Detailed Description

The technical solution in the embodiment of the present application will be clearly and completely described below with reference to fig. 1 to 10 in the embodiment of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the present 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 headset, and the like. The wearable device 100 of the embodiment of the present application is described by taking a smart watch as an example. Referring to fig. 1 to fig. 3, fig. 1 is a first structural schematic diagram of a wearable device 100 provided in the embodiment of the present application, fig. 2 is a structural schematic diagram of another perspective of the wearable device 100 provided in the embodiment of the present application, and fig. 3 is a second structural schematic diagram of the wearable device 100 provided in the 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 the user when the wearable device 100 is in a worn state, and the second region 112 is a region in contact with the user when the wearable device 100 is in a worn 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 detecting module 130 is disposed in the second area 112, and the second detecting module 130 can transmit the optical signal and detect the first wearing information of the wearable device 100 according to the optical signal. The processor 140 is electrically connected to the first detection module 120 and the second detection module 130 directly or indirectly, 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.

Wherein, the apparatus body 110 may include a main body 113, a first wearing portion 114 and a second wearing portion 115, and the first wearing portion 114 and the second wearing portion 115 may be directly or indirectly connected to both ends of the main body 113, respectively. The first wearing portion 114 and the second wearing portion 115 may fix the wearable device 100 to the body of the user, putting the wearable device 100 in a wearing state. The first and

second regions

111 and 112 may be, but are not limited to, regions on the main body 113, the first wearing portion 114, and the second wearing portion 115. For example, the first region 111 may be a region on the front or side of the main body 113, the first wearing portion 114, the second wearing portion 115; the second region 112 may be a region on the back of the main body 113, the first wearing portion 114, the second wearing portion 115. The back surface refers to a surface of the wearable device contacting with the skin of the 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 is understood that body 113 may form the main structure of wearable device 100 and may house some of the electronic components of wearable device 100. When the wearable device 100 is a smart watch, the body 113 may be a dial of the wearable device 100. Wherein, the main body 113 may be a cuboid, and then the wearable device 100 is a square dial; the main body 113 may also be a cylinder, and the wearable device 100 is a circular dial; the body 113 may also be an irregular polyhedron, and the wearable device 100 is an irregular dial. The embodiment of the present application does not limit the specific shape of the body 113.

It is understood that the first wearing portion 114 and the second wearing portion 115 may fix the main body 113 to a wrist, ankle, neck, etc. of the user, but are not limited thereto. When the wearable device 100 is a smart watch, the first wearing portion 114 and the second wearing portion 115 may be a band structure of the wearable device 100. The first wearing portion 114 and the second wearing portion 115 may be rotatably connected to both ends of the main body 113 by a rotation shaft, and the first wearing portion 114 and the second wearing portion 115 may also be fixedly connected to both ends of the main body 113 by an integral molding. The first wearing portion 114 and the second wearing portion 115 may be made of metal, plastic, nylon, or other non-metal materials. The materials of the first wearing portion 114 and the second wearing portion 115 can be set according to actual needs, and the embodiment of the present application is not limited.

The first detecting module 120 may be a detecting device that transmits an optical signal and can detect an ambient light parameter, for example, the first detecting 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, where the first ambient light information may include, but is not limited to, one or more of ambient light intensity, ambient light flux, ambient light illuminance, and ambient light color temperature. The first ambient light information may be indicative of ambient light information in the vicinity of the first area 111.

It is understood that the first detecting module 120 may be directly or indirectly connected to the first area 111, or the first detecting module 120 may be directly formed on the first area 111. Because the first region 111 is a region where the wearable device 100 and the user are spaced apart (not in contact) in the wearing state, the first region 111 is not blocked by the user in the wearing state, 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 a difference in the current environment of the wearable device 100. For example, when the external environment is a sunny day, the ambient light intensity detected by the first ambient light information is large; when the external environment is cloudy, the intensity of the ambient light detected by the first ambient light information is small.

It is understood that the first ambient light information may be related to visible light, and may also be 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 invisible light (such as, but not limited to, infrared light) to detect the first ambient light information. This is not limited in the embodiments of the present application.

The second detecting module 130 may be a detecting device that transmits the optical signal and detects the first wearing information of the wearable device 100 according to the optical signal. For example, the second detecting module 130 can be, but is not limited to, one or more of a photo sensor and a photoplethysmography detector.

