Below with reference to detailed description of the invention, describe the merit of described step S120 and S140 in detail
Energy.
S120: the hand in response to a user performs a target gesture, obtains at described thumb
One first blood flow information, described target gesture is thumb upwards gesture or the downward gesture of thumb.
Wherein, described blood flow information can be such as PPG information or Doppler measurement information,
It can be obtained by corresponding sensor acquisition, such as can pass through PPG sensor acquisition
Obtain described PPG information.Described first blood flow information can be the blood that first time period is corresponding
Stream information.
Described thumb upwards gesture, namely thumbs-up gesture, as in figure 2 it is shown, work as user
When providing this gesture, its four finger gripping fist, thumb is upwards.The downward gesture of described thumb, namely
Thumbs-down gesture, as it is shown on figure 3, when user provides this gesture, its four finger gripping fist,
Thumb is downward.
S140: determine one first input information according to described first blood flow information and a reference information.
In one embodiment, described step S140 may include that
S141: determine described target gesture according to described first blood flow information and a reference information
Gesture-type;
S142: determine the described first input information that described gesture-type is corresponding.
In described step S141, determine the gesture-type of described target gesture, namely determine institute
Stating target gesture is thumb upwards gesture, or the downward gesture of thumb.
As it was noted above, described blood flow information can be such as PPG information or Doppler's survey
Amount information, will be PPG information or the feelings of Doppler measurement information to described blood flow information below
Illustrate respectively under condition.
A), in one embodiment, described first blood flow information is a PPG information, phase
Described step S141 answered is further:
S141a: determine described target according to a described PPG information and a PPG reference information
The gesture-type of gesture.
Fig. 4 is the PPG information that user performs to collect at thumb during thumb upwards gesture
Waveform diagram.Fig. 5 is the PPG that user performs to collect at thumb during the downward gesture of thumb
The waveform diagram of information.By contrast it will be seen that when user performs thumb upwards gesture,
The averaged amplitude value of the PPG information obtained is higher, and when user performs the downward gesture of thumb,
The averaged amplitude value of the PPG information obtained is relatively low.Therefore, herein described method can root
According to the averaged amplitude value of the PPG information collected at thumb, to identify that user currently performs
Be thumb upwards gesture, or the downward gesture of thumb.Wherein, a certain PPG information is flat
All range value can by the range value of all sampled points in this PPG information is done with and divided by
The quantity of sampled point calculates and determines.
Wherein, a described PPG information that is to say the PPG information of first time period, in order to
Can preferably reflect the averaged amplitude value of a PPG information, described first time period
Length can be at least a PPG cycle, i.e. more than or equal to 0.8 second;Meanwhile, if described
First time period is long, then user may successively perform thumb upwards and thumb within this time period
Pointing to lower two kinds of gestures, if be now identified according to a kind of gesture, mistake may be caused,
Therefore, described first time period can perform the duration of a kind of gesture less than or equal to user, the least
In equal to 1 second.It is to say, described first time period can between 0.8 second and 1 second,
A PPG cycle is could be arranged to for the sake of Jian Dan, such as 0.8 second.
In one embodiment, described step S141a may include that
S141a ': averaged amplitude value and a reference threshold according to a described PPG information determine
The gesture-type of described target gesture.
Wherein, described reference threshold can be a range value determined by training in advance.Ratio
As, user is performed a plurality of times described thumb upwards gesture, collects many groups at thumb
PPG information is also calculated the averaged amplitude value that a thumb upwards gesture is corresponding;Then, user
Described thumb downward gesture is performed a plurality of times, at thumb, collects many group PPG information
And it is calculated the averaged amplitude value that a downward gesture of thumb is corresponding.And then, it may be determined that described
The average width that averaged amplitude value gesture downward with described thumb corresponding to thumb upwards gesture is corresponding
A range value between angle value is as described reference threshold.
In one embodiment, described step S141a ' may further include:
S1411a ': the averaged amplitude value in response to a described PPG information is more than described reference
Threshold value, determines that described gesture-type is thumb upwards gesture.
