The specific wearing detection method is explained in detail in the following embodiments.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a wear detection method according to an embodiment of the present application. The wearing detection method is used for determining the state of the wearable device according to inertial data detected when the wearable device is worn, obtaining target acceleration along a set direction according to the first acceleration when the state of the wearable device is a motion state or a vertical hand rest state, and determining that the current wearing mode of the wearable device is a left-hand mode or a right-hand mode according to the target acceleration in the set direction. The following will take the wearable device as an example to describe a specific process of the present embodiment, and it can be understood that the wearable device applied in the present embodiment may be a bracelet, a watch, and the like, which is not limited herein. The following will describe the flow shown in fig. 1 in detail, wherein in this embodiment, the wearing detection method may specifically include the following steps:
step S110: inertial data detected while the wearable device is worn is obtained.
In this application embodiment, the wearable device being worn means that the wearable device is worn on the left or right hand of the user. The inertial data may include one or more of acceleration data, magnetic sensing data, and angular velocity data.
The above manner of acquiring the inertial data may be to acquire the inertial data detected by an inertial sensor provided inside the wearable device, where the inertial sensor may include at least one of a three-axis magnetic sensor, a three-axis acceleration sensor, and a three-axis gyroscope.
In the present embodiment, when the wearable device includes at least one of the inertial sensor including a three-axis magnetic sensor, a three-axis acceleration sensor, and a three-axis gyroscope, the inertial data detected by the inertial sensor has detection data in three directions along the measurement space coordinate, and the detection data in each direction is at least one.
In some embodiments, when the inertial sensors comprise three-axis acceleration sensors, the corresponding obtained acceleration data comprises x-axis acceleration, y-axis acceleration, z-axis acceleration at measurement space coordinates of the wearable device; when the inertial sensor comprises a three-axis gyroscope, the angular velocity data correspondingly obtained comprises an x-axis angular velocity, a y-axis angular velocity and a z-axis angular velocity under the measurement space coordinate; when the inertial sensor comprises a three-axis magnetic sensor, the correspondingly obtained magnetic sensing number comprises an x-axis magnetic field strength, a y-axis magnetic field strength and a z-axis magnetic field strength under the measurement space coordinate. The x-axis, y-axis, and z-axis are determined according to the relative positions of the inertial sensors when the inertial sensors are mounted on the wearable device. It should be understood that when the inertial sensor includes at least two of the three-axis acceleration sensor, the three-axis gyroscope, and the three-axis magnetic sensor, the detection data in each direction along the measurement space coordinate is also at least two.
As shown in fig. 2, in this embodiment, when the wearable device is a smart watch or a smart bracelet, and the upper surface of the chip of the inertial sensor is parallel to the display screen of the smart watch, the x-axis in the measurement space coordinate of the wearable device may be in the width direction of the wearable device, the z-axis in the measurement space coordinate may be in the vertical direction perpendicular to the display screen of the wearable device, and the y-axis in the measurement space coordinate may be in the longitudinal direction perpendicular to the width direction and the vertical direction (when the wearable device is a watch or a bracelet, the y-axis in the measurement space coordinate is in the length direction when the wearable device is unfolded).
Step S120: and obtaining the state of the wearable equipment according to the inertial data.
In this example, the state of the wearable device may include: a motion state and a rest state, and the rest state includes a hand drop rest state. The motion state is used for representing that when the wearable device is worn on a user, the user is in a motion state such as walking and running, and the wearable device is in the motion state; the standing-hand rest state is used for representing that when the wearable device is worn on the left hand or the right hand of a user, the state of the hand of the user wearing the wearable device is a rest standing-hand state, such as a rest standing-hand state or a rest sitting-lying-hand state.
The obtaining of the state of the wearable device according to the inertial data may be determining that the wearable device is in a stationary state or a moving state according to one or more of acceleration data, magnetic sensing data, and angular velocity data in the inertial data, and determining that the wearable device is in a overhand stationary state according to at least two of the acceleration data, the magnetic sensing data, and the angular velocity data when the wearable device is in the stationary state.
