The power consumption of the wearable device increased by repeated screen lightening due to misoperation of the user can be effectively reduced, the phenomenon that the user sleeps due to repeated screen lightening caused by misoperation of the user is prevented, and the user can wake up the instruction to lighten the screen quickly through the second screen when needing to check the display content of the screen of the wearable device, so that the use experience of the user is improved.

The screen wake-up instruction referred to in the embodiments of the present application is an instruction for instructing to illuminate a screen of the wearable device generated in response to a user operation. When the screen of the wearable device is in a screen-off state, when a user touches, for example, clicks any area or a designated area of the wearable device, or when the user lifts or turns over the wrist, the wearable device generates a screen wake-up command to light up the screen of the wearable device, wherein the designated area is any screen area preset for responding to the touch operation of the user. That is, the screen wake-up instruction may be a screen wake-up instruction generated when the user touches any screen region of the wearable device, may also be a screen wake-up instruction generated when the user touches a designated screen region of the wearable device, and may also be a screen wake-up instruction generated when the user lifts or turns over the wrist.

The sleep states include three states of not going to sleep, having gone to sleep, and being ready to go to sleep. The fact that the current sleep state of the user meets the preset condition specifically means that the current sleep state of the user is a sleep state already entered or a sleep state ready to enter.

According to the embodiment of the application, the current screen state of the wearable device is detected, and after the current screen state of the wearable device is determined to be in the screen off state, the current sleep state of a user is determined, so that when the current screen state of the wearable device is in the screen on state, other user operations can be responded quickly, and the response efficiency of the wearable device is improved. Only when the current screen state of the wearable device is in the screen-off state, the current sleep state of the user needs to be determined, so that the power consumption of the wearable device increased by repeatedly turning on the screen due to misoperation of the user is reduced, and the purpose that the sleep of the user is influenced by the repeatedly turning on the screen due to the misoperation of the user is prevented.

With reference to the first aspect, in a second possible implementation manner of the first aspect, after receiving the first screen wake-up instruction, the wearable device further includes: the wearable device determines whether the anti-false touch mode is started; if the false touch prevention mode is started, the wearable device determines whether the user operation corresponding to the first screen awakening instruction is a preset user operation; and if the user operation corresponding to the first screen awakening instruction is the preset user operation, executing the first screen awakening instruction, and lightening the screen of the wearable device, otherwise, determining the user operation corresponding to the first screen awakening instruction as the misoperation, shielding the first screen awakening instruction, and not lightening the screen of the wearable device. If the anti-false touch mode is not turned on, the wearable device determines the current sleep stage of the user.

According to the embodiment of the application, whether the false touch prevention mode is started or not is determined, so that whether the current stage of the user needs to be determined to trigger the automatic false touch prevention function or not is determined, namely, if the current sleep state of the user meets the preset condition is determined, the screen of the wearable device is lightened after the second screen awakening instruction is received, the intelligent degree of the wearable device is improved, and different requirements of people are met.

With reference to the first aspect, in a third possible implementation manner of the first aspect, if the current sleep state of the user meets a preset condition, lighting a screen of the wearable device after receiving the second screen wake-up instruction includes: if the current sleep state of the user meets a preset condition, detecting whether the second screen awakening instruction is received; if the second screen awakening instruction is received, executing the second screen awakening instruction, and lightening a screen of the wearable device; if the second screen awakening instruction is not received within the preset time, the user operation corresponding to the first screen awakening instruction is determined to be misoperation, the first screen awakening instruction is shielded, and the screen of the wearable device is not lightened.

The embodiment of the application determines whether to light the screen of the wearable device by judging whether to receive the second screen awakening instruction or not so as to reduce the occurrence of the event of repeated screen lightening caused by user misoperation, can effectively reduce the discomfort brought to the user by lightening the screen due to the user misoperation, effectively reduce the power consumption of the wearable device increased due to repeated screen lightening, and prevent the user sleep from being influenced by the repeated screen lightening caused by the user misoperation.

