Description

Method for judging wearing state of wearing device and wearing device Technical field

The present invention relates to the field of electronic technologies, and in particular, to a method for determining a wearing state of a wearable device and a wearable device.

Background technique

As the functions of wearable devices become more and more perfect, wearable devices are becoming one of the indispensable electronic devices. Generally speaking, the working mode of the wearable device in the wearing state and the non-wearing state is different. For example, when the wearable device is in the wearing state, all functions of the device can be supported, and when the wearable device is in the non-wearing device, When wearing the state, some non-essential applications may be turned off to reduce the power consumption of the wearable device and extend the standby time of the device. In this scenario, it is especially important to identify whether the wearable device is worn or not. At present, the detection method adopted generally detects whether the wearable device is blocked by the object by the infrared sensor, and if the object is blocked by the object, the wearable device is considered to be currently worn. However, the infrared sensor recognizes that the wearable device is blocked by the object and cannot be equivalent to the wearable device being worn. For example, when the user puts the wearable device on other objects, it is not worn, but the infrared sensor recognizes it. If there is an object occlusion, then a wrong judgment will be made, which in turn will cause the wearable device to enter an operating mode according to the wearing state or an open/closed application error.

Summary of the invention

The present invention provides a wearing state determining method and a wearing device of a wearable device, which can improve the recognition accuracy of the wearing state of the wearable device.

The first aspect provides a method of determining a wearing state of a wearable device. When the wearable device is in the non-wearing state, whether the wearing action occurs is detected by the capacitive sensor, and if the wearing action is detected, the wearing device is switched from the non-wearing state to the wearing state, and when the wearing device is in the wearing state, the infrared light is passed through The sensor detects whether a disengagement action occurs, and if it is detected that the disengagement action occurs, the wearable device is switched from the wearing state to the non-wearing state.

If not, the capacitance sensor can be further verified to be correct, and the wearable device is currently in a wearing state; if it is in a static state , then you can recognize If the capacitance sensor detects an error, the wearable device is switched from the wearing state to the non-wearing state. That is to say, the acceleration sensor can calibrate the recognition result of the capacitance sensor, and when the capacitance sensor recognizes an error, the wearable device is switched back to the non-wearing state in time, thereby further improving the recognition accuracy of the wearing state of the wearable device.

Further, in the embodiment of the present invention, the wearing device may include two states: a wearing state and a non-wearing state, wherein the wearing state may refer to a state in which the wearing device is worn by the user, and the non-wearing state may refer to the wearing device not being worn by the user. status.

As shown in FIG. 1, the method includes:

In step S101, the wearable device is powered on.

In step S102, the processor turns on the capacitive sensor.

When the wearable device is initially powered on, the wearable device may be in a non-wearing state by default, and the non-wearing state includes turning on the capacitive sensor.

Further, when the wearable device is powered on, two scenarios may be included. The first is that the processor only turns on the capacitive sensor; the second is that the processor turns on the capacitive sensor and the infrared sensor at the same time.

It should be noted that, when the wearable device is in the non-wearing state, the processor analyzes the wearing state of the wearable device according to the data of the capacitive sensor. Therefore, in the second scenario, the processor may temporarily not use the data of the infrared sensor. The processing is performed or combined with the data of the infrared sensor to further analyze the wearing state of the wearing device.

In step S103, the processor detects whether a wearing action occurs by using the capacitive sensor, and if it is detected that the wearing action occurs, step S104 is performed; otherwise, step S103 is performed.

Capacitive sensor (English: Capacitance Sensor), is a kind of conversion of other quantities into capacitors The changes reflect the instrument. The wearing action may refer to an action that occurs when the user wears the wearing device that is not worn on a certain time or a certain period of time. When the capacitive sensor touches different materials, the detected capacitance value is different, and when the user wears the wearing device, the wearing device is usually attached to the skin for a period of time, for example, when wearing the smart watch, The smart watch will be pressed against the wrist for a moment or a period of time, and the capacitance detected close to the skin is usually very high compared to other materials. Then, it can be considered that when the processor detects that the capacitance value acquired by the capacitive sensor at a certain instant or a certain period of time is greater than a preset capacitance threshold, it can be determined that the wearing action occurs, and if the processor detects If the capacitance value obtained by the capacitive sensor is less than the preset capacitance threshold, it can be considered that the wearing action does not occur, that is, the wearable device is still in the non-wearing state.

