Detailed implementation manners

Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts fall within the scope of protection of the present application.

[0021] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. To simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present application. In addition, the present application may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0022] To solve the problem of poor interaction effect of the touch screen in the prior art, the present application provides a method, a device, a display terminal, and a storage medium for adjusting the sensitivity of a touch screen, which can improve the interaction effect of the touch screen.

[0023] See Figure 1 , Figure 1Schematic flow chart of a method for adjusting touch screen sensitivity provided by an embodiment of the present application. As Figure 1 shown, the method for adjusting touch screen sensitivity may include the following steps: Step S101: Obtain the humidity values corresponding to each position on the touch screen.

[0024] Specifically, the above touch screen may be any type of touch screen such as a resistive touch screen, a capacitive touch screen, an infrared touch screen, etc., and the embodiments of the present application do not make specific limitations. The above humidity values may be collected through devices such as humidity sensors. The humidity sensor may be a sensor device provided on the surface of the touch screen or other positions for detecting the humidity values corresponding to each position on the touch screen.

[0025] Step S102: When it is detected that there is pressure on the touch screen, compare the humidity value of the pressure area with a humidity threshold, where the pressure area is the area on the touch screen where there is pressure.

[0026] Specifically, the above humidity threshold may be set according to actual needs and is not specifically limited here. As an optional implementation manner, the humidity threshold may be obtained by measuring a large amount of water mist experimental data. The humidity threshold refers to the humidity value when the attachments on the touch screen (such as condensation formed by moisture in the air on the touch screen, or water droplets dripping onto the touch screen from other places, or oil stains or sweat and other substances contaminated from the user's fingers onto the touch screen) begin to affect the touch effect of the touch screen. If the humidity value is greater than the humidity threshold, it means that the humidity value affects the touch effect of the touch screen; if the humidity value is less than or equal to the humidity threshold, it means that the humidity value does not affect the touch effect of the touch screen. The above pressure area may refer to the area on the touch screen where there is pressure. The pressure area may be a static area or a moving area. For example, when the attachment adheres to the surface of the touch screen without moving, its pressure area is the static area where the attachment adheres; when the attachment flows on the surface of the touch screen, its pressure area is the area corresponding to the movement trajectory of the attachment.

[0027] In this step, when it is detected that there is pressure on the touch screen (this pressure may be generated by the attachments on the touch screen, may also be generated by manual touch operations, or may be jointly generated by attachments and manual touch operations), the humidity value of the pressure area can be compared with the humidity threshold. If the humidity value of the pressure area is greater than the humidity threshold, it means that the humidity on the surface of the touch screen is relatively large, and step S103 can be executed to adjust the sensitivity of the pressure area of the touch screen; if the humidity value of the pressure area is less than or equal to the humidity threshold, it means that the humidity on the surface of the touch screen is relatively small, and the touch event corresponding to the pressure area can be normally recognized and the corresponding operation can be executed without special processing.

[0028] Step S103: When the humidity value in the pressure area is greater than the humidity threshold, obtain the pressure signal of the pressure area.

[0029] Specifically, the above-mentioned pressure signal refers to the detected pressure value applied to the surface of the touch screen, and the type of this pressure signal can vary according to the type of the touch screen. For example, for a capacitive touch screen, the pressure signal can be a capacitance change value; for a resistive touch screen, the pressure signal can be a resistance change value, etc.

[0030] Step S104: Determine the pressure source type of the pressure signal according to the pressure signal, and adjust the sensitivity of the pressure area according to the pressure source type.

[0031] Specifically, the above-mentioned pressure source type can be a type where the pressure source only includes attachments (such as objects like condensation, water droplets, oil stains, sweat, etc. attached to the touch screen), or a type where the pressure source includes attachments and human touch operations (such as a user's click operation, press operation, etc.), or a type that only includes human touch operations, etc. Since different pressure source types have different requirements for the sensitivity of the touch screen, the sensitivity of the pressure area can be adjusted according to the pressure source type.

[0032] In this embodiment, the humidity values corresponding to each position on the touch screen can be detected. When the humidity value in the pressure area of the touch screen is greater than the humidity threshold, it can be determined that there is pressure on the touch screen and the touch screen is in a humid environment. At this time, the pressure source type of the pressure signal in the pressure area can be further determined, and the sensitivity of the pressure area can be automatically adjusted according to the pressure source type, thereby reducing the interference of attachments on human touch operations and improving the interaction effect of the touch screen.

