Technical Field

[0001] This invention relates to the field of smart glasses technology, and in particular to a smart glasses control method, control device, and smart glasses. Background Technology

[0002] Currently, smart glasses such as AR glasses are gradually entering the market and being accepted by the public because they have many functions similar to mobile phones. However, as a type of eyewear product, smart glasses also have the additional need to be worn in various environments compared to mobile phones.

[0003] However, when smart glasses are moved from a cold environment to a warm environment, the lenses fog up due to the temperature change, making it difficult for users to see clearly. Users need to wipe them manually afterward, which is inconvenient for them. Summary of the Invention

[0004] The main objective of this invention is to provide a control method for smart glasses, aiming to solve the problem that smart glasses fog up when the lenses move from a cold environment to a warm environment, making them inconvenient for users.

[0005] To achieve the above objectives, the present invention proposes a smart glasses control method, comprising:

[0006] Determine if the smart glasses are in a low-temperature environment;

[0007] If the smart glasses are in a low-temperature environment, determine whether the ambient temperature of the environment where the smart glasses are located is rising too quickly.

[0008] If the ambient temperature of the environment where the smart glasses are located rises too quickly, the lenses will be heated.

[0009] Optionally, the step of determining whether the ambient temperature of the smart glasses is rising too rapidly if the smart glasses are in a low-temperature environment includes:

[0010] If the smart glasses are in a low-temperature environment, the ambient temperature will be acquired once at a preset time interval.

[0011] Based on the current first ambient temperature and the previously acquired second ambient temperature, determine whether the ambient temperature of the environment where the smart glasses are located is rising too rapidly.

[0012] Optionally, the step of determining whether the ambient temperature of the environment where the smart glasses are located has risen too rapidly based on the currently acquired first ambient temperature and the previously acquired second ambient temperature includes:

[0013] Determine whether the difference between the first ambient temperature and the previously acquired second ambient temperature is greater than a preset temperature difference.

[0014] If the difference between the first ambient temperature and the previously obtained second ambient temperature is greater than the preset temperature difference, it is determined that the temperature difference of the environment in which the smart glasses are located is too large.

[0015] If the difference between the first ambient temperature and the previously obtained second ambient temperature is not greater than the preset temperature difference, it is determined that the temperature difference in the environment where the smart glasses are located is not too large.

[0016] Optionally, the smart glasses control method further includes:

[0017] If the ambient temperature of the environment where the smart glasses are located rises too quickly, then an image of the eyes will be captured.

[0018] Based on the eye images, determine whether the user's eye state has changed from squinting to a normal state;

[0019] If the user's eye state changes from squinting to normal, the lens is confirmed to have completed defogging and the lens heating is stopped.

[0020] Optionally, after the step of heating the lenses if it is determined that the ambient temperature of the environment where the smart glasses are located is rising too quickly, the smart glasses control method further includes:

[0021] Obtain the temperature of the lens;

[0022] Determine if the lens temperature has reached the preset temperature threshold;

[0023] If the lens temperature reaches the preset temperature threshold, the lens heating will stop or the lens temperature will be reduced.

[0024] The present invention also proposes a smart glasses control device, comprising:

[0025] Memory;

[0026] Processor; and,

[0027] The smart glasses control program is stored in the memory and executed by the processor. When executed by the processor, the smart glasses control program implements the smart glasses control method as described above.

[0028] The present invention also proposes a smart glasses, comprising:

[0029] lens;

[0030] Heating assembly for heating the lens;

[0031] An ambient temperature detection module is used to detect the ambient temperature and output an ambient temperature detection signal; and,

[0032] The smart glasses control device described above is connected to the ambient temperature detection module and the heating component, respectively. The smart glasses control device is used to determine whether the smart glasses are in a low-temperature environment based on the ambient temperature detection signal output by the ambient temperature detection module; if the smart glasses are in a low-temperature environment, it determines whether the ambient temperature of the environment where the smart glasses are located is rising too fast; if the ambient temperature of the environment where the smart glasses are located is rising too fast, it controls the heating component to heat the lenses.

