Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, some embodiments of the present invention are described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The first embodiment of the invention relates to a wearing quality detection method, which is applied to wearable equipment, such as a smart bracelet, a smart headset, a smart watch and the like. Fig. 1 shows a specific flowchart of the wearing quality detection method.

Step 101, detecting whether the wearable device is in contact with the skin of a human body. If yes, go to step 102; if not, the process is ended directly.

Specifically speaking, when the wearable equipment is normally worn by a human body, a certain side of the wearable equipment can be in contact with the skin of the human body, and the touch detection module is arranged on the side, in contact with the skin of the human body, of the wearable equipment so as to detect whether the skin of the human body is in contact with the wearable equipment.

Step 102, identifying contact parameters corresponding to the contact.

Specifically, when the wearable device is judged to be in contact with the skin of the human body, the contact is subjected to recognition analysis to obtain contact parameters corresponding to the contact. The contact parameter may be the number of contact points, the location of the contact points, etc.

And 103, matching the identified contact parameters with preset contact parameters to judge the wearing quality of the wearable device.

Specifically, information of contact parameters related to wearing quality is preset in the wearable device, different contact parameters correspond to different wearing qualities, and the wearing quality of the wearable device is judged according to the matching degree of the identified contact parameters and the preset information of the contact parameters.

Compared with the prior art, the embodiment matches the contact parameter corresponding to the identified contact point between the wearable device and the human skin with the preset contact parameter, so that the wearing quality of the wearable device is judged, the user can be provided with a prompt of the better position of the wearable device through the wearing quality, and the accuracy of the human body related parameters measured by the wearable device is guaranteed and improved.

The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, which are all within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.

The second embodiment of the present invention relates to a method for detecting wearing quality, which is a refinement of the first embodiment, and mainly comprises the following steps: in this embodiment, for step 103: the identified contact parameters are matched with the preset contact parameters to determine the wearing quality of the wearable device, which is described in detail.

In this embodiment, the contact parameters include the number of contact points, and the relationship between the wearing quality and the number of contact points is shown in table 1 below:

TABLE 1

The number of the contact points does not reach the first preset number	First level of wearing quality
		The number of the contact points reaches a first preset number	Second level of wearing quality

A specific flow of the wearing quality detection method of the present embodiment is shown in fig. 2.

Step 201 and step 202 correspond to step 101 and step 102 substantially the same, and are not described herein again; the difference is that, in this embodiment, step 203: matching the identified contact parameters with preset contact parameters to judge the wearing quality of the wearable device, specifically comprising:

sub-step 2031 of determining whether the number of the identified contact points reaches a first preset number. If yes, go to substep 2032; if not, then sub-step 2033 is entered.

Specifically, the number of contact points can be acquired by arranging the multi-touch sensor on the side, in contact with the skin of a human body, of the wearable device, different contact points correspond to different wearing qualities, and the wearing quality is higher as the number of the contact points is larger.

For example, in a wearable device for measuring heart rate based on photoplethysmography, for a measurement part (such as a finger tip and a wrist) with good blood flow perfusion, the larger the contact surface between the surface of the light emitter and the surface of a human body is (the more the number of contact points is), the stronger the signal received by the light receiver is, and the higher the wearing quality is.

It should be noted that the first predetermined number may be determined by the function and structure of the wearable device, and different wearable devices may require different numbers of contacts. Some wearable devices can work only by contacting with the skin of a human body at multiple points, such as intelligent electric massagers attached to the surface of the skin of the human body; while some wearable devices require only a few points of contact with the skin of the human body, such as a smart band or heart rate belt for measuring heart rate.

Substep 2032, determining that the wearable device is at a second level of wearing quality;

sub-step 2033 of determining that the wearable device is at a first level of wearing quality.

Specifically, when the number of the identified contact points reaches a first preset number, it is determined that the wearable device is in the second-level wearing quality; otherwise, the wearable device is judged to be in the first level of wearing quality. According to the judgment method, the second-level wearing quality is superior to the first-level wearing quality; namely, in the wearing process of the wearable device, the accuracy of the human body parameter measured under the second level wearing quality is higher than that of the first level wearing quality.

In the present embodiment, the wearing quality is determined by the number of contact points, but the present invention is not limited to this.

Compared with the first embodiment, the present embodiment introduces a specific implementation method for determining the wearing quality, and the wearing quality is determined by the number of contact points.

In the present embodiment, the relationship between the wearing quality and the number of contact points is shown in table 2 below:

and a substep 3032 of determining whether the number of identified contact points reaches a second predetermined number. If yes, go to substep 3033; if not, go to substep 3034.

Specifically, after the number of the identified contact points is judged to reach a first preset number, the number of the contact points is further judged; judging whether the number of the identified contact points reaches a second preset number or not so as to further refine the wearing quality corresponding to the number of the contact points; wherein the second preset number is greater than the first preset number.

