S120: the finger in response to user performs a push action to an object, obtains described
The blood flow information of finger.
Wherein, described finger can be arbitrary finger of user, such as forefinger, thumb etc..Institute
Stating object can be an arbitrary interface contacted, and can be such as display screen, any material
Desktop, the back side of mobile phone, the surface etc. of glass.
Described blood flow information can be BVF (Blood Volume Flow, blood volume flow)
Information, it can be obtained by corresponding blood flow transducer, and described blood flow transducer is such as one
Ultrasonic array.
Fig. 2 is the BVF collected during forefinger flicking one object in one embodiment of the application
The oscillogram of information, wherein the waveform above dotted line is the waveform of corresponding flicking action, can see
Arrive, when user's flicking, the range value of BVF waveform can be caused to occur significantly and rise, its
The range value of peak is significantly greater than the range value of the crest of blood flow waveform when not pressing.
The BVF that collects when Fig. 3 is that in one embodiment of the application, forefinger is heavily by described object
The oscillogram of information, wherein the waveform above dotted line is corresponding heavily by the waveform of action, can see
Arriving, when user is heavy on time, significantly raising occurs in the range value also resulting in BVF waveform,
And its elevated-levels is much larger than elevated-levels during flicking in Fig. 2.
Wherein, described heavy finger on time to described object by surging, during more than described flicking
Finger to described object by surging.
It will be seen that when user with different by surging pressing same target time, blood can be caused
Stream waveform occurs that range value in various degree raises, and the application is based on this principle and realizes institute
State the identification of the first input information.
S140: determine one first input information according at least to described blood flow information.
In one embodiment, described step S140 may include that
S141: determine the dynamics information of described push action according at least to described blood flow information；
S142: determine the described first input information that described dynamics information is corresponding.
In described step S141, the dynamics information of described push action can be described by pressing
The maximum dynamics made, it is also possible to be multiple dynamics values of multiple time points during pressing.
In described step S142, right between described dynamics information and described first input information
Should be related to it can is predetermined.As a example by described dynamics information presses surging for maximum, its
Corresponding relation can be as shown in table 1.Assume that an intelligence ring and an intelligent glasses communicate, intelligence
Energy ring obtains user and presses the dynamics of desktop, recognizes a maximum by surging at intelligence ring
In the case of 8 Ns, it can control intelligent glasses and open APP (application) selection menu,
And automatically switch between each APP；When intelligence ring recognize another maximum of user by
When surging is less than 8 Ns, currently displaying APP is selected.Relation table shown in table 1 can

| Maximum presses surging | Input information |
| 8 Ns or less than 8 Ns | Choose order |
| More than 8 Ns | Open menu |
It addition, described dynamics information include multiple moment by surging in the case of, permissible
Described first input information is determined by surging according at least to two moment.Such as, it is assumed that press
After pressing off the beginning the 0.2nd second be 1 N by surging, maximum dynamics is 13 Ns, then with both
Dynamics input of difference 12 Niu Zuowei electronic billiard game.
In one embodiment, described step S141 may include that
S1411: determine a target waveform in described blood flow information, each on described target waveform
The range value of point is above a threshold value；
S1412: the range value the most a little less according to described target waveform and a reference information are true
The dynamics information of fixed described push action.
In described step S1411, described threshold value is used for detecting whether described blood flow waveform occurs bright
Aobvious range value raises, and it can be true according to the peak amplitude value of blood flow waveform when not pressing
Fixed, the most described threshold value is apparently higher than described peak amplitude value, such as by blood flow when not pressing
The peak amplitude value of waveform increases by 10% range value obtained as described threshold value.It is thus possible to
Determine higher than the blood flow waveform of described threshold portion owing to described push action causes.
As a example by Fig. 2, described threshold value can be first threshold th1, and described target waveform is
Portion waveshape on described th1.As a example by Fig. 3, described threshold value can be Second Threshold th2,
Described target waveform is the portion waveshape on th2.
In described step S1412, described reference information can be multiple reference frame angle value and multiple
With reference to the corresponding relation between dynamics, this corresponding relation can be predetermined by such as training.
