The embodiment of the present application can realize accurate detection of the wearing hand state of the wearable device 201, with low cost, simplicity and reliability.

[0024] The execution subject of the wearing state detection method provided in the embodiment of the present application can be a wearable device 201, or a wearing state detection device. Among them, the wearing state detection device can be applied to the wearable device 201, the wearing state detection device can be a module in the wearable device 201, and can also be a component in the wearable device 201, such as an integrated circuit or a chip or a central processing unit, etc. The wearable device 201 can be a terminal, or it can be other devices other than a terminal. Exemplarily, the above-mentioned wearable device 201 includes but is not limited to: Bluetooth headsets, smart audio glasses, wearable speakers, smart helmets, etc.

[0025] The present application embodiment provides a wearing status detection method, which is applied to a wearable device 201, such as Figure 1 and Figure 3 As shown, the wearing state detection method may include the following steps S100, S110 and S120:

[0026] Step S100 : transmitting a first signal SIG 1 via the signal transmitter 202 .

[0027] The first signal SIG 1 emitted by the signal transmitter 202 is a sound wave signal, which may be an ultrasonic wave signal or other sound wave signals that can reflect the contour of an object on a reflective surface. The wearable device 201 includes a processor 204. The manner of emitting a signal through the signal transmitter 202 includes but is not limited to the following manners: the wearable device 201 controls the signal transmitter to emit the first signal SIG 1; the processor 204 in the wearable device 201 controls the signal transmitter 202 to emit the first signal SIG 1; the signal transmitter 202 emits the first signal SIG 1 by itself.

[0028] The triggering method for transmitting the first signal SIG 1 includes but is not limited to the following methods: the wearer sends specific instructions, command programs, etc. to the processor 204, so that the processor 204 controls the signal transmitter 202 to transmit the first signal SIG 1; automatically transmits the sound wave signal at a preset time interval; the signal transmitter 202 transmits automatically after detecting the corresponding human body part, etc.

[0029] It should be noted that the processor 204 can be a microprocessor, a central processing unit or a graphics processor, etc., which is not specifically limited in this application; the signal transmitter 202 can be a device or sensor that transmits sound wave signals, such as a speaker, a loudspeaker, a sound, and a sound wave transmitter, which is not specifically limited in this application. The processor 204 can control various sensors, devices or storage devices in the wearable device 201 through signal transmission, instruction sets, electrical signals, etc. The processor 204 can also be used for processing and calculation to obtain various data information, which is not specifically limited in this application.

[0030] Step S110: receiving a second signal SIG 2 through the signal receiver 203, where the second signal SIG 2 is a reflection signal of the first signal SIG 1 reflected by a body part of the user wearing the wearer.

[0031] In the embodiment of the present application, the first signal SIG 1 is a sound wave signal. The first signal SIG 1 is transmitted to the body part of the wearer. The sound wave signal is reflected after contacting the body part of the wearer. The sound wave signal reflected by the body part of the wearer is the second signal SIG 2, and the second signal SIG 2 is the reflection signal of the first signal SIG 1. The signal receiver 203 can be a device or sensor for receiving sound waves such as a microphone, a receiver, etc., and is not specifically limited in the present application.

[0032] Step S120: acquiring shape information of the body part and distance information between the wearable device 201 and the body part according to the second signal SIG 2; and determining the wearing state of the wearable device 201 according to the shape information and the distance information.

[0033] In the embodiment of the present application, the second signal SIG 2 is a reflected sound wave signal. The distance information can be calculated using the time difference between transmitting the first signal SIG1 and receiving the second signal SIG 2 using the propagation speed of the sound wave signal. By processing the amplitude, frequency and waveform of the second signal SIG 2 sound wave through the processor 204, information such as the shape, size, shape, and outline of the reflecting surface or reflecting object can be obtained.

[0034] Reference Figures 2 to 5 In the embodiment of the present application, step S100, transmitting the first signal SIG 1 through the signal transmitter 202, also includes: when the signal transmitter 202 is toward the arm side, transmitting the first signal SIG 1 to the arm through the signal transmitter 202; when the signal transmitter 202 is toward the body side, transmitting the first signal SIG 1 to the body through the signal transmitter 202; when the signal transmitter 202 is toward the back of the hand side, transmitting the first signal SIG 1 to the back of the hand through the signal transmitter 202.

[0035] In the embodiment of the present application, when the wearer wears the wearable device 201, the signal transmitter 202 faces the arm. Therefore, after the first signal SIG 1 is transmitted through the signal transmitter 202, the sound wave of the first signal SIG 1 propagates to the arm and is reflected, and the second signal SIG 2 is a reflection signal reflected by the arm; when the wearer wears the wearable device 201, the signal transmitter 202 faces the back of the hand. Therefore, after the first signal SIG 1 is transmitted through the signal transmitter 202, the sound wave of the first signal SIG 1 propagates to the back of the hand and is reflected, and the second signal SIG 2 is a reflection signal reflected by the back of the hand; when the wearer wears the wearable device 201, the signal transmitter 202 faces the torso. Therefore, after the first signal SIG 1 is transmitted through the signal transmitter 202, the sound wave of the first signal SIG 1 propagates to the torso and is reflected, and the second signal SIG 2 is a reflection signal reflected by the torso.

