In a first aspect, the present application provides a method of emitting light and flashing, the method being applied to a wearable device, comprising: under the condition of starting a night driving safety mode, acquiring the ambient light brightness; determining a first luminance based on the ambient light level; acquiring a first frequency based on step frequency information or audio information, wherein the step frequency information is information of walking frequency of a user, and the audio information is music information played by the wearable equipment; the light emitting device is controlled to flash based on the first brightness and the first frequency.

In the embodiment of the application, the electronic equipment can combine the ambient light and the user, and flash the brightness when the user walks at night, so as to remind the vehicles and pedestrians around the user to notice the user and ensure the safety of the user traveling at night.

In one possible implementation, the method further includes: acquiring first information, wherein the first information comprises one or more of time information, position information, movement distance information and environment light brightness; and displaying first prompt information based on the first information, wherein the first prompt information is used for prompting a user to start the night driving safety mode. In this way, the wearable device can determine whether to remind the user to start the night security mode based on the position, time, motion state of the user, ambient light and other factors, and the starting instantaneity and necessity. At the same time, starting up without necessity can be avoided, and thus waste of processing resources and energy consumption can be reduced.

In one possible implementation manner, the displaying the first prompt information based on the first information specifically includes: displaying the first prompt information if the time information and the position information meet the current night time under the condition that the first information comprises the time information and the position information; displaying the first prompt information when the first information comprises the movement distance information, wherein the movement distance information is the distance information of continuous movement of a user if the movement distance information is greater than or equal to a distance threshold value; and displaying the first prompt information if the ambient light brightness is smaller than or equal to a first brightness threshold value or a first brightness level under the condition that the first information comprises the ambient light brightness. Therefore, the user can determine whether to start the conditions through one or more conditions, and prompt the user to start the night security mode, so that the rationality and the accuracy of starting time can be ensured, whether to start is determined by the user, and better use experience of the user can be ensured.

In one possible implementation, the method further includes: and starting the night running safety mode under the condition that the operation for starting the night running safety mode is acquired.

In one possible implementation manner, the determining the first brightness based on the ambient light brightness specifically includes: based on the mapping relation between the brightness range and the brightness level, determining the environment brightness level corresponding to the environment brightness, wherein the wearable equipment stores the mapping relation between the brightness range and the brightness level; the first brightness is determined based on the ambient brightness level. Therefore, the environment light brightness and the first brightness are always reversely changed, so that the contrast between the environment light brightness and the brightness displayed by the wearable equipment is as large as possible, the human eyes can more easily notice the light emitted by the wearable equipment, and good warning effect can be provided for surrounding pedestrians or vehicles.

In one possible implementation manner, the step frequency information or audio information based on the step frequency information is used for acquiring the first frequency, which specifically includes: acquiring step frequency information of a user, and determining the frequency of the step frequency information as a first frequency; or, acquiring the played audio information, determining the frequency spectrum information of the audio information, and determining the first frequency based on the frequency spectrum information. Therefore, the luminous frequency of the wearable equipment can not influence the walking or the walking of the user, and the traveling experience of the user can be more comfortable.

In one possible implementation, the method further includes: acquiring time length information, wherein the time length information comprises static time length information and/or bright time length information, the static time length information is time length information for stopping movement of the wearable equipment, and the bright time length information is time length information for enabling the ambient light brightness to exceed the first brightness threshold or the first brightness level; displaying second prompt information when the static time length information is greater than or equal to a first time threshold or the bright time length information is greater than or equal to a second time threshold, wherein the second prompt information is used for prompting a user to exit the night driving safety mode; and in the case that the operation for exiting the night security mode is acquired, exiting the night security mode. Like this, wearable equipment can be in the circumstances that needs to exit night going safe mode, reminds the user to in time exit, on the one hand can reduce the waste of processing resource and energy consumption, on the other hand, can guarantee the start and the exit of night going safe mode, can make things convenient for user's operation, in time reminds the user, gives the more convenient operation of user and more comfortable experience.

In a possible implementation manner, in a case that the first frequency is acquired based on the step frequency information, the flicker is performed based on the first brightness and the first frequency, which specifically includes: acquiring the swing position of the wearable equipment; and under the condition that the swing position of the wearable device is in a first position range of the swing track, the brightness sent by the wearable device is the highest brightness of the flicker brightness, and the first position range is a range that the included angle between the normal line of the light-emitting surface of the wearable device and the horizontal line is smaller than or equal to a first preset included angle. In this way, the flickering of the brightness on the wearable device can propagate furthest when the light emitting surface is oriented horizontally to the ground, which enables vehicles and pedestrians on the road to quickly notice the user. When the light emitting surface faces the ground or sky (dial faces or faces downward), it is often difficult to draw attention from surrounding people, resulting in ineffective light emission or difficulty in drawing attention from others. Therefore, in the present embodiment, the brightest light is emitted at the swing position where the surrounding can be noted, so that the effectiveness of blinking can be ensured, and the safety of the user for night travel can be further improved.

In one possible implementation manner, if the wearable device is worn on a wrist of a user, and the brightness emitted by the wearable device is the highest brightness of the flicker brightness when the swing position of the wearable device is in the first position range of the swing track, specifically including: acquiring the direction of the wearable equipment along a road; acquiring the running direction of the vehicle on the road; if the direction of the wearable device is the same as the running direction of the adjacent vehicle, and if the user swings backwards to the highest position of the wearable device in the first position range, the brightness emitted by the wearable device is the highest brightness of flicker brightness; and under the condition that the direction of the wearable equipment is opposite to the running direction of the adjacent vehicle, if the user swings forwards to the highest position of the wearable equipment in the first position range, the brightness emitted by the wearable equipment is the highest brightness of the flicker brightness. Thus, during the user's walking, the direction of travel of the user and the direction of travel of the surrounding vehicle are either the same or opposite. The flashing of the wearable device often reminds the vehicle of the user who walks, so that if only one side of the user is around, the user reminds the vehicle in front when the person walks opposite to the vehicle; and when the vehicle runs in the same direction, reminding the following vehicle. If the vehicles are arranged on two sides (if vehicles exist in the same direction and opposite directions) around the user, the user can remind the front and rear vehicles, so that the user can effectively remind the vehicles with the period, and the night running safety of the user can be further ensured.

