Specific embodiment

With reference to the accompanying drawings and examples, the specific embodiment of the application is described in further detail.Implement below Example is not limited to scope of the present application for illustrating the application.

It will be appreciated by those skilled in the art that the size of the serial number of following each steps is not intended in embodiments herein Execution sequence it is successive, the execution of each step sequence should be determined by its function and internal logic, and implement without coping with the application The implementation process of example constitutes any restriction.

Inventor has found in the course of the research, if the hand of user executes different gestures, will lead to the blood flow of hand There is apparent variation in information.Based on this, the blood flow information detected according to sensor can then identify the gesture of user, into And it can determine the corresponding input information of corresponding gesture.Wherein, the blood flow information can be PPG (photoplethysmography, photoplethysmographic) information, or can also be Doppler measurement information, such as LDF (Laser Doppler Flowmetry, laser-Doppler flow velocity) information.

Fig. 1 is the flow chart of exchange method described in the application one embodiment, and the method can be set in such as one interaction Standby upper realization.As shown in Figure 1, which comprises

S120: executing a target gesture in response to the hand of a user, one first blood flow information obtained at the thumb, The target gesture is the upward gesture of thumb or the downward gesture of thumb；

S140: the gesture-type of the target gesture is determined according to first blood flow information and a reference information.

The embodiment of the present application the method executes a target gesture in response to the hand of a user, obtains at the thumb One first blood flow information is taken, the target gesture is the upward gesture of thumb or the downward gesture of thumb, then according to first blood Stream information and a reference information can determine the gesture-type of the target gesture.It is a kind of true according to blood flow information to provide Determine the exchange method of gesture-type, and corresponding input information may further determine that according to determining gesture-type, it is described Method is conducive to improve the input capability of the electronic equipments such as wearable device.

Below with reference to specific embodiment, the function of the step S120 and S140 is described in detail.

S120: executing a target gesture in response to the hand of a user, one first blood flow information obtained at the thumb, The target gesture is the upward gesture of thumb or the downward gesture of thumb.

Wherein, the blood flow information can such as be PPG information or Doppler measurement information, can be by corresponding Sensor acquisition obtains, for example can be acquired by PPG sensor and obtain the PPG information.First blood flow information can be with It is the corresponding blood flow information of first time period.

The upward gesture of the thumb namely thumbs-up gesture, as shown in Fig. 2, when user provides the gesture, four Finger gripping fist, thumb are upward.The downward gesture of the thumb namely thumbs-down gesture, as shown in figure 3, when user provides the hand When gesture, four finger gripping fists, thumb is downward.

In the step, the gesture-type of the target gesture is determined, namely determine that the target gesture is the upward hand of thumb Gesture or the downward gesture of thumb.

As it was noted above, the blood flow information can such as be PPG information or Doppler measurement in the step S140 Information will be illustrated in the case where PPG information or Doppler measurement information respectively to the blood flow information below.

A), in one embodiment, first blood flow information is the first PPG information, the corresponding step S140 Further are as follows:

S140a: the gesture-type of the target gesture is determined according to the first PPG information and a PPG reference information.

Fig. 4 is the waveform diagram of the collected PPG information at thumb when user executes thumb upward gesture.Fig. 5 is When user executes thumb downward gesture at thumb collected PPG information waveform diagram.It can see by comparison, when When user executes thumb upward gesture, the averaged amplitude value of obtained PPG information is higher, and when user executes the downward gesture of thumb When, the averaged amplitude value of obtained PPG information is lower.Therefore, herein described method can be according to collected at thumb The averaged amplitude value of PPG information, with identify user it is currently performed be the upward gesture of thumb or the downward gesture of thumb.Wherein, The averaged amplitude value of a certain PPG information can be by doing the range value of all sampled points in the PPG information and and divided by sampling The quantity of point, which calculates, to be determined.

Wherein, the first PPG information that is to say the PPG information of first time period, in order to preferably reflect The averaged amplitude value of one PPG information, the length of the first time period can be at least a PPG period, that is, be more than or equal to 0.8 Second；Meanwhile if the first time period is too long, may during this period of time user successively perform thumb upwards and thumb Downward two kinds of gestures may cause mistake at this time if identified according to a kind of gesture, and therefore, the first time period can To be less than or equal to the duration that user executes a kind of gesture, that is, it is less than or equal to 1 second.That is, the first time period can be situated between Between 0.8 second and 1 second.Certainly, if user is not used in mixed way two distinct types of gesture, the first time period It can be longer.For the sake of simplicity, the first time period can be set as a PPG period in the application, such as 0.8 second.