In one embodiment, described step S1412 may further include:
S1412 ': range value and described reference information according to the wave crest point of described target waveform are true
The maximum dynamics of fixed described push action.
The wave crest point of described target waveform that is to say the peak of described target waveform, and it is also institute
State the point that range value in target waveform is maximum, its correspondence maximum dynamics of described push action.
In other words, when described push action by surging maximum time, the amplitude of described target waveform
Value rises to maximum, afterwards, keeps constant or be gradually reduced when described by surging, all can
The range value causing described target waveform is gradually reduced.Thus, according to the amplitude of described wave crest point
Value and described reference information can obtain the maximum dynamics of described push action.As a example by Fig. 3,
Range value according to v2 point can obtain the maximum dynamics of described push action, and binding time is believed
Breath, can obtain in the t ' moment maximum by surging.
It addition, it will be appreciated by those skilled in the art that according to wave crest point described in described target waveform it
Before waveform, can obtain multiple the most in the same time, described push action by surging.To scheme
As a example by 3, t can be obtained according to range value and the described reference information of p point in Fig. 3

Two input information.
In one embodiment, this step S160 may include that
S161: according to described dynamics information and the temporal information of described blood flow information, determine a power

Reach described maximum by the time of surging from starting to be pressed into, be calculated.In theory, institute
State and start time of pressing and can determine according to described target waveform, but, in practical operation really
This time starting pressing fixed may cause bigger operand, simple for the sake of, can be by described
Blood flow waveform rises to the time of described threshold value as the time starting pressing.As a example by Fig. 3,
It is then as the described time starting pressing using the time corresponding for s point.
It addition, described dynamics pace of change information can also is that pressing during multiple time points
Dynamics pace of change, it can obtain by differentiating the dynamics information of corresponding time point.
In described step S162, described dynamics pace of change information and described second input information
Between corresponding relation can be predetermined.For the sake of Jian Dan, only with described dynamics change speed
Degree information be described push action average dynamics pace of change value as a example by illustrate, such as,
Assume that described average dynamics pace of change value is higher than a predetermined threshold, then it is assumed that this push action is
Rapid, the second corresponding input information can be directly to open certain APP (application)；Instead
It, if described average dynamics pace of change value is less than described predetermined threshold, then it is assumed that this pressing
Action is gentle, and the second corresponding input information can simply be chooses this APP.
Clearer in order to describe, in above-mentioned embodiment, substantially according to described dynamics
The temporal information of information and described blood flow information determines described dynamics pace of change information, Jin Ergen
Determining described second input information according to described dynamics pace of change information, the most described dynamics is believed
Breath, the temporal information of described blood flow information, described dynamics pace of change information and described second defeated
Enter and there is between information one the 3rd corresponding relation.It will be appreciated by those skilled in the art that for described side
For the execution equipment of method, it can be concerned about described dynamics pace of change information completely, also
That is, its can directly according to described dynamics information, the temporal information of described blood flow information and

Below with reference to detailed description of the invention, describe the merit of described step S420 and S440 in detail
Energy.
S420: the finger in response to user performs a sliding action to an object, obtains described
The blood flow information of finger.
Wherein, described finger can be arbitrary finger of user, such as forefinger, thumb etc..Institute
Stating object can be an arbitrary interface contacted, and can be such as display screen, any material
Desktop, the back side of mobile phone, the surface etc. of glass.Described sliding action refers to that described finger exists
While keeping contacting with the surface of described object, change the relative position of finger and described object,
Such as move finger to a direction.
Described blood flow information can be BVF information, and it can pass through corresponding blood flow transducer
Obtaining, described blood flow transducer is such as a ultrasonic array.
When Fig. 5 is that in one embodiment of the application, forefinger slides on an object with low-force degree
The oscillogram of the blood flow information collected, wherein the waveform in dashed rectangle is corresponding sliding process
Waveform, it can be seen that (or perhaps right with described when user presses on described object
During as coming into contact with), the range value of blood flow waveform can be caused to occur significantly and to raise, be increased to
After wave crest point v1, it is gradually reduced, then as finger slip on described object, goes out
The concussion up and down of existing certain amplitude, until finger leaves object, gradually recovers normal blood flow ripple
Shape.