Sub-step 3033, determining that the wearable device is at a third level of wearing quality.

Specifically, when it is determined that the number of the identified contact points reaches the second preset number, the wearable device is considered to be in the third-level wearing quality, and the third-level wearing quality is higher than the second-level wearing quality.

Compared with the second embodiment, the present embodiment further determines the number of contact points, and details the wearing quality level.

The fourth embodiment of the present invention relates to a wearing quality detection method, and the present embodiment is an improvement on the basis of the third embodiment, and the main improvement is that: the contact parameter types are increased, and the wearing quality is refined so as to further judge the wearing quality.

In this embodiment, the contact parameters further include the contact point position, and the relationship between the wearing quality and the number of contact points and the contact position is shown in table 3 below:

TABLE 3

Fig. 4 shows a specific flowchart of the wearing quality detection method according to this embodiment.

Step 401 and step 402 are substantially the same as step 301 and step 302, sub-step 4031 and sub-step 4032 are substantially the same as sub-step 3031 and sub-step 3032, and sub-step 4035 to sub-step 4037 are substantially the same as sub-step 3033 to sub-step 3035, and are not described herein again; the difference is that in this embodiment, sub-step 4033 and sub-step 4034 are added, and the following is specifically explained:

and a substep 4033 of determining whether the contact position of the identified contact point matches the contact position of the predetermined contact point. If yes, go to substep 4034; if not, then substep 4036 is entered.

Specifically, the contact parameters of the identified contact points include the contact positions, that is, the contact parameters substantially include the contact position of each contact point, and the accuracy of the anthropometric parameters obtained by the contact points at different contact positions is different; and judging whether the contact position of the identified contact point is matched with the contact position of the preset contact point, if so, entering the substep 4034, otherwise, entering the substep 4036, and judging that the wearable device is in the second-level wearing quality.

In this embodiment, the preset contact points may be key contact points of the wearable device, and the first preset number is the number of the key contact points; judging whether the contact position of the identified contact point is matched with the contact position of a preset contact point, namely, acquiring the number of key contact points in the identified contact point, and judging whether the number of the key contact points exceeds a first preset number; for example, 3 preset contact points are respectively represented by x2, x3 and x4, 6 identified contact points are provided, and when all the preset contact points are included in the identified 6 contact points (for example, x1, x2, x3, x4, x7 and x8), the two are matched; when all the preset contact points are not included in the identified 6 contact points (for example, x1, x2, x3, x5, x6, x9), it is indicated that the two are matched. The contact point position of the wearable device and the human skin is matched with the preset contact point position, so that whether the contact point of the wearable device and the human skin is a key contact point or not and the number of the key contact points in the contact point can be known.

For example: the wearable device for measuring the heart rate based on the photoplethysmography has the advantages that the measurement part is the inner side of an ear, blood perfusion in a part of the inner side of the ear is more, and a detection signal provided for the wearable device is more accurate; the other partial area has less blood perfusion, and the detection signal which can be provided to the wearable device is relatively poor. Accordingly, the contact area of the wearable device comprises a first area corresponding to a higher perfusion of blood and a second area corresponding to a lower perfusion of blood; m preset contact points in the first area are key contact points. Identifying L contact points when the wearable device is worn; if the L contact points include the M preset contact points, which indicates that M key contact points in the wearable device are all in contact with the human body, it is determined that the wearable device is in the fourth-level wearing quality. The M contact points are the above contact points, and the value of M is set according to the detection requirements of different types of wearable devices, which is not limited in this embodiment.

Specifically, when the number of key contact points in the identified contact points reaches a first preset number, it is indicated that the contact positions of the identified contact points are matched with the contact positions of the preset contact points, and it is determined that the wearable device is in the fourth-level wearing quality.

Fig. 7 shows a specific flow of the wearing quality detection method according to this embodiment.

Wherein, steps 701 and 702 correspond to

steps

101 and 102 substantially the same, and are not described herein again; the difference is that, in this embodiment, step 703: matching the identified contact parameters with preset contact parameters to judge the wearing quality of the wearable device, specifically comprising:

In this embodiment, the relationship between the wearing quality and the number and positions of the contact points is shown in table 7 below:

TABLE 7

A specific flow of the wearing quality detection method of the present embodiment is shown in fig. 8.

Wherein, steps 801 and 802 correspond to

steps

701 and 702 substantially identically, sub-step 8031 corresponds to sub-step 7031 substantially identically, sub-step 8034 and sub-step 8035 correspond to sub-steps 7032 and 7033 substantially identically, and are not repeated herein; the difference is that in this embodiment, a substep 8032 and a substep 8033 are added, and the specific explanation is as follows:

sub-step 8032, determining whether the number of the identified contact points reaches a third predetermined number. If yes, go to substep 8033; if not, go to substep 8034.