In one embodiment, the step S140a may include:

S140a ': the target gesture is determined according to the averaged amplitude value of the first PPG information and a reference threshold Gesture-type.

Wherein, the reference threshold can be a range value determining by training in advance.For example, user is performed a plurality of times The upward gesture of thumb collects multiple groups PPG information at thumb and the upward gesture correspondence of a thumb is calculated Averaged amplitude value；Then, the downward gesture of the thumb is performed a plurality of times in user, and multiple groups PPG letter is collected at thumb It ceases and the corresponding averaged amplitude value of the downward gesture of a thumb is calculated.In turn, it can determine that the upward gesture of the thumb is corresponding Averaged amplitude value and the corresponding averaged amplitude value of the downward gesture of the thumb between a range value as it is described refer to threshold Value.

In one embodiment, the step S140a ' may further include:

S141a ': it is greater than the reference threshold in response to the averaged amplitude value of the first PPG information, determines the gesture Type is the upward gesture of thumb.

As it was noted above, the averaged amplitude value of the corresponding PPG information of the upward gesture of thumb can be higher than the downward gesture pair of thumb The averaged amplitude value for the PPG information answered.In this step, the gesture-type or it is the upward gesture of thumb or is thumb Downward gesture can determine the hand in the case where the averaged amplitude value of the first PPG information is greater than the reference threshold Gesture type is the upward gesture of thumb.

Similar, the step S140a ' may further include:

S142a ': it is less than the reference threshold in response to the averaged amplitude value of the first PPG information, determines the gesture Type is the downward gesture of thumb.

In another embodiment, the step S140a may include:

S140a ": the target hand is determined according to the averaged amplitude value of the first PPG information and an at least reference interval The gesture-type of gesture.

Wherein, the reference interval is a range value section, can train determination in advance.For example, user is performed a plurality of times The upward gesture of thumb, collects multiple groups PPG information at thumb, calculates separately to obtain according to every group of PPG information Then one averaged amplitude value can determine the corresponding reference area of the upward gesture of thumb according to maximum value therein and minimum value Between；Similar, the downward gesture of the thumb is performed a plurality of times in user, multiple groups PPG information is collected at thumb, according to every Group PPG information calculate separately to obtain an averaged amplitude value, then according to maximum value therein and minimum value can determine thumb to The corresponding another reference interval of lower gesture.

In one embodiment, the step S140a " may include:

S141a ": belong to the first reference interval in response to the averaged amplitude value of the first PPG information, determine the gesture Type is the upward gesture of thumb.

As it was noted above, first reference interval can be the corresponding reference of the upward gesture of thumb that training is determining in advance Section can determine the gesture when the averaged amplitude value of the first PPG information detected belongs to the first interval Type is the upward gesture of thumb.

Similar, the step S140a " may include:

S142a ": belong to the second reference interval in response to the averaged amplitude value of the first PPG information, determine the gesture Type is the downward gesture of thumb.

As it was noted above, second reference interval can be the corresponding reference of the downward gesture of thumb that training is determining in advance Section.

The gesture-type of the target gesture is identified by the way of the reference interval, although processing complexity Known otherwise higher than above-mentioned according to reference threshold, still, the accuracy of this mode is higher, and convenient for increasing in the future The gesture-type that can be identified has reserved space for the upgrading of method.

After the gesture-type that the target gesture has been determined, the method can also further determine that the target hand The execution duration of gesture.In one embodiment, the method can also include:

S150a: one the 2nd adjacent PPG information after acquisition the first PPG information；

S160a: the corresponding gesture-type of the 2nd PPG information is determined according to the PPG reference information；

S170a: in response to the gesture-type phase of the 2nd PPG information corresponding gesture-type and the target gesture Together, it is determined that the execution duration of the target gesture includes the first PPG information corresponding time and the 2nd PPG information The corresponding time.

Wherein, the 2nd PPG information that is to say the PPG information of second time period.The second time period can be with institute It is identical or close to state first time period.