Thus, under the condition that the road and the wearable device are on the same side of the user, the human eyes on the surrounding road can notice the flickering of the wearable device, so that the user is not reminded of replacing the wrist by the third prompting information to wear the wearable device (the intelligent watch). Otherwise, the surrounding eyes cannot notice the flicker, the vigilance effect is poor, and the third prompt information needs to be displayed, so that the night trip safety of the user can be improved.

In this way, the speed of surrounding vehicles may be obtained, and different grade safety modes may be determined based on different vehicle speeds. Under the condition of different levels of safety modes, the wearable device can provide different colors of flicker for the user, so that the user and surrounding vehicles can be distinguished and distinguished, and the safety of the user is ensured.

Therefore, the environment light brightness and the first brightness are always reversely changed, so that the contrast between the environment light brightness and the brightness displayed by the wearable equipment is as large as possible, the human eyes can more easily notice the light emitted by the wearable equipment, and good warning effect can be provided for surrounding pedestrians or vehicles.

In one possible implementation manner, the step frequency information or the audio information is used for acquiring the first frequency, which specifically performs: acquiring step frequency information of a user, and determining the frequency of the step frequency information as a first frequency; or, acquiring the played audio information, determining the frequency spectrum information of the audio information, and determining the first frequency based on the frequency spectrum information. Therefore, the luminous frequency of the wearable equipment can not influence the walking or the walking of the user, and the traveling experience of the user can be more comfortable.

Like this, wearable equipment can be in the circumstances that needs to exit night going safe mode, reminds the user to in time exit, on the one hand can reduce the waste of processing resource and energy consumption, on the other hand, can guarantee the start and the exit of night going safe mode, can make things convenient for user's operation, in time reminds the user, gives the more convenient operation of user and more comfortable experience.

In a possible implementation manner, in a case that the first frequency is acquired based on the step frequency information, the flicker is performed based on the first brightness and the first frequency, specifically performing: acquiring the swing position of the wearable equipment; and under the condition that the swing position of the wearable device is in a first position range of the swing track, the brightness sent by the wearable device is the highest brightness of the flicker brightness, and the first position range is a range that the included angle between the normal line of the light-emitting surface of the wearable device and the horizontal line is smaller than or equal to a first preset included angle. In this way, the flickering of the brightness on the wearable device can propagate furthest when the light emitting surface is oriented horizontally to the ground, which enables vehicles and pedestrians on the road to quickly notice the user. When the light emitting surface faces the ground or sky (dial faces or faces downward), it is often difficult to draw attention from surrounding people, resulting in ineffective light emission or difficulty in drawing attention from others. Therefore, in the present embodiment, the brightest light is emitted at the swing position where the surrounding can be noted, so that the effectiveness of blinking can be ensured, and the safety of the user for night travel can be further improved.

In one possible implementation manner, if the wearable device is worn at the wrist of the user, and the brightness emitted by the wearable device is the highest brightness of the flicker brightness when the swing position of the wearable device is in the first position range of the swing track, specifically performing: acquiring the direction of the wearable equipment along a road; acquiring the running direction of the vehicle on the road; if the direction of the wearable device is the same as the running direction of the adjacent vehicle, and if the user swings backwards to the highest position of the wearable device in the first position range, the brightness emitted by the wearable device is the highest brightness of flicker brightness; and under the condition that the direction of the wearable equipment is opposite to the running direction of the adjacent vehicle, if the user swings forwards to the highest position of the wearable equipment in the first position range, the brightness emitted by the wearable equipment is the highest brightness of the flicker brightness. Thus, during the user's walking, the direction of travel of the user and the direction of travel of the surrounding vehicle are either the same or opposite. The flashing of the wearable device often reminds the vehicle of the user who walks, so that if only one side of the user is around, the user reminds the vehicle in front when the person walks opposite to the vehicle; and when the vehicle runs in the same direction, reminding the following vehicle. If the vehicles are arranged on two sides (if vehicles exist in the same direction and opposite directions) around the user, the user can remind the front and rear vehicles, so that the user can effectively remind the vehicles with the period, and the night running safety of the user can be further ensured.

In one possible implementation, the wearable device further performs: acquiring a wearing direction of the wearable device, wherein the wearing direction comprises a left side or a right side of a user wearing in a forward direction; acquiring a position direction of the wearable device in a road, wherein the position direction comprises the left side or the right side of the road of the wearable device in the advancing direction; and displaying third prompt information when the wearable device is worn on the left side of the user and the wearable device is on the left side of the road in the advancing direction or when the wearable device is worn on the right side of the user and the wearable device is on the right side of the road in the advancing direction, wherein the third prompt information is used for reminding the user to adjust the current wearing direction of the wearable device.

Detailed Description

The technical solutions of the embodiments of the present application will be clearly and thoroughly described below with reference to the accompanying drawings. Wherein, in the description of the embodiments of the present application, unless otherwise indicated, "/" means or, for example, a/B may represent a or B; the text "and/or" is merely an association relation describing the associated object, and indicates that three relations may exist, for example, a and/or B may indicate: the three cases where a exists alone, a and B exist together, and B exists alone, and furthermore, in the description of the embodiments of the present application, "plural" means two or more than two.

The terms "first," "second," and the like, are used below for descriptive purposes only and are not to be construed as implying or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature, and in the description of embodiments of the application, unless otherwise indicated, the meaning of "a plurality" is two or more.

The wearable device provided by the embodiment of the application can be a smart watch, a smart bracelet and the like.

