Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to fig. 1 to 10 in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

The embodiment of the application provides a wearable device 100, and the wearable device 100 may be, but is not limited to, an electronic device such as a smart bracelet, a smart watch, a wireless earphone, and the like. The wearable device 100 of the embodiment of the present application is illustrated by taking a smart watch as an example. Referring to fig. 1 to 3, fig. 1 is a first structural schematic diagram of a wearable device 100 provided in an embodiment of the present application, fig. 2 is a structural schematic diagram of another view angle of the wearable device 100 provided in an embodiment of the present application, and fig. 3 is a second structural schematic diagram of the wearable device 100 provided in an embodiment of the present application. The wearable device 100 includes a device body 110, a first detection module 120, a second detection module 130, and a processor 140.

The device body 110 includes a first region 111 and a second region 112, the first region 111 is a region spaced apart from a user when the wearable device 100 is in a wearing state, and the second region 112 is a region in contact with the user when the wearable device 100 is in a wearing state. The first detection module 120 is disposed in the first area 111, and the first detection module 120 can detect first ambient light information of the wearable device 100. The second detection module 130 is disposed in the second area 112, and the second detection module 130 can transmit an optical signal and detect the first wearing information of the wearable device 100 according to the optical signal. The processor 140 is directly or indirectly electrically connected to the first detection module 120 and the second detection module 130, respectively, and the processor 140 may adjust a first threshold range corresponding to the first wearing information according to the first ambient light information, and may determine that the wearable device 100 is in a wearing state when the first wearing information conforms to the first threshold range.

The apparatus body 110 may include a main body 113, a first wearing part 114, and a second wearing part 115, and the first wearing part 114 and the second wearing part 115 may be directly or indirectly connected to both ends of the main body 113, respectively. The first wearing part 114 and the second wearing part 115 may fix the wearable device 100 to the user's body such that the wearable device 100 is in a worn state. The first region 111, the second region 112 may be, but are not limited to, regions on the main body 113, the first wearing part 114, and the second wearing part 115. For example, the first region 111 may be a region on the front or side of the main body 113, the first wearing part 114, the second wearing part 115; the second region 112 may be a region on the back surface of the main body 113, the first wearing part 114, and the second wearing part 115. The back surface refers to a surface of the wearable device, which is in contact with the skin of a user in a wearing state, the front surface is a surface opposite to the back surface, and the side surface is at least one surface connected between the front surface and the back surface.

It will be appreciated that the body 113 may form the primary structure of the wearable device 100 and may house portions of the electronics of the wearable device 100. When wearable device 100 is a smart watch, body 113 may be a dial of wearable device 100. Wherein, the main body 113 may be a cuboid, and the wearable device 100 is a square dial; the body 113 may also be a cylinder, and the wearable device 100 is a dial; the body 113 may also be an irregular polyhedron, and the wearable device 100 is an irregular dial. The specific shape of the main body 113 is not limited in the embodiment of the present application.

It is to be appreciated that the first wearing portion 114 and the second wearing portion 115 may be, but are not limited to, securing the main body 113 to a wrist, ankle, neck, etc. of a user. When the wearable device 100 is a smart watch, the first wearing part 114 and the second wearing part 115 may be watchband structures of the wearable device 100. The first wearing part 114 and the second wearing part 115 may be rotatably connected with both ends of the main body 113 through a rotation shaft, and the first wearing part 114 and the second wearing part 115 may be fixedly connected with both ends of the main body 113 through an integral molding. The first wearing part 114 and the second wearing part 115 may be made of metal or nonmetal such as plastic or nylon. The materials of the first wearing part 114 and the second wearing part 115 may be set according to actual needs, and the embodiment of the present application is not limited thereto.

The first detection module 120 may be a detection device that transmits an optical signal and may detect an ambient light parameter, for example, the first detection module 120 may be a light sensor (e.g., an ambient light sensor). When the first detection module 120 is disposed in the first area 111, the first detection module 120 may detect first ambient light information near the first area 111 of the wearable device 100, which may include, but is not limited to, one or more of ambient light intensity, ambient light flux, ambient illuminance, ambient light color temperature. The first ambient light information may indicate ambient light information in the vicinity of the first area 111.

It is understood that the first detection module 120 may be directly or indirectly connected to the first region 111, or the first detection module 120 may be directly formed on the first region 111. Since the first area 111 is an area where the wearable device 100 is spaced from (does not contact with) the user in the wearing state, the first area 111 is not blocked by the user, the first ambient light information detected by the first detection module 120 is not affected by the user, the first ambient light information may be a parameter of ambient light in the current state of the wearable device 100, and the first ambient light information may be different according to different current environments of the wearable device 100. For example, when the external environment is a sunny day, the intensity of the ambient light detected by the first ambient light information is large; when the external environment is cloudy, the ambient light intensity of the first ambient light information detection is smaller.

It can be appreciated that the first ambient light information may be information related to visible light or information related to invisible light; accordingly, the first detection module may transmit visible light to detect the first ambient light information, and the first detection module may also transmit non-visible light (e.g., without limitation, infrared light) to detect the first ambient light information. This is not limiting in the embodiments of the present application.

