Further, in the embodiment of the present invention, wearable device may include wearing state and non-wearing state two states, and wherein wearing state can refer to the state that wearable device has been worn by the user, rather than wearing state can then refer to the state that wearable device is not worn by the user.
As shown in Figure 1, which comprises
Step S101, wearable device booting.
Step S102, processor open capacitance sensor.
Wearable device can default the wearable device and be currently at non-wearing state, non-wearing state includes opening capacitance sensor when being initially powered up.
It further, may include two kinds of scenes, the first is that processor only opens capacitance sensor when wearable device is switched on；It is processor for capacitance sensor and infrared sensor while opens for second.
It should be noted that, processor is in the case where wearable device is in non-wearing state, data according to the capacitance sensor analyze the wearing state of the wearable device, therefore in above-mentioned second of scene, processor can wouldn't process the data of infrared sensor, or the wearing state for combining the data of the infrared sensor further to analyze the wearable device.
Step S103, processor detect whether that wearing, which occurs, to be acted by capacitance sensor, wearing movement occur if detecting, thens follow the steps S104；Otherwise, step S103 is executed.
Capacitance sensor (English: Capacitance Sensor) is a kind of transformation by other amounts with capacitor
The reflected instrument of variation.Wearing movement can refer to that the wearable device that do not wear is worn on a certain moment or the interior movement occurred of certain a period of time on one's body by user.Capacitance sensor is when contacting different materials, the capacitance size detected is different, and user is when wearing wearable device, usually all wearable device can be close on the skin for some time, for example, having in a flash when wearing smartwatch or smartwatch being tightly attached in wrist by a period of time, compared with contact other materials for, at this time be close to skin detection to capacitance be usually all very high.So it is considered that, when processor detects capacitance sensor when the capacitance that certain gets in a flash or in certain time period is greater than a preset capacitance threshold value, it is assured that and wearing movement has occurred, it is on the contrary, if the processor detects that the capacitance that capacitance sensor is got is less than preset capacitance threshold value, it may be considered that wearing movement does not occur, i.e., wearable device is currently still in non-wearing state.
Such as, assuming that the preset capacitance threshold value of wearable device is 60000pF, when user carries out wearing wrist-watch movement as shown in Figure 3, capacitance sensor can get user be close to when wearing smartwatch wrist certain in a flash or the capacitance of certain a period of time be 60102pF, the capacitance 60102pF that then processor can detecte that capacitance sensor is got is greater than the 60000pF's of preset capacitance threshold value, then processor can determine has occurred wearing movement at this time.
In another example, assuming that the preset capacitance threshold value of wearable device is 60000pF, when wearable device is placed on the object that one piece of quality is iron, the capacitance that capacitance sensor is got is 55000pF, the capacitance 55000pF that then processor can detecte that capacitance sensor is got is less than the 60000pF's of preset capacitance threshold value, then processor can determine, and wearing movement does not occur at this time.
It should be noted that, here the setting of capacitance threshold value can be the average value of the wearable device patch capacitance on the skin detected according to many experiments or range is set, to can determine whether user has been attached to wearable device on skin according to the capacitance threshold value.
Wearable device is switched to wearing state by non-wearing state by step S104, processor.
After processor detects, and wearing movement occurs, then wearable device can be switched into wearing state by non-wearing state, i.e. wearable device enters wearing state.Processor no longer needs to whether detect wearing movement by capacitance sensor at this time, therefore the wearable device in wearing state may include two kinds of scenes, the first is that processor closes capacitance sensor；Second is that processor does not close capacitance sensor, but can wouldn't process to the data of capacitance sensor.
Specifically, wearing state includes opening infrared sensor, according to what is mentioned in step S102
Two kinds of scenes, in the first scene, processor only opens capacitance sensor, then processor can open infrared sensor when wearable device switches to wearing state, the data according to the infrared sensor analyze the wearing state of the wearable device；In second of scene, processor opens capacitance sensor and infrared sensor simultaneously, when so wearable device switches to wearing state, processor just no longer needs to open infrared sensor, but starts to process the data of infrared sensor.
On the whole, for wearable device in wearing state, infrared sensor need to be in the open state, and capacitance sensor can be open state and be also possible to closed state.
In embodiments of the present invention, for wearable device in the case where wearing state, processor can open some application programs or function for only supporting to use under wearing state, for example, processor can open payment function only in wearing state；Only in wearing state, processor can open the measurement function of the signs such as heart rate pulse.
Step S105, processor detect whether to occur to take off to wear state, wear movement if detecting and occurring to take off, then follow the steps S106 by infrared sensor；Otherwise, step S105 is executed.
Infrared sensor (English: Infrared Ray Sensor), the sensor for being a kind of physical property using infrared ray to measure.The properties such as infrared ray is also known as infrared light, it has reflection, refraction, scatters, interferes, absorbs.It is de- to wear movement and refer to user by the wearable device of wearing from the movement winning a certain moment got off on one's body or occurring in certain a period of time.The function of infrared sensor is very more, both the intensity of infrared light had been can detecte, whether also can detecte in a certain range has shelter, therefore, according to both characteristics of infrared sensor, processor detects whether that the de- method for wearing movement, which occurs, can also any one of following two mode by infrared sensor:
Mode one: it when the infrared light intensity that processor detects that any point-in-time of the infrared sensor in the second preset duration receives is respectively less than preset Intensity threshold, determines to occur to take off and wears movement.
