Next, some terms involved in the embodiments of the present application are explained for easy understanding by those skilled in the art.

It should be noted that, the following embodiments of the present application relate to a screen wake instruction for indicating an instruction generated in response to a user operation to light a screen of the wearable device 100. When the wearable device 100 is in the off-screen state, the user touches, for example, clicking, any area of the wearable device 100 or a designated area, or when the user lifts or turns over the wrist, the wearable device 100 generates a screen wake-up instruction to light up the screen, wherein the designated area is any screen area preset for responding to the touch operation of the user. The screen wake-up instruction may be a screen wake-up instruction generated when a user touches any screen area of the wearable device 100, or may be a screen wake-up instruction generated when the user touches a specified screen area of the wearable device 100, or may be a screen wake-up instruction generated when the user lifts or turns over the wrist.

The user operation according to the embodiment of the present application includes, but is not limited to, a click operation, a double click operation, a continuous click operation, a press operation, a multiple press operation, a slide operation, a wrist turning operation, or a combination operation of at least two of the above user operations, such as a press+wrist turning operation.

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

It may be understood that the first screen wake-up instruction may be a screen wake-up instruction generated by a preset user operation in a normal mode, for example, the user operation corresponding to the first screen wake-up instruction includes a wrist lifting operation, a wrist turning operation, a clicking operation, a tapping operation, and the like. The second screen wake-up instruction may be a screen wake-up instruction generated by a user operation different from the normal mode in the false touch prevention mode, for example, the user operation corresponding to the second screen wake-up instruction includes a double click operation, a continuous click operation, a multiple press operation, a sliding operation, a wrist lifting and press combination operation, and the like.

The following describes in detail a display control method provided by an embodiment of the present application based on the wearable device 100 shown in fig. 1 with reference to other drawings.

In some application scenarios, the wearable device 100, such as a smart bracelet, a smart watch, etc., mainly performs the actions of touching or pressing the screen, lifting the wrist, etc., to light the screen, and although the screen can be quickly awakened, certain disadvantages exist. For example, when the user is sleeping at night, the user may easily wake up the screen of the wearable device 100 because the user may press or touch the screen by himself or herself or by a person at the pillow, and especially after the user turns on the function of the wrist-lifting and screen-lighting of the wearable device 100, even if the user turns over, the user may wake up the screen. While repeated lighting during night sleep affects the user's sleep and also increases the power consumption of the wearable device 100. How to improve the recognition accuracy of the screen awakening action, avoid the false triggering of the bright screen, reduce the power consumption of the wearable equipment increased by repeated bright screen, and reduce the influence on the sleeping quality of the user is a great technical problem to be solved at present.

In the prior art, in order to prevent the user from being disturbed during night sleep, a tamper-free mode is provided on most wearable devices 100. After the user starts the no-disturbance mode, incoming call information, notification information such as WeChat notification, QQ notification and the like cannot trigger vibration of the wearable device 100, and a user cannot lighten a screen when lifting the wrist. There are two methods for opening the no-disturb mode of the wearable device 100 at present: (1) a specified time period is started; for example, a user sets to start a no-disturbance mode in a specific time period; or the do-not-disturb mode is turned on until the user turns off. (2) intelligent starting; upon recognizing that the user is in the sleep state, the wearable device 100 stops receiving the information notification.

However, the two methods for starting the no-disturbance-rejection mode have disadvantages, for example, for the first method for starting the no-disturbance-rejection mode, on the one hand, the starting of the specified time period is to start the no-disturbance-rejection mode in the time period set by the user, which is not intelligent enough; on the other hand, after the no-disturbance mode is started, only the interference of external information such as incoming call information, weChat notification, QQ notification or wrist lifting and screen lightening is prevented, and the interference of screen lightening events caused by accidental false touch, false pressing and the like of the user at night or at the pillow side cannot be solved. For the second method for starting the no-disturbance mode, although the no-disturbance mode can be intelligently started according to the sleep state of the user, on one hand, the no-disturbance mode is started only to prevent the interference of external information, and the interference of bright screen events caused by accidental false touch, false pressing and the like of the user at night or by the people at the pillow side cannot be solved; on the other hand, the non-disturbing mode is started when the current sleep state of the user is identified as the sleep state, but actually, when the current sleep state of the user is the sleep stage, i.e. the user is in a state of sleeping or not, the user is more easily disturbed by the bright screen of the wearable device 100, and for the user with difficulty in sleeping, the sleep quality of the user is seriously affected.

