Specific embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiment is only a part of the embodiments of the present invention, instead of all the embodiments.Base
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts it is all its
His embodiment, shall fall within the protection scope of the present invention.
Referring to Fig. 1, a kind of motion detection method of the embodiment of the present invention the following steps are included:
Step S1: the change information of the electrical signal of the appointed part of user's body is obtained；
Step S2: judge whether user makes required movement according to the change information of the electrical signal.
The motion detection method of the present embodiment can be applied to electronics wearable device, and the electronics wearable device can be intelligence
Wrist-watch, Intelligent bracelet or other wearable devices, the electronics wearable device have detection human skin equipped with detecting electrode
The function of the electrical signals such as voltage, impedance, the electric current on surface.
Specifically, user is after the appointed part carrying electronic wearable device of body, by the detection electricity of electronics wearable device
Pole is placed on the appointed part of user's body to obtain the change information of electrical signal.When user's appointed part is opposing stationary,
The electrical signal for the appointed part that detecting electrode detects is a stationary value.When user makes required movement, since this refers to
Fixed movement can be with the vital signs (stream of blood in such as human body of biological tissue and the related organ of the appointed part part of user
Whether dynamic, body fluid full, the cyclic activity of heart, organ mass, respiratory) variation, correspondingly cause electricity letter
Number numerical value change.Posture before restoring to act after user completes required movement, then user's appointed part is relevant
The vital signs of biological tissue and organ is by the state before being gradually restored to act.In this recovery process, detecting electrode
Detect that the numerical value of electrical signal will also be gradually restored to the numerical value before acting.Either make movement still make movement
Later, changes will occur for electrical signal, therefore can determine whether that user has according to the change information of the electrical signal of appointed part
Do not make required movement.
The appointed part of above-mentioned user's body can be wrist, thigh, shank, waist or other positions.For example, user exists
Weared on wrist electronics wearable device makes the detecting electrode of electronics wearable device be located at wrist front two sides to obtain the electricity of wrist
The change information of signal.When wrist is opposing stationary, electrical signal acquired in detecting electrode is a stationary value.When user clenches fist
When and when unclamping fist after clenching fist, the local biologic tissue of wrist can be changed with the vital signs of related organ to draw
The electrical signal for playing wrist changes.Therefore it can judge that user is according to the change information of the electrical signal of user's wrist
It is no to make movement of clenching fist.
For another example, user can make the detection of electronics wearable device after shank, thigh or waist carrying electronic wearable device
Electrode contacts to obtain the change information of the electrical signal of shank, thigh or waist with shank, thigh or waist.Work as user
Thigh, shank or when opposing stationary waist, electrical signal acquired in detecting electrode is a stationary value.When user's bending knee
And when stretching leg after bending knee, the local biologic tissue of thigh or shank can change to the vital signs of related organ
Electrical signal so as to cause thigh or shank changes；Similarly, when waist being stretched when user bends over and after bending over, waist
The electrical signal in portion can also change.Therefore can according to the change information of the electrical signal of the appointed part of user's body come
Judge whether user makes the required movement of corresponding site and make the state of required movement.
In one embodiment, above-mentioned steps S1 includes:
Step S11: the impedance of the appointed part of detection user's body, current or voltage；
Step S12: calculating the change rate of the impedance, current or voltage, obtains the change information of electrical signal.
In the present embodiment, since the impedance of human body is physical presence, human body dresses electronics there is also faint electric current
Detecting electrode in equipment is placed in the appointed part of user's body the voltage that can obtain the appointed part, therefore can be used
Impedance, electric current, voltage are as the specific electrical signal for carrying out motion detection.
Change rate is to indicate variable change speed and can intuitively reflect the parameter how variable changes, when impedance, electric current or
When voltage changes, by calculating their change rate it can be learnt that their situation of change, therefore impedance, electric current can be used
Or change information of the change rate of voltage as electrical signal.
In one embodiment, above-mentioned steps S12 includes:
Step S121: impedance, current or voltage and the time match that various time points are detected are at a curve；
Step S122: seeking the slope at any point on the curve, obtains the change information of electrical signal.
After carrying electronic wearable device is worn on human body, impedance, current or voltage can be all detected at the moment, by adopting
The numerical value of the impedance, current or voltage that collect various time points can then be fitted as dependent variable, and using the time as independent variable
The curve that one Impedance of reflection, current or voltage change over time, as shown in Figure 2.
In the curve, impedance, current or voltage change rate be impedance, current or voltage increment level off to zero when,
The limit of the quotient of the increment of impedance, the increment of current or voltage and time, the specially slope on curve.Therefore it can be used required
Change information of the slope at any point as electrical signal on the curve taken.
