[0056] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0057] The terms "including" and "having" in the specification and claims of this application and the above drawings, as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may include steps or units that are not listed.

[0058] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0059] Next, a method for adjusting the display brightness of smart glasses provided in an embodiment of the present application is described in detail. Figure 1 A flowchart of a method for adjusting display brightness of smart glasses provided in an embodiment of the present application, the method comprising:

[0060] S101: Acquire the ambient light brightness.

[0061] In an embodiment of the present application, an ambient light sensor may be provided on the smart glasses to collect the ambient light brightness.

[0062] Smart glasses can be smart products such as Bluetooth audio glasses, AR (Augmented Reality) glasses, VR (Virtual Reality) glasses, etc. In the embodiments of the present application, there is no limitation on the type of smart glasses.

[0063] S102: Receive the lens magnetic field strength fed back by the magnetic sensor.

[0064] In practical applications, multiple lenses with different transmittances can be prepared in advance for users to choose from. When the brightness of the user's environment changes or the user's needs change, the lenses can be replaced in order to provide the user with a better visual experience. Lenses with different transmittances can achieve different ambient light brightness. In the embodiment of the present application, the lenses can be electrochromic shading lenses.

[0065] For example, when the user needs a higher degree of perspective, the lens with high transmittance can be replaced. When the brightness of the environment in which the user is located becomes brighter, in order to reduce the stimulation of strong light to the user's eyes, the lens with low transmittance can be replaced, thereby reducing the brightness of the ambient light entering the eye.

[0066] In the embodiment of the present application, in order to realize the convenient replacement of the lens, the lens and the smart glasses can be detachable by magnetic attraction. A magnetic magnet is set on the lens, and a magnetic magnet is set at the corresponding position of the front frame of the smart glasses. The magnetic magnet of the lens and the magnetic magnet of the front frame of the smart glasses can fit tightly, so that the lens is fixed on the front frame of the smart glasses. The magnetic magnet can be a hard magnet or a soft magnet.

[0067] In practical applications, a magnetic sensor can be set on the smart glasses to detect the magnetic field strength of the lens.

[0068] S103: Based on the corresponding relationship between the magnetic field strength and the transmittance, determine the transmittance of the lens that matches the magnetic field strength of the lens.

[0069] In a specific implementation, the corresponding relationship between different magnetic field intensities and transmittances may be established in advance, and the corresponding relationship may be recorded in the form of a list.

[0070] Taking into account the influence of various factors, even for the same lens, there will be slight differences in the magnetic field strength of the lens detected by the magnetic sensor multiple times. Therefore, the magnetic field strength range corresponding to each transmittance can be recorded in the corresponding relationship list.

[0071] After obtaining the lens magnetic field strength fed back by the magnetic sensor, the magnetic field strength range to which the lens magnetic field strength belongs can be obtained by querying the corresponding relationship list. The transmittance corresponding to the magnetic field strength range is the lens transmittance matched by the lens magnetic field strength.

[0072] S104: Determine the display brightness according to the lens transmittance and the ambient light brightness, and adjust the brightness of the display component to the display brightness.

[0073] The lens transmittance and the ambient light brightness determine the brightness of the ambient light entering the eye, that is, the brightness of the ambient light entering the human eye.

[0074] When the user wears smart glasses, in order to give the user a better visual experience, in addition to considering the brightness of the ambient light entering the eye, the display brightness of the virtual image display is also considered. In the embodiment of the present application, in order to achieve automatic adjustment of the display brightness, a corresponding relationship list of the transmittance, the ambient light brightness range and the display brightness can be established.

[0075] By querying the correspondence list of transmittance, ambient light brightness range and display brightness, the display brightness matching the lens transmittance and ambient light brightness can be obtained. After determining the display brightness, the application processor of the smart glasses can adjust the brightness of the display component to the display brightness.