The embodiment of the application provides a display control method, which can effectively reduce the power consumption of the wearable device 100 increased by repeated screen lighting caused by misoperation of a user, prevent the repeated screen lighting caused by misoperation of the user from influencing the sleep of the user and improve the use experience of the user.

Referring to fig. 2, fig. 2 is a flow chart of a display control method according to an embodiment of the application. As shown in fig. 2, the method includes steps S101 to S105.

S101, the wearable device 100 receives a first screen wake instruction.

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

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

S103, the wearable device 100 judges whether the current sleep state of the user meets preset conditions.

And S104, if the current sleep state of the user does not meet the preset condition, the wearable device 100 executes a first screen wake-up instruction, and the screen of the wearable device 100 is lightened.

The sleep states in the embodiment of the application comprise three states of non-sleep, sleep and ready to go to sleep. Determining the current sleep state of the user is to determine whether the current sleep state of the user is a non-entered sleep state or a entered sleep state or is ready to enter the sleep state, and by determining the sleep state of the user, the first screen wake-up instruction can be directly executed when the current sleep state of the user is the non-entered sleep state, so as to light up the screen of the wearable device 100; when the current sleep state of the user is the sleep state or the sleep state is ready to be entered, the screen of the wearable device 100 needs to be lightened through a second screen wake-up instruction, so that the power consumption of the wearable device 100 is reduced, the repeated screen lightening caused by misoperation of the user in the two sleep states is increased, the influence of the repeated screen lightening caused by misoperation of the user on the sleep of the user is prevented, and the use experience of the user is improved.

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

In the embodiment of the application, the current sleep state of the user meets the preset condition, specifically, when the current sleep state of the user is the entered sleep state or is ready to enter the sleep state, the current sleep state of the user can be considered to meet the preset condition.

During night sleep, if a user in a current sleep state is ready to enter the sleep state, if the user inadvertently touches any screen area or designated screen area of the wearable device 100, or lifts the wrist when turning over the user, the wearable device 100 executes a screen wake-up instruction generated by these user operations, especially in the case that the environment where the user has turned off the light, i.e. the environment where the wearable device is currently located is very dark, the screen of the wearable device 100 is lightened, and the eyes of the user in the dark are stimulated by the bright screen between the sudden touch, and the sleeping quality of the user may be affected while causing discomfort to the eyes. In particular, for a user who is difficult to fall asleep, for example, a user who is difficult to fall asleep as long as the user has a bright effect, the sleep quality of the user is seriously affected by suddenly or repeatedly lighting the screen, so that the user can easily see or browse the display content of the wearable device 100 after perceiving that the wearable device 100 is on the screen, the user who is originally difficult to fall asleep is easily caused to be more difficult to enter a sleep state, and the user experience is very bad. In addition, repeated screen lighting caused by misoperation of the user also increases power consumption of the wearable device 100, and reduces standby time of the wearable device 100.

In some embodiments, after determining that the current sleep state of the user is the sleep state or is ready to enter the sleep state, the wearable device 100 considers the user operation corresponding to the generated screen wake-up instruction as an incorrect operation, and shields the screen wake-up instruction, so that the screen is not lightened, discomfort caused by the fact that the user is wrongly operated to lighten the screen can be effectively reduced, the power consumption of the wearable device 100 increased due to repeated screen lightening is effectively reduced, and the influence of the repeated screen lightening caused by the incorrect operation of the user on the sleep of the user is prevented. At this time, if the user wants to wake up the screen of the wearable device 100, the screen needs to be lightened by a screen wake-up instruction (i.e. a second screen wake-up instruction) generated based on another user operation, so as to distinguish from a screen wake-up instruction (i.e. a first screen wake-up instruction) generated by a previous user operation, so that after the wearable device 100 determines that the current sleep state of the user is the sleep state or is ready to enter the sleep state, the user can still lighten the screen of the wearable device 100 by the screen wake-up instruction generated by another user operation, thereby satisfying diversified requirements of the user and improving the use experience of the user.

