[0029] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0030] See also Figure 1 , Figure 2 and Figure 3 , the embodiment of the present application provides a control method. The control method is used for the wearable device 100. The control method includes:

[0031] Step S11: determining a relative distance according to data output by the trigger device 1001 of the wearable device 100, where the relative distance is the distance between the trigger device 1001 and the target object;

[0032] Step S12: when determining, based on the relative distance, that the wearable device 100 is approaching the target object, controlling the display 40 of the wearable device 100 to display at a first brightness;

[0033] Step S13: When the relative distance decreases to be less than a preset first distance threshold, the display 40 is controlled to display at a second brightness, which is greater than the first brightness.

[0034] See also Figure 4, the embodiment of the present application provides a wearable device 100. The wearable device 100 includes a processor 101 and a trigger device 1001, the processor 101 is connected to the trigger device 1001, the processor 101 is used to determine the relative distance according to the data output by the trigger device 1001 of the wearable device 100, the relative distance is the distance between the wearable device 100 and the target object; and is used to control the display 40 of the wearable device 100 to display at a first brightness when the wearable device 100 is approaching the target object according to the relative distance; and is used to control the display 40 to display at a second brightness when the relative distance is reduced to less than a preset first distance threshold, and the second brightness is greater than the first brightness.

[0035] In the control method and wearable device 100 of the implementation mode of the present application, when the user puts on the wearable device 100, the display 40 first displays at a lower first brightness, and then displays at a higher second brightness after the user puts on the wearable device 100. This can save power to extend battery life, and can also transition through the first brightness before the display 40 displays at the second brightness to improve visual experience, which is conducive to improving user experience.

[0036] In order to save energy, related technologies usually turn off the display by setting a button on the wearable device body or handle, or set an automatic shutdown time to control the working state of the display, such as starting the automatic shutdown timer when no operation is detected. However, the operation of the button is cumbersome, resulting in a poor user experience. The waiting time for automatic shutdown is not flexible and is prone to waste power.

[0037] Specifically, in one example, because the key operation is cumbersome, the user forgets to press the button after using the wearable device, causing the display to continue to light up for a period of time, or even until the battery is completely exhausted, and then the display is turned off.

[0038] In another example, a user takes off the wearable device for a period of time while using it. Since the user wants to continue using it later, he does not press the button to turn it off. Therefore, the display is still in working state during the period of time, wasting power.

[0039] In another example, the set auto-off time is too short, and the display is automatically turned off in the gap between user operations, affecting the user experience.

[0040] In another example, the automatic shutdown time is set too long. After the user takes off the wearable device, the display continues to work normally for a long time, resulting in a waste of power.

[0041] The control method of the embodiment of the present application does not require the user to perform other triggering actions other than wearing the device, nor does it require setting the automatic shutdown time. It is simple, convenient, flexible, and can improve the user experience and save power to extend the battery life. Moreover, when the user wears the wearable device 100, the distance between the trigger device 1001 and the target object gradually decreases, and the display 40 is first controlled to display at the first brightness. When the distance between the trigger device 1001 and the target object decreases to less than the preset first distance threshold, the display is controlled to display at the second brightness, thereby forming a brightness transition, making the user's visual experience smoother, which is conducive to improving the user experience.

[0042] In addition, controlling the display 40 to display at the first brightness can also save power while prompting the user. It can be understood that when the user wears the wearable device 100, controlling the display 40 to display at the first brightness can prompt the user that the wearable device 100 has sensed the user's action, and continuing to wear the display 40 will display at the second brightness. In this way, the user can understand the current state of the wearable device 100 during the wearing process without having to wait until it is fully worn, so that corresponding measures can be taken in time when the wearable device 100 is damaged or not powered on.

[0043] Specifically, the wearable device 100 is, for example, a head mounted display device (HMD). The head mounted display device can send optical signals to the user's eyes after the user wears the head mounted display device through the cooperation of the computing system and the optical system, thereby achieving different effects such as virtual reality (VR), augmented reality (AR) and mixed reality (MR). The wearable device 100 can also be a hand-worn device such as a smart watch or a smart bracelet. The specific form of the wearable device 100 is not limited here.