The second detection module 130 may be a detection device that transmits an optical signal and may detect the first wearing information of the wearable device 100 according to the optical signal. For example, the second detection module 130 may be, but is not limited to, one or more of a photo sensor, a photo volume pulse wave detector.

It is understood that the second detecting module 130 may be directly or indirectly connected to the second region 112, or the second detecting module 130 may be directly formed in the second region 112. Since the second area 112 is an area where the wearable device 100 contacts the user in the wearing state, when the second detection module 130 is disposed in the second area 112, the second detection module 130 may detect the first wearing information near the second area 112 of the wearable device 100, and the first wearing information may indicate the current relationship between the wearable device 100 and the user. For example, the first wearing information may be an ambient light parameter of the second area 112 detected by the second detection module 130, and the first wearing information may also be biometric information of the user contacting the second area 112 detected by the second detection module 130. This is not particularly limited in the embodiments of the present application.

The processor 140 may be a control center of the wearable device 100, and the processor 140 may be directly or indirectly electrically connected to various parts of the whole wearable device 100 by using various interfaces and lines, and may perform various functions and process data of the wearable device 100 by running or executing corresponding application programs and application data, so as to monitor the wearable device 100 as a whole. The first detection module 120 may transmit the detected first ambient light information, and the second detection module 130 may transmit the detected first wearing information directly or indirectly to the processor 140, so that the processor 140 may perform subsequent operations.

It is understood that in the initial state, the wearable device 100 may be empirically or experimentally preset and store an initial first threshold range corresponding to the first wearing information. Subsequently, the processor 140 may dynamically adjust the first threshold range according to the first ambient light information detected by the first detection module 120, so that the adjusted first threshold range may be more suitable for the current environment. For example, if the current environment is sunny such that the first ambient light information is in the first range, the processor 140 may adjust the first threshold range down/up based on the initial first threshold range; if the current environment is cloudy, such that the first ambient light information is in the second range, the processor 140 may increase/decrease the first threshold range based on the initial first threshold range; the processor 140 may not change the size of the first threshold range if the current environment is cloudy weather such that the first ambient light information is in the third range.

It should be noted that, the manner in which the processor 140 dynamically adjusts the first threshold range according to the first ambient light information detected by the first detection module 120 is not limited to the above example, for example, the wearable device 100 may pre-store a mapping table of the first ambient light information and the first threshold range, and the processor 140 may dynamically adjust the first threshold range according to the mapping table; for another example, the wearable device 100 may determine initial first ambient light information corresponding to the initial first threshold range, and then, the processor 140 may dynamically adjust the first threshold range accordingly according to the first correspondence between the actual first ambient light information detected by the first detection module 120 and the initial first ambient light information, so that the second correspondence between the adjusted first threshold range and the initial first threshold range is adapted to the first correspondence. It is understood that the first correspondence relationship and the second correspondence relationship may be, but are not limited to, a positive correlation relationship, a negative correlation relationship, an equal ratio relationship, a square ratio relationship, an equal difference relationship. The embodiment of the application does not limit a specific manner of dynamically adjusting the first threshold.

It may be appreciated that the processor 140 may determine the current state of the wearable device 100 according to the relationship between the first wearing information detected by the second detection module 130 and the dynamically adjusted first threshold range, so that the determination of the current state of the wearable device 100 may be more suitable for the current environment. For example, when the first wear information meets the first threshold range, the processor 140 may consider the wearable device 100 to be in a worn state; when the first wear information does not meet the first threshold range, the processor 140 may consider the wearable device 100 to be in a disengaged state. The wearing state may refer to a state in which the wearable device 100 is connected to the user, and at this time, the second region 112 of the device body 110 may be in contact with the skin of the user, and the first region 111 may not be in contact with the skin of the user. The detached state may refer to a state in which the wearable device 100 is not connected to the user or the connection is not in compliance with the standard, at which time the second region 112 of the device body 110 is not in contact with the user and the first region 111 may or may not be in contact with the user.

It should be noted that, the threshold range of the detection module for detecting the wearing state in the wearable device 100 in the related art is often a fixed range, and when the wearable device 100 determines the wearing state of the wearable device 100 according to the parameter detected by the detection module and the threshold range, accidental failure occurs, so that the determination of the wearing state is inaccurate. For example, when the external environment is darker, even if the wearable device 100 is in a disengaged state, the detection module determines the wearable device 100 as a wearing state when judging according to the fixed threshold range; for another example, when the external environment is bright, even if the wearable device 100 is in the wearing state, the detection module determines the wearable device 100 as the detached state when judging according to the fixed threshold range. Thus, the determination of the current state of the wearable device 100 of the related art is inaccurate.