Fig. 1 is a schematic diagram of a wearable device according to an embodiment of the present application. As shown in fig. 1, taking a wearable device as an example of a smart watch, the side surface of the smart watch 110 is provided with crowns 111 and 112, and the crowns 111 and 112 are connected with the smart watch 110 through a connecting component. The front of the intelligent watch 110 is provided with a dial 113, and a display screen 114 is arranged on the dial 113 body, so that a user can conveniently touch and view the display content on the display screen 114, and the display screen 114 on the dial body is often larger. The dial 113 is connected at its upper and lower ends to the wristband 115. The display 114 of the dial may display information such as time, date, weather, heart rate, etc., and the user may adjust the information according to the need, which is not limited in the present application.

A breathing lamp, a light-emitting diode (LED), a display screen, or a light-emitting device having a specific illumination intensity function may be mounted on a dial, a crown, or a dial outer ring of the smart watch. The position in which this light emitting device is mounted is not limited.

When a user runs at night, the safety of traveling at night is poor because the light is darker and more vehicles and people come and go. In order to avoid accidents caused by darker road light and the like as far as possible, the intelligent watch worn by the user at night can turn on the light. However, for a smart watch, a fixed light intensity may not necessarily be able to alert the human eye in all light environments. For example, when the night curtain just falls, the sight of the eyes is not good, but the hand ring can not obviously contrast with the current environment to remind people on the road when the light with certain illumination intensity is emitted. This results in the same poor safety of night travel.

In the embodiment of the application, when the user obtains the current time, place, light and other information, the wearable device can determine a first brightness with larger brightness contrast with the current environment under the condition that the user determines that the current environment brightness is worse, and the first frequency is determined through walking frequency of the user or music played by the wearable device. The wearable device may then control the light emitting means to flash at the first brightness and the first frequency. Therefore, the wearable device can remind vehicles and pedestrians on the roadside through the flashing light rays to pay attention to the position of the current user, so that the safety of night travel of the user can be improved. In addition, the flicker frequency of the light of the electronic equipment is suitable for walking of a user or music heard by the user, and the flicker of the light is more comfortable for the user, so that the night travel experience of the user can be improved.

Referring to fig. 2, fig. 2 is a flow chart of a method for flashing light according to an embodiment of the application. As shown in fig. 2, the method of emitting light and flashing includes, but is not limited to, the following steps.

S201, the wearable device displays first prompt information under the condition that the first information meets the preset condition.

The first prompt message is used for enabling the electronic equipment to start a night-walk safety mode. The first information includes one or more of current time information, position information, movement distance information, and ambient light level. The time information may be information such as the current date and time minute and second. The location information may be information indicating a current spatial location. For example, the latitude and longitude information may be other representation modes, and is not limited. The movement distance information may be a distance that the user is currently continuously moving. For example, the user currently runs 500m (exercise distance information is 500 m). The ambient light level is the brightness information of the environment in which the wearable device is currently located.

The first information meeting the preset condition may include meeting one or more of the following conditions:

condition 1: in the case where the time information and the position information satisfy the local night time, the condition 1 is satisfied.

The location information may be longitude and latitude. The time information may be time of year, month, day, minute, and second. The wearable device may obtain location information of the electronic device by obtaining global positioning system (global positioning system, GPS) data, (wireless fidelity, wi-Fi) location data, location data of a cell (cell) base station, and so on.

By way of example, it may be that the time information is Beijing time 2021, 12, 21:36:25, and the position information is 29 degrees North latitude and 116 degrees east longitude. The electronic device may be at a local night time at this time and therefore may determine that condition 1 is met.

Through the judging process of the condition 1, the wearable device can judge whether the current local time is at night, so that a user can be reminded of starting a night travel safety mode, and the travel safety of the user is ensured.

Condition 2: in the case where the movement distance information is greater than or equal to (greater than) the distance threshold value, condition 2 is satisfied.

Wherein the wearable device can acquire the walking and/or running distance of the current user of the user through the acceleration sensor (acceleration transducer, ACC). The movement distance information can be the distance of running of the user, the distance of walking and running of the user, the distance of walking of the user and the distance of running of the user, and is not limited. In addition, the distance threshold in the embodiment of the application can be 100m,200m, 300m, 500m and other lengths, without limitation.

For example, the wearable device may acquire that the distance (exercise distance information) of the current user running is 205m and the distance threshold is 200m,205m >200m through the ACC, and thus, it may be determined that the exercise distance information is greater than the distance threshold, satisfying the condition 2.

Whether the user goes out or not can be judged through the distance information, and if the distance threshold is too short, the user can be reminded of starting a night going safety mode if the user does not go out; if the user has traveled for a long time, at this time, it is determined whether the user starts the night security mode, and the effective time for reminding the user has elapsed for a period of time, and the user security cannot be improved within a sufficient time, which is also wasteful of the present function. Only after detecting that the trip has been a period of time, wearable equipment reminds the user to open night going safety mode, can hold the best opportunity of opening, guarantees the validity and the sufficiency of safety mode use.

Condition 3: condition 3 is satisfied where the ambient light level is less than or equal to (less than) the first brightness threshold or the first brightness level.

In one possible scenario, the wearable device may obtain the ambient light level through a light intensity sensor. The wearable device may then compare the magnitude between the ambient light level and the first brightness threshold. When the ambient light level is less than or equal to (less than) the first luminance threshold, condition 3 is satisfied; otherwise, not satisfied. Wherein the first luminance threshold may be 200 lumen, 300lumen, 400lumen, 500lumen, etc., and embodiments of the present application are not limited.

Illustratively, the wearable device may obtain that the current ambient light level is 200lumen, the first luminance threshold is 500 lumens, 200<500, and thus, condition 3 is satisfied.

In another possible scenario, the wearable device may obtain the ambient light level through a light intensity sensor. The wearable device may then determine an ambient brightness level based on the ambient light level, where the ambient brightness level is less than or equal to (less than) the first brightness level, may determine that condition 3 is satisfied; otherwise, not satisfied. The wearable device may store a mapping relationship between the brightness range and the brightness level (specifically, refer to the description of table 1, which is not repeated), and after the wearable device obtains the ambient light brightness, the wearable device may determine the ambient brightness level based on the mapping relationship. The first brightness level may be 3, 4, 5 levels in table 1, and the like, without limitation.