[0044] For ease of understanding, the wearable device 100 of the embodiment of the present application is described in detail by taking a head-mounted display device as an example. The wearable device 100 can be an integrated head-mounted display device or a split head-mounted display device.

[0045] See also Figure 3 and Figure 5 The electronic device 100 according to the embodiment of the present application includes a housing 20 , a supporting component 30 , a display 40 , a light guiding component 70 , and a light quantity adjusting component 80 .

[0046] The housing 20 is an external component of the wearable device 100, and plays a role in protecting and fixing the internal components of the wearable device 100. The housing 20 can surround the internal components, and can prevent direct damage to these internal components caused by external factors.

[0047] Specifically, in this embodiment, the housing 20 can be used to fix at least one of the display 40, the light guide component 70 and the trigger device 1001. Figure 2 In the example of FIG. 1 , the housing 20 is formed with a housing chamber 22 , and the display 40 , the light guide member 70 , and the light quantity adjustment member 80 are housed in the housing chamber 22 .

[0048] The housing 20 further includes a housing top wall 24, a housing bottom wall 26, and a housing side wall 28. A notch 262 is formed in the middle of the housing bottom wall 26 toward the housing top wall 24. In other words, the housing 20 is roughly in a "B" shape. When the user wears the wearable device 100, the wearable device 100 can be placed on the bridge of the user's nose through the notch 262, which can ensure both the stability of the wearable device 100 and the comfort of the user.

[0049] The wearable device 100 may further include a nose bridge 264 disposed in the notch 262, and the nose bridge 264 is detachably connected to the bottom wall 26 of the housing. In this way, the user can wear the device more comfortably and improve the user experience. In addition, the nose bridge 264 can adapt to different nose bridge heights through an adjustment device, thereby improving the adaptability of the wearable device 100. The nose bridge 264 may also include different models, and the user can select different models of nose bridges 264 to be assembled to the wearable device 100 according to their own needs.

[0050] In addition, the housing 20 can be formed by processing aluminum alloy using a computerized numerical control (CNC) machine tool, or can be formed by injection molding of polycarbonate (PC) or PC and acrylonitrile butadiene styrene plastic (ABS). The specific manufacturing method and specific material of the housing 20 are not limited here.

[0051] The support component 30 is used to support the wearable device 100. When the user wears the wearable device 100, the wearable device 100 can be fixed on the user's head through the support component 30. Figure 2 In the example shown in FIG. 4 , the supporting member 30 includes a first bracket 32 ​​, a second bracket 34 and an elastic band 36 .

[0052] The first bracket 32 ​​and the second bracket 34 are symmetrically arranged about the notch 262. Specifically, the first bracket 32 ​​and the second bracket 34 are rotatably arranged at the edge of the housing 20. When the user does not need to use the wearable device 100, the first bracket 32 ​​and the second bracket 34 can be stacked close to the housing 20 for easy storage. When the user needs to use the wearable device 100, the first bracket 32 ​​and the second bracket 34 can be unfolded to realize the supporting function of the first bracket 32 ​​and the second bracket 34.

[0053] A first bending portion 322 is formed at one end of the first bracket 32 ​​away from the housing 20, and the first bending portion 322 is bent toward the housing bottom wall 26. In this way, when the user wears the wearable device 100, the first bending portion 322 can be placed on the user's ear, so that the wearable device 100 is not easy to slip off.

[0054] Similarly, a second bending portion 342 is formed at one end of the second bracket 34 away from the housing 20. The explanation and description of the second bending portion 342 can refer to the first bending portion 322, and will not be repeated here to avoid redundancy.

[0055] The elastic band 36 detachably connects the first bracket 32 ​​and the second bracket 34. In this way, when the user wears the wearable device 100 for strenuous activities, the wearable device 100 can be further fixed by the elastic band 36 to prevent the wearable device 100 from loosening or even falling during the strenuous activities. It is understood that in other examples, the elastic band 36 can also be omitted.

