subsequently, the signal processing algorithm will filter and amplify these electrical signals to eliminate noise interference and enhance signal strength. Then, the algorithm will use the relationship model between electric field strength and contact area, which may be based on the fitting results of experimental data or the derivation of electromagnetic field theory. Through this model, the change in electric field strength can be converted into the contact area between the user's finger and the display panel.

[0076] After obtaining the contact area, this data can be further used to determine the degree of touch pressure of the user's finger, thereby achieving a more accurate and sensitive touch interaction experience. Since electric field sensors have the advantages of fast response speed, wide measurement range, and no influence from ambient light, this implementation strategy can maintain high recognition accuracy even in complex environments and lighting conditions.

[0077] Through this detailed and specific implementation step, the contact area of ​​the user's finger can be quickly and accurately determined when it touches the display panel. At the same time, the introduction of electric field sensor technology has also brought new possibilities and innovative directions to the development of touch technology.

[0078] In the fifth implementation strategy, step S101 can be further refined into the following contents:

[0079] The infrared matrix area blocked by the user's finger is detected by an infrared matrix sensor arranged on the display panel, so as to determine the contact area between the user's finger and the display panel.

[0080] It should be noted that in this implementation strategy, an infrared matrix sensor layer is first cleverly set above or below the display panel (usually below to avoid interfering with the display effect). This sensor layer consists of a series of tiny infrared transmitters and receivers arranged in a matrix form that can emit and receive infrared signals. When the user's finger touches or approaches the display panel, it will block part of the transmission path of the infrared signal, thereby changing the transmission state of the infrared matrix.

[0081] Specifically, the infrared transmitter periodically emits infrared signals, which should be received by the corresponding receiver after passing through the air. However, when the user's finger touches the display panel, it blocks the transmission of part of the infrared signal, causing the signal strength received by the receiver to weaken or disappear completely. The infrared matrix sensor can sense the changes in the signal transmission state in real time and convert it into electrical signals for output.

[0082] The data processing algorithm will then analyze and process these electrical signals. First, the algorithm will identify which infrared signal transmission is blocked, thereby determining the blocked infrared matrix area. Then, the algorithm will use the shape, size and other information of this area, combined with the geometric calculation model, to calculate the actual contact area between the user's finger and the display panel.

[0083] After obtaining the contact area, this data can be further used to determine the degree of touch pressure of the user's finger, thereby providing users with a more accurate and sensitive touch interaction experience. Since the infrared matrix sensor has the advantages of being unaffected by ambient light, high measurement accuracy, and fast response speed, this implementation strategy can maintain high recognition accuracy in complex lighting conditions and fast touch scenarios.

[0084] Through this detailed and specific implementation step, the contact area of ​​the user's finger can be quickly and accurately determined when it touches the display panel. At the same time, the introduction of infrared matrix sensor technology has also brought new opportunities and challenges to the development of touch technology.

[0085] In one implementation of this embodiment, Figure 1 Based on the basic process shown in FIG. 1 , a more detailed improvement is made. Specifically, before step S101, a crucial pre-step S100 is added to effectively prevent the occurrence of accidental touch operations, thereby ensuring the accuracy and safety of the touch control system. This improvement is as follows Figure 2As shown, the logical relationship between the newly added steps and the original steps is clearly demonstrated.

[0086] Specifically, the step S100 is:

[0087] S100, when it is detected that the display panel is touched by a contact object, identifying whether the contact object has fingerprint information; if so, executing step S101; if not, not executing any operation.

[0088] It should be noted that when it is detected that the display panel is in contact with a contact body (which may be a human body or an object), the fingerprint information recognition mechanism will be immediately activated. This mechanism uses advanced fingerprint recognition technology to accurately capture and identify fingerprints on the surface of the contact body. If the recognition result shows that there is fingerprint information on the contact body, that is, it is confirmed that the contact body is a finger with fingerprint information, then the system will continue to execute the subsequent step S101 to further determine the contact area and touch pressure degree between the finger and the display panel. However, if the recognition result shows that there is no fingerprint information on the contact body, that is, the contact body may be an object or a part of the human body other than a finger, then it will be determined as a false touch, and the subsequent operations will be automatically terminated without executing any touch-related processing flow.

[0089] The addition of this pre-step S100 not only significantly improves the accuracy and safety of the touch system, but also effectively avoids the problem of misoperation caused by accidental touch. Through the recognition and verification of fingerprint information, the system can more accurately determine whether the contact object is the user's finger, thereby ensuring that only the user's finger touches to trigger the touch operation.

[0090] In summary, this embodiment achieves accurate recognition of touch operations and effective prevention of false touches by adding the pre-step S100, thereby providing a more reliable basis for subsequent determination of the touch pressure degree.

[0091] S102: Determine the touch pressure degree of the user's finger according to the contact area.

[0092] It should be noted that after obtaining the contact area data, the present invention uses advanced technologies, such as query matching or algorithm models, to accurately match the contact area with the degree of pressure of the user's finger. This process not only relies on a large amount of experimental data and scientific analysis, but also fully considers ergonomic principles to ensure the accuracy and reliability of the recognition results.

