Description

Technical Field

[0001] This invention relates to the field of human-computer interaction technology, and in particular to a touch interaction control method, device, computer equipment, and storage medium. Background Technology

[0002] With the continuous development of in-vehicle display technology, dual-view display technology is gradually being applied to smart cockpits. This technology allows the driver and front passenger to observe different visual content on the same display screen; for example, the driver can view navigation information while the front passenger views multimedia entertainment content.

[0003] However, existing touch interaction technologies have significant limitations when adapted to dual-view displays. Current touchscreens (such as capacitive touchscreens) primarily determine the touch position by detecting changes in electrical charge. Their driver ICs can only report the coordinates of the touch point and cannot distinguish whether the current touch operation is from the driver or the passenger. This often leads to confusion in interaction logic in practical applications. For example, while the passenger is watching a video, their touch action might be interpreted as an operation on the driver's navigation interface, thus interfering with the driver's normal driving.

[0004] While people can be distinguished by adding camera recognition or biometric identification, these solutions typically face challenges such as high computational demands, high costs, strong dependence on lighting conditions, and privacy protection concerns. Therefore, how to achieve accurate identification of users and control of interaction permissions for in-vehicle touchscreen operations in a low-cost and efficient manner is a pressing technical problem that needs to be solved.

For those skilled in the art to which this application pertains, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0030] Please refer to Figure 1 This invention provides a touch interaction control method, which, for example, is specifically applied to a vehicle interaction environment with dual-view display function.

[0031] In this embodiment, the control method includes: S1. Upon receiving a touch operation, obtain the position information corresponding to the touch operation, as well as the identification signal coupled with the touch operation; S2. Identify the operating entity attribute of the touch operation based on the identification signal; S3. Execute the corresponding response action based on the preset permissions of the functional components corresponding to the operation subject attributes and location information.

[0032] Based on the aforementioned steps, upon receiving a touch operation, not only is the location information corresponding to the touch operation (such as the X and Y coordinates of the touch point on the screen) acquired, but also the identification signal coupled with the touch operation is acquired. Then, based on the identification signal, the operation subject attribute of the touch operation is identified, such as determining whether it is the driver or the co-driver operating the operation, and according to the operation subject attribute and the preset permissions of the functional components corresponding to the location information, the corresponding response action is executed.

[0033] Understandably, this embodiment introduces an identity feature signal bound to physical human contact on top of traditional touch coordinates. This upgrades touch data from a single location dimension to dual-dimensional data combining location and identity, enabling different interaction permissions to be assigned based on the operator's identity on the same display screen. Therefore, this embodiment fundamentally solves the problem of interaction conflict between the driver and passenger in a dual-screen environment, avoiding safety hazards such as the passenger accidentally touching the driver's navigation function while watching entertainment content.

[0034] In one optional embodiment of this invention, the identification signal is generated by a signal source preset at the operation position and transmitted to the touch interface through the human body located at the operation position.

[0035] Specifically, when an operator sits in a chair equipped with a signal source, the human body, due to its conductivity, can sense and carry the electrical signal emitted by the signal source, acting as a resistor or conductor. When the operator touches the touch component (such as a capacitive screen) with their finger, this electrical signal enters the touch system through the mutual capacitance or self-capacitance coupling between the skin and the screen electrodes. In other words, based on the principle of human body conduction, a corresponding identification signal is generated without the need for additional cameras or complex biometric modules, resulting in a simple structure, extremely low power consumption, and timely recognition.

[0036] In one optional implementation of this embodiment, in step S3, according to the preset permissions of the functional components corresponding to the operation subject attributes and location information, a corresponding response action is executed, including: If the attributes of the operation subject meet the triggering permissions of the functional component, then the corresponding functional event of the functional component will be triggered. If the attributes of the operation subject do not meet the triggering permissions of the functional component, then the touch operation is filtered.

[0037] Please refer to Figure 2 For example, in a dual-view in-vehicle scenario, the map navigation interface displayed on the driver's side belongs to the high-priority control area, while the multimedia entertainment interface displayed on the passenger's side belongs to the low-priority area. When the system detects that the current touch location corresponds to a button on the map navigation interface, and the identified operator is the passenger, the touch command will be intercepted and filtered because the passenger does not have the necessary permissions to trigger that function, rendering the button unclickable or unresponsive. This approach of separating permissions ensures that critical driving control of the vehicle is always in the hands of the correct person, improving driving safety.