As it was noted above, the averaged amplitude value of PPG information corresponding to thumb upwards gesture can be higher than
The averaged amplitude value of the PPG information that the downward gesture of thumb is corresponding.In this step, described hands
Gesture type or be thumb upwards gesture, or it is the downward gesture of thumb, at a described PPG
The averaged amplitude value of information is more than in the case of described reference threshold, it may be determined that described gesture class
Type is thumb upwards gesture.
It is similar to, described step S141a ' may further include:
S1412a ': the averaged amplitude value in response to a described PPG information is less than described reference
Threshold value, determines that described gesture-type is the downward gesture of thumb.
In another embodiment, described step S141a may include that
S141a ": according to averaged amplitude value and at least one reference area of a described PPG information
Between determine the gesture-type of described target gesture.
Wherein, described reference interval is that a range value is interval, and it can determine with training in advance.Ratio
As, user is performed a plurality of times described thumb upwards gesture, collects many groups at thumb
PPG information, is calculated an averaged amplitude value, then root respectively according to often organizing PPG information
The reference interval that thumb upwards gesture is corresponding is may determine that with minima according to maximum therein;
Being similar to, user is performed a plurality of times the downward gesture of described thumb, collects many at thumb
Group PPG information, is calculated an averaged amplitude value, then respectively according to often organizing PPG information
Another reference that the downward gesture of thumb is corresponding is may determine that with minima according to maximum therein
Interval.
In one embodiment, described step S141a " may include that
S1411a ": the averaged amplitude value in response to a described PPG information belongs to the first reference
Interval, determines that described gesture-type is thumb upwards gesture.
As it was noted above, the thumb that described first reference interval can be training in advance to be determined is upwards
The reference interval that gesture is corresponding, when the averaged amplitude value of the described PPG information detected
When belonging to described first interval, it may be determined that described gesture-type is thumb upwards gesture.
It is similar to, described step S141a " may include that
S1412a ": the averaged amplitude value in response to a described PPG information belongs to the second reference
Interval, determines that described gesture-type is the downward gesture of thumb.
As it was noted above, described second reference interval can be that the thumb that training in advance determines is downward
The reference interval that gesture is corresponding.
The gesture-type of described target gesture is identified by the mode using described reference interval,
Although processing complexity to be higher than the above-mentioned mode being identified according to reference threshold, but, this
The accuracy of mode is higher, and is easy to increase the gesture-type that can identify, for method in the future
Upgrading reserved space.
In described step S142, the gesture-type of described target gesture and described first input letter
Corresponding relation between breath can preset, and such as thumb upwards gesture correspondence opens order,
Thumb downward gesture correspondence shutdown command.
Except determining the gesture-type of described target gesture, and then it is corresponding to input described gesture-type
Input information outside, when described method can also further determine that the execution of described target gesture
Long, and determine the input information that different execution durations is corresponding.In one embodiment,
Described method can also include:
S150a: one the 2nd PPG information adjacent after obtaining a described PPG information;
S160a: determine the hands that described 2nd PPG information is corresponding according to described PPG reference information
Gesture type;
S170a: the gesture-type corresponding in response to described 2nd PPG information and described target hands
The gesture-type of gesture is identical, it is determined that the execution duration of described target gesture includes described first
The time that time corresponding to PPG information is corresponding with described 2nd PPG information.
Wherein, described 2nd PPG information that is to say the PPG information of the second time period.Described
Second time period can be identical with described first time period or close.
The gesture-type determined in described step S141a is it can be appreciated that be a described PPG
The gesture-type that information is corresponding.The principle that realizes of described step S160a can be with described step
S141a to realize principle identical, repeat no more.
In described step S170a, if gesture-type corresponding to described 2nd PPG information and institute
The gesture-type stating target gesture is identical, then it represents that user is in described first time period and described
Described target gesture, holding of the most described target gesture it is always maintained in the time range of two time periods
Row duration includes that time corresponding to a described PPG information is corresponding with described 2nd PPG information
Time.
It will be appreciated by those skilled in the art that in order to obtain described target gesture perform duration accurate
Value, described method is after should gathering and determine a described PPG information the most adjacent the
The gesture-type that gesture-type corresponding to two PPG information, the 3rd PPG information are corresponding ...,
Until obtaining a PPG information different from the gesture-type of described target gesture, Wo Menke
With referred to as cut-off PPG information, then from the time that a described PPG information is corresponding, extremely
Time span before this cut-off PPG information is the execution duration of described target gesture.
