Description

Technical Field

[0001] This invention relates to the field of touch button calibration technology, and in particular to a touch button calibration method, system, device and medium. Background Technology

[0002] With the development of automotive electronics and interior design, physical buttons in cars are becoming fewer and fewer, while touch buttons are becoming more and more common. These touch buttons are increasingly favored by designers and consumers due to their advantages such as no mechanical travel, no abnormal noise, and the ability to be shaped freely.

[0003] The principle of touch buttons is as follows: a self-capacitive touch film (sensor) is silkscreened on the back of the cover plate of the area to be touched. Electrical signals are connected to the I / O port of the PSOC chip via an FPC cable. The chip detects changes in the capacitance of the I / O port and, combined with appropriate software logic, determines whether the touch switch has been pressed and outputs the corresponding signal. Regarding button calibration, traditional mechanical buttons quantify finger touch actions through the travel of the mechanical device, using physical data such as length and pressure to calibrate the button action. Current technology only tests whether a touch is effective; it does not calibrate the touch buttons, nor does it differentiate between adult and child calibration. Therefore, a touch button calibration method, system, device, and medium are needed. Summary of the Invention

[0004] This application provides a touch button calibration method, system, device, and medium, which at least partially solves the technical problems in the prior art that touch buttons cannot be calibrated like traditional mechanical buttons and cannot be calibrated for different groups of people, and achieves the technical effect of calibrating touch buttons to distinguish between adults and children.

[0009] Step S103: Verify all the above feedback signals according to the minimum value. If the first preset condition is met, it indicates that the touch button is normal; otherwise, repeat steps S101 to S103.

[0010] Step S104: Select a capacitive pen with a diameter smaller than the preset diameter and obtain the feedback signal value corresponding to the capacitive pen; if the feedback signal value and the minimum value meet the preset second preset condition, then the calibration requirements are met.

[0023] Optionally, after the calibration requirements are met, the above method may also include:

[0024] Multiple testers were selected to test the touch buttons using their fingers. If the first preset condition was met, it indicated that the touch buttons were working properly.

[0025] Optionally, the above step of selecting a capacitive pen with a preset diameter further includes:

[0029] The adult finger testing module is used to select a capacitive pen of a preset diameter and obtain the minimum value of the effective touch of the feedback signal corresponding to the capacitive pen.

[0030] The adult finger calibration module is used to verify all the above feedback signals according to the minimum value. If the first preset condition is met, it indicates that the touch button is normal; otherwise, repeat steps S101 to S103.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0046] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0047] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0048] It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solutions of this application, rather than limitations on the technical solutions of this application. Unless otherwise specified, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

[0049] This application provides a touch button calibration method, system, device, and medium, which improves upon the technical problems in the prior art where touch buttons cannot be calibrated like traditional mechanical buttons and cannot be calibrated for different groups of people, thus achieving the technical effect of calibrating touch buttons to distinguish between adults and children.

[0050] The technical solution of this application embodiment is to solve the above-mentioned technical problems, and the general idea is as follows:

[0051] Using multiple capacitive pens of different diameters to simulate people of different ages, the touch buttons on the touch screen were tested with different pressures. The sensitivity threshold and hysteresis parameters were calculated based on the magnitude of the acquired signal values. The smallest effective value was selected for calibration, so that people of the preset age group could successfully trigger the button, that is, adults could successfully trigger the button, but children could not trigger it. This not only completed the calibration, but also improved the safety of the touch button.

[0052] In the embodiments of this application, the following are provided: Figure 1 The method shown includes steps S101 to S104:

[0053] Step S101: Use multiple capacitive pens of different diameters to test the touch buttons on the touch screen with different pressures, and acquire the feedback signals of the touch screen in real time.

[0054] It should be noted that multiple capacitive styluses of different diameters were used for testing to simulate finger sizes at different ages; and the varying pressure applied was used to test the effective value of the triggered signal. Furthermore, the feedback signal from the touchscreen was acquired in real time using a PSOC chip, which identifies changes in the capacitance of the I / O ports to determine whether the touch switch was pressed. The schematic diagram is shown below. Figure 2 As shown.

[0055] Step S102: Select a capacitive pen with a preset diameter and obtain the minimum value of the effective touch of the feedback signal corresponding to the capacitive pen.

[0056] It should be noted that the preset diameter of the capacitive stylus is determined based on the size of an adult's finger. The minimum value required for a valid touch to obtain a feedback signal is, for example... Figure 3 As shown, the design aims to obtain the minimum signal value required for an adult to touch the button, thus making it easier for adults to trigger the touch button and improving the sensitivity of the touch interface for adults.

[0057] Step S103: Verify all the above feedback signals according to the minimum value. If the first preset condition is met, it indicates that the touch button is normal; otherwise, repeat steps S101 to S103.

[0058] It should be noted that verification is performed on all feedback signals, meaning all signal values ​​are greater than the aforementioned minimum value. Specifically, this is measured using the minimum sensitivity threshold (FT) and hysteresis parameter (HY), meaning all feedback signal values ​​are greater than the sum of FT and HY. The comparison results are as follows: Figure 4 As shown, the wave represents the signal value, and the straight line represents the sum of FT and HY.

[0059] Step S104: Select a capacitive pen with a diameter smaller than the preset diameter and obtain the feedback signal value corresponding to the capacitive pen; if the feedback signal value and the minimum value meet the preset second preset condition, then the calibration requirements are met.