In other implementations, after determining that the user's current sleep state is entered or is ready to enter a sleep state, or after wearable device 100 has turned on the anti-false touch mode, it is possible that the user still wants to illuminate the screen of wearable device 100 to view time or view other content. At this time, if the screen wake-up instruction generated by the user operation is determined to be an invalid instruction, that is, the screen wake-up instruction generated by the current user operation is masked, the screen of the wearable device 100 is not lightened, and the illusion that the user device is bad or has a problem is possibly given, so that the use experience of the user is reduced. In order to avoid this, after determining that the current sleep state of the user is the sleep state or is ready to enter the sleep state, the wearable device 100 in the embodiment of the application further detects whether a second screen wake-up instruction is received, that is, an instruction generated by another user operation after the user operation corresponding to the first screen wake-up instruction, if the second screen wake-up instruction is detected, the wearable device 100 will execute the second screen wake-up instruction, and the screen of the wearable device 100 is lightened, so that the user can conveniently view the display content of the wearable device 100, the diversified requirements of the user are met, and the use experience of the user is improved.

After receiving a first screen awakening instruction, the embodiment of the application determines the current sleep state of the user; if the current sleep state of the user meets the preset condition, the screen of the wearable device 100 is lightened after the second screen awakening instruction is received, so that the power consumption of the wearable device 100 can be effectively reduced, the power consumption of the wearable device 100 is increased due to repeated screen lightening caused by misoperation of the user, the standby time of the wearable device 100 is prolonged, adverse effects, such as discomfort of eyes, influence on sleep quality and the like, caused by repeated screen lightening caused by misoperation of the user are reduced, and the user experience is improved.

Referring to fig. 3, fig. 3 is a flow chart of another display control method according to an embodiment of the application. As shown in fig. 2, the method includes steps S201 to S204.

S201, the wearable device 100 receives a first screen wake instruction.

S201 may be described with reference to step S101 in the embodiment described in fig. 2, and will not be described herein.

S202, the wearable device 100 detects the current screen state.

S203, if the current screen state of the wearable device 100 is in the off-screen state, determining the current sleep state of the user.

In an embodiment of the present application, the current screen state of the wearable device 100 includes a bright screen state and a dead screen state. When the screen state of the wearable device 100 is in the bright screen state, the first screen wake-up instruction can be directly executed, and the screen of the wearable device 100 is lightened, so that a user can conveniently and quickly browse or view corresponding display contents. When the screen state of the wearable device 100 is in the off-screen state, it is necessary to avoid the bright screen caused by the misoperation of the user corresponding to the first screen wake-up instruction, and the current sleep state of the user can be determined to improve the accuracy of judging the repeated bright screen caused by the misoperation of the user, so as to achieve the purposes of reducing the power consumption of the wearable device increased by the repeated bright screen caused by the misoperation of the user and preventing the repeated bright screen caused by the misoperation of the user from affecting the sleep of the user.

S204, if the current sleep state of the user meets the preset condition, the wearable device 100 lights up the screen after receiving the second screen wake-up instruction.

S204 may be described with reference to step S105 in the embodiment described in fig. 2, and will not be described herein.

Referring to fig. 4, fig. 4 is a flow chart of another display control method according to an embodiment of the application. As shown in fig. 4, the method includes steps S301 to S304.

S301, the wearable device 100 receives a first screen wake instruction. S301 may be described with reference to step S101 in the embodiment described in fig. 2, and will not be described herein.

S302, the wearable device 100 determines whether the anti-false touch mode is on.

The above-mentioned error touch prevention mode is a preset mode for preventing user from misoperation, in the error touch prevention mode, the user needs more complicated operations such as double click, continuous click, sliding and the like to light the screen, but simple click operation, wrist lifting operation and the like cannot light the screen.

