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 and 2, 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 S12: acquiring a signal curve output by a trigger 1001 of the wearable device 100;

step S14: determining fluctuation information of the signal curve;

step S17: when the fluctuation information meets a preset fluctuation condition, determining a target operation state of the wearable device 100 according to the signal curve;

step S18: and controlling the wearable device 100 to switch to the target running state.

Referring to fig. 3, the present embodiment provides a wearable device 100. The wearable device 100 comprises a processor 101 and a trigger 1001, wherein the processor 101 is connected with the trigger 1001, and the processor 101 is used for acquiring a signal curve output by the trigger 1001 of the wearable device 100; and fluctuation information for determining the signal profile; and is used for determining the target running state of the wearable device 100 according to the signal curve when the fluctuation information meets the preset fluctuation condition; and for controlling the wearable device 100 to switch to the target operational state.

According to the control method and the wearable device 100, the target running state of the wearable device 100 is determined according to the signal curve output by the trigger device 1001, so that the wearable device 100 is controlled to be switched to the target running state, other trigger actions except wearing of a user are not needed, simplicity and convenience are achieved, flexibility is achieved, user experience can be improved, and electric quantity can be saved. In addition, when the fluctuation information meets the preset fluctuation condition, the target running state is determined according to the signal curve, so that false triggering can be prevented, and the accuracy of control is improved.

In order to save electric energy, the related art usually controls the working state of the display screen by setting a screen-turning-off button on the wearable device body or the handle to turn off the screen or setting automatic screen-turning-off time, for example, starting automatic screen-turning-off timing when no operation is detected. However, the operation of pressing the key to turn the screen is cumbersome, resulting in poor user experience. The waiting time of automatic screen turning is not flexible, and the electricity 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, the display is not 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 user does not press the key to turn off the screen, and the display is still in a working state during the halfway taking off, which wastes electricity.

In yet another example, the automatic screen-off time is set too short, automatically turning off the screen during the user-operated gap, which affects the user experience.

In another example, the automatic screen-off time is set to be too long, and after the user takes off the wearable device, the display still works normally for a longer time, which results in waste of electric quantity.

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 automatic screen-off time, is simple, convenient and flexible, and can improve user experience and save electric quantity. Moreover, the user does not need to perform identity authentication, the compatibility is good, the user does not need to check the current display state of the wearable device 100, the display 40 of the wearable device is normally displayed when the user wears the wearable device, and the user can take off the display 40 of the wearable device, so that the electric quantity is saved.

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. 2 and 4, 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.

Referring to fig. 5, the wearable device 100 may further include a nose piece 264 disposed in the gap 262, wherein the nose piece 264 is detachably connected to the bottom wall 26 of the shell. Therefore, the user can wear the clothes more comfortably, and the user experience is improved.

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 connected with the housing 20 and serves 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 bracket 32 and the second bracket 34 are rotatably provided at the edge of the housing 20. In other words, the first bracket 32 and the second bracket 34 are rotatably coupled with the housing 20. When the user does not need to use the wearable device 100, the first stand 32 and the second stand 34 may be stacked adjacent to the housing 20 for storage. 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. 4 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 pressure sensor. The triggering device 1001 may be disposed on the first bracket 32 and/or the second bracket 34. In the example of fig. 1, the triggering device 1001 is provided at the first carriage 32. In this manner, detection of the wearing state of the wearing apparatus 100 can be achieved simply and conveniently. It can be understood that the first support 32 is in close contact with the head of the human body, and when the user wears the wearable device 100, the triggering device 1001 disposed on the first support 32 is in contact with the head, so that the corresponding pressure can be sensed.

In addition, the first stent 32 may include a stent body and a wrapping member, the wrapping member wrapping the stent body. The wrap may be resilient, thereby making the user more comfortable to wear. The trigger 1001 may also be wrapped by a wrap and sense the pressure at which the wrap is squeezed.