Therefore, in one embodiment, described method can also include:
S180a: the gesture-type corresponding in response to described 2nd PPG information and described target hands
The gesture-type of gesture is different, it is determined that the execution duration of described target gesture is equal to described first
The time that PPG information is corresponding.
If it is to say, described 2nd PPG information is exactly described cut-off PPG information, then
Described target gesture perform duration the most just time described in time corresponding to a PPG information.
In order to be further illustrated, it is referred to the PPG waveform shown in Fig. 6.Such as Fig. 6
Shown in, it is assumed that experiment first obtains the PPG information of C1 time period, according to its average amplitude
Value determines that gesture-type corresponding for C1 is thumb upwards gesture;Then the C2 time period is obtained
PPG information, determines after calculation process that the gesture-type of its correspondence is also thumb upwards gesture, because of
This needs to further determine that the gesture-type that the C3 time period is corresponding;Then the C3 time period is obtained
PPG information, determine after calculation process the gesture-type of its correspondence also for thumb upwards gesture,
It is thus desirable to further determine that gesture-type corresponding to C4 time period;Then the C4 time is obtained
The PPG information of section, determines after calculation process that the gesture-type of its correspondence is the downward gesture of thumb,
It is thus determined that the time that during execution of described thumb upwards gesture, a length of C1, C2, C3 are corresponding it
With.
By above-mentioned process, described method can finally give the execution duration of described target gesture,
And described execution duration can corresponding different input information.Therefore, in one embodiment,
Described method can also include:
S190a: determine described target gesture performs the one second input information that duration is corresponding.
Wherein, the correspondence performed between duration and described second input information of described target gesture
Relation can preset, and such as its corresponding relation can be shown in Table 1 below.With in table 1
As a example by the first row record, when target gesture be thumb upwards, and perform duration less than 1.5 seconds time,
Described second input information can be to open order, such as turns on TV;As a example by second row record,
When target gesture be thumb upwards, and perform duration more than 2 seconds time, described second input information
Can be switching command forward, such as by television channel towards the direction less than current frequency channel number
Switching.
Table 1
Target gesture | Perform duration | Second input information |
Thumb is upwards | Less than 1.5 seconds | Open |
Thumb is upwards | More than 2 seconds | Switch forward |
Thumb is downward | Less than 1.5 seconds | Close |

In addition to the gesture-type determining described target gesture and execution duration, described method is also
May determine that described target gesture performs number of times corresponding different input information.Real in one
Executing in mode, described method can also include:
S200a: one the 2nd PPG information adjacent after obtaining a described PPG information;
S210a: determine the hands that described 2nd PPG information is corresponding according to described PPG reference information
Gesture type;
S220a: the gesture-type corresponding in response to described 2nd PPG information and described target hands
The gesture-type of gesture is different, it is determined that the execution number of times increase of described target gesture is once.
To realize principle with described step S150a identical, no for the principle that realizes of described step S200a
Repeat again.
To realize principle with described step S160a identical, no for the principle that realizes of described step S210a
Repeat again.
In described step S220a, the execution number of times of described target gesture can have one initially
Value, this initial value can be 0.In this step, described method can gather and determine described
Gesture-type corresponding to the 2nd PPG information the most adjacent after one PPG information, the 3rd PPG
The gesture-type that information is corresponding ..., until obtaining the gesture-type of and described target gesture
Different PPG information, we can referred to as end PPG information, then from a described PPG
Time corresponding to information rises, in the time before this cut-off PPG information, and described user one
Directly performing same gesture, and the moment before described cut-off PPG information just completes one
Secondary described target gesture.Therefore, in described step S220a, if described 2nd PPG
Gesture-type corresponding to information is different from the gesture-type of described target gesture, then it represents that described use
Family completes the most described target gesture, may thereby determine that the execution number of times of described target gesture
Increasing once, the execution of the most described target gesture is this time become 1 from zero.