In the wearable device 100 of the embodiment of the present application, the first detection module 120 is disposed in a first area 111 spaced from the user in the wearing state of the wearable device 100, and the first ambient light information detected by the first detection module 120 may indicate an ambient light parameter in the current environment of the wearable device 100; the second detection module 130 is disposed in a second area 112 that contacts the user in the wearing state of the wearable device 100, and the first wearing information detected by the second detection module 130 may indicate the current relationship between the wearable device 100 and the user. The processor 140 dynamically adjusts the size of a first threshold range corresponding to the first wearing information according to the first ambient light information, and the first threshold range can be adapted to the current environment; the processor 140 determines the current state of the wearable device 100 according to the first wearing information and the adjusted first threshold range, the current state of the wearable device 100 can be adapted to the current environment of the wearable device 100, and in any scene, the situation that the wearing state detection is accidentally invalid due to the change of the environment cannot occur.

When the processor 140 determines that the wearable device 100 is in the wearing state or the disengaging state, the processor 140 may control the wearable device 100 to execute the corresponding working mode according to the wearing state or the disengaging state. For example, when the wearable device 100 is in the worn state, the processor 140 may control the wearable device 100 to enter a normal operating mode; when the wearable device 100 is in the disengaged state, the processor 140 may control the wearable device 100 to enter a low power consumption mode of operation.

It may be appreciated that the normal operation mode may be that the wearable device 100 executes its standard power consumption mode, and may implement functions such as video, audio playing, navigation, shooting, etc. through software support and data interaction and cloud interaction. For example, when the wearable device 100 is a smart headset, its normal operation mode is a play audio mode; when the wearable device 100 is a pair of smart glasses or a pair of smart helmets, the normal operation mode thereof may be a mode of performing smart display, taking a photograph, playing a video, navigating a map, and the like; when the wearable device 100 is a smart watch, its normal operation mode may be modes such as time display, mobile payment, video chat, real-time positioning, real-time step counting, physiological feature monitoring, etc.

It is understood that the low power consumption mode may refer to that the power consumption of the wearable device 100 is smaller than the standard power consumption, i.e. lower than the normal power consumption. That is, the power consumption when the wearable device 100 operates in the low power consumption mode is smaller than the power consumption when the wearable device 100 operates in the normal operation mode. For example, when the wearable device 100 is in the low power mode, the device body 110 may not perform one or more functions of video, audio playback, navigation, photography, video chat, real-time positioning, real-time step counting, physiological characteristic monitoring, and the like.

The wearable device 100 of the embodiment of the present application may perform a normal operation mode or a low power consumption mode according to the current state of the wearable device 100, and the wearable device 100 does not need to be in the normal operation mode with high power consumption all the time, so that the power consumption of the wearable device 100 is lower.

With reference again to fig. 1 and 3, the wearable device 100 may further include a display 150.

The display screen 150 may be mounted on the main body 113 of the device body 110, and the display screen 150 may form a display surface of the wearable device 100, for displaying information such as images and texts on the wearable device 100, or for displaying images and texts and for performing man-machine interaction on a user, for example, the user may perform touch operation on the wearable device 100 through the display screen 150. The display 150 may be a liquid crystal display (Liquid Crystal Display, LCD) or an Organic Light-Emitting Diode (OLED).

It is understood that the display 150 may include a display area and a non-display area. The display area performs a display function of the display screen 150, and is used for displaying information such as images and texts by the wearable device 100, and the non-display area does not display information, and is used for setting functional components such as a camera and a touch electrode of the display screen 150. The display screen 150 may also be a full screen, in which case the display screen 150 may display information full screen so that the wearable device 100 has a larger screen duty cycle. The display 150 includes only a display area and does not include a non-display area, or the area of the non-display area is small for the user. At this time, functional components of the camera, proximity sensor, etc. in the wearable device 100 may be hidden under the display screen 150.

Referring again to fig. 3, the wearable device 100 may further include a memory 160.

Memory 160 may be used to store applications and data. The memory 160 stores application programs including executable codes. Applications may constitute various functional modules. The processor 140 executes various functional applications and data processing by running application programs stored in the memory 160. It will be appreciated that the specific structure of the memory 160 may be referred to in the description of the related art, and will not be described in detail herein.

It should be noted that, the wearable device 100 may include, but is not limited to, one or more of a power module, a radio frequency module, a camera module, and a sensor module, in addition to the above-described structure. The specific structure of the wearable device 100 is not limited in the embodiments of the present application.

Referring to fig. 2 again, the second detection module 130 may include a light detection module 131.

The light detection module 131 may transmit a light signal and may detect second ambient light information of the wearable device 100 according to the light signal, at which time the first wearing information detected by the second detection module 130 may include the second ambient light information, and the first threshold range corresponding to the first wearing information may include an ambient light threshold range, which may correspond to the second ambient light information. The light detection module 131 may include one or more light sensing sensors (e.g., ambient light sensors). The light detection module 131 may detect second ambient light information in the vicinity of the second region 112 of the wearable device 100, which may include, but is not limited to, one or more of ambient light intensity, ambient light flux, ambient illuminance, ambient light color temperature. The second ambient light information may indicate ambient light information in the vicinity of the second area 112.

When the wearable device 100 is normally worn on the user, the second area 112 of the wearable device 100 is often blocked by the user, and the second ambient light intensity detected by the light detection module 131 is smaller, so that the wearable device 100 may preset an ambient light threshold range corresponding to the second ambient light information according to a smaller ambient light intensity.