In one embodiment, above-mentioned steps S2 includes:
Step S21: if the slope of a curve of the impedance and time are positive value, by the slope and the first given threshold
Compare, if the slope is greater than or equal to first given threshold, determines that user makes required movement, first setting
Threshold value is positive number；Alternatively,
If the impedance slope of the electric current and the curve of time is negative value, by the slope and the second given threshold ratio
Compared with if the slope less than or equal to second given threshold, determines that user makes required movement, the second setting threshold
Value is negative；Alternatively,
If the impedance slope of the voltage and the curve of time is negative value, by the slope and third given threshold ratio
Compared with if the slope less than or equal to the third given threshold, determines that user makes required movement, the third sets threshold
Value is negative.
Specifically, during user makes required movement, the appointed part of user's body relevant to the required movement
Local biologic tissue can change to the vital signs of related organ, increase impedance, and current or voltage reduces, and be reflected in song
When on line, then the slope on the curve of impedance and time is positive, and the slope on the curve of current or voltage and time is negative.It is practical
In, local biologic tissue is critical above or equal to one to the variable quantity of the vital signs of related organ or change rate during being somebody's turn to do
Value, correspondingly, the slope of a curve of impedance and time are above or equal to specific a critical positive number, i.e. the first given threshold；
Electric current and the slope of a curve of time will be less than or equal to specific a critical negative, i.e. the second given threshold；Voltage and time
Slope of a curve will be less than or equal to another specific critical negative, i.e. third given threshold.
It clenches fist when acting for example, user is making, the impedance of user's wrist can be greater than or wait relative to the slope of time
In the first given threshold, if user does not make movement of clenching fist and only swings or be slightly curved finger, the impedance of wrist will not
Change or impedance relative to the time slope less than the first given threshold.For another example, when user is bending the knee, user's shank
Or the electric current of thigh can be less than or equal to the second given threshold relative to the slope of time, if user does not make bending knee movement,
Then the electric current of shank or thigh will not change or electric current relative to the time slope be greater than the second given threshold.For another example,
When user is bending over, the voltage of user's waist can be less than or equal to third given threshold relative to the slope of time, if user
It does not make and bends over to act, then the voltage of waist will not change or electric current is greater than second relative to the slope of time and sets
Threshold value.
In addition, restore the posture before acting after user finishes required movement, then the appointed part of user's body
Local biologic tissue can be also gradually recovered to the vital signs of related organ, correspondingly, impedance, electric current or the electricity of the appointed part
Pressure can also be restored to make the stationary value before movement.
In one embodiment, it is further comprised the steps of: before step S2
Step S-1: the displacement of the appointed part of detection user's body；
Step S-2: the displacement is compared with setting displacement threshold value；
If the displacement is less than setting displacement threshold value, S2 is thened follow the steps；Otherwise step S2 is not executed.
Specifically, when the movement being subjected to displacement except required movement occurs for the appointed part of user's body, this is specified
The local biologic tissue at position can also change to the vital signs of related organ, then the electrical signal of the appointed part also with
Change, if determining whether user makes required movement according to the variation of the electrical signal at this time will have very big error
's.Therefore, detect the appointed part of user's body be subjected to displacement and the displacement be greater than or equal to setting displacement threshold value after, nothing
How to change by the electrical signal of the appointed part and do not execute step S2 to judge whether user makes movement, thus avoid by
Other movements are mistaken for required movement, reduce False Rate, improve the accuracy of motion detection.
For example, if no matter being obtained when user makes the movement waved arm or change hands wrist etc. and wrist can be made to be subjected to displacement
The change information of electrical signal of wrist how not execute step S2, do not make about whether user makes required movement
Judgement.
In one embodiment, after step S2 comprising steps of
Step S-3: if user makes required movement, it is specified to judge that user makes according to the change information of the electrical signal
The frequency of movement.Specifically, the curve for counting the impedance and time occurs within the unit time if user makes required movement
Slope is greater than or equal to the number of the first given threshold, obtains the frequency that user makes required movement；Or the statistics electric current with
There is the number that slope is less than or equal to the second given threshold within the unit time in the curve of time, obtains user and makes specified move
The frequency of work；Or there is slope less than or equal to third given threshold within the unit time in the statistics voltage and the curve of time
Number, obtain the frequency that user makes required movement.
The motion detection method of the present embodiment is further specified dynamic to this after having determined that user is made that required movement
Quantified.Within the unit time, statistics impedance, current or voltage be more than or equal to or less than or equal to threshold value number, obtain
The frequency of required movement is made to user.A kind of vivid, intuitive operation is the curve of statistics impedance, current or voltage and time
In peak value reach the wave crest quantity of certain value.In practice, user can pass through the above method to certainly when carrying out motion exercise
The exercise motion that oneself specifies quantifies, to record the motion exercise track of oneself or to share the movement forging of oneself with friend