If it addition, gesture-type corresponding to described 2nd PPG information and described target gesture
Gesture-type is identical, then it represents that within the time that described 2nd PPG information is corresponding, user is still
So performing described target gesture.Thus, described method can also include:
S230a: the gesture-type corresponding in response to described 2nd PPG information and described target hands
The gesture-type of gesture is identical, then one the 3rd PPG adjacent after obtaining described 2nd PPG information
Information;
S240a: determine the hands that described 3rd PPG information is corresponding according to described PPG reference information
Gesture type;
S250a: the gesture-type corresponding in response to described 3rd PPG information and described target hands
The gesture-type of gesture is different, it is determined that the execution number of times increase of described target gesture is once.
It is to say, in gesture-type corresponding to described 2nd PPG information and described target gesture
Gesture-type identical in the case of, need to determine whether that described 3rd PPG information is corresponding
Gesture-type.If the gesture-type that described 3rd PPG information is corresponding and described target hands
The gesture-type of gesture is different, then it represents that user completes the most described target gesture, thus described mesh
The execution number of times increase of mark gesture is once;Whereas if described 3rd PPG information is corresponding
Gesture-type is the most identical with the gesture-type of described target gesture, then need to determine whether described
The gesture-type that the 4th PPG information after 3rd PPG information is corresponding, the like, directly
To finding a PPG information different from the gesture-type of described target gesture, i.e. end PPG
Information, the execution number of times of the most described target gesture is become 1 from zero.
It is similar to, after described cut-off PPG information, when a PPG information occurs again
When gesture-type is identical with the gesture-type of described target gesture, can be with this PPG information of labelling
For a new PPG information, then repeat the above steps, find a new cut-off PPG
Information, the execution number of times of the most described target gesture increases once again, is i.e. become 2 from 1.
The like, described method can be according to user's request, and in obtaining one period of scheduled time, user holds
The total degree of the described target gesture of row, the execution number of times of the described target gesture the most finally determined.
In order to be further illustrated the execution number of times how determining described target gesture, can be still
Old with reference to the PPG waveform shown in Fig. 6.As shown in Figure 6, it is assumed that user needs to obtain C1~C6
The execution number of times of thumb upwards gesture is performed in during this period of time.Then as it was noted above, work as and determine
When gesture-type corresponding for C4 is thumb downward gesture, determine holding of described thumb upwards gesture
Places number increase once, is i.e. become 1 from 0;Then proceed to determine the gesture-type that C5 is corresponding,
Find that its gesture-type is thumb upwards gesture;Then, gesture corresponding to C6 is further determined that
Type, finds that its gesture-type is the downward gesture of thumb, so that it is determined that described thumb upwards gesture
Execution number of times increase once, i.e. become 2 from 1, and finally determine described thumb upwards gesture
Execution number of times be 2.
By above-mentioned process, described method can finally give the execution number of times of described target gesture,
And described execution number of times can corresponding different input information.Therefore, in one embodiment,
Described method can also include:
S260a: determine described target gesture performs one the 3rd input information that number of times is corresponding.
Wherein, the correspondence performed between number of times and described 3rd input information of described target gesture
Relation can preset, and such as its corresponding relation can be shown in Table 2 below.With in table 2
As a example by the first row record, when target gesture be thumb upwards, and perform number of times when being 1, described
3rd input information can be to open order, such as turns on TV;As a example by second row record, when
Target gesture be thumb upwards, and perform number of times when being 2, described 3rd input information can be
Volume increases order.
Table 2
Target gesture | Perform number of times | 3rd input information |
Thumb is upwards | 1 | Open |
Thumb is upwards | 2 | Volume increases |
Thumb is downward | 1 | Close |
Thumb is downward | 2 | Volume reduces |
Except as shown in table 2, the 3rd that the execution number of times of described target gesture is corresponding inputs information
Can also be determined by after Wearable calculation process voluntarily, such as, user goes back home evening
In the intelligent electric lamp that controlled in family by thumb upwards gesture open, often perform a thumb upwards
Gesture turns on an electric light;Then, when user prepares in bed, and it passes through the downward gesture of thumb
Control electric light to close, often perform a downward gesture of thumb and close an electric light.Thus, described
Described user can be performed the number of times of thumb upwards gesture as a reference value by method, then,
Judge that user performs the number of times of the downward gesture of thumb whether less than this reference value, if less than this ginseng
Examine value, then show that the electric light having is not turned off, and then can input to the most pent electric light
One flash command, electric light starts to flash 5 seconds, to remind user to close this electric light.