[0060] It should be noted that the capacitive pen, with a diameter smaller than the preset size, is designed to simulate the size of a child's finger. This means all signal values ​​are greater than the minimum effective touch threshold, measured by the minimum sensitivity threshold (FT) and hysteresis parameter (HY). Specifically, all feedback signal values ​​are less than the sum of FT and HY. The comparison results are as follows: Figure 5 As shown, the wave represents the signal value, and the straight line represents the sum of FT and HY.

[0061] Furthermore, the step of verifying all the above feedback signals based on the minimum value also includes: calculating a sensitivity threshold and a hysteresis parameter based on the minimum value; and verifying all the above feedback signals based on the sensitivity threshold and the hysteresis parameter.

[0062] It should be noted that the sensitivity threshold (FT) and hysteresis parameter (HY) are calculated relative to the minimum effective touch value as follows: FT is 80% of the minimum effective touch value; HY is 10% of FT. The actual measured data are shown in the table below:

[0063]

[0064] Furthermore, the above method also includes:

[0065] Using a capacitive stylus of the same diameter and with the same preset force, the touch buttons of multiple touch screens are tested; when the sensitivity threshold and hysteresis parameter of the effective touch value obtained by the test both meet the first preset condition and the second preset condition, it is determined that the calibration requirements are met.

[0066] It should be noted that the above method is for calibrating a single product. However, for different products, consistent button calibration is required to ensure product consistency. Therefore, capacitive styluses of the same diameter are used to test the touch buttons on multiple touchscreens using the same preset pressure. The test criteria are as follows: the capacitive stylus representing the diameter of an adult's finger meets the first preset condition, i.e., all feedback signal values ​​are greater than the sum of FT and HY in the effective touch values. The capacitive stylus representing the diameter of a child's finger meets the second preset condition, i.e., all feedback signal values ​​are less than the sum of FT and HY in the effective touch values.

[0067] Furthermore, the above method also includes:

[0068] The touchscreen is stored at a preset temperature for a preset time.

[0069] Multiple capacitive pens of different diameters were used to test the touch buttons on the touch screen based on different pressures.

[0070] When the sensitivity threshold and hysteresis parameters of the effective touch value obtained by the test both meet the first preset condition and the second preset condition, it is determined that the calibration requirements are met.

[0071] It should be noted that storing the touchscreen at a preset temperature for a preset time is intended to calibrate the robustness of the touch buttons; that is, the product can correctly detect adult finger touch actions when placed at the required highest and lowest operating temperatures, using the same button on the same display, and at operating temperatures of +80℃ and -30℃ for 4 hours. The judgment conditions remain the same as those mentioned above. The specific method is as follows: After being stored at a temperature of -30±5℃ for 4 hours, it was removed and tested. Using an 8mm capacitive stylus and a finger, the touch press and release states were correctly recognized; however, the 5mm stylus did not trigger false triggers. After being stored at a temperature of 80±5℃ for 4 hours, it was removed and tested. Using an 8mm capacitive stylus and a finger, the software could correctly recognize the touch press and release states; however, the 5mm stylus did not trigger false triggers.

[0072] Furthermore, the above methods also include;

[0073] When the above-mentioned touch button is a slider button, the calibration value is selected as the one with the smallest sensitivity threshold among all the above-mentioned slider buttons.

[0074] It should be noted that because the sensitivity threshold (FT) of the slider buttons cannot be set individually, the minimum sensitivity threshold among all slider buttons is directly taken to ensure that all of them can be detected correctly. The test results are as follows:

[0075]

[0076] The final sensitivity threshold (FT) is 85. The corresponding hysteresis parameter (HY) is 9.

[0077] Furthermore, after the calibration requirements are met, the above method also includes:

[0078] Multiple testers were selected to test the touch buttons using their fingers. If the first preset condition was met, it indicated that the touch buttons were working properly.

[0079] It should be noted that while a capacitive stylus can largely simulate a human finger for a touchscreen, there are still some differences between a capacitive stylus and a human finger. To avoid interference from unknown factors, multiple testers used their fingers to test the aforementioned touch buttons, thereby conducting actual working condition tests and improving the accuracy of the calibration.

[0080] Furthermore, the above-mentioned step of selecting a capacitive pen with a preset diameter also includes:

[0081] The preset diameter of the capacitive pen is determined based on the size of an adult's finger.

[0082] It should be noted that in this embodiment, the preset diameter is simulated by an 8mm diameter capacitive pen to represent an adult's finger, while a 5mm diameter capacitive pen is used to represent a child.

[0083] Based on the same inventive concept, embodiments of this application provide a touch button calibration system, such as... Figure 6 As shown, it includes:

[0084] The data acquisition module 201 is used to test the touch buttons on the touch screen using multiple capacitive pens of different diameters based on different pressures, and to acquire the feedback signals of the touch screen in real time.

[0085] The adult finger testing module 202 is used to select a capacitive pen with a preset diameter and obtain the minimum value of the effective touch of the feedback signal corresponding to the capacitive pen.

[0086] The adult finger calibration module 203 is used to verify all the above feedback signals according to the above minimum value. If the first preset condition is met, it indicates that the touch button is normal; otherwise, steps S101 to S103 are repeated.

[0087] The child hand calibration module 204 is used to select a capacitive pen with a diameter smaller than the preset diameter and obtain the feedback signal value corresponding to the capacitive pen; if the feedback signal value and the minimum value meet the preset second preset condition, then the calibration requirements are met.