In some embodiments, when the inertial data includes a plurality of sets of acceleration data, determining a state of the wearable device according to accelerations of the plurality of sets of acceleration data in three directions, respectively, wherein when a variance or a standard deviation of acceleration values of the plurality of sets of acceleration data in each direction is smaller than a corresponding preset threshold value, or the accelerations of the plurality of sets of acceleration data in each direction are within a corresponding preset acceleration value range, it may be determined that the wearable device is in a stationary state; when the inertial data comprise multiple groups of magnetic sensing data, determining the state of the wearable device according to the magnetic field strengths of the multiple groups of magnetic sensing data in three directions respectively, wherein when the variance or standard difference of the magnetic field strengths of the multiple groups of magnetic sensing data in each direction is smaller than a corresponding preset threshold value respectively, or the magnetic field strengths of the multiple groups of magnetic sensing data in each direction are in a corresponding preset strength value range respectively, determining that the wearable device is in a static state; when the inertial data include multiple sets of angular velocity data, determining the state of the wearable device according to the angular velocities of the multiple sets of angular velocity data in the three directions, wherein when the variance or standard difference of the angular velocities of the multiple sets of angular velocity data in each direction is smaller than a corresponding preset threshold value, or the angular velocities of the multiple sets of angular velocity data in each direction are within a corresponding preset angular velocity value range, it may be determined that the wearable device is in a stationary state.
Referring to fig. 3, fig. 4 and fig. 5, the inertia data is exemplified by a plurality of sets of acceleration data, as shown in fig. 3, since the wearable device swings with the right hand 10 or the left hand 20 of the user when the wearable device is in a motion state (i.e., the user wearing the wearable device is in the motion state), the acceleration data acquired by the wearable device has accelerations in three directions (x direction, y direction and z direction), and the acceleration in each direction changes with time, so that the acceleration values of the obtained plurality of sets of acceleration data in the three directions may be different. When the wearable band device is worn in the left hand (as shown in fig. 4) and in the right hand (as shown in fig. 5) in the stationary state, the plurality of sets of acceleration data acquired in the above two states are the same and include the acceleration in the direction of gravity. The variance or standard deviation of the multiple groups of acceleration data can be obtained by calculating the variance or standard deviation of the acceleration in each direction, when the variance or standard deviation of the multiple groups of acceleration data is larger than or equal to the corresponding preset threshold value, the wearable device can be determined to be in a motion state, and when the variance or standard deviation of the multiple groups of acceleration data is smaller than the corresponding preset threshold value, the wearable device can be determined to be in a static state.
When the wearable device is in the stationary state and whether the wearable device is in the stationary state of the vertical hand is determined, the attitude angle of the wearable device can be calculated according to the magnetic sensing data and the acceleration data included in the inertial data, and when the attitude angle is within the preset attitude angle threshold range, the wearable device can be confirmed to be in the stationary state of the vertical hand.
Specifically, when the wearable device is in a standing still state, the direction pointed by the acceleration data is always the same as or opposite to the gravity, the direction pointed by the magnetic sensing data is always pointed to the south, the attitude angle of the wearable device can be obtained by calculating according to the acceleration data and the magnetic sensing data by adopting a Kalman filtering algorithm, and when the attitude angle is within a preset threshold range, the wearable device can be confirmed to be in the standing still state.
Step S130: when the state of the wearable device is a motion state or a vertical hand rest state, first acceleration data is acquired.
The first acceleration data may be acceleration data in the inertial data, or triaxial acceleration data detected by a triaxial acceleration sensor included in the inertial sensor, which is obtained after determining the state of the wearable device according to the inertial data.
In this embodiment, the first acceleration data includes accelerations in three directions, and the three directions corresponding to the first acceleration data are the same as the three directions corresponding to the acceleration data included in the inertia data. That is, in the present embodiment, the accelerations of the first acceleration data in the three directions include a wide acceleration in a width direction (in the x-axis direction) of the wearable device, a vertical acceleration value in a vertical direction (in the z-axis direction) perpendicular to the display screen of the wearable device, and a long acceleration value in a long direction (in the y-axis direction) perpendicular to the vertical direction and the width direction as in fig. 2.