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

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

It is understood that, in the initial state, the wearable device 100 may preset and store an initial first threshold range corresponding to the first wearing information according to experience or experiment. 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 adaptive to the current environment. For example, if the current environment is a sunny day, so that the first ambient light information is in the first range, the processor 140 may adjust the first threshold range smaller/larger based on the initial first threshold range; if the current environment is cloudy such that the first ambient light information is within the second range, the processor 140 may increase/decrease the first threshold range based on the initial first threshold range; if the current environment is cloudy weather such that the first ambient light information is in the third range, the processor 140 may not change the size of the first threshold range.

It should be noted that, the manner of dynamically adjusting the first threshold range by the processor 140 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 store a mapping table of the first ambient light information and the first threshold range in advance, 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 an initial first ambient light information corresponding to an initial first threshold range, and then the processor 140 may dynamically adjust the first threshold range according to a first corresponding relationship between the actual first ambient light information detected by the first detection module 120 and the initial first ambient light information, so that a second corresponding relationship between the adjusted first threshold range and the initial first threshold range is adapted to the first corresponding relationship. It is understood that the first corresponding relationship and the second corresponding relationship may correspond to, but are not limited to, a positive correlation, a negative correlation, an equal ratio, a square ratio, and an equal difference. The embodiment of the present application does not limit the specific manner of dynamically adjusting the first threshold.

It is understood 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 adaptive to the current environment. For example, when the first wearing information meets the first threshold range, the processor 140 may consider that the wearable device 100 is in a wearing state; when the first wearing information does not meet the first threshold range, the processor 140 may consider the wearable device 100 to be in the detached state. Here, 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 or the connection is not compliant with the standard, and at this time, the second region 112 of the device body 110 is not in contact with the user, and the first region 111 may be in contact with or not in contact with the user.

It should be noted that, a threshold range of a detection module for detecting a 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 may occur, so that the determination of the wearing state is inaccurate. For example, when the external environment is dark, even if the wearable device 100 is in the detached state, the detection module determines that the wearable device 100 is in the wearing state when determining 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 that the wearable device 100 is in the disengaged state when determining according to the fixed threshold range. Thus, the determination of the current state of the related art wearable device 100 is inaccurate.

In the wearable device 100 of the embodiment of the application, the first detection module 120 is disposed in the 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 of the wearable device 100 in the current environment; the second detecting module 130 is disposed in the second area 112 contacting with the user in the wearing state of the wearable device 100, and the first wearing information detected by the second detecting module 130 may indicate a 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, wherein 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 may be adapted to the current environment of the wearable device 100, and in any scene, the situation that the wearing state detection is accidentally disabled due to the change of the environment does not occur, so that the wearing state of the wearable device 100 is more accurately judged in the embodiment of the present application.

After the processor 140 determines that the wearable device 100 is in the wearing state or the detached state, the processor 140 may control the wearable device 100 to execute a corresponding operation mode according to the wearing state or the detached state. For example, when the wearable device 100 is in a wearing state, the processor 140 may control the wearable device 100 to enter a normal operation 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 can be understood that the normal operation mode may be that the wearable device 100 executes its standard power consumption mode, and may implement functions of video, audio playing, navigation, shooting, and the like through software support and data interaction and cloud interaction. For example, when the wearable device 100 is a smart headset, its normal operating mode is to execute a play audio mode; when the wearable device 100 is an intelligent glasses or an intelligent helmet, the normal working mode thereof may be modes of performing intelligent display, taking a picture, playing a video, map navigation, and the like; when the wearable device 100 is a smart watch, its normal operating mode may be time display, mobile payment, video chat, real-time positioning, real-time step counting, physiological characteristic monitoring, etc.

It is understood that the low power consumption mode may mean that the power consumption of the wearable device 100 is less than the standard power consumption, i.e. lower than the normal power consumption. That is, the power consumption of the wearable device 100 when operating in the low power consumption mode is less than the power consumption of the wearable device 100 when operating in the normal operating 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 application can execute the normal operation mode or the low power consumption mode according to the current state of the wearable device, and the wearable device 100 does not need to be always in the high power consumption normal operation mode, so that the power consumption of the wearable device 100 is low.