The gesture-type determined in the step S140a is it can be appreciated that be the corresponding gesture of the first PPG information Type.The realization principle of the step S160a can be identical as the realization principle of the step S140a, repeats no more.

In the step S170a, if the gesture of the 2nd PPG information corresponding gesture-type and the target gesture Type is identical, then it represents that user is always maintained at the mesh in the time range of the first time period and the second time period Gesture is marked, i.e., the execution duration of the described target gesture includes the first PPG information corresponding time and the 2nd PPG information The corresponding time.

It will be appreciated by those skilled in the art that the exact value of the execution duration of the target gesture, the method are answered in order to obtain The corresponding gesture-type of 2nd PPG information successively adjacent, the 3rd PPG letter after the acquisition and the determining first PPG information Corresponding gesture-type ... is ceased, until obtaining a PPG information different from the gesture-type of the target gesture, Wo Menke To be referred to as to end PPG information, then from the first PPG information corresponding time, until the time before cut-off PPG information Length is the execution duration of the target gesture.

Therefore, in one embodiment, the method can also include:

S180a: not in response to the gesture-type of the corresponding gesture-type of the 2nd PPG information and the target gesture Together, it is determined that the execution duration of the target gesture is equal to the first PPG information corresponding time.

That is, if the 2nd PPG information is exactly the cut-off PPG information, the execution of the target gesture Duration just just when described in the first PPG information corresponding time.

In order to be further illustrated, PPG waveform shown in fig. 6 can be referred to.As shown in Figure 6, it is assumed that first obtained in experiment The PPG information for having taken the C1 period determines that the corresponding gesture-type of C1 is the upward gesture of thumb according to its averaged amplitude value；Then The PPG information of C2 period is obtained, determines that its corresponding gesture-type is also the upward gesture of thumb after calculation process, it is therefore desirable to Further determine that C3 period corresponding gesture-type；Then the PPG information of C3 period is obtained, determines that its is right after calculation process The gesture-type answered also is the upward gesture of thumb, it is therefore desirable to further determine that C4 period corresponding gesture-type；Then it obtains The PPG information of C4 period is taken, determines that its corresponding gesture-type is the downward gesture of thumb after calculation process, it is thus determined that described The sum of a length of C1, C2, C3 corresponding time when the execution of the upward gesture of thumb.

By above-mentioned processing, the method can finally obtain the execution duration of the target gesture, and when the execution Length can correspond to different input information.Therefore, in one embodiment, the method can also include:

S190a: the corresponding one first input information of the execution duration of the target gesture is determined.

Wherein, the corresponding relationship between the execution duration of the target gesture and the first input information can be set in advance It is fixed, for example its corresponding relationship can be as shown in Table 1 below.By in table 1 the first row record for, when target gesture be thumb to On, and execute duration less than 1.5 seconds when, it is described first input information can for open order, such as open TV；Second row note For record, when target gesture is upward for thumb, and executes duration greater than 2 seconds, the first input information can be to cut forward Order is changed, for example television channel is switched towards the direction for being less than current frequency channel number.

Table 1

Target gesture	Execute duration	First input information
			Thumb is upward	Less than 1.5 seconds	It opens
Thumb is upward	Greater than 2 seconds	Switch forward

Thumb is downward	Less than 1.5 seconds	It closes
			Thumb is downward	Greater than 2 seconds	Switch backward

Other than in addition to the gesture-type of the determination target gesture and executing duration, the method can also determine the mesh Mark the execution number of gesture.In one embodiment, the method can also include:

S200a: one the 2nd adjacent PPG information after acquisition the first PPG information；

S210a: the corresponding gesture-type of the 2nd PPG information is determined according to the PPG reference information；

S220a: not in response to the gesture-type of the corresponding gesture-type of the 2nd PPG information and the target gesture Together, it is determined that the execution number of the target gesture increases primary.

The realization principle of the step S200a is identical with the step S150a realization principle, repeats no more.

The realization principle of the step S210a is identical with the step S160a realization principle, repeats no more.