[0033] Optionally, the heating component is disposed in the lens, and forms a first heating region and a second heating region opposite to each other along a first preset direction, as well as a third heating region and a fourth heating region opposite to each other along a second preset direction in the lens;

[0034] The first heating area, the second heating area, the third heating area, and the fourth heating area together form a first light-transmitting part, and a second light-transmitting part is provided in the first heating area, the second heating area, the third heating area, and the fourth heating area.

[0035] Optionally, the span of the cross-sectional shape of the heating component is greater than 0 and not greater than 2 μm.

[0036] Optionally, the smart glasses further include:

[0037] A lens temperature detection module is provided on the outer periphery of the lens. The lens temperature detection module is connected to the smart glasses control device. The lens temperature detection module is used to detect the temperature of the lens and output a lens temperature detection signal to the smart glasses control device.

[0038] The smart glasses control device is also used to acquire the temperature of the lens based on the lens temperature detection signal; and to determine whether the temperature of the lens has reached a preset temperature threshold; if it is determined that the temperature of the lens has reached the preset temperature threshold, it controls the heating component to stop heating the lens.

[0039] This invention addresses the issue by determining whether the smart glasses are in a low-temperature environment. If so, it determines whether the ambient temperature is rising too rapidly. If the ambient temperature is rising too rapidly, it heats the lenses. As the lens temperature increases, the condensation on the lenses gradually disappears, allowing the smart glasses to automatically defog without manual wiping. This solves the problem of fogging when smart glasses are moved from a cold to a warm environment, making them inconvenient to use. Attached Figure Description

[0051] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0052] 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 a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0053] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0054] Currently, AR glasses and other smart glasses are gaining popularity due to their display capabilities. However, as eyewear, AR glasses, unlike smartphones, are worn and frequently switch between different temperature environments as the user moves. This invention has discovered that when a user moves from a low-temperature environment to a warmer one, the warmer air in the warmer environment condenses and fogs upon contact with the cooler lenses, resulting in fogging. A common solution is for the user to remove the glasses and wipe the fog off with a cloth, but this traditional solution is unsuitable for the future "identity" of smart glasses. Therefore, an automatic defogging solution suitable for smart glasses is urgently needed.

[0055] To address the above problems, this invention proposes a smart glasses control method, referring to... Figure 1 The control methods for smart glasses include:

[0056] Step S100: Determine whether the smart glasses are in a low-temperature environment;

[0057] The smart glasses may be equipped with an ambient temperature detection module for detecting ambient temperature and outputting an ambient temperature detection signal. The ambient temperature detection signal can be converted into a digital signal and analyzed to obtain the current ambient temperature of the smart glasses. The current ambient temperature of the smart glasses can be compared with a preset low temperature threshold of the upper limit of the low temperature ambient temperature of the dial indicator to determine whether the smart glasses are in a low temperature environment based on the comparison result.

[0058] Step S200: If the smart glasses are in a low-temperature environment, determine whether the ambient temperature of the environment where the smart glasses are located is rising too fast.

[0059] If the comparison result shows that the ambient temperature of the smart glasses is not greater than, i.e., less than or equal to, the preset low temperature threshold, then the smart glasses are in a low temperature environment; if the comparison result shows that the ambient temperature of the smart glasses is greater than the preset low temperature threshold, then the smart glasses are not in a low temperature environment.

[0060] When it is determined that the smart glasses are in a low-temperature environment, the ambient temperature change can be further determined based on the ambient temperature detection signal. Furthermore, based on the amplitude of the temperature change, it can be determined whether the ambient temperature is rising too rapidly. For example, it can first be determined whether the amplitude of the temperature change is positive or negative. If the amplitude is determined to be positive, the absolute value of the amplitude can be compared with a preset amplitude to determine whether the ambient temperature is rising too rapidly.

[0061] Step S300: If the ambient temperature of the environment where the smart glasses are located rises too quickly, the lenses are heated.

