Secondly, some terms involved in the embodiments of the present application are explained to facilitate easy understanding by those skilled in the art.

It should be noted that the screen wake-up instruction involved in the following embodiments of the present application is used to indicate an instruction generated after responding to a user operation to light up the screen of the wearable device 100. When the wearable device 100 is in the off-screen state, the user touches, for example, taps any area or a designated area of the wearable device 100, or when the user lifts or turns the wrist, the wearable device 100 will generate a screen wake-up command to light up the screen , Where the designated area is any screen area preset to respond to user touch operations. The screen wake-up command can be a screen wake-up command generated when the user touches any screen area of the wearable device 100, it can also be a screen wake-up command generated when the user touches a specified screen area of the wearable device 100, or the user lifts up or turns over. The screen wake-up command generated by the wrist is not limited to specific user operations in this embodiment of the application.

The user operations involved in the embodiments of this application include, but are not limited to, click operations, double-click operations, double-click operations, pressing operations, multiple pressing operations, sliding operations, wrist-turning operations, or a combination of at least two user operations among the above user operations. For example, the combined operation of pressing + turning the wrist.

The screen wake-up command in the embodiment of the present application includes a first screen wake-up command and a second screen wake-up command, where the first screen wake-up command is generated based on any user operation preset for waking up the screen of the wearable device 100 The second screen wake-up command is an instruction generated based on any user operation other than the touch operation corresponding to the first screen wake-up command for waking up the screen of the wearable device 100.

It is understandable that the first screen wake-up command may be a screen wake-up command generated by a preset user operation in the normal mode. For example, the user operation corresponding to the first screen wake-up command includes wrist raising operation, wrist turning operation, Click operation, touch operation, etc. The above-mentioned second screen wake-up command may be a screen wake-up command generated by a user operation different from the normal mode in the anti-mistouch mode. For example, the user operation corresponding to the second screen wake-up command includes a double-click operation, a double-click operation, and multiple One-time pressing operation, sliding operation, combined operation of raising wrist + pressing, etc.

The display control method provided by the embodiment of the present application will be described in detail below based on the wearable device 100 shown in FIG. 1 in conjunction with other drawings.

In some application scenarios, the screen wake-up of the wearable device 100, such as smart bracelets, smart watches, etc., is mainly achieved by touching or pressing the screen, raising the wrist, etc. There are certain shortcomings. For example, when the user sleeps at night, it is easy to be accidentally pressed or touched by the user or the person next to the pillow, thereby waking up the screen of the wearable device 100, especially when the user turns on the function of lifting the wrist of the wearable device 100 to brighten the screen. Later, even if the user turns over, it is possible to wake up the screen. During the night sleep period, repeated lighting of the screen will affect the user's sleep and increase the power consumption of the wearable device 100. How to improve the recognition accuracy of screen wake-up actions, avoid false triggering of the bright screen, reduce the power consumption of the wearable device due to repeated bright screens, and reduce the impact on the user's sleep quality, is a major technology that needs to be solved at present problem.

In the prior art, in order to prevent users from being disturbed during sleep at night, most wearable devices 100 are provided with a do not disturb mode. After the user turns on the Do Not Disturb mode, incoming call information and notification information such as WeChat notifications, QQ notifications, etc. will not trigger the vibration of the wearable device 100, and the screen will not turn on when the user lifts the wrist. Currently, there are two ways to turn on the do not disturb mode of the wearable device 100: (1) turn on the do not disturb mode within a specified time period; for example, the user sets to turn on the do not disturb mode within a specific time period; or keep the do not disturb mode on until the user turns off. (2) Smart on; when recognizing that the user is in a sleep state, the wearable device 100 stops receiving information notifications.

However, both of these two methods of enabling the DND mode have shortcomings. For example, for the first method of enabling the DND mode, on the one hand, the designated time period is to enable the DND mode within the time period set by the user. , Not smart enough; on the other hand, when the Do Not Disturb mode is turned on, it only prevents interference from external information such as incoming call information, WeChat notifications, QQ notifications, or lifting the wrist to brighten the screen. It cannot solve the accidental touch by yourself or the person next to the pillow at night. Mispressing, etc. cause interference from the bright screen event. As for the second method of turning on the Do Not Disturb mode, although it can intelligently turn on the Do Not Disturb mode according to the user's sleep state, on the one hand, turning on the Do Not Disturb mode is only to prevent the interference of external information, and it cannot Solve the interference caused by accidental touches and presses by yourself or the person next to the pillow at night that cause the screen-on event; on the other hand, the activation of the Do Not Disturb mode is activated when the user's current sleep state is recognized as the sleep state , But in fact, when the user’s current sleep state is the stage of preparing to fall asleep, that is, when the user is about to fall asleep, the user is more likely to be disturbed by the bright screen of the wearable device 100. For users who have difficulty falling asleep, their sleep is seriously affected. quality.