[0033] In an alternative embodiment, the above-mentioned step S104: Determine the pressure source type of the pressure signal according to the pressure signal, includes: Compare the pressure signal with a preset first pressure threshold and a second pressure threshold respectively, where the second pressure threshold is greater than the first pressure threshold; When the pressure signal is greater than or equal to the first pressure threshold and less than the second pressure threshold, determine that the pressure source type is the first type where the pressure source only includes attachments; When the pressure signal is greater than or equal to the second pressure threshold, determine that the pressure source type is the second type where the pressure source includes attachments and human touch operations.

[0034] Specifically, the above first pressure threshold and second pressure threshold can be set according to actual needs, and no specific limitation is made here. As an optional implementation manner, the first pressure threshold and the second pressure threshold can be obtained by measuring a large amount of experimental data. The first pressure threshold refers to the pressure value when the attachment starts to be detected with a pressure signal on the touch screen. The second pressure threshold refers to the pressure value when a human touch operation starts to be detected with a pressure signal on the touch screen.

[0035] When determining the type of the pressure source of the pressure signal based on the pressure signal, the pressure signal can be first compared with the preset first pressure threshold and second pressure threshold respectively. If the pressure signal is greater than or equal to the first pressure threshold and less than the second pressure threshold, it can be determined that the type of the pressure source is the first type only including the attachment, that is, the pressure on the touch screen is generated by the attachment on the touch screen. For example, when there are attachments such as water droplets, condensation, oil stains or sweat on the surface of the touch screen, a small pressure will be generated on the touch screen due to the attachment. If the pressure signal is greater than or equal to the second pressure threshold, it can be determined that the type of the pressure source is the second type including the attachment and the human touch operation, that is, the pressure on the touch screen is jointly generated by the attachment and the human touch operation on the touch screen. For example, when a user touches a touch screen with an attachment on its surface with a dry finger, or when a user touches a dry touch screen with a finger with water, oil stains or sweat, or when a user touches a touch screen with an attachment on its surface with a finger with water, oil stains or sweat, a large pressure will be generated on the touch screen due to the finger touch and the attachment.

[0036] In this way, the type of the pressure source of the pressure signal can be accurately determined according to the magnitude of the pressure signal, which is convenient for accurately adjusting the sensitivity of the pressure area based on the type of the pressure source subsequently, thereby improving the interaction effect of the touch screen.

[0037] In an optional embodiment, the above step S104, adjusting the sensitivity of the pressure area according to the type of the pressure source, includes: In the case where the type of the pressure source is the first type, reducing the sensitivity of the pressure area and restoring the sensitivity of the pressure area when the attachment disappears; In the case where the type of the pressure source is the second type, increasing the sensitivity of the pressure area and reducing the sensitivity of the pressure area when the human touch operation stops.

[0038] Specifically, when adjusting the sensitivity of the pressure area according to the type of pressure source, if the pressure source type is the first type, the sensitivity of the pressure area can be reduced to reduce the misoperation caused by the attachment, and when the attachment disappears, the sensitivity of the pressure area can be restored. If the pressure source type is the second type, the sensitivity of the pressure area can be increased to improve the sensitivity of detecting human touch operations, reduce the interference of the attachment on human touch operations, and when the human touch operation stops, the sensitivity of the pressure area can be reduced to reduce the misoperation caused by the attachment.

[0039] In this way, the sensitivity of the pressure area can be automatically adjusted according to the type of pressure source, thereby reducing the interference of the attachment on human touch operations and improving the interaction effect of the touch screen.

[0040] In an alternative embodiment, the above steps of reducing or increasing the sensitivity of the pressure area include: Inputting the humidity value, pressure signal, first pressure threshold, second pressure threshold, and the duration of the pressure signal of the pressure area into a pre-trained sensitivity recognition model to output a predicted sensitivity, and adjusting the sensitivity of the pressure area from the current sensitivity to the predicted sensitivity.

[0041] Specifically, the humidity value, pressure signal, first pressure threshold, second pressure threshold, and the duration of the pressure signal of the pressure area can be input into a pre-trained sensitivity recognition model to output a predicted sensitivity, and the sensitivity of the pressure area can be adjusted from the current sensitivity to the predicted sensitivity, thereby realizing the adjustment of the sensitivity of the pressure area.