Of course, the trigger 1001 may be provided on the nose piece 264, as shown in FIG. 5. The nose bridge 264 can accommodate different nose bridge heights, making the user more comfortable to wear. Since the nose piece 264 directly contacts the skin of the user to support the wearable device 100, the trigger 1001 provided at the nose piece 264 senses the corresponding pressure when the user wears the wearable device 100.

The triggering device 1001 may be disposed at the contact portion 266, and as shown in fig. 6, the case 20 includes a contact portion, and the light guide member 70 guides light generated from the display 40 and emits the light from the light guide member 70 toward a side of the contact portion 266. The contact portion 266 may be filled with foam that compresses when squeezed by the forehead of the person to cause the trigger 1001 to sense pressure. The specific position of the triggering device 1001 is not limited herein.

The trigger 1001 may be provided on the elastic band 36 as shown in fig. 7. The elastic band 36 may be tightened by an adjustment mechanism to secure with the user. Tightening of the elastic band 36 squeezes the head so that the trigger 1001 senses the pressure.

In the illustrated example, 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 addition, the triggering device 100 may also be a distance sensor or other device capable of detecting the wearing state of the wearable apparatus 100. The specific form of the triggering device 100 is not limited herein.

A Pressure Transducer is a device or apparatus that senses a Pressure signal and converts the Pressure signal into a usable output electrical signal according to a certain rule. A pressure sensor is usually composed of a pressure sensitive element and a signal processing unit.

Further, pressure sensors include, but are not limited to, piezoelectric pressure sensors, piezoresistive pressure sensors, capacitive pressure sensors, and electromagnetic pressure sensors.

Piezoelectric pressure sensors are mainly based on the Piezoelectric effect (piezo effect), and are electromechanical conversion type and self-generating type sensors. The sensitive element is made of piezoelectric material, when the piezoelectric material is acted by external force, its surface can form electric charge, and after the electric charge is passed through the amplification of charge amplifier and measuring circuit and impedance conversion, it can be converted into electric quantity output in the direct proportion relation with the external force. It is a non-electro-physical quantity that is used to measure force and that can be converted into force.

Piezoresistive pressure sensors are mainly based on the Piezoresistive effect (piezoresitive effect). The piezoresistive effect is used to describe the change in resistance of a material when the material is mechanically stressed. Unlike the piezoelectric effect, the piezoresistive effect only produces a change in impedance and does not produce a charge.

A capacitive pressure sensor is a pressure sensor that uses a capacitance as a sensing element to convert a measured pressure into a change in capacitance. The pressure sensor generally adopts a circular metal film or a metal-plated film as one electrode of a capacitor, when the film is deformed by sensing pressure, the capacitance formed between the film and a fixed electrode is changed, and an electric signal which has a certain relation with voltage can be output through a measuring circuit; the capacitive pressure sensor belongs to a polar distance variation type capacitive sensor and can be divided into a single capacitive pressure sensor and a differential capacitive pressure sensor.

The electromagnetic pressure sensor is a general name of various sensors utilizing an electromagnetic principle, and mainly comprises an inductive pressure sensor, a Hall pressure sensor, an eddy current pressure sensor and the like.

It is understood that, during the process of wearing the wearable device 100, the user will generally adjust the position of the wearable device 100 on the human body to make the position of the wearable device 100 correct. Alternatively, the user may adjust the degree of tightness with which the wearable device 100 is fixed to the human body, so that the user can wear the wearable device comfortably. Correspondingly, the signal curve output by the trigger 1001 may fluctuate.

After the wearable device 100 is fixed, the relative position of the wearable device 100 to the human body and the degree of tightness of fixation are not generally changed. Accordingly, the output signal curve of the trigger device 1001 is relatively stable.

When the user takes off the wearable device 100, the user usually needs to release the fixation between the wearable device 100 and the human body, and the relative position or the fixed tightness between the wearable device 100 and the human body may also be changed. Correspondingly, the signal curve output by the trigger 1001 may fluctuate.