Specifically, a touch detection module is arranged on one side, which is in contact with the skin of a human body, of the wearable device to acquire the number of contact points, a third preset number is set in the wearable device, and when the contact position of the identified contact point is judged to be matched with the contact position of the preset contact point, the number of key contact points in the identified contact point reaches the first preset number, and at the moment, the number of the identified contact points is compared with the third preset number; wherein the third preset number may be the same as the second preset number.

In practice, in order to ensure the accuracy of the human-related parameters measured by the wearable device in a severe environment (such as a severe exercise of the user), the wearing quality of the wearable device is more demanding. For some wearable devices with only 1 to 2 key contact points, except that the contact points of human skin and the wearable device are required to include all key contact points, the number of the contact points also needs to reach a third preset number so as to improve the wearing quality of the wearable device, so that the key contact points of the wearable device can still be in contact with the human body under a severe environment (for example, the wearable device is loosened due to violent movement), and the accuracy of measuring human body data is ensured. When the number of the contact points reaches a third preset number, the sub-step 8033 is entered, otherwise, it is determined that the wearable device is in the fourth level wearing quality. Wherein the third predetermined number exceeds the number of predetermined contact points. .

For example, wearable equipment is the earphone, because the earphone is easily not hard up in the running process, so need guarantee higher wearing quality in the wearing process to guarantee the accuracy of heart rate measurement in the running process. Therefore, in the running process, besides ensuring that the wearing position of the earphone is better, the earphone is ensured to be in contact with the ear in the largest area, namely, key contact points are ensured to be contained in contact points of the human body and the earphone, and simultaneously, the human body and the earphone are required to contain as many contact points as possible when being in contact.

Sub-step 8033, determine that the wearable device is at a fifth level of wearing quality.

Specifically, when the number of the identified contact points reaches a third preset number, it is determined that the wearable device is at a fifth level wearing quality.

Compared with the seventh embodiment, in the embodiment, when the identified contact points include the key contact points with the first preset number, the number of the contact points is judged, so that the wearing quality is further refined; the more the number of the contact points is, the higher the wearing quality is, and the accuracy of the human body related parameters measured by the wearable equipment in a severe environment is ensured to a certain extent.

The ninth embodiment of the present invention relates to a wearing quality detection method, and the present embodiment is an improvement on the basis of the first embodiment, and the main improvement is that: the judgment of the wearing tightness is increased.

In this embodiment, a specific flowchart of the wearing quality detection method is shown in fig. 9.

Step 901 corresponds to step 101 substantially identically, and step 905 and step 906 correspond to step 102 and step 103 substantially identically and are not repeated herein; the difference is that in this embodiment, steps 902 to 904 are added, and the following is specifically explained:

and step 902, detecting a contact pressure corresponding to the contact.

Specifically, a contact pressure sensor is arranged in a contact area between the wearable device and the human body, and when the wearable device is worn, human skin at the contact point exerts a force on the wearable device (i.e., the contact area), so that the contact pressure sensor can acquire the contact pressure of the contact area.

Step 903, judging whether the contact pressure reaches a preset pressure threshold value. If yes, go to step 904; if not, go to step 905.

Specifically, when the wearable device is worn, in addition to the number and the positions of the contact points, the measurement of the human-related parameters is influenced, and the wearing tightness also influences the measurement of the human-related parameters.

In practice, the preset threshold is obtained by: in the test stage, pressure is applied between the wearable device and the skin of the human body in an increasing mode, the human body related parameters can be measured, the corresponding pressure value is changed from the state that the human body related parameters can be measured to the state that the human body related parameters can not be measured or the state that the human body related parameters are measured abnormally, and the pressure value at the moment is a preset threshold value.

For example, a bracelet for measuring a heart rate based on a photoplethysmography presses a light emitter of the bracelet on the skin in a continuously pressurizing manner, and a corresponding pressure value when a resting heart rate is changed into an abnormal heart rate is the preset threshold value. The abnormal heart rate can be a non-resting heart rate or a non-human body normal heart rate.

Step 904, determining that the wearable device is at a lowest level of wearing quality.

Specifically, when the contact pressure between the wearable device and the skin of the human body reaches a preset threshold value, it is determined that the wearable device is at the lowest level of wearing quality, at this time, the wearable device cannot measure the relevant parameters of the human body or the measured relevant parameters of the human body are abnormal, and the accuracy of the obtained relevant parameters of the human body is very low; wherein the lowest level of wearing quality is lower than the first level of wearing quality.

Compared with the first embodiment, the method and the device have the advantages that the tightness of the wearable device with the requirement on the wearing tightness is judged, and the accuracy of the acquired human body related parameters is guaranteed.