It is understood that the processor 140 may dynamically adjust the ambient light threshold range according to the first ambient light information detected by the first detection module 120, so that the ambient light threshold range may be adapted to the current environment. For example, when the first ambient light information shows that the current environment is in a state of strong illumination (sunny state), the processor 140 may dynamically adjust the ambient light threshold range to be smaller, so that the processor 140 does not misjudge the wearing state as the off state; for another example, when the first ambient light information shows that the current environment is in a state of low illumination (rainy day state), the processor 140 may dynamically adjust the ambient light threshold range to be large so that the processor 140 does not confirm the detached state as the worn state.

The method of dynamically adjusting the ambient light threshold range according to the first ambient light information is not limited to the above example, but may be, but not limited to, dynamically adjusting the ambient light threshold range according to the mapping relation table, positive correlation relation, negative correlation relation, geometric relation, square relation, geometric relation, etc. in the foregoing embodiments. This is not limiting in the embodiments of the present application.

When the ambient light threshold is adjusted, the processor 140 may determine that the wearable device 100 is in the worn state when the second ambient light information meets the ambient light threshold range. The processor 140 may determine that the wearable device 100 is in the disengaged state when the second ambient light information does not meet the light threshold range.

It is understood that the processor 140 may also determine the disengagement state of the wearable device 100 in other ways, which is not limited by the embodiments of the present application.

According to the wearable device 100, the first detection module 120 can detect the first ambient light information of the first area 111, the second detection module 130 can detect the second ambient light information of the second area 112, and the first detection module 120 and the second detection module 130 can both detect the ambient light information, so that after the processor 140 adjusts the ambient light threshold range corresponding to the second ambient light information according to the first ambient light information, the ambient light threshold range can be more suitable for the current environment, and the judgment result of the current state of the wearable device 100 is more accurate.

Referring again to fig. 2, the light detection module 131 may include a first light detector 1311 and a second light detector 1312.

The first light detector 1311 and the second light detector 1312 may be light-sensitive sensors. The second region 112 of the device body 110 may include a first sub-region 1121 and a second sub-region 1122, the first sub-region 1121 and the second sub-region 1122 may be disposed at intervals, a first detector may be disposed at the first sub-region 1121, a second light detector 1312 may be disposed at the second sub-region 1122, and the first light detector 1311 and the second light detector 1312 may collectively detect second ambient light information of the second region 112.

It is understood that the first sub-region 1121 may be formed on the first wearing portion 114, for example, formed on the back surface of the first wearing portion 114; the second subregion 1122 may be formed on the second wearing part 115, for example, on the back surface of the second wearing part 115. The first and second subregions 1121, 1122 may be in close proximity to the user when the wearable device 100 is in the worn state. Of course, the first and second sub-regions 1121, 1122 may be formed in other regions of the wearable device 100, for example, the first and second sub-regions 1121, 1122 may be disposed at intervals in the main body 113. This is not particularly limited in the embodiments of the present application.

It is appreciated that the first sub-region 1121 and the second sub-region 1122 may be symmetrically disposed about the central axis L0 of the device body 110 such that the first light detector 1311 and the second light detector 1312 may be symmetrically disposed, at which time the first light detector 1311 and the second light detector 1312 may better detect the second ambient light information of the wearable device 100. Of course, the first sub-region 1121 and the second sub-region 1122 may be disposed asymmetrically, which is not limited in the embodiment of the present application.

It is understood that the first light detector 1311 and the second light detector 1312 may be the same type of light sensor or different types of light sensor. The embodiment of the present application is not particularly limited as such.

The first light detector 1311 may detect first sub-ambient light information of the first sub-region 1121 and the second light detector 1312 may detect second sub-ambient light information of the second sub-region 1122. The processor 140 may adjust a first sub-threshold range corresponding to the first sub-ambient light information detected by the first light detector 1311 according to the first ambient light information, or may adjust a second sub-threshold range corresponding to the second sub-ambient light information detected by the second light detector 1312 according to the first ambient light information. Meanwhile, the processor 140 may further determine the current state of the wearable device 100 according to the first sub-ambient light information, the first sub-threshold range, the second sub-ambient light information, and the second sub-threshold range.

For example, the processor 140 may determine that the wearable device 100 is in the worn state when the first sub-ambient light information meets the first sub-threshold range and the second sub-ambient light information meets the second sub-threshold range; the processor 140 may also determine that the wearable device 100 is in the disengaged state when the first sub-ambient light information does not meet the first sub-threshold range and/or the second sub-ambient light information does not meet the second sub-threshold range.

Of course, the manner of determining the current state of the wearable device 100 according to the first sub-ambient light information, the first sub-threshold range, the second sub-ambient light information, and the second sub-threshold range is not limited to the above example, and may be determined according to a difference between the first sub-ambient light information and the first sub-threshold range and a difference between the second sub-ambient light information and the second sub-threshold range, for example. This is not particularly limited in the embodiments of the present application.