In the embodiment of the present application, a user may set the anti-false touch mode to be on in a specified time period, for example, 22:00 to 7:00 a next day, when the anti-false touch mode of the wearable device 100 is on, and when the wearable device 100 is in a screen-off state in the specified time period, if the user does not touch any screen area or specified screen area of the wearable device 100 or the user lifts or turns the wrist, the wearable device 100 will detect a screen wake-up instruction generated based on the current user operation, and at this time, the wearable device 100 will need to determine whether the user operation corresponding to the screen wake-up instruction is the preset user operation, and if so, the screen is turned on. Otherwise, the user operation corresponding to the first screen wake-up instruction is determined to be misoperation, the screen wake-up instruction is shielded, and the screen of the wearable device 100 is not lightened, so that the screen is prevented from being lightened due to misoperation of the user.

The preset user operation is a preset operation for waking up the screen in the anti-false touch mode, such as a double-click, a continuous-click or a multiple-press operation on any area or a designated area of the screen, a sliding operation performed on any area or designated area of the screen, a pressing and wrist lifting combination operation, and the like.

S303, if the anti-false touch mode is not turned on, the wearable device 100 determines the current sleep state of the user.

S304, if the current sleep state of the user meets the preset condition, the wearable device 100 lights up the screen after receiving the second screen wake-up instruction.

S304 may be described with reference to step S105 in the embodiment described in fig. 2, and will not be described herein.

According to the embodiment of the application, whether the false touch prevention mode is started is determined, so that whether the current stage of the user is required to be determined to trigger the automatic false touch prevention function is determined, the intelligent degree of the wearable equipment is improved, and different requirements of people are met.

Referring to fig. 5, fig. 5 is a flowchart illustrating another display control method according to an embodiment of the application. As shown in fig. 4, the method includes steps S401 to S403.

S401, if the current sleep state of the user meets the preset condition, the wearable device 100 detects whether a second screen wake-up instruction is received.

S402, if the second screen wake-up instruction is received, the wearable device 100 executes the second screen wake-up instruction, and lights up the screen of the wearable device 100.

S403, if the second screen wake-up instruction is not received within the predetermined time, the wearable device 100 recognizes the user operation corresponding to the first screen wake-up instruction as an error operation, shields the first screen wake-up instruction, and does not light the screen of the wearable device 100.

In the embodiment of the present application, when the wearable device 100 is in the off-screen state, when the user clicks or presses the screen of the wearable device 100 for the first time, the wearable device 100 will detect a first screen wake-up instruction generated based on the clicking or pressing operation of the user, at this time, after judging that the current sleep state of the user is the sleep state or ready to enter the sleep state, the wearable device 100 will not execute the first screen wake-up instruction temporarily, and continuously detect whether the user acts on the screen of the wearable device 100 through operations such as sliding, double clicking, continuous clicking and the like for the second time within a predetermined time, for example, 5 seconds, that is, the wearable device 100 detects whether a second screen wake-up instruction generated based on another user operation such as sliding, continuous clicking, double clicking and the like of the user is received within the predetermined time, and if the second screen wake-up instruction is received within the predetermined time, the wearable device 100 may execute the first screen wake-up instruction to light the screen, and may execute the second screen wake-up instruction to light the screen. If the second screen wake-up instruction is not received within the predetermined time, the wearable device 100 recognizes that the user operation corresponding to the first screen wake-up instruction is an incorrect operation, shields the first screen wake-up instruction, and does not light the screen of the wearable device 100.

The embodiment of the application determines whether to lighten the screen of the wearable device 100 by judging whether the second screen awakening instruction is received or not so as to reduce the occurrence of repeated screen lightening events caused by misoperation of a user, effectively reduce discomfort brought to the user by lightening the screen caused by misoperation of the user and effectively reduce the power consumption of the wearable device 100 increased by repeated screen lightening of the wearable device.

In the embodiment of the present application, when the wearable device 100 determines the current sleep state of the user, sleep detection data is acquired, and the current sleep state of the user is determined according to the sleep detection data.

It should be noted that the sleep detection data is related detection data for determining a current sleep state of the user, and includes, but is not limited to, at least one of physiological characteristic data of the user, movement posture data of the user, and current environment data. Wherein the physiological characteristic data of the user comprises, but is not limited to, heart rate, pulse, respiratory rate, brain wave signals and the like of the user; the motion gesture data of the user includes, but is not limited to, wrist gesture data of the user; the current environmental data includes, but is not limited to, ambient light level data of the environment in which the wearable device 100 is currently located.