According to the embodiment of the application, whether the current sleep state of the user is the sleep state which is not entered, the sleep state which is entered or the sleep state which is ready to enter can be judged through the sleep detection data. Whether the user operation corresponding to the first screen instruction needs to be judged to be misoperation or not is further judged, and if the user operation corresponding to the first screen instruction is not misoperation, namely the current sleep state of the user does not accord with the preset condition, the wearable device can execute the first screen awakening instruction and light the screen of the wearable device; otherwise, another screen wake-up instruction generated by user operation, namely a second screen wake-up instruction, is needed to light up the screen of the wearable device, so that the purpose of increasing the power consumption of the wearable device due to repeated screen lightening caused by misoperation of the user is reduced, meanwhile, the occurrence of an event that the sleep quality of the user is possibly reduced due to repeated screen lightening is reduced, and the user experience is improved.

It should be noted that, the current sleep state of the user can be quickly determined to be the non-sleep state and the sleep state through the physiological characteristic data of the user or the motion posture data of the user. The wearable device accurately judges whether the current sleep state of the user is ready to enter the sleep state, and the judgment accuracy of whether the current user operation is misoperation is improved.

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

The user operation related to the embodiment of the application includes, but is not limited to, a click operation, a double-click operation, a continuous click operation, a pressing operation, a multi-pressing operation, a sliding operation, a wrist-turning operation, or a combination operation of at least two of the above user operations, such as a combination operation of pressing and wrist-turning operations.

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

It is understood 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 a wrist-up 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 in a different mode from the normal mode in the anti-false touch mode, for example, the user operation corresponding to the second screen wake-up instruction includes a double-click operation, a continuous-click operation, a multi-press operation, a sliding operation, a combined wrist-lifting and pressing operation, and the like.

The following describes in detail a display control method provided in 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 band, a smart watch, and the like, wakes up the screen by mainly touching or pressing the screen, lifting the wrist, and the like, and although the screen can be quickly woken up, there are certain disadvantages. For example, when the user sleeps at night, the user may easily mistakenly press or touch the screen of the wearable device 100 by himself or a person sitting on the pillow, and especially after the user turns on the wrist-lifting and screen-lighting function of the wearable device 100, the user may even turn over to wake up the screen. During the night sleep, the repeated screen lightening affects the sleep of the user and also increases the power consumption of the wearable device 100. How to improve the discernment rate of accuracy to the screen action of awakening up, avoid bright screen spurious triggering to reduce because of the power consumption of the wearable equipment that bright screen increases repeatedly, and reduce the influence to user's sleep quality is the major technical problem that needs to solve at present.

In the prior art, in order to prevent the user from being disturbed during sleeping at night, a disturbance-free mode is provided on most wearable devices 100. After the user turns on the do-not-disturb mode, incoming call information, notification information such as WeChat notification, QQ notification, etc. do not trigger the vibration of the wearable device 100, and the user does not light up when lifting the wrist. At present, there are two methods for turning on the non-disturbing mode of the wearable device 100: (1) starting at a specified time period; such as a user setting to turn on the do-not-disturb mode for a particular period of time; or the do not disturb mode is turned on until the user turns off. (2) Intelligently starting; upon recognizing that the user is in the sleep state, the wearable device 100 stops receiving the information notification.

However, both of the methods for starting the do-not-disturb mode have disadvantages, for example, for the first method for starting the do-not-disturb mode, on one hand, the specified time period is to start the do-not-disturb mode within the time period set by the user, which is not intelligent enough; on the other hand, after the do-nothing mode is turned on, the interference of the bright screen event caused by accidental touch and mistaken pressing of the user or a sleeper at night cannot be solved only by preventing the interference of external information such as incoming call information, WeChat notification, QQ notification or wrist-lifting bright screen. For the second method for turning on the do-nothing mode, although the do-nothing mode can be turned on intelligently according to the sleep state of the user, on one hand, the turn-on of the do-nothing mode only prevents the interference of external information, and cannot solve the interference of screen-on events caused by accidental touch, mistaken press and the like of the user or a person on the head at night; on the other hand, the non-disturbing mode is turned on when the current sleep state of the user is recognized as the sleep state, but actually, when the current sleep state of the user is a preparation sleep stage, that is, the user is in a state of not sleeping, the user is more easily disturbed by the bright screen of the wearable device 100, and the sleep quality of the user who is difficult to fall asleep 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 caused by repeated screen lightening due to user misoperation, prevent the user sleep from being influenced by the repeated screen lightening caused by the user misoperation, and improve the use experience of the user.

Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a display control method according to an embodiment of the present disclosure. As shown in fig. 2, the method includes steps S101 to S105.

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

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

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.

And S104, if the current sleep state of the user does not meet the preset condition, the wearable device 100 executes a first screen awakening instruction, and lights the screen of the wearable device 100.