For example, the wearable device may obtain the current ambient light level to be 400 lumens, the ambient light level may be 3 through the mapping relationship in table 1, and in the case that the first brightness level is 5, the wearable device may determine that the condition 3 is satisfied.

In the above condition 3, the wearable device may collect the ambient light level, determine whether the environment where the user is located is suitable for starting the night security mode. If the user walks in an environment with sufficient brightness, there is no need to turn on the night security mode, which is wasteful of processing resources and power consumption, and therefore, the condition 3 judgment can ensure the necessity and effectiveness of the startup of the night security mode.

It should be noted that, the first information may satisfy the preset condition, and may be one or more of the 3 conditions, and a kind and an order of executing the 3 conditions are not limited.

Fig. 3 is a schematic flow chart of a night-time security mode starting method according to an embodiment of the present application. As shown in fig. 3, the process of determining that the wearable device displays night-time security mode information may include the steps of:

and S301, the wearable device acquires time information and position information.

The wearable device may periodically acquire time information and location information, for example, once in 5 minutes, or once in 30 minutes, and the acquired time interval is not limited. The specific description of the wearable device acquiring the time information and the position information can refer to the related description of the step 1, and the description is omitted.

S302, the wearable device judges whether the time information and the position information meet the local night time. If yes, S303 is executed, otherwise, the current flow is ended.

Specific reference may be made to the description related to the above condition 1, and no description is repeated.

And S303, the wearable device acquires the movement distance information.

Specific reference may be made to the description related to the above condition 2, and no description is repeated.

And S304, the wearable device judges whether the movement distance information is greater than or equal to (greater than) a distance threshold value. In the case where the distance information is greater than or equal to (greater than) the distance threshold value, step S305 is performed; otherwise, the current flow is ended.

S305, the wearable device acquires the ambient light brightness.

Specific reference may be made to the description related to the above condition 3, and no description is repeated.

S306, the wearable device judges whether the ambient light brightness is smaller than or equal to (smaller than) a first brightness threshold value or a first brightness level. In the case where the ambient light level is less than or equal to (less than) the first luminance threshold value or the first luminance level, step S307 is performed; otherwise, the current flow is ended.

S307, the wearable device displays the first prompt information.

A specific description of S307 may refer to the following description of fig. 4 and related displays, which are not repeated here.

Under the condition that the wearable device determines that the first information meets the preset condition, first prompt information can be displayed, wherein the first prompt information is used for prompting a user to start the night-walk safety mode. The night security mode starting information is information for reminding a user to start the night security mode. The display mode can be one or more of text information, vibration information, brightness information, sound information, picture information and the like, and is not limited.

Fig. 4 is a schematic diagram illustrating a user interface of a wearable device according to an embodiment of the present application. As shown in fig. 4, the display screen of the wearable device 410 may display a first screen 411, and the first screen 411 may display information prompting the user to turn on the security mode, i.e., information of "whether to turn on the night security mode". According to the prompt information, the user can click the 'confirm' control to start the night security mode or click the 'cancel' control to select not to start the night security mode. In the event that the wearable device acquires an operation to the "determine" control, the wearable device 410 may initiate a night safe mode.

In the event that the wearable device acquires a control to initiate a secure mode, the wearable device may acquire a night walk secure mode initiation event.

S202, under the condition that a night security mode starting event is acquired, the wearable device acquires the ambient light brightness.

The wearable device can acquire the current ambient light brightness under the condition that the current night security mode starting event is acquired, namely, the night security mode is determined to be started. The wearable device can acquire the current ambient light level through the light intensity sensor.

In one possible implementation, the wearable device obtains a night safe mode initiation event in response to an operation on the "determine" control. In the event that a night-time security mode initiation event is acquired, the wearable device may begin to acquire the current ambient light level. The wearable device can acquire the current ambient light level through the light intensity sensor. The ambient light level here may be the same as or different from that in S201, without limitation.

S203, the wearable device determines the first brightness based on the ambient light brightness.

Wherein the first brightness is a brightness of the wearable device for display. In the event that the wearable device acquires ambient light level, the first brightness may be determined based on the ambient light level.

First, the wearable device may determine an ambient brightness level α based on the ambient light level.

In a possible case, the electronic device may store a mapping relationship between the brightness range and the brightness level, based on the mapping relationship, the wearable device may determine the brightness range based on the ambient light brightness, and determine the brightness level corresponding to the ambient light brightness based on the mapping relationship.

Wherein, the mapping relation stored between the brightness range and the brightness level can be stored in the form of a mapping table.

TABLE 1

Table 1 is a mapping table between luminance ranges and luminance levels as disclosed in the embodiments of the present application. As shown in table 1, in the case where the ambient light x range is less than or equal to 0.002 lumens, the brightness level α is 0; in the case where the ambient light luminance α is in the range of greater than 0.002 lumens and less than or equal to 1 lumen, the luminance level α is 1; in the case where the ambient light brightness range is greater than 1 lumen and less than or equal to 200 lumens, the brightness level α is 2; in the case where the ambient light brightness range is greater than 200 lumens and less than or equal to 400 lumens, the brightness level α is 3; in the case where the ambient light brightness range is greater than 400 lumens and less than or equal to 600 lumens, the brightness level α is 4; in the case where the ambient light brightness range is greater than 600 lumens and less than or equal to 800 lumens, the brightness level α is 5; in the case where the ambient light brightness range is greater than 800 lumens and less than or equal to 1000 lumens, the brightness level α is 6; in the case where the ambient light brightness range is greater than 1000 lumens and less than or equal to 1300 lumens, the brightness level α is 7; in the case where the ambient light brightness range is greater than 1300 lumens and less than or equal to 2000 lumens, the brightness level α is 8; in the case where the ambient light brightness range is greater than 2000 lumens and less than or equal to 5000 lumens, the brightness level α is 9; in the case where the ambient light brightness range is greater than 5000 lumens, the brightness level α is 10.