For example, if the preset threshold of the wearable device is 60000pF, when the user performs the action of wearing the watch as shown in FIG. 3, the capacitive sensor can acquire a moment or a certain period of time when the user is close to the wrist while wearing the smart watch. The capacitance value is 60102pF, and the processor can detect that the capacitance value acquired by the capacitance sensor is 60102pF is greater than the preset capacitance threshold of 60000pF, and the processor can determine that the wearing action occurs at this time.

For another example, if the preset threshold of the wearable device is 60000pF, when the wearable device is placed on an object with a texture of iron, the capacitance value obtained by the capacitive sensor is 55000pF, and the processor can detect the obtained by the capacitive sensor. If the capacitance value of 55000 pF is less than 60000 pF of the preset capacitance threshold, the processor can determine that no wearing action has occurred at this time.

It should be noted that the setting of the capacitance threshold may be set according to an average value or a range of capacitance values of the wearable device attached to the skin detected by multiple experiments, so that it is determined according to the capacitance threshold whether the user will wear The device is attached to the skin.

Step S104, the processor switches the wearable device from the non-wearing state to the wearing state.

After the processor detects that the wearing action occurs, the wearable device can be switched from the non-wearing state to the wearing state, that is, the wearing device enters the wearing state. At this time, the processor does not need to detect whether the wearing action occurs through the capacitive sensor, so the wearing device in the wearing state can include two scenarios, the first is that the processor turns off the capacitive sensor; the second is that the processor does not turn off the capacitive sensor. However, the data of the capacitive sensor can be temporarily processed.

Specifically, the wearing state includes turning on the infrared sensor, according to the step mentioned in step S102. In the first scenario, the processor only turns on the capacitive sensor, and when the wearable device switches to the wearing state, the processor can turn on the infrared sensor, and analyze the wearing state of the wearing device according to the data of the infrared sensor; In the second scenario, the processor has turned on the capacitive sensor and the infrared sensor at the same time. When the wearable device is switched to the wearing state, the processor does not need to open the infrared sensor, but starts to process the data of the infrared sensor.

In general, when the wearable device is in the wearing state, the infrared sensor needs to be in an open state, and the capacitive sensor may be in an open state or a closed state.

In the embodiment of the present invention, in the case that the wearing device is in the wearing state, the processor may enable some applications or functions that are only supported in the wearing state, for example, the processor may enable the payment function only in the wearing state; When wearing the state, the processor can turn on the measurement function of signs such as heart rate pulse.

In step S105, the processor detects whether the disengaged state occurs by the infrared sensor. If it is detected that the disengagement action occurs, step S106 is performed; otherwise, step S105 is performed.

Infrared Ray Sensor (English: Infrared Ray Sensor) is a sensor that uses the physical properties of infrared light to measure. Infrared is also called infrared light, which has the properties of reflection, refraction, scattering, interference, absorption and so on. The stripping action may refer to an action that occurs when the user wears the wearing device from himself or at a certain time. The function of the infrared sensor is very large, and it can detect the intensity of the infrared light or detect whether there is a covering in a certain range. Therefore, according to these two characteristics of the infrared sensor, the processor detects whether or not the wearing action occurs by the infrared sensor. You can also have any of the following two ways:

Manner 1: When the processor detects that the infrared light intensity received by the infrared sensor at any time point within the second preset duration is less than a preset light intensity threshold, determining that the disconnection action occurs.

The infrared sensor can emit infrared rays. If there is an object blocking, the emitted infrared rays will be reflected back. The closer the object is to the infrared sensor, the smaller the loss when reflected back, and the reflected infrared light intensity received. On the other hand, if the obstruction is farther away from the infrared sensor, the greater the loss when reflected back, the lower the infrared intensity received back. When the user takes off the wearable device, there is usually a period of time when the wearable device is far away from the user's body. For example, when the smart watch is worn off, the smart watch will be removed from the wrist for a period of time, away from the wrist. Produce a large distance, at this time, the infrared light intensity detected by the infrared sensor is It will be small. According to the principle, the processor obtains the intensity of the infrared light received by the infrared sensor, and determines whether the infrared light intensity received at any time point within the second preset time is less than the preset light intensity threshold, and if so, Then, it can be considered that the wearable device is far away from the user's body for a second preset time period, and then the processor can confirm that the wear-out action has occurred.