In the step S220a, the execution number of the target gesture can have an initial value, which can be with It is 0.In the step, the method can acquire and determine the 2nd PPG information pair successively adjacent after the first PPG information Gesture-type, the corresponding gesture-type ... of the 3rd PPG information answered, until obtaining the gesture class of one with the target gesture The different PPG information of type, we can be referred to as cut-off PPG information, then from the first PPG information corresponding time, until In time before cut-off PPG information, the user is executing always same gesture, and before the cut-off PPG information At the time of just complete the primary target gesture.Therefore, in the step S220a, if the 2nd PPG information is corresponding Gesture-type it is different from the gesture-type of the target gesture, then it represents that the user completes the primary target gesture, It is primary to may thereby determine that the execution number of the target gesture increases, that is, the execution of the target gesture is this time become by zero It is 1.

In addition, if the corresponding gesture-type of the 2nd PPG information is identical as the gesture-type of the target gesture, It indicates within the 2nd PPG information corresponding time, user is still executing the target gesture.To which the method is also May include:

S230a: in response to the gesture-type phase of the 2nd PPG information corresponding gesture-type and the target gesture Together, then adjacent one the 3rd PPG information after the 2nd PPG information is obtained；

S240a: the corresponding gesture-type of the 3rd PPG information is determined according to the PPG reference information；

S250a: not in response to the gesture-type of the corresponding gesture-type of the 3rd PPG information and the target gesture Together, it is determined that the execution number of the target gesture increases primary.

That is, identical as the gesture-type of the target gesture in the corresponding gesture-type of the 2nd PPG information In the case where, need further to judge the corresponding gesture-type of the 3rd PPG information.If the 3rd PPG information is corresponding Gesture-type it is different from the gesture-type of the target gesture, then it represents that user completes the primary target gesture, thus institute The execution number for stating target gesture increases once；, whereas if the corresponding gesture-type of the 3rd PPG information and the target The gesture-type of gesture is also identical, then needs further to judge the corresponding hand of the 4th PPG information after the 3rd PPG information Gesture type, and so on, until finding a PPG information different from the gesture-type of the target gesture, i.e. cut-off PPG believes Breath, the execution number of the target gesture becomes 1 from zero at this time.

Similar, after the cut-off PPG information, when the gesture-type and the target for occurring a PPG information again When the gesture-type of gesture is identical, can mark the PPG information is the first new PPG information, then repeats the above steps, finds One new cut-off PPG information, the execution number of the target gesture increases once again at this time, i.e., becomes 2 from 1.Successively class It pushes away, the method can obtain the total degree that user in one section of predetermined time executes the target gesture, i.e., according to user demand The execution number of the target gesture finally determined.

It, can be still referring to shown in Fig. 6 in order to be further illustrated the execution number for how determining the target gesture PPG waveform.As shown in Figure 6, it is assumed that user needs to obtain the execution time that the upward gesture of thumb is executed in C1~C6 this period Number.Then as it was noted above, determining the upward gesture of the thumb when determining the corresponding gesture-type of C4 is the downward gesture of thumb It executes number to increase once, i.e., becomes 1 from 0；It then proceedes to determine the corresponding gesture-type of C5, it is found that its gesture-type is thumb Upward gesture；Then, it further determines that the corresponding gesture-type of C6, it is found that its gesture-type is the downward gesture of thumb, thus really The execution number of the fixed upward gesture of thumb increases once, i.e., becomes 2 from 1, and finally determine the upward gesture of the thumb Executing number is 2.

By above-mentioned processing, the method can finally obtain the execution number of the target gesture, and the execution is secondary Number can correspond to different input information.Therefore, in one embodiment, the method can also include:

S260a: the corresponding one second input information of the execution number of the target gesture is determined.

Wherein, the corresponding relationship between the execution number of the target gesture and the second input information can be set in advance It is fixed, for example its corresponding relationship can be as shown in Table 2 below.By in table 2 the first row record for, when target gesture be thumb to On, and execute number be 1 when, it is described second input information can for open order, such as open TV；Second row is recorded as Example, when target gesture is upward for thumb, and execution number is 2, the second input information can order for volume increase.

