Detailed description of the invention

Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the application is made the most in detail Explanation.Following example are used for illustrating the application, but are not limited to scope of the present application.

It will be appreciated by those skilled in the art that in embodiments herein, the sequence number of following each step Size be not meant to the priority of execution sequence, the execution sequence of each step should with its function and Internal logic determine, and the implementation process of the embodiment of the present application should not constituted any restriction.

Inventor finds in research process, if the hand of user performs different gestures, meeting There is significantly change in the blood flow information causing hand.Based on this, obtain according to sensor detection Blood flow information then can identify the gesture of user, and then may determine that corresponding defeated of corresponding gesture Enter information.Wherein, described blood flow information can be PPG (photoplethysmography, Photoplethysmographic) information, or can also is that Doppler measurement information, such as LDF (Laser Doppler Flowmetry, laser-Doppler flow velocity) information.

Fig. 1 is to input information described in one embodiment of the application to determine the flow chart of method, described Method can determine realization on equipment in such as one input information.As it is shown in figure 1, described method Including:

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；

S140: determine one first input information according to described first blood flow information and a reference information.

Method described in the embodiment of the present application, the hand in response to a user performs a target gesture, At described thumb obtain one first blood flow information, described target gesture be thumb upwards gesture or The downward gesture of thumb, then may determine that one according to described first blood flow information and a reference information First input information.Thus provide a kind of based on user's gesture, determine defeated according to blood flow information The method entering information, described method is effectively increased the input energy of the electronic equipments such as Wearable Power.

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.

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
			Thumb is downward	More than 2 seconds	Switch backward

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.

B), in another embodiment, described first blood flow information is the first Doppler measurement Information, described Doppler measurement information can be such as LDF (laser Doppler shift), LDV (Laser Doppler Velocimetry, LDV), supersonic Doppler frequency displacement Deng, it includes a series of Envelop waves signal, it is carried out such as fast Fourier transform permissible Obtaining the frequency-region signal of correspondence, the Doppler frequency shift amount in described frequency-region signal is proportional to Hemodynamic environment Degree.Thus when the range value of corresponding PPG information is the lowest, show that blood flow rate increases, Doppler frequency shift amount in the most described frequency-region signal is the biggest；Amplitude when corresponding PPG information When being worth the highest, showing that blood flow rate reduces, the Doppler frequency shift amount in the most described frequency-region signal is more Little.

Corresponding described step S141 is further:

S141b: determine according to described first Doppler measurement information and Doppler's reference information The gesture-type of described target gesture.

First as a example by frequency domain information waveform shown in solid in Fig. 9, when calculating its Doppler frequency shift amount Time, it is first determined the frequency that in the frequency values that its energy is the highest, i.e. figure, A point is corresponding, then Determine the energy intensity of this A point respective frequencies, and then determine 3dB's lower than this energy intensity The frequency that in the frequency that energy intensity is corresponding, i.e. figure, B point is corresponding, then calculates B point corresponding Frequency and the difference of A point respective frequencies, be frequency domain information waveform shown in solid in Fig. 9 Doppler frequency shift amount, i.e. f1 in Fig. 9.It is similar to, frequency described in dotted line in Fig. 9 can be obtained The Doppler frequency shift amount of domain information waveform is f2 in figure.Further, it can be seen in figure 9 that f2 More than f1.It addition, the calculating of Doppler frequency shift amount not only limit said method, this non-the application Emphasis, repeats no more.

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 Downward to determine average Doppler frequency shift amount corresponding to described thumb upwards gesture and described thumb A value between the average Doppler frequency shift amount that gesture is corresponding is as described reference threshold.

In one embodiment, described step S1412b ' may further include:

S14121b ': in response to described Doppler frequency shift amount less than described reference threshold, determine institute Stating gesture-type is thumb upwards gesture.

As it was noted above, Doppler frequency shift amount corresponding to thumb upwards gesture can be downward higher than thumb The Doppler frequency shift amount that gesture is corresponding.In this step, described gesture-type otherwise be thumb to Upper gesture, or it is the downward gesture of thumb, in described Doppler frequency shift amount less than described with reference to threshold In the case of value, it may be determined that described gesture-type is thumb upwards gesture.

It is similar to, described step S1412b ' may further include:

S14122b ': in response to described Doppler frequency shift amount more than described reference threshold, determine institute Stating gesture-type is the downward gesture of thumb.

S150b: one second Doppler adjacent after obtaining described first Doppler measurement information Metrical information；

S160b: determine described second Doppler measurement information according to described Doppler's reference information Corresponding gesture-type；

S170b: in response to gesture-type corresponding to described second Doppler measurement information with described The gesture-type of target gesture is identical, it is determined that the execution duration of described target gesture includes described Time corresponding to the first Doppler measurement information is corresponding with described second Doppler measurement information Time.

Wherein, described second Doppler measurement information that is to say the Doppler measurement of the second time period Information.Described second time period can be identical with described first time period or close.

The gesture-type obtained in described step S140b i.e. described first Doppler measurement letter 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.

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 the most adjacent after should gathering and determine described first Doppler measurement information 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 Frequency domain information.As shown in Figure 10, it is assumed that experiment first obtains the LDF of C1 time period 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.

S190b: 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.

In addition to the gesture-type determining described target gesture and execution duration, described method is also May determine that the execution number of times of described target gesture.In one embodiment, described method is also May include that

S200b: one second Doppler adjacent after obtaining described first Doppler measurement information Metrical information；

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:

S230b: in response to gesture-type corresponding to described second Doppler measurement information with described The gesture-type of target gesture is identical, then adjacent after obtaining described second Doppler measurement information A Tridoppler metrical information；

S240b: determine described Tridoppler metrical information according to described Doppler's reference information Corresponding gesture-type；

S250b: in response to gesture-type corresponding to described Tridoppler metrical 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.

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.

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 Relation can preset, and such as its corresponding relation can be as shown in table 2.

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 Method can be with statistic switch lamp number of times, the electric light being not turned off to remind user to close.

It will be understood by those skilled in the art that in above-mentioned embodiment, substantially first according to institute State the first blood flow information and determine described gesture-type, and then determine described first input information, also That is, it is according to described first blood flow information, described gesture-type and described first defeated Enter the first corresponding relation between information and determine described first input information；In practice for described For the execution equipment of method or described method, it need not understand described gesture-type completely, It is to say, its can directly according to described first blood flow information and described first input information it Between the second corresponding relation determine described first input information.Certainly, for a user, its Still being necessary to understand described first corresponding relation, to perform different gestures, and then input is not Same information.