For example, if the preset light intensity threshold is 50 cd (candela, light intensity unit) and the second preset time is 3 s, when the user performs the action of taking off the watch as shown in FIG. 4, the processor can acquire the infrared sensor. The intensity of the infrared light received in each of the 3s is less than 50 cd, and the processor can confirm that the stripping action has taken place.

It should be noted that the setting of the light intensity threshold may be set according to the average value or range of the light intensity data when the wearable device is detected by multiple experiments, so that the user can be determined according to the light intensity threshold. Whether to take the wearable device off the body.

Manner 2: When the processor detects that the wearable device has no obstruction within a preset distance threshold at any time point within the third preset duration by the infrared sensor, determining that the disengagement action occurs.

The infrared sensor can emit infrared rays, and if there is an object blocking, the emitted infrared rays will be reflected back, and it can be determined that an object is blocked. In this implementation, the obstruction herein may specifically refer to the user's body. When the user takes off the wearable device, there is usually a period of time when the wearable device is far away from the user's body. For example, when the smart watch is worn off, the smart watch will be removed from the wrist for a period of time, away from the wrist. A large distance is generated, at which point the infrared sensor can detect that the wearable device is unobstructed within this distance. According to this principle, the processor can detect whether there is an obstruction by using an infrared sensor, and if the processor detects that the wearable device has no obstruction within a preset distance threshold at any time point within the third preset duration by the infrared sensor, That is to say, the wearable device is away from the user's body for a predetermined period of time, and the processor can determine that the wear-out action has taken place.

For example, assuming that the preset distance threshold is 2 cm and the third preset duration is 2 s, when the user performs the action of taking off the watch as shown in FIG. 4, the processor can detect that the detected time is detected at any time within 2 s by the infrared sensor. The result is that the wearable device has no obstruction within 2 cm, so the processor can determine that the disengagement action has taken place. On the other hand, if the user does not remove the wearing device at this time, only the wearing device is shaken, the distance from the user's body is about 1cm, and the infrared sensor can detect that there is obstruction within 2cm, then the processor can Make sure that no stripping action has taken place.

It should be noted that the setting of the distance threshold may be set according to the average value or range of the distance from the body or a certain part of the body when the wearable device is detected by multiple experiments, so as to be based on the distance. The threshold can determine if the user has removed the wearable device from the body.

Step S106, the processor switches the wearable device from the wearing state to the non-wearing state.

The processor switches the wearable device from the wearing state to the non-wearing state, that is, the wearing device enters the non-wearing state. At this time, the processor does not need to detect whether the wear-off action occurs through the infrared sensor, so the wearable device in the non-wearing state may include two scenarios, the first is that the processor turns off the infrared sensor; the second is that the processor does not turn off. Infrared sensor, but the data of the infrared sensor can be temporarily processed.

Specifically, the non-wearing state includes turning on the capacitive sensor. According to the two scenarios mentioned in step S104, in the first scenario, the processor turns off the capacitive sensor when the wearing device is in the wearing state, and the wearing device switches to In the non-wearing state, the processor can turn on the capacitive sensor, and analyze the wearing state of the wearing device according to the data of the capacitive sensor; in the second scenario, the processor does not turn off the capacitive sensor when the wearing device is in the wearing state, and then wears When the device is switched to the non-wearing state, the processor does not need to turn on the capacitive sensor, but starts processing the data of the capacitive sensor.

In general, when the wearable device is in the non-wearing state, the capacitive sensor needs to be in an open state, and the infrared sensor may be in an open state or a closed state.

In the embodiment of the present invention, in the case that the wearable device is in the non-wearing state, the processor may end all applications except the application in the preset protected application set running in the wearable device, wherein the preset protection The application collection can be an application that the user or the user is accustomed to not being turned off or disabled in a non-wearing state, such as a clock, etc., while other applications that are not part of the protected application set can end. It can save the power consumption of the wearable device.

According to the description of the above steps S102 to S106, the scenarios of opening and closing of the capacitive sensor and the infrared sensor can be summarized. In the embodiment of the present invention, three scenarios may be included: in the first scenario, the capacitive sensor and the infrared sensor are simultaneously turned on at the time of power-on, and are always turned on after being turned on, but only the basis for performing data analysis is different; In the two scenarios, the wearable device turns on the capacitive sensor when the wearer is in the non-wearing state, turns off the infrared sensor, and is in the worn state. When the infrared sensor is turned on, the capacitive sensor is turned off; in the third scenario, the capacitive sensor is turned on when the device is turned on, and the device is always turned on, while the wearable device only turns on the infrared sensor when in the wearing state, and only turns off the infrared sensor when not in the worn state. Or, the infrared sensor is turned on when the device is turned on, and the device is always turned on, and the wearable device only turns on the capacitive sensor when the device is not worn, and only the capacitive sensor is turned off when the device is worn.