The sleep states in the embodiment of the application comprise three states of not entering sleep, entering sleep and preparing to enter sleep. Determining the current sleep state of the user, that is, determining whether the current sleep state of the user is a sleep state that is not entered, a sleep state that has been entered, or a sleep state that is ready to enter, by determining the sleep state of the user, when the current sleep state of the user is a sleep state that is not entered, a first screen wake-up instruction can be directly executed, and a screen of the wearable device 100 is lit; when the current sleep state of the user is the sleep state or is ready to enter the sleep state, the screen of the wearable device 100 needs to be lightened through the second screen wake-up instruction, so that the power consumption of the wearable device 100 is reduced due to repeated screen lightening caused by misoperation of the user in the two sleep states, the phenomenon that the sleep of the user is affected due to the repeated screen lightening caused by the misoperation 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 implementation of the present application, the current sleep state of the user meets the preset condition, specifically, when the current sleep state of the user is the sleep state already entered 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 whose current sleep state is ready to enter the sleep state inadvertently touches any or a designated screen area of the wearable device 100 or lifts his wrist while turning over, the wearable device 100 executes a screen wake-up command generated by these user operations, and especially in the case where the user turns off the wearable device, i.e., the brightness of the environment in which the wearable device is currently located is very dark, the wearable device 100 screen is lighted, and the sudden screen lighting may irritate the eyes of the user in darkness, which may affect the sleep quality of the user while causing eye discomfort. Especially, for a user who is difficult to fall asleep, for example, a user who is difficult to fall asleep due to the influence of light, the sudden or repeated bright screen may seriously affect the sleep quality of the user, so that the user may perceive the bright screen of the wearable device 100, or view or browse the display content of the wearable device 100 after the wearable device 100 is bright screen, which may easily make it more difficult for the user who is difficult to fall asleep to enter a sleep state, and thus the user experience is very poor. Moreover, repeated screen lightening caused by misoperation of the user also increases the power consumption of the wearable device 100, and reduces the 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 the sleep state ready to be entered, the wearable device 100 recognizes the user operation corresponding to the generated screen wake-up instruction as a misoperation, and shields the screen wake-up instruction without lighting up the screen, so that discomfort caused by the user being lighted up due to the user misoperation can be effectively reduced, power consumption of the wearable device 100 due to repeated screen lighting-up is effectively reduced, and the influence of the repeated screen lighting-up on the sleep of the user due to the user misoperation is prevented. At this time, if the user further wants to wake up the screen of the wearable device 100, the screen needs to be lighted up by the screen wake-up instruction (i.e., the second screen wake-up instruction) generated based on another user operation so as to be distinguished from the screen wake-up instruction (i.e., the first screen wake-up instruction) generated by the previous user operation, so that the user can still light up the screen of the wearable device 100 by the screen wake-up instruction generated by another user operation after the wearable device 100 determines that the current sleep state of the user is the sleep state entered or is ready to enter the sleep state, which meets the diversified requirements of the user and improves the user experience.

In other implementations, it may be possible that the user still wants to illuminate the screen of the wearable device 100 to view time or view other content after the wearable device 100 determines that the user's current sleep state is or is ready to enter the sleep state, or after the wearable device 100 turns on the anti-false touch mode. 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 shielded, and the screen of the wearable device 100 is not lighted, the illusion that the user device is damaged or has a problem is possibly given, and the use experience of the user is reduced. In order to avoid this situation, in the embodiment of the present application, after determining that the current sleep state of the user is the sleep state already entered or is ready to enter the sleep state, the wearable device 100 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 is received, and if the second screen wake-up instruction is detected, the wearable device 100 executes the second screen wake-up instruction to light up the screen of the wearable device 100, so that the user can conveniently view the display content of the wearable device 100, thereby satisfying the diversified needs of the user, and improving the user experience.

According to the embodiment of the application, after a first screen awakening instruction is received, the current sleep state of a user is determined; 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, the power consumption of the wearable device 100 caused by repeated screen lightening due to misoperation of the user can be effectively reduced, the standby time of the wearable device 100 is prolonged, adverse effects such as discomfort of eyes and influence on sleep quality of the user caused by repeated screen lightening due to misoperation are reduced, and the user experience is improved.

Referring to fig. 3, fig. 3 is a schematic flowchart illustrating another display control method according to an embodiment of the present disclosure. As shown in fig. 2, the method includes steps S201 to S204.