[0076] It can be seen from the above technical solution that the application processor of the smart glasses obtains the ambient light brightness. The front frame of the smart glasses can be provided with a magnet, and the lens can be magnetically attracted to the smart glasses by providing a magnet, so that the lenses with different transmittances can be conveniently replaced. The application processor receives the lens magnetic field strength fed back by the magnetic sensor; based on the corresponding relationship between the magnetic field strength and the transmittance, the lens transmittance that matches the lens magnetic field strength is determined. According to the lens transmittance and the ambient light brightness, the display brightness is determined, and the brightness of the display component is adjusted to the display brightness. In this technical solution, the convenient replacement of lenses with different transmittances can be achieved by magnetic attraction, so as to better adapt to the change of ambient brightness, realize the adjustment of the intensity of the external ambient light entering the eye and the effect of different degrees of perspective of the outside world. Magnets with different magnetic field strengths are set on lenses with different transmittances. By obtaining the magnetic field strength of the lens, the actual transmittance of the lens currently magnetically attracted to the smart glasses can be identified. The display brightness is determined based on the actual transmittance and the ambient light brightness, and the display brightness of the display component is intelligently adjusted, so that users can get a better visual experience.

[0077] The lens includes a left lens and a right lens. In practical applications, the lens may be a left lens and a right lens that are independent of each other, or may be an integrated lens that includes both the left lens and the right lens.

[0078] In the case where the lenses are independent left and right lenses, a left magnetic sensor and a right magnetic sensor can be respectively provided on the smart glasses. The left magnetic sensor corresponds to the left lens, and the right magnetic sensor corresponds to the right lens.

[0079] Considering that in actual applications, when the user replaces the left lens and the right lens, the transmittance of the replaced left lens and the right lens may be inconsistent, which will affect the user's visual experience. Therefore, after the user replaces the left lens and the right lens, it is possible to further determine whether the transmittance of the left lens and the right lens is consistent. In the embodiment of the present application, different magnetic field strengths are used to characterize different transmittances. Therefore, it is possible to identify whether the transmittance of the left lens and the right lens is consistent based on the deviation between the magnetic field strength detected by the left magnetic sensor and the magnetic field strength detected by the right magnetic sensor.

[0080] In a specific implementation, when the lenses are not installed, the application processor of the smart glasses can receive the left initial magnetic field strength fed back by the left magnetic sensor, and receive the right initial magnetic field strength fed back by the right magnetic sensor; when the lenses are installed, it receives the left magnetic field strength fed back by the left magnetic sensor, and receives the right magnetic field strength fed back by the right magnetic sensor.

[0081] Based on the left magnetic field strength and the left initial magnetic field strength, the left magnetic field strength change can be determined; based on the right magnetic field strength and the right initial magnetic field strength, the right magnetic field strength change can be determined.

[0082] In a specific implementation, the absolute value of the difference between the left magnetic field strength and the left initial magnetic field strength can be used as the left magnetic field strength change; the absolute value of the difference between the right magnetic field strength and the right initial magnetic field strength can be used as the right magnetic field strength change.

[0083] It is determined whether the change in the left magnetic field strength and the change in the right magnetic field strength are greater than a set threshold. The value of the set threshold can be set based on the magnetic field strength deviation allowed under the same transmittance.

[0084] When the change in the magnetic field strength on the left and the change in the magnetic field strength on the right are greater than the set threshold, it means that the transmittance of the left lens and the right lens are inconsistent. At this time, a prompt message of inconsistent lens transmittance can be displayed to facilitate users to replace the lenses in time.

[0085] Considering that both the lenses and the front frames of the smart glasses are equipped with magnetic magnets, the magnetic sensor installed on the smart glasses will be affected by the magnetic magnets on the front frame of the smart glasses when detecting the magnetic field strength of the lenses. Therefore, the magnetic field strength of the lenses can be determined by calculating the difference between the magnetic field strength when the lenses are not installed and the magnetic field strength after the lenses are installed.

[0086] When the change in the left magnetic field strength and the change in the right magnetic field strength are less than or equal to the set threshold, it means that the transmittance of the left lens and the right lens are consistent. At this time, based on the correspondence between the magnetic field strength and the transmittance, the steps of determining the lens transmittance that matches the lens magnetic field strength can be determined; wherein the lens magnetic field strength can be the change in the left magnetic field strength or the change in the right magnetic field strength.