It should be noted that the above-described mapping table between the luminance range and the luminance level is merely an exemplary illustration, and is not limiting.

Illustratively, in the case where the current ambient light intensity is 456lm, 400<456<600, and therefore, the wearable device may determine that the ambient light level α is 4.

In the case where the ambient brightness level α and the maximum brightness M of the wearable device are acquired, the electronic device may acquire the first brightness β based on the ambient brightness level α and the maximum brightness M. Wherein, M is the maximum brightness value which can be sent out by the preset wearable equipment, and the brightness range of M is in the range corresponding to the brightness level of 5 to 10.

In a possible case, the first brightness β may be determined as:

β＝M(10-α)/10

illustratively, table 2 is a mapping relationship between an ambient light level and a calculated first luminance disclosed herein.

TABLE 2

Ambient light level (. Alpha.)	Brightness level (beta) of first brightness
		0	M
1	0.9M
		2	0.8M

As shown in table 2, as a increases, the smaller β can result in a darker ambient light level and a brighter brightness emitted by the wearable device. The brightness contrast between the environment light and the light emitted by the wearable equipment is large, so that people can easily notice the environment light, and the travel safety of the user can be ensured.

In another possible case, the first brightness β may be determined as:

β＝M·(10-α ² )/10

wherein M is the maximum brightness M of the wearable device, and α is the brightness level of the ambient light, i.e., the ambient brightness level. The specific formula for determining the first luminance β is not limited. The above-mentioned first luminance β may be obtained in such a manner that β is smaller as α increases; as a decreases, β is larger.

Therefore, the environment light brightness and the first brightness are always reversely changed, so that the contrast between the environment light brightness and the brightness displayed by the wearable equipment is as large as possible, the human eyes can more easily notice the light emitted by the wearable equipment, and good warning effect can be provided for surrounding pedestrians or vehicles.

S204, the wearable device acquires the first frequency based on the step frequency information or the audio information.

The wearable device may first acquire frequency information or audio information, and then may determine the first frequency based on the frequency information or audio. The first frequency is a change frequency of brightness displayed by the wearable device.

Two possible cases are described in detail below:

in one possible implementation, the wearable device obtains the first frequency based on the step frequency information.

The wearable device may first acquire the frequency of the user walking or running through the acceleration sensor ACC, and then may determine this frequency as the first frequency of the electronic device.

In another possible implementation, the wearable device obtains the first frequency based on the audio information.

When the current wearable device plays music, the wearable device can acquire the currently played music through the music module, so that music information can be obtained. The wearable device may then perform a fast fourier transform (fast Fourier transform, FFT) on the music information, determine frequency domain information for the audio so that the most dominant frequency of the music may be analyzed, and determine this frequency as the first frequency.

Specifically, the wearable device performs FFT conversion on the played music to obtain spectrum data. And drawing a frequency spectrum histogram of the audio information according to the frequency spectrum data of the watch. And then the wearable device can determine the frequency with the highest frequency content as the first frequency according to the frequency distribution condition in the frequency spectrum histogram.

The user may adjust or select the mode of the first frequency. In the case that the user selects the step frequency mode, the wearable device may acquire the first frequency based on the step frequency information; in the event that the user selects the audio mode, the wearable device may determine the first frequency based on the audio information. Further, the wearable device determines that the default mode of the first frequency is a step frequency mode.

In the above embodiment, since the frequency of the change of the brightness of the wearable device is the first frequency, the first frequency is either the same as the frequency of walking or running of the user, or is consistent with the frequency of music heard by the user, so that the frequency of the light emission of the wearable device does not influence the walking or walking of the user, and the traveling experience of the user is more comfortable.

S205, the wearable device controls the light emitting device to flash based on the first brightness and the first frequency.

In one possible implementation, the wearable device may blink based on the first brightness and the first frequency.

The wearable device can determine the first brightness as the brightness maximum value in the flickering process, and the first frequency is the flickering frequency and performs brightness change.

Fig. 5 is a schematic diagram of a set of wearable device brightness change curves disclosed in an embodiment of the present application. As shown in (a) to (D) of fig. 5, the abscissa of the luminance change curve is time, and the ordinate is luminance. The brightness of the wearable device changes according to the same period, the time length of the changing period is T, and T is the reciprocal of the first frequency. The maximum value of the luminance is the first luminance L. The curve of the luminance change is not limited, and may be a change in a zigzag shape as shown in fig. 5 (a), a columnar change as shown in fig. 5 (B), or another zigzag change as shown in fig. 5 (C). But may also be a variation of the corrugation of (D) in fig. 5. Note that the luminance changes shown in (a) to (D) in fig. 5 may be envelope diagrams of luminance changes. In addition, the specific shape of the brightness change may be other possible, and the embodiment of the present application is not limited.

For example, the wearable device may flash by means of a breathing light, the maximum brightness of the flash being the first brightness and the frequency of the flash being the first frequency.

When a user walks on a pavement on a road, the action of a swing arm of the user or the back-and-forth swing track of limbs can be traced no matter walking or running. The wearable device may determine which position is currently in the user's arm swing cycle through the acceleration sensor.

Whereas the light emitting brightness of the wearable device is periodically blinking, the frequency of the blinking may be referred to the frequency of the user walking. In the process of walking or running of the user, the step frequency is consistent with the frequency of the arm swing, so that the wearable device can acquire the swing position of the user when the wearable device is worn on the wrist of the user or the like. This swing position is a position at a certain point in the locus of the swing of the wrist cycle while walking or running.

In the case where the swing position is acquired, the wearable device may determine whether the swing position of the wearable device is in the first position range of the swing trajectory based on the swing position. And under the condition that the swing position of the wearable device is in a first position range of the swing track, the brightness emitted by the wearable device is the highest brightness of the flicker brightness.