According to the wearable device 100 of the embodiment of the application, the first light detector 1311 and the second light detector 1312 are symmetrically arranged, the processor 140 determines the current state of the wearable device 100 according to the ambient light information detected by the first light detector 1311 and the second light detector 1312 and the threshold range thereof, and accidental errors caused by single-point detection due to hand movement of a user can be avoided, so that the state determination result of the wearable device 100 of the embodiment of the application is more accurate.

It should be noted that, in other embodiments, the light detection module 131 of the present application may further include at least one additional light detector other than the first light detector 1311 and the second light detector 1312, where the plurality of light detectors are distributed in different areas at intervals and jointly detect the second ambient light information of the second area 112, and at this time, the wearable device 100 may also avoid accidental errors caused by single-point detection, so that the state determination result of the wearable device 100 is more accurate.

Referring again to fig. 2, in some embodiments, the wearable device 100 or the second detection module 130 may further include a biometric detection module 132.

The threshold range in which the biometric detection module 132 may detect that the biometric information of the user of the second region 112 corresponds to the biometric information may include a biometric threshold range. When the second detection module 130 further includes the biometric detection module 132, at this time, the first wearing information detected by the second detection module 130 may further include the biometric information, and the first threshold range corresponding to the first wearing information may further include the biometric threshold range.

It is understood that the biometric detection module 132 may be, but is not limited to being, one or more of a photoplethysmograph detector, an optical heart rate detector, a temperature sensor, an electrocardiograph (ECG electrode) sensor, a bioimpedance sensor; the biometric information may include, but is not limited to, one or more of the parameter information including blood pulse rate, heart rate, blood volume, blood oxygen, respiration rate, oxygen intake, blood pressure, etc.

It may be appreciated that the biometric detection module 132 may be disposed in the second area 112, and the biometric detection module 132 may determine whether the object in contact with the second area 112 is a living body according to the detected biometric information, and if so, may primarily determine that the wearable device 100 is in contact with the user; if not, it may be initially determined that wearable device 100 is not in contact with the user.

It is understood that the second detection module 130 may include both a light detection module 131 and a biological feature detection module 132, and the light detection module 131 and the biological feature detection module 132 may be disposed in different regions of the second region 112. For example, the second region 112 may further include a third sub-region 1123, and the biometric detection module 132 may be disposed at the third sub-region 1123, and the third sub-region 1123 may be, but is not limited to, a region of the back of the body 113. The processor 140 may comprehensively determine the current state of the wearable device 100 according to the relationship of the second ambient light information and the ambient light threshold range and the relationship of the biometric information and the biometric threshold range.

For example, processor 140 may determine that wearable device 100 is in a worn state when the second ambient light information meets the ambient light threshold range and the biometric information meets the biometric threshold range; the processor 140 may also determine that the wearable device 100 is in the disengaged state when the second ambient light information does not meet the ambient light threshold range and/or the biometric information does not meet the biometric threshold range. Of course, the processor 140 may also determine the detachment status of the wearable device 100 in other manners, which is not limited by the embodiments of the present application.

It may be appreciated that the processor 140 may adjust an ambient light threshold range of the second ambient light information according to the first ambient light information, and preliminarily determine the current state of the wearable device 100 according to the relationship between the second ambient light information and the ambient light threshold range; and then finally determining the current state of the wearable device 100 according to the relation between the biological characteristic information and the biological characteristic threshold range. Of course, the order of the above steps of the processor 140 may be arbitrarily adjusted. This is not limiting in the embodiments of the present application.

The wearable device 100 of the present embodiment, the second detection module 130 includes a light detection module 131 and a biological feature detection module 132, and the processor 140 may determine the current state of the wearable device 100 according to the second ambient light information detected by the light detection module 131 and the biological feature information detected by the biological feature detection module 132, so that the determination of the current state of the wearable device 100 is more accurate.

Wherein, when the biometric detection module 132 transmits the optical signal and determines the biometric information of the user through the optical signal, the processor 140 may further adjust a corresponding biometric threshold range of the biometric information according to the first environmental light information so that the biometric threshold range may be adapted to the current environment.

The wearable device 100 may preset a biological feature threshold range according to experience or experiment, and then the processor 140 may dynamically adjust the biological feature threshold range according to the first ambient light information detected by the first detection module 120 and in a mapping relationship table, a positive correlation relationship, a negative correlation relationship, an equal ratio relationship, a square ratio relationship, an arithmetic relationship, and the like. The specific adjustment manner is not limited herein in this embodiment.

Upon adjusting the biometric threshold range, the processor 140 may determine that the wearable device 100 is in a worn state when the biometric information meets the biometric threshold range. The processor 140 may also determine that the wearable device 100 is in the disengaged state when the biometric information does not meet the biometric threshold range. Of course, the processor 140 may also determine the detachment status of the wearable device 100 in other manners, which is not limited by the embodiments of the present application.