Infrared sensor can emit infrared ray, and when blocking if there is object, the infrared reflection of transmitting will be returned, and block that object is closer from infrared sensor, then the reflected infrared light intensity that loss when reflecting with regard to smaller, then receives is higher；Conversely, then loss when reflecting is bigger, then the reflected infrared light intensity received is lower if shelter is remoter from infrared sensor.User is when taking off wearable device, usually all there can be one section of larger distance by body of the wearable device from user for some time, such as, it is de- wear smartwatch when, smartwatch can be taken from wrist for some time, biggish distance is generated apart from wrist, at this point, the infrared light intensity that infrared sensor detects is just
It can very little.Thus principle, processor obtains the light intensity for the infrared light that infrared sensor receives, when the infrared light intensity for judging whether that any point-in-time in the second preset duration receives is respectively less than preset Intensity threshold, if it is, so it is considered that wearable device within the time of the second preset duration far from the body of user, then processor, which can be confirmed to have occurred, de- wears movement.
Such as, assuming that preset Intensity threshold is 50cd (candela, luminous intensity unit), second preset duration is 3s, when user carry out it is as shown in Figure 4 it is de- wear a wrist watch act when, the light intensity of the available infrared ray received every time in 3s to infrared sensor of processor is smaller than 50cd, then processor, which can be confirmed to have occurred to take off, wears movement.
It should be noted that, here the setting of Intensity threshold can be the average value of light intensity data when being removed according to the wearable device that many experiments detect or range is set, to can determine whether user takes wearable device from it according to the Intensity threshold.
Mode two: it when wearable device equal have no occluder in preset distance threshold described in processor detects by the infrared sensor any point-in-time in third preset duration, determines and occurs de- to wear movement.
Infrared sensor can emit infrared ray, and when blocking if there is object, the infrared reflection of transmitting will be returned, then can determine that object blocks.In this implementation, shelter here can refer specifically to the body of user.User is when taking off wearable device, usually all there can be one section of larger distance by body of the wearable device from user for some time, such as, it is de- wear smartwatch when, smartwatch can be taken from wrist for some time, biggish distance is generated apart from wrist, at this point, infrared sensor can detect wearable device in this section apart from interior have no occluder.Thus principle, processor can detect whether shelter by infrared sensor, if processor detects any point-in-time wearable device in third preset duration in preset distance threshold when equal have no occluder by infrared sensor, that is the body of wearable device separate user within the time of third preset duration, then processor, which can determine to have occurred to take off, wears movement.
Such as, assuming that preset distance threshold is 2cm, third preset duration is 2s, when user carry out it is as shown in Figure 4 it is de- wear a wrist watch act when, it is all wearable device equal have no occluder in 2cm that processor, which can detecte the result that any point-in-time in 2s detects by infrared sensor, then processor, which can determine to have occurred to take off, wears movement.It is on the contrary, if user does not take wearable device at this time, only wearable device is shaken, and is about the distance for having 1cm with a distance from user's body, infrared sensor, which can detect, shelter in 2cm, then processor, which can be determined, wears movement there is no de-.
It should be noted that, what the average value or range that the setting of distance threshold can be the distance apart from body or a certain position of body when being removed according to the wearable device that many experiments detect here was set, so that threshold value can determine whether user takes wearable device from it according to this distance.
Wearable device is switched to non-wearing state by wearing state by step S106, processor.
Wearable device is switched to non-wearing state by wearing state by processor, i.e. wearable device enters non-wearing state.Processor no longer needs to wear whether movement detects to de- by infrared sensor at this time, therefore the wearable device in non-wearing state may include two kinds of scenes, the first is that processor closes infrared sensor；It is that processor does not close infrared sensor, but can wouldn't process to the data of infrared sensor in second.
Specifically, non- wearing state includes opening capacitance sensor, according to the two kinds of scenes mentioned in step S104, in the first scene, processor has been shut off capacitance sensor when wearable device is in wearing state, when so wearable device switches to non-wearing state, processor can open capacitance sensor, and the data according to the capacitance sensor analyze the wearing state of the wearable device；In second of scene, processor is not off capacitance sensor when wearable device is in wearing state, then processor starts to process the data of capacitance sensor without being then turned on capacitance sensor when wearable device switches to non-wearing state.
On the whole, for wearable device in non-wearing state, capacitance sensor need to be in the open state, and infrared sensor can be open state and be also possible to closed state.
In embodiments of the present invention; wearable device is in the case where non-wearing state; processor can terminate all application programs in addition to the application program in preset protection pool of applications run in wearable device; wherein preset protection pool of applications can be user oneself or be accustomed to some application programs for being not turned off or disabling under non-wearing state of setting according to user; such as clock etc.; and other application programs for being not belonging to protection pool of applications can then terminate, and can save the power consumption of wearable device.