[0056] The display 40 includes a Liquid Crystal on Silicon (LCOS) display.

[0057] Please refer again Figure 5 , the light guide component 70 is disposed separately from the display 40. The light guide component 70 includes a first side 71 and a second side 72 opposite to each other. The light guide component 70 is used to guide the light generated by the display 40 and emit it from the first side 71. The light quantity adjustment component 80 is disposed on the second side 72, and the light quantity adjustment component 80 is used to adjust the amount of ambient light incident on the second side 72. The display 40 may be an optical machine, and the light guide component 70 may be a holographic optical waveguide sheet group. The specific forms of the display 40 and the light guide component 70 are not limited here.

[0058] In the relevant augmented reality device, the user can see the content displayed by the augmented reality device in the real scene through the augmented reality device. It can be understood that the ambient light and the light formed by the augmented display device enter the human eye at the same time. If the ambient light brightness is high, the contrast between the display brightness of the augmented reality device and the ambient brightness is too low, and it is difficult for the human eye to see the display content of the augmented reality device clearly. If the ambient light brightness is low, the contrast between the display brightness of the augmented reality device and the ambient brightness is too high, and the display content of the virtual reality device is easy to stimulate people and cause human eye fatigue.

[0059] In order to solve the problem of too high or too low contrast between the display brightness of the augmented reality device and the ambient brightness, the related technology generally adjusts the display brightness of the augmented reality device. However, when the ambient brightness is high, in order to improve the clarity of the picture observed by the human eye, if the display brightness of the augmented reality device is increased, the power consumption of the augmented reality device will be large, and a large amount of heat will be generated, which will affect the user experience.

[0060] In the wearable device 100 of the embodiment of the present application, the light adjustment component 80 can adjust the amount of ambient light incident from the second side 72 and emitted from the first side 71, thereby reducing the impact of the ambient light on the light generated by the display 40 and emitted from the first side 71, which is beneficial for the user to watch the content displayed on the display 40 and improves the user experience.

[0061] It can be understood that when the user wears the wearable device 100, the human eye is located outside the first side 71. Therefore, the light generated by the display 40 can enter the human eye after being emitted from the first side 71, so that the user can observe the image displayed by the display 40.

[0062] The ambient light enters the human eye after passing through the light adjustment component 80, the second side 72 and the first side 71 in sequence, so that the user can see the surrounding objects. Therefore, the light adjustment component 80 of the present application can adjust the ambient light entering the human eye, thereby reducing the influence of the ambient light on the image observed by the human eye.

[0063] The wearable device 100 may further include a light sensor 14 and a collimating component 92. The light sensor 14 is connected to the processor 101. The light sensor 14 is used to detect the ambient brightness, and the processor 101 is used to adjust the transmittance of the light adjustment component 80 according to the ambient brightness, wherein the ambient brightness and the transmittance of the light adjustment component 80 are inversely correlated. In this way, the transmittance of the light adjustment component 80 can be automatically adjusted so that the user can clearly observe the content displayed on the display 40, and the user is not easily fatigued.

[0064] Furthermore, when the ambient brightness increases, the light transmittance of the light quantity adjustment component 80 decreases; when the ambient brightness decreases, the light transmittance of the light quantity adjustment component 80 increases. This makes the contrast of the display screen of the display 40 within the comfortable zone for human eyes, improving the user experience.

[0065] The collimating component 92 is disposed between the display 40 and the light guide component 70, and is used to collimate the light generated by the display 40 and emit it to the light guide component 70. In this way, the collimating component 92 can convert the light generated by the display 40 into parallel light and then enter the light guide component 70, thereby reducing the loss of light.

[0066] The collimating component 92 may include a plurality of lenses, and the plurality of lenses stacked together can collimate the light. The light generated by the display 40 enters the light guide component 70 after passing through the collimating component 92, and the light is emitted from the first side 71 of the light guide component 70 after being totally reflected or diffracted in the light guide component 70.