[0038] In one optional implementation of this embodiment, identifying the operation subject attribute of the touch operation based on the identification signal includes: When an identification signal is detected and the strength of the identification signal is greater than a preset threshold, the operation subject attribute is determined to be the first attribute; When no identification signal is detected, or when the intensity of the detected identification signal is not greater than a preset threshold, the operation subject attribute is determined to be the second attribute.

[0039] In this embodiment, to ensure the robustness of the identification, a threshold determination mechanism based on signal strength is adopted. That is, when an identification signal is detected and the signal strength is greater than a preset threshold, the operator's attribute is determined to be the first attribute (such as the co-driver); when no identification signal is detected, or the signal strength is not greater than the preset threshold, the operator's attribute is determined to be the second attribute (such as the driver).

[0040] Understandably, the aforementioned solution is based on safety considerations in the in-vehicle environment, hence the signal activation unit is installed in the passenger seat, but not in the driver's seat. When the user in the passenger seat performs a touch operation, the signal is transmitted directly to the body through the seat cushion, and the system can only execute a response when it detects a strong specific identifier signal. If no identifier signal is detected or the signal strength is not greater than a preset threshold, it is determined to be the driver, ensuring that the driver does not lose control of the screen in extreme situations.

[0041] In one optional implementation of this embodiment, to avoid low-frequency noise interference from electronic devices such as motors and windshield wipers in the vehicle environment, the identification signal includes a square wave signal with a preferred frequency of 150kHz. Since 150kHz is in the mid-to-long wave band, it ensures efficient conduction through the human body and is easily separated from conventional touch excitation signals by the touch driver IC using a bandpass filtering algorithm. Therefore, using a square wave signal facilitates edge trigger detection and feature matching by the driver IC, thereby achieving a high signal-to-noise ratio for identity recognition.

[0042] Please refer to Figure 3 Based on the above embodiments, the present invention also provides a touch interaction control device for implementing the touch interaction control method of any of the above claims, comprising: The signal activation unit 10 is used to provide an identification signal in a specific operating area so that the operator in the specific operating area carries the identification signal. Touch unit 20 is used to sense the position information corresponding to the touch operation and couple an identification signal when a touch operation is received; The identification unit 30 is used to identify the operation subject attribute of the touch operation based on the identification signal; The execution unit 40 is used to execute corresponding response actions based on the preset permissions of the functional components corresponding to the operation subject attributes and location information.

[0043] In one optional embodiment of this invention, the signal activation unit is arranged on the seat cushion of the seat 50, and the operator's body is used as a conductive medium to transmit the identification signal to the touch unit 20.

[0044] Please refer to Figure 4 It is understood that the signal excitation unit 10 is arranged on the seat 50, either below the seat 50 or on the seat back. Since the user is basically in a seated position when operating the central control screen, and the contact area between the body and the seat cushion is the largest, preferably, the signal excitation unit 10 is arranged on the seat cushion of the seat 50. This arrangement of the signal excitation unit 10 ensures that the signal is stably loaded onto the human body. The signal excitation unit 10 is connected to the vehicle battery for power supply, and because it only needs to generate a weak carrier signal, the power consumption of the device itself is greatly reduced. In another embodiment, the touch interaction control device can support multi-area recognition. For example, if the vehicle has a three-row seat layout, excitation units emitting signals of different specific frequencies (such as 150KHz, 180KHz, and 200KHz) are arranged in the front passenger seat, the left rear seat, and the right rear seat, respectively. By extracting the frequency components of the coupled signal in the touch operation, the recognition unit 30 can accurately distinguish which seat the current operation comes from, thereby achieving more refined multi-device linkage control in the vehicle.

[0045] In another embodiment, the identification of the subject attribute of the touch operation based on the identification signal further includes allocating operation permissions according to different specific frequencies, specifically including: Identify the frequency value of the identification signal; Based on the preset mapping relationship between frequency and permissions, determine the operation subject attribute and the corresponding permission set corresponding to the frequency value; The different frequency values ​​correspond to the driver, the front passenger, or the rear passenger, respectively. The driver's permission set includes driving control permissions, while the front passenger's and the rear passenger's permission sets do not include driving control permissions.