[0062] If the change in ambient temperature is positive and the absolute value of the change is not less than a preset range, then it can be determined that the ambient temperature of the environment where the smart glasses are located is rising too rapidly. Conversely, if the change in ambient temperature is negative, it indicates that the ambient temperature of the environment where the smart glasses are located is decreasing; if the change in ambient temperature is positive but not less than a preset range, it can be determined that the ambient temperature of the environment where the smart glasses are located is rising too slowly. Neither of these situations will cause fogging on the lenses; therefore, both situations can be used to determine that the ambient temperature of the environment where the smart glasses are located is not rising too rapidly.

[0063] The smart glasses may also include a heating component for heating the lenses. This component activates when the ambient temperature of the environment around the smart glasses rises too rapidly, heating the lenses to increase their temperature. This means that as the lens temperature rises, the condensation on the lenses gradually disappears, allowing the smart glasses to automatically defog without manual wiping. This solves the problem of fogging lenses when moving from a cold to a warm environment, which makes the glasses inconvenient to use.

[0064] In this embodiment, if it is determined that the smart glasses are not in a low-temperature environment, or that the ambient temperature of the environment in which the smart glasses are located has not risen too quickly, the lenses will not be heated to avoid the lens temperature rising and affecting the user's use.

[0065] Reference Figure 2 The step S200, which determines whether the ambient temperature of the smart glasses is in a low-temperature environment is rising too rapidly, includes:

[0066] Step S210: If the smart glasses are in a low-temperature environment, the ambient temperature is acquired once every preset collection time.

[0067] In this embodiment, an ambient temperature detection signal can be acquired once at a preset acquisition time interval, or the ambient temperature detection module can output an ambient temperature detection signal once at a preset acquisition time interval, and the corresponding ambient temperature can be determined based on each acquired ambient temperature detection signal, thereby realizing step S210.

[0068] The preset acquisition time can be determined through prior experiments, and the technical solution of this invention is not limited thereto. In an optional embodiment, the preset acquisition time is selected as 1 second, which can effectively avoid the lens temperature rising too quickly and affecting the lens lifespan due to excessively high ambient temperature acquisition frequency, and at the same time, it can also avoid the fogging not being eliminated in time due to excessively low acquisition frequency.

[0069] Step S220: Based on the currently acquired first ambient temperature and the previously acquired second ambient temperature, determine whether the ambient temperature of the environment where the smart glasses are located is rising too fast.

[0070] In this embodiment, the first ambient temperature is the ambient temperature determined based on the ambient temperature detection signal acquired this time, and the second ambient temperature is the ambient temperature determined based on the ambient temperature detection signal acquired in the previous acquisition. By performing corresponding calculations on the first and second ambient temperatures, the change range of the ambient temperature during the preset acquisition time can be determined, thereby determining whether the ambient temperature of the environment where the smart glasses are located has risen too rapidly based on the change range.

[0071] Optionally, step S220, which determines whether the ambient temperature of the environment where the smart glasses are located has risen too rapidly based on the currently acquired first ambient temperature and the previously acquired second ambient temperature, includes:

[0072] Step S221: Determine whether the difference between the first ambient temperature and the previously obtained second ambient temperature is greater than a preset temperature difference.

[0073] Step S222: If the difference between the first ambient temperature and the previously obtained second ambient temperature is greater than the preset temperature difference, it is determined that the temperature difference of the environment where the smart glasses are located is too large.

[0074] Step S223: If the difference between the first ambient temperature and the previously obtained second ambient temperature is not greater than the preset temperature difference, then it is determined that the temperature difference of the environment where the smart glasses are located is not too large.

[0075] In this embodiment, the magnitude of the difference between the first ambient temperature and the second ambient temperature can be determined by comparing it with a preset temperature difference. The preset temperature difference can be a positive value. Therefore, when the difference between the first ambient temperature and the second ambient temperature is greater than the preset temperature difference, it can be determined that the temperature change of the environment where the smart glasses are located is greater than the preset difference, that is, it can be determined that the temperature difference of the environment where the smart glasses are located is too large. The difference between the first ambient temperature and the previously obtained second ambient temperature not being greater than the preset temperature difference includes the following two cases: the first case is that the first ambient temperature is not greater than (less than or equal to) the second ambient temperature, in which case the difference is negative or zero; the second case is that the difference between the first ambient temperature and the second ambient temperature is less than the preset temperature difference, in which case the difference is positive. Both of these cases can determine that the temperature change of the environment where the smart glasses are located is not greater than the preset difference, that is, it can be determined that the temperature difference of the environment where the smart glasses are located is not too large.