In the wearable device 100 of the embodiment of the present application, the biological feature detection module 132 may transmit an optical signal and detect biological feature information of the second area 112 according to the optical signal, on one hand, whether the user wears the wearable device 100 may be accurately determined according to the biological parameter detected by the biological feature detection module 132; on the other hand, after the processor 140 adjusts the biometric threshold range according to the first ambient light information, the biometric threshold range can be more adaptive to the current environment, and according to the adjusted biometric threshold range and the biometric information, the current state of the wearable device 100 can be more accurately determined.

It should be noted that, in the embodiment of the present application, the second detection module 130 may include the light detection module 131 and the biological feature detection module 132, and the second detection module 130 may also include the light detection module 131 alone. Of course, when the biometric detection module 132 may transmit an optical signal and may detect biometric information of the wearable device 100 according to the optical signal, the second detection module 130 may also include the biometric detection module 132 alone, and at this time, the processor 140 may adjust a biometric threshold range corresponding to the biometric information according to the first ambient light information and may determine whether the wearable device 100 is in a wearing state when the biometric information conforms to the biometric threshold range. The specific operation of the biometric detection module 132 and the processor 140 can be referred to the description of the foregoing embodiments, and will not be described herein.

Referring again to fig. 2, the biometric detection module 132 may be a photoplethysmography detector.

The photoplethysmography detector may include one or more light emitters 1321 and a plurality of light receivers 1322, where the light emitters 1321 may be spaced apart from each other, the light receivers 1322 may be spaced apart from each other, and the light emitters 1321 and the light receivers 1322 may be spaced apart from each other. For example, the plurality of light receivers 1322 may be evenly and intermittently wrapped around the one or more light emitters 1321.

The light emitter 1321 may emit a light signal to a direction in which a user is located, where the light signal is reflected through skin tissue after encountering skin of the user to form a reflected light signal, and the reflected light signal is received by the light receiver 1322 and converted into an electrical signal, and since absorption of light by tissues such as muscle, bone, vein, etc. of a human body is substantially unchanged, but the flow of blood may absorb a part of the light signal, the characteristic of blood flow may be reflected by analyzing a direct current DC signal and an alternating current AC signal in the electrical signal formed by the reflected light signal, and extracting the alternating current AC signal. And thus may determine whether the wearable device 100 is worn by the user.

It is understood that the light emitter 1321 may be a light emitting diode structure and the light receiver 1322 may be a photodiode structure. When the photoplethysmograph detector includes a plurality of light emitters 1321, the plurality of light emitters 1321 may emit light of the same color or at least two different colors, each light receiver 1322 may receive light of one color, and the light receivers 1322 receiving the same color are disposed at intervals, so that a light channeling phenomenon caused by light of different colors may be prevented.

It will be appreciated that, since the photoplethysmography detector needs to emit an optical signal and detect the biometric information of the user according to the optical signal, the processor 140 may dynamically adjust the biometric threshold range corresponding to the biometric information detected by the photoplethysmography detector according to the first ambient light information, where the biometric information may be at least one of pulse wave information, blood oxygen information, heart rate information, blood pressure information, etc., and the corresponding biometric threshold range may be at least one of pulse wave threshold range, blood oxygen threshold range, heart rate threshold range, blood pressure threshold, etc.

For example, if the current environment is a sunny day such that the first ambient light information is in the first range, the processor 140 may adjust the biometric threshold range to be smaller than the initial biometric threshold range; if the current environment is cloudy such that the first ambient light information is in the second range, the processor 140 may increase the biometric threshold range based on the initial biometric threshold; the processor 140 may not change the size of the biometric threshold range if the current environment is cloudy weather such that the first ambient light information is in the third range.

It should be noted that, in addition to the above embodiment, the processor 140 may dynamically adjust the biometric threshold range according to the first ambient light information detected by the first detection module 120 and by using a mapping relationship table, a positive correlation relationship, a negative correlation relationship, an equal ratio relationship, a square ratio relationship, an arithmetic relationship, or the like. The embodiments of the present application are not limited herein.

The biological feature detection module 132 in the embodiment of the present application is a photoplethysmogram detector, on one hand, the photoplethysmogram detector can detect biological information such as blood oxygen of a user, so as to monitor physiological features of the user; on the other hand, the photoplethysmograph detector is also beneficial to detecting the wearing state of the wearable device 100, so that the wearing state detection result is more stable; therefore, the photoelectric volume pulse wave detector in the embodiment of the application realizes multiplexing, so that the production cost of the wearable device 100 can be saved, and the miniaturized design of the wearable device 100 can be realized.

Referring to fig. 4 and fig. 5, fig. 4 is a third structural schematic diagram of the wearable device 100 provided in the embodiment of the present application, and fig. 5 is a fourth structural schematic diagram of the wearable device 100 provided in the embodiment of the present application. The wearable device 100 of the embodiment of the present application may further include a third detection module 170.

The third detection module 170 may be disposed on the apparatus body 110, for example, on the main body 113, the first wearing part 114, and the second wearing part 115. When the wearable device 100 is normally worn by a user, the third detection module 170 may be in contact with the user or may be separated from the user, and a specific setting position of the third detection module 170 may be adapted to a function of the third detection module. The third detection module 170 may detect second wearing information of the wearable device 100, and an initial second threshold range corresponding to the second wearing information may be determined in advance according to experience or experiment inside the wearable device 100.