The embodiment of the present application provides a display control method, which can effectively reduce the repeated lighting of the screen caused by the user's misoperation and increase the power consumption of the wearable device 100, and prevent the repeated lighting of the screen caused by the user's misoperation from affecting the user's sleep. Improve user experience.

Please refer to FIG. 2, which is a schematic flowchart of a display control method provided by an embodiment of the present application. As shown in Figure 2, the method includes steps S101 to S105.

S101. The wearable device 100 receives a first screen wake-up instruction.

In the embodiment of the present application, after the user touches any screen area or designated screen area of the wearable device 100, or the user raises or turns the wrist, the wearable device 100 will receive a screen wake-up instruction to wake up the screen for the user to perform corresponding operations.

S102. The wearable device 100 determines the current sleep state of the user.

S103. The wearable device 100 determines whether the current sleep state of the user meets a preset condition.

S104: If the user's current sleep state does not meet the preset condition, the wearable device 100 executes a first screen wake-up instruction to light up the screen of the wearable device 100.

The sleep state in the embodiment of the present application includes three states of not entering sleep, entering sleep, and preparing to enter sleep. Determining the user’s current sleep state is to determine whether the user’s current sleep state is not in sleep state, is in sleep state, or is ready to enter sleep state. By determining the user’s sleep state, you can determine whether the user’s current sleep state is not in sleep state When entering the sleep state, the first screen wake-up instruction is directly executed to light up the screen of the wearable device 100; and when the user's current sleep state is entered or is about to enter the sleep state, the second screen wake-up instruction is required to Light up the screen of the wearable device 100 to reduce the repeated lighting of the screen caused by the user's misoperation in these two sleep states. Increase the power consumption of the wearable device 100 and prevent the repeated lighting of the screen caused by the user's misoperation from affecting the user Sleep, improve user experience.

S105. If the user's current sleep state meets the preset condition, the wearable device 100 lights up the screen after receiving the second screen wake-up instruction.

In the implementation of this application, the current sleep state of the user meets the preset condition, specifically refers to that the current sleep state of the user is considered to meet the preset condition when the user's current sleep state is entered or is about to enter the sleep state.

During night sleep, for a user whose current sleep state is ready to enter the sleep state, if any screen area or designated screen area of the wearable device 100 is touched unintentionally, or when the user raises his wrist when turning over, the wearable device 100 Just execute the screen wake-up command generated by these user operations, especially when the user has turned off the light and the wearable device is currently in a very dark environment, light up the wearable device 100 screen, suddenly bright The screen will irritate the eyes of a user in the dark, and while causing eye discomfort, it may also affect the user's sleep quality. In particular, for users who have difficulty falling asleep, such as users who have difficulty falling asleep as long as the light is affected, the sudden or repeated lighting of the screen will seriously affect the quality of their sleep, making the user perceive the wearable device 100 to brighten the screen, or Viewing or browsing the display content of the wearable device 100 after the screen of the wearable device 100 is turned on can easily make it more difficult for users who have difficulty falling asleep to enter the sleep state, which makes the user experience very bad. In addition, the repeated lighting of the screen caused by the user's misoperation also increases the power consumption of the wearable device 100 and reduces the standby time of the wearable device 100.

In some embodiments, after the wearable device 100 determines that the user’s current sleep state is entered or is about to enter the sleep state, the user operation corresponding to the generated screen wake-up instruction is regarded as a misoperation, and the screen is blocked The wake-up command does not light up the screen, which can effectively reduce the discomfort caused to the user by the user's misoperation and light the screen, and effectively reduce the power consumption of the wearable device 100 due to repeated lighting of the screen, and prevent the user from misusing the screen. Repeated screen lighting caused by operation affects the user's sleep. At this time, if the user also wants to wake up the screen of the wearable device 100, he needs to light up the screen through a screen wake-up command (ie, a second screen wake-up command) generated based on another user's operation, so as to facilitate the operation with the previous user. The generated screen wake-up instructions (ie, the first screen wake-up instructions) are distinguished, so that the user can still pass another user after the wearable device 100 determines that the user’s current sleep state is the sleep state or is about to enter the sleep state. The screen wake-up command generated by the operation is used to light up the screen of the wearable device 100, which meets the diversified needs of the user and improves the user experience.