[0036] Optionally, in the embodiment of the present application, the step S120 of “obtaining shape information of the body part and distance information between the wearable device 201 and the body part according to the second signal SIG 2” may include step S120a.

[0037] Step S120a, calculating the time difference between the transmission time of the first signal SIG 1 and the reception time of the second signal SIG 2, and obtaining distance information according to the time difference; processing the frequency, waveform and amplitude of the second signal SIG 2 to obtain shape information.

[0038] In the embodiment of the present application, step S120a is used to obtain distance information and appearance information according to various information of the first signal SIG 1 and the second signal SIG 2. The processor 204 in the wearable device 201 can calculate the time difference between the transmission time of the first signal SIG 1 and the reception time of the second signal SIG 2. The first signal SIG 1 and the second signal SIG 2 are both sound wave signals. The distance information between the body part and the wearable device 201 can be calculated by the propagation speed of the sound wave signal in the air and the above time difference; the processor 204 processes the frequency, waveform and amplitude of the second signal SIG 2, and the appearance contour information of the above body part can be obtained.

[0039] Optionally, in the embodiment of the present application, in the above step S120 of “determining the wearing state of the wearable device 201 according to the appearance information and the distance information”, may include step S120b.

[0040] Step S120b, when the distance information and the appearance information meet the first preset state, it is determined that the wearable device 201 is in the first wearing state; when the distance information and the appearance information meet the second preset state, it is determined that the wearable device 201 is in the second wearing state; the first wearing state is that the wearable device 201 is worn on the left hand, and the second wearing state is that the wearable device 201 is worn on the right hand.

[0041] In the embodiment of the present application, when the signal transmitter 202 is directed toward the arm, the second signal SIG 2 is a reflected signal of the arm, so the waveform, amplitude and frequency of the second signal SIG 2 can reflect the shape information of the arm, and the time difference between transmitting the first signal SIG 1 and receiving the second signal SIG 2 can reflect the distance information between the arm and the wearable device 201; when the signal transmitter 202 is directed toward the back of the hand, the second signal SIG 2 is a reflected signal of the back of the hand, so the waveform, amplitude and frequency of the second signal SIG 2 can reflect the shape information of the back of the hand, and the time difference between transmitting the first signal SIG 1 and receiving the second signal SIG 2 can reflect the distance information between the back of the hand and the wearable device 201; when the signal transmitter 202 is directed toward the torso, the second signal SIG 2 is a reflected signal of the torso, so the waveform, amplitude and frequency of the second signal SIG 2 can reflect the shape contour information of the torso, and the time difference between transmitting the first signal SIG 1 and receiving the second signal SIG 2 can reflect the distance information between the torso and the wearable device 201.

[0042] Optionally, in the embodiment of the present application, step S120b is used to determine the wearing state according to whether the appearance information and the distance information are consistent with the preset state. The distance information and the appearance profile information satisfy the first preset state, including: when the second signal SIG 2 is a reflection signal of the back of the hand, the distance information is the distance from the wearable device 201 to the back of the left hand, and the appearance profile information is the appearance profile information of the back of the left hand; when the second signal SIG 2 is a reflection signal of the arm, the distance information is the distance from the wearable device 201 to the left arm, and the appearance profile information is the appearance profile information of the left arm; when the second signal SIG 2 is a reflection signal of the body, the distance information is the distance from the wearable device 201 to the left body, and the appearance profile information is the appearance profile information of the left body obtained by scanning the left body from the wearing position. The distance information and the shape contour information satisfy a second preset state, including: when the second signal SIG 2 is a reflection signal of the back of the hand, the distance information is the distance from the wearable device 201 to the back of the right hand, and the shape contour information is the shape contour information of the back of the right hand; when the second signal SIG 2 is a reflection signal of the arm, the distance information is the distance from the wearable device 201 to the right arm, and the shape contour information is the shape contour information of the right arm; when the second signal SIG 2 is a reflection signal of the torso, the distance information is the distance from the wearable device 201 to the right torso, and the shape contour information is the shape contour information of the right torso obtained by scanning the right torso from the wearing position.

[0043] In the embodiment of the present application, the first preset state and the second preset state both include appearance information and distance information. The appearance contours of the left and right backs of the hands, the left and right arms, and the left and right torsos are different, and the distances between the aforementioned body parts and the wearable device 201 are also different. Therefore, when the appearance contour information and the distance information obtained after the second signal SIG 2 is processed meet the above-mentioned specific conditions, it can be determined whether the wearer of the current wearable device 201 is the left hand or the right hand.

[0045] Step S001: obtaining a heart rate signal of the wearer through the heart rate sensor 205; and determining that the wearable device 201 is located on the arm of the wearer according to the heart rate signal.

[0046] In the embodiment of the present application, the function of step S001 is to obtain the user's heart rate signal through the heart rate sensor 205, thereby determining that the user has worn the wearable device 201, and then start the aforementioned wearing state detection method to detect the user's wearing hand, thereby saving the energy consumption of the device and making the detection more accurate.