[0076] In one optional embodiment, the preset temperature difference is set to 8°C, which can effectively prevent the preset temperature difference from being too high and failing to defog in time, and at the same time, it can also prevent the preset temperature difference from being too low and causing the lens temperature to rise too early, which is beneficial to reducing the energy consumption of smart glasses.

[0077] Reference Figure 1 The smart glasses control method further includes:

[0078] Step S400: If the ambient temperature of the environment where the smart glasses are located rises too quickly, then acquire an image of the eyes;

[0079] Step S500: Based on the eye image, determine whether the user's eye state has changed from squinting to a normal state;

[0080] Step S600: If the user's eye state changes from squinting to normal, then the lens is confirmed to have completed defogging and the lens heating is stopped.

[0081] In this embodiment, the smart glasses may also be equipped with an ET (eye tracking) camera module for detecting eye movements. Therefore, step S400 can be achieved by acquiring the eye image output by the ET camera module after detecting eye movements.

[0082] Understandably, when the lens fogs up, the user's eyes squint, and when the lens defogs, the user's eyes return to a normal state. Therefore, by judging whether the user's eyes have changed from a squinting state to a normal state based on the eye image, it can be determined whether the lens defogging is complete. Step S500 can first obtain the user's current eye information based on the eye image, and then match the current eye information with preset abnormal eye information to determine whether the user's eye state has entered a squinting state. If the current eye information matches the preset abnormal eye information, it can be determined that the user's eye state has entered a squinting state; if the current eye information does not match the preset abnormal eye information, it can be determined that the user's eye state has not entered a squinting state.

[0083] The current eye information can include at least one of the current eye height and current eye width. Similarly, the preset abnormal eye information also includes at least one of the preset abnormal eye height and preset abnormal eye width. The preset abnormal eye height can be the eye height when the user's eyes are squinting, and the preset abnormal eye width can be the eye width when the user's eyes are squinting. It should be noted that since the eye height and width when the user's eyes are squinting are both smaller than the height and width when the eyes are in a normal state, it is possible to determine whether the user's eye state is squinting by judging whether the current eye information matches the preset abnormal eye width information.

[0084] If it's determined that the user's eyes are squinting, a new eye image can be acquired. This new image is then used to update the user's current eye information. The updated eye information can be matched with preset normal eye information to determine if the user's eye state has returned to normal. If the current eye information matches the preset normal eye information, the user's eye state is considered normal, defogging of the lens is complete, and lens heating can be stopped. If the current eye information does not match the preset normal eye information, the user's eye state is not normal and they are still squinting. In this case, defogging of the lens is incomplete, and lens heating should continue.

[0085] Correspondingly, the preset normal eye information also includes at least one of the preset normal eye height information and the preset normal eye width information. The preset normal eye height information can be the eye height of the user's eyes in a normal state, and the preset normal eye width information can be the eye width of the user's eyes in a normal state.

[0086] In this way, heating can be automatically stopped after the lens defogging is completed, which further improves the user's convenience.

[0087] Reference Figure 3If it is determined whether the ambient temperature of the environment where the smart glasses are located rises too quickly, then after step S300 of heating the lenses, the smart glasses control method further includes:

[0088] Step S700: Obtain the temperature of the lens;

[0089] Step S800: Determine whether the temperature of the lens has reached the preset temperature threshold;

[0090] Step S900: If the temperature of the lens reaches the preset temperature threshold, stop heating the lens or lower the temperature of the lens.