The first position range is a range in which an included angle between a normal line of the light emitting surface of the wearable device and a horizontal line is smaller than or equal to a first preset included angle. The first preset included angle is the maximum value of the included angle between the normal line of the light-emitting plane of the electronic equipment and the horizontal direction of the ground. The first preset included angle may be 60 degrees, 45 degrees, 30 degrees, or the like, and is not limited.

The wearable device can acquire the moving direction, moving speed, moving distance and the like of the wearable device through the acceleration sensor and/or the gyroscope sensor, the swinging track of the wearable device is often determined, the moving direction, moving speed, moving distance and the like of each position on the swinging track are specific, and therefore the swinging position can be determined. Furthermore, the wearable device may acquire the direction of the normal line of the light emitting surface through the gyro sensor.

If the luminous surface is the dial plate of the intelligent watch, the flash of the brightness on the dial plate can be transmitted furthest if and only if the dial plate is oriented horizontally with the ground, so that the vehicles and pedestrians on the road can quickly notice the user. When the dial faces the ground or sky (dial faces or faces down), it is often difficult to draw attention from surrounding people, resulting in ineffective lighting or difficulty in drawing attention from others. Therefore, in the present embodiment, the brightest light is emitted at the swing position where the surrounding can be noted, so that the effectiveness of blinking can be ensured, and the safety of the user for night travel can be further improved.

As in fig. 5 (a) - (D) brightness always has a maximum value, i.e. the first brightness, just at this brightness the wearable device is in the first position. I.e. when the person's arm just swings to the point where it is most advantageous for the surrounding human eye to be able to see the illuminated object most clearly, the wearable device emits the brightest light. Therefore, the combination of the swinging position and the flicker period can effectively enable the periodic pedestrians to notice the user, so that the safety of the device can be further ensured. In addition, in this case, the user does not need to always keep the brightness at the maximum brightness, and thus the electric power can be saved.

In one possible embodiment, the distance between the vehicle and the pedestrian is often the distance between the motor vehicle lane and the pavement. Pedestrians can walk on two sides of the road, and vehicles run in the middle of the road.

The wearable device can acquire the direction of the wearable device along the road, namely the direction of the user walking. The electronic device may also acquire the direction of travel of the vehicle on the road, i.e. the direction in which the vehicle is travelling on the surrounding road. Thereafter, the wearable device may determine whether the direction in which the wearable device proceeds is the same as the direction in which the adjacent vehicle is traveling. If the direction of the wearable device is the same as the running direction of the adjacent vehicle, and if the user swings backwards to the highest position of the wearable device in the first position range, the brightness emitted by the wearable device is the highest brightness of the flicker brightness; under the condition that the direction of the wearable device is opposite to the running direction of the adjacent vehicle, if the user swings forwards to the highest position of the wearable device in the first position range, the brightness emitted by the wearable device is the highest brightness of the flicker brightness.

During the user's travel, the direction of travel of the user and the direction of travel of the surrounding vehicle are either the same or opposite. The flashing of the wearable device often reminds the vehicle of the user who walks, so that if only one side of the user is around, the user reminds the vehicle in front when the person walks opposite to the vehicle; and when the vehicle runs in the same direction, reminding the following vehicle. If the vehicles are arranged on two sides (if vehicles exist in the same direction and opposite directions) around the user, the user can remind the front and rear vehicles, so that the user can be effectively reminded of the vehicles with the periodic period, and further the night running safety of the user can be ensured.

In the process of wearing the wearable device by a user, as people generally walk at the position of the edge of the road, the brightness flicker of the wearable device can be ensured to remind the attention of surrounding eyes only when the wearable device is worn on the side facing the road. Therefore, the wearable device can be worn on the side facing the road as much as possible, while ensuring the safety of pedestrians.

In a possible embodiment, the wearable device may acquire a wearing direction of itself, the wearing direction including being worn on the left or right side of the user in the advancing direction. The wearable device may also acquire a position direction of itself in the road, the position direction including the wearable device being on the left or right side of the road in the forward direction. And displaying third prompt information when the wearable device is worn on the left side of the user and the wearable device is on the left side of the road in the advancing direction or when the wearable device is worn on the right side of the user and the wearable device is on the right side of the road in the advancing direction, wherein the third prompt information is used for reminding the user to adjust the wearing direction of the wearable device currently. That is, it can be understood that, in the case where the road and the wearable device are on the same side of the user, the human eyes on the surrounding road can notice the flickering of the wearable device, and therefore, the user is not reminded to replace the wrist with the wearable device (smart watch) by the third hint information. Otherwise, the surrounding eyes cannot notice the flicker, the vigilance effect is poor, and the third prompt information needs to be displayed, so that the user can wear the mask by changing the wrist. The third prompting information can be voice prompting, text prompting, vibration prompting and the like, and is not limited. For example, the third prompt may be "please replace the wrist with a watch for your safety".

The more usual the road, the faster the speed of the vehicle, the greater the possibility of traffic accidents and the severity of the accidents, so that the speed of surrounding vehicles can be obtained, and different levels of safety modes can be determined according to different vehicle speeds. Under the condition of different levels of safety modes, the wearable device can provide different colors of flicker for the user, so that the user and surrounding vehicles can be distinguished and distinguished, and the safety of the user is ensured.

In one possible implementation, the wearable device may obtain a first rate of the roadway; opening a primary safety mode if the vehicle speed is greater than or equal to a first speed threshold; opening a secondary safety mode if the vehicle speed is less than the first speed threshold and greater than or equal to a second speed threshold; if the vehicle speed is less than the second speed threshold, starting a three-level safety mode; wherein the first speed may be an average speed of the vehicle or an average speed of the vehicle through the road, the first speed threshold being greater than the second speed threshold. For example, the first rate threshold is 60km/h and the second rate threshold is 30km/h. The first-level safety mode corresponds to flashing first color, the second-level safety mode corresponds to flashing second color, and the third-level safety mode corresponds to flashing third color. For example, in the first level security mode, the flashing first color is bright yellow; in the second-level safety mode, the second flashing color is orange yellow; in the three-level safety mode, the flashing third color is dark yellow.