In addition, when the user wears the wearable device 100, the user usually wants the wearable device 100 to operate normally, for example, the display screen is turned on, and the camera and other functional devices of the wearable device 100 operate normally. When the user takes off the wearable device 100, the user usually wants to wait for the wearable device 100, for example, turning off a display screen, a camera of the wearable device 100, or other functional devices.

Therefore, when the fluctuation information satisfies the preset fluctuation condition, the wearing state of the wearable device 100 can be determined according to the signal curve, so that the target operation state of the wearable device 100 can be determined, and the wearable device 100 can be controlled to switch to the target operation state. In other words, step S17 includes: determining the wearing state of the wearing device 100 according to the signal curve; the target operation state of the wearable device 100 is determined according to the wearing state.

In this way, the user can switch the wearable device 100 to the target operation state only by wearing or taking off the wearable device 100 normally without performing other triggering actions. In addition, the electric quantity can be saved, and the utilization rate of the electric quantity is improved. Moreover, false triggering can be prevented, thereby improving the accuracy of control.

In step S12, "acquiring the signal curve output by the trigger 1001 of the wearable device 100" may be to acquire a partial curve after the fluctuation occurs in all the signal curves output by the trigger 1001, and use the partial curve as the signal curve here.

Referring to fig. 8, in an example, when the user presses the power key of the wearable device 100 at time t0 to turn on the wearable device 100, the trigger device 1001 starts outputting the signal value, but the signal value is stable because the user is not wearing the wearable device. The user picks up the wearable device 100 and wears it at time t1, at which time the signal value starts to change. Therefore, a partial curve before the time t1, i.e., the curve L0, can be removed, and a partial curve after the time t1, i.e., the curve L1, can be used as a signal curve.

Referring to fig. 9, in some embodiments, the fluctuation information includes a fluctuation time, the preset fluctuation condition includes a preset time threshold, and the step S14 includes:

step S142: determining the fluctuation times of the signal curve;

the control method comprises the following steps:

step S15: and when the fluctuation times are larger than a preset time threshold value, determining that the fluctuation information meets a preset fluctuation condition.

In some embodiments, the fluctuation information includes a fluctuation number, the preset fluctuation condition includes a preset number threshold, and the processor 101 is configured to determine the fluctuation number of the signal curve; and the fluctuation information is determined to meet the preset fluctuation condition when the fluctuation times are larger than a preset time threshold value.

Therefore, whether the fluctuation information meets the preset fluctuation condition or not is determined through the fluctuation times of the signal curve, and the method is simple, convenient and easy to implement. As described above, when the user puts on or takes off the wearable device 100, the wearable device 100 is adjusted, so that the relative position or the fixed tightness of the wearable device 100 with respect to the human body changes. This is usually an iterative process, which results in multiple fluctuations in the signal profile. After the wearable device 100 is not worn or fixed, the relative position between the wearable device 100 and the human body and the fixed tightness degree are not changed, and the signal curve output by the trigger 1001 is relatively stable. Therefore, when the number of fluctuations is greater than the preset number threshold, it may be determined that the user is wearing or taking off the wearable device 100, so that the target operation state of the wearable device 100 may be determined according to the signal curve.

Referring to fig. 10, in one example, during the time period t0-t1, the wearable device 100 is in a standby state and the display 40 is turned off. The user picks up the wearable device 100 and wears it at time t 1.

In the process of wearing the wearable device 100, the number of fluctuations of the signal curve L1 output by the trigger 1001 is 4, and the last stable signal value of the signal curve L1, that is, the current state value is 5. The preset time threshold is 3 times, and the first preset range is as follows: the signal value is greater than 4.

Since the number of times of fluctuation is greater than the preset number threshold, it can be determined that the fluctuation information satisfies the preset fluctuation condition. Since the current state value is within the first preset range, it may be determined that the target operation state is the first operation state when the user wears the wearable device 100. Then, the processor 101 controls the wearable device 100 to switch to the first operation state. In the first operating state, the display 40 displays normally, and the camera and other functional devices operate normally.

