Once water droplets adhere to the mirror surface, the user must manually activate the defogger function or use voice commands, rather than intelligently activating the defogger function, resulting in a poor user experience.

[0035] In the subsequent description, suffixes such as "module," "component," or "unit" used to represent elements are only used to facilitate the description of the present invention and have no specific meaning. Therefore, "module," "component," or "unit" can be used interchangeably.

[0036] Example 1

[0037] Please refer to Figure 1FIG2 is a flow chart of a mirror surface water mist detection method provided by an embodiment of the present invention. This embodiment provides a mirror surface water mist detection method, which includes:

[0038] S1, acquiring touch monitoring data through the capacitive screen on the mirror surface;

[0039] S2. When the touch monitoring data satisfies a preset touch displacement condition, determining that water mist exists on the mirror surface, wherein the touch displacement condition includes a preset touch area threshold and a preset sliding displacement threshold.

[0040] In this embodiment, touch monitoring data is acquired via a capacitive screen on the mirror surface. The smart mirror includes a mirror surface and one or more capacitive screens on the mirror surface. In this embodiment, touch signals from attached objects are acquired via the capacitive screen as touch monitoring data.

[0041] In this embodiment, when there is water mist on the mirror surface, water droplets, as attachments to the capacitive screen, will generate certain touch signals on the capacitive screen. At this time, by performing a corresponding touch range judgment on the touch monitoring data, it can be determined whether there are water droplets attached to the mirror surface of the smart mirror. Furthermore, by performing a corresponding displacement judgment on the displacement of the water droplet touch area, the degree of water droplets on the mirror surface can be determined.

[0042] This embodiment provides the beneficial effect of acquiring touch monitoring data via the capacitive screen on the mirror surface; determining the presence of water mist on the mirror surface when the touch monitoring data meets preset touch displacement conditions, wherein the touch displacement conditions include a preset touch area threshold and a preset sliding displacement threshold. This provides a user-friendly mirror water mist detection solution, improving the automation level of smart mirror products and enhancing the user experience without increasing costs through efficient and accurate water mist detection logic.

[0043] Example 2

[0044] Based on the above-mentioned first embodiment, in order to improve the accuracy of detecting water mist based on the mirror touch signal, in this embodiment, when the touch monitoring data meets the preset touch displacement condition, before determining that water mist exists on the mirror, the following steps are included:

[0045] A first touch area threshold corresponding to the cross-sectional area of ​​a water droplet and a second touch area threshold corresponding to the area of ​​a finger pad are preset, wherein the first touch area threshold is smaller than the second touch area threshold.

[0046] In this embodiment, to improve the accuracy of water droplet recognition, a solution for setting the cross-sectional area of ​​a water droplet based on the area of ​​the finger pad is proposed. Specifically, a first touch area threshold corresponding to the cross-sectional area of ​​the water droplet and a second touch area threshold corresponding to the area of ​​the finger pad are preset. The first touch area threshold is smaller than the second touch area threshold. The finger pad area can be the area of ​​any of the user's five fingers.

[0047] In this embodiment, when the touch monitoring data satisfies a preset touch displacement condition, determining that water mist exists on the mirror surface includes:

[0048] When the touch area of ​​the touch monitoring data is larger than the first touch area and smaller than the second touch area, a touch object of the touch area is generated as an attachment.

[0049] In this embodiment, in order to improve the applicability of water droplet recognition, when the touch area of ​​the touch monitoring data is larger than the first touch area and smaller than the second touch area, the touch object generating the touch area is used as an attachment, thereby effectively avoiding the misrecognition of water droplets.

[0050] Figure 2 This is a second flow chart of a mirror water mist detection method provided by an embodiment of the present invention. In this embodiment, when the touch monitoring data meets a preset touch displacement condition, it is determined that water mist exists on the mirror surface, and further includes:

[0051] S21, detecting the sliding displacement of the attached object within a preset time interval for generating the touch area;

[0052] S22: When the sliding displacement is greater than the sliding displacement threshold, determine that there is a water drop on the mirror surface.

[0053] In this embodiment, taking into account the fluidity of water droplets, the sliding displacement of attached objects is used as a detection target to further determine whether water droplets are present. Specifically, the sliding displacement of the attached object is first detected within a preset time interval for generating the touch area. The preset time interval is determined based on the current humidity. For example, the higher the humidity, the shorter the time interval, thereby improving the accuracy of the detection result. Then, when the sliding displacement exceeds a sliding displacement threshold, the presence of water droplets on the mirror surface is determined. The sliding displacement threshold is determined based on the current humidity. For example, the higher the humidity, the larger the sliding displacement threshold, thereby further improving the accuracy of the detection result.