[0087] When the lens is an integrated lens including a left lens and a right lens, the lens magnetic field strength received by the application processor of the smart glasses may be the change in magnetic field strength generated when the lens is not installed and when the lens is installed, as fed back by the magnetic sensor.

[0088] In the embodiment of the present application, the actual magnetic field strength of the lens is determined based on the magnetic field strength before and after the lens is installed, which can effectively reduce the influence of the magnetic attraction magnet set on the front frame of the smart glasses on the magnetic sensor, and improve the accuracy of determining the magnetic field strength of the lens, so that the transmittance of the lens can be accurately identified based on the magnetic field strength of the lens.

[0099] The display unit is used to display a prompt message that the lens transmittance is inconsistent when the change in the left magnetic field strength and the change in the right magnetic field strength are greater than a set threshold.

[0100] Optionally, the transmittance determination unit is used to determine the lens transmittance that matches the magnetic field strength of the lens based on the correspondence between magnetic field strength and transmittance when the change in the left magnetic field strength and the change in the right magnetic field strength are less than or equal to a set threshold; wherein the lens magnetic field strength is the change in the left magnetic field strength or the change in the right magnetic field strength.

[0101] Optionally, when the lens is an integrated lens including a left lens and a right lens, the receiving unit is used to receive the change in magnetic field intensity generated when the lens is not installed and when the lens is installed, which is fed back by the magnetic sensor.

[0103] Figure 2 The description of the features in the corresponding embodiments can be found in Figure 1 The relevant descriptions of the corresponding embodiments will not be repeated here one by one.

[0104] It can be seen from the above technical solution that the application processor of the smart glasses obtains the ambient light brightness. The front frame of the smart glasses can be provided with a magnet, and the lens can be magnetically attracted to the smart glasses by providing a magnet, so that the lenses with different transmittances can be conveniently replaced. The application processor receives the lens magnetic field strength fed back by the magnetic sensor; based on the corresponding relationship between the magnetic field strength and the transmittance, the lens transmittance that matches the lens magnetic field strength is determined. According to the lens transmittance and the ambient light brightness, the display brightness is determined, and the brightness of the display component is adjusted to the display brightness. In this technical solution, the convenient replacement of lenses with different transmittances can be achieved by magnetic attraction, so as to better adapt to the change of ambient brightness, realize the adjustment of the intensity of the external ambient light entering the eye and the effect of different degrees of perspective of the outside world. Magnets with different magnetic field strengths are set on lenses with different transmittances. By obtaining the magnetic field strength of the lens, the actual transmittance of the lens currently magnetically attracted to the smart glasses can be identified. The display brightness is determined based on the actual transmittance and the ambient light brightness, and the display brightness of the display component is intelligently adjusted, so that users can get a better visual experience.

[0105] Figure 3A schematic diagram of the structure of a smart glasses provided in an embodiment of the present application, comprising an application processor 31, an ambient light sensor 32, a magnetic sensor 33, a display component 34, and a magnetic magnet 35 disposed at the front frame of the smart glasses; wherein the magnetic magnet 35 is used to closely fit with the magnetic magnet 35 on the lens by magnetic attraction;

[0106] The ambient light sensor 32 is connected to the application processor 31 and is used to obtain the ambient light brightness and transmit the ambient light brightness to the application processor 31;

[0107] The application processor 31 is connected to the magnetic sensor 33 and the display component 34 respectively, and is used for receiving the lens magnetic field strength fed back by the magnetic sensor 33; determining the lens transmittance matching the lens magnetic field strength based on the corresponding relationship between the magnetic field strength and the transmittance; determining the display brightness according to the lens transmittance and the ambient light brightness transmitted by the light sensor; and adjusting the display component 34 to the display brightness.

[0108] The magnetic sensor 33 is used to detect the magnetic field strength of the lens. In the embodiment of the present application, the setting position of the magnetic sensor 33 can be determined according to the setting position of the magnet on the lens.