Wherein, referring again to fig. 1 and 3, the wearable device 100 may further include a display screen 150.

The display screen 150 may be installed 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, so as to be used for displaying information such as images and texts by the wearable device 100, or simultaneously used for displaying images and texts and for human-computer interaction by 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 (LCD) or an Organic Light-Emitting Diode (OLED) Display.

It is understood that the display screen 150 may include a display area and a non-display area. The display area executes a display function of the display screen 150, and is used for displaying information such as images and texts for 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 in full screen, so that the wearable device 100 has a larger screen ratio. The display screen 150 includes only a display region and does not include a non-display region, or the non-display region has a small area for a user. At this time, functional components such as a camera, a proximity sensor, and the like in the wearable device 100 may be hidden under the display screen 150.

Here, 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. Memory 160 stores applications containing executable code. The application programs may constitute various functional modules. The processor 140 executes various functional applications and data processing by running an application program stored in the memory 160. It is understood that the specific structure of the memory 160 can be referred to the description of the related art, and will not be described in detail herein.

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

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

The light detection module 131 may transmit the light signal and may detect the second ambient light information of the wearable device 100 according to the light signal, at this 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-sensitive sensors (e.g., ambient light sensors). The light detection module 131 may detect second ambient light information in the vicinity of the second area 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 light illuminance, ambient light color temperature. The second ambient light information may be indicative of ambient light information in the vicinity of the second area 112.

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

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 indicates that the current environment is in a state of strong illumination (sunny state), the processor 140 may dynamically decrease the ambient light threshold range, so that the processor 140 does not falsely determine the wearing state as the disengaged state; for another example, when the first ambient light information indicates that the current environment is in a low-light state (rainy state), the processor 140 may dynamically adjust the ambient light threshold range to be large, so that the processor 140 does not confirm the off-state as the wearing state.

The manner of dynamically adjusting the ambient light threshold range according to the first ambient light information is not limited to the above example, and may be dynamically adjusted by, but not limited to, a mapping table, a positive correlation, a negative correlation, an geometric relation, a square ratio relation, an arithmetic difference relation, and the like in the foregoing embodiment. This is not limited in the embodiments of the present application.

After adjusting the ambient light threshold, the processor 140 may determine that the wearable device 100 is in a worn state when the second ambient light information meets the ambient light threshold range. Processor 140 may determine that 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 manners, which is not limited in this embodiment.

The wearable device 100 of the embodiment of the application, first detection module 120 can detect the first ambient light information of the first region 111, second detection module 130 can detect the second ambient light information of the second region 112, first detection module 120 and second detection module 130 can both detect the ambient light information, thereby, after processor 140 adjusts the ambient light threshold range corresponding to the second ambient light information according to the first ambient light information, this ambient light threshold range can more adapt to current environment, the judged result of the current state of the wearable device 100 is more accurate.

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

The first and

second photodetectors

1311, 1312 may be photo sensors. The second region 112 of the apparatus 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, the first detector may be disposed at the first sub-region 1121, the 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 the 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, on the back of the first wearing portion 114; the second sub-region 1122 may be formed on the second wearing portion 115, for example, on the back surface of the second wearing portion 115. When the wearable device 100 is in a wearing state, the first sub-region 1121 and the second sub-region 1122 can be in close fit with a user. Of course, the first sub-region 1121 and the second sub-region 1122 can also be formed in other regions of the wearable device 100, for example, the first sub-region 1121 and the second sub-region 1122 can be disposed at intervals on the main body 113. This is not particularly limited in the examples of the present application.

It is understood that the first and

second sub-regions

1121 and 1122 may be symmetrically disposed about the central axis L0 of the device body 110, so that the first and second

light detectors

1311 and 1312 may be symmetrically disposed, and at this time, the first and second

light detectors

1311 and 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 also be asymmetrically disposed, which is not limited in this embodiment of the application.

It is understood that the first photo detector 1311 and the second photo detector 1312 may be the same type of photo sensor, or may be different types of photo sensors. This is not particularly limited in the examples of the present application.