Table 2

Target gesture	Execute number	Second input information
			Thumb is upward	1	It opens
Thumb is upward	2	Volume increases
			Thumb is downward	1	It closes
Thumb is downward	2	Volume is reduced

In addition to as shown in table 2, the corresponding second input information of the execution number of the target gesture can also be by a wearing Formula equipment voluntarily determines after calculation process, for example, user go back home at night in by the intelligence in the upward gesture control man of thumb Electric light is opened, and the upward gesture of thumb of every execution opens an electric light；Then, when user prepares during sleep, to pass through thumb Downward gesture control electric light is closed, and the downward gesture of thumb of every execution closes an electric light.To which the method can be by institute The number of user's execution upward gesture of thumb is stated as a reference value, then, judges that user executes time of the downward gesture of thumb Whether number, which is less than the reference value, if it is less than the reference value then shows that the electric light having is not turned off, and then can be to not closed The electric light closed inputs a flash command, and electric light starts flashing 5 seconds, to remind user to close the electric light.

B), in another embodiment, first blood flow information is the first Doppler measurement information, the Doppler Metrical information can such as be that (how general Laser Doppler Velocimetry, laser is by LDF (laser Doppler shift), LDV Le tests the speed), supersonic Doppler frequency displacement etc. comprising a series of Envelop waves signal carries out such as fast Fourier change to it Available corresponding frequency-region signal is changed, the Doppler frequency shift amount in the frequency-region signal is proportional to blood flow velocity.To when pair When the range value for the PPG information answered is lower, show that blood flow velocity increases, then the Doppler frequency shift amount in the frequency-region signal is got over Greatly；When the range value of corresponding PPG information is higher, show that blood flow velocity reduces, then Doppler's frequency in the frequency-region signal Shifting amount is smaller.

The corresponding step S140 is further are as follows:

In one embodiment, the step S142b may include:

S142b ': the gesture-type of the target gesture is determined according to the Doppler frequency shift amount and a reference threshold.

Wherein, the reference threshold can be a Doppler frequency shift amount determining by training in advance.For example, user is more It is secondary to execute the upward gesture of thumb, multiple groups LDF information is collected at thumb, is calculated after carrying out frequency domain conversion respectively Corresponding Doppler frequency shift amount, calculates its average value then to obtain the corresponding average Doppler frequency shift of the upward gesture of a thumb Amount；Then, the downward gesture of the thumb is performed a plurality of times in user, and multiple groups LDF information is collected at thumb, is carried out respectively Corresponding Doppler frequency shift amount is calculated after frequency domain conversion, it is corresponding flat to obtain the downward gesture of a thumb then to calculate its average value Equal Doppler frequency shift amount.In turn, the corresponding average Doppler frequency shift amount of the upward gesture of the thumb and the thumb can be determined A value between the corresponding average Doppler frequency shift amount of downward gesture is used as the reference threshold.

In one embodiment, the step S142b ' may further include:

S1421b ': being less than the reference threshold in response to the Doppler frequency shift amount, determines that the gesture-type is thumb Upward gesture.

As it was noted above, the corresponding Doppler frequency shift amount of the upward gesture of thumb can be corresponding how general higher than the downward gesture of thumb Strangle frequency shift amount.In this step, the gesture-type or it is the upward gesture of thumb or is the downward gesture of thumb, described In the case that Doppler frequency shift amount is less than the reference threshold, it can determine that the gesture-type is the upward gesture of thumb.

Similar, the step S142b ' may further include:

S1422b ': being greater than the reference threshold in response to the Doppler frequency shift amount, determines that the gesture-type is thumb Downward gesture.

In another embodiment, the step S142b may include:

S142b ": the gesture class of the target gesture is determined according to the Doppler frequency shift amount and at least a reference interval Type.

Wherein, the reference interval is a Doppler frequency shift amount section, can train determination in advance.For example, user is more It is secondary to execute the upward gesture of thumb, multiple groups LDF information is collected at thumb, it is corresponding according to every group of LDF information Frequency domain information calculates separately to obtain a Doppler frequency shift amount, then according to maximum value therein and minimum value can determine thumb to The corresponding reference interval of upper gesture；Similar, the downward gesture of the thumb is performed a plurality of times in user, acquires at thumb To multiple groups LDF information, calculate separately to obtain a Doppler frequency shift amount according to the corresponding frequency domain information of every group of LDF information, then root The corresponding another reference interval of the downward gesture of thumb can be determined according to maximum value therein and minimum value.