[0067] The collimating component 92 is disposed between the display 40 and the light guide component 70, and is used to collimate the light generated by the display 40 and emit it to the light guide component 70. In this way, the collimating component 92 can convert the light generated by the display 40 into parallel light and then enter the light guide component 70, thereby reducing the loss of light.

[0068] The collimating component 92 may include a plurality of lenses, and the plurality of lenses stacked together can collimate the light. The light generated by the display 40 enters the light guide component 70 after passing through the collimating component 92, and the light is emitted from the first side 71 of the light guide component 70 after being totally reflected or diffracted in the light guide component 70.

[0069] In this embodiment, the trigger device 1001 is a distance sensor. Figure 2 In the example, the trigger device 1001 can be set at the contact portion 266. Specifically, the trigger device 1001 is set at a position where the contact portion 266 is aligned with the notch 262. The contact portion 266 is located on the side of the light guide component 70 facing the support component 30, and the contact portion 266 is formed with a first through hole 2661 and a second through hole 2662, and the light of the light guide component 70 is emitted from the first through hole 2661 and the second through hole 2662. In this way, the trigger device 1001 is facing the direction of relative movement when the user wears the wearable device 100, so that the trigger device 1001 can detect the relative distance more accurately.

[0070] exist Figure 3 In the example of , the trigger device 1001 is disposed on the first bracket 32. Specifically, the trigger device 1001 is disposed at one end of the first bracket 32 ​​away from the elastic band 36. In this way, the space of the first bracket 32 ​​can be reasonably utilized, and the detection of the relative distance can be achieved at the same time.

[0071] Of course, the trigger device 1001 may also be disposed at other locations of the wearable device 100. The specific location of the trigger device 1001 is not limited herein.

[0072] exist Figure 2 and Figure 3 In the example shown, the number of the triggering device 1001 is 1. It is understandable that the number of the triggering device 1001 may also be 2, 3, 5 or other numbers. The specific number of the triggering device 1001 is not limited here.

[0073] In step S11, the data output by the trigger device 1001 may be a trigger signal, and the distance value may be determined by processing the trigger signal. The data output by the trigger device 1001 may also be a distance value.

[0074] Furthermore, the distance value can be directly used as the value of the relative distance, or the distance value can be processed to obtain the value of the relative distance. For example, the average value of a plurality of distance values ​​measured continuously is used as the value of the relative distance. Or, the distance values ​​with jumps in the plurality of distance values ​​measured continuously are eliminated, and the average value of the remaining distance values ​​is used as the value of the relative distance. This can improve the accuracy of the relative distance.

[0075] The specific form of the data output by the trigger device 1001 is not limited here, and the specific method of determining the relative distance based on the data output by the trigger device 1001 is not limited.

[0076] In addition, the relative distance can be a curve, a plurality of points, or a plurality of values. The specific form of the relative distance is not limited here.

[0077] When the relative distance is a curve, the curve can be placed in a coordinate system, the horizontal axis of the coordinate system can be time, and the vertical axis can be the specific value of the relative distance, such as Figure 6 shown.

[0078] When the relative distance is multiple points, the multiple points can be placed in a coordinate system, the horizontal axis of the coordinate system can be time, and the vertical axis can be the specific value of the relative distance, such as Figure 7 shown.

[0079] When the relative distance is a plurality of values, the plurality of values ​​and the time corresponding to each value may be stored in correspondence, as shown in the following Table 1.

[0080] Table 1

[0081] Time(s) 1 1.2 1.5 1.8 2 2.2 2.5 Relative distance (cm) 5 4.5 3.5 2 0.4 0.4 0.4

[0082] In step S12, “the wearable device is approaching the target object” means that the multiple values ​​of the relative distance gradually decrease. In other words, each value is smaller than the previous value.

[0083] Further, the numerical value used to determine whether the relative distance is decreasing may be 3, 4, 5, 6 or other numbers. The specific number of the numerical values ​​is not limited here.

[0084] In one example, the relative distances are: 5cm, 4.5cm, 4cm, 3cm, 2cm, and multiple values ​​of the relative distances can be determined to gradually decrease. In another example, the relative distances are: 5cm, 4.5cm, 4cm, and multiple values ​​of the relative distances can be determined to gradually decrease. In yet another example, the relative distances are: 5cm, 4.5cm, 4cm, 3cm, and multiple values ​​of the relative distances can be determined to gradually decrease.

[0085] In addition, the first brightness may be a constant brightness. For example, when the relative distance is decreasing, the display is controlled to display at 50% of the second brightness.

[0086] The first brightness may also be a plurality of brightnesses less than the second brightness. The specific brightness value of the first brightness may be determined according to the value of the current relative distance. Further, the specific brightness value of the first brightness may be negatively correlated with the value of the current relative distance. In this way, as the relative distance decreases, the brightness of the display 40 gradually increases, and the user's visual experience becomes smoother.

[0087] For example, as the relative distance decreases, when the relative distance is 5 cm, the first brightness is 50% of the second brightness; the relative distance continues to decrease, when the relative distance is 4 cm, the first brightness is 60% of the second brightness; the relative distance continues to decrease, when the relative distance is 3 cm, the first brightness is 70% of the second brightness.

[0088] In step S13, the "first distance threshold" can be determined in advance through experiments and stored in the wearable device 100. The "first distance threshold" can also be set and modified by the user. The specific source of the "first distance threshold" is not limited here.

[0089] See also Figure 8In one example, the first distance threshold is 0.4cm. The user presses the power button of the wearable device 100 at the 0th second to turn on the wearable device 100. At this time, the trigger device 1001 starts working, and the relative distance can be determined based on the data output by the trigger device 1001. However, since the user is not wearing it, the signal value is relatively stable. The user picks up the wearable device 100 and wears it at the 1st second. At this time, the relative distance gradually decreases, and the display 40 of the wearable device 100 is controlled to display at the first brightness. From 1s to 1.8s, the relative distance decreases from 5cm to 2cm. Thereafter, the relative distance continues to decrease, and after the 2nd second, the relative distance decreases to less than the first distance threshold, that is, less than 0.4cm, and the display 40 of the wearable device 100 is controlled to display at the second brightness.

[0090] In this way, when the user wears the wearable device 100, the user first observes that the display 40 is displayed at a lower brightness. After wearing the wearable device 100, the user observes that the display 40 is displayed at a higher brightness. This is not visually abrupt, has a better effect, and saves power.

[0091] See also Fig. 9 In some embodiments, the control method comprises:

[0092] Step S14: determining, based on the relative distance, a first time duration during which the relative distance is greater than a preset second distance threshold when the wearable device is in a process of moving away from the target object;

[0093] Step S15: When the first duration is greater than a preset first duration threshold, control the display 40 to turn off.

[0094] In some embodiments, the processor 101 is used to determine, based on the relative distance, a first duration when the relative distance is greater than a preset second distance threshold when the wearable device is moving away from a target object; and to control the display 40 to turn off when the first duration is greater than the preset first duration threshold.

[0095] Thus, when the user takes off the wearable device 100, the display 40 is promptly controlled to be turned off, which can save power and extend battery life. In addition, when the first time length when the relative distance is greater than the second distance threshold is greater than the first time length threshold, the display is controlled to be turned off, which can further ensure the accuracy of control.

[0096] It is understandable that when the user is wearing the wearable device 100, the user may take the wearable device 100 off for a short time and put it on again immediately, for example, to wipe off sweat. This will also cause the relative distance to be greater than the second distance threshold. However, the user does not take off the wearable device 100 at this time. The user just makes a slight adjustment and needs to continue using it, and does not need to control the wearable device 100 to turn off.

[0097] The control method of this embodiment controls the display 40 to turn off only when the first duration is greater than the preset first duration threshold, which can avoid the shutdown caused by the user's slight adjustment and ensure that the shutdown is caused by the user taking off the wearable device 100, thereby improving the accuracy of control and improving the user experience.

[0098] In step S14 , the first duration may be recorded when the relative distance is greater than the second distance threshold, and the display 40 may be controlled to be turned off when the first duration is greater than the first duration threshold.

[0099] Similarly, “determining, based on the relative distance, that the wearable device is moving away from the target object” may mean that multiple values ​​of the relative distance gradually increase. In other words, each value is greater than the previous value.

[0100] Further, the numerical value used to determine the relative distance in the process of increasing may be 3, 4, 5, 6 or other numbers. The specific number of the numerical values ​​is not limited here.

[0101] In one example, the relative distances are: 2cm, 3cm, 4cm, 4.5cm, 5cm, and multiple values ​​of the relative distances can be determined to gradually increase. In another example, the relative distances are: 2cm, 3cm, 4cm, 4.5cm, and multiple values ​​of the relative distances can be determined to gradually increase. In yet another example, the relative distances are: 2cm, 3cm, 4cm, and multiple values ​​of the relative distances can be determined to gradually increase.

[0102] See also Fig.10 In one example, the second distance threshold is 1cm, and the first duration threshold is 2s. The user wears the wearable device 100 within 0-1s. After the 1st second, the user takes off the wearable device 100, and the relative distance detected by the trigger device 1001 gradually increases. After the 2nd second, the relative distance is greater than the second distance threshold, that is, greater than 1cm, and the first duration begins to be recorded. Then, the relative distance continues to increase. After the 4th second, the first duration is greater than the first duration threshold, that is, greater than 2s, and the display 40 is controlled to be turned off. In this way, it can be turned off in time according to the relative distance, which can save power and extend battery life.

[0103] See also Fig.11 and Fig.12 In some embodiments, the number of trigger devices 1001 is multiple, and the control method includes:

[0104] Step S112: when the relative distance corresponding to each trigger device 1001 is in the process of decreasing, determining that the wearable device 100 is in the process of approaching the target object;

[0105] Step S13 includes:

[0106] Step S131: When the relative distance corresponding to each trigger device 1001 decreases to less than the first distance threshold, control the display 40 to display at the second brightness.

[0107] In some embodiments, there are multiple trigger devices 1001, and the processor 101 is used to determine that the wearable device 100 is approaching the target object when the relative distance corresponding to each trigger device 1001 is decreasing; and is used to control the display 40 to display at a second brightness when the relative distance corresponding to each trigger device 1001 is reduced to less than the first distance threshold.

[0108] In this way, the accuracy of control can be ensured, and control confusion caused by partial blocking or damage of the trigger device 1001 can be avoided. It is understandable that if there is only one trigger device 1001, the user may grab the part of the wearable device 100 where the trigger device 1001 is located while wearing the wearable device 100, causing the processor 101 to control the display 40 to display at the first brightness according to the data output by the trigger device 1001, which is not consistent with the actual scene.

[0109] In the control method of this embodiment, there are multiple trigger devices 1001, and control is performed according to the relative distance corresponding to each trigger device 1001. This can avoid misjudgment caused by controlling only based on one relative distance corresponding to each trigger device 1001, thereby improving the accuracy of control.

[0110] exist Fig.12 In the example, the number of trigger devices 1001 is 2, namely trigger device 1011 and trigger device 1021. Trigger device 1011 and trigger device 1021 are respectively arranged on both sides of notch 262. The relative distance determined according to the data output by trigger device 1011 is: 5cm, 4.5cm, 4cm, 3cm, 2cm, and is in the process of decreasing. The relative distance determined according to the data output by trigger device 1021 is: 5cm, 4.8cm, 3.7cm, 3.2cm, 2.1cm, and is also in the process of decreasing. It can be determined that when the wearable device 100 is approaching the user, the display 40 can be controlled to display at 50% brightness.

[0111] Next, the relative distance determined according to the data output by the trigger device 1011 is 0.3 cm, which is less than the first distance threshold, that is, less than 0.4 cm. The relative distance determined according to the data output by the trigger device 1021 is 0.35 cm, which is also less than the first distance threshold, that is, less than 0.4 cm. It can be determined that the relative distance is less than the first distance threshold, so that the display 40 is controlled to display at 100% brightness.

[0112] It can be understood that in other examples, the number of the multiple trigger devices 1001 can be 3, 4, 5 or other numbers, and the multiple trigger devices 1001 can be set at other positions of the wearable device 100. The specific number and specific positions of the multiple trigger devices 1001 are not limited here.

[0113] See also Fig.13 In some embodiments, after step S12, the control method includes:

[0114] Step S14: determining a second time duration during which the relative distance corresponding to each trigger device 1001 decreases to be less than the first distance threshold;

[0115] Step S15: When the second time duration is greater than a preset second time duration threshold, the control part triggers the device 1001 to be turned off.

[0116] In some embodiments, the processor 101 is used to determine that the relative distance corresponding to each trigger device 1001 is reduced to a second time length that is less than a first distance threshold; and is used to control some trigger devices 1001 to turn off when the second time length is greater than a preset second time length threshold.

[0117] In this way, while ensuring that some trigger devices 1001 work normally, energy consumption can be reduced and electricity can be saved by turning off some trigger devices 1001. In addition, when the second time length is greater than the preset second time length threshold, some trigger devices 1001 are controlled to be turned off, which can ensure that the trigger device 1001 is turned off only after the wearing state of the wearable device 100 is stable, thereby improving the accuracy of control.

[0118] It can be understood that when the relative distance corresponding to each trigger device 1001 is reduced to a second time length less than the first distance threshold and greater than the second time length threshold, it can be determined that the wearable device 100 is worn. Since the display 40 is already displayed at the second brightness at this time, it is not necessary for all trigger devices 1001 to be turned on to avoid misjudgment. Therefore, some trigger devices 1001 can be turned off to save power, and the trigger devices 1001 that remain turned on can continue to monitor the relative distance so as to respond in time when the user takes off the wearable device 100.

[0119] In step S14 , the timing of the second duration may be started when the relative distance corresponding to each trigger device 1001 decreases to be smaller than the first distance threshold.

[0120] In step S15, the second duration threshold may be 4s, 5s, 8s, 10s or other values. The specific value of the second duration threshold is not limited here. The second duration threshold may be the same as the first duration threshold, or may be different from the first duration threshold.

[0121] In addition, controlling some of the trigger devices 1001 to be turned off means that not all of the trigger devices 1001 are turned off. Specifically, one trigger device 1001 may be turned on, and the rest of the trigger devices 1001 may be turned off; or multiple trigger devices 1001 may be turned on, and the rest of the trigger devices 1001 may be turned off. The specific situation of controlling some of the trigger devices 1001 to be turned off is not limited here.

[0122] In addition, the trigger device 1001 to be turned off can be determined according to the working time of each trigger device 1001. In this embodiment, the trigger device 1001 with the shortest working time can be kept turned on, and the other trigger devices can be turned off. In this way, the trigger devices 1001 can be used evenly.

[0123] It can be understood that when the user presses the power button of the wearable device 100 and the wearable device 100 is powered on, the working time of each trigger device 1001 can be calculated. During use, each trigger device 1001 may be turned off, resulting in interruption of the working time, thereby making the working time of each trigger device 1001 inconsistent. Based on this, the trigger device 1001 to be turned off can be determined according to the working time of each trigger device 1001.

[0124] In addition, the trigger device to be turned off can be determined according to the power of each trigger device 1001. In this embodiment, the trigger device 1001 with the lowest power can be kept turned on, and the other trigger devices can be turned off. In this way, power can be further saved.

[0125] Of course, the trigger device 1001 to be closed can also be determined randomly. The specific method of determining the trigger device 1001 to be closed is not limited here.

[0126] See also Fig.14 In some embodiments, after step S15, the control method includes:

[0127] Step S16: determining the relative distance according to the data output by the activated trigger device 1001;

[0128] Step S17: when each relative distance is greater than a preset second distance threshold, turning on the closed trigger device 1001;

[0129] Step S18: When the relative distance corresponding to each trigger device 1001 is greater than the second distance threshold, control the display 40 to turn off.

[0130] In some embodiments, the processor 101 is used to determine the relative distance based on the data output by the turned-on trigger device 1001; and is used to turn on the turned-off trigger device 1001 when each relative distance is greater than a preset second distance threshold; and is used to control the display 40 to turn off when the relative distance corresponding to each trigger device 1001 is greater than the second distance threshold.

[0131] In this way, the accuracy of control can be guaranteed, and the control confusion caused by the partial blocking or damage of the trigger device 1001 can be avoided. It can be understood that if the relative distance is determined only based on the data output by the trigger device 1001 that remains turned on, and when each relative distance is greater than the second distance threshold, the display 40 is controlled to be turned off. When the trigger device 1001 that is turned on is damaged or falls, it may be determined based on the relative distance that the wearable device 100 has been taken off, thereby controlling the display 40 to be turned off. However, in fact, the wearable device 100 is not taken off, resulting in the control not being consistent with the actual scene.

[0132] In the present embodiment, when each relative distance is greater than a preset second distance threshold, the closed trigger device 1001 is turned on, and when the relative distance corresponding to each trigger device 1001 is greater than the second distance threshold, the display 40 is controlled to be turned off, so that all the trigger devices 1001 participate in the collection of distance data, thereby reducing the probability of the control not being consistent with the actual scene, thereby improving the accuracy of the control.

[0133] In an example, see again Fig.12 , the number of trigger devices 1001 is 2, namely trigger device 1011 and trigger device 1021. The second duration threshold is 10s, and after the display 40 is controlled to display at 100% brightness for 10s, trigger device 1021 is turned off, and trigger device 1011 remains on.

[0134] The second distance threshold is 1 cm. After a period of time, the user takes off the wearable device 100, and the relative distance determined by the data output by the trigger device 1011 is 1.1 cm, which is greater than the second distance threshold, so the trigger device 1021 is turned on. The relative distance determined by the data output by the trigger device 1011 is 1.2 cm, which is also greater than the second distance threshold, so the display 40 is controlled to be turned off.

[0135] The processor 101 may be an application processor (AP). The first duration threshold, the second duration threshold, the first distance threshold, and the second distance threshold may all be stored in a register of the processor 101. Fig.15The trigger device 1001 may send the output data to the processor 101. After determining the control instruction for the display 40, the processor 101 may send the control instruction to the display 40, so that the display 40 turns on or off according to the control instruction. The processor 101 may also send a closing instruction and an opening instruction to the trigger device 1001.

[0136] The non-volatile computer-readable storage medium containing computer-executable instructions in the embodiments of the present application, when the computer-executable instructions are executed by one or more processors 101, enables the processor 101 to execute the above control method.

[0137] For example, the following steps are performed: Step S11: determining the relative distance according to the data output by the trigger device 1001 of the wearable device 100, where the relative distance is the distance between the trigger device 1001 and the target object; Step S12: controlling the display 40 of the wearable device 100 to display at a first brightness when the wearable device 100 is approaching the target object according to the relative distance; Step S13: when the relative distance is reduced to less than a preset first distance threshold, controlling the display 40 to display at a second brightness, where the second brightness is greater than the first brightness.

[0138] In the storage medium of the embodiment of the present application, when the user puts on the wearable device 100, the display 40 first displays at a lower first brightness, and then displays at a higher second brightness after the user puts on the wearable device 100. This can save power to extend battery life, and can also transition through the first brightness before the display 40 displays at the second brightness to improve visual experience, which is conducive to improving user experience.

The wearable device 100 includes a processor 101, a memory 102 (for example, a non-volatile storage medium), an internal memory 103, a display device 104, and an input device 105 connected via a system bus 109. Among them, the memory 102 of the wearable device 100 stores an operating system and computer-readable instructions. The computer-readable instructions can be executed by the processor 101 to implement the control method of any of the above-mentioned embodiments. The display device 104 may include a display 40.

[0140] The processor 101 can be used to provide computing and control capabilities to support the operation of the entire wearable device 100. The internal memory 103 of the wearable device 100 provides an environment for the operation of computer-readable instructions in the memory 102. The input device 105 can also be a button, trackball or touchpad provided on the housing of the wearable device 100, or an external keyboard, touchpad or mouse.