Fig. 6 is that in one embodiment of the application, forefinger slides on described object with large force degree
Time the oscillogram of blood flow information that collects, wherein the waveform in dashed rectangle is that correspondence was slided
The waveform of journey, it can be seen that when user presses on described object (or perhaps with described
When object comes into contact with), also cause the range value of blood flow waveform to occur significantly and raise, raise
After wave crest point v2, it is gradually reduced, then as finger slip on described object,
The concussion up and down of certain amplitude occurs, until finger leaves object, gradually recovers normal blood flow
Waveform.
Comparison diagram 5 and Fig. 6 is it will be seen that work as user and slide on described object with less dynamics
Time dynamic, the degree ratio that blood flow waveform shakes up and down is more serious, and shock range is bigger in other words；And
When the dynamics that user one is bigger is slided on described object, the degree that blood flow waveform shakes up and down
Smaller, shock range is less in other words, in figure 6 it can be seen that in its dashed rectangle
Waveform is the most linearly.The application is based on this principle and realizes the identification to described input information.
S440: determine an input information according at least to described blood flow information.
In one embodiment, this step S440 may include that
S441: determine the dynamics information of described sliding action according at least to described blood flow information；
S442: determine the described input information that described dynamics information is corresponding.
In described step S441, the dynamics information of described sliding action can be that described slip is moved
The mean force angle value of the sliding process made.
Corresponding pass in described step S442, between described dynamics information with described input information
System can be predetermined, such as, when the value of described dynamics information is less than 5 Ns, to should
Front e-book turns over page 1；When the value of described dynamics information is more than 5 Ns, and corresponding Current electronic book turns over
Page two.
It addition, in actual applications, each sliding action necessarily includes pressing when starting
Action, the dynamics information of described sliding action can also be with the dynamics of the push action before sliding
Information combines, to be combined into more input information.
In one embodiment, described step S441 may include that
S4411: determine one first blood flow that finger sliding process is corresponding in described blood flow information
Information；
S4412: according at least to the one first range value standard deviation that described first blood flow information is corresponding
Determine the dynamics information of described sliding action.
In described step S4411, described first blood flow information mainly includes that finger is described right
As surface starts to produce relative position change, to stopping the relative position change of generation, this process
Corresponding blood flow information, the blood flow information that the most described sliding process is corresponding, it does not wraps
Blood flow information corresponding when including finger down and lift.As a example by Fig. 6, it is simply that dotted line in Fig. 6
The blood flow waveform that square frame is corresponding.The determination of this portion waveshape can to use the modes such as such as threshold method,
A predetermined amplitude value is dropped to from the maximum amplitude value that v2 point is corresponding than blood flow waveform as will be described
The starting point of the first blood flow information described in Shi Zuowei, rises the range value of blood flow waveform after starting point
Or decline amount more than during a scheduled volume as the terminal of described first blood flow information.
In described step S4412, such as can calculate described first range value by below equation
Standard deviation sigma1:
Wherein, xiRepresenting the range value of ith sample point, n represents described first blood flow information
In the quantity of all sampled points that comprises,Represent the averaged amplitude value of described n sampled point.
Inventor finds in research process, the range value standard deviation of blood flow information, reflection be
The dispersion degree of blood flow information range value.When slip great efforts, the blood vessel degree that is squeezed is big,
The range value change of blood flow information is little, and standard deviation is little；When pressing power and being little, blood vessel is squeezed
Degree is little, and the range value change of blood flow information is relatively large, and standard deviation is big.It is to say, it is described
First range value standard deviation is inverse ratio with the value of described dynamics information.
Therefore, in described step S4412, can be according to described first range value standard deviation and
Reference information determines the dynamics information of described sliding action.Described reference information can include multiple
Corresponding relation between reference frame angle value standard deviation and multiple reference dynamics information, it can pass through
Training in advance determines.
It addition, inventor also finds, the condition of user is likely to can be to described first amplitude