Referring to fig. 11, in the time period t0-t1, the user wears the wearable device 100, the wearable device 100 is in the normal operation state, and the display 40 displays the normal state. The user takes off the wearable device 100 at time t 1.

In the process of taking off the wearing apparatus 100, the number of times of fluctuation of the signal curve L1 output by the trigger 1001 is 4, and the last stable signal value of the signal curve L1, that is, the current state value is 1. The preset time threshold is 3 times, and the second preset range is as follows: the signal value is less than 2.

Since the number of times of fluctuation is greater than the preset number threshold, it can be determined that the fluctuation information satisfies the preset fluctuation condition. Since the current state value is in the second preset range, it can be determined that the user takes off the wearable device 100, and the target operation state is the second operation state. Then, the processor 101 controls the wearable device 100 to switch to the second operation state. In the second operating state, the display 40 is off and the functional device such as the camera is on standby.

In the above example, the preset number threshold is 3. It is understood that in other examples, the predetermined number threshold may be 1, 2, 4, 5, 6, or other values. The specific value of the preset number threshold is not limited herein.

Referring to fig. 12, in some embodiments, step S142 includes:

step S1422: determining a fluctuation line segment of the signal curve, wherein the fluctuation amplitude of the fluctuation line segment is greater than a first preset amplitude threshold value;

step S1424: and determining the fluctuation times according to the number of the fluctuation line segments.

In some embodiments, the processor 101 is configured to determine a fluctuation line segment of the signal curve, wherein a fluctuation amplitude of the fluctuation line segment is greater than a first preset amplitude threshold; and for determining the number of undulations from the number of undulating line segments.

Thus, the fluctuation times of the signal curve can be simply and conveniently determined. In addition, since the fluctuation width of the wavy line segment is greater than the first preset width threshold, a line segment having a fluctuation width less than or equal to the first preset width threshold is not regarded as a wavy line segment. Thus, it is possible to avoid taking into account fine fluctuations not caused by the wearing action of the user, thereby improving the accuracy of control.

In step S1422, a line segment between two adjacent troughs in the signal curve may be used as a wavy line segment; a line segment between two adjacent wave crests in the signal curve can also be used as a fluctuation line segment; the line segment between adjacent troughs and peaks in the signal curve may be taken as the undulation line segment. The specific manner of determining the undulation segment of the signal profile is not limited here.

In step S1424, the number of wavy line segments may be used as the number of times of waving; the number of undulations can also be calculated based on the number of undulating line segments.

Referring to fig. 13, in an example, the fluctuation amplitude of the signal curve L1 is smaller than the first predetermined amplitude threshold value in the time period t2-t3, and the fluctuation of the signal curve L1 in the time period t2-t3 is not counted. After excluding the fluctuation of the signal curve L1 in the period t2-t3, in the signal curve L1, the number of valleys is 4, and the number of line segments between two adjacent valleys is 3, the number of fluctuations of the signal curve L1 can be determined to be 3 times.

In another example, after excluding the fluctuation of the signal curve L1 in the period t2-t3, the number of peaks in the signal curve L1 is 4, and the number of line segments between two adjacent peaks is 3, the number of fluctuations of the signal curve L1 can be determined to be 3.

In yet another example, after excluding the fluctuation of the signal curve L1 in the period t2-t3, the number of line segments between adjacent peaks and valleys in the signal curve L1 is 7, and the number of fluctuations of the signal curve L1 can be determined to be 3.

Referring to fig. 14, in some embodiments, the fluctuation information includes a fluctuation process, the preset fluctuation condition includes a preset process, and the step S14 includes:

step S144: determining the fluctuation process of the signal curve;

the control method comprises the following steps:

step S16: and when the fluctuation process is matched with the preset process, determining that the fluctuation information meets the preset fluctuation condition.