In the above-described embodiments, it is most easy for pedestrians and drivers of vehicles on the road to notice that the pedestrians on the road should be the varying light, and the human eyes can be most attracted to the situation that the light is greatly different from the light in the current environment. Thereby improving the safety of the user walking at night.

In the above embodiment, when the wearable device is specifically in the night safe mode, the wearable device may exit the night safe mode when the user finishes walking at night or running through the content that the LED blinks.

The wearable device may acquire duration information, which is time information that the user continues in a certain state. It may then be determined whether to display the second hint information based on the duration information. The second prompt message is used for reminding the user to exit the night security mode. The duration information may include still duration information or bright duration information. The stationary duration information may be a length of time that the user stops walking or running; the bright time length information is the time length that the ambient light brightness exceeds the first brightness level or the first brightness threshold.

In a possible implementation manner, the wearable device can acquire the walking or running condition of the user through the acceleration sensor ACC, and in the case that the user stops moving (static duration information) beyond the first time threshold, the wearable device can remind the user to exit the walking safety mode.

For example, when the current user is stationary at a certain position, the length of time that the wearable device acquires that the user is stationary is 2 minutes, and the 2 minutes are greater than the first time threshold value 90s, so that the wearable device can display second prompt information to remind the user to exit from the current night-walk safety mode. The wearable device may refer to the description related to fig. 4, and details are not repeated. After the user sees the prompt message of whether to exit the night security mode displayed on the display screen, the user can click the "confirm" control to exit the night security mode; or clicking the exit control to keep the current night security mode. After the wearable device acquires the operation of determining to exit the night safe mode, the wearable device exits the night safe mode. Upon exiting the night safe mode, the wearable device may stop the first frequency and the first brightness from blinking, i.e., stop performing steps S203-S205.

In another possible implementation manner, the wearable device may determine that the time (the light duration information) of the brightness level is greater than (greater than or equal to) the brightness threshold or greater than the second time threshold through the ambient light brightness, and may display a second prompt message to remind the user to exit from the current safe night-driving mode.

Illustratively, the user enters the room with the smart band, the indoor brightness 1000lm is greater than the current brightness threshold 400lm, and the user enters the room (the light duration information) for more than two minutes (the second time threshold), the smart band may display the second prompt information, and prompt the user to turn off the current night-time security mode. The second prompt information is specifically referred to the description of the previous embodiment, and is not repeated.

It should be noted that the above two time thresholds, i.e., the first time threshold and the second time threshold, are both illustrative and not limiting.

In the two embodiments, the wearable device can remind the user to exit in time under the condition that the night security mode needs to exit, so that waste of processing resources and energy consumption can be reduced on one hand, on the other hand, starting and exiting of the night security mode can be guaranteed, operation of the user can be facilitated, the user is reminded in time, and more convenient operation and more comfortable experience are provided for the user.

Fig. 6 is a software configuration block diagram of an electronic device according to an embodiment of the present application.

The layered architecture of the electronic device divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. In some embodiments, taking an electronic device as an example of a smart watch, as shown in fig. 4, an operating system may be divided into six layers, namely, a UI (User Interface) application layer, an application framework layer, an algorithm layer and a kernel layer from top to bottom.

The UI application layer may include a series of application packages, which may be, for example, a communication application, a system application, a health application, dial management, and the like. The communication applications may include, among other things, information, call records, contacts, calls, and the like. Additionally, system applications may include brightness adjustment, night security modes, and the like.

Wherein, the brightness adjustment can be used for adjusting the brightness emitted by the LED or the liquid crystal display screen (liquid crystal display, LCD) of the current smart watch. In addition, the night security mode can be turned on or off for the user to use under the condition of night travel.

The application framework layer provides an Application Programming Interface (API) and a programming framework for the application of the application layer. The application framework layer includes a number of predefined functions. As shown in fig. 6, the application framework layer may include a system base module, a night security module, a hardware service module, and the like.

The system base module may include, among other things, communication services and audio services, wherein the audio services may be used to play music and the like. Communication services may include messaging services, conversation services, interworking, and contacts.

In addition, the hardware service module may include a location service, an NFC (Near Field Communication ) service, BLE (bluetooth), and the like. The positioning service may acquire one or more relevant positioning information of GPS, wiFi, cell, etc. of the electronic device.

The frame layer may also include a night walk security module. The night security module is used for executing related functions of the night security mode.

In a first aspect, the night security module determines whether to initiate a night security mode. The night-time security module may acquire ambient light (from the light intensity sensor) through sensor drive, acceleration information of the electronic device (from the acceleration sensor ACC). The position information obtained by the positioning service or GPS and the like can also be obtained; time information can also be obtained by a Real-Time Clock (RTC); the movement distance information and the like may also be acquired based on the acceleration information and the position information. In this way, the night security module may acquire the first information, and may determine whether to display information for reminding the user to start the night security mode, which may be specifically described with reference to S201.

In a second aspect, the night security module performs a certain regular flashing in the night security mode. The night driving safety module can display through the display drive under the condition of being started. After the safety mode is started, the night-time safety module can acquire first brightness based on the ambient light brightness and first frequency through an algorithm library, and after the first brightness and the first frequency are acquired, the night-time safety module can flash through a display screen or an LED or the like. Reference may be made specifically to the descriptions of S203, S204, and S205.

In a third aspect, the night security module determines whether to exit the night security mode. After the secure mode is turned on, the night security module may also acquire timing information through counter Timer or pulse width modulation (Pulse width modulation, PWM). The timing information may be a time length for which the user is stationary, a time length for which the ambient light level is greater than a certain threshold value, and the like. Thereafter, it may be determined whether to exit the night security mode based on the timing information, specifically, refer to the description of step S205.