In other implementations, after the wearable device 100 determines that the user’s current sleep state is already in sleep state or ready to enter the sleep state, or after the wearable device 100 has turned on the anti-mistouch mode, it is possible that the user still tries to Turn on the screen of the wearable device 100 to check the time or browse other content. At this time, if the screen wake-up command generated by the user operation is determined to be an invalid command, that is, the screen wake-up command generated by the current user operation is shielded, and the screen of the wearable device 100 is not lit, it may cause the user device to be broken or malfunction. The illusion of a problem reduces the user experience. In order to avoid this situation, the wearable device 100 will further detect whether the second screen wake-up instruction is received after determining that the current sleep state of the user is the sleep state or is about to enter the sleep state in the embodiment of the present application. A screen wake-up instruction corresponds to an instruction generated by another user operation after a user operation. If a second screen wake-up instruction is detected, the wearable device 100 will execute the second screen wake-up instruction to light up the screen of the wearable device 100. It is convenient for the user to view the display content of the wearable device 100, meets the diversified needs of the user, and improves the user experience.

In this embodiment of the application, the user’s current sleep state is determined after receiving the first screen wake-up instruction; if the user’s current sleep state meets the preset conditions, the wearable device 100 is turned on after the second screen wake-up instruction is received. The screen can effectively reduce the repeated lighting of the screen caused by the user's misoperation, increase the power consumption of the wearable device 100, increase the standby time of the wearable device 100, and reduce the repeated lighting of the screen caused by the misoperation to the user The adverse effects, such as eye discomfort, affecting sleep quality, etc., improve the user experience.

Table 1

In this embodiment of the application, the user’s wrist posture data is used to determine the corresponding action level, and the acceleration of the user’s wrist movement can be used to obtain the wearable device 100’s performance over a period of time through the three-axis acceleration sensor. _{N pieces of acceleration data (acceleration ACC xn} , ACC _yn , ACC _{zn in the} three directions of the x, y, and z axes) to determine the action level corresponding to the user's wrist posture data, which can be specifically obtained by calculation The mean value and variance of the root mean square of the N acceleration data, or the median of the root mean square of the N acceleration data is obtained, and the action level corresponding to the user's wrist posture data is determined.

In some specific embodiments, when the wearable device 100 receives the first screen wake-up instruction, it obtains acceleration data at the receiving time point (the time point when the first screen wake-up instruction is received), and at the receiving time point N-1 acceleration data in the previous period of time (that is, assuming that the acquired wearable device has N acceleration data in the time range from the receiving time point and a period of time before the receiving time point), calculate the obtained acceleration data The average value of the root mean square of the N acceleration data is obtained, and the calculated average value is matched with the value corresponding to the average value in the numerical table corresponding to the action level. According to the matching result, the user's wrist posture data corresponding to the Action level.

The above preset time range is within the time range where the above receiving time point is the end time, and the time point of a specific length of time before the push is the starting time. For example, the receiving time point is 08:00:00 (eight o'clock in the morning), before the push The time of 10s is 08:00:10 (eight ten seconds in the morning), and the acceleration data of the wearable device 100 in the time period of [08:00:00, 08:00:10] is acquired.

In other specific embodiments, the variance of the root mean square of the acquired N acceleration data can also be calculated to obtain a variance, and the calculated variance can be matched with the value corresponding to the variance in the value table corresponding to the action level. , Determine the action level corresponding to the user's wrist posture data according to the matching result.

In other specific embodiments, after obtaining N pieces of acceleration data, the median of the root mean square of the N pieces of acceleration data may be obtained, and this median may be used as the first value and the value corresponding to the action level. The value corresponding to the median in the table is matched, and the action level corresponding to the user's wrist posture data is determined according to the matching result.

In order to improve the accuracy of determining the action level corresponding to the user's wrist posture data, the embodiment of the present application determines at least two corresponding action levels based on the obtained user's wrist posture data; the at least two corresponding action levels Perform comparison; if there are at least two action levels with the same level in the at least two corresponding action levels, the action level with the same number of levels is set as the action level corresponding to the user's wrist posture data.