It is understood that the second wearing information may be, but is not limited to, one or more of temperature information, pressure information, blood pulse rate information, heart rate information, blood volume information, blood oxygen information, respiration rate information, oxygen intake information, blood pressure information, bioimpedance information, and the like of the user. Accordingly, the third detection module 170 may be, but is not limited to, one or more of a temperature sensor, a pressure sensor, a photoplethysmography detector, an optical heart rate detector, a temperature sensor, an Electrocardiograph (ECG) detector, a bioimpedance detector. For example, as shown in fig. 4, when the third detection module 170 is an electrocardiograph or a bio-impedance detector, a plurality of ECG electrodes or a plurality of bio-impedance measurement electrodes corresponding to the electrocardiograph or the bio-impedance detector may be wound around the periphery of the capacitive pulse wave detector at intervals. It is understood that the specific manner in which the third detecting module 170 detects the second wearing information may vary with the type of the third detecting module 170, for example, the temperature sensor may detect by a principle that the resistance value of the thermistor varies with temperature, or may detect by using the thermoelectric effect of the infrared thermopile; for another example, the pressure sensor may detect by the principle that piezo-resistive or piezoelectric materials produce electrical signals of different magnitudes under different forces. The specific operation mode of the third detection module 170 is not limited in this embodiment.

The third detection module 170 may be directly or indirectly electrically connected to the processor 140, and the processor 140 may further determine whether the wearable device 100 is in a wearing state according to the first wearing information and the second wearing information. For example, the processor 140 may determine that the wearable device 100 is in the worn state when the first wear information meets the first threshold range and the second wear information meets the second threshold range. The processor 140 may also determine that the wearable device 100 is in the disengaged state when the first wear information does not meet the first threshold range and/or the second wear information does not meet the second threshold range. Of course, the manner in which the processor 140 determines that the wearable device 100 is in the disengaged state is not limited thereto, which is not limited in the embodiments of the present application.

According to the wearable device 100, after the processor 140 judges that the wearable device 100 is in the wearing state preliminarily according to the first detection module 120 and the second detection module 130, the wearable device 100 can be further judged according to the second wearing information of the third detection module 170, so that the wearable device 100 jointly determines the current state of the wearable device 100 according to the first detection module 120, the second detection module 130 and the third detection module 170, and judgment errors caused by accidental failure can be avoided, and the judgment of the current state of the wearable device 100 is more accurate.

Referring to fig. 6, fig. 6 is a schematic diagram of a fifth structure of a wearable device 100 according to an embodiment of the present application. The wearable device 100 may also include a counter 180.

The counter 180 may be directly or indirectly electrically connected to the processor 140. The processor 140 may control the first detection module 120, the second detection module 130 (and the third detection module 170) to detect at a preset first time interval, so that the processor 140 may determine the current state of the wearable device 100 multiple times. It is understood that the predetermined first time interval may be an equal time interval, and the first detection module 120, the second detection module 130 (and the third detection module 170) may periodically determine the current state of the wearable device 100 multiple times. Of course, the preset first time interval may be an unequal time interval. The preset first time interval is not specifically limited in the embodiment of the present application.

The processor 140 may input different pulse signals to the counter 180 according to the relationship between the first wearing information detected by the second detection module 130 and the first threshold range. For example, the processor may transmit a high level pulse signal to the counter when the first wear information meets the first threshold range; the processor may transmit a low level pulse signal to the counter when the first wear information does not meet the first threshold range. The counter 180 may count the number of different pulses input, so that the counter 180 may record the number of times the first wearing information meets the first threshold range, and the counter 180 may also record the number of times the first wearing information does not meet the first threshold range.

It will be appreciated that the counter 180 may include a basic counting unit and a number of control gates, and that the counting unit may include various types of flip-flops having information storage functions. Note that, the specific structure of the counter 180 may be referred to the description of the related art, and will not be described here.

The counter 180 may continuously record a first number of times that the first wear information meets the first threshold range. The processor 140 may further ultimately consider the wearable device 100 to be in a wearing state when the first number meets the first number threshold, and may control the wearable device 100 according to the wearing state, for example, the processor 140 may control the wearable device 100 to perform a normal operation mode. The processor 140 may also consider the wearable device 100 to be in a disengaged state when the first number does not meet the first number threshold, and control the wearable device 100 according to the disengaged state, for example, the processor 140 may control the wearable device 100 to perform a low power consumption operation mode.

It will be appreciated that if the counter 180 receives the pulse signal transmitted by the processor 140 in the first range of the threshold value at all times and the first number does not meet the first number threshold value, at this time, if the counter 180 receives the pulse signal transmitted by the processor 140 in the first range of the threshold value, the counter 180 may zero the first number recorded before and may start recording the disengaged state once. Similarly, if the counter 180 receives the pulse signal transmitted by the processor 140 and the number of times of the pulse signal does not meet the first threshold range, and the number of times of the pulse signal does not meet the corresponding number of times threshold, at this time, if the counter 180 receives the pulse signal transmitted by the processor 140 and the first wearing information meets the first threshold range, the counter 180 may zero the number of times recorded before and may start recording the wearing state once. In other words, the counter 180 in the embodiment of the present application may clear the number of times of recording the state before receiving the count of another state when the number of times of recording does not reach the corresponding threshold number of times.