Inventor finds in the experiment shown in Fig. 7 and Fig. 8: when user performs thumb to left-hand seat
During gesture, as it is shown in fig. 7, the Doppler frequency shift of frequency domain information corresponding to the LDF information that obtains
Measure less;And when user performs the downward gesture of thumb, as shown in Figure 8, the LDF obtained
The Doppler frequency shift amount of the frequency domain information that information is corresponding is bigger.Therefore, herein described method can
With the Doppler frequency shift amount of the frequency domain information corresponding according to the LDF information collected at thumb,
It is thumb upwards gesture with identify that user currently performs, or the downward gesture of thumb.
In one embodiment, described step S1412b may include that
S1412b ': determine described target gesture according to described Doppler frequency shift amount and a reference threshold
Gesture-type.
Wherein, described reference threshold can be a Doppler frequency shift determined by training in advance
Amount.Such as, user is performed a plurality of times described thumb upwards gesture, collects at thumb
Many group LDF information, calculate corresponding Doppler frequency shift amount, so after carrying out frequency domain conversion respectively
The average Doppler frequency shift amount that its meansigma methods of rear calculating is corresponding to obtain a thumb upwards gesture;So
After, user is performed a plurality of times the downward gesture of described thumb, collects many groups at thumb
LDF information, calculates corresponding Doppler frequency shift amount, then calculates after carrying out frequency domain conversion respectively
The average Doppler frequency shift amount that its meansigma methods is corresponding to obtain a downward gesture of thumb.And then, can

The accuracy of mode is higher, and is easy to increase the gesture-type that can identify, for method in the future
Upgrading reserved space.
In described step S142, the gesture-type of described target gesture and described first input letter
Corresponding relation between breath can preset, and such as thumb upwards gesture correspondence opens order,
Thumb downward gesture correspondence shutdown command.
Except determining the gesture-type of described target gesture, and then it is corresponding to input described gesture-type

The gesture-type that breath is corresponding.The principle that realizes of described step S160b can be with described step
S140b to realize principle identical, repeat no more.
In described step S170b, if the gesture class that described second Doppler measurement information is corresponding
Type is identical with the gesture-type of described target gesture, then it represents that user in described first time period and
Described target gesture, the most described target hands it is always maintained in the time range of described second time period
The duration that performs of gesture includes the time and described second that described first Doppler measurement information is corresponding
The time that Doppler measurement information is corresponding.

Gesture-type corresponding to the second Doppler measurement information, Tridoppler metrical information corresponding
Gesture-type ..., until obtain one different from the gesture-type of described target gesture how general
Strangling metrical information, we can referred to as end Doppler measurement information, then from described more than first
Time corresponding to general Le metrical information rises, and the time before this cut-off Doppler measurement information is long
Degree is the execution duration of described target gesture.
Therefore, in one embodiment, described method can also include:
S180b: in response to gesture-type corresponding to described second Doppler measurement information with described
The gesture-type of target gesture is different, it is determined that the execution duration of described target gesture is equal to described
The time that first Doppler measurement information is corresponding.
If surveyed it is to say, described second Doppler measurement information is exactly described cut-off Doppler
Amount information, the execution duration of the most described target gesture is the most just described first Doppler measurement letter
The time that breath is corresponding.
In order to be further illustrated, it is referred to the LDF waveform shown in Figure 10 and correspondence thereof

Information, is converted to frequency domain information corresponding below dotted line by frequency domain, and then how general according to it
Strangle frequency shift amount and determine that gesture-type corresponding for C1 is thumb upwards gesture;When then obtaining C2
Between the LDF information of section, determine the gesture-type of its correspondence after calculation process also for thumb upwards
Gesture, it is therefore desirable to further determine that gesture-type corresponding to C3 time period;Then C3 is obtained
The LDF information of time period, determine after calculation process the gesture-type of its correspondence also for thumb to
Upper gesture, it is therefore desirable to further determine that gesture-type corresponding to C4 time period;Then obtain
The LDF information of C4 time period, determine after calculation process the gesture-type of its correspondence be thumb to
Lower gesture, it is thus determined that a length of C1, C2, C3 are corresponding during the execution of described thumb upwards gesture
Time sum.

S220b: in response to gesture-type corresponding to described second Doppler measurement information with described
The gesture-type of target gesture is different, it is determined that the execution number of times increase of described target gesture is once.
To realize principle with described step S150b identical, no for the principle that realizes of described step S200b
Repeat again.
To realize principle with described step S160b identical, no for the principle that realizes of described step S210b
Repeat again.
In described step S220b, the execution number of times of described target gesture can have one initially
Value, this initial value can be 0.In this step, described method can gather and determine described
The gesture that the second Doppler measurement information the most adjacent after one Doppler measurement information is corresponding
The gesture-type that type, Tridoppler metrical information are corresponding ..., until obtaining one and institute
Stating the Doppler measurement information that the gesture-type of target gesture is different, we can referred to as end
Doppler measurement information, then from the time that described first Doppler measurement information is corresponding, to being somebody's turn to do
In time before cut-off Doppler measurement information, described user is performing same gesture always,
And the moment before described cut-off Doppler measurement information just completes the most described target hands
Gesture.Therefore, in described step S220b, if described second Doppler measurement information is corresponding
Gesture-type different from the gesture-type of described target gesture, then it represents that described user completes
The most described target gesture, may thereby determine that the execution number of times increase of described target gesture once,
The execution of the most described target gesture is this time become 1 from zero.
If it addition, gesture-type corresponding to described second Doppler measurement information and described target
The gesture-type of gesture is identical, then it represents that in the time that described second Doppler measurement information is corresponding
In, user is still performing described target gesture.Thus, described method can also include:

It is to say, at gesture-type corresponding to described second Doppler measurement information and described mesh
Mark gesture gesture-type identical in the case of, need to determine whether that described Tridoppler is surveyed
The gesture-type that amount information is corresponding.If the gesture class that described Tridoppler metrical information is corresponding
Type is different from the gesture-type of described target gesture, then it represents that user completes the most described target hands
Gesture, thus the execution number of times increase of described target gesture is once;Whereas if described more than the 3rd
Gesture-type corresponding to general Le metrical information is the most identical, then with the gesture-type of described target gesture
Need the 4th Doppler measurement letter determined whether after described Tridoppler metrical information
The gesture-type that breath is corresponding, the like, until finding the gesture of and described target gesture
Different types of Doppler measurement information, i.e. cut-off Doppler measurement information, the most described target
The execution number of times of gesture is become 1 from zero.
It is similar to, after described cut-off Doppler measurement information, when a Doppler occurs again
When the gesture-type of metrical information is identical with the gesture-type of described target gesture, can be somebody's turn to do with labelling
Doppler measurement information is the first new Doppler measurement information, then repeat the above steps, looks for
To a new cut-off Doppler measurement information, the execution number of times of the most described target gesture is again
Increase once, i.e. become 2 from 1.The like, described method can according to user's request,
Obtain user in one period of scheduled time and perform the total degree of described target gesture.
In order to further explain how to determine the execution number of times of described target gesture, can still join
Examine the LDF waveform shown in Figure 10 and the frequency domain information of correspondence thereof.As shown in Figure 10, it is assumed that
User needs to obtain C1~C6 and performs the execution number of times of thumb upwards gesture in during this period of time.Then
As it was noted above, when determining that gesture-type corresponding for C4 is the downward gesture of thumb, determine institute
State the execution number of times increase of thumb upwards gesture once, i.e. become 1 from 0;Then proceed to determine
The gesture-type that C5 is corresponding, finds that its gesture-type is thumb upwards gesture;Then, one is entered
Step determines gesture-type corresponding to C6, finds that its gesture-type is the downward gesture of thumb, thus
Determine the execution number of times increase of described thumb upwards gesture once, i.e. become 2 from 1, and finally
The execution number of times determining described thumb upwards gesture is 2.
By above-mentioned process, described method can finally give the execution number of times of described target gesture,
And described execution number of times can corresponding different input information.Therefore, in one embodiment,
Described method can also include:
S260b: determine described target gesture performs one the 3rd input information that number of times is corresponding.
Wherein, the correspondence performed between number of times and described 3rd input information of described target gesture