[0109] The magnetic sensor 33 can sense the magnetic field of the magnetic magnet 35, so Figure 3 The dotted line in the figure indicates that the magnetic sensor 33 is used to sense the magnetic field of the magnetic attraction magnet 35.

[0110] A feasible implementation method is to set the magnetic sensor 33 at a position directly opposite to the magnetic magnet 35 on the front frame of the smart glasses, so as to detect the magnetic field strength when the magnetic magnet 35 on the front frame of the smart glasses is tightly fitted with the magnetic magnet 35 on the lens through magnetic attraction.

In order to clearly show the corresponding positions of the magnetic magnet 35 on the lens and the magnetic magnet on the front frame of the smart glasses, Figure 4 A gap is set between the lens and the front frame of the smart glasses. In actual application, when the lens is installed on the smart glasses, the lens and the front frame of the smart glasses will fit tightly together, and there will be almost no gap. Figure 4 The long strip on the left side of the middle represents the lens, on which a magnetic magnet 35 is arranged, and the position of the magnetic magnet 35 corresponds to the magnetic magnet 35 on the front frame of the smart glasses, so that the magnetic magnet 35 can be closely fitted with the magnetic magnet 35 on the front frame of the smart glasses. The magnetic sensor 33 can be arranged directly behind the magnetic magnet 35 on the front frame of the smart glasses, and can detect the magnetic field strength before the lens is installed, and the magnetic field strength after the lens is installed, and the difference between the two magnetic field strengths is the magnetic field strength of the lens.

[0112] In addition to setting the magnetic magnet 35 on the lens, the detection magnet 36 can also be set on the lens. Therefore, another feasible implementation method is to set the magnetic sensor 33 on the smart glasses at a position directly opposite to the detection magnet 36 when the lens is installed on the smart glasses. When the magnetic magnet 35 at the front frame of the smart glasses is closely attached to the magnetic magnet 35 on the lens by magnetic attraction, the magnetic sensor 33 is in a directly opposite position to the detection magnet 36 on the lens, so as to obtain the magnetic field strength generated by the detection magnet 36.

In order to clearly show the corresponding positions of the detection magnet 36 on the lens and the magnetic sensor 33 on the front frame of the smart glasses, Figure 5 A gap is set between the lens and the front frame of the smart glasses. In actual application, when the lens is installed on the smart glasses, the lens and the front frame of the smart glasses will fit tightly together, and there will be almost no gap. Figure 5 The long strip on the left side of the middle represents the lens, on which a magnetic magnet 35 and a detection magnet 36 are arranged. The magnetic magnet 35 corresponds to the position of the magnetic magnet 35 on the front frame of the smart glasses, and can be closely fitted with the magnetic magnet 35 on the front frame of the smart glasses. The magnetic sensor 33 can be arranged at a position directly opposite to the detection magnet 36, and can detect the magnetic field strength of the detection magnet 36 after the lens is installed, and the magnetic field strength is the magnetic field strength of the lens.

[0114] In the embodiment of the present application, the lens can be an integrated lens including a left lens and a right lens. For this type of lens, in order to install the lens on the smart glasses, at least one magnetic magnet 35 is provided on the lens, and correspondingly, at least one magnetic magnet 35 is also provided on the front frame of the smart glasses.

[0115] The number of the magnetic magnets 35 arranged on the lens is the same as the number of the magnetic magnets 35 arranged on the front frame of the smart glasses, and the positions correspond one to one.

[0116] In practical applications, in order to increase the firmness of the lens when it is installed on the smart glasses, two or more magnetic magnets 35 can be set on the lens, and correspondingly, a corresponding number of magnetic magnets 35 are set at corresponding positions on the front frame of the smart glasses.

[0117] In the embodiment of the present application, the lenses may also be independent left lenses and right lenses. For this type of lenses, it is necessary to set at least one magnetic magnet 35 for each lens on the front frame of the smart glasses, which are the first magnetic magnet 35 corresponding to the position of the magnetic magnet on the left lens and the second magnetic magnet 35 corresponding to the position of the magnetic magnet on the right lens.