The sleep detection data can be used for judging whether the current sleep state of the user is the non-sleep state, the sleep state or the sleep state ready to be entered. Further judging whether the user operation corresponding to the first screen instruction needs to be judged as misoperation or not, if the user operation corresponding to the first screen instruction is not misoperation, the wearable device 100 can execute a first screen awakening instruction, and a screen of the wearable device 100 is lightened; otherwise, another screen wake-up instruction, namely a second screen wake-up instruction, is needed to light the screen of the wearable device 100, so as to achieve the purposes of reducing repeated screen lighting caused by misoperation of the user and increasing power consumption of the wearable device 100, preventing the repeated screen lighting caused by misoperation of the user from influencing sleeping of the user, and improving user experience.

It should be noted that, the current sleep state of the user can be quickly determined to be the state that does not enter the sleep state and the state that does enter the sleep state by the physiological characteristic data of the user or the movement gesture data of the user. The wearable device 10 accurately determines whether the current sleep state of the user is ready to enter the sleep state, which is a key point for improving the accuracy of determining whether the current user operation is misoperation, so that the accuracy of determining whether the sleep state of the user is ready to enter the sleep state is improved, and the accuracy of determining whether the user operation corresponding to a certain screen wake-up instruction is misoperation can be effectively improved, thereby achieving the purpose of better preventing misoperation.

Referring to fig. 6, fig. 6 is a flowchart illustrating a method for determining a current sleep state of a user according to an embodiment of the application. As shown in fig. 6, the method includes steps S501 to S503.

S501, the wearable device 100 acquires wrist gesture data of the user, and the environmental light brightness of the environment where the wearable device 100 is currently located.

In the embodiment of the present application, the wrist gesture data of the user includes, but is not limited to, acceleration data of wrist movement, distance data of wrist movement, and the like, and the wearable device 100 may acquire the wrist gesture data of the user through the acceleration sensor 180E, the gyro sensor 180B, the distance sensor 180F, and the like. The ambient light level of the environment in which the wearable device 100 is currently located may be acquired by the ambient light sensor 180L.

S502, the wearable device 100 judges whether the acquired wrist gesture data of the user meets a first condition and whether the environmental light brightness of the current environment of the wearable device 100 is lower than a preset brightness threshold.

In the embodiment of the present application, whether the obtained wrist gesture data of the user meets the first condition is specifically determined by determining whether the average value, variance, median, etc. of the root mean square obtained according to the wrist gesture data of the user obtained from the wearable device 100 within a period of time meets a corresponding preset numerical range; and judging whether the action grade corresponding to the wrist gesture data of the user is a preset action grade or not. If the average value, variance, median and the like of the root mean square obtained according to the wrist posture data of the user within a period of time meet the corresponding preset numerical range, or the action grade corresponding to the wrist posture data of the user is the preset action grade, the obtained wrist posture data of the user is determined to meet the first condition.

S503, if the acquired wrist gesture data of the user accords with a first condition and/or the environmental light brightness of the current environment of the wearable device is lower than a preset brightness threshold, determining that the current sleep state of the user accords with a preset condition.

According to the embodiment of the application, according to the wrist gesture data of the user, determining the action grade corresponding to the wrist gesture data of the user; and if the action grade corresponding to the determined wrist gesture data of the user is the preset action grade, determining that the wrist gesture data of the user meets the first condition.

In some embodiments, the wearable device 100 obtains N acceleration data ACC _xn,ACC_yn,ACC_zn in three directions of x, y and z axes of the wearable device 100 through a three-axis acceleration sensor for a period of time, where N is an integer greater than or equal to 1, N e1, N, and the corresponding first value is obtained by calculating the mean value, median value and variance value of the root mean square of N acceleration ACC _xn,ACC_yn,ACC_zn of the wearable device 100 in three directions of x, y and z axes, and then determining the action level corresponding to the wrist gesture data of the user according to dividing the first value into the value range of the corresponding action level.

In some specific embodiments, the motion levels corresponding to the wrist gesture data of the user may be divided into five levels (e.g., 0-4 levels), where level 0 indicates rest, level 1 indicates a small amount of motion or a small motion amplitude, level 2 indicates a medium motion amplitude, level 3 indicates a large amount of motion or a large motion amplitude, and level 4 indicates a large amount of motion.