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

S201 can be described with reference to step S101 in the embodiment described in fig. 2, and is not described herein again.

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

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

In the embodiment of the present application, the current screen states of the wearable device 100 include a screen-on state and a screen-off state. When the screen state of the wearable device 100 is in the bright screen state, the first screen wake-up instruction may be directly executed to light the screen of the wearable device 100, so that the user may browse or view corresponding display content quickly. When the screen state of the wearable device 100 is in the screen-off state, the screen lightening caused by the misoperation of the user corresponding to the first screen awakening instruction needs to be avoided, and the judgment accuracy rate of the repeated screen lightening caused by the misoperation of the user can be improved by determining the current sleep state of the user, so that the power consumption of the wearable device increased by the repeated screen lightening caused by the misoperation of the user is reduced, and the purpose that the sleep of the user is influenced by the repeated screen lightening caused by the misoperation of the user is prevented.

And 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 can be described with reference to step S105 in the embodiment described in fig. 2, and is not described herein again.

Referring to fig. 4, fig. 4 is a schematic flowchart illustrating another display control method according to an embodiment of the present disclosure. As shown in fig. 4, the method includes steps S301 to S304.

S301, the wearable device 100 receives a first screen wake-up instruction. S301 can be described with reference to step S101 in the embodiment described in fig. 2, and is not described herein again.

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

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

In this embodiment of the application, the user may set the false touch prevention mode to be turned on within a specified time period, for example, 22:00 to 7:00 of the next day, after the false touch prevention mode of the wearable device 100 is turned on, and within the specified time period, when the wearable device 100 is in the screen-off state, if the user does not touch any screen area or specified screen area of the wearable device 100, or the user lifts or turns over the wrist, the wearable device 100 will detect a screen wake-up instruction generated based on the current user operation, 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, turn on the screen. Otherwise, the user operation corresponding to the first screen awakening instruction is determined as misoperation, the screen awakening 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 the misoperation of the user.

The preset user operation is an operation preset to wake up the screen in the anti-false touch mode, such as a double click, a continuous click, or an operation of pressing any area or a designated area of the screen multiple times, a sliding operation performed in any area or a designated area of the screen, a combined operation of pressing and raising the wrist, and the like.

S303, if the false touch prevention 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 can be described with reference to step S105 in the embodiment described in fig. 2, and is not described herein again.

According to the embodiment of the application, whether the false touch prevention mode is started or not is determined, so that whether the current stage of the user needs to be determined to trigger the automatic false touch prevention function or not is determined, the intelligent degree of the wearable device is improved, and different requirements of people are met.

Referring to fig. 5, fig. 5 is a schematic flowchart illustrating another display control method according to an embodiment of the present disclosure. 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 to light 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 determines 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 up the screen of the wearable device 100.

In the embodiment of the present application, when the wearable device 100 is in the screen-off state and the user clicks or presses the screen of the wearable device 100 for the first time, the wearable device 100 will detect the first screen wake-up command generated based on this click or pressing operation of the user, at this time, after determining that the current sleep state of the user is the sleep state entered or is ready to enter the sleep state, the wearable device 100 will not execute the first screen wake-up command for a while, and continue to detect whether the user acts on the screen of the wearable device 100 through sliding, double-clicking, etc. for the second time within a predetermined time, that is, the wearable device 100 detects whether the second screen wake-up command generated based on another user operation of the user such as sliding, double-clicking, etc. is received within the predetermined time, if the second screen wake-up command is received within the predetermined time, the wearable device 100 may then execute the first screen wake-up command to illuminate the screen, and may also execute the second screen wake-up command to illuminate the screen. If the second screen awakening instruction is not received within the preset time, the wearable device 100 determines that the user operation corresponding to the first screen awakening instruction is misoperation, shields the first screen awakening instruction, and does not lighten the screen of the wearable device 100.

According to the embodiment of the application, whether the screen of the wearable device 100 is lightened is determined by judging whether the second screen awakening instruction is received or not, so that the occurrence of the event of repeatedly lightening the screen caused by misoperation of the user is reduced, discomfort brought to the user by lightening the screen caused by misoperation of the user can be effectively reduced, and the power consumption of the wearable device 100 increased by repeatedly lightening the screen of the wearable device is effectively reduced.

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

It should be noted that the sleep detection data is related detection data for determining the 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.