[0118] The number of magnetic magnets 35 provided on the left lens and the right lens is the same. In practical applications, in order to increase the firmness of the lens when it is installed on the smart glasses, two or more magnetic magnets 35 can be provided on each lens, and correspondingly, a corresponding number of magnetic magnets 35 are provided at corresponding positions of the front frame of the smart glasses.

[0119] Figure 6 A schematic diagram of deploying magnetic magnets on smart glasses provided in an embodiment of the present application, Figure 6 Taking the example of a left lens and a right lens that are independent of each other on the front frame of smart glasses, two magnetic magnets 35 can be set for each lens, and magnetic magnets 35 are also set at the corresponding positions of the front frame of the smart glasses, so that the lenses can be fixed on the front frame of the smart glasses. The magnetic magnets 35 on the lenses will fit tightly with the magnetic magnets 35 on the front frame of the smart glasses, so Figure 6 Only the magnetic attraction magnets on the lens are shown.

[0120] It should be noted that when the left lens and the right lens are two independent lenses, a corresponding magnetic sensor 33 needs to be set for each lens on the smart glasses, that is, the magnetic sensor 33 may include a left magnetic sensor 33 and a right magnetic sensor 33;

[0121] The application processor 31 is connected to the left magnetic sensor 33 and the right magnetic sensor 33 respectively, and is used to receive the left initial magnetic field strength fed back by the left magnetic sensor 33 and the right initial magnetic field strength fed back by the right magnetic sensor 33 when the lens is not installed; and to receive the left magnetic field strength fed back by the left magnetic sensor 33 and the right magnetic field strength fed back by the right magnetic sensor 33 when the lens is installed. Based on the left magnetic field strength and the left initial magnetic field strength, the left magnetic field strength change is determined; based on the right magnetic field strength and the right initial magnetic field strength, the right magnetic field strength change is determined.

[0122] When the change in the magnetic field strength on the left and the change in the magnetic field strength on the right are greater than the set threshold, a prompt message indicating that the lens transmittance is inconsistent is displayed.

[0123] When the change in the left magnetic field strength and the change in the right magnetic field strength are less than or equal to the set threshold, a step is performed to determine the lens transmittance that matches the lens magnetic field strength based on the correspondence between the magnetic field strength and the transmittance; wherein the lens magnetic field strength is the change in the left magnetic field strength or the change in the right magnetic field strength.

[0125] It can be seen from the above technical scheme that the smart glasses include an application processor, an ambient light sensor, a magnetic sensor, a display component and a magnetic magnet arranged at the front frame of the smart glasses. Among them, the magnetic magnet is used to fit tightly with the magnetic magnet on the lens by magnetic attraction. The lens is magnetically attracted to the smart glasses by setting a magnet, so that lenses with different transmittances can be easily replaced. The ambient light sensor is connected to the application processor and can transmit the acquired ambient light brightness to the application processor. The application processor is connected to the magnetic sensor and the display component respectively, and is used to receive the lens magnetic field strength fed back by the magnetic sensor; based on the corresponding relationship between the magnetic field strength and the transmittance, the lens transmittance matched with the lens magnetic field strength is determined; according to the lens transmittance and the ambient light brightness transmitted by the light sensor, the display brightness is determined; and the display component is adjusted to the display brightness. In this technical scheme, lenses with different transmittances can be easily replaced by magnetic attraction, so as to better adapt to the change of ambient brightness, realize the adjustment of the intensity of the external ambient light entering the eye and the effect of different degrees of perspective of the outside world. Magnets with different magnetic field strengths are set on lenses with different transmittances. The application processor can identify the actual transmittance of the lens currently magnetically attracted to the smart glasses by obtaining the magnetic field strength of the lens. The display brightness is determined based on the actual transmittance and the ambient light brightness, thereby realizing intelligent adjustment of the display brightness of the display component, so that users can have a better visual experience.