In some embodiments, the fluctuation information includes a fluctuation process, the preset fluctuation condition includes a preset process, and the processor 101 is configured to determine the fluctuation process of the signal curve; and the fluctuation information is determined to meet the preset fluctuation condition when the fluctuation process is matched with the preset process.

Therefore, whether the fluctuation information meets the preset fluctuation condition or not is determined through the fluctuation process of the signal curve, and the method is simple, convenient and easy to implement. It can be understood that since the user needs to adjust the wearable device 100 to fix the wearable device 100 on the head, the user generally loosens the wearable device 100 just when the user puts the wearable device 100 on the head, so that the user can adjust the position of the wearable device 100. Then, the user typically fastens the wearable device 100 to fix the wearable device 100. However, the degree of tightness of the wearable device 100 is not adjusted at one time, and the user may feel uncomfortable because the user is too tight and wearing the device 100. At this time, the wearable device 100 is adjusted from the relaxed state, through the comfortable state, to the tightened state. Then, the user may adjust the wearable device 100 from the tightened state to the comfortable state.

In summary, the user usually experiences four procedures of loose, comfortable, tight, and comfortable when wearing the wearable device 100. These four processes correspond to the fluctuation processes of the signal profile. Thus, when the fluctuation process is matched with the preset process, the fluctuation information is determined to meet the preset fluctuation condition.

In one example, the preset process is: loose, comfortable, tight and comfortable. The user wears the wearable device 100 and adjusts the degree of tightness of the wearable device 100. The fluctuation process determined from the signal profile of the triggering device 100 is: loose, comfortable, tight and comfortable. And if the fluctuation process is matched with the preset process, the fluctuation information can be determined to meet the preset fluctuation condition. Therefore, the target running state of the wearable equipment is determined according to the signal curve, and the wearable equipment is controlled to be switched to the target running state.

In another example, the preset process is: loose, comfortable, tight and comfortable. When the user wearing the wearable device 100 hits the wall, the fluctuation process determined according to the signal curve of the trigger device 100 is as follows: the device is compact and comfortable. And if the fluctuation process is not matched with the preset process, determining that the fluctuation information does not meet the preset fluctuation condition. It is understood that the user does not put on or take off the wearable device 100 at this time, and the fluctuation is caused by the compression by hitting the wall. In this way, it can be ensured that the switching of the target operation state is based on the change of the wearing state of the wearing apparatus 100, thereby avoiding false triggering.

Referring to fig. 15, in some embodiments, step S144 includes:

step S1442: determining a plurality of fluctuation states of the signal curve;

step S1444: the surge process is determined from a plurality of surge states.

In some embodiments, the processor 101 is configured to determine a plurality of fluctuation states of the signal profile; and for determining a waving process from the plurality of waving states.

Therefore, the fluctuation process of the signal curve is determined through a plurality of fluctuation states of the signal curve, and the method is simple, convenient and easy to implement. It is understood that the sequential arrangement of the surge states is the surge process. In other words, in step S1444, a plurality of fluctuation states may be arranged in time series, thereby determining the fluctuation process.

In the present embodiment, the surge state includes: relaxed state, comfortable state, congested state. Of course, in other embodiments, the fluctuation state may also include other states, and the specific form of the fluctuation state is not limited herein.

In step S1442, a plurality of fluctuation states of the signal curve may be determined according to a preset corresponding relationship between the fluctuation range and the fluctuation state. In this way, the determination of the surge state can be simply achieved.

Referring to fig. 16, in one example, the predetermined procedure is: loose, comfortable, tight and comfortable. The fluctuation range 0-4 corresponds to the relaxed state, the fluctuation range 4-5 corresponds to the comfortable state, and the fluctuation range 5-8 corresponds to the congested state. When the user presses the power key of the wearable device 100 at time t0 to turn on the wearable device 100, the trigger device 1001 starts outputting the signal value, but the signal value is stable because the user is not wearing the wearable device. The user picks up the wearable device 100 and wears it at time t1, at which time the signal value starts to change.