[0093] In an implementation of this embodiment, the step S102 may be further refined into the following contents:

[0094] In a preset first corresponding database, the touch pressure degree having a corresponding relationship with the contact area is searched and determined; the first corresponding database stores the corresponding relationship between the contact area and the touch pressure degree.

[0095] It should be noted that in step S102, a preset first corresponding database is first relied on. This database is pre-built and stored in the system, and contains a large amount of corresponding relationship data between contact area and touch pressing degree. These data are obtained through experimental measurement, statistical analysis, and machine learning algorithm optimization, ensuring their accuracy and reliability.

[0096] When the user's finger contacts the display panel and the specific contact area has been determined in step S101, the detailed process of step S102 will be entered next. In this process, the system will first access the first corresponding database and search for the touch pressure degree that has a direct correspondence relationship with the current contact area.

[0097] To achieve this search process, each record in the database contains a specific contact area value and the corresponding touch pressure value. The system will execute an efficient search algorithm in the database to find the record that best matches the currently determined contact area. Once such a record is found, the system will immediately read and record the touch pressure value in the record as the current user's finger touch pressure accuracy.

[0098] This search method based on a preset database not only greatly simplifies the process of determining the touch pressure level, but also significantly improves its accuracy and efficiency. By building and optimizing this first correspondence database in advance, it can ensure that the touch pressure level corresponding to the current contact area can be found quickly and accurately in any case, thus providing users with a smoother and more accurate touch interaction experience.

[0099] In summary, this embodiment achieves rapid and accurate determination of the touch pressing degree by refining step S102 and introducing a preset first corresponding database, thereby providing more reliable data support for subsequent touch operations.

[0100] Although the terms such as touch, contact area, and press are frequently used in this application, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.

[0101] The unique feature of the touch pressure degree recognition method provided by the embodiment of the present invention is that it no longer relies on the traditional pressure force detection technology, but cleverly uses the contact area, which is more intuitive and easy to detect data, to indirectly reflect the user's touch pressure degree. This innovative design not only significantly improves the accuracy of recognition, but more importantly, it achieves low requirements for user operation force. Users can complete touch operations without applying excessive pressure, which not only greatly reduces hand fatigue during long-term use, but also further improves the comfort and satisfaction of user experience.

[0102] Given the excellent performance of the present invention in ensuring efficient and accurate recognition and optimizing user experience, it undoubtedly has a wide range of application potential. Whether it is mobile devices such as smartphones and tablets, or emerging fields such as smart homes and car systems, the present invention can provide them with a more intelligent and more human touch interaction experience. Therefore, the present invention is suitable for promotion and implementation in a wide range of fields to promote the further development and innovation of touch technology.

[0103] Embodiment 2

[0104] Please refer to Figure 3 , Embodiment 2 of the present invention provides a method for controlling a touch pressing operation. The method aims to provide a more accurate and personalized touch interaction experience for the user by accurately identifying the degree of touch pressing when the user's finger contacts the display panel and performing corresponding touch operations accordingly. The following are the detailed steps of the method:

[0105] S201 : using the touch pressure degree recognition method provided in the first embodiment to recognize the touch pressure degree when the user's finger contacts the display panel.

[0106] It should be noted that in this step, the touch pressure degree recognition method described in the first embodiment is used. This method can accurately identify the touch pressure degree applied by the user's finger when contacting the display panel through a series of precise steps, including the determination of the contact area and the search based on the preset database. The accuracy of this step is the basis of the entire control method and the key to achieving accurate execution of subsequent touch operations.

[0107] S202: Searching a preset second corresponding database for a touch operation corresponding to the touch pressure degree; the second corresponding database stores the corresponding relationship between the touch pressure degree and the touch operation.

[0108] It should be noted that in this step, a preset second correspondence database is introduced. This database is pre-built and stored in the system, and it contains the correspondence between the touch pressure degree and the touch operation. These correspondences are obtained through experimental measurement, user habit analysis, and system optimization, ensuring their accuracy and practicality.

[0109] When the user's finger touches the display panel and the specific touch pressure level has been determined in step S201, the query process of step S202 will be entered next. In this process, the system will first access the second corresponding database and search for a touch operation that has a direct correspondence relationship with the current touch pressure level. Once such a correspondence is found, the system will immediately read and record the touch operation as the next control instruction to be executed on the display panel.

[0110] S203: Execute the control operation on the display panel.

[0111] It should be noted that in this step, the corresponding control instructions are executed on the display panel according to the touch operation queried in step S202. These control instructions may include various touch operations such as opening an application, adjusting the volume, and sliding a page, depending on the touch pressure of the user's finger and the preset corresponding relationship.

[0112] By executing this step, the degree of touch pressure of the user's finger can be directly converted into actual operation on the display panel, thereby achieving accurate and personalized touch interaction. This control method not only improves the accuracy and efficiency of touch operation, but also brings users a smoother and more natural touch experience.

[0113] In summary, the second embodiment of the present invention realizes an innovative touch pressure control method by adopting an accurate touch pressure degree recognition method, a preset corresponding database and an efficient touch operation execution process.