The first photo detector 1311 may detect first sub-ambient light information of the first sub-region 1121, and the second photo detector 1312 may detect second sub-ambient light information of the second sub-region 1122. Processor 140 may adjust a first sub-threshold range corresponding to first sub-ambient light information detected by first photodetector 1311 based on the first ambient light information, or may adjust a second sub-threshold range corresponding to second sub-ambient light information detected by second photodetector 1312 based on the first ambient light information. Meanwhile, the processor 140 may also 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 wearing 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; processor 140 may also determine that 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 also be determined according to the difference between the first sub-ambient light information and the first sub-threshold range and the difference between the second sub-ambient light information and the second sub-threshold range. This is not particularly limited in the examples of the present application.

According to the wearable device 100 provided by the embodiment of the application, the first light detector 1311 and the second light detector 1312 are symmetrically arranged, and 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, so that accidental errors caused by single-point detection due to the movement of the hand of the user can be avoided, and the state determination result of the wearable device 100 provided by the embodiment of the application is more accurate.

It should be noted that, in other embodiments, the light detection module 131 of the embodiment of the present application may further include at least one additional light detector in addition to the first light detector 1311 and the second light detector 1312, and the plurality of light detectors are distributed in different regions at intervals and jointly detect the second ambient light information of the second region 112, in this case, 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 a biometric threshold range.

It is understood that the biometric detection module 132 may be, but is not limited to, one or more of a photoplethysmography detector, an optical heart rate detector, a temperature sensor, an electrocardiography (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 uptake, blood pressure, etc.

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

It is understood that the second detection module 130 may include both the light detection module 131 and the biometric detection module 132, and the light detection module 131 and the biometric 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 in the third sub-region 1123, and the third sub-region 1123 may be, but is not limited to, a region of the back side of the subject 113. The processor 140 may synthetically determine the current state of the wearable device 100 from the relationship of the second ambient light information to the ambient light threshold range and the relationship of the biometric information to the biometric threshold range.

For example, the processor 140 may determine that the wearable device 100 is in the wearing 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 disengagement state of the wearable device 100 in other ways, which is not limited in this embodiment.

It is to be understood that the processor 140 may adjust the 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 relationship between the biometric information and the biometric threshold range. Of course, the order of the above steps of the processor 140 may be arbitrarily adjusted. This is not limited in the embodiments of the present application.

In the wearable device 100 of the embodiment of the application, the second detection module 130 includes the light detection module 131 and the biometric 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 biometric information detected by the biometric detection module 132, so that the determination of the current state of the wearable device 100 is more accurate.

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 biometric threshold range corresponding to the biometric information according to the first ambient light information, so that the biometric threshold range may be adapted to the current environment.

The wearable device 100 may preset a biometric threshold range according to experience or experiment, and then the processor 140 may dynamically adjust the biometric threshold range according to the first ambient light information detected by the first detection module 120 by using a mapping relation table, a positive correlation relation, a negative correlation relation, an equal ratio relation, a square ratio relation, an equal difference relation, and the like. The specific adjustment manner is not limited in the embodiments of the present application.

After 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 disengagement state of the wearable device 100 in other ways, which is not limited in this embodiment.

In the wearable device 100 of the embodiment of the application, the biometric detection module 132 may transmit the optical signal and detect the biometric information of the second area 112 according to the optical signal, on one hand, whether the user wears the wearable device 100 may be determined more accurately according to the biometric parameters detected by the biometric 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 is more adaptable 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 determined more accurately.

It should be noted that, in the embodiment of the present application, the second detection module 130 may include both the light detection module 131 and the biometric 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 the optical signal and may detect the 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 the 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 the wearing state when the biometric information conforms to the biometric threshold range. The detailed operation of the biometric characteristic detection module 132 and the processor 140 can be referred to the description of the foregoing embodiments, which are not repeated herein.

Referring to fig. 2 again, the biometric detection module 132 according to the embodiment of the present disclosure may be a photoplethysmography detector.

The photoplethysmography detector may include one or more light emitters 1321 and a plurality of light receivers 1322, 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 optical receivers 1322 may be uniformly and spaced around the one or more optical transmitters 1321.

The light emitter 1321 can emit a light signal in the direction of the user, the light signal is reflected by skin tissue after encountering the skin of the user to form a reflected light signal, the reflected light signal is received by the light receiver 1322 and converted into an electric signal, and since the absorption of the light by the tissues such as muscles, bones, veins and the like of the human body is basically unchanged, but the flow of blood can absorb part of the light signal, the characteristics of the flow of blood can be reflected by extracting the alternating current AC signal and the direct current DC signal in the electric signal formed by analyzing the reflected light signal. And then it can be determined whether the wearable device 100 is worn by the user.