[0042] It should be noted that the sensitivity recognition model is trained based on multiple training samples. Each training sample includes multiple sensitivity influence parameters and sensitivity labels corresponding to the multiple sensitivity influence parameters. The multiple sensitivity influence parameters include the humidity value on the touch screen, the pressure threshold corresponding to the attachment on the touch screen, the pressure value of the attachment on the touch screen, the pressure value of the manual touch operation, the pressure threshold corresponding to the manual touch operation, and the duration of the manual touch operation. When training the sensitivity recognition model, training samples containing the humidity value (H) on the touch screen, the pressure threshold (Cd) corresponding to the attachment on the touch screen, the pressure value (Pd) of the attachment on the touch screen, the pressure value (Pf) of the manual touch operation, the pressure threshold (Cf) corresponding to the manual touch operation, and the duration (T) of the manual touch operation, as well as the sensitivity labels corresponding to each training sample, can be collected. Then, the parameters in all training samples are normalized to the same range, such as the range interval of [0, 1], to avoid the influence of dimensional differences on model training. Next, the training samples are input into the model to be trained for training until the loss value between the sensitivity output by the model and the input sensitivity label tends to be stable, and the sensitivity recognition model is obtained. The relationship between the parameters in the training samples can be expressed by the following formula: S = W0 + W1×H + W2×Cd + W3×Pd + W4×Pf + W5×Cf + W6×T; Where: S represents the sensitivity output by the model, H represents the humidity value on the touch screen, Cd represents the pressure threshold corresponding to the attachment on the touch screen, Pd represents the pressure value of the attachment on the touch screen, Pf represents the pressure value of the manual touch operation, Cf represents the pressure threshold corresponding to the manual touch operation, T represents the duration of the manual touch operation, W1, W2, W3, W4, W5, and W6 are weight coefficients that need to be determined through training data, and these coefficients represent the influence degree of each input parameter on the sensitivity S. W0 is a constant term used to adjust the baseline sensitivity of the model.

[0043] In this way, the sensitivity recognition model can be used to accurately recognize the sensitivity required by the touch screen currently, and realize the automatic adjustment of the sensitivity of the pressure area.

[0044] In an optional embodiment, the method of adjusting the sensitivity of the pressure area from the current sensitivity to the predicted sensitivity in the above steps includes at least one of the following: Adjust the first pressure threshold and the second pressure threshold; Adjust the interference filtering coefficient of the sensitivity recognition model; Adjust the sampling rate of the pressure signal.

[0045] Specifically, when adjusting the sensitivity, it can be achieved by one or a combination of the following methods: adjusting the first pressure threshold and the second pressure threshold, adjusting the interference filtering coefficient of the sensitivity recognition model, adjusting the sampling rate of the pressure signal, etc. For example, when it is necessary to reduce the sensitivity, it can be achieved by increasing the first pressure threshold, increasing the second pressure threshold, increasing the interference filtering coefficient of the sensitivity recognition model, reducing the sampling rate of the pressure signal, etc.; when it is necessary to increase the sensitivity, it can be achieved by decreasing the first pressure threshold, decreasing the second pressure threshold, decreasing the interference filtering coefficient of the sensitivity recognition model, increasing the sampling rate of the pressure signal, etc. In this way, the sensitivity of the pressure area can be adjusted by the above methods.

[0046] It should be noted that increasing the first pressure threshold and the second pressure threshold will increase the threshold value when the touch screen detects pressure, thus reducing the sensitivity of the touch screen. Decreasing the first pressure threshold and the second pressure threshold will decrease the threshold value when the touch screen detects pressure, thus increasing the sensitivity of the touch screen. Increasing the interference filtering coefficient of the sensitivity recognition model will significantly reduce noise, but may over-smooth the signal, resulting in the filtering out of weak real pressure changes (such as light touches), thereby reducing the sensitivity of the touch screen. Decreasing the interference filtering coefficient of the sensitivity recognition model will retain more high-frequency signal details, thereby increasing the sensitivity of the touch screen. Reducing the sampling rate of the pressure signal will reduce the probability of detecting small pressure changes or rapid touch actions, thereby reducing the sensitivity of the touch screen. Increasing the sampling rate of the pressure signal will increase the probability of detecting small pressure changes or rapid touch actions, thereby increasing the sensitivity of the touch screen.

[0047] In an alternative embodiment, the method further includes: When the pressure source type is the second type, identifying the touch event corresponding to the pressure area and performing a response operation, where the touch event is a click event or a swipe event.

[0048] Specifically, when the pressure source type is the first type, it means that the pressure on the touch screen is generated by the attachment, and there is no real human touch operation at this time, so there is no need to respond to the touch event corresponding to the pressure area. When the pressure source type is the second type, it means that the pressure on the touch screen is generated by the attachment and human touch operation together. At this time, it is necessary to identify the touch event corresponding to the pressure area and perform a response operation to achieve the human-computer interaction function of the touch screen. In an alternative embodiment, after the above step S102 of comparing the humidity value of the pressure area with the humidity threshold, the method further includes: When the humidity value of the pressure area is less than or equal to the humidity threshold, identifying the touch event corresponding to the pressure area and performing a response operation, where the touch event is a click event or a swipe event.