In one embodiment, the step S142b " may include:

S1421b ": belonging to the first reference interval in response to the Doppler frequency shift amount, determines that the gesture-type is thumb Upward gesture.

As it was noted above, first reference interval can be the corresponding reference of the upward gesture of thumb that training is determining in advance Section.

Similar, the step S142b " may include:

S1422b ": belonging to the second reference interval in response to the Doppler frequency shift amount, determines that the gesture-type is thumb Downward gesture.

S150b: one second adjacent Doppler measurement information after acquisition the first Doppler measurement information；

S160b: the corresponding gesture-type of the second Doppler measurement information is determined according to Doppler's reference information；

S170b: in response to the gesture of the second Doppler measurement information corresponding gesture-type and the target gesture Type is identical, it is determined that the execution duration of the target gesture includes the first Doppler measurement information corresponding time and institute State the second Doppler measurement information corresponding time.

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

Gesture-type obtained in the step S140b i.e. the corresponding gesture class of the first Doppler measurement information Type.The realization principle of the step S160b can be identical as the realization principle of the step S140b, repeats no more.

In the step S170b, if the corresponding gesture-type of the second Doppler measurement information and the target hand The gesture-type of gesture is identical, then it represents that user protects always in the time range of the first time period and the second time period Hold the target gesture, i.e., the execution duration of the described target gesture include the first Doppler measurement information corresponding time and The second Doppler measurement information corresponding time.

It will be appreciated by those skilled in the art that the exact value of the execution duration of the target gesture, the method are answered in order to obtain The corresponding gesture of second Doppler measurement information successively adjacent after the acquisition and the determining first Doppler measurement information Type, the corresponding gesture-type ... of third Doppler measurement information, until obtaining the gesture class of one with the target gesture The different Doppler measurement information of type, we can be referred to as cut-off Doppler measurement information, then survey from first Doppler From measuring the information corresponding time, until the time span before the cut-off Doppler measurement information is the execution of the target gesture Duration.

Therefore, in one embodiment, the method can also include:

S180b: in response to the gesture of the second Doppler measurement information corresponding gesture-type and the target gesture Type is different, it is determined that the execution duration of the target gesture is equal to the first Doppler measurement information corresponding time.

That is, if the second Doppler measurement information is exactly the cut-off Doppler measurement information, it is described The execution duration of target gesture is just just the first Doppler measurement information corresponding time.

In order to be further illustrated, LDF waveform shown in Fig. 10 and its corresponding frequency domain information can be referred to.Such as Figure 10 It is shown, it is assumed that the LDF information that the C1 period is first obtained in experiment is converted to corresponding frequency domain below dotted line by frequency domain and believes Breath, and then determine that the corresponding gesture-type of C1 is the upward gesture of thumb according to its Doppler frequency shift amount；Then the C2 period is obtained LDF information, determine that its corresponding gesture-type is also the upward gesture of thumb after calculation process, it is therefore desirable to further determine that C3 Period corresponding gesture-type；Then the LDF information of C3 period is obtained, determines its corresponding gesture-type after calculation process It also is the upward gesture of thumb, it is therefore desirable to further determine that C4 period corresponding gesture-type；Then the C4 period is obtained LDF information determines that its corresponding gesture-type is the downward gesture of thumb after calculation process, it is thus determined that the upward gesture of the thumb Execution when the sum of a length of C1, C2, C3 corresponding time.

S190b: the corresponding one first input information of the execution duration of the target gesture is determined.

Wherein, the corresponding relationship between the execution duration of the target gesture and the first input information can be set in advance It is fixed, for example its corresponding relationship can be as shown in Table 1 below.

S200b: one second adjacent Doppler measurement information after acquisition the first Doppler measurement information；

S210b: the corresponding gesture-type of the second Doppler measurement information is determined according to Doppler's reference information；

S220b: in response to the gesture of the second Doppler measurement information corresponding gesture-type and the target gesture Type is different, it is determined that the execution number of the target gesture increases primary.

The realization principle of the step S200b is identical with the step S150b realization principle, repeats no more.

The realization principle of the step S210b is identical with the step S160b realization principle, repeats no more.