[0046] Specifically, the signal activation unit emits different frequency identification signals depending on its installation location. For example, the activation unit in the driver's seat emits a 200 kHz signal, granting full access to the touch-screen interactive control device; the front passenger seat emits a 180 kHz signal, granting only entertainment access; and the rear seats emit a 150 kHz signal, granting only entertainment access. This prevents accidental operation of critical functions of the touch-screen interactive control device by the front passenger or rear passengers.

[0047] After capturing the signal, the recognition unit performs frequency analysis. If the frequency is 200 kHz, it is determined to be the driver, and the execution unit grants operating permissions including screen gear shifting and driver assistance settings. If the frequency is 180 kHz or 150 kHz, the execution unit only grants non-driving control permissions such as air conditioning adjustment and audio-visual entertainment.

[0048] For example, the screen shift function is configured only for drivers with a 200kHz operating frequency, allowing them to use the screen shift function, while the front passenger and rear passengers cannot use the screen shift function to avoid interfering with driving safety.

[0049] In another embodiment, the touch interaction device further includes a capacitive touch sensor and a wake-up device; the capacitive touch sensor is used to trigger the wake-up device to send a pulse signal to the excitation unit when a touch operation is sensed; the signal excitation unit responds to the wake-up signal, switches from a sleep state to a working state, and continuously emits the identification signal for a preset time until the preset time ends and re-enters the sleep state.

[0050] Specifically, the touch interaction device includes a capacitive touch sensor and a wake-up device. To reduce system static power consumption and extend the lifespan of electronic components, the signal excitation unit is initially in a low-power sleep mode, during which it stops emitting signals. When a user touches the touch interaction device, the capacitive touch sensor senses the change in electrical signal as the user's finger approaches or touches the screen, triggering the wake-up device to send a pulse signal, i.e., a wake-up signal, to the excitation unit. Upon receiving this signal, the signal excitation unit is instantly activated and continuously emits a specific frequency for a preset time, such as 1-5 seconds, to ensure that the human body always carries the identification signal during the user's touch interaction. In other words, the signal excitation unit is in sleep mode when the user is not touching the touch interaction device, and is only activated for a preset time when the user touches the touch interaction device, thereby avoiding the signal transmitter from being on for extended periods and saving power.

[0051] In one optional implementation of this embodiment, the identification signal is a 150kHz square wave signal.

[0052] In addition, the touch unit 20 includes a touch driver IC for separating and identifying square wave signals from the touch electrodes.

[0053] The touchscreen can be any mainstream type, such as a capacitive screen, resistive screen, or OLED touchscreen. While acquiring the touch position coordinates, the touch driver IC performs digital signal processing (DSP) on the raw sensing data on the electrodes to extract feature information at a preset frequency. Once successfully extracted, the driver IC encapsulates the identity ID (e.g., ID=1 represents the passenger seat) and coordinate data (X, Y) in the same touch data packet and reports it to the processor. This eliminates the need for additional verification by the software-level permission judgment logic, significantly reducing interaction latency and improving system response speed.

[0054] In practical applications, this touch-screen interactive control device also features anti-interference capabilities. For example, when the driver and passenger simultaneously touch the screen, the touch unit 20 senses multiple touch points, and the recognition unit 30 extracts signal features from each touch point. For instance, a touch point carrying a 150kHz signal is marked as the passenger's operation, while a touch point without a signal is marked as the driver's operation. Based on this, the touch-screen interactive control device can prioritize the driver's commands according to business priorities, or simultaneously allow both users to operate their respective UI areas within their authorized scopes, achieving true dual-view split-screen independent interaction.

[0055] Based on the foregoing embodiments, the present invention also provides a computer device, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the touch interaction control method as described above.

[0056] This invention also provides a storage medium storing a computer program, which, when executed by a processor, implements the touch interaction control method described above. Through deep collaboration between software and hardware, an efficient, safe, and low-cost operator identification solution for in-vehicle cockpits is achieved.

[0057] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not be construed as limiting the scope of protection of this application. Any technical solutions resulting from equivalent structural or procedural substitutions or modifications made based on the essential concept of this application and utilizing the content described in the text and drawings of this application, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of protection of this application.