It is to be understood that the optical transmitter 1321 may be an led structure and the optical receiver 1322 may be a photodiode structure. When the photoplethysmography detector includes a plurality of light emitters 1321, the 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 spaced apart from each other, so that light of different colors may be prevented from being mixed.

It is understood that, since the photoplethysmography detector needs to emit the optical signal and detect the biometric information of the user according to the optical signal, the processor 140 may dynamically adjust a 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, but is not limited to, at least one of pulse wave information, blood oxygen information, heart rate information, blood pressure information, and the like, and correspondingly, the biometric threshold range may be, but is not limited to, at least one of pulse wave threshold range, blood oxygen threshold range, heart rate threshold range, blood pressure threshold range, and the like.

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 based on 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; if the current environment is cloudy such that the first ambient light information is in the third range, the processor 140 may not change the size of the biometric threshold range.

In addition to the above embodiments, the processor 140 may dynamically adjust the biometric threshold range according to the first ambient light information detected by the first detection module 120 by using a mapping relation table, a positive correlation relation, a negative correlation relation, an equal ratio relation, a square ratio relation, an equal difference relation, and the like. The embodiments of the present application are not limited herein.

The biometric feature detection module 132 of the embodiment of the present application is a photoplethysmography detector, which can detect biometric information of a user, such as blood oxygen, on one hand, so as to monitor physiological features of the user; on the other hand, the photoplethysmography 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 photoplethysmography detector of the embodiment of the application realizes multiplexing, can save the production cost of the wearable device 100, and can also realize the miniaturization design of the wearable device 100.

Please refer to fig. 4 and fig. 5, in which 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 detecting module 170 may be disposed on the device body 110, for example, on the main body 113, the first wearing portion 114, and the second wearing portion 115. When the wearable device 100 is normally worn on the user, the third detection module 170 may be in contact with the user or separated from the user, and the specific setting position of the third detection module 170 may be adapted to the 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 empirically or experimentally 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 uptake information, blood pressure information, bio-impedance information, etc. of the user. Accordingly, the third detecting 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 Electrocardiography (ECG) detector, and a bioimpedance detector. For example, as shown in fig. 4, when the third detecting module 170 is an electrocardiograph detector or a bioimpedance detector, a plurality of ECG electrodes or a plurality of bioimpedance measuring electrodes corresponding thereto may be spaced around the periphery of the capacitance volume pulse wave detector. It is understood that the specific manner of detecting the second wearing information by the third detecting module 170 may be different according to the type of the third detecting module 170, for example, the temperature sensor may detect the resistance value of the thermistor according to the temperature variation principle, or may detect the second wearing information by using the thermoelectric effect of the infrared thermopile; for another example, the pressure sensor can detect the pressure by using the principle that the piezoresistive or piezoelectric material generates different electrical signals under different forces. The embodiment of the present application does not limit the specific operation manner of the third detection module 170.

The third detecting 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 wearing state when the first wearing information meets the first threshold range and the second wearing 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 wearing information does not meet the first threshold range, and/or the second wearing information does not meet the second threshold range. Of course, the way in which the processor 140 determines that the wearable device 100 is in the detached state is not limited thereto, and the embodiment of the present application does not limit this.

The wearable device 100 of the embodiment of the application, the processor 140 can further determine according to the second wearing information of the third detection module 170 after determining that the wearable device 100 is in the wearing state preliminarily according to the first detection module 120 and the second detection module 130, thereby the wearable device 100 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, the determination error caused by accidental invalidation can be avoided, and the determination of the current state of the wearable device 100 is more accurate.

Please refer to fig. 6, wherein fig. 6 is a fifth structural schematic diagram of the wearable device 100 according to the embodiment of the present application. Wearable device 100 may also include a counter 180.

The counter 180 may be in direct or indirect electrical communication with 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 preset 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 also 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, when the first wearing information meets the first threshold range, the processor may transmit a pulse signal of a high level to the counter; when the first wearing information does not meet the first threshold range, the processor may transmit a pulse signal of a low level to the counter. The counter 180 may count the number of different input pulses, so that the counter 180 may record the number of times that the first wearing information conforms to the first threshold range, and the counter 180 may also record the number of times that the first wearing information does not conform to 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 a function of storing information. It should be noted that, the specific structure of the counter 180 may refer to the description of the related art, and will not be described here.