In the step S220b, the execution number of the target gesture can have an initial value, which can be with It is 0.In the step, the method can acquire and determine after the first Doppler measurement information successively adjacent more than second The corresponding gesture-type of general Le metrical information, the corresponding gesture-type ... of third Doppler measurement information, until obtaining one The Doppler measurement information different from the gesture-type of the target gesture, we can be referred to as cut-off Doppler measurement letter Breath, then from the first Doppler measurement information corresponding time, until in time before the cut-off Doppler measurement information, The user is executing always same gesture, and before cut-off Doppler measurement information at the time of just completes primary institute State target gesture.Therefore, in the step S220b, if the corresponding gesture-type of the second Doppler measurement information with The gesture-type of the target gesture is different, then it represents that the user completes the primary target gesture, may thereby determine that The execution number of the target gesture increases once, that is, the execution of the target gesture this time becomes 1 from zero.

In addition, if the gesture-type of the second Doppler measurement information corresponding gesture-type and the target gesture It is identical, then it represents that within the second Doppler measurement information corresponding time, user is still executing the target gesture.From And the method can also include:

S230b: in response to the gesture of the second Doppler measurement information corresponding gesture-type and the target gesture Type is identical, then obtains an adjacent third Doppler measurement information after the second Doppler measurement information；

S240b: the corresponding gesture-type of the third Doppler measurement information is determined according to Doppler's reference information；

S250b: in response to the gesture of the third Doppler measurement information corresponding gesture-type and the target gesture Type is different, it is determined that the execution number of the target gesture increases primary.

That is, in the gesture class of the second Doppler measurement information corresponding gesture-type and the target gesture In the identical situation of type, need further to judge the corresponding gesture-type of the third Doppler measurement information.If described The corresponding gesture-type of Tridoppler metrical information is different from the gesture-type of the target gesture, then it represents that user completes primary The target gesture, so that the execution number of the target gesture increases once；, whereas if the third Doppler measurement letter It is also identical as the gesture-type of the target gesture to cease corresponding gesture-type, then needs further to judge the third Doppler The corresponding gesture-type of the 4th Doppler measurement information after metrical information, and so on, until finding one and the mesh Mark the different Doppler measurement information of gesture-type of gesture, i.e. cut-off Doppler measurement information, at this time the target gesture Executing number becomes 1 from zero.

Similar, after the cut-off Doppler measurement information, when the gesture for occurring a Doppler measurement information again When type is identical as the gesture-type of the target gesture, can mark the Doppler measurement information is that the first new Doppler surveys Information is measured, then repeats the above steps, finds a new cut-off Doppler measurement information, the at this time execution of the target gesture Number increases once again, i.e., becomes 2 from 1.And so on, the method can obtain one section of pre- timing according to user demand Interior user executes the total degree of the target gesture.

It, can be referring still to shown in Fig. 10 in order to further illustrate the execution number for how determining the target gesture LDF waveform and its corresponding frequency domain information.As shown in Figure 10, it is assumed that user, which needs to obtain, executes thumb in C1~C6 this period The execution number of upward gesture.Then as it was noted above, determining institute when determining the corresponding gesture-type of C4 is the downward gesture of thumb The execution number for stating the upward gesture of thumb increases once, i.e., becomes 1 from 0；It then proceedes to determine the corresponding gesture-type of C5, discovery Its gesture-type is the upward gesture of thumb；Then, it further determines that the corresponding gesture-type of C6, it is found that its gesture-type is thumb Downward gesture becomes 2 from 1 so that it is determined that the execution number of the upward gesture of the thumb increases primary, and described in finally determining The execution number of the upward gesture of thumb is 2.

S260b: the corresponding one second input information of the execution number of the target gesture is determined.

Wherein, the corresponding relationship between the execution number of the target gesture and the second input information can be set in advance It is fixed, for example its corresponding relationship can be as shown in table 2.

In addition to as shown in table 2, the corresponding second input information of the execution number of the target gesture can also be by a wearing Formula equipment voluntarily determines after calculation process, for example, user go back home at night in by the intelligence in the upward gesture control man of thumb Electric light is opened, and the upward gesture of thumb of every execution opens an electric light；Then, when user prepares during sleep, to pass through thumb Downward gesture control electric light is closed, and the downward gesture of thumb of every execution closes an electric light.To which the method can count Switch lamp number, the electric light being not turned off with reminding user to close.