According to above-mentioned steps S102 to the description of step S106, can summarize to the scene of the opening and closing of capacitance sensor and infrared sensor.In embodiments of the present invention, may include three kinds of scenes: in the first scene, capacitance sensor and infrared sensor are opened simultaneously in booting, and it is subsequent be constantly in open state, only carry out data analysis has differentiation according to processor；In second of scene, wearable device opens capacitance sensor in non-wearing state, infrared sensor is closed, in wearing state
Shi Kaiqi infrared sensor closes capacitance sensor；In the third scene, capacitance sensor is opened when booting, and it is subsequent to be constantly in open state, and wearable device only opens infrared sensor in wearing state, and infrared sensor is simply turned off in non-wearing state, or, infrared sensor is opened when booting, and it is subsequent to be constantly in open state, and wearable device only opens capacitance sensor in non-wearing state, is simply turned off capacitance sensor in wearing state.
Optionally, after step S104 execution, step S107 can further be executed.
It should be noted that the embodiment of the present invention for acceleration transducer unlatching there are two types of scene, in the first scene, processor can open acceleration transducer when step S102 wearable device is switched on；In second of scene, the wearing state of step S104 may include opening acceleration transducer, i.e. processor has been switched on acceleration transducer when wearable device is switched to wearing state from non-wearing state.
Step S107, processor detect whether the wearable device in the first preset duration remains static by acceleration transducer, if remaining static, then follow the steps S106；Otherwise, step S107 is executed.
Acceleration transducer (English: Accelerate Sensor), acceleration transducer is the sensor that one kind can measure acceleration (acting on the power on object in accelerator when object).Wearable device will necessarily generate acceleration in the use processes such as movement, shaking, so acceleration transducer can detect acceleration, and if wearable device is to leave unused to be in static situation in a certain position, so acceleration transducer just can't detect any acceleration, and such processor can be by acceleration transducer it may determine that whether wearable device remains static out.
In the present invention is implemented, processor can detecte whether acceleration transducer gets acceleration in the first preset duration, if the processor detects that acceleration transducer gets acceleration, then processor can determine that the wearable device in the first preset duration is not at stationary state；If processor is not detected acceleration transducer and gets acceleration, it can determine that the wearable device in the first preset duration is constantly in stationary state.For example, it is assumed that the first preset duration is 5 minutes, if the processor detects that continuous 5 minutes acceleration transducers all do not get acceleration, then can determine that the wearable device in the first preset duration is constantly in stationary state.
It should be noted that do not have between step S105 and step S107 it is stringent it is successive execute sequence, may be performed simultaneously, two steps are the Liang Ge branch after wearable device enters wearing state.
It can be seen that step S102 to step S107 can be an independent implementation procedure,
It can be the process that a circulation executes, can be recycled since any step, form circulation process as shown in Figure 5.
In the embodiment shown in fig. 1, when wearable device is in non-wearing state, it detects whether that wearing movement occurs by capacitance sensor, because capacitance sensor can identify whether wearable device occurs the case where being close to user's body, avoids passing through infrared sensor identification this method of shelter and other non-human quality shelters are identified as human body and lead to wearing state handoff error；When wearable device is in wearing state, it detects whether to occur to take off by infrared sensor to wear movement, because after user wears wearable device, wearable device is possible to situations such as shaking, it can not cling to the body always, capacitance sensor, which is easy to misidentify in the case where wearable device not enough clings to the body to have occurred to take off, wears movement, and infrared sensor can identify whether certain distance range has the case where shelter, even if that is wearable device not enough clings to the body, as long as being no more than preset distance range, it can think to wear movement there is no de-, avoiding capacitance sensor, shaking misrecognition generation is de- to wear movement and leads to wearing state handoff error because wearing.It on the other hand, is to close capacitance sensor to open infrared sensor simultaneously there are a kind of scene when wearable device switches to wearing state by non-wearing state；It is to close infrared sensor to open capacitance sensor simultaneously there are a kind of scene when switching to non-wearing state by wearing state.I.e. capacitance sensor and infrared sensor rotation are opened, and this mode can reduce the power consumption of wearable device, prolong the service life.Another further aspect, further detect whether wearable device in the first preset duration remains static by acceleration transducer, before can verifying capacitance sensor detect whether it is correct: if wearable device is not at stationary state, it can so determine that capacitance sensor detection is correct, wearable device is in wearing state；If wearable device remains static, it can be determined that mistake occurs in capacitance sensor detection, wearable device can be switched to non-wearing state by wearing state by processor.That is, acceleration transducer can calibrate the recognition result of capacitance sensor, it is identified when the error occurs in capacitance sensor, wearable device is switched back into non-wearing state in time, to further increase the recognition accuracy of the wearing state of wearable device.Generally speaking, this method can act by capacitance sensor and infrared sensor to wearing respectively and take off the detection for wearing movement, determine the wearing state of wearable device, improve the recognition accuracy of the wearing state of wearable device, while reducing the power consumption of wearable device.