In some specific embodiments, after determining at least two action levels of the user’s current wrist according to any two or more of the mean, variance, or median in the foregoing embodiments, the determined action Levels are compared. If there are at least two action levels with the same level in the at least two corresponding action levels, the action level with the same number of levels is set as the action level corresponding to the user’s wrist posture data, for example, OK When the two action levels corresponding to the user's wrist posture data are two, if the two action levels are the same, the action level corresponding to the two consistent action levels is taken as the action level corresponding to the user's wrist posture data; Otherwise, reacquire N acceleration data to determine the action level corresponding to the user's wrist posture data. If the two action levels corresponding to the determined user's wrist posture data are more than two, if the action levels with the same number of the two or more action levels account for the total number of action levels corresponding to the user’s current wrist posture data When the ratio reaches the preset threshold, the action level with the same number of levels is set as the action level corresponding to the user's wrist posture data. Otherwise, N acceleration data are re-acquired to determine the user’s wrist posture data. Action level. Alternatively, the user's action level is further determined by the motion range of the user's wrist, and the obtained action levels are compared, and the action level corresponding to the user's wrist posture data is determined according to the comparison result.

For example, in some specific embodiments, by acquiring the data of the acceleration sensor 180E or the gyroscope sensor 180B, and the distance sensor 180F, the movement amplitude of the user's wrist is determined, that is, the user's wrist is between a certain reference point distance or angle The moved value. After determining the movement amplitude of the user's wrist, compare it with the preset amplitude value. If the determined movement amplitude of the user's wrist is less than the preset amplitude value, it is determined that the user's movement amplitude is small; if the determined user's wrist is If the movement amplitude of the user is greater than or equal to the preset amplitude value, it is determined that the user's movement amplitude is relatively large. According to the determined magnitude of the user's motion amplitude, the corresponding action level is determined.

In the embodiment of the present application, the action level corresponding to the user's wrist posture data is determined according to the user's wrist posture data; if the determined action level corresponding to the user's wrist posture data is a preset action level, such as the above At level 0 or 1, it is determined that the user's wrist posture data meets the first condition.

For example, when the user's wrist posture data corresponds to an action level of level 0, the user's current sleep state can be considered to have entered a sleep state, and when the user's wrist posture data corresponds to an action level of level 1, it can be considered that the user is currently sleeping The state is ready to go to sleep. When the action level corresponding to the user's wrist posture data is level 2 or above, it can be considered that the user's current sleep state is not entering the sleep state.

When the ambient light brightness of the environment where the wearable device 100 is currently located is not lower than the preset brightness threshold, even if the screen of the wearable device 100 is turned on, it will not cause discomfort to the user’s eyes, but it will also increase the wearable device 100’s Therefore, the ambient light brightness of the environment in which the wearable device is currently located is not lower than the preset brightness threshold, but when the user's wrist posture data meets the first condition, it is convenient for the user to view the wearable device 100 The display content of the screen still needs to use the second screen wake-up command to light up the screen of the wearable device 100, so as to reduce the repeated screen lighting caused by the user's misoperation, increase the power consumption of the wearable device 100, and extend the wearable device 100's power consumption. Standby time.

In some embodiments, determining the user's current sleep state can also be determined by physiological characteristic parameters such as heart rate and breathing. For example, by judging whether the user's heart rate is lower than a preset heart rate value, whether the number of breaths within a preset time is lower than a preset number, and so on.

It is understandable that when the user’s current sleep state is entered the sleep state, in order to reduce the repeated lighting of the screen caused by the user’s misoperation and increase the power consumption of the wearable device 100, the user’s current sleep state is entered the sleep state After that, generally the first screen wake-up command is directly shielded. If the user suddenly wakes up and wants to light up the screen, he needs to use the second screen wake-up instruction to light up the screen, so that the wearable device can distinguish the screen wake-up operations performed by the user during different sleep stages, and improve the user experience.

This embodiment of the application determines whether the user’s current sleep state meets the preset brightness threshold by determining whether the acquired user’s wrist posture data meets the first condition and whether the ambient light brightness of the environment where the wearable device 100 is currently located is lower than a preset brightness threshold. Set conditions, that is, to determine whether the user’s current sleep state is already in sleep state or ready to enter sleep state, which can effectively improve the accuracy of judging whether the user operation corresponding to a screen wake-up command is a misoperation, so as to achieve better prevention Mistakenly touch the purpose.

It should be noted that, due to the limitations of the wearable device 100, when determining the user’s current sleep state, it may not be able to quickly and accurately determine whether the user is currently in the suspected falling asleep stage or falling asleep stage. After the first screen wake-up instruction, a sleep stage confirmation request instruction can be sent to a third-party electronic device, such as a smart phone bound to the wearable device 100. The sleep stage confirmation request instruction is used to instruct the third-party electronic device to determine the user's current sleep The third-party electronic device feeds back the judgment result to the wearable device 100, that is, the execution subject of the foregoing steps S501 to S503 may be other electronic devices other than the wearable device 100.