[0091] In this embodiment, the smart glasses may also include a lens temperature detection module for detecting lens temperature. This module can detect the lens temperature in real time after heating and output a lens temperature detection signal. The lens temperature detection signal can be converted into a digital signal and analyzed to obtain the lens temperature. The lens temperature can be compared with a preset temperature threshold to determine if the lens temperature has reached the preset threshold. Specifically: if the comparison result shows that the lens temperature is greater than or equal to the preset temperature threshold, it can be determined that the lens temperature has reached the preset temperature threshold. At this point, heating the lens can be stopped or the lens temperature can be reduced to avoid burning the skin around the user's eyes due to excessive lens temperature. If the comparison result shows that the lens temperature is less than the preset temperature threshold, it can be determined that the lens temperature has not reached the preset temperature threshold. At this point, the lens heating temperature can be increased or maintained unchanged to eliminate fogging on the lens.

[0092] In this way, while automatically removing fog from the lenses, the temperature of the lenses can be too high and burn the skin near the user's glasses, which helps to improve the safety of the technical solution of this invention.

[0093] The present invention also proposes a smart glasses control device.

[0094] Reference Figure 4 The smart glasses control device includes:

[0095] Memory 11; and,

[0096] The processor 12 stores a smart glasses control program on the memory 11 and executes it. When the smart glasses control program is executed by the processor 12, it implements the smart glasses control method as described above.

[0097] The specific steps of the smart glasses control method are as described in the above embodiments. Since this control device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The memory 11 can be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk storage device. The memory 11 can also be a storage device independent of the aforementioned control device. The processor 12 can be a CPU. The memory 11 and the processor 12 are connected by a communication bus 13, which can be a UART bus or an I2C bus.

[0098] This invention also proposes a smart glasses, with reference to Figures 5 to 7 The smart glasses include a lens 21, a heating component 22, an ambient temperature detection module 23, and a smart glasses control device 24. The specific structure of the smart glasses control device 24 is as described in the above embodiments. Since the smart glasses adopt all the technical solutions of all the above embodiments, they have at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0099] The heating component 22 is used to heat the lens 21; the ambient temperature detection module 23 is used to detect the ambient temperature and output an ambient temperature detection signal; the smart glasses control device 24 is connected to the ambient temperature detection module 23 and the heating component 22 respectively, and the smart glasses control device 24 is used to determine whether the smart glasses are in a low temperature environment according to the ambient temperature detection signal output by the ambient temperature detection module 23; if the smart glasses are in a low temperature environment, it determines whether the ambient temperature of the environment where the smart glasses are located is rising too fast; if the ambient temperature of the environment where the smart glasses are located is rising too fast, it controls the heating component 22 to heat the lens 21.

[0100] In an optional embodiment, the smart glasses may also include a driving component 33, which may be connected to the smart glasses control device 24 and the heating component 22 respectively. The smart glasses control device 24 may control the driving component 33 to drive the heating component 22 to heat the lens 21.

[0101] Optionally, the heating component 22 is disposed in the lens 21, and forms a first heating region A1 and a second heating region A2 opposite to each other along a first preset direction, as well as a third heating region and a fourth heating region A4 opposite to each other along a second preset direction in the lens 21;

[0102] The first heating area A1, the second heating area A2, the third heating area A3, and the fourth heating area A4 together form a first light-transmitting part B1, and a second light-transmitting part B2 is provided in the first heating area A1, the second heating area A2, the third heating area A3, and the fourth heating area A4.

[0103] In this embodiment, the heating component 22 can be a copper wire. One of the first preset direction and the second preset direction can be the length direction of the lens 21, and the other can be the width direction of the lens 21. The first heating region A1, the second heating region A2, the third heating region A3, and the fourth heating region A4 can be in a near-trapezoidal shape. The lower bases of the four heating regions (A1-A4) can be sequentially connected to form a first light-transmitting portion B1 enclosed at the center of the lens 21, and each of the four heating regions (A1-A4) can have a second light-transmitting portion B2 enclosed by the heating component 22. The upper bases and two waists of the four heating regions (A1-A4) can also be sequentially connected to form a third light-transmitting portion B3 between the four heating regions and the edge of the lens 21. In this embodiment, the shapes of the first light-transmitting portion B1, the second light-transmitting portion B2, and the third light-transmitting portion B3 are not limited. Figures 5 to 6 An example of the shape presented by the first light-transmitting part B1, the second light-transmitting part B2, and the third light-transmitting part B3 is shown. Figures 5 to 6 In the embodiment shown, the first light-transmitting part B1 is nearly rectangular in shape, the second light-transmitting part B2 is nearly rectangular, nearly trapezoidal, and nearly triangular in shape, and the third light-transmitting part B3 is nearly triangular in shape.