In addition, in one embodiment, the method can with comprising steps of

S270: the corresponding third input information of the gesture-type is determined.

Wherein, the corresponding relationship between the gesture-type of the target gesture and third input information can be set in advance Determine, for example corresponding open of the upward gesture of thumb is ordered, the downward gesture of thumb corresponds to shutdown command.

First determining module 1120 determines that the realization of the corresponding gesture-type of the second Doppler measurement information is former Reason can determine that the realization principle of the corresponding gesture-type of the first Doppler measurement information is identical with it, repeat no more.

It will be appreciated by those skilled in the art that if the corresponding gesture-type of the second Doppler measurement information and the target The gesture-type of gesture is identical, then it represents that user in the time range of the first time period and the second time period always The target gesture is kept, i.e., the execution duration of the described target gesture includes the first Doppler measurement information corresponding time Time corresponding with the second Doppler measurement information.

The exact value of the execution duration of the target gesture, the method should acquire and determine described first in order to obtain The corresponding gesture-type of second Doppler measurement information successively adjacent, third Doppler measurement letter after Doppler measurement information Corresponding gesture-type ... is ceased, until obtaining a Doppler measurement letter different from the gesture-type of the target gesture Breath, we can be referred to as cut-off Doppler measurement information, then from the first Doppler measurement information corresponding time, until Time span before the cut-off Doppler measurement information is the execution duration of the target gesture.

Therefore, in one embodiment, the second determining module 1130b is also used to general in response to more than described second It is different from the gesture-type of the target gesture to strangle the corresponding gesture-type of metrical information, it is determined that the execution of the target gesture Duration is equal to the first Doppler measurement information corresponding time.

That is, if the second Doppler measurement information is exactly the cut-off Doppler measurement information, it is described The execution duration of target gesture is just just the first Doppler measurement information corresponding time.Otherwise, the acquisition module 1110 continue Doppler measurement information adjacent after obtaining, and the first acquisition module continues to determine its corresponding gesture class Type, if gesture-type is different from the gesture-type of the target gesture, the second determining module 1130b determines the mesh Mark the execution duration of gesture；If identical, aforesaid operations are repeated, until the second determining module 1130b determines the target The execution duration of gesture.

Referring to fig. 20, the equipment 1100 further include:

One third determining module 1150b, in response to the corresponding gesture-type of the second Doppler measurement information with The gesture-type of the target gesture is different, it is determined that the execution number of the target gesture increases primary.

The execution number of the target gesture can have an initial value, which can be 0.The equipment can be with The corresponding gesture class of second Doppler measurement information successively adjacent after acquisition and the determining first Doppler measurement information Type, the corresponding gesture-type ... of third Doppler measurement information, until obtaining the gesture-type of one with the target gesture Different Doppler measurement information, we can be referred to as cut-off Doppler measurement information, then from first Doppler measurement From the information corresponding time, until the user is executing always on the other hand in time before the cut-off Doppler measurement information Gesture, and the primary target gesture is just completed at the time of before the cut-off Doppler measurement information.Therefore, for third For determining module 1150b, if the hand of the second Doppler measurement information corresponding gesture-type and the target gesture Gesture type is different, then it represents that the user completes the primary target gesture, may thereby determine that holding for the target gesture Row number increases once, that is, the execution of the target gesture this time becomes 1 from zero.

In addition, if the gesture-type of the second Doppler measurement information corresponding gesture-type and the target gesture It is identical, then it represents that within the second Doppler measurement information corresponding time, user is still executing the target gesture.From And

The acquisition module 1110 is also used in response to the corresponding gesture-type of the second Doppler measurement information and institute The gesture-type for stating target gesture is identical, then obtains an adjacent third Doppler after the second Doppler measurement information and survey Measure information；

First determining module 1120 is also used to determine that the third Doppler surveys according to Doppler's reference information Measure the corresponding gesture-type of information；

The third determining module 1150b is also used to gesture class corresponding in response to the third Doppler measurement information Type is different from the gesture-type of the target gesture, it is determined that the execution number of the target gesture increases primary.

By above-mentioned processing, the equipment 1100 can finally obtain the execution number of the target gesture, and described hold Row number can correspond to different input information.Therefore, in one embodiment, still referring to Figure 20, the equipment 1100 Further include:
