Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.

Referring to fig. 1, 2 and 3, an embodiment of the present application provides a control method. The control method is used for the wearable device 100. The control method comprises the following steps:

step S11: determining a relative distance according to data output by a trigger 1001 of the wearable device 100, wherein the relative distance is a distance between the trigger 1001 and a target object;

step S12: when the wearable device 100 is determined to be in the process of approaching the target object according to the relative distance, controlling the display 40 of the wearable device 100 to display at a first brightness;

step S13: and when the relative distance is reduced to be smaller than the preset first distance threshold value, controlling the display 40 to display at a second brightness, wherein the second brightness is larger than the first brightness.

Referring to fig. 4, the present embodiment provides a wearable device 100. The wearable device 100 comprises a processor 101 and a trigger 1001, the processor 101 is connected with the trigger 1001, and the processor 101 is used for determining a relative distance according to data output by the trigger 1001 of the wearable device 100, wherein the relative distance is a distance between the wearable device 100 and a target object; and the display 40 is used for controlling the wearable device 100 to display at a first brightness when the wearable device 100 is determined to be in the process of approaching the target object according to the relative distance; and for controlling the display 40 to display at a second brightness when the relative distance decreases to less than a preset first distance threshold, the second brightness being greater than the first brightness.

According to the control method and the wearable device 100 in the embodiment of the application, when a user wears the wearable device 100, the display 40 displays at a first lower brightness, and displays at a second higher brightness after the user wears the wearable device 100, so that electric quantity can be saved to prolong cruising, and transition can be performed through the first brightness before the display 40 displays at the second brightness to improve visual perception and improve user experience.

In order to save electric energy, the related art generally turns off the display by a button provided on the wearable device body or the handle, or sets an auto-off time to control an operating state of the display, for example, turns on an auto-off timer when no operation is detected. However, the operation of the key is cumbersome, resulting in a poor user experience. The waiting time of automatic closing is not flexible, and the electric quantity is easy to waste.

Specifically, in one example, because the key operation is cumbersome, the user forgets the key after using the wearable device, causing the display to continue to light for a period of time, even until the power is completely used up, and the display is turned off.

In another example, the user takes off the wearable device halfway during the use of the wearable device, and the user continues to use the wearable device later, so that the button is not turned off, and the halfway taken off time display is still in a working state, which wastes electricity.

In yet another example, the auto-off time is set too short to automatically turn off the display during the user-operated gap, affecting the user experience.

In another example, the set auto-off time is too long, and the display still works normally for a long time after the user takes off the wearable device, resulting in waste of power.

The control method of the embodiment of the application does not need other triggering actions except for wearing of the user, does not need to set the automatic closing time, is simple, convenient and flexible, and can improve user experience and save electric quantity to prolong the endurance time. Moreover, in the process that the user wears the wearable device 100, the distance between the trigger device 1001 and the target object is gradually decreased, the display 40 is controlled to display at the first brightness, and when the distance between the trigger device 1001 and the target object is decreased to be smaller than the preset first distance threshold, the display is controlled to display at the second brightness, so that the brightness transition is formed, the visual perception of the user is smoother, and the improvement of the user experience is facilitated.

In addition, controlling the display 40 to display at the first brightness may also save power while prompting the user. It is understood that controlling the display 40 to display at a first brightness during the wearing of the wearable device 100 by the user may prompt the user that the user's motion has been sensed by the wearable device 100 and continuing to wear the display 40 may display at a second brightness. In this way, the user can know the current state of the wearable device 100 during wearing, and does not need to wait until the wearable device 100 is completely worn, so that corresponding treatment can be timely performed when the wearable device 100 is damaged or is not powered on.

Specifically, the wearable device 100 is, for example, a Head Mounted Display (HMD), and the HMD may transmit an optical signal to the eyes of the user through cooperation of a computing system and an optical system after the user wears the HMD, so as to achieve different effects, such as Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR). Wearable device 100 may also be a hand-worn device such as a smart watch, smart bracelet, or the like. The specific form of the wearable device 100 is not limited herein.

For convenience of understanding, the wearable device 100 of the embodiment of the present application is described in detail with a head-mounted display device as an example. The wearable device 100 may be an integrated head-mounted display device or a split head-mounted display device.

Referring to fig. 3 and 5, an electronic device 100 according to an embodiment of the present disclosure includes a housing 20, a supporting member 30, a display 40, a light guide member 70, and a light amount adjusting member 80.

The housing 20 is an external component of the wearable device 100, and serves to protect and fix an internal component of the wearable device 100. The housing 20 encloses the internal components and prevents direct damage to these components from external factors.

Specifically, in the present embodiment, the case 20 may be used to fix at least one of the display 40, the light guide member 70, and the triggering device 1001. In the example of fig. 2, the case 20 is formed with a housing chamber 22, and the display 40, the light guide member 70, and the light amount adjustment member 80 are housed in the housing chamber 22.

The housing 20 further includes a housing top wall 24, a housing bottom wall 26, and housing side walls 28. The middle of the housing bottom wall 26 forms a notch 262 toward the housing top wall 24. Alternatively, the housing 20 is generally "B" shaped. When the user wears the wearable device 100, the wearable device 100 can be erected on the bridge of the nose of the user through the notch 262, so that the stability of the wearable device 100 can be guaranteed, and the wearing comfort of the user can be guaranteed.

The wearable device 100 can further include a nose piece 264 disposed in the notch 262, the nose piece 264 being removably coupled to the housing bottom wall 26. Therefore, the user can wear the clothes more comfortably, and the user experience is improved. In addition, the nose frame 264 can adapt to different nose bridge heights by the adjusting device, thereby improving the adaptability of the wearable device 100. The nose piece 264 may also include different models, and the user may select different models of nose pieces 264 to assemble to the wearable device 100 according to his or her needs.

In addition, the housing 20 may be formed by machining an aluminum alloy through a Computer Numerical Control (CNC), and may be injection molded using Polycarbonate (PC) or PC and Acrylonitrile Butadiene Styrene (ABS). The specific manner of manufacturing and the specific material of the housing 20 are not limited herein.

The support member 30 is used to support the wearable device 100. The wearable device 100 may be fixed on the head of the user by the support member 30 when the user wears the wearable device 100. In the example of fig. 2, the support member 30 includes a first bracket 32, a second bracket 34, and an elastic band 36.

The first bracket 32 and the second bracket 34 are symmetrically disposed about the notch 262. Specifically, the first stand 32 and the second stand 34 are rotatably provided at the edge of the housing 20, and the first stand 32 and the second stand 34 can be stacked adjacent to the housing 20 for storage when the user does not need to use the wearable device 100. When the user needs to use the wearable device 100, the first stand 32 and the second stand 34 can be unfolded to realize the function of the first stand 32 and the second stand 34.

The first bracket 32 has a first bent portion 322 formed at an end thereof away from the housing 20, and the first bent portion 322 is bent toward the bottom wall 26 of the housing. In this way, when the user wears the wearable device 100, the first bending part 322 can be erected on the ear of the user, so that the wearable device 100 is not easy to slip off.

Similarly, the end of the second bracket 34 away from the housing 20 is formed with a second bent portion 342. The explanation and description of the second bending portion 342 can refer to the first bending portion 322, and are not repeated herein for avoiding redundancy.

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 to perform strenuous activities, the wearable device 100 can be further fixed by the elastic band 36, and the wearable device 100 is prevented from loosening or even falling off during strenuous activities. It is understood that in other examples, the elastic band 36 may be omitted.

The display 40 comprises a Silicon-based Liquid Crystal display (LCOS).

Referring to fig. 5 again, the light guide member 70 is disposed apart from the display 40. The light guide member 70 includes first and second opposing

sides

71 and 72. The light guide member 70 is for guiding light generated from the display 40 and emitting the light from the first side 71. The light amount adjustment member 80 is disposed on the second side 72, and the light amount adjustment member 80 is used to adjust the amount of ambient light incident to the second side 72. The display 40 may be an optical engine and the light guide 70 may be a set of holographic optical waveguides. The specific form of the display 40 and the light guide member 70 is not limited herein.

In a related augmented reality device, a user can see content displayed by the augmented reality device in a real scene through the augmented reality device. It can be understood that the light formed by the ambient light and the augmented reality device enters human eyes at the same time, if the light brightness of the environment is higher, the contrast between the display brightness of the augmented reality device and the ambient brightness is too low, and the display content of the augmented reality device is difficult to see by the human eyes. If the light brightness of the environment is low, the contrast between the display brightness of the augmented reality device and the environment brightness is too high, and the display content of the virtual reality device easily stimulates people to cause eye fatigue.

In order to solve the problem that the contrast between the display brightness of the augmented reality device and the ambient brightness is too high or too low, the related art generally adjusts the display brightness of the augmented reality device. However, when the ambient brightness is high, if the display brightness of the augmented reality device is increased in order to improve the image clarity observed by human eyes, the power consumption of the augmented reality device is increased, and a large amount of heat is generated to affect the user experience.

In the wearable device 100 according to the embodiment of the present application, the light quantity adjusting component 80 can adjust the quantity of the ambient light entering from the second side 72 and exiting from the first side 71, so that the influence of the quantity of the ambient light on the light generated by the display 40 and exiting from the first side 71 can be reduced, the user can watch the content displayed by the display 40, and the user experience can be improved.

It will be appreciated that when the user is wearing the device 100, the eye is outside the first side 71, and therefore light generated by the display 40 exits the first side 71 and may enter the eye, thereby allowing the user to view the image displayed by the display 40.

The ambient light enters the human eye after passing through the light amount adjustment member 80, the second side 72, and the first side 71 in this order, so that the user can see the environmental matters. Therefore, the light amount adjustment section 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.

The wearable device 100 may also 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 for detecting the ambient brightness, and the processor 101 is used for adjusting the light transmittance of the light quantity adjusting part 80 according to the ambient brightness, wherein the ambient brightness and the light transmittance of the light quantity adjusting part 80 are in an inverse correlation relationship. The light transmittance of the light amount adjustment member 80 can thus be automatically adjusted so that the user can clearly observe what is displayed on the display 40, and the user is less fatigued.

Further, when the ambient brightness increases, the light transmittance of the light amount adjusting member 80 decreases; when the ambient brightness decreases, the light transmittance of the light amount adjustment member 80 increases. This allows the contrast of the display image of the display 40 to be in a comfortable region for human eyes to view, thereby improving the user experience.

The collimating member 92 is disposed between the display 40 and the light guide 70, and the collimating member 92 is used for collimating the light generated by the display 40 and emitting the collimated light to the light guide 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, so that the loss of the light can be reduced.

The collimating component 92 may include a plurality of lenses that, when added together, may collimate the light. The light generated from the display 40 enters the light guide member 70 after passing through the collimating member 92, and the light is totally reflected or diffracted in the light guide member 70 and then exits from the first side 71 of the light guide member 70.

In the present embodiment, the trigger 1001 is a distance sensor. In the example of fig. 2, the trigger 1001 may be provided at the contact portion 266. Specifically, trigger 1001 is disposed at a location where contact 266 aligns with notch 262. Contact portion 266 is located on the side of light guide member 70 facing support member 30, and contact portion 266 is formed with first through hole 2661 and second through hole 2662, and light of light guide member 70 is emitted from first through hole 2661 and second through hole 2662. In this way, the trigger 1001 faces the direction of relative movement when the user wears the wearable device 100, so that the detection of the relative distance by the trigger 1001 is more accurate.

In the example of fig. 3, the triggering device 1001 is provided at the first carriage 32. Specifically, the trigger 1001 is disposed at an end of the first bracket 32 facing 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 realized at the same time.

Of course, the triggering device 1001 may be disposed at other positions of the wearable device 100. The specific position of the triggering device 1001 is not limited herein.

In the example shown in fig. 2 and 3, the number of the triggering devices 1001 is 1. It is understood that the number of triggering devices 1001 may also be 2, 3, 5, or other numbers. The number of trigger devices 1001 is not limited to a specific number.

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

Further, the distance value can be directly used as a numerical value of the relative distance, or the distance value can be processed to obtain a numerical value of the relative distance. For example, an average value of a plurality of distance values measured in succession is taken as the numerical value of the relative distance. Or eliminating jump distance values in a plurality of continuously measured distance values, and taking the average value of the rest distance values as the numerical value of the relative distance. This may improve the accuracy of the relative distance.

The specific form of data output by the trigger 1001 is not limited, nor is the specific manner in which the relative distance is determined from the data output by the trigger 1001.

In addition, the relative distance may be a curve, a plurality of points, a plurality of values. The specific form of the relative distance is not limited herein.

When the relative distance is a curve, the curve may be placed in a coordinate system, and the horizontal axis of the coordinate system may be time and the vertical axis may be a specific value of the relative distance, as shown in fig. 6.

When the relative distance is a plurality of points, the plurality of points may be placed in a coordinate system, and the horizontal axis of the coordinate system may be time and the vertical axis may be a specific value of the relative distance, as shown in fig. 7.

When the relative distance is a plurality of values, the plurality of values and the time corresponding to each value can be correspondingly stored. As shown in table 1 below.

TABLE 1

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

In step S12, "the wearable device is approaching the target object" means that the plurality of values of the relative distance gradually decrease. In other words, each value is smaller than the previous value.

Further, the values used to determine the relative distance in the process of decreasing may be 3, 4, 5, 6, or other numbers. The specific number of numerical values is not limited herein.

In one example, the relative distances are: 5cm, 4.5cm, 4cm, 3cm, 2cm, a plurality of values determining the relative distance are gradually reduced. In another example, the relative distances are: 5cm, 4.5cm, 4cm, a plurality of values determining the relative distance are progressively reduced. In yet another example, the relative distance is: 5cm, 4.5cm, 4cm, 3cm, a plurality of values determining the relative distance are gradually reduced.

In addition, the first luminance may be a constant luminance. For example, when the relative distance is in the process of decreasing, the display is controlled to display at a luminance of 50% of the second luminance.

The first luminance may also be a plurality of luminances smaller than the second luminance. The specific brightness value of the first brightness may be determined according to the current value of the relative distance. Further, the specific brightness value of the first brightness may be inversely related to the current relative distance value. Thus, as the relative distance decreases, the brightness of the display 40 gradually increases and the user's visual perception becomes smoother.

For example, in the process of decreasing the relative distance, at a relative distance of 5cm, the first luminance is 50% of the second luminance; the relative distance is continuously reduced, and when the relative distance is 4cm, the first brightness is 60% of the second brightness; the relative distance continues to decrease, and at a relative distance of 3cm, the first luminance is 70% of the second luminance.

In step S13, the "first distance threshold" may be determined in advance through experiments and stored in the wearable device 100. The "first distance threshold" may also be set and modified at the discretion of the user. The specific source of the "first distance threshold" is not limited herein.

Referring to FIG. 8, in one example, the first distance threshold is 0.4 cm. When the user presses the power key of the wearable device 100 at the 0 th s to turn on the wearable device 100, the trigger device 1001 starts to operate, and the relative distance can be determined according to the data output by the trigger device 1001. But the signal value is more stable because the user does not wear the device. When the user picks up the wearable device 100 and wears the wearable device at the 1 st s, the relative distance gradually decreases, and the display 40 of the wearable device 100 is controlled to display at the first brightness. At 1s-1.8s, the relative distance decreases from 5cm to 2 cm. Thereafter, the relative distance continues to decrease, and after 2s, the relative distance decreases to be 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.

Thus, when the user wears the wearable device 100, the user first observes the display 40 to display at a lower brightness, and after the user wears the wearable device 100, the user observes the display 40 to display at a higher brightness, so that the display is visually unobtrusive, the effect is better, and the power is saved.

Referring to fig. 9, in some embodiments, the control method includes:

step S14: determining a first duration of which the relative distance is greater than a preset second distance threshold when the wearable device is far away from the target object according to the relative distance;

step S15: and controlling the display 40 to be closed when the first time length is larger than a preset first time length threshold value.

In some embodiments, the processor 101 is configured to determine, according to the relative distance, a first duration that the relative distance is greater than a preset second distance threshold when the wearable device is in a process of being away from the target object; and for controlling the display 40 to be turned off when the first time length is greater than a preset first time length threshold.

Thus, when the user takes off the wearable device 100, the display 40 is controlled to be turned off in time, and the electric quantity can be saved to prolong the endurance. In addition, when the first duration that the relative distance is greater than the second distance threshold is greater than the first duration threshold, the display is controlled to be closed, and the accuracy of control can be further ensured.

It is understood that during wearing of the wearable device 100, it is possible for the user to take the wearable device 100 off for a short time and put it on immediately, for example, to wipe sweat. This also results in the relative distance being greater than the second distance threshold. However, at this time, the user does not take off the wearable device 100, and the user only needs to make a slight adjustment, and needs to continue to use the wearable device, and does not need to control the wearable device 100 to be turned off.

In the control method of the embodiment, the display 40 is controlled to be turned off only when the first duration is greater than the preset first duration threshold, so that turning off caused by a slight adjustment action of the user can be avoided, and turning off caused by an action of taking off the wearable device 100 by the user is ensured, thereby improving the accuracy of control and improving user experience.

In step S14, the recording of the first duration may be started 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.

Similarly, "determining that the wearable device is away from the target object based on the relative distance" may refer to a plurality of values of the relative distance increasing gradually. In other words, each value is greater than the previous value.

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

In one example, the relative distances are: 2cm, 3cm, 4cm, 4.5cm, 5cm, a plurality of values that can determine the relative distance gradually increase. In another example, where the relative distance is 2cm, 3cm, 4cm, 4.5cm, a plurality of values of the relative distance may be determined to be increasing. In yet another example, the relative distance is: 2cm, 3cm, 4cm, a plurality of values determining the relative distance are gradually increased.

Referring to fig. 10, in one example, the second distance threshold is 1cm and the first duration threshold is 2 s. The user wears the wearable device 100 within 0-1s, after the 1 st s, the user takes off the wearable device 100, the relative distance detected by the trigger 1001 becomes gradually larger, and after the 2 nd s, the relative distance is larger than the second distance threshold, namely larger than 1cm, and then the recording of the first duration is started. Then, the relative distance continues to increase, and after 4s, the first duration is greater than the first duration threshold, i.e., greater than 2s, and the display 40 is controlled to turn off. Therefore, the system can be closed in time according to the relative distance, and the electric quantity can be saved to prolong the endurance.

Referring to fig. 11 and 12, in some embodiments, the number of the triggering devices 1001 is multiple, and the control method includes:

step S112: when the relative distance corresponding to each trigger 1001 is in the process of decreasing, it is determined that the wearable device 100 is in the process of approaching the target object;

step S13 includes:

step S131: when the relative distance corresponding to each trigger 1001 decreases to less than the first distance threshold, the display 40 is controlled to display at a second brightness.

In some embodiments, the number of the triggering devices 1001 is plural, and the processor 101 is configured to determine that the wearable device 100 is in the process of approaching the target object when the relative distance corresponding to each triggering device 1001 is in the process of decreasing; and for controlling the display 40 to display at a second brightness when the relative distance corresponding to each trigger 1001 decreases to less than the first distance threshold.

Therefore, the accuracy of control can be ensured, and control confusion caused by shielding or damaging part of the trigger device 1001 is avoided. It is understood that if the number of the triggering devices 1001 is only one, the user may grasp the portion of the wearable device 100 where the triggering devices 1001 are located during wearing the wearable device 100, and the processor 101 controls the display 40 to display at the first brightness according to the data output by the triggering devices 1001, which does not correspond to the real scene.

In contrast, in the control method of the present embodiment, the number of the trigger devices 1001 is plural, and the control is performed based on the relative distance corresponding to each trigger device 1001, so that it is possible to avoid erroneous determination caused by the control based on only one relative distance corresponding to each trigger device 1001, thereby improving the accuracy of the control.

In the example of fig. 12, the number of triggering devices 1001 is 2, namely triggering device 1011 and triggering device 1021. The trigger 1011 and the trigger 1021 are disposed on two sides of the gap 262. The relative distance determined from the data output by the triggering device 1011 is: 5cm, 4.5cm, 4cm, 3cm, 2cm, in the reduction process. The relative distance determined according to the data output by the trigger device 1021 is: 5cm, 4.8cm, 3.7cm, 3.2cm, 2.1cm, also in the process of reduction. It may be determined that the wearable device 100 is in the process of being in proximity to the user and may control the display 40 to display at 50% brightness.

The relative distance determined from the data output by the triggering device 1011 is then 0.3cm, less than the first distance threshold, i.e. less than 0.4 cm. The relative distance determined from the data output by the triggering device 1021 is 0.35cm, which is also less than the first distance threshold, i.e. less than 0.4 cm. It may be determined that the relative distance is less than the first distance threshold and thereby control the display 40 to display at 100% brightness.

It is understood that in other examples, the number of the plurality of triggering devices 1001 may be 3, 4, 5 or other numbers, and the plurality of triggering devices 1001 may be disposed at other positions of the wearable device 100. The specific number and specific positions of the plurality of triggering devices 1001 are not limited herein.

Referring to fig. 13, in some embodiments, after step S12, the control method includes:

step S14: determining that the relative distance corresponding to each trigger 1001 decreases to a second duration less than the first distance threshold;

step S15: when the second time length is greater than a preset second time length threshold, the control part triggers the device 1001 to turn off.

In some embodiments, the processor 101 is configured to determine that the relative distance corresponding to each trigger 1001 decreases to a second length of time that is less than the first distance threshold; and for controlling the partial trigger 1001 to turn off when the second duration is greater than a preset second duration threshold.

Therefore, when it is ensured that a part of the trigger device 1001 works normally, the energy consumption can be reduced by closing the part of the trigger device 1001, and the electric quantity is saved. In addition, when the second duration is greater than the preset second duration threshold, part of the trigger device 1001 is controlled to be turned off, so that it can be ensured that the trigger device 1001 is turned off after the wearing state of the wearing device 100 is stable, and the accuracy of control is improved.

It is understood that when the relative distance corresponding to each trigger 1001 decreases to be less than the first distance threshold for a second time period greater than the second time period threshold, the wearing state of the wearing apparatus 100 may be determined as worn, and since the display 40 is already displayed at the second brightness at this time, all the triggers 1001 are not required to be turned on to avoid misjudgment. Thus, portions of the trigger 1001 may be turned off to conserve power, and the trigger 1001 that remains turned on may continue to monitor relative distance for timely response when the user takes off the wearable device 100.

In step S14, the timing of the second length of time may be started when the relative distance corresponding to each trigger 1001 decreases to less than the first distance threshold.

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 herein. The second duration threshold may be the same as the first duration threshold or may be different from the first duration threshold.

In addition, the control section triggering device 1001 is closed, which means that the plurality of triggering devices 1001 are not all closed. Specifically, 1 trigger 1001 may be kept on, the remaining triggers 1001 off; it is also possible to keep a plurality of the triggering devices 1001 on and the remaining triggering devices 1001 off. The specific case where the control section triggering device 1001 is turned off is not limited herein.

In addition, the triggering devices 1001 to be turned off may be determined according to the operation time period of each triggering device 1001. In the present embodiment, the trigger 1001 having the smallest operating time period may be kept on, and the remaining triggers may be turned off. In this manner, the trigger 1001 may be used in a balanced manner.

It is understood that after the user presses the power key of the wearable device 100 and the wearable device 100 is powered on, the calculation of the working time length of each triggering device 1001 may be started, and during the use process, each triggering device 1001 may be turned off, which may cause the interruption of the working time length, so that the working time length of each triggering device 1001 is inconsistent. Based on this, the triggering devices 1001 to be turned off may be determined according to the operation time period of each triggering device 1001.

In addition, the triggering device to be turned off may be determined according to the power of each triggering device 1001. In this embodiment, the trigger 1001 with the lowest power may be kept on, and the remaining triggers may be turned off. Thus, the electric quantity can be further saved.

Of course, the trigger 1001 to be turned off may be determined randomly. The specific manner of determining the trigger 1001 to be turned off is not limited herein.

Referring to fig. 14, in some embodiments, after step S15, the control method includes:

step S16: determining a relative distance according to data output by the activated triggering device 1001;

step S17: when each relative distance is greater than a preset second distance threshold, turning on the turned-off triggering device 1001;

step S18: when the relative distance corresponding to each trigger 1001 is greater than the second distance threshold, the display 40 is controlled to be turned off.

In some embodiments, processor 101 is configured to determine the relative distance based on data output by the enabled trigger 1001; and a trigger 1001 for turning on the turned-off trigger when each relative distance is greater than a preset second distance threshold; and for controlling the display 40 to turn off when the relative distance corresponding to each trigger 1001 is greater than a second distance threshold.

Therefore, the accuracy of control can be ensured, and control confusion caused by shielding or damaging part of the trigger device 1001 is avoided. It will be appreciated that if the relative distances are determined solely from the data output by the keep-alive trigger 1001, the display 40 is controlled to be off when each relative distance is greater than the second distance threshold. When the triggering device 1001 including the turn-on is damaged or falls, it may be determined that the wearing apparatus 100 has been taken off according to the relative distance, thereby controlling the display 40 to be turned off. In practice, the wearable device 100 is not detached, resulting in a control mismatch with the actual scene.

In the present embodiment, when each relative distance is greater than the preset second distance threshold, the closed triggering device 1001 is turned on, and when the relative distance corresponding to each triggering device 1001 is greater than the second distance threshold, the display 40 is controlled to be closed, so that all triggering devices 1001 participate in the acquisition of distance data, thereby reducing the probability that the control does not conform to the actual scene, and further improving the accuracy of the control.

In one example, referring again to fig. 12, the number of the triggering devices 1001 is 2, i.e. the triggering device 1011 and the triggering device 1021. The second time threshold is 10s, and after the display 40 is controlled to display at 100% brightness for the 10 th s, the triggering device 1021 is turned off, and the triggering device 1011 remains on.

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

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 registers of the processor 101. Referring to fig. 15, the triggering device 1001 may send the output data to the processor 101, and after determining the control command for the display 40, the processor 101 may send the control command to the display 40, so that the display 40 is turned on or off according to the control command. The processor 101 may also send a close command and an open command to the triggering device 1001.

The storage medium of this application embodiment, the in-process of wearing equipment 100 is worn at the user, and display 40 shows with lower first luminance earlier, after the user wore wearing equipment 100, just shows with higher second luminance, so both can practice thrift the electric quantity in order to prolong the continuation of the journey, can pass through first luminance again before display 40 shows with second luminance to improve visual perception, be favorable to improving user experience.