[0104] With this configuration, the heating efficiency of the lens 21 can be effectively improved by placing the heating component 22 in the lens 21. Furthermore, by setting the first light-transmitting part and the second light-transmitting part, the user's field of vision can be minimized while adding the heating component 22 to the lens 21.

[0105] Optionally, refer to Figures 5 to 8 The span of the cross-sectional shape of the heating component 22 is greater than 0 and not greater than 2 μm.

[0106] In this embodiment, the span of the cross-sectional shape of the heating component 22 can be the linewidth projected onto the plane where the lens 21 is located; if the cross-sectional shape of the heating component 22 is circular, then its span is the diameter of the circle. The copper lines of the heating component 22 can be etched to a non-visible state of 2µm or less using photolithography, thereby allowing the lens 21 with the heating component 22 to have a light transmittance of over 95%, exceeding the resolution of the human eye, and further avoiding affecting the user's field of vision.

[0107] Optionally, the smart glasses further include:

[0108] Lens temperature detection module 25 is located on the outer periphery of the lens 21. The lens temperature detection module 25 is connected to the smart glasses control device 24. The lens temperature detection module 25 is used to detect the temperature of the lens 21 and output the lens 21 temperature detection signal to the smart glasses control device 24.

[0109] The smart glasses control device 24 is also used to obtain the temperature of the lens 21 based on the temperature detection signal of the lens 21; and to determine whether the temperature of the lens 21 has reached a preset temperature threshold; if the temperature of the lens 21 reaches the preset temperature threshold, the heating component 22 is controlled to stop heating the lens 21.

[0110] In this embodiment, the lens temperature detection module 25 can be implemented using a metal coil. The size and shape of the metal coil can be determined according to different lenses 21, and this embodiment does not limit this. The smart glasses control device 24 can convert the lens 21 temperature detection signal into a digital signal, analyze it to obtain the lens 21 temperature, and compare the lens 21 temperature with a preset temperature threshold to determine whether the lens 21 temperature has reached the preset temperature threshold. Specifically: if the comparison result is that the lens 21 temperature is greater than or equal to the preset temperature threshold, it can be determined that the lens 21 temperature has reached the preset temperature threshold. At this time, the heating of the lens 21 can be stopped or the lens 21 temperature can be reduced to avoid the lens 21 temperature being too high and burning the skin around the user's eyes; if the comparison result is that the lens 21 temperature is less than the preset temperature threshold, it can be determined that the lens 21 temperature has not reached the preset temperature threshold. At this time, the heating temperature of the lens 21 can be increased or the heating temperature of the lens 21 can be kept unchanged to eliminate the fog on the lens 21.

[0111] In this way, while automatically removing fog from the lens 21, the temperature of the lens 21 can be prevented from becoming too high and burning the skin near the user's eyes, thus improving the safety of the technical solution of the present invention. In addition, by placing the lens temperature detection module 25 on the outer periphery of the lens 21, the lens temperature detection module 25 can be implemented while preventing it from affecting the user's field of vision.

[0112] In an optional embodiment, the smart glasses may further include a front frame 26, a left temple 27, and a right temple 28. The smart glasses control device may be located in either the left temple 27 or the right temple 28. A left frame 29 and a right frame 30 are formed in the front frame 26. A lens 21 may be correspondingly mounted on each of the left and right frames 29 and 30. An ET camera module 31 may be provided on the sidewalls of the left and right frames 29 and 30 for contacting the lens 21, and an IR-LED 32 may also be provided on these sidewalls to assist the ET camera module 31 in capturing images. A nose pad may also be provided on the front frame 26, and an ambient temperature detection module 23 may be located above the nose pad. The ambient temperature detection module 23 may be located on the central axis of the smart glasses to ensure the accuracy of ambient temperature detection.