The acquired first acceleration data may include only one set of acceleration data, or may include a plurality of sets of acceleration data. For example, when the state of the wearable device is a stationary state, the acquired first acceleration data may include one set of acceleration data, and when the state of the wearable device is a motion state, multiple sets of acceleration data, such as at least two sets of acceleration data, may be acquired.
Step S140: and obtaining a target acceleration along a set direction according to the first acceleration data, and determining a current wearing mode of the wearable device according to the target acceleration along the set direction, wherein the current wearing mode comprises a left-hand mode or a right-hand mode.
In some embodiments, the setting direction may be along the width direction of the wearable device, or may be a direction having an angle within a preset angle range with the width direction, for example, the setting direction may be any direction having an angle within a range of less than or equal to 30 degrees with the width direction.
When the target acceleration in the set direction is obtained from the first acceleration data, the accelerations of the first acceleration data in the three directions may be respectively converted into the directions along the set direction to obtain the target acceleration in the set direction.
In some embodiments, the wearable device may store a preset acceleration value range corresponding to the left-hand mode and the left-hand mode in the target direction, and an acceleration value range corresponding to the right-hand mode and the right-hand mode in the target direction, so that the current wearing mode of the wearable device may be determined to be the left-hand mode or the right-hand mode, that is, the wearable device is worn in the left hand or the right hand of the user, by using the correspondence relationship and the obtained target acceleration in the set direction.
Taking the setting direction as an example along the width direction of the wearable device, when the wearable device is in the same motion state or static state, the target acceleration values in the setting direction obtained in the left-hand mode and the right-hand mode respectively are opposite, as shown in fig. 4, when the wearable device is in the vertical-hand static state and the wearing mode is the left-hand mode, the target acceleration value in the setting direction (x-axis direction in the measurement space coordinate) is opposite to the gravity acceleration, and is-g; as shown in fig. 5, when the wearable device is in the vertical hand rest state and the wearing mode is the right-hand mode, the target acceleration value in the set direction (x-axis direction in the measurement space coordinate) is the gravitational acceleration g.
According to the wearing detection method provided by the embodiment, when the wearable device is worn and the state of the wearable device is a motion state or a vertical hand rest state, the current wearing mode of the wearable device is determined to be the left-hand mode or the right-hand mode according to the acceleration value of the acquired first acceleration data in the target direction. In addition, when the current wearing mode of detecting wearable equipment is left hand mode or right hand mode, be in operating condition and hang hand quiescent condition at wearable equipment and all can detect, consequently, very big improvement the convenience that wearable equipment state detected and need not user operation and then can promote user experience, in the testing process, only need obtain a set of or multiunit first acceleration data for the testing process of wearing the detection method is efficient.
In some embodiments, after the current wearing mode of the wearable device is determined, when the pre-stored wearing mode is inconsistent with the current wearing mode, the pre-stored wearing mode is adjusted to the current wearing mode, so that the condition that data detection such as blood pressure and blood oxygen is inaccurate due to the inconsistency between the pre-stored wearing mode and the current wearing mode can be relieved, and the accuracy of the functions of the wearable device is improved.

Referring to fig. 3, 4 and 5 again, in the step S240, the acceleration of the wearable device in three directions is expressed in the measurement space coordinates of the wearable device, so as to obtain the acceleration in the x-axis direction (the wide-direction acceleration in the width direction), the acceleration in the z-axis direction (the vertical-direction acceleration perpendicular to the display screen of the wearable device), and the acceleration in the y-axis direction (the long-direction acceleration perpendicular to the wide-direction and the vertical-direction) and convert the accelerations in the x-axis direction, the y-axis direction and the z-axis direction to the setting directions, respectively, so as to obtain the acceleration value in the setting direction. When the set direction is the positive x-axis direction, the current wearing mode of the wearable device is a right-hand mode and is in a motion state or a vertical-hand static state, and the positive x-axis direction swings left and right in the gravity direction or is the same as the gravity direction, so that the calculated acceleration in the set direction approaches to the gravity acceleration g; the current wearing mode of the wearable device is the left-hand mode and the positive x-axis direction swings left and right in the direction opposite to the direction of gravity or opposite to the direction of gravity in the moving state or the vertically stationary state, and therefore the acceleration in the calculated set direction approaches-g.
