Description

Technical Field

[0001] The present invention relates to the technical field of smart wearable devices, and in particular to a water mist stabilization method and device suitable for a capacitive touch screen of a smart wearable device. Background Art

[0002] When exploring the environmental challenges faced by smart watches equipped with capacitive touch screens, we have to pay attention to their performance under certain external conditions. In particular, when smart watches are exposed to direct contact with rain, rapid temperature changes indoors and outdoors, or inadvertent liquid splashes in daily life, the surface of the smart watch's precise capacitive touch screen is prone to forming a thin layer of water mist or a small amount of fine water droplets. This phenomenon, such as Figure 1 As can be seen intuitively, not only does it reduce the screen clarity, but it also significantly interferes with the normal operation of the touch system.

[0003] Specifically, capacitive touch technology relies on the change of the weak electric field formed between human skin and the screen to identify touch actions. However, when water mist covers or water droplets adhere to the screen, they, as conductive media, will mistakenly participate in this electric field interaction process, causing the touch data value to rise abnormally, which is the so-called "touch data value drift". This change directly affects the accuracy and response speed of the touch system.

[0004] Further observation, such as Figure 2 and Figure 3 As shown in the figure, when the user tries to operate the watch screen by sliding his finger in such an environment, the originally evenly distributed water mist will be forced to gather due to the movement of the finger, and gradually condense into larger water droplets. This process not only aggravates the distortion of touch data, but also makes the recognition of touch points extremely unstable. Specifically, the random distribution and dynamic changes of water droplets cause the position of the touch screen to shift frequently, which cannot accurately reflect the user's true intention. Figure 6a This offset effect is particularly evident in scenes with

[0005] It should be noted that in Figure 1-Figure 3 In the figure, the red positive area represents the normal "handliness value" generated by direct contact of the user's finger, while the blue negative area reveals the abnormal "water value" caused by the intervention of water medium. The sharp contrast between the two intuitively demonstrates the serious impact of water mist and water droplets on touch accuracy.

[0006] In summary, when a smartwatch equipped with a capacitive touch screen encounters the above-mentioned environmental challenges, its touch performance will be significantly reduced, which will not only affect the user experience, but may also interfere with the normal function execution of the watch. Summary of the invention

[0007] In view of the technical defects pointed out in the background technology, the purpose of the embodiments of the present invention is to provide a water mist stabilization method and device suitable for a capacitive touch screen of a smart wearable device.

[0008] To achieve the above objectives, in a first aspect, an embodiment of the present invention provides a water mist stabilization method applicable to a capacitive touch screen of a smart wearable device, comprising:

[0009] When a stroke action is detected on the capacitive touch screen of the smart wearable device, three consecutive frames of data are extracted for each touch point forming the stroke action; there are a small amount of water droplets on the capacitive touch screen or it is covered with water mist;

[0010] Perform dynamic weighted calculation based on three consecutive frames of data to obtain the coordinate value of each touch point;

[0011] Connect the coordinate values ​​of multiple touch points to form a new line trajectory.

[0012] As a preferred implementation of the present application, before a stroke action is detected on the capacitive touch screen of the smart wearable device, the water mist stabilization method further includes:

[0013] Monitoring the capacitive touch screen to obtain touch actions;

[0014] It is determined whether the touch action is a stroke action.

[0015] As a specific implementation of the present application, a dynamic weighted calculation is performed based on three consecutive frames of data to obtain the coordinate value of each touch point, specifically:

[0016] If three consecutive frames of data are F1, F2 and F3, take the maximum value D1 of F2;

[0017] A nine-square grid is formed around the maximum value D1, and the corresponding values ​​are F2D1~F2D9;

[0018] Sixteen squares are formed outside the nine squares, and the corresponding values ​​are F2U1 to F2U16 respectively;

[0019] For F1 and F3 frames, nine-grid and sixteen-grid are formed with the maximum value D1 as the center, and the corresponding values ​​are F1D1~F1D9, F3D1~F3D9, F1U1~F1U16, F3U1~F3U16 respectively;

[0020] The minimum negative value data in the sixteen squares of the F2 frame is selected as the maximum water property value of the F2 frame, which is recorded as F2M;

[0021] Calculate the final touch-pressed nine-grid value based on the nine-grid data and sixteen-grid data of the F1, F2, and F3 frames ;

[0022] Using the coordinate calculation method, according to the nine-square grid value The coordinate value of each touch point can be obtained.

[0023] As a preferred implementation of the present application, after forming a new scribing track, the water mist stabilization method further includes:

[0024] Obtaining the line drawing trajectory before stabilization; the line drawing trajectory before stabilization is calculated using a coordinate calculation method;

[0025] Compare the stroke trajectory before stabilization with the new stroke trajectory.