The sleep detection data can judge whether the current sleep state of the user is not in the sleep state, is in the sleep state or is ready to enter the sleep state. Further judging whether the user operation corresponding to the first screen instruction needs to be judged as misoperation, if the user operation corresponding to the first screen instruction is not misoperation, the wearable device 100 can execute the first screen wake-up instruction and light the screen of the wearable device 100; otherwise, another screen wake-up instruction, that is, a second screen wake-up instruction, is needed to light up the screen of the wearable device 100, so as to reduce the repeated screen brightening caused by the misoperation of the user and increase the power consumption of the wearable device 100, prevent the repeated screen brightening caused by the misoperation of the user from affecting the sleep of the user, and improve the user experience.

It should be noted that, the current sleep state of the user can be quickly determined to be the non-sleep state and the sleep state through the physiological characteristic data of the user or the motion posture 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 a misoperation, so that the accuracy of determining whether the sleep state of the user is ready to enter the sleep state is improved, the accuracy of determining whether the user operation corresponding to a certain screen wake-up instruction is a misoperation can be effectively improved, and the purpose of preventing the user from being touched by mistake is achieved.

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 present application. As shown in fig. 6, the method includes steps S501 to S503.

The ambient light level of the environment in which the wearable device 100 is currently located can be acquired by the ambient light sensor 180L.

S502, the wearable device 100 determines whether the acquired gesture data of the wrist of the user meets a first condition, and whether the ambient 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, it is determined whether the acquired gesture data of the wrist of the user meets a first condition, specifically, it may be determined whether an average value, a variance, a median, and the like of a root mean square obtained from the gesture data of the wrist of the user within a period of time acquired from the wearable device 100 meets a corresponding preset value range; or judging whether the action level corresponding to the wrist gesture data of the user is a preset action level. And if the mean value, the variance, the median and the like of the root mean square obtained according to the wrist gesture data of the user in a period of time accord with a corresponding preset numerical range, or the action grade corresponding to the wrist gesture data of the user is a preset action grade, determining that the obtained wrist gesture data of the user accord with a first condition.

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

In 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; and if the action grade corresponding to the determined wrist gesture data of the user is a preset action grade, determining that the wrist gesture data of the user meets a first condition.

In some embodiments, the wearable device 100 acquires N acceleration data ACC 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_xn，ACC_yn，ACC_znWherein N is an integer greater than or equal to 1, and N is an integer [1, N ]]Calculating N accelerations ACC of the wearable device 100 in three directions of x, y and z axes_xn，ACC_yn，ACC_znMean, median, variance of root mean squareEquating to obtain a corresponding first numerical value, and determining the action level corresponding to the wrist gesture data of the user according to the value range of dividing the first numerical value into the corresponding action levels.

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

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

Specifically, the table 1 may be referred to as a numerical table corresponding to the action level. Each action level corresponds to a different range of values, e.g., level 0 corresponds to a range of values that is a first mean range, e.g., [ a ]₁,a₂B), a first median range such as [ beta ]₁,β₂) Or a first variance range such as [ gamma ]₁,γ₂) (ii) a The numerical range 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 this embodiment of the application, the corresponding action level is determined according to the wrist gesture data of the user, and the acceleration of the wrist movement of the user can be used, that is, the wearable device 100 can acquire N acceleration data (the acceleration ACC in the three directions of x, y and z axes) of the wearable device 100 in a period of time through the three-axis acceleration sensor_xn，ACC_yn，ACC_zn) Specifically, the motion level corresponding to the wrist gesture data of the user may be determined by calculating a mean and a variance of root mean square of the obtained N pieces of acceleration data, or by obtaining a median of the root mean square of the N pieces of acceleration data.

In some specific embodiments, the wearable device 100, upon receiving the first screen wake-up command, acquires acceleration data at a receiving time point (a time point when the first screen wake-up command is received), and N-1 pieces of acceleration data in 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 are N pieces), calculates a mean value of root-mean-square of the acquired N pieces of acceleration data, obtains a mean value, matches the calculated mean value with a value corresponding to the mean value in a value table corresponding to a motion level, and determines a motion level corresponding to the wrist posture data of the user according to a result of the matching.

In the preset time range, acceleration data of the wearable device 100 in a time period of [08:00:00,08:00:10] is acquired, where the receiving time point is an ending time and the time point before the push is a specific time period is a starting time, for example, the receiving time point is 08:00:00 (eight am), and the time before the push is 10s is 08:00:10 (eight am ten seconds).