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

It can be understood that, if the counter 180 receives the pulse signal transmitted by the processor 140 all the time when the first wearing information meets the first threshold range and the first time does not meet the first time threshold, at this time, if the counter 180 receives the pulse signal transmitted by the processor 140 when the first wearing information does not meet the first threshold range, the counter 180 may zero the previously recorded first time and may start recording the one-time out-of-state. Similarly, if the counter 180 receives the pulse signal that the first wearing information transmitted by the processor 140 does not conform to the first threshold range and the number of times of the pulse signal does not conform to the corresponding number threshold, at this time, if the counter 180 receives the pulse signal that the first wearing information transmitted by the processor 140 conforms to the first threshold range, the counter 180 may clear the number of times recorded before, and may start to record a wearing state once. In other words, the counter 180 of the embodiment of the present application may reset the number of times of the previous recording state when the number of times of recording does not reach the corresponding threshold number of times and receives the count of another state.

When the wearable device 100 detects the current state, considering that in a single accidental scenario, the processor 140 may determine that the wearable device 100 is in the wearing state and the wearable device 100 is in the detached state according to the first detection module 120, the second detection module 130 (and the third detection module 170), and at this time, if the wearable device 100 is considered to be in the wearing state, a determination error may occur.

The wearable device 100 of the embodiment of the present application continuously records, by the counter 180, the first number of times that the first wearing information meets the first threshold range, as long as when the first number of times meets the first number of times threshold, the processor 140 finally considers that the wearable device 100 is in the wearing state and performs 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 operating mode according to the current state. Therefore, the wearable device 100 of the embodiment of the application can avoid misjudgment of single contingency, and the embodiment of the application can improve the accuracy of determining the current state of the wearable device 100.

Wherein, after 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 detached 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 detachment state to facilitate when the processor 140 changes the current operating mode, if the detachment detection is unsuccessful after the wearing state, the wearable device 100 may be considered to be in the wearing state, and the processor 140 may maintain the current normal operating mode. Similarly, when it is determined that the wearable device 100 is in the detached state, the next concern is whether the wearable device 100 is in the worn state to facilitate when the processor 140 changes the current operating mode, and if the wearable detection is unsuccessful after the detached state, the wearable device 100 may be considered to be in the detached state, and the processor 140 may maintain the current low power consumption operating mode. Therefore, the wearable device 100 of the embodiment of the present application can perform detection of the current state of the wearable device 100 in the manner of wearing detection → detachment detection → wearing detection → detachment detection … ….

It is to be understood 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 meet the first threshold range in the manner of the foregoing embodiment. Alternatively, the processor 140 may determine that the wearable device 100 is in the disengaged state when the first wearing information does not meet the first threshold range, and/or the second wearing 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 ways.

For example, an initial third threshold range corresponding to the first wearing information may be preset in the wearable device 100 empirically or experimentally, 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 meets the third threshold range.

It is understood 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 of the application.

It is understood 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 threshold range and the third threshold range, for example, when the first wearing information conforms to the first threshold range, the processor may transmit a high-level pulse signal to the counter 180; when the first wearing 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 a second number of times that the first wearing information meets a third threshold range, in addition to the first number of times that the first wearing information meets the first threshold range, and the processor may determine that the wearable device is in the detached state when the second number of times meets the second number threshold.

It is understood that, in the embodiment of the present application, the light detection module may be correspondingly provided with another ambient light threshold range different from the ambient 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 the detachment detection, the light detection module and the biometric detection module may perform the determination of the detachment state according to the another ambient light threshold range and the another biometric threshold range.

It is to be understood that in the detachment detection, the processor 140 may also dynamically adjust the third threshold range of the first wearing information according to 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 is not described herein again.

It is understood that the third threshold range may be a threshold range more suitable for the detached state, and the first threshold range may be a threshold range more suitable for the wearing state, and the scheme of setting the two threshold ranges is more accurate for determining the current state of the wearable device 100 than the scheme of determining the state of the wearable device 100 only according to the first threshold range.