[0054] Figure 3This is the third flow chart of a mirror water mist detection method provided by an embodiment of the present invention. In this embodiment, before acquiring touch monitoring data through the capacitive screen on the mirror surface, the method includes:

[0055] S01, presetting a first humidity threshold;

[0056] S02. Get the current humidity of the space.

[0057] Figure 4 This is a fourth flow chart of a mirror surface water mist detection method provided by an embodiment of the present invention. In this embodiment, when the touch monitoring data meets a preset touch displacement condition, determining that water mist exists on the mirror surface includes:

[0058] S23, when the humidity of the space is greater than the first humidity threshold and the sliding displacement is greater than the sliding displacement threshold, obtaining a first change state of the touch area;

[0059] S24: When the humidity of the space is less than the first humidity threshold and the sliding displacement is greater than the sliding displacement threshold, obtaining a second change state of the touch area.

[0060] In this embodiment, when the touch monitoring data satisfies a preset touch displacement condition, determining that water mist exists on the mirror surface includes:

[0061] When the first change state is that the touch area increases, and the increase in the touch area is in a first preset relationship with the sliding displacement, it is determined that water droplets condensed from mist exist on the mirror surface.

[0062] In this embodiment, when the first change state is that the touch area increases, that is, it is determined that fog condensation exists under high humidity conditions. Furthermore, when the increase in the touch area is in a first preset relationship with the sliding displacement, the fog condenses into water droplets, and the water droplets slide down. At this time, it is determined that water droplets condensed from fog exist on the mirror surface.

[0063] In this embodiment, when the touch monitoring data satisfies a preset touch displacement condition, determining that water mist exists on the mirror surface includes:

[0064] When the second change state is that the touch area is reduced, and the amount of reduction in the touch area is in a second preset relationship with the sliding displacement, it is determined that there are water drops splashed from the outside on the mirror surface.

[0065] In this embodiment, when the second change state is that the touch area is reduced, that is, it is determined that there is no fog condensation under high humidity conditions. However, when the amount of reduction in the touch area and the sliding displacement are in a second preset relationship, there are water droplets, then it can be determined that there are water droplets splashed from the outside on the mirror surface.

[0066] Example 3

[0067] Based on the first embodiment above, to further improve the accuracy of touch detection data determination, this embodiment uses a preset attachment area and a preset sliding trajectory as the touch displacement conditions. Specifically, first, when a single touch area in the touch monitoring data matches the attachment area, the sliding displacement of the attachment corresponding to the single touch area is detected. Then, when the sliding displacement includes the sliding trajectory, the presence of a water droplet on the mirror surface is determined.

[0068] In this embodiment, the capacitive screen embedded in the mirror serves as the user's touchable area, and can also be the mirror area normally used by the user when the screen is off. When water droplets are attached to the area due to washing or other reasons, since the touchable area is a capacitive screen, it can detect that the capacitance characteristics of the water droplets are attached. In this embodiment, when the capacitive screen detects that the number of attachments is greater than the first preset threshold A, and based on the dual effects of gravity and mirror friction on the attachments, the capacitive screen can detect the attachments making touch tracks of water droplets sliding down. Furthermore, when the number of attachments detected is greater than the second preset threshold B, it is determined that there is a large amount of water vapor and water droplets attached to the mirror.

[0069] Figure 5 The following is a detection diagram of a mirror water mist detection method provided by an embodiment of the present invention. In this embodiment, first, after the capacitive screen detects the presence of an attachment, it detects the contact area S of the attachment; then, based on the size of the contact area S of the attachment, it roughly infers the mass A of the attachment; further, based on the contact area S and mass A, it evaluates the impact of the attachment's gravity and screen adhesion on the attachment; when the system determines that the dual effects of gravity F1 and screen adhesion F2 can cause displacement, the attachment is added to the displacement detection queue L, as shown in the following figure. Figure 5 As shown, the light gray line represents the downward sliding displacement of the water droplet under the action of gravity and friction; when the number of displacements generated in the detection queue is greater than the preset threshold, it is determined that there are a large number of water droplets attached to the mirror.