[0026] In a second aspect, the embodiment of the present application further provides a water mist stabilization device suitable for a capacitive touch screen of a smart wearable device, comprising:

[0027] A data extraction unit is used to extract three consecutive frames of data for each touch point that forms the stroke action after monitoring a stroke action on the capacitive touch screen of the smart wearable device; the capacitive touch screen has a small amount of water droplets or is covered with water mist;

[0028] A coordinate calculation unit, used to perform dynamic weighted calculation based on three consecutive frames of data to obtain the coordinate value of each touch point;

[0029] The trajectory generation unit is used to connect the coordinate values ​​of multiple touch points to form a new stroke trajectory.

[0030] Furthermore, as a preferred implementation of the present application, the water mist stabilization device further includes:

[0031] The monitoring unit is used to monitor the capacitive touch screen of the smart wearable device before monitoring that the capacitive touch screen has a stroke action, obtain the touch action, and determine whether the touch action is a stroke action.

[0032] In the third aspect, an embodiment of the present invention also provides another water mist stabilization device suitable for a capacitive touch screen of a smart wearable device, comprising a processor, an input device, an output device and a memory, wherein the processor, input device, output device and memory are interconnected, wherein the memory is used to store a computer program, and the computer program includes program instructions, and the processor is configured to call the program instructions to execute the method of the first aspect above.

[0033] Compared with the prior art, when there are a small amount of water droplets or a certain amount of water mist on the capacitive touch screen of a smart wearable device (such as a watch), the water mist stabilization solution for the capacitive touch screen provided by the embodiment of the present invention has the following advantages:

[0034] 1. The front, middle and back three frames of data are used to perform dynamic weighted coordinate calculation on the capacitive screen data of the smart watch with water mist. Compared with the direct coordinate calculation method, it can effectively suppress the situation where the center of gravity algorithm becomes unstable due to water mist.

[0035] 2. Improve user experience: As a commonly used smart device in daily life, the clarity and sensitivity of the touch screen of smart watches are directly related to the user experience. The adhesion of water mist and water droplets on the screen will cause problems such as rising touch data values, distortion of touch values, and displacement of the touch screen reporting point, making it impossible for users to operate the watch normally, seriously affecting the user experience. Therefore, solving this problem can ensure that users can use smart watches smoothly and accurately in various environments, improving overall satisfaction.

[0036] 3. Enhanced durability of watches: Smart watches are usually exposed to complex and changing environments, such as rain, temperature differences between indoors and outdoors, and liquid splashes. Traditional capacitive touch screens are easily disturbed in these environments, resulting in performance degradation or even damage. By developing touch screen technology that effectively resists interference from water mist and water droplets, the durability of watches can be significantly enhanced, their service life can be extended, and the cost of repairs and replacements caused by environmental factors can be reduced.

[0037] 4. Expandable application areas: With the continuous development of smart watch technology, its application areas are also expanding. In addition to daily personal wear, smart watches are also widely used in medical, sports, outdoor adventure and other fields. In these fields, users often need to face more severe environmental conditions. Touch screen technology that can effectively resist the interference of water mist and water droplets will enable smart watches to better adapt to these application scenarios and provide users with more stable and reliable services.

Compared with the direct coordinate calculation method, it can effectively suppress the situation where the coordinate calculation method becomes unstable due to water mist.

[0089] 2. Improve user experience: As a commonly used smart device in daily life, the clarity and sensitivity of the touch screen of smart watches are directly related to the user experience. The adhesion of water mist and water droplets on the screen will cause problems such as rising touch data values, distortion of touch values, and displacement of the touch screen reporting point, making it impossible for users to operate the watch normally, seriously affecting the user experience. Therefore, solving this problem can ensure that users can use smart watches smoothly and accurately in various environments, improving overall satisfaction.

[0090] 3. Enhanced durability of watches: Smart watches are usually exposed to complex and changing environments, such as rain, temperature differences between indoors and outdoors, and liquid splashes. Traditional capacitive touch screens are easily disturbed in these environments, resulting in performance degradation or even damage. By developing touch screen technology that effectively resists interference from water mist and water droplets, the durability of watches can be significantly enhanced, their service life can be extended, and the cost of repairs and replacements caused by environmental factors can be reduced.

[0091] 4. Expandable application areas: With the continuous development of smart watch technology, its application areas are also expanding. In addition to daily personal wear, smart watches are also widely used in medical, sports, outdoor adventure and other fields. In these fields, users often need to face more severe environmental conditions. Touch screen technology that can effectively resist the interference of water mist and water droplets will enable smart watches to better adapt to these application scenarios and provide users with more stable and reliable services.

[0100] Sixteen squares are formed outside the nine squares, and the corresponding values ​​are F2U1 to F2U16 respectively;

[0101] For F1 and F3 frames, nine-grid and sixteen-grid are formed with the maximum value D1 as the center, and the corresponding values ​​are F1D1~F1D9, F3D1~F3D9, F1U1~F1U16, F3U1~F3U16 respectively;