[0049] Specifically, when the humidity value in the pressure area is less than or equal to the humidity threshold, it indicates that the humidity value on the surface of the touch screen is small and will not interfere with the artificial touch operation. At this time, the touch event corresponding to the pressure area can be recognized and the response operation can be executed to realize the human-computer interaction function of the touch screen.

[0050] In an optional embodiment, the touch screen sensitivity adjustment process provided by the embodiments of the present application is as Figure 2 shown, and it may include the following steps: Step S201, detect the humidity value on the surface of the touch screen.

[0051] Among them, the touch screen has a humidity detection function and can detect the humidity value at each position of the touch screen to judge the area of the attachment. In addition, the touch screen also has a pressure detection function and can detect the touch pressure. The touch screen can be connected to the main control chip of the display terminal through a signal line, and can transmit the humidity information and pressure information of the touch screen to the main chip for decision-making.

[0052] Step S202, judge whether there is pressure on the surface of the touch screen and the humidity value exceeds the humidity threshold.

[0053] Among them, the humidity threshold can be determined through a large amount of water mist experiment data. When it is detected that there is pressure on the surface of the touch screen and the humidity value exceeds the humidity threshold, it can be determined that there is an attachment on the surface of the touch screen, and step S203 is executed; when it is detected that there is no pressure on the surface of the touch screen or the humidity value does not exceed the humidity threshold, it can be determined that there is no attachment on the surface of the touch screen, and step S207 is executed.

[0054] Step S203, transmit the humidity information and pressure information to the main chip, and make a judgment in combination with the sensitivity recognition model.

[0055] Among them, through a large amount of experimental data of the touch screen with attachments and accompanied by real finger operations, the sensitivity recognition model GreeTouchModel can be trained by adjusting different touch sensitivities to achieve touch accuracy.

[0056] Step S204, judge whether there is an artificial touch operation in the humidity area.

[0057] Step S205, increase the sensitivity of the pressure area and decrease the sensitivity of the pressure area when the artificial touch operation stops.

[0058] When there is an attachment on the touch screen surface and a human makes a real touch on the touch screen, the main control chip combines humidity information and pressure information to determine that there is a human touch operation on the touch screen, improves the sensitivity of the pressure area, avoids interference from the attachment, and correctly responds to the human touch operation to ensure user interaction requirements. Moreover, after the human touch operation disappears, the sensitivity of this area decreases to prevent accidental touches; the sensitivity of the remaining humidity areas remains low to prevent accidental touches.

[0059] Step S206: Reduce the sensitivity of the pressure area and, in the case where the attachment disappears, restore the sensitivity of the pressure area.

[0060] When the attachment is stationary on the touch screen, it will exert a certain pressure on the touch screen. The main control chip determines whether the humidity value of the pressure area is greater than the humidity threshold. If the humidity value of the pressure area is greater than the humidity threshold, it is determined that there is an attachment at this position; then the pressure signal is respectively compared with a preset first pressure threshold and a second pressure threshold. If the pressure signal is greater than or equal to the first pressure threshold and less than the second pressure threshold, it is determined as a non-human touch operation (i.e., the first type only including the attachment). At this time, the sensitivity of this area can be reduced to further avoid accidental touches and restored when the attachment disappears.

[0061] When the attachment is flowing on the touch screen, it will exert a certain pressure on the touch screen and there is a pressure movement trajectory. The main control chip determines whether the humidity value of the pressure area is greater than the humidity threshold. If the humidity value of the pressure area is greater than the humidity threshold, it is determined that there is an attachment at this position; then the pressure signal is respectively compared with a preset first pressure threshold and a second pressure threshold. If the pressure signal is greater than or equal to the second pressure threshold, it is determined that there is a human touch operation. At this time, the sensitivity of this area can be reduced to further avoid accidental touches and restored when the attachment disappears.

[0062] Step S207: Without an attachment, process the human touch operation normally.

[0063] When it is detected that the humidity value on the touch screen surface does not exceed the humidity threshold, the touch screen does not need to report the humidity information and the pressure signal to the main control chip, but only needs to report the touch coordinates. The main control chip processes the human touch operation normally based on the touch coordinates to achieve human-computer interaction.