Optionally, after the step S104 is performed, step S107 may be further performed.

It should be noted that, in the embodiment of the present invention, there are two scenarios for the activation of the acceleration sensor. In the first scenario, the processor may turn on the acceleration sensor when the wearable device is powered on in step S102. In the second scenario, the wearing state of step S104. The acceleration sensor may be included, that is, the processor turns on the acceleration sensor when switching the wearable device from the non-wearing state to the wearing state.

Step S107: The processor detects, by the acceleration sensor, whether the wearable device is in a stationary state within a first preset time period, and if in a stationary state, performs step S106; otherwise, performs step S107.

Accelerometer (English: Accelerate Sensor), an accelerometer is a sensor that measures the acceleration force (the force acting on an object while it is accelerating). When the wearable device inevitably generates acceleration during use, such as movement, shaking, etc., the acceleration sensor can detect the acceleration, and if the wearable device is idle at a certain position, the acceleration sensor can not detect any acceleration. In this way, the processor can determine whether the wearable device is at a standstill by the acceleration sensor.

In the implementation of the present invention, the processor may detect whether the acceleration sensor acquires acceleration within a first preset duration, and if the processor detects that the acceleration sensor has acquired acceleration, the processor may determine that the acceleration is within the first preset duration. The wearable device is not in a stationary state; if the processor does not detect that the acceleration sensor has acquired acceleration, it may be determined that the wearable device is in a stationary state for the first predetermined duration. For example, if the first preset duration is 5 minutes, if the processor detects that the acceleration sensor has not acquired the acceleration for 5 consecutive minutes, it can be determined that the wearable device within the first preset duration is always in a stationary state.

It should be noted that there is no strict sequential execution sequence between step S105 and step S107, which can be performed at the same time. The two steps are only two branches after the wearable device enters the wearing state.

It can be seen that step S102 to step S107 can be an independent execution process, also It can be a cyclic execution process, and can start from any step to form a loop process as shown in FIG. 5.

In the embodiment shown in FIG. 1 , when the wearable device is in the non-wearing state, it is detected by the capacitive sensor whether the wearing action occurs, because the capacitive sensor can recognize whether the wearing device is in close contact with the user's body, and avoid occlusion by the infrared sensor. This method recognizes other physical obstructions other than the human body as the human body and causes the wearing state to be switched incorrectly; when the wearing device is in the wearing state, the infrared sensor detects whether the disengaging action occurs, because the wearable device has the wearable device after the user wears the wearing device There may be swaying, etc., and it is impossible to keep close to the body. The capacitive sensor is easy to misidentify when the wearing device is not close to the body, and the infrared sensor can recognize whether there is an obstruction in a certain distance range. That is to say, even if the wearing device is not close enough to the body, as long as the preset distance range is not exceeded, it can be considered that no disengagement action occurs, and the wearing state switching error is prevented due to the occurrence of the disengagement action of the capacitive sensor due to the swaying misidentification. On the other hand, when the wearable device is switched from the non-wearing state to the wearing state, there is a scenario in which the capacitive sensor is turned off while the infrared sensor is turned on; when the wearing state is switched to the non-wearing state, there is a scenario in which the infrared sensor is turned off and turned on at the same time. Capacitive sensor. That is, the capacitive sensor and the infrared sensor are turned on, which can reduce the power consumption of the wearable device and prolong the service life. In another aspect, the acceleration sensor further detects whether the wearable device is in a static state during the first preset time period, and can verify whether the detection of the previous capacitive sensor is correct: if the wearable device is not in a static state, it can be determined that the capacitive sensor is correctly detected, and the wearable device is It is in the wearing state; if the wearing device is in a stationary state, it can be determined that the capacitive sensor detects an error, and the processor can switch the wearing device from the wearing state to the non-wearing state. That is to say, the acceleration sensor can calibrate the recognition result of the capacitance sensor, and when the capacitance sensor recognizes an error, the wearable device is switched back to the non-wearing state in time, thereby further improving the recognition accuracy of the wearing state of the wearable device.