In some embodiments of the present application, the action levels corresponding to the gesture data of the wrist of the user may be further divided into more or less action levels, and the more the action levels are divided, the more detailed the analysis of the gesture data of the wrist of the user, the more accurate the determined action level.

Specifically, the numerical table corresponding to the action level provided in table 1 may be referred to. Each action class corresponds to a different range of values, such as a 0-class corresponding to a first mean range such as [ a ₁,a₂ ], a first median range such as [ beta ₁,β₂), or a first variance range such as [ gamma ₁,γ₂); the range of values corresponding to level 1 is a second mean range such as [ a ₂,a₃ ], a second median range such as [ beta ₂,β₃), or a second variance range such as [ gamma ₂,γ₃), and so on.

TABLE 1

In the embodiment of the application, the corresponding action level is determined according to the wrist gesture data of the user, and the action level corresponding to the wrist gesture data of the user can be determined by the acceleration of the wrist motion of the user, that is, the N acceleration data (acceleration ACC _xn,ACC_yn,ACC_zn in the x, y and z directions) of the wearable device 100 obtained by the three-axis acceleration sensor in a period of time, specifically, the action level corresponding to the wrist gesture data of the user is determined by calculating the mean and variance of the root mean square of the N obtained acceleration data, or obtaining the median of the root mean square of the N acceleration data.

In some specific embodiments, when the wearable device 100 receives the first screen wake-up instruction, it acquires acceleration data at a receiving time point (a time point when the first screen wake-up instruction is received), and N-1 acceleration data within a period of time before the receiving time point (that is, assuming that the acquired acceleration data of the wearable device in a time range from the receiving time point and a period of time before the receiving time point is N), calculates a mean value of root mean square of the acquired N acceleration data, obtains a mean value, matches a value corresponding to the mean value in a value table corresponding to the action level, and determines the action level corresponding to the wrist posture data of the user according to a matching result.

In the preset time range, the receiving time point is taken as the ending time, and the time point of the pushing specific duration is taken as the starting time, for example, the receiving time point is 08:00:00 (eight am integer), the pushing time of 10s is 08:00:10 (eight am ten seconds), and the acceleration data of the wearable device 100 in the time period of [08:00:00,08:00:10] are obtained.

In other specific embodiments, the variance of the root mean square of the obtained N acceleration data may be calculated to obtain a variance, the calculated variance is matched with a value corresponding to the variance in a value table corresponding to the action level, and the action level corresponding to the wrist gesture data of the user is determined according to the matching result.

In other specific embodiments, after acquiring the N acceleration data, the median of the root mean square of the N acceleration data may be acquired, the median may be used as the first value to be matched with a value corresponding to the median in the value table corresponding to the action level, and the action level corresponding to the wrist posture data of the user may be determined according to the matching result.

In order to improve the accuracy of judging action grades corresponding to the wrist posture data of the user, the embodiment of the application determines at least two corresponding action grades according to the acquired wrist posture data of the user; comparing the at least two corresponding action levels; if at least two action levels with the same level exist in the at least two corresponding action levels, the action level with the largest number of the same levels is set as the action level corresponding to the wrist gesture data of the user.

In some specific embodiments, after determining at least two action levels of the current wrist portion of the user according to any two or more of the mean value, the variance, and the median in the above embodiments, comparing the determined action levels, if at least two action levels with the same level exist in the at least two corresponding action levels, setting the action level with the largest number of levels as the action level corresponding to the wrist portion posture data of the user, for example, when the determined two action levels corresponding to the wrist portion posture data of the user are two, if the two action levels are identical, taking the action level corresponding to the identical two action levels as the action level corresponding to the wrist portion posture data of the user; otherwise, acquiring N acceleration data again to determine the action grade corresponding to the wrist gesture data of the user. If the determined two action levels corresponding to the wrist posture data of the user are more than two, if the proportion of the action level with the largest quantity among the action levels with the same quantity among the action levels with the largest quantity occupies the total number of the action levels corresponding to the current wrist posture data of the user to reach a preset threshold, setting the action level with the largest quantity among the action levels with the same quantity as the action level corresponding to the wrist posture data of the user, otherwise, acquiring N acceleration data again to determine the action level corresponding to the wrist posture data of the user. Or further determining the action grade of the user according to the motion amplitude of the wrist of the user, comparing the obtained action grade, and determining the action grade corresponding to the wrist gesture data of the user according to the comparison result.