When the wearable device 100 detects the current state, considering that under a single accidental scenario, there may be a situation that the processor 140 determines that the wearable device 100 is in a wearing state and the wearable device 100 is actually in a disengaging state according to the first detection module 120, the second detection module 130 (and the third detection module 170), and then if the wearable device 100 is considered to be in the wearing state in between, a misjudgment occurs.

The wearable device 100 of the embodiment of the present application continuously records the first number of times that the first wearing information meets the first threshold range through the counter 180, and as long as the first number meets the first number threshold, the processor 140 may ultimately consider that the wearable device 100 is in the wearing state, and perform corresponding control on the wearable device 100 based on the wearing state, and the processor 140 may control the wearable device 100 to be in the normal working mode according to the current state. Therefore, the wearable device 100 of the embodiment of the application can avoid misjudgment caused by single accidental, and the embodiment of the application can improve the accuracy of determining the current state of the wearable device 100.

Wherein, when the processor 140 outputs that the wearable device 100 is in the wearing state, the processor 140 may continue to determine whether the wearable device 100 is in the wearing state. Of course, the processor 140 may also control the first detection module 120 and the second detection module 130 (and the third detection module 170) to operate and determine whether the wearable device 100 is in the disengaged state.

Considering that after determining that the wearable device 100 is in the wearing state, the next concern is whether the wearable device 100 is in the disengaged state, so as to facilitate when the processor 140 changes the current working mode, if the disengagement detection is unsuccessful after the wearing state, the wearable device 100 may be considered to be in the wearing state all the time, and the processor 140 may maintain the current normal working mode all the time. Similarly, when it is determined that the wearable device 100 is in the disengaged state, the next concern is whether the wearable device 100 is in the worn state, so as to be convenient for the processor 140 to change the current working mode at any time, if the wearable device 100 is not successfully detected after the wearable device is in the disengaged state, the processor 140 can be considered to be always in the disengaged state, and the processor 140 can always maintain the current low-power working mode. Therefore, the wearable device 100 according to the embodiment of the present application may perform detection of the current state of the wearable device 100 in the manner of wear detection, detachment detection, wear detection, detachment detection … ….

It will be appreciated that when the wearable device 100 performs the detachment detection, the processor 140 may determine that the wearable device 100 is in the detachment state when the first wearing information does not conform to the first threshold range in the manner of the foregoing embodiment. Alternatively, processor 140 may determine that wearable device 100 is in the disengaged state when the first wear information does not meet the first threshold range and/or the second wear information does not meet the second threshold range. Of course, the processor 140 may determine whether the wearable device 100 is in the disengaged state according to other manners.

For example, an initial third threshold range corresponding to the first wearing information may be preset in the wearable device 100 according to experience or experiment, the third threshold range may be different from the first threshold range, and the processor 140 may determine that the wearable device 100 is in the disengaged state when the first wearing information conforms to the third threshold range.

It may be appreciated that the processor may further determine whether the first wearing information meets the third threshold range according to a preset second time interval, where the preset second time interval may be the same as or different from the first time interval in the foregoing embodiment, and the specific manner of the preset first time interval and the preset second time interval is not limited in this embodiment.

It will be appreciated that the processor may also input different pulse signals to the counter 180 according to the relationship between the first wearing information and the first and third threshold ranges, for example, when the first wearing information meets the first threshold range, the processor may transmit a high level pulse signal to the counter 180; when the first wear information meets the third threshold range, the processor may transmit a pulse signal of a low level to the counter 180. The counter 180 may continuously record, in addition to the first number of times the first wear information meets the first threshold range, a second number of times the first wear information meets the third threshold range, and the processor may determine that the wearable device is in the disengaged state when the second number of times meets the second number of times threshold.

It may be appreciated that, in the embodiment of the present application, the light detection module may be correspondingly provided with another environmental light threshold range different from the environmental light threshold range, and the biometric detection module 132 may be correspondingly provided with another biometric threshold range different from the biometric threshold range, and when performing detachment detection, the light detection module and the biometric detection module may perform judgment of the detachment state according to the other environmental light threshold range and the other biometric threshold range.

It is appreciated that in the disengagement detection, the processor 140 may also dynamically adjust the third threshold range of the first wear information based on the first ambient light information. The specific adjustment manner of the third threshold range may refer to the adjustment manner of the first threshold range, and will not be described herein.

It can be appreciated that the third threshold range may be a threshold range more suitable for the out-of-state, and the first threshold range may be a threshold range more suitable for the wearing state, and the present disclosure provides a more accurate determination of the current state of the wearable device 100 than a scheme that determines the state of the wearable device 100 according to the first threshold range only.