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

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

In order to improve the accuracy of judging the action grades corresponding to the wrist gesture data of the user, the embodiment of the application determines at least two corresponding action grades according to the acquired wrist gesture data of the user; comparing the at least two corresponding action grades; if there are at least two motion levels having the same level among the at least two corresponding motion levels, the motion level having the same level and the largest number of motion levels is set as the motion level corresponding to the wrist gesture data of the user.

In some specific embodiments, after determining at least two motion levels of the current wrist of the user according to any two or more of the mean, the variance, or the median in the above embodiments, the determined motion levels are compared, and if at least two motion levels with the same level exist in the at least two corresponding motion levels, the motion level with the same level and the largest number is set as the motion level corresponding to the wrist gesture data of the user, for example, if two motion levels corresponding to the wrist gesture data of the determined user are two, if the two motion levels are consistent, the motion level corresponding to the two consistent motion levels is used as the motion level corresponding to the wrist gesture data of the user; otherwise, the N pieces of acceleration data are acquired again to determine the action level corresponding to the wrist gesture data of the user. If the two action levels corresponding to the determined wrist gesture data of the user are more than two, if the proportion of the action levels with the same number and the largest number in the more than two action levels to the total number of the action levels corresponding to the current wrist gesture data of the user reaches a preset threshold value, setting the action levels with the same number and the largest number as the action levels corresponding to the wrist gesture data of the user, and otherwise, acquiring N pieces of acceleration data again to determine the action levels corresponding to the wrist gesture data of the user. Or further determining the action grade of the user through the movement amplitude of the wrist of the user, comparing the obtained action grades, and determining the action grade corresponding to the wrist gesture data of the user according to the comparison result.

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

In 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 motion level corresponding to the determined wrist gesture data of the user is a preset motion level, such as the above level 0 or level 1, it is determined that the wrist gesture data of the user meets the first condition.

For example, when the action level corresponding to the wrist gesture data of the user is level 0, the current sleep state of the user may be considered as the sleep state entered, and when the action level corresponding to the wrist gesture data of the user is level 1, the current sleep state of the user may be considered as the sleep state ready to enter. When the action level corresponding to the wrist gesture data of the user is 2 levels or more, the current sleep state of the user can be considered as a sleep state.

When the ambient light brightness of the current environment of the wearable device 100 is not lower than the preset brightness threshold, even if the screen of the wearable device 100 is turned on, the discomfort of the eyes of the user is not caused, but the power consumption of the wearable device 100 is increased, therefore, when the ambient light brightness of the current environment of the wearable device is not lower than the preset brightness threshold, but when the gesture data of the wrist of the user meets 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 lightening caused by misoperation of the user is reduced, 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 parameters such as heart rate, respiration, etc. For example, by determining whether the heart rate of the user is lower than a preset heart rate value, whether the number of breaths within a preset time is lower than a preset number, and the like.

It is understood that, when the current sleep state of the user is the sleep state entered state, in order to reduce the power consumption of the wearable device 100 caused by the repeated screen-on due to the user misoperation, the first screen wake-up command is generally directly masked after the current sleep state of the user is the sleep state entered state. If the user wakes up suddenly and wants to light the screen, the screen needs to be lighted through the second screen wake-up instruction, so that the wearable device can distinguish the screen wake-up operations 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 meets the preset condition is determined by judging whether the acquired gesture data of the wrist of the user meets the first condition and whether the ambient light brightness of the current environment of the wearable device 100 is lower than the preset brightness threshold, namely whether the current sleep state of the user is in the sleep state or is ready to enter the sleep state is determined, so that the accuracy of judging whether the user operation corresponding to a certain screen awakening instruction is misoperation can be effectively improved, and the purpose of preventing the user from being touched mistakenly is achieved.

It should be noted that, due to the limitation of the wearable device 100 itself, 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 a suspected sleep stage or a sleep stage, that is, after the wearable device 100 detects the first screen wake-up instruction, the wearable device 100 may send a sleep stage confirmation request instruction to a third-party electronic device, for example, a smartphone bound to the wearable device 100, where the sleep stage confirmation request instruction is used to instruct the third-party electronic device to judge the current sleep state of the user, and the third-party electronic device feeds back the judgment result to the wearable device 100, that is, the execution main body of the steps S501 to S503 may be other electronic devices except the wearable device 100.