The portion of the signal curve L1 at t1-t2 corresponds to the relaxed state, the portion of the signal curve L1 at t2-t3 corresponds to the comfortable state, the portion of the signal curve L1 at t3-t4 corresponds to the tightened state, and the portion of the signal curve L1 after t4 corresponds to the comfortable state. Thus, it can be determined that the fluctuation process in this example is: loose, comfortable, tight and comfortable.

And if the fluctuation process is matched with the preset process, the fluctuation information can be determined to meet the preset fluctuation condition. Therefore, the wearing equipment can be determined to be worn according to the signal curve, and the target operation state is the first operation state. Then, the processor 101 controls the wearable device 100 to switch to the first operation state. In the first operating state, the display 40 displays normally, and the camera and other functional devices operate normally.

Referring to fig. 17, in some embodiments, the target operating state includes a first operating state and a second operating state, and step S17 includes:

step S172: determining a current state value according to the signal curve;

step S174: when the current state value is in a first preset range, determining that the target running state is a first running state;

step S176: and when the current state value is in a second preset range, determining that the target running state is a second running state.

In some embodiments, the target operating state includes a first operating state and a second operating state, and the processor 101 is configured to determine a current state value according to the signal curve; the target running state is determined to be a first running state when the current state value is in a first preset range; and the target operation state is determined to be the second operation state when the current state value is in the second preset range.

In this way, the target operation state of the wearable device 100 is determined according to the signal curve. In the embodiment of the present application, the first operation state is a normal operation state. The second operating state is a standby state. Further, in the first operation state, the display 40 displays normally, and other devices such as a camera work normally, so as to ensure that the user uses the wearable device 100 normally. In the second operating state, the display 40 is turned off, and other functional devices such as the camera are turned off to save power.

In step S172, the current state value is a numerical value for characterizing the current wearing state of the wearable device 100. Specifically, the current state value may be a signal value after a signal curve is stabilized, or may be a pressure value corresponding to the signal value after the signal curve is stabilized. The specific form of the current state value is not limited herein.

In this embodiment, the current state value is a pressure value corresponding to a signal value after the signal curve is stable. The first preset range is: the current state value is greater than the first pressure threshold. The second preset range is: the current state value is less than a second pressure threshold, which is less than the first pressure threshold.

In the example shown in fig. 10, the first pressure threshold is 8N, the signal value after the signal curve is stable is 5, the corresponding pressure value is 10N, which is greater than the first pressure threshold, and the current state value is in the first preset range. Therefore, the target operation state can be determined as the first operation state, i.e., the normal operation state. The processor 101 controls the display 40 to display normally.

The Processor 101 may be an Application Processor (AP). The first pressure threshold value, the second pressure threshold value may be stored in a register of the processor 101. Referring to fig. 18, the triggering device 1001 may send data such as a signal curve to the processor 101, and after determining a control command for the display 40, the processor 101 may send the control command to the display 40, so that the display 40 lights up or turns off the screen according to the control command.

The non-transitory computer-readable storage medium containing computer-executable instructions of the embodiments of the present application, when executed by one or more processors 101, causes the processors 101 to perform the above control method.

For example, performing: step S12: acquiring a signal curve output by a trigger 1001 of the wearable device 100; step S14: determining fluctuation information of the signal curve; step S17: when the fluctuation information meets a preset fluctuation condition, determining a target operation state of the wearable device 100 according to the signal curve; step S18: and controlling the wearable device 100 to switch to the target running state.

The storage medium of the embodiment of the application determines the target running state of the wearable device 100 according to the signal curve output by the trigger device 1001, so that the wearable device 100 is controlled to be switched to the target running state, other trigger actions except wearing by a user are not needed, simplicity and convenience are realized, flexibility is realized, and the user experience can be improved and the electric quantity can be saved. In addition, when the fluctuation information meets the preset fluctuation condition, the target running state is determined according to the signal curve, so that false triggering can be prevented, and the accuracy of control is improved.