For example, in some specific embodiments, the magnitude of motion of the user's wrist, i.e., the value of the user's wrist movement between a certain reference point distance or angle, is determined by acquiring data from the acceleration sensor 180E or the gyro sensor 180B, and the distance sensor 180F. After the motion amplitude of the wrist part of the user is determined, comparing the motion amplitude with a preset amplitude value, and if the determined motion amplitude of the wrist part of the user is smaller than the preset amplitude value, determining that the motion amplitude of the user is smaller; and if the determined motion amplitude of the wrist part of the user is larger than or equal to the preset amplitude value, the motion amplitude of the user is determined to be larger. And determining a corresponding action level according to the motion amplitude of the identified user.

According to the embodiment of the application, the action grade corresponding to the wrist gesture data of the user is determined according to the wrist gesture data of the user; if the determined action level corresponding to the wrist gesture data of the user is a preset action level, for example, level 0 or level 1, then the wrist gesture data of the user is determined to meet the first condition.

For example, when the action level corresponding to the wrist posture data of the user is 0 level, the current sleep state of the user can be considered to be the sleep state, and when the action level corresponding to the wrist posture data of the user is 1 level, the current sleep state of the user can be considered to be the sleep state. When the action level corresponding to the wrist posture data of the user is 2 or more, the current sleep state of the user can be considered as not-entered sleep state.

When the environmental 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, discomfort of eyes of a user is not caused, but the power consumption of the wearable device 100 is increased, so that when the environmental light brightness of the environment where the wearable device is currently located is not lower than the preset brightness threshold, but the wrist gesture data of the user accords with the first condition, in order to facilitate the user to view the display content of the screen of the wearable device 100, the screen of the wearable device 100 still needs to be turned on through a second screen wake-up instruction, so that the power consumption of the wearable device 100 is increased due to repeated screen-on caused by misoperation of the user, and the standby time of the wearable device 100 is prolonged.

In some embodiments, determining the current sleep state of the user may also be determined by physiological characteristic parameters such as heart rate, respiration, etc. For example, whether the heart rate of the user is lower than a preset heart rate value, whether the respiration frequency in the preset time is lower than the preset frequency, and the like are judged.

It can be appreciated that, when the current sleep state of the user is the sleep state, in order to reduce the repeated screen-lighting caused by the misoperation of the user and increase the power consumption of the wearable device 100, the first screen wake-up instruction is generally directly masked after the current sleep state of the user is the sleep state. If the user wakes up suddenly and wants to lighten the screen, the screen is lightened through a second screen wake-up instruction, so that the wearable device can distinguish the screen wake-up operation of the user in different sleep stages, and the use experience of the user is improved.

According to the embodiment of the application, whether the current sleep state of the user accords with the preset condition or not is determined by judging whether the acquired wrist gesture data of the user accords with the first condition and whether the environmental light brightness of the current environment of the wearable device 100 is lower than the preset brightness threshold value or not, namely, whether the current sleep state of the user is the sleep state or is ready to enter the sleep state is determined, and the accuracy rate of judging whether the user operation corresponding to a certain screen awakening instruction is misoperation or not can be effectively improved, so that the aim of better preventing misoperation is achieved.

It should be noted that, because of the limitation of the wearable device 100, when determining the current sleep state of the user, it may not be possible to quickly and accurately determine whether the user is currently in the suspected sleep stage or the sleep stage, that is, the wearable device 100 may send a sleep stage confirmation request instruction to a third party electronic device, such as a smart phone bound to the wearable device 100, after detecting the first screen wake-up instruction, where the sleep stage confirmation request instruction is used to instruct the third party electronic device to determine the current sleep state of the user, and the third party electronic device feeds back the determination result to the wearable device 100, that is, the execution subject of steps S501 to S503 may be other electronic devices except the wearable device 100.