The algorithm layer, which may also be referred to as a Libs layer, may include a series of algorithm models and internal libraries. The algorithm layer may include a base library, an algorithm library, a legacy bluetooth protocol stack, and a BLE protocol stack. The algorithm library may include audio algorithms and motion algorithms, among others.

Wherein the audio algorithm may obtain the first frequency based on the audio information. Specifically, the audio algorithm may acquire the audio information currently played by the audio service, then perform FFT on the audio information to obtain frequency distribution information, and extract the value with the largest frequency in the audio information as the first frequency, which may be specifically described with reference to S204, and will not be described in detail.

The motion algorithm may determine the first frequency based on the step frequency. Specifically, the audio algorithm may acquire the step frequency information of the user by acquiring the acceleration sensor, and determine the step frequency as the first frequency, which may be specifically described with reference to S204, which is not described in detail.

The kernel layer is a layer between the hardware and the software layers described above. The kernel layer may include a hardware abstraction layer (Hardware Abstraction Layer, HAL) and a hardware Driver layer (Driver). The hardware abstraction layer may at least include a sensor driver, a display driver, an audio driver, a bluetooth driver, and the like. The hardware abstraction layer may include a display screen (or LCD), a Timer/RWM, an acceleration sensor ACC, a light intensity sensor, a GPS, an RTC, a processor, and a memory.

The sensor driver is used for receiving data acquired by each sensor and sending the data acquired by each sensor to the algorithm layer or the application framework layer. For example, the sensor driver may receive data collected by the acceleration sensor and the light intensity sensor and send the data to an algorithm library of the algorithm layer.

It is to be understood that the components included in the UI application layer, the application framework layer, the algorithm layer, the kernel layer, and the like shown in fig. 4 do not constitute a specific limitation of the electronic device 100. In other embodiments of the application, electronic device 100 may include more or fewer components than shown, or certain components may be combined, or certain components may be split, or different arrangements of components.

It will be appreciated that the wearable device, in order to achieve the above-described functions, includes corresponding hardware and/or software modules that perform the respective functions. The present application can be implemented in hardware or a combination of hardware and computer software, in conjunction with the example algorithm steps described in connection with the embodiments disclosed herein. Whether a function is implemented as hardware or computer software driven hardware depends upon the particular application and design constraints imposed on the solution. Those skilled in the art may implement the described functionality using different approaches for each particular application in conjunction with the embodiments, but such implementation decisions should not be interpreted as causing a departure from the scope of the present application.

The night security method provided by the embodiment of the application is explained in detail below by taking electronic equipment as an intelligent watch as an example.

In the embodiment of the application, the night security module can be used for acquiring the first information and judging whether to start the night security module currently based on the first information. The first information may include one or more of time information and position information from a timer and a positioning service, an ambient light level from a light intensity sensor drive, and movement distance information from an acceleration sensor ACC and a positioning service. After the night safe mode is turned on, the electronic device may acquire the ambient light level driven by the light intensity sensor and determine the first brightness based on the ambient light level. The electronic device may then acquire a first frequency in the algorithm library that is acquired based on the motion algorithm or the audio algorithm. After the first brightness and the first frequency are obtained, the night security module may send a schedule change request to the brightness adjustment, and after the brightness adjustment receives the request from the night security module, the LCD may be controlled to flash according to the first brightness and the first frequency. It should be noted that the electronic device may include the wearable device described in the above embodiments.

An exemplary workflow of the software of the electronic device 100 is described below in conjunction with a schematic software architecture of the electronic device 100.

In connection with the software framework schematic of the electronic device shown in fig. 6, fig. 7 provides a flow schematic of another method of flashing light. The method may include, but is not limited to, the steps of:

the electronic device may include a UI application layer, an application framework layer, an algorithm layer, and a kernel layer. The application framework layer may include, among other things, a night security module. For specific description, reference may be made to the related description in fig. 7, and details are not repeated.

S701 to S705 are operations for starting the night security mode, and are specifically described below:

s701, the kernel layer sends first information to the night security module.

The kernel layer sends first information to the night security module, and correspondingly, the night security module receives the first information from the kernel layer.

In one possible implementation, the night security module may periodically send request information for obtaining the first information to the kernel layer, and after the kernel layer receives the request information for obtaining the first information, the night security module may send the first information to the night security module.

In another possible implementation, the kernel layer may periodically collect the first information and send it to the night security module.

The description of the first information may refer to S201 and the related description in fig. 6, which are not repeated.

S702, the night security module determines to start a night security mode based on the first information.

After the night security module receives the first information from the kernel layer, the night security module may determine whether to initiate a night security mode based on the first information. The process of determining whether to start the night security mode may refer to the related descriptions of the condition 1, the condition 2 and the condition 3 in S201, which will not be described in detail.

S703, the night security module sends a night security mode starting instruction to the UI application layer.

The night security module may send a command to the UI application layer to start the night security mode if the start of the night security mode is determined. Correspondingly, the UI application layer receives an instruction for starting the night security mode from the night security module.

S704, the UI application layer displays information for starting the night security mode.

Under the condition that the UI application layer receives the night security mode starting instruction from the night security module, information for starting the night security mode can be displayed. Reference may be made specifically to the relevant description of fig. 4, and no further description is given.

And S705, the UI application layer sends a starting instruction to the night security module.

The UI application layer may perform a touch operation on the display screen (as shown in fig. 4) when displaying information for starting the night security mode, and may send a start instruction to the night security module in response to the user operation when the user clicks a control for determining to start the night security mode. Correspondingly, the night security mode may receive a start instruction from the UI application layer.

Under the condition that the night security module acquires the starting instruction, the wearable device can execute the operation in the night security mode, specifically, the steps S706 to S710.

S706, the kernel layer sends the ambient light brightness to the night security module.

Under the condition that the night security module acquires the starting instruction, the kernel layer sends the ambient light brightness to the night security module, and correspondingly, the night security module can receive the ambient light brightness from the kernel layer.
